The legend of Tiga

Chapter 2090 Underground City
"A dungeon construction company in Aoba City?"

Daigu, who finally came out to work, looked at the windshield in front of him with some surprise. In addition to the navigation route, there was also Horii in a white coat.

Although the vehicle was moving, Dagu, who was sitting in the driver's seat, not only did not put his hands on the steering wheel, but even his feet were not on the accelerator or brake, but the vehicle still drove normally.

The autonomous driving developed based on TPC's smart butler Levitra has been applied to various fields of TPC. Except for fighter jets, most of TPC's mechanical vehicles widely use intelligent operating systems.

It was also the application of this system that, as soon as Dagu shouted out "Aoba City's Underground City Construction Company", the detailed information of this construction investment company immediately appeared on the screen, allowing Dagu to have a general understanding of this enterprise with just a glance.

The company lives up to its name!
What we do is build a dungeon, that is, build a city underground.

According to the company's public plan, their goal is to build a huge building complex underground that is no less than a city on the ground, to accommodate and live for tens of millions of people, thereby alleviating congestion on the ground.

Of course, this is obviously a big (bull) pie (B), but it is normal. It is a PPT for investors to see, so it must be a big deal.

If the target is 10 million, just ignore the ten thousand at the end, or remove the thousand at the beginning, then it will be almost true.

However, this project has received a lot of investment because of its novelty.

Because it is not an underground city with an underground street, but a city that is truly moved underground.

According to the company's first phase goal, three hemispherical cavities will be dug underground, the foundation will be compacted with high-grade concrete, and the vault will be made of a composite material that is several times stronger than steel, thus providing a stable underground space, and then buildings and roads will be built inside.

The vault will be covered with a large display screen to simulate the four seasons and the rising and setting of the sun and the moon. In the later stage, a simulated weather system with wind, rain and even snow will be added. Special lights will also enable plants to carry out normal photosynthesis. Therefore, flowers, plants and trees can be planted in the underground city to improve the physical and mental health of the residents.

These three blocks will provide living space for at least one thousand homes. They will be connected to each other by a subway system underground and by high-speed elevators on the ground. These twenty high-speed elevators are located in different places, so each household only needs thirty seconds to find an elevator to the ground and the subway.

"Amazing!"

Dagu was quite surprised after seeing the renderings provided by this company.

Building a city underground is such a grand plan.

The difficulty and cost of this are much higher than on the ground. After all, we have to consider earthquakes, water seepage, rocks and even magma. After all, this long and narrow island is located on the edge of the plate, with frequent earthquakes and numerous volcanoes. It is much more difficult to build underground than in other calm areas.

But no matter what, the courage to try is worthy of praise.

After all, you have to try it yourself to know whether the road is passable or the water is deep. If you just listen to what others say, you will never take a single step forward in your life.

"Yes, the president of this company is a man with a lot of ideas, and he's brave enough to put them into practice." Horii followed suit and praised, causing Daiko to ask, "Do you know him?"

"Yes," Horii nodded and said, "I saw him at the Science and Technology Exchange Conference. He developed an instrument that can release special vibration waves - PW waves. Yes, it is a kind of Doppler pulse wave. When it propagates underground, it can shatter the rocks in a certain area. Even the strongest granite will be pulverized. Then we just need to use a large vacuum cleaner to suck out the powder and the excavation is complete."

"This is even more powerful!" Dagu exclaimed. This is much more high-tech than blasting and tunnel boring machines, and it seems to be even faster.

"." Horii showed a very obvious speechless expression, and paused for a moment before saying: "The headquarters base in the mountains was dug using PW waves."

“It’s applied so early.”

Dagu was amazed again. The headquarters base was built six or seven years ago, and it was applied at that time, which was indeed quite early.

"It was because of the successful case of large-scale projects that Tachibana Masahiro decided to start his own business. He used his PW wave to participate in many projects. After accumulating some assets, he opened the Tachibana Company and started what he really wanted to do - building an underground city."

This time it was Dagu's turn to be silent, or rather to be shocked. People who have ideals and are willing to take action are always worthy of respect.

"So where are you going this time?" Dagu asked hesitantly. He was called out from home and traveled thousands of miles to Aoba City.

"PW waves may be able to be used to find the monster that burrowed underground." Horii is still obsessed with the monster that interrupted the GW-R experiment, and has been thinking about how to find this Sphia synthetic beast.

Then, while reading the literature, he accidentally caught a glimpse of the PW wave that was demonstrated at a scientific exchange conference on the New Field Project a long time ago. Horii suddenly had an idea and thought that this kind of wave that could hit a certain area like a laser beam could be used to find monsters underground.

Sound waves are the same as water waves. Once released, they will spread in all directions. Ultrasonic waves rely on the echoes after diffusion for positioning and detection.

But diffusion in the medium means loss, and when the range is large enough, the fluctuation will be extremely weak.

But if the waves are gathered and emitted in a direction like a laser, the propagation distance will be very long.

"Isn't there a new X-ray observation satellite installed?"

Dagu asked in confusion. TPC has launched many satellites. Even Dagu knew that in order to better observe the earth, TPC has launched more than one detection satellite that can take X-rays of the earth to better detect the underground.

There are so many satellites in the sky, aren’t they enough?

"Because the satellite's detection depth is limited, but for waves, ten thousand meters is too short." Horii had tried this method a long time ago. Under the most ideal circumstances, the detection depth is less than a thousand meters. If the terrain is complicated, it is only a mere two or three hundred meters, which is far worse than waves.

Just like earthquake waves, they can propagate hundreds or even thousands of kilometers away.

After Horii's explanation, Daigu understood what Horii wanted to do, which was to use this directional PW wave to find monsters underground.

After all, monsters, whether in terms of body density or other aspects, are different from underground rocks and minerals, and can be identified by the feedback of echoes.
