Although he didn't know how thick the steel door was, Yang Jing was sure that it was definitely not an ordinary steel door that could serve as the gate of such an underground secret base. He couldn't say that this steel door could withstand a nuclear explosion, but its protection level was definitely not low.

The most important thing is that this door, which is comparable to a bank's underground vault, cannot be opened without a password and key.

Although there is still a lot of C4 in the storage space, using it in this environment is no different from seeking death. Besides, whether the power of C4 can blow open the door is another matter. Even if it can, I am afraid that the entire passage will collapse, which is no different from not blowing up the door.

what to do?

Yang Jing, who had never encountered such a difficult problem before, was completely at a loss at this moment.

Even though he has an IQ of 147, this kind of problem is not something that can be solved with IQ. To open this kind of door, both the key and the password are indispensable. Thanks to the influence of American blockbusters, Yang Jing even knows that if the wrong password is entered more than a certain number of times, the door like this that protects an important area will most likely be permanently locked.

As for the oxyacetylene welding gun in the storage space, it is even more useless here. This kind of door is definitely not something that can be solved by a mere oxyacetylene welding gun.

what to do?

Yang Jing sat down and slightly lifted the gas mask. He found that there was no peculiar smell in the air in the passage. Then he boldly took off the gas mask. Sweat immediately flowed down his cheeks.

As long as there is no harmful gas in the passage, there will be no problem at all. As for what is inside the steel door, with this steel door in place, even if a nuclear explosion occurs inside, radiation will not leak out.

He took out two bottles of iced mineral water from the space and drank them down in one gulp. Wearing a biochemical protective suit in this weather was even more sour than taking a sauna. If he didn't replenish some water, he would probably suffer from dehydration shock.

After drinking two bottles of ice-cold mineral water, Yang Jing felt like he was back to life. But when he saw the gate in front of him, his mood, which had just become a little happy, turned bad again.

After going through so much trouble to get here, and seeing the legendary treasure within reach, one would not expect to be completely blocked by an obstacle. No one would be happy.

But if he just turned around and left, Yang Jing would be very unwilling. Yang Jing was also the kind of person who liked to finish a task thoroughly. He hated the practice of giving up halfway the most. Not only did he hate others giving up halfway, he also hated and refused to give up halfway himself.

But no matter how much he hated giving up halfway, the steel door in front of him was a huge problem that Yang Jing could not solve.

In the end, Yang Jing could only sigh, stand up and prepare to walk out dejectedly.

However, the moment he turned around, his sight fell on the two empty bottles of "Wahaha" mineral water that he had just finished drinking. Almost subconsciously, Yang Jing bent down again and put the two mineral water bottles into the space.

This thing can't be left here, it will be a disaster if it is left here. The big rock outside has been moved away, and this passage will be discovered sooner or later. If someone finds out that there is China's unique "Wahaha" mineral water here, wouldn't it cause trouble for the country?

After walking out of the passage, Yang Jing narrowed his eyes when the sun shone outside. The hot air made Yang Jing start to take off the biochemical protective suit, but just as he was about to zip it up, a thought suddenly crossed his mind.

"Huh? Those two mineral water bottles just now..." At this moment, it seemed as if Yang Jing's reaction arc was extended a lot. When he put the two mineral water bottles into the storage space just now, he seemed to have overlooked a very important issue.

Yang Jing just stood at the entrance of the passage, thinking hard, completely unaware that the sweat from his body was almost filling up his sealed biochemical protective suit.

Suddenly, Yang Jing seemed to have come to an understanding. He slapped his forehead twice and muttered, "Storage space, damn storage space, how could I forget about this killer weapon?"

After reading this, Yang Jing's eyes lit up and his gaze fell directly on the half-broken stone.

After taking three or two steps to the front of the big stone, Yang Jing placed his left hand on the half of the big stone. The next moment, with a thought, the half of the big stone weighing more than ten tons suddenly disappeared, and in the storage space, there was an extra half of a big stone.

Yang Jing's mind moved again, and the big stone appeared in front of him again.

The next moment, Yang Jing thought: "Only take one third of the stone." As soon as this thought came to his mind, the half of the stone immediately became one third less, and the cross-section was smoother than glass.

In the storage space, there is one-third more stone, and the cross-section is also very smooth...
