"Buzz! Buzz!"

The threaded drill bit rotated at an extremely fast speed, and the roaring sound was sharp and shrill. Police officers hundreds of meters away were all retreated repeatedly by the strong wind.

“Buzz!”

“Buzz buzz…”

A police officer squatting behind the police car tightened his coat, turned his head to look at his colleague and said, "Brother Zhang, this big guy has been spinning for more than five minutes, why are he just spinning but not digging?"

"High-tech, you don't understand." The policeman named Brother Zhang narrowed his eyes and looked excitedly: "It's obviously preheating."

"It's already very hot, and the snow around it has melted."

“That’s not hot enough.”

Police officer: "…"

“Buzz…”

After another two minutes, the drill bit's rotation speed began to gradually slow down until it stopped completely.

The vast construction site has restored an unacceptable silence.

"What's going on?"

"No more turn?"

"Is there no oil..."

Just as many police officers were talking, the maglev train suddenly sounded Chen Yu's voice after expanding a hundred times: "Hey? Friends outside, can you find me a few excavators? Put the angle up? This broken drill bit cannot reach the ground."

Everyone: "..."

Seven minutes later, the on-site person in charge found five excavators that were carrying out road maintenance not far away and began the "high-rise" operation.

In the train, Chen Yu faced the camera a little embarrassed: "It's a bit of a waste of emotion. The tracks in the first car were raised to the highest level, and the drill bit on the front of the car still couldn't penetrate into the ground. This is not my reason, and it has nothing to do with the operation. This is a bug in the design of this engineering vehicle."

"The train conductor, in intelligent mode, the angle adjustment of the car is limited, you can perform manual operations." The crystal ball lights up, and the mechanical electronic synthesizing sound is emitted.

"Don't talk nonsense." Chen Yu waved his hand: "This is not a manual and automatic problem, it is a flaw in your design."

"In intelligent mode, in order to ensure safety, the angle adjustment of the car is limited, please perform manual operations." Artificial intelligence repeats.

"Wang." Xiao Taohong raised her hand and suggested: "Or you can do manual operations."

"No!" Chen Yu refused sternly: "We are an evaluation agency. If we find problems and errors, we have an obligation to correct them. Use manual one time, manual two times, and manual every time. What's the use of this smart mode?"

"Ao!" Xiao Taohong nodded in surprise: "This is the reason."

"Train leader, in intelligent mode, to ensure..."

"Shut up!"

"Okay train conductor."

With the attention of more than four million viewers, Chen Yu fully demonstrated the level and persistence of a professional reviewer.

"Dongdong!"

More than ten minutes later, outside the train, an excavator "knocked" the window twice with his hook claws, indicating that the preparation was completed.

Chen Yu turned on the communication and shouted: "Thank you very much. Please retreat now, the farther away from me, the better."

Waiting for five excavators to leave in line, he raised his wrist and slid his watch while saying, "During the construction process, the outside of the train is more eye-catching than the inside. So in order to give everyone an intuitive and shocking experience, I will set the camera outside so that you can see the construction process of the construction of the engineering vehicle throughout."

After saying that, he controlled the camera to fly out of the train, and then ordered the artificial intelligence to move the train, climbed up the tiptoe slope, drill bit down, and started digging again.

"Swoosh-swoosh!"

The huge drill bit made of carbon alloy rotated again, and the gushing heat waves and strong winds drove away countless dust.

"Set off!"

“Buzz…”

The first car track was raised, increasing the vertical angle of the front. As the whole vehicle slowly moved forward, the sharp threaded drill bit finally touched the ground.

"Boom rumble!!"

I heard a series of roars similar to landslides, and the threaded drill bits pierced the ground in a neat way, breaking, tearing, and going deeper...

【Oh ~ Slot!】

【Spit Mars.】

【My phone is vibrating.】

【Awesome! (Breaking the sound)】

[I am just outside the construction site, my feet are numb.]

【Mechanical Engineering! It’s really a man’s romance!】

【Wrong, it is the happiness of the rich woman!】

【Happy rich woman +1!】

【Happy rich woman + 2!】

[I don't want to look at the construction! I want to look at the female assistant!]

【The female assistant is eunuch today…】

With the roar echoing, tons of soil and gravel are rolled into the storage port on the middle side of the front of the vehicle through the grooves, and turned into soft semi-solid substances under the internal environment of ultra-high temperature and ultra-high pressure.

The threaded drill bit breaks through the ground and the terrifying drag force generated by the surrounding soil has also greatly accelerated the in-depth speed of the construction vehicle.

The three hundred meters long train, under these two drag forces and the driving force of the track, was like a swift poisonous snake, drilling into a hole with a radius of 18 meters and disappearing...

The camera suspended in the air paused for half a second and chased in at a faster speed.

Inside the cave, it is not completely dark.

Because the surroundings are covered with solid substances similar to magma, the soil processed by high temperature and high pressure has not completely cooled down and emits a slightly red light.

"Boom boom boom..."

Deep in the cave, the train could no longer see any shadows, but the violent vibration and roar were still echoing in the live broadcast room.

The camera slowed down its flight speed under Chen Yu's control.

More than four million viewers were able to see the subtle structure of the pseudo-vacuum pipeline, which was a big pleasure.

Every three hundred meters, a cylinder is erected in the middle of the pipeline to support the pressure transmitted from both sides.

"Swoosh--"

After visiting for a few minutes, the camera burst into terrifying speed and chased towards the train.

The speed is so fast that the picture in the live broadcast room is faintly red...

This is the high temperature and burn 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.】

[I just say that the cameraman is the most awesome.]

[I have seen it on the spot, it seems to be a camera that can be invisible.]

【Can the camera be invisible?!】

【Damn? Can it be invisible?】

【Suddenly I had a bold idea…】

After more than ten seconds, when the floating camera catches up with the fast-digging engineering vehicle, all the people can see the entire process of vacuum pipeline production directly.

Simply put, there are only three steps.

1. The drill bit digs the soil. While breaking the soil, it also sends the soil and stone fragments along the groove into the circular container in the middle of the front of the vehicle.

2. Making pipes. The soil enters the container and quickly condenses into semi-solid substances under high temperature and high pressure. It is squeezed out like toothpaste from thousands of diffusion holes behind the container.

3. The front bezel is expanded. The extruded semi-solid substance is stuck to the hole wall and is further squeezed by the front bezel that expands at the front and rear of the car, forming a tubular structure that is integrated with the hole wall.

In this way, three steps coordinated operation left behind a relatively stable pipeline...

Inside the train cab.

Chen Yu carefully observed the virtual road map in front of him and said to the watch: "The current depth is minus 1,000 meters on the sea level, and the movement speed is 520 kilometers per hour, which is much faster than the EMU. With such excavation efficiency, if nothing unexpected happens..."

"You can get to the Magic City in two hours at most."

"The first 'teleport' channel in human history is about to be born."

(There is only one chapter tonight, and the second chapter is still more than 300 words short of the past eight o'clock. The depression suddenly broke out, and I was trembling all over, my mind was confused, and I couldn't write it.
Chapter completed!
