C532 Kung fu does not disappoint the painstaking (1/2)

After waiting for almost two minutes, the ”chi chi” sound inside the safe gradually stopped, but at this time the entire room was filled with a pungent smell, and even Ning Feng was unable to stay inside the room anymore. He had already run down to the lower level to look for a gas mask.

Lu Shan held his breath and went back into the safe, carefully inspecting the results of the corrosive potion, and could not help but be happy and worried.

What he was happy about was … This potion was indeed effective. In less than two minutes, a three centimeter deep hole that was the size of a bowl appeared on the hard alloy wall.

What made him even more worried was … This bottle of corrosive potion really wasn't much use. If he wanted to corrode a hole in the metal wall enough for a person to crawl through, who knows how many bottles he would need?

One bottle for 100,000, ten bottles for one million!

However, Lu Shan did not care about how much money he would spend right now. He was only worried that after the money in his bank card is deducted, what if … If the cash couldn't be repaid, then wouldn't he be blind?

However, right now, he did not have the time to think about it too much. In any case, he had to do whatever he could to corrode this wall … At most, if he could not exchange the corrosive potion later, then he would have to think of other ways. Even if he were to use the hammer and file slowly, he would be able to break through this metal wall no matter what.

Because this type of corrosive medicine, other than this time, he might not be able to use it again in the future, so Lu Shan did not go to exchange for too much at once.

When he smeared the third bottle of Corrosive Potion on the metal wall, Ning Feng finally returned with a few gas masks.

At this moment, there was basically no one in the room, and the room was filled with pungent smoke. This was because the ventilation system of the entire base was blocked. Although the air could still be slowly circulated, it was impossible to exhaust such a large amount of smoke.

Lu Shan relied on his dense Qi to take a deep breath, and after taking seven to eight minutes, he was completely fine. However … This pungent smoke was not only inhaled into his lungs, but even Lu Shan was unable to inhale a single bit of the Toxic Smoke. After such a long time, he who had been immersed in the smoke, gradually started to feel itchy all over his body. Lu Shan rolled up his sleeves and took a look, only to see that his arm was covered with a layer of red marks, which, upon looking at, would make people's scalps go numb. It was obvious that the smog caused by the vaporization of metal was no trivial matter. Even if one did not inhale it into their stomach, it was enough to kill them!

Seeing that Ning Feng was about to rush in wearing the gas mask, Lu Shan hurriedly dragged him out. After turning his head to close the door to the study room, he said to Ning Feng, ”Enough … I'll do it myself. The smoke is so toxic it's no use just wearing a gas mask. Stay away from A-Ke and you. Once the passage is open, I will call for you. ”

When Ning Feng heard how terrifying the smoke in the study was, he immediately said anxiously, ”Since this poison gas is so strong, I must exchange it with you! ”Otherwise, if something were to happen to you, then …”

Lu Shan glared at him fiercely and said, ”Don't worry … I don't think anything will happen to me. Instead, it's you... If he stayed here for too long, his skin would probably rot. Then when the time comes, you can tell me … Should I treat you or should I not? However … Don't I have to pay the price for curing you of these troublesome ailments? So … You and your sister, the two of you stay far away from me. As long as you don't let anything happen to yourself, that will be the greatest support for me … ”How about it?”
