"Lake?" The fat man wondered: "This is a few hundred meters underground, how can there be a lake?" ”

I was also a little strange, but when I saw the lake painted on the scroll, I had all kinds of doubts in my heart, touched my head, and said, "Why don't we go down and have a look?" Since there is this lake on the scroll, let's go down and take a look, there may also be clues from Haotian. The fat man nodded.

Then, we put the rope down, and I tied the rope, and when I was about to go down, the fat man stopped me and said, "Wait, don't go down yet, we don't know what's down there, if there's any monster, then aren't you finished?" I'll start by putting a few waterproof light pieces. The fat man took out a few small square lights from his backpack, and the fat man twisted the lights in his hand, and the lights lit up, and the brightness was extremely high, which could completely illuminate the whole room, and then the fat man threw it down.

The light piece fell into the lake, because in the water, the light piece could not deliver its true strength, but it was enough, but we saw that the light piece kept falling until it disappeared into the darkness. The fat man glanced at me and said, "I'll go, this fucking lake is so deep?" It's a bottomless pit! I kept looking down and said, "Since it's okay down there, can we go down?" The fat man made an OK gesture, and then I jumped straight down.

"Hey! Qin Yu, be careful......" the fat man said.

"Don't be idle, come down." I shouted at it.

After a while, the fat man also tied the rope and jumped down. The fat man and I slowly put the rope, it was very dark underneath, there were about fifty meters on the surface of the lake, I looked at my watch, it was ten o'clock at night, and I didn't know how they were?

It was very easy, the fat man and I both fell into the lake smoothly, and the fat man was not good at water, so he may have choked when he first landed, and he kept coughing. I pulled the fat man to swim on the shore. After arriving at the shore, I patted the fat man, and the fat man spit out a mouthful of water and complained: "Damn, who did I offend the fat man, can you choke me?" Damn it. ”

I comforted the fat man for a moment, and then turned on my flashlight to look around. This seems to be a naturally formed underground lake, and stalactites, it seems that it has been hundreds of millions of years, the fat man came to the side of the stalactites as soon as he saw them, and immediately ran to the side of the stalactites, began to laugh lewdly, and whispered in his mouth: "Hahaha, what the fuck is really amazing, if you buy this stalactite, how much do you have to buy?" I glanced at the fat man and said, "I look at you, don't pay attention to that thing, stalactites are at the national protection level, don't say that you get one back, even if you get a gram, you have to enter the bureau." "The fat man glared at me, pouted and said: Lao Tzu didn't say anything about taking it out, he was amorous."

I still looked at this lake and found that there was no hole, which was artificially made from above, so there shouldn't be no hole? What's more, this is still hidden in an ancient tomb, presumably this lake is definitely not ordinary.

I looked at the fat man, and found that there was something wrong with the fat man, so I immediately ran to the fat man, only to see the fat man standing there motionless, at first I thought he had seen something good, but when I looked in the direction of the fat man, I was also stunned.

This... This is actually a huge mural, which depicts a huge lake on the top of the mountain, which is densely packed with people, and the people are embraced in the middle of it is actually King Zhou Mu and Queen Mother of the West!

I lay on the mural, the first thing that came to mind was the Yaochi feast, but the king of Zhou Mu and the Queen Mother of the West seen on this mural were very affectionate, why did I see King Zhou Mu and the Queen Mother of the West facing each other in that cave, I wiped my cold sweat and looked at the fat man on the side.

"It's... What's going on? Why is there a mural about the Queen Mother of the West. I was surprised.

The fat man shook his head and said, "Is this painting a feast in Yaochi?" ”

I nodded and said, "Why is it different from the mural we saw in the cave, this painting is obviously very affectionate, why do we see them in the cave facing each other." ”

The fat man touched his head and said, "But... Could it be that something happened to them? ”

I didn't speak, I didn't dare to think about it anymore, it seemed that the answer would only be at the end.

"Alright, fatty, let's find an exit." I said.

The fat man also moved, eagerly looking for an exit. But after searching for a long time, I still couldn't find it, so I sat on the ground with the fat man exhausted, took a sip of water, and said, "It seems that this exit is not around." The fat man came up and said, "You mean, this exit is underwater?" I looked at the fat man and nodded.

The fat man immediately ran to the lake, threw a stone into it, and then took out a tape measure from his backpack and inserted it into the water, and the fat man said in surprise: "Sure enough! The exit is at the bottom of the water, the bottom of the water seems to be a bottomless pit, no wonder the light I lost was not bright, it turned out to be falling into this bottomless pit. ”

I immediately got up, waded into the water, shone a flashlight, and said, "This... It seems to be hollowed out in the middle. ”

But the current problem is, we don't have wetsuits, we don't have oxygen tanks, how can we dive? We don't yet know how deep the bottom of the water is, and going blindly like this is the same as looking for death.

The fat man and I stared at each other with big eyes, helpless, sitting by the lake, looking at the middle of the lake, all kinds of melancholy, but the fat man didn't know what he was doing on the side.

I walked over to the fat man and saw that the fat man was using a big bucket and a straw, and I instantly understood, and said, "Fat man, I didn't expect you to be so smart." The fat man leaked a smug expression and said: "How powerful, this is a simple version of the oxygen tank, although I don't want the oxygen tank to last for a long time, but it is enough for us." ”

I looked at the fat man's wonderful little invention and said, "Fat man, don't you leak this thing?" ”

The fat man snatched back the oxygen tank and said, "Dare to question your fat grandfather?" You can rest assured, it's absolutely fine. ”

After a while, the fat man came over with two "oxygen tanks".

"Come, look at the oxygen tank made by your fat man." The fat man said.

I took it and looked at it, smiled, and didn't speak.

I strapped the oxygen tank to my body, put the tube in my mouth, and started to get into the water.

At first, it was okay, everything was normal, and the oxygen was enough, but after diving for a while, as the water pressure increased, my heart was almost unbearable, and I couldn't breathe, the fat man saw my strangeness, patted my back, and pulled me to continue swimming towards the water.

It was very dark underwater, which was undoubtedly a fatal wound for me, a person with underwater phobia, but I still fought for it.

We had been swimming for ten minutes, and the oxygen in our tank was obviously insufficient, and I began to have some difficulty breathing, and the fat man began to panic, but we had been diving for ten minutes, and it was impossible to go back, so I had to continue diving.

The fat man's breath is worse than mine, I can't do it anymore, the fat man saw me, so he pulled out the tube, he... He actually kissed me, and I quickly avoided it, thinking to myself, when is this? Is this kid having a spring? But it was too late, he pulled me over and kissed me directly on the mouth, my heart was nauseous, and I realized at this moment that he was giving me oxygen.

With the oxygen that the fat man gave me, I could still hold on for a while.

Soon, we saw that the light piece was still shining, and it was already there.

We looked left and right, and found a small hole on the left, and I gestured with the fat man, and I got in, but the hole was big enough for the fat man to get into, but if it was small, I really didn't know how to do it.

This seems to be an underground pipe, the water flow is very fast, I and the fat man were washed down, the fat man was in the middle of the pressure on me, I pushed the fat man off me, sucked a few big breaths of air, the fat man also woke up, looked back and forth, looked at me, and said: "How is it, you fat man I made this oxygen, not bad." ”

Maybe I was too tired, the fat man and I fell asleep quickly, but not long after sleeping, I vaguely heard a familiar voice, I opened my eyes with difficulty, and saw a familiar face in a daze, it was Haotian!
