When he asked me, I was a little confused. I didn't understand what he wanted to say at all. But I know brother donkey. He is like a qualified and annoying math teacher. He will never tell you the result of the equation directly. Instead, he has to explain the steps of solving the equation to you bit by bit. I can't listen if I want to. I can't hear what I want until he is happy.

"Remember, does it have anything to do with this picture? Don't tell me that this picture should be folded with that map. When you look at the sun, it is actually a treasure map?" I told brother donkey nonsense.

"No, no, do you remember, you pointed out several places to me on Lao Zhang's boat at that time, what did I say?" brother donkey began to play enlightening thinking again, so that I wanted to crush him, but I had to pull it off with him, otherwise I would spend more time arguing with him.

When he said this, I remember that there was such a dialogue at that time, referring to Tungus in Siberia and the southwest corner of Beijing. According to brother donkey, these places have had huge explosions in history. It happened in 1962 in Beijing and 1908 in Siberia.

"Why? There was some kind of explosion here?" I asked in wonder.

"This is far from an explosion in the general sense. It is one of the seven mysteries in the world. 65 million years ago, it was a thousand times more powerful than the Hiroshima atomic bomb, which led to the collective extinction of 75% of the creatures on the earth at that time. It was nicknamed the earth killer, and the center of the explosion was there." brother donkey said and pointed to the north, which is the direction of the Gulf of Mexico.

"You mean the big pit under the chicosulub?" several quick witted people said in unison. Brother donkey nodded to indicate that this was the answer, and then he said: "According to the seismic wave detection and the satellite, the crater has a diameter of nearly 200 kilometers. It is said to be caused by meteorite impact. Many scientists even attribute the extinction of dinosaurs here, but it is still controversial. However, the crater is more than 1000 meters underground, covered with hundreds of meters thick sedimentary rock. How did queen Yan get down?"

"More than 1000 meters is a fart. If you had followed brother earlier, you would have experienced several underground flights back and forth." I joked.

"Forget it, that thing, I don't want to sit for the second time in my life, so don't cheat people." Ivan recalled that experience and said with a little fear.

The sea snake pulled out the electronic map and marked out the location of the underground pit mentioned by brother donkey. We had to cross the whole peninsula to get there. Quinn immediately called a plane to pick us up. Po stayed here for a while, ready to wait for an opportunity to deal with kunba and informed Ares and others that according to his words, he united all forces that can be united. Although I think these people are always mysterious and a little uncomfortable Don't worry, but I believe Po won't suffer. Empress Yan is not here, and kunba's strength is below Po. Even if some vampires with soy sauce are added, it's estimated that Po won't be hurt.

We took a helicopter to the north of the peninsula. In order to avoid being found by the vampire forces in the jungle, we made a big circle. Finally, we landed about 30 kilometers away from a small town called chicosulub, because according to our analysis, if the Germans found an entrance, it must be in a sparsely populated place, not to mention there are many vertical caves and ground Water pulse network.

After landing, we immediately dispersed and launched a carpet search. We searched for more than 20 hours. Ivan called us on the radio to hurry up and said that brother donkey had found something.

Because Sanmei and I are far away from Lvge Ivan's group, when we rush there, most people have gathered. From a distance, we hear Lao hei and Lvge quarreling loudly, and Quinn and shopkeeper Qian are persuading.

"Stubborn donkey, you play with me and make a small broken fish. You say it's evidence. Believe it or not, I'll drown you in the water?"

"I didn't say they must go in from here. I just said there was a great possibility. We should go down and have a look." brother donkey didn't say it clearly, but he felt very sure in his tone.

"It's possible? Fuck? It's possible? I'm shaking my hands and strangle you. Do you want to calculate which of the two is more likely?" Lao Hei sounded very angry.

"I still think I'm more likely to say. You and I are not the only people here. If you want to strangle me, I guess they won't watch..." brother donkey said seriously.

"I... Ivan, don't hold me, let me go..." Lao Hei was so angry that he wanted to jump up.

I quickly separated the crowd and went up to ask what was going on. Brother donkey immediately handed me a strange dead fish in his hand when he saw me coming. I took it over and saw that it was about 4cm long. The whole body was pink white, the transparency of the body was very high, and the scales on the surface of the body were seriously faded. I could even see the blood vessels and internal organs under the translucent skin. There were four small whiskers on the head of the fish The appearance and beard should be a kind of catfish family, but the fish head has no eyes. It should be a natural degradation caused by living in dark water all year round.

"Tell me what you think." Sanmei looked at the fish in my hand, asked brother donkey, and made a quiet gesture to Lao Hei. Sanmei was the kind who didn't give orders to others, but someone would listen to the orders. Lao Hei immediately shut up.

"I've led a team to conduct several cave diving and made a lot of efforts in this field. Generally speaking, there are two kinds of cave fish. One is typical and the other is atypical. The typical cave fish is characterized by complete degradation of eyes and even disappearance of eyespots. The fish in the monkey's hand is called Lun's blind channel catfish, which is a typical cave fish. It generally lives in deep groundwater, No It will come to the place where there is light, so I think someone will pass through the cave below, startle them and cause migration, "brother donkey said, pointing to an open-air water cave not far away.

Let's go over and have a look. There are several same dead fish floating in the pool with a diameter of seven or eight meters. This well shaped pool connects the lower or vertical or inclined channels, and eventually leads to the underground water system. The whole peninsula is spongy limestone, and these water holes are the holes exposed on the top of the sponge. The locals also get water directly here, but never go swimming, because the following situation is too complex and the waterways are interconnected as intricate and changeable as fans. Some look very wide. Maybe they get stuck and can't turn around without swimming a few times. Some look very small and can only put down a bucket. Maybe there is a cavity larger than the basketball court below.

"What?" Quinn asked me, and I looked at him the same way.

Brother donkey saw us hesitate and added, "it's not just this one. I found this fish in several pools nearby."

"Why don't you send someone down to spy?" I asked Quinn tentatively. After all, they are all his men, and I can't direct them.

"Sea snake, take some brothers down and have a look. Don't go too far and make a mark." Quinn immediately ordered his best confidant. The sea snake happily agreed, unloaded his backpack and threw it to sol. He shouted to his teammates, "follow me if you've been in the Marine Corps." then he buttoned up his respirator and artificial gills, jumped into the water and disappeared silently. Several mercenaries from the Marine Corps also put down their backpacks, put on masks and followed into the water.

They went down to explore, and I waited anxiously on it. At this time, something that made me collapse happened. These mercenaries actually bet. Half of them bet on brother donkey and half on Lao Hei. The bet is "a romantic trip to Las Vegas". It sounds good. In fact, in the final analysis, they are not all "men's things" that eat, drink, whore and gamble. Provoked the disdain of Sanmei and Jinlihua, shook her head and cast disdainful eyes on them.

After half an hour, the water splashed below for a minute. The sea snake poked out his head, took off the respirator that was biting in his mouth and said, "the nerd is right. It's connected below. After a while downstream, it tilted upward. There's a platform out of the water. There are traces of people's activities in the waterway and on the plane, and it's recent."

"Oh yeah!!!" the people who bet on the donkey cheered, and the losers were a little annoyed. Lao Hei said with great righteousness: "what are you afraid of? I'll take all the losses."

"The black wolf is still the most loyal!"

"Black wolf, you're the most man, no one"

"Black wolf, I TMD love you"

"Then go and have a transsexual operation and marry him... Ha ha"

"Fuck you, it's also done by the black wolf. It just doesn't work well now..."

"Keep your voice down. He's in a bad mood and will bite..."

In the farting of a group of men, we put on our respirators, fixed our tactical flashlight on our helmets, jumped into the pool one by one, and swam deep behind the sea snake. Along the way, under the irradiation of the flashlight, we can see the marks drawn by the sea snake on the bedrock of the side wall with a special underwater marker pen. There is a layer of polarizing filter in our diving mirror. We can see those marks. We followed the big head down, passed a nearly vertical well shaped water hole like a chimney, tilted about 80 meters downstream, and began to hold the stone wall up.

The visibility in the water is much lower than that in the water, and many granular floating objects can be seen within the range of light. The head is full of inverted stalagmites and pillars. Some stalagmites can see traces of rope winding. It should be that someone fixed the guide rope on it. The sea snake pointed to the tips of several broken stalagmites to indicate that this is what he said. Before, there must have been people diving through, and a large number of people, all with heavy diving equipment.

After going upstream for a while, several bifurcations appeared on his head. The sea snake pointed to the rightmost one and motioned me to go in. He stayed at the fork to meet the people behind. I went in and swam a few meters before I saw the flashlight light of my brother waiting inside. With a crash, my head popped out of the water and was pulled up by several big hands.

The terrain here is slightly higher. It should be inside a hill not far from where we went into the water just now. Where the water just came out, the water level is level with the pool outside, but there is a platform of more than ten square meters above the water surface, which is covered with all kinds of stalagmites, the most of which are round dimensional, petal shaped and leaf shaped, which are not very common. There is water seepage in many places on the top of the head and ticking on the ground. It doesn't sound pleasant, on the contrary, it's a little gloomy and terrible. I'm not interested in the environment here. After brother donkey came up, I stared for a long time and took some photos.

On the other side of the platform, there are several other well shaped channels. The largest one is as big as a double bed and the smaller one is similar to a mahjong table. Due to the large number of channels and the small number of sea snakes who came in for the first time, there was no hurry. When we gathered on the platform, we continued to explore the way in groups.

Sanmei and I were small, so we chose a pool the size of a mahjong table to drill in. At first, it became narrower and narrower, and only one person could pass through the thinnest place, which made me feel like a small ant crawling in a sponge. After drilling through the narrowest place, the water channel began to become wider and wider like a trumpet.

But before I was happy, the situation began to become complicated, and there were several bifurcations in front of me
