The primitive people who were kicked off the ship were screaming on the sea, as if they were greatly frightened.

Due to their fear of the instinct of the sea, they forced them to "struggle" towards the shore.

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

Xiaobai, wearing a maid outfit, massaged Lu Hai's calves very thoughtfully. Although the techniques were still very unfamiliar, this was not important, what was important was that feeling.

Most of them are in the posture of dog crawling, and occasionally one or two are special, and they actually learn from frogs to stomp.

After deducting the "old, weak, sick, disabled, and pregnant", there were a total of 30 people participating in this trial, with a total of 31 people. However, Lu Hai, who suffered from obsessive-compulsive disorder, simply cancelled one person.

There are also big differences in the performance of these 30 people. Some climb very quickly, some cannot climb completely, some show panic, and some are relatively calm.

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

Throwing it behind, these primitive people were already very conscious. Before King Kong and Barbie could kick them down, they went down by themselves with a thud.

Overall, the first round of gallbladder tests was quite successful, with a total of 20 primitive people being selected to become the new generation of seafarers.

Actually, there are 22.

However, Lu Hai still found various problems and forced the personnel to be controlled to 20.

Next.

These 20 seafarers conducted a second round of gallbladder tests.

diving!

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

But diving is different.

Once you go down, you have to face all kinds of strange marine creatures. There was once a diving in Maudaivo. To be honest, this thing is really something that not everyone can accept.

People with claustrophobia and deep-sea phobia will really collapse when they get down.

Especially looking at fish in the sea.

It's not that fast, but due to the influence of the diving lens, it feels like it's magnified.

But before that.

Lu Hai planned to test it first, with the effect of shark repellent, and the effect of shark repellent. Lu Hai took out a fresh fish and dripped the fish blood into the sea where sharks were infested.

Sure enough, it didn't take long.

This attracted several sharks, swimming around the fishing boats, and Lu Hai put down the shark-driving bracelet.

The shark responded immediately and then left the fishing boat. According to the young shop owner, the shark is an animal that is more sensitive to electromagnetics.

This bracelet uses this feature to drive away sharks, and overall it is OK.

Lu Hai tried again the shark repellent, which is a chemical substance, but it does not necessarily work for all sharks.

Lu Hai is more worried about bull sharks. This kind of shark is curious and has a high attack power. He is not allowed to eat enough and take a bite and get bleeding. Then it will be a big deal.

Lu Hai tried the past one by one.

Overall, it is OK. If the shark repellent bracelet and shark repellent are combined, the sharks in this sea area will be driven away.

After ensuring safety.

Lu Hai made his first attempt and selected the first Warrior, who was wearing the Lakers' No. 6 suit.

Let’s call him No. 6 for the time being.

Lu Hai put on a diving suit and sunglasses on No. 6. He was not so anxious to let him go into the water, but let him get familiar with the oxygen-absorbing environment first.

At the beginning, No. 6 sucked very quickly, and not long after, he had a severe respiratory reaction. Lu Hai quickly pulled out the mask on his face.

This kind of thing can only be done slowly.

It's completely in a hurry.

He could only let him adapt slowly. After trying for about half an hour, the No. 6 Primitive Man finally mastered the tricks of using the breathing valve, and then Lu Hai lowered the ladder.

Let the primitive man walk slowly down. A yellow plastic tube is connected to his back, which is an oxygen supply tube, inserted from the clothes behind, so that it will not easily 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 the No. 6 Primitive Man.

Just look at the behavior.

After just going down on the 6th, he was still quite scared and kept moving. He finally relaxed a little after sinking to the bottom, because Lu Hai tied a lot of iron for him.

So he couldn't float up, but he could walk freely in the sea.

Facing this strange world, the primitive man No. 6 was very curious and frightened. After going on for two minutes, he didn't dare to move around.

After about five minutes of trying, he dared to let go of the ladder. Then, his body began to slowly sink.

For the first time, Luhai was not in deep waters, but in five meters deep seas, judging from the images uploaded from the underwater camera.

The clarity of the seabed is still very high. At the moment when the Primitive Man No. 6 went down, all the sea fish around him scattered, but there are still many snails on the seabed, and there are also a large number of oysters and abalones.

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

In addition, Lu Hai accidentally discovered that there were one or two sea cucumbers near the primitive man's landing site.

Lu Haiti hopes to find a white jade sea cucumber at the beginning, and then the fourth ring mission is over.

Unfortunately, this kind of luck did not seem to have happened to him. On the contrary, what's worse is that there are not many sea cucumbers in this area.

Considering the rarity of white jade sea cucumber, Lu Hai is a little suspicious. Even if the search for this sea area is completed, will a white jade sea cucumber appear?

The 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 still good and there was no struggle.

Almost five minutes later.

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

Then start trying 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 more than 3,000 meters deep, but the most suitable sea cucumbers to live in is the range of 5 meters to 20 meters.

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

If the sea level is a standard atmospheric pressure, then when the diver reaches the bottom of the sea 10 meters, the pressure it is under is exactly two atmospheric pressures.

Although the diving suit has a certain effect, it is not as big as imagined. If there is an old wound on the body, it is very likely that it will tear again under this water pressure.

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