The calm lake surface was disturbed, and the changes at the bottom of the lake can be imagined. The Bu family brothers were very satisfied, and Bu Yifan said: "Those strange bugs will definitely be moved."

After about 5 minutes, Bai Yi stopped: "Enough, let's go down and have a look."

With the experience and lessons learned from last time, Bai Yi and Qi Xie went down to the bottom of the lake very cautiously, making sure that the worm rock was no longer there, and then they surfaced and signaled everyone to go down. The Bu brothers still stayed on the shore this time, Naturally, the little fox was also. Although it was born in a snow mountain, it has absolutely no ability to handle water. The hairy man also stayed with them, and the others all dived into the bottom of the lake.

For Tang Sancheng, diving is an indelible pain. As soon as he dived into the bottom, Tang Sancheng held his breath and tried to reach the middle, and when he got closer to the rock layer, Tang Sancheng was immediately taken aback. These stones, what Bai Yi said He has also been to the 108th tower. These rock layers are exactly the same as that tower's stone, and even the stone patterns are the same. Unfortunately, he can't open his mouth now. He can only keep this in his heart and watch Bai Yi and Qixie fall to On the rocky layer, he bent down and groped hard on the rocky layer. Fu Yu and Shen Bing were both light, and seemed to be more relaxed underwater. The two assisted Qi Xie and Bai Yi, and slowly, Bai Yi's heart It is already somewhat clear that these rock formations are basically the top of a building, and the bottom of the lake is a building made of stones. To enter it, I am afraid that blasting will be required.

This time the entry into the water is over, Cong Yang is not here, they don't know anything about gunpowder, and the Bu brothers also don't know anything about explosives, so I'm afraid they have to find foreign aid at this time, but they really can't find a suitable candidate, so Bai Yi has to call Calling Cong Yang back, Cong Yang got a call, flew over immediately, and was sent here by the helicopter of the Bushi Group, and brought his guy with him. I haven't seen him these days. Cong Yang has gained a lot of weight, which made Shen Bing keep Joking that he was under middle age and gaining weight early, Cong Yang said angrily: "You people are really mean, how many calls have you made to me these days?"

"You live comfortably over there, and Qiaoer is pregnant, how can we call you back so easily?" Bai Yi said, "A lot of things happened during your absence. I know, there are still some things, I will tell you after this matter is dealt with."

What hasn't been explained is Bai Yi's current ability. Cong Yang has been carrying the toolbox in his hand: "Is the place very big?"

"Yeah, when you didn't come, we went into the water a few more times, and the size has been measured, and Xiao Shan has entered it into the computer, you can take a look." Bai Yi led Cong Yang into the tent, and Cong Yang said: "Looking at this is not enough. I want to go down and see the hardness of the rock. Is there a diving suit suitable for me?"

Cong Yang was about the same size as Xiao Shan, and went down after wearing Xiao Shan's diving suit, with Qixie protecting him. After some investigation, Cong Yang was already confident. He asked Bai Yi curiously while preparing the gunpowder. When people came these days, when they heard about the anaconda, they were already a little depressed. Cong Yang sighed after missing so many wonderful stories. The mood is gone.

"How is Qiao Er?" Fu Yu asked.

"The situation is very good." Cong Yang said: "Maybe it's because I want to be a mother. I am no longer as impulsive as before. I will distinguish the situation before lowering my head. To be honest, I am really relieved. I really envy Bai Yi." Well, even though my wife is a Gu girl, she won't worry about Fu Yu playing bad Gu on you, right? I was worried for a long time at the beginning."

It sounds pitiful and funny, especially since the mother-in-law is still a top-notch head-down master, the pressure can be imagined, but fortunately he has passed it safely, and Cong Yang finally prepared the gunpowder: "Okay, let's go into the water."

"Wait." Fu Yu expressed his worry: "We don't know the structure below, so it's really okay to explode like this?"

"This is easy." The Bu family brothers came in from nowhere, and Bu Yiban said: "We can dig a hole first, and use the surveillance probe to check the situation inside, just like what we did to the cave last time."

"Good idea." Cong Yang said, "It's a good idea to bring you here."

Bai Yi went down first, opened a small hole in the rock formation, and stretched out a very small probe. This kind of wireless probe has its own light source, but unfortunately it is not very clear, especially because of the influence of water waves. When the scene inside appears on the computer screen When going up, everyone just saw a blurry wall, Bai Yi asked: "Can the probe be rotated?"

"Not only can it be rotated, but it can also be stretched." After Bu Yifan finished speaking, he began to operate remotely. After the probe moved further, the blurry side gradually became clear. There were light and dark on it, which should be some patterns.

"It's rock paintings." Bai Yi finally came to a conclusion: "Rock paintings are history books depicted on cliff rocks. Generally, history books will record the historical events of the year, mainly focusing on the life of the royal family, while rock paintings are biased towards ordinary people. Ordinary people will pass The form of petroglyphs leaves the content you want to express on the rock wall. The method is very rough and untechnical. Compared with murals, the ornamental value is naturally inferior, but it is more mysterious. Rock paintings are composed of geometric shapes. These symbols express certain ideas in an abstract form, or record certain events. Among the many symbols and graphics, some graphics are relatively easy to understand, such as sun symbols, handprint symbols, footprint symbols, etc., and Some, but they have an inseparable relationship with religion, this pattern is very strange, it should not belong to Buddhism or Taoism, right?"

At this time, the petroglyph has been enlarged to the maximum, Tang Sancheng thought for a long time before saying: "It does not belong to Buddhism and Taoism, but this pattern is like a totem in a certain tribe, Fu Yu, what do you think?"

"There are similar patterns in the witch clan." Fu Yu said: "During the Shang Qin period, witches in some remote places would use such similar patterns when performing annual sacrifices. There seems to be a similar pattern on the inverted triangle. The two round objects look like bull's heads at first glance, but they are abstract bull's heads, which are very close to this pattern."

"This pattern is in the middle of the triangle, and it seems to have some content, but unfortunately, I can't see it clearly." Bai Yi said, "Okay, let's look at other places."

Turning his head around, Bu Yifan said, "This looks like a long passage, looking from here, it seems to have no end."

"That's right." Bai Yi became more and more interested: "I don't know where this passage will lead to. It is a very secret thing to build the passage under the lake. The map left by the red lady points here. Could it be Say she built this place? But it’s impossible. The project at the bottom of the lake is huge and requires a lot of manpower and material resources. All she has is the strength of the rebel army. If she built it by herself, it’s impossible not to alarm Chuang Wang and others. .”

"It may also be an ordinary person invited." Shen Bing said: "As long as you have money, you can do it, right?"

"No, judging from the rock paintings, it doesn't look like it was built by Hong Niangzi." Fu Yu said, "The rock paintings feel very ancient to me."

"Look again, can it be extended further?" Bai Yi asked.

"One meter at most." Bu Yifan said, and let the probe extend one meter forward, where the probe touched, the little fox screamed: "There is a dead person!"

Xiaohu saw it right. As soon as he stretched his probe, he saw several corpses lying in a haphazard manner in front of the passage. They overlapped one another and couldn't see their faces clearly. Judging from their figures, they should all be men. The place where these corpses are located There seems to be a hole in the place, and the picture ends here. Cong Yang said: "The inside is just a passage. The problem is, after the explosion, the water will rush in immediately, and it is entirely possible to submerge the inside. Although there is a diving suit, it can It is best to block that hole, I will only blow up the hole that only one person can enter and exit."

"This." Bu Yiban said, "It's easy. We have waterproof glue. If you don't need much, it can be used. I'll get it."

Bu Yifan was very interested in Cong Yang, because Cong Yang was confident that he would only blow up holes of the specified size, and they wanted to see if this young man who looked younger than them had the ability!

Now that the detection was completed, Cong Yang started to act immediately. He wrapped the explosives in oiled paper and carefully lowered them down. Compared with land blasting, underwater blasting has higher requirements for the selection of blasting materials. After submerged, it can detonate and maintain the power of explosives. Underwater blasting not only produces blasting vibration, impact vibration and ground vibration, but also produces safety impacts such as water shock waves and blasting surges, with higher risks.

"Actually, if you want to have a good effect, the explosives should be buried underwater for a few days, but time waits for no one." Cong Yang said while wearing a diving suit: "When you see the water surface change, immediately pull my waist the rope and get me back to shore quickly, you know?"

Cong Yang's expression had never been so severe, Bai Yi and Tang Sancheng nodded heavily: "Don't worry."

Cong Yang put on the diving suit and tied a long, long rope around his body, and then went into the water with the pack of explosives... Everyone couldn't see the underwater situation, they could only hold their breath and observe the changes in the water surface for about a quarter of an hour Afterwards, there were ripples on the water surface, and Tang Sancheng raised his heart: "Is it now?"

"How's the sound?" Bai Yi's throat tightened, and he swallowed vigorously: "Listen carefully!"

Tang Sancheng's ears perked up, he even closed his eyes, the sound of water, the sound of water, the sound of water began to change, Cong Yang was moving!He opened his eyes suddenly: "It's now, La!"
