On the edge of the collapse of the F1 area, Zhang Lingyue looked at the hot workers below and asked again with an expressionless face.

"Where has the advance force gone?"

"We have advanced to the forty-six kilometer area of the train collapse area, and we are almost halfway through the journey!"

"How long has it been since the accident."

"It's been 14 hours!"

"How long do you expect it to take to reach the target area?"

"At least 24 hours." The overseer next to him explained timidly.

"There is not so much time for you, the daylily is cold for 24 hours, and the people in the train are estimated to have been gnawed and their bones are gone, tell the advance troops, let them speed up, and give them 4 hours at most!"

"4 hours !!"

The overseers on the side were about to faint when they heard it!

"It's 4 hours, if it's all dead inside, what else can we save? Can't even recover the corpses and avenge them? Do you think I'm right? Zhang Lingyue's face was tight, giving people a sense of oppression that could not breathe.

"We get it, and we'll let it go."

In the tunnel, the advance team stopped again, Su Bai's mouth opened into an O-shape, and sure enough, the more worried he was, what happened!

There is a fault in the tunnel in front of you! If it's an ordinary fault, forget it, the key is not an ordinary fault.

The length of the whole fault is about 50 meters, there is a sinkhole in the middle, and the opposite fault mouth is also squeezed by collapse, and the entire mouth on the opposite side seems to be sealed.

"What now?" Everyone looked at each other, a little overwhelmed.

Engineer Wu An's old face was also a little black, and this time it was a big trouble.

The fault obstructs the mechanical operation vehicle, and the collapse mouth needs mechanical operation, which is a dead end.

If they had enough time, it wouldn't be a big deal, just build a makeshift bridge to get there, but they didn't have much time.

At this time, a soldier came running from behind, out of breath.

"The latest order, the death order from above, is to get us through in four hours!"

"I'm rubbing! Who gave the order, idiot? If you are told four hours, you may not be able to get in even if you give us forty hours. The second dog squirted angrily.

"Two dogs!" Meng Ding shouted to the second dog.

Ergouzi closed his mouth unwillingly, Su Baichang took a long breath and said to Meng Ding: "Actually, what Ergouzi said is not completely wrong, this is outrageous, I want to scold!" ”

In the good-natured people can not stand it.

This is also the case, and the entire personnel of the advance team are boiling.

On the contrary, Chen Wu and the members of the Dragon Tooth Squad on the side fell silent, their duty was to obey orders.

Meng Ding pondered for a few seconds, walked up to Wu An and asked, "Teacher Wu An, what do you think should be done next?" ”

"In fact, it is not completely impossible to get to the trapped area of the train within four hours, but the conventional method is not working." Wu An's somewhat tangled reply.

Chen Wu and the others looked at Wu An one after another.

"How?"

"From here!"

Suddenly the air was quiet, no one said a word, the corners of Su Bai's mouth were twitching, go down from the fault, and then climb up? Or hang on the wall in the past?

After a few minutes, Chen Wu opened his mouth to break the silence and asked, "Can you pass from below?" ”

"It's just possible, I'll show you a drawing, this is a thumbnail of this area before the accident, below the main channel, in fact, the troposphere of the pipeline, that is, the small pipeline area, these pipelines are crooked, but at least dozens of them can lead to the train area, but things are not as simple as they seem on the surface, and we don't know the situation of these small pipelines, whether they have collapsed or what, not to mention other dangerous types." Wu An opened the panel of the portable computer he was carrying, and a complex diagram of the underground pipeline appeared.

"What you mean is that there is a chance that these dozens of small pipes lead to the train area, but you're not sure which one is still intact."

"That's right." Wu An nodded.

Without any hesitation, Chen Wu turned his head and said to the team members behind him.

"Everyone, prepare! Let's go down! ”

"Yes!"

The rest of the Dragon's Tooth team members did not hesitate to prepare.

"Wait a minute, if you simply go down, you may not be able to do it, you still have to bring professional personnel, the pipeline below is already very complicated, plus affected by external forces, now it is even more unclear what the situation is, of course we will go down." Wu An explained.

Chen Wu and the others' eyes fell on Su Bai and the others.

"Don't look at us, if you need us, we'll go with you!" Meng Ding was not afraid at this time, because even if he was afraid, he had no choice.

"Good!" Chen Wu nodded.

Thirty-two teams were soon divided into those present, each team was equipped with seven people as standard, five dragon tooth squad combatants, two auxiliary personnel, and the rest stayed in place.

Climbing ropes were shot out and hit the opposite wall, with their respective passages under the ropes.

Su Bai and Ergouzi were assigned to a group, led by Chen Wu, and the rest were assigned to other teams.

Su Bai stood on the edge of the cliff and looked down, at least a few hundred meters deep!

And the pipe mouth they were about to enter was forty-six meters directly below the opposite side, and if they didn't fall well, they would probably have become meatloaf.

"Buckle up, we're going to swing over!" Chen Wu said to Su Bai and Ergouzi.

"Okay." Su Bai and Ergouzi hurriedly buckled the safety buckle.

"Let's go!" Chen Wu shouted crisply.

Suddenly, a member of the team jumped down the rope with a neat jump.

Before Su Bai could react, Chen Wu grabbed Su Bai's waist seat belt with one hand and jumped down with him!

"I'll go!" Su Bai was taken aback, and before he could react, the whole person was already falling freely and throwing over.

It took a few seconds to swing over, and Chen Wu also landed on the opposite wall with one foot to prevent hitting the wall, and then his body slid rapidly, and after falling to a certain extent, he pressed the safety buckle on his waist, and suddenly the two began to slow down!

Su Bai felt his internal organs tumbling! Sure enough, if you don't have professional training, you just can't bear it.

Then it stopped, impartially, just at the mouth of a pitch-black pipe!

The rest of the team also slipped nearby.

"Exciting!" The second dog shouted excitedly to Su Bai.

"Stimulate a yarn!" The corners of Su Bai's mouth are twitching! Fortunately, I was prepared, otherwise my soul would be scared away by such a toss.

Soon after, Su Bai and the seven people successfully drilled into the underground pipe mouth, but the entire pipe mouth was extremely dark, without a trace of light, but a faint sound of water droplets could be heard, of course, accompanied by a strong smell of stinky ditch, which was inevitable.

Chen Wu and the others raised their hands and pressed a small button on the helmet, and suddenly their helmets lit up, but the light was not very dazzling, but very soft, but the lighting effect was very good.

"You follow." After Chen Wu finished speaking, he took the lead and cautiously took the lead to go inside.

Su Bai and Ergouzi followed behind, looking around from time to time.
