After the four of them tossed around, it was close to midnight, the rain was very heavy, and the lake was white. It was no longer possible to return to the platform where the equipment was kept, so you had to spend the night in an old stockade on this cliff.

"Such an old village, will it be haunted at night! This place is gloomy and a bit cautious! Zhao Baixiong's heart was a little empty. No matter how big a monster he sees, this guy is not afraid, especially those things that cannot be seen or touched.

"The haunting has to live, it's raining so hard outside, the cliffs are wet and slippery, we don't bring so many tools, it's too dangerous at night, it can't rain here, just enough to sleep well, and tomorrow I'll be refreshed enough to go down to the lake to explore." Cattle fishing always seems very organized, and Ma Qian also supports the idea of cattle fishing. The four people rested on the spot, and they chose to live in the house on the top floor of the three-story house.

The four of them lived in two rooms and slept near the door, Ma Qian and Zhao Baixiong, and Zhao Qingmai and Lao Niu. Before going to sleep, several people expected all kinds of strange things to happen in the night, but nothing happened, except for the sound of rain outside the house, nothing else was heard. All four of them were so tired that they fell asleep in a short time.

In the early morning, Ma Qian was woken up by a rough shake, and when he opened his eyes, he saw that it was Zhao Baixiong, Ma Qian was very angry, and just wanted to scold Zhao Baixiong, but he saw Zhao Baixiong pointing out of the door with his hand, and then ran out quickly.

"What is this guy doing mysteriously?" Ma Qian was sore, and he also followed Zhao Baixiong out of the house, his feet were a little numb, and his speed was very slow. In a blink of an eye, Zhao Baixiong ran down the steps, and he didn't stop until he ran to the bottom of the house, where there was a small stone platform, close to the lake.

Ma Qian also rushed to the small platform below behind Zhao Baixiong. At this time, Lao Niu and Zhao Qingmai have been waiting here for a long time. On a small platform, the three of them stared intently at the middle of the lake, not knowing what attracted the three of them in the lake.

Lao Niu gave Ma Qian a place, this small platform was very small, and the four people stood on it a little cramped. After standing still, Ma Qian looked in the direction of the cow's finger, his heart tightened, and he was uncomfortable. I saw that in the middle of the lake, which was about 100 meters away from several people, the water was gurgling outward, and the water rushed out of the lake two meters high, and the diameter of the big water column was two meters. Are there whales underwater? Or some kind of big water monster, otherwise how did this water spew out?

"Ma Qian, have you thought of a place when you see this phenomenon?" Lao Niu pointed to the water jet spewing out of the lake and asked Ma Qian.

Ma Qian's heart moved, yes, this phenomenon is a little familiar, "It's the underground sea in the Toad Mountain of Changbai Mountain, this water column is very similar to the regular breathing of the underground sea."

Indeed, this phenomenon is the same as the underground sea of Toad Mountain, just now Lao Niu, Zhao Qingmai heard a certain sound in his sleep, so he followed the sound to find it, but found that the lake suddenly appeared blisters, the blisters were very large, one after another burst open, the lake surface was also in the form of inhalation, one by one, making a huge sound. This phenomenon lasted for about two minutes, and after Zhao Baixiong called Ma Qian over, the blisters disappeared, and then a huge column of water erupted from underwater.

Such a large blister and water column indicate that there is a large amount of gas under this lake, and the gas is discharged from the lake under the pressure of natural pressure.

If it weren't for a few people who had a similar experience, they would have thought that there were water monsters in the lake now, but now they are much more relieved, there is a lot of gas coming out of the ground, and there is no smell, which means that the gas emitted is not a dangerous gas such as methane, it is likely to be air. There is air in a place in the space under the lake, or there is a ventilation device, and when the air there gathers to a certain volume, it will be discharged from the lake through a certain mechanism or outlet, which is the strange phenomenon that everyone sees now.

There is space under the lake, and it is a huge space, and there may be a mechanism. Plus the origin of this lake is strange, isn't it?

"The P7 base is under the lake!" , This sentence was almost uttered by the four of them in unison, everyone wanted to look at it and smile, it seems that the hero sees the same thing, the base should be under this lake, and you can uncover this mystery by going down to the lake.

The water column on the surface of the lake disappeared, and the lake gradually returned to calm, and it took about four minutes from the appearance to the end of all these phenomena, and it was basically obvious that there was a huge space under the lake.

When they went down to the lake, they had to get their equipment back, and the four of them set off with them, climbed up the mountain rock, and slowly returned to the base where the equipment was stored along a passage that was easier to focus on in the middle of the cliff. This time, everyone took all their equipment and weapons and left the large platform below the waterfall, and it seemed that they had to set up their base in the stockade on the cliff, after all, there were houses there to protect them from the wind and rain.

Before leaving, Zhao Baixiong and Lao Niu went down to the lake again, which is still controlled by the flow of the waterfall, and groups of curly meat insects can still be seen on the water surface, floating one after another on the water surface. It appears that these strange creatures are waiting at the bottom of the waterfall for some living or dead animals to fall from the fall, and they are obviously hunting in a wait-and-see manner. And the downstream of this dammed lake, that is, where there are huge honeycombs and cliff villages, does not see the shadow of the meat curler, which can show that the meat curly worm is unlikely to leave the upstream, because the food is all upstream, and no insect will go downstream to wait, so there is nothing to wait, only the fate of starvation.

The four of them returned to the cliff village by the same route, and this time everyone basically figured out the topographical characteristics of this valley. The vegetation is abundant, and tall nanmu trees can be seen everywhere on the cliffs, and the huge root system is densely spread on the cliffs, mixing with weeds and rocks to form a complex terrain. There are many caves on the cliff, most of which are obscured by vines. Everyone analyzes that those tanuki who attack them at night must live in these cliffs and caves, and these ferocious creatures must rest during the day and come out to forage at night, maybe they are staring at everyone in the dark now!

Everyone set up their base in the fifth room on the second floor, Lao Niu and Zhao Qingmai skillfully distributed equipment for everyone, and everyone sorted things out while eating convenience food, which can effectively save time. Before entering the water, everyone made the weapon waterproof. After everything was packed, food, clothing and other items were left, and the four people set off with diving gear and weapons in their hands, aiming at the bottom of the lake.

Everyone has to look for the P7 base in the water, find the cause of this lake in the water, find the real reason why this lake can breathe in the water, and also find the clues of the cow grandpa Xingtuo under the bottom of the lake. The most excited is to fish for cattle, the main purpose of this trip refers to Xingtuo, about to reveal his grandfather's secret, it is normal to be a little excited about fishing.
