C533 Escape day

Although Lu Shan could be sure … The back wall of the safe was finally corroded, but … Because the corrosion effect of the potion wasn't as uniform, the potholes on the pothole continued for a long time. One part of the pothole was completely pierced, but the other parts were still missing.

Of course … Lu Shan was not stupid enough to want to corrode the entire back wall of the safe. Initially, he wanted to corrode a circle on top of it, but because the corrosive medicine had scattered everywhere, in the end, he could only corrode a ring the size of a car tire.

Seeing that, Lu Shan immediately took out his black dagger … In this situation, there was no need to spend money to exchange for corrosive potions. As long as he used his dagger to cut down the corroded ring, he would definitely be able to cut off the alloy plate in the middle of the ring.

However … When he thought of the cracks on the dagger, he hesitated for a moment. He felt that using the dagger now was too dangerous. He sighed lightly and put the dagger away, then lifted his foot to kick against the back wall of the safe.

"Dong, dong, dong ~ ~ ~"

Lu Shan kicked it a few times. Although he was also shocked to the point that all the bones in his body creaked, he was acutely aware that the wind that was blowing through the metal wall was becoming stronger and stronger.

After kicking it dozens of times, just when Lu Shan felt that his right leg might have already broken a bone, he finally heard a "bang" sound. The middle part of the ring on the thick metal wall was finally kicked away by him, and a gust of fresh air assaulted his face.

Seeing that, Lu Shan's spirit was raised, but he was not in a rush to rush in and see if there was really a way out, he only used his flashlight to shine on the back. Seeing that the cave entrance was indeed a narrow passage, he immediately turned around and walked out of the study.

Next, he would have to wait for the Toxic Smoke in the study to disperse before he could bring Ning Siblings out … Even though he was also very anxious and wanted to enter the passageway to see what was inside, however … However, he was worried that if he followed this passage out, he might run into another enemy or something. If that happened … If he let Ning Siblings stay here, it would be a bit dangerous.

After leaving the study and arriving at the area where the Toxic Smoke did not spread to, Lu Shan immediately checked his HP. He saw that his HP had already dropped to around three hundred points.

His Defensive Capability was so strong, yet it had already been corroded by the Toxic Smoke to the point of losing over 400 HP. Even if Ning Feng had a few more lives, he would still lose them all.

Lu Shan immediately took out two Intermediate Health Potions. After drinking it all in two gulps, his HP returned to its peak state without any suspense.

After that, Lu Shan found a towel and wiped off the blood and pus on his body. Only then did he go over to Ning Siblings … Otherwise, if he went directly over there, he would have to be afraid that those two people would treat him as a zombie!

Lu Shan had said that the metal wall of the safe had been broken through, and … There was indeed a passage at the back, so the Ning Siblings was naturally overjoyed.

But now, the study room was filled with Toxic Smoke. He could forget about leaving for the time being, as it would take at least a few hours to get there. Thus, after a short discussion, the three decided to return to the lower level. No matter what … He decided to make a meal first and eat until his stomach was full.

After waiting for around two hours, Lu Shan and the others finished their meal and drank their fill. After that, each of them wore a gas mask, and each of them wore several sets of clothes on their bodies. They wrapped their necks and limbs tightly, then climbed up to the second floor and opened the door to the study …

As expected, even though it had been more than two hours, the Toxic Smoke here were too dense and there were still faint Toxic Smoke inside. It would probably take at least a day for all the Toxic Smoke to completely disperse. Fortunately, they were all wrapped in such a thick layer of clothes, so even if the Toxic Smoke eroded their skin, it wouldn't be that fast. As long as they could get out quickly, they wouldn't be affected much.

The hole Lu Shan created on the back wall of the safe was more than enough for one person to go through, but … The edges of the metal wall were still very sharp. If things went wrong, it could easily scratch a person's body.

As a special forces king, Ning Feng was fine … However, Ning Ke might not be able to do it anymore, so he had to go over first. After that, he followed Ning Feng and carried Ning Ke out horizontally …

The passageway behind the safe was very narrow, with a width of only 80 centimeters. If this person was especially fat, he would probably be stuck in the middle of the path.

However, it was not difficult for the three of them to walk through this passage as they only felt a little pressured. They zigzagged up the tunnel and walked for about half an hour before they felt gusts of fresh mountain wind blowing by. The three of them couldn't help but shake off the heavy clothes on their bodies. Then, they sped up their pace and rushed out …

When they arrived at the end of the tunnel, they saw a ray of sunlight shining through. It seemed that it was daytime outside!

At the end of this passage are some tall stone steps. On one of these steps is a large iron ring with a rope attached to it." The rope should have seemed very long, but now it was coiled and placed there. Above them were a few stone slabs that were pressed against the ceiling. Lu Shan took a few steps forward and jumped onto the highest stone steps. Then, he forcefully lifted them … The stone slab above him was pushed aside, and with a leap, he leaped out …

Standing outside the passage, Lu Shan realized … They were almost at the top of the mountain, and this place was not directly facing the valley where a large amount of poppies were planted. It should be at the back of the mountain.

Moreover, this place appeared to be on top of a precipitous cliff. The top and bottom of the cliff seemed to be perpendicular to the ground. Only the outside of the cave entrance had a small platform that was caved in within the cliff. At this moment, Lu Shan stood there with a feeling of not being able to reach the sky or even reach the ground. Under normal circumstances... No matter what others would never come to this place, and they wanted to leave this place … It was not a simple matter. However … Thinking about the big plate of rope on the stone steps below the cave, Lu Shan immediately understood its use.

It seemed like … When they were building this base, for the sake of opening up a backup escape route, the General Wu in the base had put in a lot of effort. However, he had never thought that … In the end, he had been sneaked into the base by someone without anyone noticing and had his neck twisted off in front of so many subordinates. This hidden escape passage was completely useless. Instead, it allowed Lu Shan and the others to have a chance to escape if they were trapped!
