"It's empty here, what valuable clues can we find?" Zhuo Yifan looked around at the empty beds, but he didn't find anything special, so he asked curiously.

If it was just these discoveries, Xie Dongting would not have called himself to this place in a hurry!

"I found an underground vault here. I don't know what's in it!" Xie Dongting pointed to a wall behind the bed and explained.

"Vault? Open it up and you'll know?" Zhuo Yifan was taken aback when he heard this, and then he came to the wall, and he saw a metal area on the wall.

"If I can open it casually, why am I so troublesome?" Xie Dongting said with a wry smile, take a closer look!

Zhuo Yifan couldn't help frowning when he heard the words, and looked carefully at the exposed metal wall.The exposed metal wall was only about one meter square.Surrounded by hard soil and stone piles, it is obvious that the volume is larger than what you see.

On this square metal area, there is a circular hollow with a gap in the middle, which can obviously be opened!But in addition to a valve, there are four rows of code input devices.Obviously, a combination safe!And it is four sets of 64-bit password insurance.If it is only to crack the code to open the valve, it may take some time to invite top cracking experts to come over!

"It's really difficult to open it. But the steel plate doesn't look very thick, can't it just be pierced through?" Zhuo Yifan asked curiously as he looked at the densely packed password keys.

"Of course it's not that simple. Have you seen the thin tubes around the valve?" Xie Dongting reminded.

Zhuo Yifan naturally saw a few rubber tubes connected to the valve, but he didn't know what these things were for, so he frowned and showed a puzzled expression.

"What are these things?" Zhuo Yifan touched those thin tubes with his hand, and found something greasy on the surface, so he couldn't help raising his eyebrows and asked aloud.

"It's an acidic protective film!" Xie Dongting explained.

"Acid protective film?" Zhuo Yifan looked confused.

"Simply put, there should be strong alkali in the pipes, otherwise the protective film would not be used to protect these pipes. This protective device is actually a destruction device. These pipes are filled with strong alkali, which has a strong Corrosive. If we use brute force to attack this safe, it is likely to cause these pipes to leak." Xie Dongting explained helplessly.

Hearing this, Zhuo Yifan immediately showed a dazed expression, nodded and said, "There must be some secrets in this safe, and these secrets can be corroded instantly by strong alkali! If it wasn't for his own people to open the safe through the password, the inside Things are likely to be destroyed by strong alkali, and we will not be given the chance to see the secrets inside!"

"That's right! Do you think it's so easy to open the safe now?" Zhuo Yifan nodded and asked with a wry smile.

"Okay, then what do you mean by calling me?" Zhuo Yifan asked with a sigh, frowning.

"I want to ask you, is there a way to open it! I haven't told anyone else about this place since I discovered it. You and I are the only ones who know it now. I haven't decided whether to report the situation, please ask a professional person Come and open the lock!" Xie Dongting nodded and explained.
