I have a sea in ancient times

Chapter 266 Diving into the Seabed (1) Third Watch

The primitive people who were kicked off the boat screamed ghostly on the sea one by one, as if they had been greatly frightened.

Due to their instinctive fear of the sea, they were forced to "struggle" towards the shore.

Lu Hai carefully observed these primitive people who fell into the water on the boat.

Xiaobai, who was dressed in a maid outfit, massaged Lu Hai's calf intimately. Although the technique was still unfamiliar, it didn't matter, what mattered was the feeling.

Most of them are dog crawling postures, and occasionally one or two are quite special, and they will learn how to kick like a frog.

After deducting the "old, weak, sick, disabled and pregnant", a total of 30 people participated in this experiment. There were originally 31 people in total, but Lu Hai, who suffered from obsessive-compulsive disorder, simply canceled one person.

The performance of these 30 people is also very different. Some climb very fast, some can't climb at all, some are very flustered, and some are relatively calm.

Lu Hai spent two full hours repeating the action of throwing people into the sea.

Throwing them behind, these primitive people were already very self-aware, and before King Kong Barbie kicked them down, they went down by themselves with a plop.

Overall, the first round of bravery was quite successful. A total of 20 primitive people were selected to become the new generation of seafarers.

Actually, it was 22.

However, Lu Hai still picked up various problems and forcibly controlled the number of personnel to 20.

Next.

The 20 seamen will conduct the second round of gallbladder tests.

diving!

This is definitely more terrifying than swimming on the sea surface. You can only see the vast sea on the sea surface, and it is difficult to notice the marine life under the sea surface.

But diving is different.

Once you go down, you have to face all kinds of weird marine life. There was a time when Ma Odev dived in land and sea. To be honest, this thing is really not acceptable to everyone.

People with claustrophobia and deep sea phobia will really break down when they get down there.

Especially watching fish in the sea.

It's actually not that big, but it feels like it's magnified due to the effect of the diving goggles.

But before that.

Lu Hai intends to experiment first, the shark repellent bracelet and the shark repellant have the effect. Lu Hai took out a fresh fish and dripped the fish blood into the shark-infested sea area.

Sure enough, it didn't take long.

Several sharks were attracted and kept swimming around the fishing boat. After Lu Hai put down the shark repelling bracelet.

The shark responded immediately and then left the fishing boat. According to the young shopkeeper, sharks are animals that are sensitive to electromagnetic waves.

And this bracelet uses this feature to drive away sharks, and it's okay overall.

Lu Hai tried shark repellant again, which is a chemical substance, but it doesn't necessarily work on all sharks.

What Lu Hai is more worried about is the bull shark. This kind of shark is very curious and has a high attack power. If you are full and take a bite, if the bite bleeds, it will be a big deal.

Lu Hai tried them one by one.

Generally speaking, it is not bad. The combination of the shark repellent bracelet and the shark repellant will at least drive away the sharks in this sea area.

After ensuring safety.

Lu Hai made the first attempt and selected the first warrior, who was wearing the No. 6 uniform of the Lakers.

Let's call him No. 6 for now.

Lu Hai put on a diving suit and sunglasses for No. 6, and he was not in such a hurry to get him into the water, but let him get acquainted with the oxygen-inhaling environment first.

At the beginning, No. 6 inhaled very quickly, but after a short while, he developed a severe respiratory reaction, and Lu Hai quickly pulled off the mask on his face.

This kind of thing can only be done slowly.

There is no rush at all.

We could only let him get used to it slowly. After trying for about half an hour, primitive man No. 6 finally mastered the trick of using the breathing valve, and then Lu Hai put down the iron ladder.

Let the primitive man go down slowly. A yellow plastic tube is connected to his back. This is the oxygen delivery tube. It is inserted from the back of the clothes so that it is not easy to cause entanglement.

At the same time, Lu Hairang put down the underwater high-definition camera on Monday, so that he could simultaneously observe the physical condition of primitive man No. 6.

Just look at the behavior.

Just after No. 6 went down, he was quite frightened, and kept moving around, until he sank to the bottom, and then he relaxed a little, because Lu Hai tied a lot of iron pieces to him.

So he cannot float, but he can walk freely in the sea.

Facing this strange world, primitive man No. 6 was very curious and terrified. He went down for a full 2 ​​minutes without daring to move

After trying for about 5 minutes, he dared to let go of the ladder, and then his body began to sink slowly.

In the first attempt, Luhai was not in very deep water, but only five meters deep, judging from the images uploaded by the underwater camera.

The clarity of the bottom of the sea is still very high. At the moment when the No. 6 primitive man went down, all the surrounding sea fish scattered, but there were still many snails on the bottom of the sea, and there were also a lot of oysters and abalones.

In the video, Lu Hai also found a notorious snail, the concentric snail, which seemed to have just swallowed a sea fish, and now it looks like it has a long tongue.

In addition, Lu Hai accidentally discovered that there were one or two sea cucumbers near the place where the primitive man landed.

Lu Hai really hoped to find a white jade sea cucumber at the beginning, and then the fourth ring mission would end.

It's a pity that this kind of shit luck didn't seem to happen to him. On the contrary, what's worse is that there are not many sea cucumbers in this sea area.

Considering the rarity of the white jade sea cucumber, Lu Hai is a little skeptical, even if the sea area is searched, will there be a white jade sea cucumber.

Primitive man No. 6 was walking blindly in the water. Judging from his movements, he could clearly feel his fear, but the overall situation was good, and there was no struggle.

After almost 5 minutes.

Lu Hai pulled him up from the sea, and the first test was still very successful.

Then start to try 10 meters of water.

The distribution range of sea cucumbers is very wide, and sometimes they can be picked up in reef areas. It is said that there are sea cucumbers at a depth of more than 3000 meters, but the most suitable sea cucumber life seems to be in the range of 5 meters to 20 meters.

Different water pressures will have different effects on divers, and for divers, 10 meters is a hurdle.

If the sea level is a standard atmospheric pressure, then when the diver comes to the bottom of 10 meters, the pressure he will bear is exactly two atmospheres.

Although the diving suit has a certain effect, it is not as big as imagined. If there are old wounds on the body, it is very likely that it will be re-torn under this water pressure.

At the same time, it will cause vertigo symptoms, that is, the diver cannot control his body and feels dizzy. If vomiting occurs, it will be a very bad situation.
