"Is this thing called a shield machine?" Yan Wu said suspiciously, looking at the huge guy in front of him that was close to five stories high.

The cross-section of this big thing in front of Yan Wu looks like a grinding disc, but this all-metal grinding disc is installed with eight groups of cutter heads arranged in a row, all of which are arranged in a radial shape, and the color of each group is different, so it is thought that it has different uses.

"1,500 tons, we like to call it the 'Underground Dragon'. An engineer wearing glasses stood next to Yan Wu and said proudly, "The shield machine is the scientific name, because from the cross-section, it looks like a round shield, so it is called a shield machine." However, in the Great Xia Dynasty, only the tunnel boring machine that hit the soft soil layer was called the shield machine, and this kind of rock formation we called it TBM, which is the underground dragon just mentioned. ”

"Why is its main body so long, but the cutter head is only the front part?" Yan Wu asked, pointing to the half-meter-thick disc cutter head and the cylindrical steel component tens of meters long behind it.

The engineer laughed, "The cutter head is for crushing rocks, so it's okay to be shorter." The main body length is also responsible for temporarily supporting the newly excavated tunnel, bearing the pressure of the surrounding soil layer, sometimes bearing the groundwater pressure, and keeping the groundwater out, and is also responsible for collecting the ground rocks and soil onto the conveyor belt and sending them out to the ground to avoid backlog at the front end. ”

"Our imperial court is so powerful now?" Yan Wu was taken aback, if he hadn't had the ability to come here, he wouldn't have been able to come into contact with this type of national heavy weapon. Now when the Great Xia Dynasty is secretly starting work, preparing to dig a tunnel of 1,000 kilometers in a short period of time to connect the northwest and the Qinghai-Tibet Plateau, countless heavy machinery of various types drove past Yan Wu, and he was stunned, it turned out that the Great Xia Dynasty that he lived in his life was so good?

Yan Wu also said that where did his previous tax payments go, it turned out that they were all spent on these things. Sure enough, it is a great thing for a physically weak human being to invent, produce, and manipulate such a huge device to revolutionize the surface and interior of the earth.

"How much does this thing cost?" Yan Wu patted the shell of the shield machine, and a cold chill came from his palm.

The engineer said, "It's worth 500 million Daxia coins." ”

Yan Wu was taken aback, "So expensive?" If he participated in the whole process and opened this thousand-kilometer tunnel, he would only be rewarded with a billion yuan, and the thing in front of him would be worth half of it, which was really expensive.

"It's not expensive. In order to build the Qinling Tunnel, we spent 350 million euros to import a shield machine from Germany. Today, this seems to be an astronomical amount. Even so, their service couldn't keep up at the time. Once there is a small illness or disaster, we will go crazy and will not repair it at all. The shutdown of a shield machine will bring a loss of nearly one million yuan per day. However, foreign experts work a strict eight-hour day, do not work overtime on weekends, and even start calculating their expenses from the moment they leave the house, and their wages for an hour can reach 600 to 800 euros. At this point, the engineer's eyes turned red.

After that, the imperial court summoned scientists and worked hard to study, which led to the continuous breakthroughs of the Great Xia Dynasty in this field. Now Daxia has produced more than 1,500 such machinery, and its share of the national market has reached 60%. And the dragon in front of us has broken the situation that foreign brands have dominated the world for many years. After all, the largest shield machine in the United States is now 17.32 meters in diameter, and the one in front of us has reached the specification of 15.03 meters. ”

"Does this thing cost fuel? How to calculate the cost?" Yan Wu is worthy of being an old driver, and when he sees such a large equipment, the first thing that comes to mind is fuel consumption, which is a disadvantage left by the two barrels of oil pits for many years.

The engineer was silent for a moment, "Mainly looking at the geology, this tunnel is dominated by alpine permafrost and rock, the geological structure is compact, the groundwater resources are complex, and there may be a karst cave environment left after the disappearance of the underground river, which is also a test for the life of the cutter head." However, the life of the EPB depends on the spindle, which ranges from 6 to 10 km. It is cumbersome, time-consuming and labor-intensive to replace. ”

"How about the speed, how many kilometers can you hit in a day?" Yan Wu asked according to his ability, without seeing the embarrassment on the engineer's face.

"The soft soil layer is a little faster, about 20 meters per day. Hard rock, less than 10 meters per day. And the cost is relatively high, every meter forward, it costs about 60,000 to 100,000 yuan. ”

"What?!This is so expensive?!And so slow?!" Yan Wu suddenly pointed to the most advanced shield machine of the Great Xia Dynasty and shouted, 20 meters a day, 50 days in a row for only one kilometer, this must be normal equipment, no problems. No wonder a group of bigwigs in the imperial court happily agreed to their request and gave a refreshing price of 1 million per kilometer. Compared with this equipment, the price of 60,000 yuan per meter is really a conscience price, and it is simply a big sale! At this rate, a thousand kilometers of tunnels will be played until the year of the monkey, no wonder the country's initial plan is 17 years, and I don't know how many shield machines will work together at the same time to achieve the planned progress.

Yan Wu only knew at this time that the hardships of the so-called imperial court project were really not capable of ordinary machinery, so it was up to them.

Yan Wu patted the engineer on the shoulder, "Big brother, it's really hard for you, for a project, you have to stay in the desert Gobi for a few years or even more than ten years, I really admire you." I couldn't stay even for three days. ”

The engineer smiled embarrassedly, wasn't this kind of thing a common thing for those of them who were dedicated to the Great Xia court?

At this moment, Ms. Fu, who was already on the side, came over wearing a field engineering suit, "Mr. Yan, do you think we can start?"

Yan Wu nodded, "I touched the shield machine just now, and I probably know its principle, so it should be no problem." You tell everybody to stand up a little bit, and I'll get to work. But remember, my salary is on a daily basis, and I don't pay it on credit!"

Ms. Fu smiled, "No problem, the bank has prepared the money, just waiting for Mr. Yan to do it." ”

Yan Wu nodded, "I'll try fifty meters first." You send someone to check the structure, and if it works, I'll do it step by step. ”

"Okay, no problem, the engineers are ready. Ms. Fu waved her hand, and the twenty or thirty engineers with monitoring devices on her back were all waiting for her.

Many people know that this new project launched by the imperial court will use the latest machines, but in this place that is 100 meters deep underground, a ramp nearly two kilometers long has been specially built to descend. Now at the construction site, all kinds of machinery have long been ready to be assembled, but the so-called new equipment of the imperial court has not been seen in any case. But I saw a bald man walking straight towards the rock and soil layer to be chiseled in front of the track, what the hell is this for?

Yan Wu came to the edge of the rock and soil layer, starting here, he needed to dig a tunnel with a diameter of fifteen meters, and recalled the general structure of the shield machine just now in his mind, and after a blue light flashed, a scarlet body appeared in front of everyone. This is the body of a truck-like machine, except that in front of the sheep-shaped nose, a large grinding disc is installed, which is very similar to the cutter head of the shield machine, except that it is not a radioactive cutter head, but a round hole.

Immediately, the whole construction site was in an uproar, and people saw a human transform into a machine, and their emotions immediately boiled, but they were quickly pacified by the soldiers of the army.

Ms. Fu knew that Yan Wu had superpowers, but she didn't expect that Yan Wu's ability was to simulate machinery, this kind of complex shield machine, which could be transformed into a similar machine with a glance and touch, was simply a miracle. Quietly asked the dumb engineer next to him, "What do you think of this?

The engineer was stunned, and it took a few moments before he reacted, "I don't know, how can this person become a machine? He made this grinding head look like it, but he didn't know if he could dig up the rock layer of the plateau permafrost, and how to transport the excavated soil fragments was also a problem." ”

Ms. Fu nodded, "Let's see how Yan Wu solves it, right?"

"His name is Yan Wu, is he really a person, or is he a superman cultivated by the imperial court?" the engineer obviously also went online, and immediately thought of some secret organization.

"It's nothing, you think too much~" Ms. Fu was speechless, why do people like to associate superpowers now? Is it really a blockbuster movie of American superheroes that I have watched too much?

Yan Wu transformed into a mechanical car, and the grinding disc in front of him began to rotate, and countless blue lights shot out from the radial holes on the grinding disc, and these blue lights shot into the frozen rock layer in front of him, and suddenly became a small hole, and all the dirt and rocks in the small hole disappeared in the blue light. As the grinding disc rotated, the rock structure of the soil began to crumble, the small hole became a large hole, and a prototype of a tunnel with a diameter of 15 meters was revealed.

The permafrost rock layer melted very quickly, almost reaching a speed of three meters per second, and the power of two hundred meters in the previous ground experiment was incomparable, but there was no way, Yan Wu's energy output upper limit was so much, and the overall star power output of a cylinder with a diameter of fifteen meters wide could achieve the current effect.

In just half a minute, a fifty-meter-long tunnel was formed, Yan Wu transformed back and shouted loudly, "Old man, hurry up and arrange someone to come over to check it, the quality is qualified, and I will let it go." ”

As soon as Ms. Fu heard Yan Wu's title, her face changed, she gritted her teeth, regained her composure, and waved her hand, "Everyone must carefully check it, this is a project related to the national fortunes of the Great Xia Dynasty, and you can't be negligent." ”

After twenty or thirty people for half an hour of serious and repeated inspection, the result was of course no problem, Yan Wu's star power not only melted all the soil and rocks in the middle, but also squeezed the surrounding soil and rocks, forming a crystal shell, the ground was clean and clean, the dust was not clean, there was no remnant of the so-called soil and gravel, and the rock wall next to it, if it was not with the help of climbing tools, the inspection engineers could hardly go up.

Ms. Fu, who got an excellent answer, gave Yan Wu a thumbs up, and her hanging heart was retracted, and she could finally submit a perfect answer sheet to her superiors.

One hundred meters a minute, which is a world of difference compared to the speed of 100 meters in ten days with a shield machine, it seems that the excavation project is no longer the focus, the follow-up construction and installation is the center of gravity, the site situation needs to be reported truthfully, and this epic plan needs to make some changes.

There is also the mystery of Yan Wu's ability, judging from his performance now, some clues can be guessed. Yan Wu is very likely to have the ability to simulate machinery, and he can simulate all machinery in appearance and function, but because the energy used and output is unknown, it is not a common mechanical energy output, so there is almost no loss in terms of efficacy, and there is no problem of conversion, which is a big mystery, where did he get so much energy.

The shooting video and progress summary of the scene were immediately sent back to Zitian Pavilion, and the bigwigs were very satisfied with Yan Wu's performance. This money is well spent! As for Yan Wu's ability speculation, everyone tacitly put it aside, it is okay to study secretly, and there must be no small movements, this is not a good stubble.

Yan Wu worked hard in the Gobi Plateau at night like a little bee to make holes. Now there is no problem with the quality of his work, that is, every kilometer, there are technicians and engineers who come to measure the deviation and angle of the path, and then move forward in the direction they instructed, and even have a jeep directly follow the mechanical car that Yan Wu transformed, and guide at any time. There was almost no noise in Yan Wu's work, and all the dirt and rocks were silently melted away by the star power.

Therefore, Yan Wu drilled a hole in the front, and thousands of people followed behind to install various lighting, transport various equipment, and began to seal, level and so on the basis of the tunnel dug by Yan Wu. Even, every five kilometers need to build a 100-meter-high access road to the ground, on which it is necessary to build a water ripple monitoring station; one kilometer is a temporary rest room and tool room deep underground, Yan Wu is always doing it casually, anyway, it is a matter of going down with a shot, less than a few seconds.

Yan Wu went back to Furong Hospital to accompany his little vest during the day, and flew to the Gobi Desert at night to make a hole, and even transformed into a mecha to carry some urgently needed items for the engineering team on the way. Because Yan Wu is fast, and he walks in a straight line in the air, flying from Furong Mansion to the construction site is only twenty minutes away one way. As long as the freight is paid, Yan Wu will not refuse, no matter what you have, often carrying hundreds of tons of containers flying around in the air.

The tunnel project is progressing very smoothly, and the excavation process has been completed by one-fifth in a week, which is simply a god-like speed, making the speed behind far less than Yan Wu's progress. Now the engineering team has expanded to a team of 2,000 people, all of whom are doing follow-up work for the tunnel dug by Yan Wu, and trains are transporting all kinds of materials to the Gobi, which is a busy scene.

All this cannot be concealed from the satellites of the United States in space, and a major event has also happened in the United States during this period. That is, XPACEX, a private company of the United States, successfully launched a heavy rocket with a load of 63.8 tons, which caused a sensation around the world, and many praised the feat of returning the United States to space.

In the office of the president of the United States, a blond man sat behind a desk, on which were pictures of Yan Wu and mecha. Several servicemen and several men in suits stood around him, and Secretary of Defense Nelson was among them.

"Do you think that this man named Yan Wu is the mysterious mecha on the picture?" the blonde president's finger tapped on the photo, his brow furrowed.

"Not bad, according to satellite monitoring and confirmation by agents. This Yan Wu will appear in Furong Mansion during the day, but dedicate himself to the Gobi at night, and it is this mysterious mecha that connects the two. Only this mecha has such speed. We have confirmed that this mecha is the one that appeared in outer space half a month ago and can quickly travel back and forth to Earth. The Minister of Defense reported.

"What are you going to do?" the president asked.

"It seems that the Great Xia Imperial Court has cooperated with this mecha, and they have started a mysterious project on the Gobi in the Western Regions in an attempt to strengthen the national fortune. I suggest a plan to destroy this mech. The director of the Department of Homeland Security said.

"I agree!"

"Agreed, it's just too threatening. This kind of thing can only be in the hands of the United States, if it can't, then destroy it!"

"Do you have any plans? I hope it won't cause a backlash from the Great Xia Dynasty. The blonde president said.

"We can design it out. At the same time, it was planned to kidnap his family and use it as a threat. I guess the Great Xia Dynasty also used his family as a threat to make him compromise. We can do the same. "The director of the Bureau of Homeland Security. "But this requires your approval, we need to activate the agents planted in Seremban, and as soon as this happens, our sleeper personnel in Seremban Mansion for decades may be exposed. ”

"I remember that there was a consulate in the United States of America in Seremban, right?" asked the blonde president.

"Yes, there are six of us officers there. "The director of the Bureau of Homeland Security.

"If the plan fails, you can blow up there, mess up the audition, and buckle it on the head of the Great Xia Dynasty. Then we will have to fight each other. There won't be much to lose. Said the Minister of Defense.

"Are you sure you can destroy or surrender that mech?" the president asked again.

"As long as you fight in the atmosphere, it's fine. It will fly over the high seas, and if it doesn't work, we can use nuclear bombs. I don't believe it can withstand a nuclear bomb. "There's nothing wrong with detonating a nuclear bomb on the high seas, just say we're testing." Anyway, the Great Xia Dynasty hadn't declared that the mecha was their country's. If we announce it, we can ask for a deeper cooperation, but if we don't, we will make a statement that we have discovered a suspected alien and will be the first to attack in order to protect ourselves. Probably, the army will carry the pot. ”

"For the sake of the supreme honor of the United States, we will!" said the generals.

"Let's inform Zhuo Wei Guo and Foot Basin Country that we can't do this alone. Mr. President thought for a moment.

"Yes sir, we'll give them a little bit of information appropriately. The director of the Department of Homeland Security replied. "We also need their cheering to share the pressure. ”
