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

Lu Shan's words really hurt their self-esteem … At that time, Ning Feng's old face turned slightly red, but... He also knew that what Lu Shan said was true. If he were to step out without caring about his safety, and if anything were to happen to him, Lu Shan would have to save him. Since that was the case, it was best to obediently listen to the arrangements.

Thinking about it, Ning Feng could only smile awkwardly, and quickly gave Lu Shan a gas mask, then ran over to find his sister.

Lu Shan's words were not really to scare Ning Feng, you must know … The Defensive Capability in Lu Shan's body was countless times stronger than Ning Feng, and now that he had been stimulated by the Toxic Smoke to the point that red patches appeared all over his body, if it was Ning Feng … That definitely wouldn't be as simple as a erythema. It might even be rotten to the bone by now!

Therefore, Lu Shan would definitely not allow Ning Feng to enter, otherwise … At that time, Ning Feng would be a skeleton's corpse. If he wanted to save, he would have to waste a lot of life potions!

Ning Feng naturally felt embarrassed to wait behind for Lu Shan to take the risk here, so he... If Lu Shan did not put more emphasis on the battle, even if Ning Feng knew that this Toxic Smoke was very powerful, and even might cause his face to be disfigured, he still might not be willing to retreat.

In fact, Lu Shan did not need to stay in the study room filled with Toxic Smoke. In any case, he had used three bottles of Corrosive Potion consecutively, and now, he had a rough understanding of the effects of this potion. Every time he smeared the potion on his face, he would immediately leave the study and tightly close the door.

This way... Unknowingly, Lu Shan had exchanged eight bottles of corrosive medicine, and smeared them all on the back wall of the safe. When he conveniently took out the ninth bottle … However, his heart suddenly skipped a beat, because even though he hadn't carefully calculated how much of the bank's balance was left, he still couldn't figure it out … He estimated that there definitely wouldn't be that many.

But now, he had exchanged for nine bottles in a row. Didn't that mean … Not only did the system store the money in his bank account, even his wealth in the real world could be taken away for him!

However, Lu Shan was relieved, after all he did not have much money left in his bank account, because he did not have a lot of cash left in his account. Even exchanging for another 100 bottles of Corrosive Potion would not be a problem, no matter how thick the wall behind the safe was, it would still be able to corrode a hole through him.

When the tenth bottle of corrosive medicine was used up, Lu Shan once again entered the study with the pungent Toxic Smoke that was so thick that he could not see anything, and dived into the safe. However, he suddenly felt a slight breeze blow past …

If it wasn't for the fact that a large area of the skin on Lu Shan's body had already started to fester, and a wisp of wind was blowing on his body, which made him feel double the pain, he probably wouldn't have discovered the existence of that breeze.

He was overjoyed. He quickly reached out his palm that was full of pus and blood and gently probed inside. Finally … When he moved closer to the bottom, he was finally sure... Indeed, there was a very minute breeze blowing in from this place.

This also meant that … Lu Shan had used ten bottles of [Metal Corrosion Potion] and finally managed to penetrate the thick metal wall.
