The day's lessons passed quickly, and the Summit Academy used a very free and open teaching, and of course, this group of swaggering pirates did not have the patience to worry about their faces. For these teachers, it is better to have the skills to compete with the students, so it is better to drink some wine and bubble girls.

Another one, the martial artists who can enter the peak academy are all older, 60% of them are over thirty years old, and they can only choose open teaching for these people.

Impermanence took a cultural class in the morning, learned about some drugs in the universe that can strengthen the body, had a simple meal in the college's large cafeteria at noon, and began to conduct deep-sea pressure training in the afternoon.

At this time, Impermanence felt the power of the Peak Academy, an ordinary lecturer in the beginner class was able to dive to a depth of 90 meters without the assistance of any diving equipment.

During his years as a mercenary, he spent some time with members of the Navy SEALs, and he also read some internal materials about amphibious operations. Impermanence knows that the ultimate diving depth of human beings without protective clothing is 96 meters, which is already a Guinness Shijie record that can only be achieved by the most physically qualified people.

In the average adult, let alone breathing problems, in the deep sea of about 80 meters, the water pressure will damage his internal organs, and massive chest bleeding is almost inevitable. And the higher the water pressure, the nitrogen in the lungs will dissolve in the blood, and when the person floats up, these nitrogen gases released again will be a deadly poison.

Today, impermanence and impermanence must rely on their liliang to challenge the limit of 90 meters to a depth of 90 meters, without protective clothing and accident insurance, and even the sharks in this sea area are staring at these fresh meats.

The instructor seemed to be very familiar with this kind of training, and with heavy lead bracers on his wrists and ankles, he walked back and forth on the edge of the cliff, looking at the more than fifty rookies in front of him.

"The shijie record for ordinary people diving without protection is 96 meters, and even sunlight is a luxury at that depth, and the danger in the deep sea is not only those highly poisonous mollusc jellyfish, but also sharks swimming back and forth. Of course, none of this is a big deal, and your greatest danger is the sea around you......"

"At that depth, you will feel every bone creak as if it is about to break at any moment, and at that depth, the cold waters will make you feel like you are in absolute zero space...... Maybe you subconsciously want to wear a little more clothes to keep warm, but I tell you, every extra fiber in your body increases your resistance in the water, and this extra resistance can be the culprit of your death......"

"Now, just like me, take off all the clothes you can take off...... "After saying that, the big black lecturer took off his swimming trunks first, and paced back and forth on the edge of the cliff with the big bird.

Impermanence was extremely surprised to see, and he was dizzy when the big bird swayed, and when he looked back, "I lean on the ......" was actually stripped naked by both men and women, especially Lu Li's kid, where he stood like a mountain of meat.

Now Impermanence is completely convinced, the pirates who have fallen into the stars are really strong, and even the women here are so crazy.

"Now, everybody put on their lead bracers and jump down with me...... Remember, use your warrior's liliang to resist the pressure of the ocean......" After saying that, the lecturer jumped straight from the top of the cliff like a torpedo.

The scene behind is so magnificent, more than 50 naked men and women, black and white, tall and short, fat and thin, jumped off the cliff like dumplings, and the whole sea was full of white splashes.

"Ah...... Cool...... "Lu Li, the mountain of meat, almost hit the water raw, and the splashing Lang flowers were more than three meters high, and they all slapped on the head of Impermanence behind.

Almost instantly, Shijie around Impermanence immediately quieted down, and he pierced into the sea like a light water bird, and the splash was too beautiful.

As soon as Impermanence entered the water, he felt that the lead on his hands and feet was desperately dragging himself down, and the surrounding sea water was desperately trying to squeeze into Impermanence's body, and the pressure was getting bigger and bigger. But at this time, the impermanence did not have time to feel the pressure of the water, and now that they were surrounded by the sharks, the battle had begun.

Sharks with white bellies and sharp teeth are crazy to attack these fresh meat from the sky, but animals are always animals, how do they know how powerful these humans are, and if they dare to enter the territory of sharks, they will definitely not be afraid of these slippery beasts attacking.

The instructor took the lead, kicked over a rushing great white shark, and then cut off the shark's fin with his left hand like a knife. It wasn't until this time that Impermanence discovered that there was a circle of stainless steel wire on the instructor's wrist, and the cut shark fin was directly strung on it.

"Ah, it turns out that the people of Treasure Island also love shark fin?" Before Impermanence could think about it, suddenly the water behind him fluctuated strangely, and Impermanence's waist suddenly exerted force, and the whole moved two meters to the left, just to dodge the shark that sneaked over.

Immediately after that, Impermanence shot like lightning, and the knife in his right hand stabbed the shark's abdomen, and he actually relied on the shark's own impact to disembowelment the great white shark alive, and the red blood was rolling Xiangshang.

The instructor not far away gave him a thumbs up to Impermanence, and pointed to the shark fin in his hand. Impermanence knew that he was begging for shark fin to eat. Impermanence nodded, and as soon as the knife slashed a large piece of shark fin, it was in hand. It wasn't until Impermanence delivered the shark fins to the instructor that they discovered that the group had sunk to more than 30 meters of water.

As soon as the depth of the water exceeds 30 meters, the light begins to become dreamy. At this time, the sea level is like a multi-edged jewel. Schools of fish in the distance swam like black clouds on the outskirts of the crowd, and the battle overhead continued, with more than 30 shark carcasses already staining the ocean overhead a pale red. From a distance, there is a hint of the texture of an ink painting.

Just when Impermanence was deeply immersed in the beautiful scenery and couldn't extricate himself, suddenly a string of small bubbles gushed out from the corner of his mouth, and then Impermanence realized that the most dangerous enemy had appeared, and the powerful water pressure had begun to squeeze the space in his lungs.

Calm, now you must be calm, Impermanence remembered what the instructor said on the cliff, and began to use the liliang of his own martial artist to resist the strong pressure around him. Every muscle is trembling, every tendon is exerting, the ancient martial dragon and tiger are swimming in the impermanence's body, and the impermanence feels the pressure in the lungs greatly relieved in an instant.

At this time, the battle between the cadets and the shark was over, and everyone tried to make their range of movement as small as possible, and people had to find ways to save not only physical strength, but also ways to save oxygen in their lungs. However, in the battle just now, some of the students could no longer hold on now due to excessive physical exertion.

In the eyes of impermanence, four students untied the lead block and began to swim to the surface of the sea, estimating that the oxygen in their lungs had been exhausted by the battle just now.

As the depth of the dive increases, the more students give up, and the 30-60 meter interval is the one with the highest elimination rate, and around 60 meters, two-thirds of the students have already given up.

Impermanence is still persevering, and Lu Li and Merlin are not left behind, and the three of them get together and start challenging the deep sea 60 meters away.

How deep is 90 meters? According to the calculation of ordinary residential buildings, the height of a one-story building is about three meters, and the height of a building is 30 meters. So much seawater is pressed on people's bodies, and if they are slightly short of calcium, it is estimated that they will break their bones and tendons.

60m, 65m, 70m, 75m...... 85 meters, 90 meters...... Impermanence and the three of them finally broke through the 90-meter mark, and at this time, there were only four or five students left around the three of them. The instructor gave a thumbs up to all the students who had checked out Zuihou, and just as he was about to return with everyone, Impermanence suddenly noticed a huge shadow on the bottom of the sea.

Impermanence frowned as much as he could, his body slowly descending, and when he descended to a depth of 95 meters, he finally saw the bottom of the sea beneath his feet through the faint sunlight.

It's a silent deep-sea area, where countless shipwrecks are half-buried in the sand, and the high-pressure waters seem to be a safe that freezes time, so that those wooden sailing ships still retain the appearance of thousands of years ago.

At this time, the instructor had already discovered the impermanence of not obeying the command, and he waved his hand to let the impermanence come back, but the impermanence had now gone deep into the seabed at a depth of 105 meters, and that depth was the deep sea that the instructor could not dive.

Not only the instructor was anxious, but even Lu Li and Merlin were also anxious, but now they have reached the limit of their bodies, and if they continue to hold on, there will definitely be an accident, but they can't give up impermanence. Zuihou or the instructor rushed over and forcibly untied the lead from both of them.

When the lead fell to the bottom of the sea, the three of them suddenly felt a sense of relief, and the whole person began to rush towards it quickly.

Impermanence didn't see everyone leave at all, he was now slowly swimming to the side of the largest wooden sailing ship, and he clearly saw that in the bow of this quaint sailing ship, there was a yellow metal block with some patterns on it.

Brushing away the impurities and seaweed from the metal block with his hands, the brass badge appeared, which was actually the symbol of the noble alliance, and the wall guarded the hidden city behind it, and on the wall stood two ancient hoplite knights.

Impermanence removed the brass badge with both hands, and when he was about to enter the cabin to take a look, he suddenly felt his brain faint for a while, and the feeling of suffocation became stronger and stronger.

I really can't stay here for long, and Impermanence knows that although his body can still hold on, the oxygen in his lungs is almost exhausted, and if he doesn't leave, it will be really dangerous. He quickly untied the lead on his body, and the whole person rushed towards the sea level like a dolphin.

At this time, on the sea, all the students had already shown their heads, and everyone knew that Impermanence was challenging the limit mark 100 meters away, and they looked at Lu Li and Merlin with admiration on their faces.

"No, I'm going to save the adult, he loves it too much...... Who has an oxygen tank, who has protective equipment......" Lu Li was noisy and wanted to dive again. Just then, Merlin suddenly grabbed his hand and shouted.

"Look, there's a dark shadow underwater...... Could it be Lord Impermanence......" Before he finished speaking, a figure shot up from the bottom of the sea like an arrow. After Bai Lang rolled, impermanence suddenly came out of the water.

WhewW...... Impermanence opened his mouth and breathed in fresh oxygen desperately, surrounded by admiring gazes. I don't know who started first, and a round of applause rang out.
