Although Lu Shan could be sure ... the back wall of the safe was finally corroded, but ... because the corrosion effect of this potion could not be so uniform every time, this pothole was pummeled for a long time, and there was a hole completely penetrated , But other positions are still worse.

Of course ... Lu Shan was not stupid enough to corrode the entire back wall of the safe. Initially, he wanted to etch a circle on it, but because the effect of the corrosive potion was scattered around, so In the end, he just eroded a ring the size of a car tire on the back wall.

When Lu Shan saw this, he took out the black dagger ... In this case, there was no need to spend money to exchange the corrosive potion, as long as he used the dagger to make a knife along the corroded ring, he would definitely be able to move the middle This alloy plate was cut off.

But ... at the thought of the fissures on the dagger, he hesitated again, thinking that it was too dangerous to use the dagger again at this time. Now he sighed, put away the dagger, and lifted his foot toward The safe was kicked **** the back wall.

"Uh-"

Lu Shan kicked up a few feet in succession, although he also made his whole body bone "click", but he also keenly felt that the wind passing through the metal wall was getting stronger, so he kicked more and more. Energize!

After kicking dozens of feet in a row, when Lu Shan felt that his right leg might have been broken, he finally heard the sound of "咣 当", the middle part of the ring on the thick metal wall, finally He was kicked out by the kick, and suddenly a fresh air rushed towards him ...

Lu Shan saw his spirits rise, but he was not in a hurry to drill in to see if there was really a way out, but just shot the back with a flashlight ... After seeing that there was a narrow passage inside the hole , Immediately turned back and walked out of the study.

Next, he had to wait for the poisonous smoke in the study room to dissipate, and then take the brother and sister of the Ning family out ... Although he was also very anxious and wanted to get a glimpse into the passage, he ... I ’m worried that after going out this channel, I ’m not sure if I will encounter any enemies or something like that ... If you let the brothers and sisters of Ning family stay here, it will be a bit dangerous.

After leaving the study and coming into the area where the poisonous smoke did not permeate, Lu Shan quickly checked his own health value, and saw that at this moment his health value had dropped to just over 300 points.

His defense ability is so strong that he has been eroded by poisonous smoke and lost more than 400 points of health. If Ning Feng is really with him ... I'm afraid that now Ning Feng has a few lives and he has to get in Already.

Lu Shan immediately took out two bottles of intermediate-level boutique life potions, and after drinking them both, his health was restored to full value without any doubt.

Next, Lu Shan found a towel and wiped off the pus and blood on his body. Then he found the brother and sister of the Ning family. Otherwise, he was afraid that the two would treat him as if It's zombies!

Hearing Lu Shan said that the metal wall of the safe had been penetrated, and ... there really was a passage behind, naturally the brothers and sisters of Ning family were ecstatic.

But now the poisonous smoke in that study is so pervasive, don't even think about leaving for a while, how can it be scattered for a few hours. So after a discussion, the three of them decided to go back to the lower floor first, anyway ... or make a meal first, eat and drink and talk about it.

After staying for about two hours, Lu Shan and others had enough to eat and drink, and then each of them put on a gas mask, and then put on several clothes on their own, and wrapped their necks, hands and feet. It was rigorous, so I climbed to the second floor together, and opened the door of the study ...

Sure enough, although more than two hours have passed, the poisonous smoke here was too thick until now. There is still a faint poisonous smoke covering it. If you want to wait for the poisonous smoke to completely dissipate, it is unlikely that it will be impossible in a day. Fortunately, a few of them are now wrapped in such thick clothes. Even if the poisonous smoke will erode the skin, it is not so fast. As long as they can go out quickly, they will not be affected much.

The hole that Lu Shan made in the back wall of the safe was enough for one person to drill through, but ... the edge of the metal wall was still very sharp, and it was easy to scratch a person's body if it was not possible.

As a special forces king, Ning Feng is okay ... but Ning Ke may not be able to do so, so Lu Shan had to pass by himself first, and then carried Ning Ke out of his place ... ...

The gangway behind the safe is very narrow, with a total width of only over 80 centimeters. If you are a very fat person, I'm afraid it's easy to get stuck in the middle of the road.

But the three of them have no difficulty walking in this passage, they just feel a little depressed. Winding up and down the corridor, I walked for about half an hour. The fresh mountain wind blowing in front of me felt the three people could not help but toss off all the heavy clothes on their bodies and speed up. Footsteps rushed out ...

When I came to the end of the passage, I saw a ray of sunshine coming from above, and it looks like it's daylight outside now!

There are several high stone steps at the end of this passage. One of the stone steps is covered with a large iron ring, and a rope is tied to the iron ring ... The rope should look very long, but at the moment it is coiled up. there. Further to the top is a few slab-like things pressing on top. Lu Shan jumped to the highest stone step in a few steps, and then lifted it hard ... The top slab had been pushed away. Already jumped out ...

Standing outside the passage, Lu Shan only found out that ... This place is almost at the top of the mountain, and this side is not in the direction of the mountain stream where a lot of poppies are planted, it should be in the back mountain position.

And it seems to be above a steep stone wall, with cliff walls almost vertical to the ground. There is only a small platform in the cliff wall outside the cave entrance. Lu Shan was standing here at this moment, and he almost felt that he could not reach the sky or the ground. Normally ... no one else will come to this place, and they want to leave from here ... It's not easy. But ... think of the large staircase of ropes on the stone steps below the cave entrance, Lu Shan immediately understood its purpose.

It seems ... When constructing this base, in order to open such a spare escape route, General Wu of that base also took great pains. But he never thought of it ... As a result, he was unknowingly touched inside the base, and twisted his neck in front of countless subordinates. This hidden escape channel was not used at all, but it gave Lu Shan a chance to escape from birth when they were trapped!
