"The fire under us has been extinguished, we can go down and have a look!"

One by one, we followed the rope back to the playground. When I stepped on the ground where the flames had just been extinguished, I felt a burst of heat coming from the soles of my shoes.

As soon as we got to the ground, we found that Lu Chao did not completely blow up the exit with T NT explosives, because there was more than one stone gate set up at the exit. As far as we can see now, there are at least three stone gates blocking it. The first stone gate, which was nearly 40 centimeters thick, was blown up by explosives, and the second stone gate was partially damaged, revealing the third stone gate behind it, and the distance between the stone gates was about half a meter. And on the ground under the first stone gate, a large hole of more than one meter was blown out. It is this hole that sucks all the oil into it.

"Why can't you get full of so much oil?" Someone questioned.

"Yes, there is so much oil on fire, why can't you see the fire at all now? Is it that there is no oxygen in it? There is also speculation.

I think this cave is connected to some natural cave in the mountain, so you can't even see the shadow when so much oil flows into it.

Cao Fenghua did not check the stone gate with us, but took a few people to look for Lu Chao's body everywhere. But after going back and forth a few times, nothing was found, let alone Lu Chao's bones, even the bones of the two people he killed later were gone. I guess it was already burned by the fire.

Uncle Xu walked up to Cao Fenghua's side and patted him on the shoulder and said, "Xiao Lu may have gone when the explosion occurred, but this is actually very good...... At least it's better than burning in a fire or tormented by illness...... His parents have entrusted us with it, and he should have no regrets when he leaves......"

Cao Fenghua drooped his head and didn't speak, just nodded lightly. I heard that this Lu Chao was a soldier brought out by Cao Fenghua, and he has been following Cao Fenghua since he retired from the army, and his feelings are by no means ordinary.

When we came down, we did not continue to break down the stone gate and look for a way out, but rested on the spot. Calculate the time, fifteen hours have passed since morning, in order to ensure physical strength, Cao Fenghua and Lu Daxun suggested resting first, and then continue to move forward tomorrow.

After this day of exploration and escape, we are all so tired that our whole body seems to be about to collapse, and we can't stand up as soon as we lie down. When we came in, all the accommodation facilities were left outside, and now we can only lie directly on the ground. Even in this environment, no one complains about anything. Many people snore as soon as their bodies touch the ground.

"Poor ghost, have you slept?" The jar lay on the ground and asked in a whisper.

"Nope!" I replied.

"Do you think we're going to have something to gain this time?" Jar asked. I knew what the altar meant, so I replied, "Since I've seen the Haiwan clan here, I think this place should be related to Xu Fu." ”

"It's related, but what if we don't have what we want? How long can Xu Yunshu last? How long do we have left? Tanzi asked pessimistically.

“...... Leave it to fate, it is a day to be able to survive for a day......" I don't know how to answer this question.

The altar stopped for a while, and then asked me again: "You said that Cao Xuan's team came before us, looking at this posture, they should have also passed the level of frying and burning, how did they escape at that time?" ”

"Who knows~ Maybe the whole army is wiped out here, I can't say."

"You said that the stone gate in front and back here should not be a one-off, right? When Cao Xuan and the others came here, they must have fallen down, closed the door and beat the dogs......"

I "snapped" and hit the jar for a while: "Who do you say is the dog?" I have no opinion on you scolding Cao Xuan, don't scold and scold and bring yourself in. ”

"Hey, slip of the tongue, slip of the tongue!" The altar smiled and said, "You said that since the stone gate has fallen, why did we raise it again when we came?" And it works, don't you think it's weird? Could it be that someone has come here again and set up a new mechanism? ”

"This ...... I don't know much about ...... either."

At this time, Professor Jin's voice whispered on the other side: "Since the mechanism can be reset, it will definitely be powerful." ”

"The presence of force? So what power can there be in this mountain? ”

"There is no wind in this mountain, but there is water power!"

"Professor Jin, are you talking about the underground river?"

"There's no need for an underground river!" Professor Jin said, "Just drop water!" ”

"Water drops?" Tanzi and I asked in unison in surprise.

Professor Jin explained, "I think the mechanism here uses the principle of leverage. One end of the lever was chained to the boulder door, and the other end was supposed to be a huge bucket-shaped container filled with water, heavy enough to lift the door. If someone touches the trap, the coffin is hidden, and the drain trap in the bucket is also activated. When there is less water, the door panel will naturally fall. When all the water is drained, the drain mechanism slowly closes on its own, and then the water dripping from the top of the mountain will fill the bucket again little by little, pulling up the stone gate. And at the same time as the stone gate is raised, I guess that the coffin will also return to the city of Wanzhi under the influence of the machine. ”

"How long will that take?" Jar asked.

"It doesn't matter if it's a year and a half, or ten or eight years, it's an agency anyway!" Professor Jin said, "At least the owner lying in the coffin is not in a hurry. ”

"For such a long time, even if the offender is not burned to death, he will die of thirst and starvation, and by the time the door opens, the corpse will be left with bones......"

The next day, when we woke up, we looked at our watch and found that it was already eleven o'clock at noon. There were already a lot of people standing up, but no one called us. It seems that it is intended to give everyone a little more rest.

At twelve o'clock in the afternoon, everyone was called together to gather.

"After a night's rest, everyone was able to recover a little. Now, we have to go. After yesterday's fire, we have little drinking water left......" Lu Daxun said and licked his chapped and peeled lips, "So we must continue to move forward, find something to drink first, if we stay here any longer, the thirst will get worse and worse......"

Cao Fenghua and the others continued to use T NT to blow up the stone gate at the risk of the mountain collapse, and when they blew open the third sealed stone door, they found that there were two stone doors behind them, which only needed to be pushed to open.
