Alien Relic Hunter.

Chapter 633 Silent
"The airship can no longer get closer, and if it goes any further, it will be shot down by those anti-aircraft lasers." The frigate captain's voice came from the loudspeaker, "There have been warships that have tried it before. , even the shields of heavy cruisers can't stop those lasers, I can only send you here."

"Everyone, check your equipment for the last time and prepare for airborne!" The commander of the mobile unit stood up from his seat and shouted to his subordinates.

The clang of metal and iron resounded in the cabin, and after a while, the entire army was ready for battle.

And the hatch at the bottom of the cargo hold has also been slowly opened—the "Cross Pick" has lowered the suspension height to 160 meters. Except for the armored vehicles that need to use steel cables to assist in landing, the other mechas and those wearing power armor The soldiers jumped out of the hatch directly, relying on the buffer of their own propellers, and fell steadily to the ground.

"Good luck to everyone." The frigate captain's voice sounded in the communication channel for the last time, and then the "Cross Pick" quickly rose to an altitude of more than a thousand meters, joining the array that bombarded the core control tower.

"If you walk 50 meters forward, you will enter the core control area." The commander of the mobile unit pointed to the "metal forest" consisting of buildings with an average height of 200 meters in front of him, and said to Ke Lan.

The core control area of ​​the Bronze City ruins is the "fourth ring" located in the center of the inner ring. This fourth ring is different from the first three rings, and has no obvious regional boundaries-before the operation began, the core control area was only It's just a general concept. Basically, as long as it is related to the relic control center, it can be counted in the core control area.But after the operation started, the participating troops quickly drew up a specific area.

The border of the so-called core control area is actually the no-fly zone of the air force fleet. Any aircraft that enters this area will be instantly destroyed by powerful laser weapons. There are several wrecks of warships scattered in the outer area... ranging from heavy cruisers with heavy armor and strong shields to high-speed assault ships that are extremely fast and difficult to lock. As for the wrecks of fighter jets and flying mechs, there are countless.

On the contrary, it enters from the ground and will not be attacked by these laser weapons.

Two "Shield Mountain" mechas walked in the front carrying a composite solid shield weighing [-] tons, while the others followed silently. The atmosphere in this mobile unit was very depressing. Every soldier's nerves are very tense... In contrast, Ke Lan and the others are in a much better situation, and that guy Layton is even bragging on the team channel: "What's the scene? Haven't you seen it? Just trying to scare me with such a small battle, I really underestimated my courage."

"But you look nervous." Valentina, who doesn't like talking very much, suddenly interjected.

"Eh? How come? Sister Xiaona, don't talk nonsense, why am I nervous? It doesn't exist at all." Layton immediately denied.

"But I found that Augustus's energy shield generator has been in a critical state." Valentina said sharply.

The "critical state" of the energy shield generator refers to controlling the charging efficiency within the threshold of 99.95%~99.99%. The shield generator in the critical state, at least injecting a little more energy, can The shield is activated immediately, and at the moment of activation, the power of the shield itself is directly pulled to the maximum.

Of course, the critical state will also cause a lot of damage to the shield generator itself... This is like a rubber band, which is in a tight state for a long time, and will definitely lose its elasticity or simply break in the end.A shield generator that is in a critical state for a long time will inevitably affect the life of the machine. Therefore, even in a combat state, the charging efficiency of the energy shield will only be maintained below 50.00%. Extends the lifespan of shield generators.

Like the shield generator on the Augustus body, it only takes about 50.00 seconds to charge from 0.3% to [-]%. Unless it is in a close-to-hand combat situation, the operation manual rarely recommends the driver Keeps shield generators in a critical state.

And some low-quality shield generators, or shield generators that have been severely damaged when dug out of the ruins, even have a high probability of self-explosion in a critical state... Like this kind of shield generator, It is absolutely forbidden to enter the critical state.

At this time, Layton stuck the shield generator in a critical state, which is enough to show how nervous his heart is.

"You... I, I'm not nervous here, I'm called being cautious, it's always right to be careful, right? Ke Lan, don't you think so?"

"It can be seen that you are very nervous just because you are full of nonsense." Ke Lan responded casually, "Actually, there is nothing to be ashamed of, I am also very nervous now, moderate nervousness can help improve reaction speed, which is a good thing. "

"But it's not good to be too nervous. Lao Lei, if you need it, I can provide you with some medicine." Ivan said, and he reached into his pocket and started to fumble.

"Medicine...there's no need for the medicine. If the old dog finds out about this, he will have to laugh at me for several years."

"Then I'll keep it for myself." Ivan groped for a long time, and finally found a stainless steel mini wine jug, unscrewed the lid, and took a sip with his head up.

"Fuck, this is the medicine you were talking about. Hurry up and give me a sip too." Layton yelled immediately.

"Forget it, drunk driving is illegal, not only driving, but also the mecha." Ivan said and put the hip flask back.

"Cut, cheapskate."

Although there was no substantive content in the topics of conversation between the few people, but after such a disturbance, the original nervousness disappeared a lot at this time.

"Layton, check the communication signal to see if you can still get in touch with the troops outside." Ke Lan patted Augustus' knee and said.

"I've been staring at it since I came in. The deeper you go into the core control area, the more serious the radio interference is... The source of the interference comes from these tall metal buildings—this means that there are no interference devices inside these buildings. There are hundreds of metal buildings standing here, which is enough to form a huge interference field." Layton said, "My communication signal has been cut off within 100 meters of coming in... I don't know about that 'Beidou' Is there still any signal, the power of the communication equipment of that thing is much greater."

"It's already broken." Valentina said, relying on the unique scanning system of the Blasphemer Mecha, she has been monitoring the status of these mechas in the team, "Your signal is entering the core control area It broke at 98 meters, and that Taipei Dou lasted 30 meters longer than you.”

"Tsk...the so-called high power is nothing more than that."

Not only for external communication, Ke Lan and the others were only a few meters apart, and the team's communication channel was already full of noisy electric sounds. 33 even took off the earphones directly and stuffed them into the backpack.

Now they have walked in for nearly 500 meters, even if the signal strength of the communication equipment is amplified ten times, they still cannot get in touch with the outside world - the core control area is a circular building complex, the further they go in, the surroundings can The more metal buildings are the source of interference, the more the interference intensity is increased geometrically... let alone radio communication now, even some sensitive monitoring equipment has begun to be affected, Ke Lan glanced at his wrist The magnetized north needle on the dial of the watch is spinning wildly, with no intention of stopping at all.

The entire core control area is a perfect circle with a diameter of six kilometers, and the central high tower is located on the center of the circle. If Ke Lan and the others do not deviate in their direction of travel, they can reach the high-rise area as long as they advance less than 500 meters. The bottom of the tower is up.

At this moment, Ke Lan stopped suddenly.

He grabbed the commander of the mobile unit beside him, and the latter was shocked immediately, and asked quickly, "Did you find anything unusual?"

"It's too quiet, don't you think?" Ke Lan said in a deep voice.

"Eh? What do you mean... We haven't encountered the enemy yet, isn't it normal to be quiet?" the commander asked puzzled.

"No, that's not what I meant. My teammates were still chatting just now, so I didn't notice something was wrong, but now, after they all shut up, I realized that I couldn't hear the voices of the front mechas at all. Footsteps."

"Footsteps?!" The commander was stunned for a moment, and immediately turned his head to look at the front of the team.

At the forefront are two "Shield Mountains". As heavy defensive mechs, the "Shield Mountains" do not have a sliding air cushion device in their footsteps. Movements must be completed by moving their legs and keeping their feet on the ground.

Counting the equipment, ammunition, spare fuel, and energy blocks, a fully equipped "Shield Mountain" weighs at least 25 tons. For a body of this tonnage, no matter how careful the steps are, it is impossible to make no sound at all— — What's more, the ground in the entire ancient bronze city ruins is covered with hard alloy floor tiles. If you step on this kind of ground, even special military boots with soft rubber soles cannot be completely silent.

But now, Ke Lan and the others couldn't hear the footsteps of the two "Shield Mountains" advancing.

They are only 50 meters away from the front of the line.

"What's going on here?" The commander frowned, "Why don't I tell him to stop—"

"No, don't let them stop just yet."

Ke Lan squatted down, put his palms on the ground, fixed his eyes on the two shield mountains in front, and said, "Let the two shield mountains continue to move forward, and everyone else and the machine body should not move."

The thick big feet of Dunshan fell slowly, and Ke Lan obviously felt a shock coming from the ground, but he didn't hear any sound.

Immediately afterwards, he lay down all over and put his ears on the ground, only then did he hear a dull "boom" coming from what seemed to be an extremely distant place.

"I kind of know why the six airborne troops in front of us didn't move at all after they came in, and the sound from this place couldn't get out at all," Ke Lan said.

"Can't transmit sound?" The commander subconsciously opened the mask of the power armor, took a deep breath, "But, but... this place is not a vacuum, and even the oxygen content in the air can fully meet the needs of human breathing ..."

"It doesn't matter if it's a vacuum or not." Ke Lan shook his head and said, "It should be a technological product of some kind of Alpha civilization, which blocked the transmission of sound."

He started to walk forward until he was within 20 meters of the Shield Mountain before the sound of heavy footsteps appeared in his ears.

He turned his head and saw that the commander seemed to be yelling towards him, but he could only see the movement of the other's mouth, but he couldn't hear the sound from his throat at all.

It's like a pantomime show.

Ke Lan walked back quickly again, and when he was within 20 meters of the commander, he heard the commander eagerly asking: "How is it, have you figured out what's going on?"

"Let the two shield mountains in front stop first, and don't go too far." Ke Lan said, "The information that has been obtained so far, the sound can only be transmitted to a distance of 20 meters from this place-this blocking method It is not gradually weakened, but has a clear 'boundary', and there is only one step between hearing and non-hearing. In addition, solids on the ground can transmit sound, but the transmitted sound will be distorted. And it's hard to tell distance and direction."

"The effective distance of radio communication is only about 40 meters, and the further we go in, the distance will become smaller. I guess, when we get to the bottom of the tower, even if we communicate face to face, we will not be able to hear what the other party is saying. Yes." Ke Lan continued, "But the good news is that vision does not seem to be affected, so we can use gestures to communicate with people far away, and in addition, wired communication methods will not be disturbed."

"I see, I'll let someone connect the vehicle and the airframe with a communication cable." The commander nodded and said, "But to be honest, even though the facts are right in front of me, I still feel a sense of unreality sense……"

"Looking good." Ke Lan didn't explain much, and directly took off a grenade hanging on the opponent's shoulder, pulled the ring, held it in his hand and counted silently for a few seconds, and then threw it diagonally upwards. go out--

The grenade exploded about 30 meters away from them and about ten meters above the ground. The commander who didn't close his mask could only feel a wave of air filled with the smell of gunpowder, but the sound of the grenade's explosion was astonishing. It seems to have disappeared out of thin air.

It's like when watching a 4D movie, the cinema simulates all the environmental effects such as body sensation, smell, smoke, etc., but the audio file, which is second only to the picture in importance, is missing.
