There was a dull explosion that seemed to be right above the two of them, and as Li Xiaodong probed deeper along the pipeline in the bomb shelter, the cement structure above his head cracked, and rubble and earth poured down like quicksand.

Li Xiaodong hurriedly pulled Yumiko back, and was almost buried under the pile of mud and rock.

In the blink of an eye, seeing a small hole on the top that kept leaking mud and rocks, Li Xiaodong's heart shook and seemed to see a glimmer of life.

If you make an opening in the roof of the weak cave, you might be able to escape.

Li Xiaodong asked Yumiko to keep a safe distance, he broke a rusty water pipe himself, used the sharp end as a shovel for excavation, stepped on a broken iron table, and stabbed hard at the top hole of the quicksand.

"It's dangerous, you'd better stop. If you cause a large-scale collapse, you will be buried alive by a large number of earthworks......" Yumiko stood not far behind him and watched, she didn't want Li Xiaodong to take risks, of course, her heart was very conflicted, and she didn't want Li Xiaodong to succeed.

"There's no difference, even if you are buried alive, it's not much worse, anyway, being trapped here is death, the difference between dying two days early and dying a few days later......"

Li Xiaodong looked up at the top, holding the rusty iron pipe in both hands, and poked it hard at the top.

There was a loud noise, a large amount of mud and rocks tilted down again, and there was really a large-scale collapse on the top of his head, Li Xiaodong couldn't avoid it for a while, and was overturned by the flowing soil, and was almost buried in a mound more than half a person high.

At the same time, on the surface of the pothole here, a heavy crawler construction vehicle happened to pass through here to excavate and advance, only to hear a rumbling sound, the excavator suddenly shook the body, the left part of the traveling track actually crushed the ground, the body of the car tilted, actually fell into this piece of soft soil area.

"What's going on?" Seeing that the excavator suddenly rolled over and stopped in place, the right guard of the five doors hurriedly stepped forward and shouted.

"No, no, it's dangerous!"

On the excavator, the guard in charge of driving hurriedly pushed open the cockpit door, jumped off, and ran away in a panic.

With a pale face, he pointed to the crawler iron wheel that had sunk half of the excavator, and said with palpitations: "Major Youbei, you see, it should be the cause of the blasting, the surface seems to have cracked, and it can't withstand the heavy pressure of the excavator, and this ground is about to collapse." ”

The right guard of the five doors followed his direction, and for a moment, he frowned, touched his chin, and showed an expression of "a little troublesome".

It didn't take long for several thick towing ropes to hook the heavy vehicle in front of the dangerous vehicle, and one guard waved a small flag and whistled to direct another heavy excavator to slowly drag the dangerous vehicle out of the collapsed area with a roar of green smoke.

As soon as the crawler came up, there was a clattering sound, and the surface finally collapsed completely, revealing a crater-sized hole in the ground.

The right guard of the five gates led a few people to come up carefully, and seeing that the hole in the ground was already full of dirt like a small hill, one of the guards couldn't help but ask: "Major of the right guard, why is this happening? What is the structure under this ground, how can it be a hollow structure?"

"Hmm...... It should be a tunnel, I remember, my boss used to tell me that there was a World War II anti-aircraft fortification here, and in order to cope with the bombing of the American army, there was a large anti-aircraft bunker in this mountain. ”

The right guard of the five gates said a word, then turned his head to look at the other side of the mountain, pointed to that side and said: "I remember that the entrance of the cave is open on that side, it is very large, you can hide in a troop, and you can also drive in a car." ”

Everyone nodded, and one asked, "What should we do then?"

The right guard of the five gates said: "This can only be done, everyone hurry up and quickly bypass this dangerous area and go to the direction of the dammed lake." ”

In the next second, someone blew a shrill whistle, someone waved a small flag, and ordered the vehicle personnel to retreat and go around the jungle.

At this moment, in front of the right guard of the five gates, in the middle of the collapsed and mud-filled hole, a rusty mottled subway pipe poked out diagonally from the inside, revealing a sharp end, stretching and shrinking, and moving on its own, making the surrounding soil more loose, causing another mud and stone collapse.

"Look! what's that!?" a guard shouted in surprise, pointing to the rusty iron pipe that had suddenly emerged from the ground.

The right guard of the five gates also saw it, and couldn't help frowning a pair of thick eyebrows, and muttered, "What is this—What is this?"

"It's incredible, is there someone in the underground tunnel?"

In the next second, the rusty iron pipe made a clanging sound, as if someone was banging on the iron pipe with masonry at the end of the ground, as if it was transmitting some information.

Several people were puzzled, and they all got closer, and then they heard a faint, urn-sounding, and seemingly excited voice from the rusty iron pipe, which may be hollow:

"Hey! outside...... Who? Don't ...... ,...... Coming soon...... It's all collapsed......"

Hearing this voice, the five right guards and a group of subordinates looked at each other one by one.

A short time later, the rescue operation began.

Through the long iron pipe that could be faintly heard, the right guard of the five gates learned that His Royal Highness Yumiko, who had saved the Prince's Mansion family, defeated the Prince's Mansion party, and saved his own life, Mr. Li Xiaodong, were both trapped in this air defense fortification.

As for what caused the two of them to be trapped, Li Xiaodong didn't say much, and the right guards of the five doors naturally didn't have the time to ask more, the most urgent thing at the moment was to save people, and other things could only wait for the rescuers.

"Quick, pull a cordon, fence off this place, and no one will be allowed to enter. The geological hazards here are not possible to carry out any construction in order to avoid major landslides. You come with me to the front of the bomb shelter, bring explosives, and follow Mr. Xiaodong's instructions to go to the entrance of the cave to blast ......."

Under the command of the right guard of the five gates, a small team of engineers, a rumbling heavy vehicle, made a road through the jungle and headed to the other end of the mountain, in front of the entrance of the bomb shelter.

"Hehe, Yumiko baby, I'm really sorry, your family's love has come to the door of the five right guards, I won't die, you don't have to die, His Royal Highness's conspiracy to kill her husband seems to be going bankrupt......"

In the bomb shelter, Li Xiaodong was in a good mood, he picked up her white chin, smiled, and looked like a hooligan who was molesting a good family.

Yumiko looked at him with a complicated vision.
