Blue star road

A moment later, Lei Dong looked at the assembled advance team entering the passage with heartache, but his heart was extremely painful. Although he agreed quite happily, he needed to pay for the doubled money himself, but the superiors would not give it to him. The quote is over the limit!

Of course, Lei Dong was just in pure physical pain, and he didn't have much complaints, because the danger had indeed increased.

In the main passage, there were fallen steel concrete and steel plates everywhere. Chen Wu was holding a weapon and walking in front of Su Bai and others. Just as he said, he would do everything he could to protect them. Su Bai looked at the edge of the passage and was stunned. The deformed support columns and walls spoke to Meng Ding in a low voice.

"Uncle Meng, is this passage normally maintained?"

"It must be maintained. It has existed for thousands of years. No matter how good the craftsmanship is, it cannot withstand the erosion of time. If it is not maintained, the things that collapse will not be what you see in front of you. I will teach you how to distinguish on the spot, those areas that have been maintained later. The color is obviously lighter," Meng Ding said about his experience.

Su Bai looked over carefully and found that there did seem to be some deformed structure areas, and the color was slightly lighter.

Creak~~

The surrounding support pillars made distorted sounds from time to time, giving people a shaky feeling.

Su Bai felt a little nervous when he heard this.

However, Su Bai and the others still had the courage to move forward. There was another team in front of Su Bai and the others. That team was a team of engineers from the military department, and they were responsible for the front-line survey. Whenever they walk a section of the road and determine that it is safe, they will send out a designated message, and the multifunctional light work vehicles and dragon tooth troops behind them will move forward for a certain distance.

It took about half an hour to walk inside.

Chen Wu, who was walking at the front, suddenly stopped.

"What's wrong?" Su Bai asked.

"The team in front has stopped." Chen Wu said simply.

Su Bai squinted and looked ahead through the dim light. The passage directly in front seemed to be blocked! The team of engineers in front seemed to be surveying.

At this moment, a captain in the front team turned around and waved his hand towards Chen Wu, making a gesture.

Chen Wu turned around and said to Su Bai and others.

"There is a cave-in area ahead and we need your help."

"Let's go." Meng Ding nodded.

Approaching the collapse area, Su Bai saw at a glance the twisted reinforced concrete, gravel, lines and steel plates blocking the road. At first glance, it looked chaotic and without a clue.

An old engineer who looked older walked up to Meng Ding and said.

"I am Wu An, an engineer who specializes in tunnel restoration. I heard from them that you are the best dismantlers. This collapse cannot be dismantled by force. Part of it must be dismantled manually, and then the supports are built bit by bit. Finally, use mechanical work.”

Meng Ding was silent for a few seconds and said, "Yes, but we have a request."

"You say."

"You can specify the points, but we have the final say on how to dismantle them. Anyway, as long as we can meet your requirements in the end!" Meng Ding requested.

"No problem, this is reasonable."

"Work has started!" Meng Ding said to Su Bai and others.

"okay!"

Deep in the dark and deep passage, there were constant crashing sounds.

In the private room, Ye Ying closed her eyes and listened quietly to the impact sound and frequency.

She needs to be on high alert at all times.

Suddenly Ye Ying opened her eyes suddenly, and she heard a scream!

One of the carriages was breached. Ye Ying looked at the watch and the time she expected to pass. It was only half the time.

Of course, this is not surprising, because when a train derails, some parts will definitely be damaged, and damaged carriages are naturally more fragile!

But this is not good news, because the partitions between the carriages are not as hard as the outer armor of the train, which is equivalent to shortening the safety time in disguise!

Boom!

There was a sudden knock on the door of Ye Ying's room.

"Open the door! Let us in!"

Hearing the cry for help, Ye Ying's heart sank slightly. It was impossible for the people in this carriage to come out and knock on the door. There was only one possibility. These people came from the next carriage to open the connecting passage in the middle, and she just heard The screams that arrived were from the car next door.

But Ye Ying didn't open the door.

The reason is simple. Her private room is very small and can accommodate only a very limited number of people. She clearly heard a lot of footsteps, which meant that a large number of people gathered at her door. People tend to lose their minds when they are afraid.

And this carriage is different from other carriages. It belongs to an area where relatively wealthy people live, and it is impossible to open the door casually.

Once you open the door stupidly, there is a high probability that you will be put in danger!

So Ye Ying chose to remain silent!

Sure enough, the people gathered outside began to curse angrily after receiving no response!

"You dirty and cowardly fellow! Open the door for us quickly, or we will break through with brute force!"

"Open the door, or we won't be polite!"

…

"Please open the door quickly. There are children and old people here! Just do it."

…

Ye Ying closed her eyes as if she didn't hear it, not because she was cruel, but because she was sensible enough.

She calmed herself down.

At the entrance of the passage, Su Bai's eyes were fixed on the steel and gravel in front of him. He dug out bit by bit. Every time he dug out a piece, some tiny gravel and dust would fall from the surrounding walls. Sweat dripped from Su Bai's forehead. The entire clothes were soaked. After all, the cement layer was not as strong as the steel layer.

The overall structure of the entire tunnel is composed of a steel layer and a cement pouring layer, which are superimposed back and forth. The central tunnel is on the cement pouring layer, which is also the most fragile layer.

Er Gouzi and the others watched Su Bai working with dry throats.

Su Bai cut and buckled it out bit by bit. The entire robotic arm was very stable. He had to clear a small opening first so that he could easily reach in and reinforce it.

Everyone present looked at it with excitement.

Finally, Su Bai dug out an opening smoothly.

"Beautiful! Go up and reinforce it! Clean out the objects on the side!" Meng Ding said excitedly, and he also admired it sincerely! It's really an amazing balance. When Su Bai was asked to do this before, he was still very worried, but there was nothing he could do about it. Only Su Bai among them was equipped with an auxiliary mechanical arm and could work with such power.

Ergouzi and others immediately rushed forward!

Soon this point was reinforced bit by bit!

Su Bai used this method to open an opening on the other side, first put in the retractable roof, and then cleared the space to put in the steel columns. Of course, it was not just the collapsed area that was reinforced, support steel columns were placed along the way.

"That's it!" Meng Ding turned to the people waiting behind him and said.

"Start homework!" Wu An didn't hesitate at all.

Immediately, those multifunctional mechanical vehicles drove up and began to clean up the collapsed steel and gravel in the middle!

Rumble~~

Pieces of reinforced concrete boards were cut open and then pulled out with brute force!

"Great! It's open!" the staff shouted in surprise.

In front of them, a mini passage that could accommodate a mechanical vehicle was cleared, and all workers immediately stopped working.

"keep going!"

Everyone was stunned for a moment, glanced at Chen Wu, but then moved on! Obviously, their top priority is to save people, and they will talk about the other things later!

As soon as Su Bai took a few breaths, he followed up with a dark face. It must be said that this group of people was moving very fast. After running for more than half an hour, Su Bai was out of breath. It seemed that he had time to work hard. Take care of and exercise your body.

After Chen Wu saw it, he retreated directly in front of Su Bai without saying a word.

"I'll carry you!"

"ah?"

"Let's go!" Chen Wu didn't say anything, just picked up Su Bai and ran forward!
