"Buzz! Buzz!"
The threaded drill bit rotated extremely fast, and the roaring sound was sharp and shrill. The police officers several hundred meters away were driven back by the strong wind.
"Buzz!"
"Buzz buzz..."
A police officer squatting behind the police car tightened his coat, turned to look at his colleague and said, "Brother Zhang, this big guy has been spinning for more than five minutes. Why is he just spinning but not digging?"
"High technology, you don't understand." The police officer named Brother Zhang squinted his eyes and looked at it enthusiastically: "It's obviously a warm-up."
"It's already very hot and the snow has melted all around."
"It just wasn't hot enough."
Police officer: “…”
"Buzzing..."
After another two minutes, the rotation speed of the drill bit began to gradually slow down until it stopped completely.
An unaccustomed silence returned to the vast construction site.
"what happened?"
"No more turning?"
"Is there no oil..."
While many police officers were discussing, the maglev train suddenly sounded Chen Yu's voice, amplified a hundred times: "Hello? Friends outside, can you find me some excavators? Pad the angles? What's wrong with the drill bits of this piece of shit? Can’t reach the ground.”
Everyone: "..."
Seven minutes later, the person in charge of the site called in five excavators that were performing road maintenance not far away and began the "raising" operation.
In the train, Chen Yu faced the camera and was slightly embarrassed: "It's a waste of emotion. The crawler tracks of the first car were raised to the highest level, but the drill bit on the front of the car still couldn't penetrate into the ground. This is not my fault, and it has nothing to do with the operation. This is There is a bug in the design of this engineering vehicle.”
"Train conductor, in smart mode, the angle adjustment of the carriage is limited. You can operate it manually." The crystal ball lit up and a mechanical electronic synthesized sound came out.
"Stop talking nonsense." Chen Yu waved his hand: "This is not a manual or automatic problem, this is a flaw in your design."
"In smart mode, in order to ensure safety, the angle adjustment of the car is limited, please perform manual operation." The artificial intelligence repeated.
"King." Xiao Taohong raised her hand and suggested, "How about you perform manual operation."
"No!" Chen Yu sternly refused: "We are an evaluation agency, and we have the obligation to correct problems and mistakes when we find them. Use manual once, use manual twice, and use manual every time, so what is the use of this smart mode? ?”
"Ouch!" Xiao Taohong nodded in surprise: "That's the truth."
"Train conductor, in smart mode, in order to ensure..."
"you shut up!"
"Okay conductor."
Under the gaze of more than four million viewers, Chen Yu fully demonstrated the level and persistence of a professional evaluator.
"Boom!"
Ten minutes later, outside the train, an excavator "knocked" on the window twice with its hook, indicating that the paving was completed.
Chen Yu turned on the communication and shouted: "Thank you very much, please retreat now, as far away from me as possible."
Waiting for the five excavators to line up to leave, he raised his wrist, slid his watch, and said: "During the construction process, the outside of the train is more interesting than the inside. So in order to give everyone an intuitive and shocking view To experience it, I will set the camera outside so that you can witness the entire construction process of the engineering vehicle."
As soon as he finished speaking, he controlled the camera to fly out of the train, and then ordered the artificial intelligence to move the train, climbed up the upturned soil slope, pointed the drill bit downward, and restarted the digging operation.
"Swish-swish!"
The huge drill bit made of carbon alloy started spinning again, and the gushing heat waves and strong winds kicked up countless dust.
"Set off!"
"Buzz..."
The tracks of the first carriage were raised, increasing the vertical angle of the front of the vehicle. As the vehicle slowly moved forward, the sharp threaded drill bit finally touched the ground.
"Boom, boom, boom!!"
Just hearing a series of roars similar to a landslide, the threaded drill bit penetrated, broke, and tore into the ground neatly, going deep...
[Oh oh~ Groove!]
[The sparks are rising.]
[My phone is vibrating.]
[Awesome! (Breaking sound)]
[I was just outside the construction site, and my feet were numb from the shock.]
[Mechanical Engineering! What a man’s romance!]
[Wrong, it’s the happiness of a rich woman!]
[Happy rich woman +1!]
[Happy rich woman +2!]
[I don’t want to watch the construction! I want to see the female assistant!]
[The female assistant is a eunuch today...]
With the roar reverberating, tons and tons of soil and gravel were drawn into the receiving port on the middle side of the front of the car through the grooves. Under the ultra-high temperature and ultra-high pressure internal environment, they turned into soft semi-solid matter.
As the thread-shaped drill bit breaks through the ground, the terrifying drag force generated by the surrounding soil also greatly speeds up the penetration of the engineering vehicle.
The three-hundred-meter long train, under the two drag forces and the crawler driving force, disappeared like a swift and poisonous snake into a hole with a radius of eighteen meters...
The camera suspended in the air paused for half a second, and then pursued it at a faster speed.
Inside the cave, it's not completely dark.
Because the surroundings are covered with a solid material similar to magma, the soil processed by high temperature and high pressure has not completely cooled down and still emits a reddish light.
"Boom boom boom..."
Deep in the cave, the train was no longer visible, but the violent vibrations and roars still echoed in the live broadcast room.
The camera, controlled by Chen Yu, slowed down its flight speed.
More than four million viewers were able to see the detailed structure of the pseudo-vacuum pipe, which was an eye-opener.
Every three hundred meters, a cylinder will be erected in the middle of the pipe to support the pressure from both sides.
"Whoosh—"
After visiting for several minutes, the camera started chasing the train at a terrifying speed.
The speed was so fast that the screen in the live broadcast room turned faintly red...
This is the high temperature and burning caused by the friction between the lens and the air.
[So fast! So hot! ah!]
[? ?]
[]
[The speed is so fast that I can’t see clearly.]
[Let me just say that the cameraman is the most awesome.]
[I have seen it on site, it seems to be an invisible camera.]
[Can the camera be invisible? !]
[What the hell? Can you become invisible?]
[Suddenly I had a bold idea...]
Ten seconds later, when the suspended camera caught up with the rapidly excavating engineering vehicle, everyone saw clearly the entire process of making the vacuum pipeline.
Simply put, there are only three steps.
1. Drill bit to dig soil. While breaking the soil, the earth and rock fragments are also sent into the circular container in the middle of the front of the vehicle along the groove.
Second, make the pipeline. The soil enters the container and quickly solidifies into a semi-solid substance under high temperature and pressure. It is squeezed out from the thousands of diffusion holes at the back of the container like toothpaste.
Third, the front bezel is expanded. The extruded semi-solid material sticks to the cave wall and is further squeezed by the expanded front bezel at the front and rear of the car, forming a tubular structure that is integrated with the cave wall.
In this way, the three-step coordinated operation left a relatively stable pipeline behind the engineering vehicle...
Inside the train cab.
Chen Yu carefully observed the virtual road map in front of him and said to his watch: "The current depth is minus 1,000 meters above sea level, and the moving speed is 520 kilometers per hour, which is much faster than a train. With such excavation efficiency , if there are no surprises..."
"It takes at most two hours to reach the Magic City."
"The first 'teleport' channel in human history is about to be born."

(Only one chapter has been updated tonight, and the second chapter is still more than 300 words short. I suddenly became depressed around eight o'clock, with chest tightness and trembling, and confused thinking...
I'll try to make up for it tomorrow. )
