Bo Xinwen analyzed: "It's very possible. The Netherworld Envoy once said that they knew about the GPS positioning chip embedded in the remains of the ancient tomb early on, so they used the chip to deliberately lure us here. Then they trapped us all to death. But he Why did they choose to trap us in the cave where the female demon was sealed? I think it is because they know that if we want to leave the cave, we must break the seal. And they feel that there are many strange people among us. Maybe there is a way to break the seal. Then the female demon will be able to escape from the seal. And even if we can't break it, if we can be trapped inside, it can be regarded as getting rid of their henchmen."
Yu Fei added on the side: "This can also explain why the Nether Envoy immediately brought three black dragons to help the battle as soon as the female demon came out. It's because they had already made preparations to respond."
"If this female demon recovers her skills, I'm afraid she will be in big trouble." Kun Yuanzi said with concern.
"Let's get out of here first. We can discuss anything later after we get out. This place is so damn cold." The cold wind was still blowing by the Yin Lake. Ding Laosan couldn't bear it anymore.
Bo Xinwen nodded: "Third Master is right. Let's talk about it after we get out."
To leave here, we have to go through a maze-like cave. We still have to let Bai Yiqing lead the way. The group of people followed her and walked out cautiously.
Originally, they thought that they might encounter the terrifying group of white beetles again in the cave. Everyone was prepared to deal with it. Especially Mr. Ye, who held the Xuantian Mirror firmly in his chest. This thing was great for dealing with white beetles. A great weapon of the beetle.
However, nothing unusual happened along the way. Not long after, the group arrived at the circular staircase they had descended from before.
"Why is this road so quiet? How could the people in the cult let us go so easily?" Bo Xinwen thought to himself. He always felt a little uneasy, but he couldn't tell what was wrong.
Everyone walked up the stairs until they reached the end. Only then did they realize that the exit had been completely blocked by an adobe wall.
Kun Yuanzi stepped forward and pushed hard, but there was no reaction at all.
"Sir, please don't bother yourself. There's a big building up here. It's not that easy to push away."
When Bai Yiqing said this, everyone remembered that the exit mechanism was an entire ancient building. When the ancient building sank into the desert, the exit was closed. It only opened when it rose up. Now the ancient building must be sunk in the desert. So the exit is naturally closed.
"There must be an opening mechanism that can open this exit." Kun Yuanzi said. He took out the pendant given by Hou Qing on his chest. When they came in, they relied on this pendant to open the mechanism. The whole ancient building rose.
Kun Yuanzi stepped forward and saw at a glance that there was a large flat circular depression on the big stone blocking the passage. The surface of the stone in this depression looked much newer than other places. It could be judged from this. This depression should not have been formed for long. He couldn't help but frown: "It seems that something was originally placed here, but it was dug away. Maybe it was the mechanism that opened the passage."
Yu Fei was startled: "Taoist Master, you are saying that the ghosts have destroyed the opening mechanism and want to trap us in it."
"Damn it. It turns out that these guys have such skills. They are really despicable."
"Does Taoist Master have any other way to open this mechanism?" Bo Xinwen asked.
Kun Yuanzi shook his head: "If the opening mechanism is destroyed, then the entire building will become a dead object. It cannot be opened again unless it is forced to break through."
"Force a breakthrough. Or let's try it with a bomb." Tieniu said from the side. He was a demolitionist. His bag contained a lot of plastic explosives specially used to open holes.
"What do you think, Master San?" Bo Xinwen turned to ask Ding Laosan. After all, he is an expert in exploring caves and finding gold, with rich practical experience. Although if we just talk about his familiarity with explosives, he may not be as good as Tieniu. But he said When it comes to opening holes, he still has the most say.
Ding Laosan stepped forward and carefully inspected the earth wall in front of him. After pondering for a while, he said: "It's not impossible to use explosives. But it can't be blown up directly. After all, the ancient building above sunk into the desert and there are four Five meters. Such a deep distance. Even if we use explosives to blow up these bricks, the bricks above will continue to pile up. So we have to dig a small hole straight up to the ground first, and then bury the bomb in the hole. Blow it up. This way you can make a hole and crawl out."
When Ding Laosan took Lao Guitou and others to explore caves to find gold, they always used this method to open robbery caves. As long as they don't encounter hard rock layers, it basically works. However, robbery caves are generally Drill from top to bottom. But this time, we have to drill from bottom to top. And when digging holes, we always look for the softest soil layer. But this time, we have to drill holes in relatively hard mud bricks. Although the principle seems to be the same. Almost. But the difficulty is relatively much higher.
Of course, this problem would not trouble them. Ding Laosan asked Lao Guitou to take out a rather strange-shaped device from his bag.
This is a portable well drilling machine. It is specially used for drilling wells. It uses diesel as power. As long as there is a long enough drill pipe and diesel, it can drill to a depth of more than 100 meters. Ding Laosan found someone to improve it. .It is specially used to excavate robbery holes.
The improved well-drilling machine weighs about twelve or three kilograms. It is not light to carry on the body. And although it is said to be portable, it is only compared to a large-sized well-drilling machine. In fact, it is not small. Old Guitou originally did not want to But Ding Laosan felt that he was well prepared, so he forced the old ghost to carry him on his back.
Fortunately, Lao Guitou's backpack is waterproof. Otherwise, when they swam in the Yin Lake before, this thing would have been scrapped long ago.
Of course, it is still difficult for this well-drilling machine to penetrate thick rocks. Therefore, when they were trapped in the depths of the cave more than thirty meters deep, this thing was basically of no use. But it will be after all. It's just a mud brick. Drilling holes with it shouldn't be a big problem.
Old Guitou connected the well drilling machine to the drill pipe and began to work.
Following a continuous mechanical roar, the drill pipe drilled into the earth bricks very easily.
Lao Guitou and Ding Hao took turns and worked for almost two hours. Just when the diesel was almost exhausted, the hole leading to the ground was finally drilled.
Both of them were extremely tired and collapsed on the ground.
