After a while, Lei Dong looked at the assembled advance team and entered the passage with pain, but his heart was extremely painful, although he promised to be quite refreshing, but he needed to solve the doubling of the money himself, and the above would not be reported, it was exceeded!

Of course, Lei Dong is just a pure flesh pain, and he doesn't complain too much, because the danger has indeed increased.

Inside the main passage, there were falling steel concrete and steel plates everywhere, Chen Wu walked in front of Su Bai and the others with a weapon in his hand, just as he said, he would do everything to protect them, Su Bai looked at the supporting pillars and walls that were deformed at the edge of the passage, and said to Meng Ding in a low voice.

"Uncle Meng, is this passage usually maintained?"

"It must be maintained, it has existed for thousands of years, no matter how good the process is, it can't withstand the erosion of time, if you don't maintain the collapse, it's not what you see in front of you, teach you how to distinguish on the spot, those areas that have been maintained later, the color is obviously lighter." Mundin spoke of his experience.

Su Bai looked over carefully and found that there seemed to be a part of the deformed structure area, and the color was slightly lighter.

Creak~~

The supporting columns around it, from time to time, make a distorting sound, giving people a crumbling feeling.

Hearing this, Su Bai's psychology was a little hairy.

However, Su Bai and the others still walked forward, Su Bai and they still had a team in front of them, that team was the engineer team of the military department, and they were responsible for the survey at the front. Whenever they walk a certain distance and determine that a certain distance is safe, a specified message will be issued, and the multi-purpose light operation vehicle and the dragon tooth unit behind will advance a certain distance.

I walked inside for about half an hour.

Suddenly, Chen Wu, who was walking in the front, stopped.

"What's wrong?" Su Bai asked.

"The line ahead stopped." Chen Wu said simply.

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

At this moment, a captain in the team in front of him turned around and waved his hand at Chen Wu and made a gesture.

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

"There's a subsidence area ahead, and we need your help."

"Let's go." Meng Ding nodded.

Approaching the collapsed area, Su Bai saw at a glance the crooked concrete, gravel and steel plates blocking the road, and he didn't have a clue about the chaotic past.

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

"I'm Wu An, an engineer who specializes in tunnel repair, and I heard them say, you are the best dismantling engineers, this collapse cannot be demolished by brute force, and a part of it must be demolished manually, and then the scaffolds are built little by little, and finally the mechanical operation is used."

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

"You say."

"You can designate the point, but how to dismantle it, we decide by ourselves, anyway, we can meet your requirements in the end!" Mundin demanded.

"No problem, this one is reasonable."

"It's time to start!" Meng Ding said to Su Bai and the others.

"Okay!"

In the dark and deep passages in the depths, there was a constant sound of crashing.

In the private room, Ye Ying closed her eyes and quietly listened 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!

A carriage was broken through, Ye Ying looked at the table below and the time she expected to pass, only half of it had passed.

Of course, there is nothing surprising about this, because when the train derails, some of it will definitely be damaged, and the damaged carriages are naturally more vulnerable!

But this is not good news, because the hardness of the partition layer in the middle of each carriage is not as strong as the outer armor of the train, which is equivalent to shortening the safety time in disguise!

Knock knock!

Ye Ying's room door suddenly came with a sharp knock.

"Open the door! Let's get inside!"

Hearing the sound of distress, Ye Ying's heart sank slightly, it is impossible for the people in this carriage to come out and knock on the door, there is only one possibility, these people came from the connecting passage in the middle of the next carriage, and the screams she heard just now were from the next carriage.

However, Ye Ying did not open the door.

The reason is simple, her private room is small and can accommodate a very limited number of people, and she can clearly hear a lot of footsteps, that is, a large number of people gathering at her door, and people tend to lose their minds in situations of fear.

And this carriage is not quite the same as other carriages, it belongs to the area where 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 put yourself in danger!

So Ye Ying chose to be silent!

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

"You filthy coward! Open the door for us, or we'll break it with brute force! ”

"Open the door, or we're welcome!"

……

"Please, open the door, there are children and old people here! You're okay. ”

……

Ye Ying closed her eyes as if she hadn't heard, not because she was ruthless, but because she was rational enough.

She calmed her mind.

At the entrance of the passage, Su Bai's eyes were staring at the steel and gravel in front of him, he dug it out little by little, and every time he dug out a piece, some fine gravel and dust would fall on the surrounding walls, Su Bai's forehead sweat kept dripping, and his entire clothes were soaked.

Ergouzi and the others watched Su Bai doing his homework with a dry throat.

Su Bai deducted it little by little, and the entire mechanical arm was very stable, he had to clear a small opening first, and then it was convenient to reach in and reinforce.

The hearts of everyone present were raised.

In the end, Su Bai dug out a hole smoothly.

"Beautiful! Go up and reinforce! Clean up the objects on the side! Meng Ding said with some excitement, he also sincerely admired! It's really a great balance, and he was still very worried about letting Su Bai do it at this time, but there was no way that only Su Bai among them was equipped with an auxiliary mechanical arm and had so much power to work.

Ergouzi and the others immediately rushed up!

Soon this point was reinforced little by little!

Su Bai then used this method to open an opening on the other side, first put it into the telescopic roof, and then cleared the position and put it into the steel column, of course, it was not only the collapsed area that was reinforced, but also the supporting steel columns were placed along the way.

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

"Start your homework!" Wu An did not hesitate at all.

Immediately, those multi-functional mechanical vehicles drove up and began to clean up the collapsed steel rubble in the middle!

Thundered~~

Pieces of reinforced concrete slabs are cut open and then pulled out by brute force!

"Great! It's on! The operator shouted in surprise.

A mini-passage large enough to accommodate a mechanical vehicle was cleared, and all workers immediately stopped working.

"Keep going!"

Everyone was also stunned and glanced at Chen Wu, but then continued to move forward! Obviously, their first priority is to save people, and the rest will come back to that!

Su Bai didn't take a few breaths, he followed with a black face, I have to say that the speed of this group of people is still fast, after running for more than half an hour, Su Bai is out of breath, it seems that he has time to recuperate and exercise his body.

After Chen Wu saw it, he didn't say a word, and retreated directly to the front of Su Bai.

"I'll carry you!"

"Huh?"

"Let's go!" Chen Wu didn't have any nonsense, he directly picked up Su Bai and ran forward!
