Man Jianghong slowly woke up, sat up, and felt that his body was wet and cold, surrounded by overwhelming darkness, and he couldn't see his fingers.

He shook his head vigorously, pieced together his memories little by little, and finally remembered the Mid-Autumn Festival Gala, fighting, fleeing, thunder and anger, nine days of white light, and finally he and Bing Ling were forced off the cliff by Yuyangzi of the South China Sea Sect, and the huge impact of the sea made his eyes dark, and he didn't know anything.

So where is she now?

The environment was unknown, and he didn't dare to make any noise, and slowly crawled forward.

Amitabha, leave the place first.

There is soft sand underneath you, and there is a slight rippling sound of water behind you, is it on the beach? Why is there no ray of light?

Quietly crawling out of a distance of more than twenty meters, he turned over and sat up straight, examining his body.

Fortunately, my waist is not sore, my legs are not painful, my head is not dizzy, and it is estimated that I can go up to the fifth floor in one go. The clothes and pants are in good condition, a little damp, and the shoes and socks are gone.

He looked around slowly, and seemed to see a faint light.

Raising his head, he immediately froze.

I saw that it was far away, dotted with stars, and sparse spots of light were distributed in all directions in the sky. It is like the dim starlight of the sky in the dark night. It's like being in a big closed room, with some fireflies stuck to the walls and roof. You can clearly distinguish the dots of light, but you still can't see anything clearly.

He stared cross-legged and silently moved the eyes of heaven.

After a long while, he opened his eyes and vaguely saw some outlines of light and shadow, which turned out to be in an extremely empty large cave. The roof of the cave is dotted with low flowers in the east and west, emitting a faint phosphorescence. In front of him was a long, narrow lake, about 300 meters wide, but extremely long, winding its way at both ends, and I don't know which way it leads.

The cave dome is about two hundred meters high, and there is a thin layer of milky white gas floating in it, could it be the aura of heaven and earth? It feels a bit similar to the aura released by a master.

There are still many tiny invisible things flying and hovering in the cave, and they are extremely fast, but they dare not approach themselves.

After hundreds of thousands of years of evolution, the human eye has become a sophisticated detection instrument that automatically adjusts its resolution with the brightness and darkness of the light. This kind of function is available to everyone, and it belongs to the ordinary mode. Man Jianghong's Tianyan function is an advanced mode, which can see the vitality, true qi, aura and so on that ordinary people can't see. But every time he switches from normal mode to advanced mode, he always has to pay a little attention, just like when he first entered the research institute, he almost "killed" the sweeping aunt.

And now, in a treacherous and uncertain environment, the normal mode is finally perfectly integrated with the advanced mode, which can automatically adjust with the environment and can also move as you wish.

He stared at the dark lake in front of him, if a monster appeared, it was not easy to play, he had to stay away!

After walking about a hundred meters lightly, he touched the cliff face, which was covered with a layer of fluffy vegetation.

It should be mosses, or ferns, or maybe ancient life forms. The air here is fresh, like a mountain forest after rain, indicating that there are abundant negative oxygen ions. So, who is supplying carbon dioxide and who is converting it into oxygen?

His curiosity was aroused, he completely forgot about the situation and continued to think.

Photosynthesis cannot take place without light, and evolution should follow a completely different path from that of terrestrial plants. It is difficult for a single species to survive, so in this isolated space, there should be other animals and plants, or even higher life.

Thinking of this section, he couldn't help but be a little scared, and eagerly found a safe place to hide.

He groped his way against the cliff wall, and finally found a depression, more than two meters above the ground, and climbed up.

The environment is unknown and unpredictable, and the first rule of survival is to hide yourself and then try to act. This is the golden rule of the rivers and lakes that Zhu Fugui has admonished.

The cave was damp, the rocks were damp, and even the skin felt sticky.

He sat cross-legged for a while, gradually getting used to it, and his eyes could see more clearly.

Positioning is important!

The Eagle's Beak Cliff is the highest mountain around the Institute, which is very eye-catching, about three to four hundred meters above the sea. Freefall from such a height is a bit like ultra-high limit diving, how deep can you plunge into the water?

Gravitational potential energy is converted into kinetic energy and finally into fluid internal energy. According to the law of conservation of momentum and energy, as long as you know the viscosity of seawater, the cross-sectional area of the inlet water, you can find out how deep the water is by using the formulas of potential energy, kinetic energy and momentum, combined with Euler's equation and Bernoulli's equation.

He lacks the necessary data and can only make a simple analogy based on footage he has seen on television. If you jump from a 10-meter platform into the pool, about 2 meters, then if you jump from a height of 300 meters, you will enter the water about 60 meters.

Mid-Autumn Festival, the fifteenth day of the eighth month of the lunar calendar, the moon is the largest and roundest, and it is also the time when it is relatively close to the earth.

The tides of the ocean, rising with the movement of the moon. The morning is the tide, and the evening is the tide.

August 15 is often the day of the high tide. Thousands of years ago, Su Shi once described the tide of Qiantang as follows: "How high is the tide of the tide? ”

The institute is located in a bay surrounded by the Qiantang River, and the tides are not as exaggerated as the Qiantang River, but they still exist.

I remember that the oblique moon was past midnight, which should have been just after the early hours of the morning, which is the time when the sea began to rise.

Falling to the bottom of the sea at a depth of 60 meters, the rising water will push itself upwards to the shore.

If there is a cavity underneath the cliff, it will be poured into it.

In addition, the sea water here is connected to the outer ocean, and the air pressure is not particularly large, so it can be determined that the height of the lake is the sea level.

In other words, I am in the middle of a mountain. That is, under the eagle's beak cliff, four or five meters above sea level.

However, knowing this is useless!

Whether you can get out alive or not is the only criterion for judging ability.

After falling into the water and falling unconscious, the hand holding the ice spirit must have let go. In the vast sea, the probability of being poured into the same cave as her is not very high. Hope, though slim, remains.

Perhaps, she was lying on the wet sand as she had woken up before, unable to see her fingers, cold, hungry and frightened, helpless.

Thinking of this, there seemed to be a fire burning in the boy's chest.

He prayed to the gods and Buddhas in his heart, praying that the ice spirit would be safe. Even the father-in-law of the land, who loved to beat small reports, Man Jianghong, who was the most despised, sincerely apologized to him.

He groped his way down to the ground, and finally found two sharp stones, grasped them tightly in his hands, and searched the cave lightly.

I hope to see her for a while, and I don't want to see her for a while, and my own safety is left behind.

Hopefully she's floated up and back on land.

Even if you don't see you again, so what?

As long as she's good, that's fine.

The lake is surrounded by sandy beaches for fifty or sixty meters, and the closer you get to the cave wall, the more rocks there are. Most of them are round pebbles, but they are also mixed with sharp crushed stones.

He simply tore his shirt and tied both sleeves tightly around his feet.

Obediently in the middle of winter, this place is called heaven and earth, if you suffer some trauma and cause tetanus, it is not easy to play!

Walking quietly all the way, I didn't see any animals except that the damp part of the cave wall was covered with moss-like plants.

Very good, without small animals, there will be no ferocious predators.

No killing, no harm.
