Hearing this, the green light became brighter and brighter in the darkness, and the sea snake still followed Lu Han, as if it was really stimulated by Lu Han.

Feeling the movement of the sea snake swimming, the corners of the mouth are slightly upturned.

"The intelligence of animals is really worrying."

Lu Han shook his head, withdrew his gaze from the sky, and threw himself into the surrounding seawater, observing it carefully.

Since the water depth is close to 100 meters, there is not a single ray of light in the sea, only some biological light flickering from time to time.

It is impossible to describe this darkness without seeing your fingers, and if it is daytime, the depth of the ocean is very clear, because of the presence of the sun, and now it is night. Microsoft's moonlight can't penetrate to this depth, which is why Sakura Shirayuki lets herself go into the sea during the day.

Listening to the sound of the sea, Lu Han felt the charm of the ocean for the first time, and his eyes gradually closed, this darkness could not see anything when he opened his eyes, but it would bring an illusion to the brain that there was no danger.

When Lu Han closed his eyes and lost his eyes to observe the world, his ears heard movements that he had not heard all along!

The sound of cutting through the sea water above him, it was the movement of the sea snake, the sound was perfectly hidden in the flowing seawater, and the faint sound was almost imperceptible, but after closing his eyes, Lu Han heard it.

Maybe this is the evolution of living things! When darkness comes all over the world, all living things either die or evolve to the point where they don't need light.

This is also the reason why the blind person's hearing is stronger than that of a normal person.

As the water pressure increases, the depth gradually decreases.

At the same time, Lu Han's brows furrowed slightly, he was a little strange.

I obviously feel that I should have exceeded 100 depths, but why is the sea snake still chasing after me? Did you sense it wrong?

When he opened his eyes and looked at the little green eyes, Lu Han was suddenly shocked in his heart, he had been mistaken! This place can't be confused with the outside world at all, maybe the sea snake from the outside world can only dive a hundred meters, but is this place still a hundred meters? Even from the outside world, who can be sure that there are no sea snakes below 1,000 meters?

Although he found that he might have made a mistake, Lu Han did not stop sinking, and he still did not give up.

What if it's a sea serpent's return to light?

However, this expectation was quickly shattered, and as time passed, Lu Han came to the bottom of the sea at a depth of 150 meters, looking at the green eyes in the sky, Lu Han's face showed a trace of helplessness.

"Still can't avoid this battle?"

Lu Han didn't want to fight with the sea snakes at all, but now Lu Han had no choice, although Lu Han could continue to dive, but looking at the state of these sea snakes, Lu Han felt that they were enough to hold on to the 300-meter position.

What a concept of 300 meters! One lap of the playground is only 400 meters! The pressure is enough to make people die, the limit of human diving is about 100 meters, if there is simple equipment, human beings can reach 200 to 300 meters, this depth must be professional divers, and a lot of preparation and diving preparation is required. Otherwise, there is a danger to life.

Although Lu Han has the confidence to dive to 300 meters, or even 400 meters! It was completely possible to get rid of the sea snake, but Lu Han didn't dare to continue!

The reason is simple, two words, oxygen!

Diving is easy and difficult to go up, and if the human body cannot adapt to the pressure change, it is easy to cause various problems. Returning too quickly from such a depth would lead to a lot of health risks, such as decompression sickness and excess nitrogen in the brain that can lead to nitrogen anesthesia and death.

Returning to the surface from a depth of 300 meters, even if you have this physical fitness, it takes at least 3 to 4 hours to decompress.

You can hold your breath normally for 4.5 hours, because strenuous exercise may only be about 2 hours, and oxygen is not enough at all!

Glancing at the dark sea around him, Lu Han felt a trace of remorse in his heart, he shouldn't dive, he should fight the sea snake to the death in the shallow water, and even run back to the kayak, but these two methods are too dangerous, after all, the speed of swimming is not as fast as the sea snake, and it is even much slower, so he chose to dive.

But the matter has come to this point, and Lu Han can only resist in such dark conditions!

Pulling out the triangular army thorn from his waist again, Lu Han silently slowed down the speed of his general, he didn't want to stop, but to pull in the distance from the sea snake, so that it could enter the attack range of his triangular army thorn. While you can attack them, you are still descending and will not be besieged.

The reason why this method was not used at the beginning was because Lu Han knew very well that this method could not achieve the ideal situation at all.

First of all, you attack the sea snake with your arm, the triangular army stabs are not knives, and there is a limit to the lethality of snake creatures.

Secondly, the body swing will affect the speed of sinking, after all, swinging the arm will increase the area of the body in contact with the seawater, which will increase the buoyancy of the seawater.

Suddenly, Lu Han was slightly stunned, and his face suddenly showed a look of annoyance, who said he didn't have a knife?

I didn't bring a camera with me, just to take advantage of the mall in case of danger. Anyway, you only need to use up the items in the mall and destroy the corpse, who can know?

But when danger really happens, Lu Han's thinking is very stuck in the situation where there is a camera.

Thinking of this, the sinking speed that had been slowing down became faster again, and he needed time to find a weapon. After all, there are too many things in the mall, and most of them are useless things. Of course, maybe it's just that you didn't find it working.

Hundreds of sea snakes originally saw that Lu Han had reduced their speed, and the entire group of snakes became excited. It's finally time to eat something delicious.

But soon the snakes were dumbfounded! Finding that Lu Han was speeding up again, they suddenly had a pair of small green eyes

Started with a hint of blood!

"Dare to fool us? It's such a bully! Can we sea snakes spare the beasts in front of us?! ”

"Can't! Meow,"

"No, huh!"

Looking for a weapon, Lu Han looked directly at the group of snakes, with a trace of astonishment on his face! The serpent has finally made a sound!

Lu Han quickly retracted his gaze and looked for a weapon again, after all, it is normal for animals to be able to send communication signals, although it is a bit tricky to translate into human language.

Looking at the same weapon on the screen, Lu Han quickly turned to the next page, and when he saw the types of weapons on this page, Lu Han cracked his mouth: "Little snake snake!" Hey, hey, hey. ”

Lu Han's voice sounded in the sea snake's mind, and for some reason the sea snake collectively shivered!

There was a hint of fear in the green eyes.
