"Fang Yi, remember, you must not float too fast..." Standing in front of the light curtain of the cave, Long Wanda specially reminded Fang Yi.

Long Wanda once read a scientific argument that specifically talks about deep diving. That argument shows that under deep water and high pressure, the human body will absorb excessive oxygen and nitrogen. During the floating process, these nitrogen will be excreted from the body.

If the rise is too fast, the surrounding pressure will drop rapidly, which will cause the nitrogen in the blood and tissue to form bubbles. These bubbles will burst due to the excessive pressure inside the human body, causing rashes, joint pain and even death. Long Wanda asked himself and Peng Bin to carry something out to control their rise speed.

"Old Long, I understand!" Fang Yi nodded seriously. He would not show off in such matters. Sometimes experience can save a life.

"Brother, Lao Long and I will go out first, you can follow behind!" Peng Bin stood in front of the light curtain, stretched out his hand and tried it. His palm passed through the light curtain without any hindrance and appeared in the sea water outside the light curtain.

"I feel a little uncomfortable, but it should be fine..." Peng Bin nodded to the two of them and said, "I'll go out first!"

Peng Bin is the kind of person who never delays his work. As soon as the words fell, his body passed through the light curtain. Fang Yi in the cave saw it clearly. As soon as Peng Bin's body went out, it seemed that it was pushed several meters away by the water flow.

When Peng Bin turned around after leaving, his eyes were confused when he opened. Obviously, he could not see the situation inside the cave from outside, and this was the formation that played a role.

"Fang, I'm out too!" Long Wangda held a big jar and kicked hard under his feet, jumping out of the cave. Suddenly, Fang Yi was the only one left in the cave full of fishy smell.

"If you make any progress in the formation in the future, you may be able to come back and try to repair the teleportation array..."

Fang Yi looked back at the depths of the cave and an idea popped up in his mind. If he reached the innate realm, it is very likely that Fang Yi would have to pursue those blessed places in the cave or the world that ancient Qi Refiners went to.

Of course, it is too early to think about this now, because even if Fang Yi has reached his cultivation level, he does not have a teleportation array that can allow him to go to another world. All of this requires another opportunity.

Tighten the backpack of the little devil's body, Fang Yi plunged into the light curtain without feeling any resistance. Fang Yi appeared outside the light curtain. At the same time, he noticed that his body was lighter, and the buoyancy of the sea water had already appeared, and a turbulent current rushed Fang Yi's body several meters apart.

"The water temperature is a little cool, but Big Brother and Long Wanda should be able to withstand it!"

Being in the sea, Fang Yi suddenly felt a cold wrapping him around, but Fang Yi could already stop falling into the cold and heat. After closing the pores around his body, the coldness was completely driven out of his body.

Fang Yi knew that Peng Bin's cultivation was not much worse than himself. Although Long Wanda was not as good as the two of them, his cultivation level also improved by leaps and bounds after practicing the inheritance technique. As for ordinary people, Long Wanda's physique has already surpassed the strongest athlete in the world.

"Hmm? It's indeed a formation!"

Fang Yi controlled himself not to float up, turned around and looked back. At this time, behind him, there was already darkness, and there was no light at all. There was no sound or light. Fang Yi's body was extremely quiet.

He reached out and took out the glowing stick from his pocket. This thing was specially left to Fang Yi by Peng Bin. Suddenly, a ray of light flashed within a radius of dozens of meters centered on Fang Yi.

"This... this is a mountain under the sea!" With the light of the glowing rod, Fang Yi suddenly saw that in front of him, there was a big mountain. I don't know how deep the mountain is below, but it extends straight like the sea surface.

Unlike the mountain peaks on land, the mountain that appeared in Fang Yi's eyes had many holes all over the body, covered with plankton in the sea, and countless colorful fish were passing through it, but there was a darkness directly in front of Fang Yi. Fang Yi knew that there might be the location of the cave.

After carefully observing the surrounding scene, Fang Yi kept it firmly in his heart. Now he had no time to check the formation. In such deep water, Fang Yi could not hold his breath for a long time as before, and he also needed to surface as soon as possible.

"The Wuliang Heavenly Lord, and there are sharks here..."

When Fang Yi was about to float up, he suddenly saw a huge black shadow swim towards him. Although he was not afraid of this guy, Fang Yi had no intention of fighting with it in the water. When he loosened his fingers, the glow stick immediately floated upwards.

The fluorescent stick floated much faster. Fang Yi even saw Peng Bin and Long Wanda twenty or thirty meters above his head. They seemed to have also seen the Greenland shark. However, after eating more than a dozen pairs of shark fins, Peng Bin and Long Wanda naturally couldn't be afraid of this big guy.

Fortunately, the Greenland Shark did not attack Peng Bin and Long Wanda, but followed the glow stick upwards. There were countless fish chasing light following the Greenland Shark. For a moment, in front of Fang Yi and others, the originally quiet ocean suddenly became lively.

The shark was very fast, and he caught up with the glow stick at a distance of dozens of meters and swallowed it into his stomach. In an instant, the sea returned to darkness, and Fang Yi and others became dark again.

Although it controlled the speed of floating, the buoyancy of the sea water still pushed Fang Yi and others to slowly float up. Soon Fang Yi saw a light appearing above his head, and his eyes could also see the scene in the ocean around his body.

Fang Yi has lived in the beautiful Fangshan since he was a child and has long been immune to the natural landscape, but the beautiful scenery under the sea is completely different from that on the land. The magnificent and strange scene far exceeds Fang Yi's imagination.

The mountains extending upward from the seabed still exist, but at this time the rocks were covered with coral reefs of various colors, and various shells and group animals were constantly passing through the coral reefs, making the mountain look vibrant.

Floating up further, the light in the sea became brighter and brighter. The sunlight projected in the quiet sea, like the light analyzed through the spectrum, and it seemed so beautiful. Even the mountains, rocks, shells and corals were dyed with colorful light, making Fang Yi dazzled.

Unconsciously, Fang Yi's floating body had already caught up with Peng Bin and Long Wanda. Seeing the worried eyes of the two, Fang Yi waved his hand with a smile. He didn't feel any discomfort. This deep water pressure could not have any impact on him.

The depth of the sea water they are now is almost a few dozen meters. Peng Bin and Long Wanda both threw away the jar they were holding and paddling with their hands and feet to control the speed of floating. After a while, the three of them arrived near the water surface.

"Wuliang Tianzun, is this...is ice on it?" After coming to the place close to the water, Fang Yi discovered that above their heads was a thick layer of ice. This layer of ice was like a mirror, refracting the sunlight above into the water.

With a "bang", Peng Bin punched the ice layer, and ripples appeared in the water he brought with him. However, because he could not borrow any force in the water, Peng Bin's body sank several meters, but the ice layer above his head was intact.

Long Wanda's breath-holding skills are far less than that of Peng Bin and Fang Yi. He is already feeling a little panicked. Seeing this situation, Long Wanda couldn't help but feel a little anxious because he knew that some thick ice layers in the Arctic often have an area of ​​dozens of kilometers, and they can't swim that far underwater.

What's even more terrible is that the coldness, which is like ice, is constantly eroding Long Wanda's body. If it weren't for the exercises that kept expelling this chill, Long Wanda would have been frozen to the point of being stiff.

As he approached Long Wanda's body, Fang Yi put a palm on his vest. After a trace of true energy was teleported in, he immediately straightened out Long Wanda's somewhat disordered aura.

He turned around and smiled gratefully at Fang Yi. Long Wanda pointed at it with his finger. If the ice layer cannot be broken, they are still in danger. Even Fang Yi cannot hold his breath under the water all the time.

Seeing Peng Bin rushing up again and preparing to continue to compete with the ice layer with his fists, Fang Yi pulled him and signaled that Peng Bin to let him go to the side. The broken sword appeared in Fang Yi's hand. When the true energy in his body poured into the broken sword, a sword light about one meter long flashed out.

After the sword light touched the ice above the head, the hard ice layer was like tofu dumplings. As Fang Yi shook, it fell into the sea water. In just a moment, a kind of sunlight different from the refraction of the ice layer appeared in the vision of Peng Bin and Long Wanda.

At this moment, Fang Yi kicked his feet suddenly, and his body seemed to be filled with a spring, and rushed out of the ice hole that was cut by him. When he saw the white earth outside and smelled the familiar air at the tip of his nose, Fang Yi couldn't help but let out a long roar.

This long roar continued, and all the turbid air that Fang Yi held in his chest was vomited out. It lasted for three or four minutes before he stopped. Looking back, Fang Yi found that Peng Bin and Long Wanda were both sitting on the ice, and his face was faintly filled with pain.

"Old Long, brother, what's wrong with you?" Fang Yi asked for some unknown reason. Logically speaking, they finally escaped from the sky at this time. They should be as excited as they are.

After hearing Fang Yi's words, Peng Bin used his hand to clean his ears and said with a laugh and cry: "I said brother, don't howl in that ghost and wolf, my eardrums were almost blown by your voice!"

"So too, I'm confused now and my head is a little dizzy!" Long Wangda took several minutes to speak. If Fang Yi's voice sounded a little longer just now, he would not guarantee whether he would be shocked.

"I'm sorry, I'm so happy!"

Hearing the two of them, Fang Yi suddenly understood. The long roar he had just now contained a trace of true energy, which was already a sonic attack on the people around him. If Peng Bin and Long Wanda were ordinary people, they might be really hurt by him.

"You guys talk first. I have to use my skills to meditate. This place is so cold..."
