The faint spot of light is five or six meters underwater, the cave is not big, but since the light can be refracted, I believe it should not be long, Yun Yanuan was reluctant to give up the 220 pistol, wrapped it in the deerskin belt, pinned the crew saber, jumped the shore, and plunged into the water vertically.

Ami Se also followed his example, took a deep breath, jumped high and stood up into the water, so as to minimize the resistance of the water and reach the depth of the water as quickly as possible.

Speed is very important here, because one breath does not hold for a long time, and the most amazing American magician, David Bryan, had a world record of a little over 17 minutes, but it is said that someone has already surpassed him in 22 minutes.

Ordinary people, people who swim and dive regularly, should be able to reach about five minutes, and those who are not trained will start to spit bubbles in about a minute or two, and finally choke on water.

Yun Ya warmed up to the position of the underwater cave, hurriedly twisted his waist, kicked his legs, changed direction, and swam towards the cave. Ami Se followed. It was dark underwater, and in order to make it easier to distinguish the location of the cave, Yun Ya Nuan deliberately put Candle Jiuyin's third eye in the deerskin belt.

The spots of light in the darkness are too eye-catching, even if it is a faint light. Yun Yanuan swam into the cave where light was refracted in, and it was so narrow that it was easy to touch the stone walls on either side with your arms outstretched.

This makes it easier for two people to move forward, and with their hands on the rock wall, they can go far ahead, much faster than swimming. But soon, the two of them realized that the hole was much longer than they thought, and the reason why the light was refracted was because the hole was straight.

The surrounding of the cave is circular, and there are obvious traces of chiseling, which proves that this is an underground waterway that is artificially chiseled, but the heart is not here, and Yunya Nuan can not judge the age and origin from the patterns on the rock wall.

Se Ami was already in an obvious state of hypoxia, her lips were purple, her cheeks were bulging high, and she was obviously going to be unable to hold it back, and sure enough, soon a string of bubbles came out of her mouth, Yun Yanuan always paid attention to her situation, and when she saw this, she hurriedly stopped, and when she came to her side, she hugged her waist.

Then he imprinted his lips on Se Yami's mouth, Yun Ya warmly practiced Neijiaquan, and Neijiaquan rarely practiced hard skills, basically practicing qi and nourishing qi, so he spent much more time holding his breath underwater than ordinary people.

While blocking Seami's mouth, he pinched her nose with one hand to prevent her from subconsciously inhaling with her nose due to lack of oxygen, causing her lungs to choke, which would be a big trouble.

Then, he slowly passed the air in his chest to Ami Se, relieving the pressure on her lungs, and his hands were occupied, and he had to use his feet apart and push forward both sides of the hole to increase his speed.

God opened his eyes, the hole was to the extreme, two people drilled out of the small hole, by buoyancy to drill out of the water, at this time the mouths of the two people have not been separated, as soon as the head is exposed, then each other opened their mouths big, like a bird to be fed, breathing the air hard.

Ami Se has collapsed, and Yun Yanuan is no better, but if it weren't for the sake of crossing Ami's gas, he would have crossed this waterway without much effort.

The water is very wide and the space is very large, it is an inverted hole, and there is a circular hole at the top, where the sunlight shines in.

This round hole doesn't look big, that's because the distance is too far, but in fact, this round hole Yun Yanuan guesses that it is almost dozens of meters in diameter.

"This? It's like a mountain has been hollowed out! Ami Se said, looking around.

"No, it's like a steamed bun-shaped mountain has been hollowed out, and besides, do you think the water is a little hot?" Yun Yanuan breathed enough air, and his body regained consciousness and said.

"Well, it's hot, even a little hot!" Ami Se said hurriedly.

Yun Yanuan looked at her exposed arm, which was already hot and a little red, and couldn't help but wonder in her heart, but then she understood, and said: "It seems that this is not an artificially hollowed out mountain, this is a volcano at all!" ”

Ami Se nodded in agreement.

The two of them were at the edge of the lake, looking at the middle of the lake, and couldn't help but be attracted by what was there, it was a huge tree, I don't know what kind of tree it was, and I couldn't see it too clearly from a distance.

But the fact that its canopy has reached beyond the crater is enough to shock people's hearts, it is at least a few hundred meters high, and it seems that there are many fruits growing on it.

"Let's go, the water temperature here is not stable, when the time comes, it will be miserable for the two of us to cook, let's go to the location of the big tree in the center of the lake, it is estimated that if we want to get out of here, we need to climb this real towering tree!"

Yun Yanuan swam forward first, and Ami Se followed, but soon the two of them didn't dare to swim, because the more they went to the center of the lake, the higher the water temperature, and the two of them didn't swim halfway through, they were already hot and painful, and in the past few meters, it was estimated that they would become shabu human flesh.

It's hard for two people.,You can't go forward and you can't go back.,To go back is to go back to find that monster desperately.,Advance is cooked.,Left and right are dead.,This is really no way to heaven and no way to enter the earth.。

The two men took a few steps back, stopping at a temperature their bodies could tolerate.

"This TM is going to kill the two of us! What a broken place, how the water temperature is not average! Yun Yanuan scolded.

"The center of the lake should be a real crater, then the temperature below is the highest and normal, according to this temperature increase, it is impossible for the two of us to get by, and the skin can be burned directly!" Ami Se shook her head, already a little desperate.

Yun Ya Nuan has already begun to think about going back to play with that monster, maybe there is still a glimmer of life, but Se Yami is thinking about whether to eat Yun Ya Nuan now, and then rush into the boiling water and turn into mud.

This is the power of nature, human beings with their own flesh mortal womb can not compete at all, the future must be a dead end, turn back and play with the invulnerable monster, that is also to die on the battlefield, not aggrieved.

This was Yun Yanuan's thoughts, but he also knew that the chance was slim, and even the chance of survival was close to zero, but it was much better than certain death.

So both of them put their hands on the knives on their waists and stroked them, one wanted to go back to find the monster to play for their lives, and the other was thinking about whether to eat Yun Ya Nuan.

Suddenly, Yun Yanuan seemed to think of something, looked at the round mountain lake, thought for a while and said: "This island is weird everywhere, but it is not separated from the five elements gossip, let's enter through a hole, then I estimate that there are eight entrances, let's go to other entrances to see, in case we can find food, there can be a glimmer of life." ”

Se Ami listened to Yun Yanuan's words, nodded hurriedly and said, "Okay, then let's go and find it, anyway, we will definitely not be able to go with Huxin!" ”

The two of them swam towards the lake again, and when they entered a very hot place and returned to the lake, they immediately felt cool and comfortable, and then began to look for other water outlets along the rocks of the lake.

The two of them dived down from time to time to see the situation below, so as not to miss the water mouth, so they turned far away, and they saw a water mouth, which was the same size as the hole where the two of them came before, which proved that Yun Ya Nuan's guess was correct, and the two of them were somewhat happy, after all, this also represented a glimmer of life.

Just as they were about to dive into the water hole, Yun Yanuan habitually glanced around, a habit he had developed for many years, but after this glance, he immediately froze in place, staring closely into the distance.

Ami called out to him twice, but there was no response, and she couldn't help but follow his gaze, only to see that there was a black dot on the surface of the lake that was slowly moving, and the direction of movement was the center of the lake......
