The valve port at the stone door is close to the middle of the stone door, slightly to the left, of course, if you want to open the stone door, you have to turn this valve port.

Maybe Chen Xie was fascinated, and he didn't hear the fat man's shout for a while, "Chen Xie, in my opinion, we are going to make a fortune," the fat man next to him smiled obscenely, looking at his greedy appearance, he was willing to throw all the money on him. Chen Xie came back to his senses, but he became interested in the valve, and asked, "Why don't they turn the wheel?" Instead, he sighed and said, "Turn around, you can't turn at all, it's fixed to death." "Ahh Did you find the switch button before turning the wheel," Chen Xie wondered. "What kind of switch button, do you want to turn this wheel on and off," the horn asked busily.

Chen Xie nodded, and after that, the horn was really anxious, and got up and ran towards the valve mouth. "How do you know," the fat man on the side asked in a low voice, and helped Chen Xie up. Chen Xie didn't know how to answer, so he gestured to the fat man, the fat man was not a fool, he must know what Chen Xie meant, and he didn't say much to help him walk to the valve

Speaking of which, Chen Xie can be regarded as lucky. The injuries he suffered from the fall were not very serious, they were all minor injuries, but the skin was broken, and there were no other major cases.

When he came to the valve, he couldn't see the valve very clearly because of the distance just now. But what I see now is that this valve is actually a two-way valve, and the two-way valve is much more difficult to open. The two-way valve is composed of two runners, the size of the two runners is different, the diameter of the large is more than 5 times that of the small, and it is basically completely encased in it. For these, it is not surprising that people who understand valves, the question is how to open it is really nerve-wracking?

The direction of rotation of the two runners of the two-way valve must also be opposite, if it rotates in the same direction, then the air pressure in the valve will condense, and finally as the air pressure becomes larger and larger, it exceeds a certain space, and the big explosion comes

"Patriarch, what can I do," the number beside him was anxious, and the patriarch also looked at this valve carefully for a long time, and couldn't come up with a good solution for a while, "This is a two-way valve, it is more difficult to open, and these two runners seem to be fixed by something, and they can't rotate, it's a little difficult to do," Brother Scar had never seen this kind of thing, so he used the iron hammer in his hand to knock on the valve a few times, and the sound was very crisp, maybe this was because the wheel was made of bronze.

The fat man next to him came up with an ignorant solution, "Blow it up," "Nima, dead fat man, what's wrong with you, you won't take the wrong medicine, this is the valve, if you blow it up directly, we won't be finished directly," the horn scolded angrily. Of course, the idea of a fat man is really unexpected.

"So what should we do now, we won't just sit like this, or let's try this valve again, maybe we can turn it now," Xiao Jian beside him also spoke. Patriarch, seeing this, he couldn't think of any other way for a while, so he could only do it again. This time, he called two of his men to be strong, and instructed them both to turn the valve at the same time, and if they could turn it, they must quickly hide on both sides of the stone gate, because when the valve is opened, a strong air flow will rush out directly, and if it is powerful, it can smash people.

The two big men also understood what he meant, but the patriarch was very worried, always feeling that something might happen, and in desperation, he walked to the side of the stone gate, "Trust them, it will be fine," the white-haired old man beside him comforted. Although the patriarch accepted it on the surface, it was not like this from his heart

After the whole thing was done, everyone hid on both sides of the stone gate, and only two strong men were left at the valve, and the two of them each exhaled, foamed at the mouth with both hands, and then clenched the wheel after a few movements. Immediately afterwards, they began to launch a force, unexpectedly the wheel actually turned, the two big men gritted their teeth and used all their strength, and finally turned the two wheels to the terminal, at this time, the valve was also opened, and a burst of white gas came out of the stone door, and a warm current also swept over in an instant

The patriarch, seeing this, hurriedly shouted, "Get out of the way!" However, it was too late, it was only a slight opening at the stone gate, but as the white gas continued to pour out, suddenly, with an earth-shattering loud noise, the stone gate was completely washed away, and a strong air pressure came suddenly, scaring the others to the side of the stone gate, closing their eyes and nesting on the stone wall.

The surge was so huge that it instantly swept away the two elite men, and the shouts followed, and there was no movement after that

When they all opened their eyes and looked at the stone gate, all this changed, the stone gate was long gone, only a hole was left, the height of the cave was still about 1.3 meters high, and the shattering of the stone gate might be the powerful surge just now

"Patriarch, what about the two big men?" The trumpet asked. "Hey—they may have been washed away by that pressure," the white-haired old man sighed, feeling very depressed. "Nima, this powerful thrust is really powerful," the horn praised again and again.

The patriarch said in a low voice, "There must be a pressure in this valve, and the power of this pressure is enough to smash people, as for where does that pressure come from?" The patriarch pondered, and looked at the hole again.

That hole is the stone gate just now, and now the stone gate doesn't know where it has been washed away, not to mention, this is really weird, let this strong air pressure, why didn't the earth wall around the stone gate collapse down, this is indeed a deep thought?

This man is much bolder than before, he has already looked into the hole, almost blinded his eyes, "Damn, there is some smoke in this hole," "Look, there is water in this ground, why is the water hot," the fat man also became puzzled, and touched the water flow underground. Looking in this direction, the water just happened to flow out of the hole, "Mom, we can go in and do it," the horn became anxious, and picked up a steel gun and wanted to rush into it to do a big job. "Don't! Don't be in such a hurry," the patriarch pulled the trumpet back.

"I think we are probably in the watery area," explained the patriarch, "and that's strange, why is there heat, is there a hot spring in it," guessed the fat man. The patriarch shook his head instead, "Maybe not, maybe this is a water house, which was used by the ancients when they built ancient tombs," and for a moment, the others were frightened
