"You're going to search? How will you search? Do you really think you can find them? Moreover, with your delicate and tender skin, you've never done this kind of work before."

"But I can't just stand here doing nothing, waiting. It's been such a long time already. We've been at the scene for almost half an hour."

"Yes, half an hour has passed, so all we can do now is continue to wait here. Grandpa has truly done his utmost to gather so many people this time. We've never previously conducted such a large-scale search for one person, do you understand?"

Speaking of this matter, it's indeed the truth, and Guo Hongyu grew up by grandpa's side, but to see grandpa conduct such a large-scale search for one person, this was truly a first in history.

After about 10 minutes, A'da really did it, then they saw several black trucks drive over from that side, and consequently, people jumped down one after another, holding shovels.

A'da ran up to the old master.

"Old master, I've really tried my best. Now there are 90 people who have arrived. The other 10 couldn't make it in time. If they rush over now, they might arrive after another 20 minutes or so."

"Alright, you've done what you could, and I also know that at this time, it's indeed very difficult to find workers. That said, this will have to do. Make good use of the time, everyone must find their own positions. Don't engage in futile efforts. Search carefully and dig bit by bit. If there are any signs of life, whoever it is, rescue them first, understood?"

"Okay, I understand."

With those words, A'da nodded and then ran off to the ruins to start directing the rescue work.

"Ah, there seems to be some noise coming from over here."

Suddenly, a worker then shouted out loud towards A'da.

At that moment, Li Fu and a few others heard it loud and clear, and they just exchanged glances before hurriedly rushing in the direction mentioned.

"Old master, take it easy."

Li Fu followed, then saw him stepping on the rubble. After all, he was getting on in years, so his walk was slightly unsteady.

"It's okay, what's important is the rescue. Let's hurry up and check out what this noise is about. It could really be Ye Chen down there?"

As they spoke, a few people circled around towards that direction.

Luckily, this stretch of road had already been cleared by them, so it wasn't too difficult to traverse.

"What's the situation? Someone just mentioned some noise. What did you see just now?"

"Just now, as I was sifting through this rubbish, I suddenly saw the soil below move a little bit. I thought my eyes were playing tricks, so I observed for a few more minutes. Then it moved again."

"Are you sure it's here?"

"Yes, it's right here. Look, look, it moved again."

Right at that moment, they suddenly saw the ground bulge forward.

But then the force quickly weakened.

It gave the impression that someone was pushing the layer of dirt from below, but they didn't have the strength to really move it.

After seeing all this, Li Fu just furrowed his brow and then placed his hands on that layer of dirt, earnestly trying to feel what was happening.

"Yes, there must be someone pushing this layer of dirt. Moreover, considering the current depth, anyone who can push it would have to be using very strong Inner Strength. I suspect that this person might be Ye Chen."

"Are you sure about that?"

"Yes, it should be the case. Remember how on the blueprint we saw that the depth underground reaches almost 20 meters? Normally, an ordinary person couldn't move it."

"So, you're saying that if Ye Chen can still push this layer of dirt under these circumstances, it proves that he must be trapped in some enclosed space?"

"Right. It means that this space is allowing Ye Chen to fit in for the moment, but if this goes on longer, it won't be viable."

"Alright, I understand. A'da, you know what to do, right?"

"Don't worry, I know what to do. Quick, bring over the excavator."

With those words, A'da called out in that direction and the excavator, which had been waiting on site for a long time, was already ready.

If they immediately used the excavator, they were worried about causing harm to innocent people, so they depended on manual labor. Only after the position was manually confirmed, the excavator would enter the scene immediately, making it easier to resolve the issue.

The excavator slowly came over and then began to excavate.

At this time, Ye Chen and Anying underground seemed to hear a rumbling sound from a machine above.

"Anying, Anying, am I hearing things? Did you hear the sound of machines from above?"

"I heard it. Just now I was wondering what that noise was. I thought it was just in my head, so I didn't mention it to you."

"If both of us can hear it, then does it prove that there are people above trying to dig this place, right?"

"Yes, that must be what it means. It looks like this time, this time we really have hope."

As they spoke, they just looked at each other.

They had been here for a full hour and a half, and the supply of oxygen they had for use was getting scarcer.

In another half hour or so, there would basically be no oxygen left in here, and by then, both of them would suffocate to death.

"I think I've hit something."

Just then, the excavator stopped, and the driver suddenly shouted out loud, and A'da just frowned and looked at him.

"What does that mean? What did you dig up?"

"It seems to be a very hard metal, and the excavator alone can't continue to dig through it. I also don't dare to destroy it forcibly."

"Hard metal?"

"Yes, hard metal."

"I understand now. The only metal we would use here are the ventilation and exchange ducts. I suspect now they both might have hidden inside this duct."
