Sky Dragon Rider

"Woo!~~~"

Through the hexagonal double-glazed glass, a loud and long roar came in.

The thick stone strips and the standard steel skeleton seemed to be floating by invisible big hands, and they flew continuously into the underground passage whose walls were rammed and reinforced by earth magic.

"Can we go down?"

Sita Mayas once again looked at the entrance of the tunnel that had just been dug through. The stone steps were paved one after another, and the cave wall was supported by a steel structure. Just a black feather star can withstand countless human beings.

If not, Qi Fei and Lin Mo would not choose to make the underground passage project so comprehensive and meticulous.

"Okay! Be more careful! If it's convenient, please help me remove all dangerous creatures I encounter."

Lin Mo nodded, and officially fulfilled his promise to let the three gold dragons enter the underground world through the passage to start their journey of seeking revenge.

The gold-type dragons are really vengeful dragons. Xita Mayas beat up the whole family, knocked out all the voices of opposition, and forcibly ascended to the position of patriarch, and launched revenge actions not long after.

In return for digging and clearing the passage, Lin Mo asked the gold coins to hand over some of the technology trees brought back from the earth's technological civilization to the three gold dragons in the form of "fire seeds" as a security guarantee after going deep into the underground world .

"Thank you for the gift, I like it very much! Then leave it to us!"

The female golden dragon Sita Mayas nodded, and palm-sized white lights lit up on the top of her head, neck, limbs, dragon wings, lower abdomen, back and dragon tail, and her learning progress was very fast. Has fully grasped the evolution of light bulbs.

Whether it is an ordinary light source.Or laser, according to the level of science and technology on the earth, it can only be regarded as a superficial technology at the elementary school level (the technology born 50 years ago in the civilization of the earth), and the biggest technical obstacle lies in the application of materials.For the gold dragon family, such difficulty does not exist at all.

The SEG unit evolved and formed in the body continuously provided a steady current, so that the incandescent lights on the three golden dragons illuminated a channel with a diameter of about 20 meters, and the three blazing beams went straight to the deeper depths.After a while, their figures quickly disappeared into the passage.

Boom! ~~Boom! ~~Boom......

Suddenly, there were strange muffled sounds like drumbeats on Lin Mo's body.

The sound wave detection system is rapidly building a three-dimensional channel geological model on the transparent mask display screen inside the "Dragon General" tactical helmet through the echo.

Sita Mayas is only considered to eliminate potentially dangerous creatures, not a formal survey, so he needs to make all preparations.

Stone and steel materials were still continuously conveyed into the passage, and under the control of Xuanyuhuangxing Leiwen's powerful spiritual power, steps and supports were quickly built.Although there is some interference to the sound wave detection, it will not affect the final detection result.

"There is still a hollow structure at a depth of fifteen kilometers. There should be an [-]% chance that this passage will connect to the underground world!"

Standing at the entrance of the passage, Lin Mo raised his head and waved to Modai, Qi Fei and Tania in the observation room on the second floor not far away. Through the ubiquitous WIFI environment inside the steel structure building, his voice easily Passed into the ears of three young women.

The hall at the entrance is located in the center of the steel structure building, reaching the fourth floor inside.The room where the observation channel can be opened is located in the raised part inside the ring, and will become an important place for command and monitoring functions in the future.

In the room with an excellent view, six 42-inch large screens are displaying different information transmitted by the "Dragon General" tactical armor, one of which is impressively displaying the interior model of the passage just detected, although it is only a part of it, it looks Already amazing.

"Lord Mo Lin, you must be careful, if you encounter danger, you must withdraw immediately!"

Even though there were three gold-type dragons standing in front, Her Royal Highness Princess Regent Maudai still cared about the safety of the dragon knight.

Plus gold coins.Four golden dragons plus a dragon knight.To carry out the operation of opening up the connection between the underground world and the surface world, such a luxurious lineup can be called an unprecedented large-scale effort.

"Don't force it! Not making money is a trivial matter, don't risk your life!"

In Qi Fei's view, this stupid and stupid wood is the greatest wealth he has in his life.She is also mentally prepared to eventually abandon this passage, and some property will be lost.Compared with Lin Mo's safety, it's not worth mentioning at all.

However, she was unexpectedly assisted by three golden dragons, which made her more confident.

"Gold coins! It's our turn to go down! Sita Mayas and they seem to be going well."

Lin Mo touched the space-type alchemy memory full of supplies on his right wrist, and greeted the gold-type dragon on standby.

This is just a preliminary exploration, and there are three gold-type giant dragons taking the initiative to "walk the thunder" in front, so the possibility of him encountering danger is very low.

"Uncle Long lost a lot today, you must make it up to me later!"

Reluctantly paying three "fire seeds", the golden dragon grunted, and more than ten light spots lit up on one side of its body. The lighting source it evolved was more advanced than the incandescent light bulbs of Sita Mayas and the others. Some, semiconductor light-emitting technology has lower power consumption and higher brightness.

"Isn't it just some coins, you will be famous for it forever, and you didn't eat less back then, it's okay to take out a little bit, now you still need to worry about starvation? Don't tell me those worthless things!"

Lin Mo shook his head, this foodie was pretending again.

Although the coin gold contained in each "fire seed" is only as big as a matchbox, if it is used to evolve semiconductor components, it is enough to easily arm an adult gold-type dragon. The coin gold content required by an ordinary central processing unit, At the level of nano-processing, it is only as big as ordinary sand grains.

"Stingy!"

The country is easy to change, but the nature is hard to change. The gold dragon gold coin of the gold department got into the entrance of the passage angrily.

"I still keep the metals I brought back from the barbarian territory. As long as I connect to the underground world, I may be able to taste more delicious rare metals. The mineral resources there are richer. It may not take long. You will be interested in black steel and Mithril is greasy, just like now, if I give you black iron, you probably won’t be able to eat it anymore, right?"

Bad temper for gold coins.Lin Mo, who is well-mannered, whetted his appetite with a few casual words.

"Bah, bah, don't mention black iron to Mr. Long. Is that stuff full of scum for dragons to eat? I have the appetite. I might as well eat wood."

It is easy to go from simple to extravagant, and difficult to go from extravagant to simple. If a gold dragon who is used to eating mid-to-high-end metals is allowed to gnaw on those inferior and inferior iron materials, I am afraid that he even has the heart to die. How to take those black irons as rations contentedly.

Now if it is forcefully forced to feed itself with black iron generals, I am afraid it would rather break up its own dragon knight and let everyone fight together to die together.

Everything else can be tolerated, but eating is absolutely unbearable.

"Work and work. The more you work, the more you get. If you don't work, you won't have food!"

Lin Mo laughed, and casually threw two sets of huge spools as tall as a person onto the back of the golden dragon. While pulling the thread as thick as a finger, he went to the left wall and ceiling of the cave, and fixed it through the pre-designed The module holds those two thick wires of different colors together.

The sheathed black wire laid on the roof of the cave is a three-core wire, which leads to a screw lamp holder through the power connection module every five steps.Screw on a 3-watt LED bulb the size of an egg.

Although the light was dim, it was enough to illuminate this gradually deepening passage.

The other white wire is an eight-core shielded Cat[-]e wire, which is used to establish a physical communication connection. Like the power supply wire, it uses the natural superconducting material of willow willow, but it is mechanically twisted after re-spinning through chemistry and alchemy. The composite wire core has a much larger diameter and strength.

As a long-distance digital communication carrier, optical fiber was originally a very suitable choice, but compared with the superconducting wire core, it immediately became useless.

Although the optical fiber has a low signal loss rate, it is not a superconductor after all.And the connection requirements are high.The relay equipment is also relatively complicated. It is as simple as pinching the crystal head and plugging in a wireless relay switch.

There is one light socket every five steps, and one CAT1E data line node is one kilometer.Not only a wireless relay switch, but also a WIFI hotspot.It just happens that the signal can be seamlessly connected.

In addition, there is a high-definition camera 5 kilometers away, which can monitor the situation in the channel at any time.

As Lin Mo and the gold coins continued to deepen, the underground passage was no longer dark, but gradually filled with light.

"Now it is 6 kilometers from the ground, the passage is 31 kilometers long, the air humidity is 70%, and the oxygen content is normal. If there is no mistake, the gold coin and I should be able to reach the underground world."

Through a wireless relay switch that was just activated, Lin Mo's voice was clearly transmitted to the room on the second floor built with steel glass curtain walls on the ground.

Along the way, he encountered seventeen forked passages, and a natural stone hall of about 3000 square meters, which was naturally formed for an unknown number of years, was very dry, and there were no traces of animals and plants, which could be used as a buffer and rest Space.

"Have you encountered any creatures?"

Qi Fei and the others had already sat down, and their gazes were fixed on the display screens that were divided into two rows. The first screen was continuously connected to the images captured by the new cameras, and the second screen displayed the constantly accurate and perfected images. Channel model, the third screen constantly refreshes data such as air and depth, the fourth screen monitors voltage and network environment, the fifth screen keeps in sync with the optical camera of the "Dragon General" tactical helmet, and the sixth screen is still black standby.

"No, there are only some fungi and glowing moss, no large creatures. The monsters that fled in at the beginning should have left. I didn't see their bodies. Sita Mayas and they are still moving forward. The paw prints on the ground are very clear, Raven My mental power can no longer go any deeper. I suggest that the five Ferrero monsters stationed in the tunnel of the Ice Rock Mountain be transferred over to help strengthen the passage. Those who come behind should be careful not to leave me on the ground with wires and network cables, etc. Equipment trampled.

Standing on the back of the golden dragon, Lin Mo continued to throw out black and white cables of two different colors to the side of the passage.

"Okay! I'll arrange it now!"

The Regent Princess Modai nodded. The entire territory of Portland has been occupied by the Slans. The tunnel through the Ice Rock Mountains no longer needs so many guards, but the power of the five monsters can be borrowed to further build this tunnel. The passage to the underground world.

"Squeak!~"

Suddenly, there was a vague roar from the depths of the passage.

"What's the sound? Did you hear it?"

In the room on the ground, Qi Feiteng got up and looked at each other with Modai and Tania.

"I heard it too!"

The regent princess Maode stood up slowly, nodded vigorously, with a very dignified expression.

"Me too!" Tanya followed up to confirm this.

The strange sound that suddenly sounded came from the six display screens hanging on the stainless steel frame. If you guessed correctly, it should be the sound collected by the "Dragon General" tactical armor, which was transmitted to the computer through network cables and wireless relay switches. ground.

"Mu Mu, is something wrong down here!"

Qi Fei, who had been worrying about Lin Mo's safety, just felt relieved, but she didn't expect the accident to happen.

"It seems so. It should be far away from the sound, but there is nothing to worry about. The fighting power of the three gold dragons is enough to wipe out all threats. Even if they cannot be defeated, they can escape. At least I can escape first." step."

Lin Mo did not intend to stop the gold coins, but chose to continue to go deep into the wiring.

Going forward for about 10 kilometers, the passage turns into a very vast space, with stalagmites and pillars everywhere, and the terrain is very strange.

Through another sound wave detection, the horizontal area of ​​this space is at least a dozen square kilometers, and there is a circular lake in the center, which looks like a small almost closed world.

The closer you get to the water source, you can see more and more fluorescent plants unique to the underground world, such as fungi, moss lichens, and low and weak grass plants, where some arthropod insects and molluscs live and reproduce.

Lin Mo didn't see Sita Mayas and the other two golden dragons, but he found the bodies of two crustal creatures near another passage on the other side of the lake.

Although some are fragmented and horrible, it is still possible to tell that they are monsters with blue blood.

"It's them?!"

Lin Mo was stunned, the two monsters whose bodies were almost torn apart turned out to be his old acquaintances.

On the way back to the imperial capital, I temporarily accepted the commission of Baron Taiman, the lord of Yangshui City, to destroy the monsters that came up from the underground world to harm the place. They met again here, but they had turned into two corpses.

This space may be their territory, but it's just bad luck, and they encountered three golden dragons who ruled all kinds of dissatisfaction.

Sita Mayas kept her promise and killed these two hidden dangers for Lin Mo.

"Is it a monster?"

Qi Fei stared at the fifth screen and exclaimed. What Lin Mo saw, she and others could also see.

For the three young women, the shot does look a bit scary.
