() "Buzz!

The threaded drill bit rotated at great speed, and the roar was sharp and poignant. The police officers a few hundred meters away were blown back again and again by the strong wind.

"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 is it only turning and not digging?"

"High-tech, you don't understand. The police officer named Brother Zhang squinted his eyes and looked at the positive energy: "It's obviously warming up." ”

"It's already hot and the snow is melting all around. ”

"It's just not hot enough. ”

Officer: "......"

"Buzz ......"

After another two minutes, the speed of the drill began to slow down until it stopped.

In the vast construction site, an unpleasant silence was restored.

"What's going on?"

"Not turning?"

"Is it out of gas......

Just as many police officers were discussing, the maglev train suddenly sounded Chen Yu's hundredfold voice: "Hey, friends outside, can you find me a few excavators? ”

Everyone: "......"

Seven minutes later, the person in charge of the site found five excavators that were not far away to carry out road repairs and began the "elevation" operation.

Inside the train, Chen Yu faced the camera and was slightly embarrassed: "It's a waste of feelings." The track of the first carriage rose to the highest, and the drill bit at the front of the car still could not penetrate the ground, which is not my reason, and it has nothing to do with the operation, this is a bug in the design of this engineering vehicle. ”

"Conductor, in smart mode, the adjustment of the angle of the carriage is limited, and you can operate it manually. The crystal ball lit up, emitting a mechanical electronic synthesized sound.

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

"In smart mode, in order to ensure safety, the angle adjustment of the cabin is limited, so please operate it manually. "Artificial intelligence is repetitive.

"King. Little Peach raised her hand and suggested, "Otherwise, you can do it manually." ”

"No!" Chen Yu sternly refused: "We are evaluation institutions, and we have the obligation to correct problems and mistakes when we find them." Use it manually once, use it twice, and use it manually every time, so what's the use of this smart mode?"

"Whew!" Little Peach nodded in surprise: "That's the truth." ”

"Conductor, smart mode, in order to ensure ......"

"Shut up!"

"Good conductor. ”

In the gaze of more than 4 million viewers, Chen Yu fully demonstrated the level and persistence of a professional evaluator.

"Knock knock!"

More than ten minutes later, outside the train, an excavator "knocked" the window twice with a hook to signal that the paving had been 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 the five excavators to line up, he raised his wrist and slid his watch as he 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 experience, I will set the camera outside and let you witness the construction process of the construction truck. ”

As soon as the words fell, he controlled the camera to fly out of the train, and then ordered the artificial intelligence to move the train, climbed the tiptoe slope, and the drill bit pointed down, and started digging again.

"Whoosh-whoosh!"

The huge carbon alloy drill bit spun again, and the heat and wind swept up a lot of dust.

"Let's go!"

"Buzz ......"

The tracks of the first carriage were raised, increasing the vertical angle of the nose, and the sharp thread drill finally touched the ground as the vehicle slowly moved forward.

"Boom Boom!!"

Listening to a series of roars that resembled a landslide, the thread drill bit simply pierced the ground into, broken, torn and deep into the ......

Oh oh ~ slot!

Rising to spark.

My phone is vibrating.

Awesome!(Broken sound)

I was just outside the construction site, my feet numb.

What a man's romance!

Wrong, it's the happiness of a rich woman!

Rich woman happy +1!

Rich woman happy +2!

I don't want to look at construction! I want to see female assistants!

The female assistant is a eunuch today......

With a roaring reverberation, tons and tons of dirt and gravel are swept into the containment opening on the middle side of the front of the car through the grooves, and turn into a soft semi-solid substance in the internal environment of ultra-high temperature and ultra-high pressure.

The thread-shaped drill bit, while breaking the ground, and the terrifying drag force generated by the surrounding soil, also greatly accelerated the depth speed of the engineering vehicle.

The 300-meter-long train, under these two drag forces and crawler propulsion, disappeared like a swift poisonous snake into a hole in the ground with a radius of 18 meters......

The camera suspended in the air paused for a second before chasing it at a faster speed.

Inside the cave, there is no end to the darkness.

Because it is coated with a solid material similar to magma, the soil that has been processed at high temperature and pressure has not been completely cooled, and it still emits a reddish glow.

"Boom, boom, boom......"

In the depths of the cave, the train can no longer see the shadow, but the violent vibration and roar are still echoing in the live broadcast room.

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

More than 4 million viewers were able to see the subtle structure of the pseudo-vacuum pipe, which was more than addictive to the eyes.

Every 300 meters, a cylinder is erected in the middle of the pipe to support the pressure coming from both sides.

"Whoosh-"

After a few minutes of visiting, the camera erupted at a terrifying speed and chased towards the train.

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

This is the high temperature and scorching caused by the friction of the lens against the air.

It's fast! It's hot!

？？

???

It's so fast that I can't see it clearly.

I'll just say that the videographer is the best.

I've seen it at the scene, and it seems to be a camera that can be invisible.

Can the camera be invisible?!

Can you be invisible?

Suddenly there was a bold idea......

More than ten seconds later, when the hovering camera caught up with the fast-digging engineering truck, everyone watched the process of making the vacuum pipe.

To put it simply, there are only three steps.

First, the drill bit digs the soil. At the same time as the ground is broken, the earth and stone fragments are fed along the grooves into a circular container in the middle of the front of the vehicle.

Second, make pipes. The soil enters the container, quickly condenses into a semi-solid substance under high temperature and pressure, and is squeezed out like toothpaste from thousands of diffusion holes behind the container.

Third, the front bezel is expanded. The extruded semi-solid material sticks to the cave wall and is further squeezed by the front bezel of the inflated front and rear of the car, forming a tubular structure that condenses into the cave wall.

In this way, the three-step coordinated operation left a fairly 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 at sea level, and the moving speed is 520 kilometers per hour, which is much faster than a bullet train. With such excavation efficiency, if there are no surprises......"

"It will take you two hours at most to get to the magic capital. ”

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

......

(There is only one chapter added tonight, and the second chapter is still more than 300 words away, and the depression suddenly occurred at eight o'clock, trembling all over, thinking confused, and unable to write.)

I'll try to make it up tomorrow. ）
