Steel Chang'an

Chapter 117

Mu Yun walked in the darkness.

The terrain exposed after the tide receded made them realize that the water was likely to be formed naturally.The bottom of the bowl-shaped lake they are currently walking on should have been a huge underground salt lake, and the Donglin underground water system is scattered all over. The source of this underground lake is probably the East China Sea.

In other words, this ancient battlefield of the Millennium War was originally an underground lake before it was buried.

During the Millennium War, the biggest battle in Donglin turned out to be a water battle, which even Li Jing did not expect.

The white salt accumulated at the bottom of the lake was like snow, covering the wreckage of the human battle armor and the king's army that could not be seen at a glance.

Most of the surviving human battle armors have the obvious characteristics of water battle armors. The mutilated limbs of the king's legion that fell nearby were half buried in the snow salt, as huge as ancient sea beasts.Mu Yun passed through the belly of an iron walrus, and his footsteps stirred up the remaining water between the steel ribs, reflecting the searchlight spots on the knight's armor, echoing in the silent darkness.

Mu Yun stopped.Li Jing, who was walking in front of him, had turned into a small spot of light, and Zheng Quan came up from behind him, "You don't have to be so frightened," he said with a smile, "Look at this iron walrus, you can tell that the King's Legion is on the way." The entire army was wiped out in this battle, so there is no need to worry about the remaining large mechanical creatures operating here."

Mu Yun shook his head and continued to walk forward.The absolute silence around him gave him a bad feeling, as if something was watching them from the dark.He looked up again at the disemboweled stomach of the iron walrus. This was the fourth mechanical creature they saw that was based on an ancient sea beast. Cut in half.

He stopped again.He saw the two human battle armors that fell around the iron walrus. Their tonnage was close to forty tons, and their size was only half the size of the iron walrus.Mu Yun's eyes swept over the weapons they used, and saw the cannons distributed on the fuselage and the exposed damaged barrels. These two are water combat armor mainly equipped with torpedo missiles. The weapon in it has disappeared, but judging from the size and ratio of the slot, it is definitely not a large weapon that can split the iron walrus with a single knife.

However, the battle damage marks on the fuselages of these two battle armors looked like they were left by some kind of large weapon.Mu Yun raised his head, and stretched out his hand to caress the smooth fracture of the barrel.What kind of large weapon can cut through a machine gun of a forty-ton battle armor with one blow?His eyes scoured the vicinity, but found nothing.

The confusion felt in the castle of death rose again in Mu Yun's heart, he glanced at Zheng Quan, his right hand was still habitually placed on the hilt of his sword, even so, he shuttled through the high and low The figure remains in perfect balance between the huge wreckage. "Don't you think there's anything wrong here?" Mu Yun asked, "These two battle armors and this iron walrus don't look like they died together in the battle, they seemed to be killed by the same weapon of."

"Well, Zheng has indeed seen some kind of vague hints in some fragments. In fact, in the Millennium War, many human knights joined the king's army and fought side by side with mechanical creatures. This shameful betrayal is theirs. To bury the real reason of the ancient battlefield, it's a pity that the data damage of those fragmented chips is too serious, and Zheng can only recode and interpret the general meaning." Zheng Quan's voice came from the headset, Mu Yun Looking up, the figure belonging to Zheng Quan was shrouded in the silver-white light from the knight's armor. He seemed to be jumping between the wreckage of two armors and climbing to a higher place.

Mu Yun lowered his head, he was stepping on the cockpit door of a battle armor.The armor was almost completely buried by the snow salt at the bottom of the lake.Mu Yun rubbed away the white particles on the cockpit door with his hands, and tried to pull the door, and after a few harsh metal twisting sounds, the door opened in response.A figure in silver-white knight armor suddenly appeared in front of Mu Yun's eyes. He was so startled that he staggered back a step before realizing that it was his own reflection reflected by the stagnant water in the cockpit.

There are no corpses in the stagnant water, just like the armor in the dead castle, there is only an incomplete knight armor in the cockpit.

At this moment, he heard Zheng Quan's greeting coming from the headset.He raised his head and looked into the distance, and found an upright human battle armor that was half buried in the salt snow. Zheng Quan did not know when he climbed to the top of the battle armor, apparently from his angle, What did you see.

Mu Yun walked towards the armor, and it took him a few minutes to climb onto the shoulder of the armor. He looked down, and couldn't help gasping——

The confusion he had just now was not an illusion. Those human knights and the King's Legion were indeed fighting side by side. in the same direction.

In that direction, there is a huge and incomparably rectangular object, which is white because it is covered with thick snow salt at the bottom of the lake, faintly revealing the silhouettes of high and low scattered pavilions.At the end where the searchlight of the knight's armor shines, there is a huge monster that is almost completely shrouded in shadow. In the Hall of Valor, the object they saw above the water at the moment before the last ray of artificial sunlight disappeared was that top of things.

Mu Yun blinked, and it took him a second or two to realize that what he saw was a city.

In the center of this underground lake, there is actually a city.

Could it be that the treasure guarded by Princess Youming in the dark river is this city?
Why did these human knights and king legions attack this city at any cost?

Mu Yun desperately opened his eyes wide, but unfortunately the searchlights on the knight armor were limited in intensity. No matter how wide he opened his eyes, he could only see that the layout of the city was a multi-inlaid back-shaped structure, and the four corners of each back-shaped shape stood Surrounded by towering tower-like pavilions with cornices, the one that sits in the center of the back shape is the huge monster as tall as a mountain peak.As for the location of this city, what does it have to do with Jiuge, why did people build such a city in the lake at that time? Thinking about the clue, he only felt that the appearance of this city here gave him an indescribably strange feeling, but he couldn't say what it was that made him feel wrong.

Just as Mu Yun was about to turn her head to ask Zheng Quan what the scholar had to say, he saw that Zheng Quan had already taken off his knight mask at some point, and took out his usual pair of glasses, putting them on and taking them off for a while, tossing the old man After a long time, he finally shook his head and said in disbelief, "Strange, why can't you see clearly?"

"With your eyes, it's normal that you can't see clearly, right?" Mu Yun blatantly complained this time, thinking that even with my sharp eyes, I can only make out a city under this limited light source. How much do you want to see clearly with glasses?
"Hehe, do you think that guy is wearing glasses because his eyesight is bad?" Mu Yun couldn't help being startled when he heard Li Jing's voice suddenly. He turned around and found that Li Jing had also climbed up at some time and was sitting there. On a broken arm with a broken battle armor, the leg was swaying lazily, and a cigarette was lit in his hand.

It's not because of bad eyesight, is it to pretend to be gentle?Mu Yun scratched his head.He knew that the technology of improving eyesight by implanting artificial lenses on this continent is very mature. Glasses are an arty facial decoration for most people. The most common use is to install an eyeball on them. The tasteless function of the operation interface of the control does not have much practical value.However, there are always a small number of people who cannot be implanted with artificial lenses due to congenital conditions, and must use external means to correct their vision, but this situation is extremely rare among knights.Seeing that Zheng Quan wore glasses whenever he was not operating the armor, Mu Yun thought that he read too much and hurt his eyes, but he didn't expect that this guy only wore glasses for the sake of his beauty, so he took off his glasses just now. Put it on, what the hell are you doing?

Li Jing gave him a look of "I know you want to go wrong", raised his head and said to Zheng Quan: "Actually, this is not something worth keeping secret, can you tell me, scholar?"

"Is it worth keeping secrets that can be used to save lives at critical times?" Zheng Quan said angrily.He really didn't want to reveal the secret of this pair of glasses, but when he thought about the situation in front of him, if he didn't tell, maybe some people would not realize the danger of this ghost town in front of him, so he finally sighed and handed the glasses to Mu. Yun said, "This is the Yin-Yang eye."

Hearing the words "yin and yang eyes", Mu Yun's hand that took over the glasses immediately trembled, causing Zheng Quan's heart to tremble as well, and the muscles on his face also twitched a few times.At any rate, Mu Yun still held it tremblingly so that the glasses did not fall directly to the ground, and asked with a trembling voice, "This, this is the legendary high-dimensional space-time imager?"

Regarding the legendary "Yin-Yang Eye", the so-called high-dimensional space-time imager, Mu Yun had heard Mu Chuan mention it when he was in Baima City. Like Su Sheng's prosthetic body, Yin-Yang Eye is also a masterpiece of a puppeteer.It is said that for so many years, there have been no more than ten pairs of yin and yang eyes on the entire continent. Until now, people can only speculate that the basic principle is to use laser pulses to trigger rotational echoes for photon imaging. Since rotational echoes are a kind of The echo signal is intertwined with space and time, so its imaging result is close to the result of observing low-dimensional space from high-dimensional space, and the entire space can be captured in an instant without any detail—in simple terms, even Mu Yun Standing in front of Zheng Quan at this moment, he can also see the back of Zheng Quan's head through this pair of glasses, and he can even see Zheng Quan's actions one second before and one second after that at the same time.

"That's right, these are the yin and yang eyes made by the puppet master himself. It was given to Zheng by Zheng's master." Zheng Quan also wanted to speak calmly, but seeing Mu Yun holding those glasses, it might be possible at any time. A shaking hand smashed such precious yin and yang eyes, Zheng Quan couldn't calm down at all: he didn't say that although the yin and yang eyes were given to him by his master for the sake of face, he never said it was a gift. It was given to him, but he had to send it back in person after he had completed the task he was entrusted with. If it was accidentally damaged, he didn't know what to pay for it!

"Oh? I thought this pair of yin and yang eyes was a family heirloom of your Zheng family." Hearing Zheng Quan's words, Li Jing gave him a meaningful look.But Mu Yun didn't respond, he didn't have any interest in where the yin and yang eyes came from, and he didn't even care about Zheng Quan's apprenticeship.He just wants to see with his own eyes how it feels to look down from a high-dimensional space to a low-dimensional space!

This is a sharp weapon for cheating!It's no wonder that Zheng Quan's sword is so fast - you can see all the enemy's actions before and after, can this sword not be fast?Mu Yun despised Zheng Quan's Kuaijian for being opened and hung in his heart, and put his glasses on the bridge of his nose with both hands——

In the next second, Mu Yun immediately took off his glasses.Not to mention how weird the imaging result of looking down from the high-dimensional space to the low-dimensional space is, the fact that the brain receives so many visual signal shocks at the same time in an instant is enough to make people dizzy and nauseated.Fortunately, Zheng Quan has been watching Mu Yun from the sidelines, and immediately grabbed him when he saw Mu Yun's body swaying, otherwise it would be a small matter for Mu Yun to fall, and it would be a big trouble if the precious yin and yang eyes fell with him .

"You've been wearing this thing all the time, it's so perverted..." Mu Yun swallowed a mouthful of nauseated acid water, and returned the glasses to Zheng Quan, thinking that it's no wonder Zheng Quan never wore them when operating the armor Glasses, this thing is enough for observation. If you still wear this thing in battle, it is not a weapon, but a trick for yourself!

"Zheng is used to it." Zheng Quan breathed a sigh of relief after taking the glasses back in his hand.This sentence was very calm. What he didn't say was that the yin and yang eyes actually had a control switch. As long as he didn't turn on the pulse switch, this thing was just a pair of plain glasses.As for him not wearing this pair of glasses in battle, it was simply because he was afraid that he would not be able to pay for it if he broke it.

Seeing Mu Yun's admiration look as expected, Zheng Quan felt secretly proud, thinking that this kid is really easy to deceive, and that fox Li Jing would never be able to fall for such a trick.

"It's just that, isn't the yin and yang eye working perfectly?" After Mu Yun finished admiring it, he couldn't understand why Zheng Quan would wear glasses and say he couldn't see clearly. Mu Yun felt that he could see clearly, and it was It's too clear.

Zheng Quan sighed, and handed the glasses to Mu Yun reluctantly, "You should take another good look."

This time Mu Yun didn't take off his glasses immediately after putting them on, but took another serious look while enduring the pain of dizziness.

With just one glance, a layer of cold sweat broke out all over Mu Yun's body.

Because he saw every detail of the underground lake space through this pair of glasses, and even saw himself, Zheng Quan, and Li Jing, but he forcibly did not see the city.

Among all the unbearably complicated and clear details, only the location of the city is a black hole with nothing, as if the city does not exist at all in terms of time and space!
Damn it... Mu Yun took off his glasses, and the city in the darkness was right in front of his eyes. Although the outline of the city seemed blurred as if it was about to merge into the darkness, it did exist.

But when he put on the glasses again, the city disappeared again.

He finally understood what Zheng Quan's previous actions were all about.

But he didn't understand what was going on with this city—is it real, or just another illusion?
Zheng Quan took back his glasses and asked Li Jing, "Do you want to take a look?"

Li Jing shook his head, "No need, I have roughly understood what's going on."

He asked Zheng Quan: "Photon imaging?"

Zheng Quan nodded, thinking that Jiang is still old and hot, and the fox is indeed a fox, so he guessed what was going on right away.

Seeing that Mu Yun still looked confused, Li Jing reminded: "Photons are also carriers of electromagnetic radiation."

That's it!

Mu Yun immediately reacted: You must know that the three of them had to turn on the searchlights on the knight's armor now, and made themselves like three living targets in the darkness, because since they entered the ground, their knights The night vision mode equipped with the armor has never been able to start normally.

The night vision mode of the knight armor relies on the imaging of electromagnetic radiation thermal energy on the surface of objects, which is easily disturbed by temperature and magnetic fields.At this moment, Zheng Quan had already deciphered the mechanism code in the Hall of Valor, and turned off the magnetic field here. It stands to reason that the night vision mode should be able to resume normal work, but Mu Yun and the others tried several times, and the night vision mode in the three knight armors still remained. If it cannot be started, they can only speculate that it is because the geothermal eruption temperature in the dark river is extremely high, and the imaging element of the night vision mode has been damaged when passing through the dark river, which makes it unusable.

But Zheng Quan's yin and yang eyes rely on photon imaging, which will be disturbed by magnetic fields, but will never be disturbed by temperature. Moreover, Zheng Quan has kept this pair of glasses close to his body, and Mu Yun could see them clearly when he used them before. Looking at all the details except the city, it shows that the function of the glasses itself has not been damaged in the slightest.

Then there is only one explanation for not being able to see the city from the imaging results of this pair of yin and yang eyes.

In this city, there is a strong magnetic field interference.

In other words, in this city, there is a third large institution that is the same as the first two Halls of Valor.

And that means...

"It seems that Jiuge is in this ghost town," Zheng Quan said, "I thought we could use the Yin-Yang eye to locate it directly, but now we can't even see the way, so we just touch it like this. Afraid of getting caught."

"Well," Li Jing said, "yin and yang eyes don't work, so we can only rely on the naked eye. Fortunately, we were prepared."

"Isn't it?" Mu Yun looked at the actions of these two people, "Is it really necessary to make such a big commotion?"

"Don't worry," Li Jing comforted him while lowering his head to check the flare launcher, "We have searchlights on all the way, if there is an ambush here, our position would have been exposed long ago."

I'm even more worried if you say that!Mu Yun nervously glanced at the city immersed in darkness, thinking that the three of them were like three live targets with the searchlights shining brightly. I already have the urge to commit a crime, and at this time another flare is fired, isn't that the rhythm of firing at me?This is blatantly inviting others to commit crimes!

"Don't worry," Zheng Quan also said with a smile, "Even if this city is not for living people, we can't design the mechanism to be triggered by optical signals, otherwise we would have been recruited long ago. "

What do you mean this city is not for the living?It's not for the living, is it for the dead?Mu Yun heard Zheng Quan's words, and the more she listened, the more her heart became more and more frightened, but she saw Li Jing looked up at Zheng Quan, and said, "You have already seen it?"

"Well," Zheng Quan pushed his glasses, "Zheng only knows that there is only one kind of city in this world, which will be specially built at the bottom of an underground lake, guarded by You Ming Ji and multi-layered organs, and its location is even better. It is extremely confidential, and will not leave a single bit of record in any historical materials."

Mu Yun frowned, feeling that these two people were bullying her for not reading enough, "What are you guys talking about? Why haven't I seen anything yet?"

"Hehe, then you should keep your eyes open!"

Following Li Jing's greeting, the two flares lifted into the sky at the same time, and Mu Yun felt a sudden light in front of his eyes. The burning light instantly swayed down from the midair and landed on the top of this mysterious city, illuminating the area that was originally hidden. Shadows in the dark—

Those were countless ancient battle armors with a huge tonnage!
In the city at the bottom of this underground lake, there are actually arrays of phalanxes composed of battle armors one after another!
Taking the two diagonal lines of the back shape as the axis, the neatly arranged huge battle armor is like the wings of a giant dragon, extending down from the high platform in the center of the back shape. There are four square formations on the left and right wings. In front of the high platform, is a single centered square matrix.

The snow salt at the bottom of the lake is like white snow covering the ancient battle armor, covering their original metallic luster, and the bright paint on the fuselage has long been dim and mottled, but the solemn and majestic posture still makes people feel a sense of power. The stock is like the chilling meaning condensed in time and space!

Surrounding the battle formation, the beautifully carved monuments have long since decayed. The towering stone pillars correspond to each battle armor phalanx. Huge stone slabs hang down, carefully carved into the shape of knight flags. The patterns engraved on the stone slabs are the same as The knight's coat of arms is still clearly visible, marking the knight status in each phalanx and each armor.

In the scorching white light of the slowly descending flares, Mu Yun recognized the flag pattern on the front left battle armor phalanx. It was a young woman holding a sharp sword, and she was stepping on a blooming lotus. , surrounded by laughing children.

The image of that young woman was exactly Shao Siming in the Nine Songs he had seen on the giant pillar of the Hall of Valor.

On the opposite side of the phalanx, the patterns appearing at intervals on the slate flags are the Commander of the Nine Songs.

Mu Yun looked at everything in front of him in shock, and he recognized that behind the banners of the Shao Commander and the Grand Commander, the two phalanxes with the characteristics of amphibious battle armor belonged to the Hunan Army in Jiuge. Jun and Mrs. Xiang.Behind them, above the phalanx formed by huge battle armor like a fixed fort, hangs the banner of Dongjun who bowed his bow and shot Greedy Wolf in Nine Songs.Below the banner of Yun Zhongjun parallel to it is a square formation composed of Yanshi type armor.The two phalanxes at the end hang the patterns of Hebo and Shangui in Jiuge respectively, and their battle armors also have distinct characteristics of water battle armor and mountain battle armor.

In front of all the phalanxes is the formation of the Eastern Emperor Taiyi, which is composed of one hundred warrior armors with a tonnage of more than forty tons.Each battle armor stands proudly with a battle spear in its hand, and behind it are two huge crossed battle axes. Under the snow-covered snow salt that covers the fuselage like white snow, the gorgeous golden decorations of the past are still faintly visible.

This is an army, Mu Yun thought in shock, an army composed of nine legions, each legion is composed of different types of armor, and each legion can fight independently in different environments. When these nine legions are united, they are powerful enough to dominate any battlefield.

Everyone thinks that Jiuge is the Jiutai God Armor, even it is recorded in "Knight's Travel Record". No one would think that the real Jiuge is the Nine Legion.

A knight order capable of dominating the entire continent thousands of years ago.

Why was such a large army buried in an underground lake?

No one answered his question. It seemed that even Li Jing and Zheng Quan were shocked by the scene before them. Everyone held their breath and stared at this army that had been sleeping for thousands of years.As the height of the flares slowly decreased, the battle armor phalanx standing silently at the bottom of the lake disappeared into the darkness again, the light of the flares became dimmer, and the last burning beam fell on the high platform.

There is something there.On the central axis of all the battle armor phalanxes, at the position originally blocked by the shadow cast by the towering mountain in the center of the city, it is there——

Mu Yun turned on the optical long-distance observation mode in the knight's mask, and then took a deep breath.

On that high platform surrounded by a phalanx formed by countless battle armors, there was actually a person.
