The sky is cold and the wind is cold.

Ice crystals are everywhere in the cave, ice cubes are hanging upside down, and an almost milky white cold air fills the entire cave.

At a glance, people can see that it is white, and they can't see the upper and lower surroundings, and they can't see where the cave stretches out.

Although he was prepared when he came, when he actually entered the Tianhan Cave, Bi Yu was still shocked.

Tianhan Cave is not on any hill in the inner mountain, but in a floating mountain, extending in all directions to nearly tens of thousands of caves and cave entrances.

In fact, in the inner mountain of the Nebula Pavilion, there are not a few floating mountains like this.

Controlled by the power of the formation, suspended in the air above the reckless mountains of the inner mountain, it is the most special area of the Nebula Pavilion, and it is a special cultivation place for disciples to sharpen.

On weekdays, if you look up at the sky, a martial artist whose strength is not in the Qi King Realm will not be able to see the shadow of the existence of these floating mountains at all, and even if you take the flying boat into the sky, you will not be able to reach the location of these floating mountains.

It was a void completely distorted and covered by the power of the formation, between the illusory and the real, and it was the greatest essence of the Nebula Pavilion.

Bi Yu was also under the guidance of the same door, and only then did he find the teleportation hall that entered the Tianhan Cave, and in the eyes of many people full of malicious speculation, he teleported to one of the entrances of the thousands of caves in the Tianhan Cave.

As soon as Pu stepped here, a strong wind struck from inside the cave, and the terrifying impact made Bi Yu's body shake and almost be swept away.

This strong wind is even more cold to the bone marrow, colder than the coldest ice, blowing on the human body, like a sharp steel knife, with Bi Yu's strong physique, even at the moment when the wind came, the muscles collided with it and made a piercing sound like gold and iron.

"It's a cold cave. Bi Yu gasped, looked at the vast clouds and mist-rolling world outside the cave entrance, and couldn't see the ground below at all.

Of course, if the cold cave is designed like this, there will naturally not really be a strong wind that will blow people out and fall to their deaths.

The layer of misty light that shrouded the entrance of the cave was the guardian formation.

Even if a disciple teleported to the cave and didn't stand firm and was blown out of the cave at the first time, he would not directly fall out of the cave, but would be blocked by the formation, and would not have to worry about his life.

Standing firm, Bi Yu's eyes flashed, looking at the rock wall of the cave that was completely covered by solid ice, the cold air was blown by the strong wind like mist, and the biting chill seeped into the bone marrow, and after a while, his hair, including his clothes, was condensed into a wisp of thin ice.

It is not difficult to imagine how huge the consumption of vitality will be caused if you run the vitality to keep out the cold in this cold cave.

"In this environment, it is a great tempering of the Yuan Qi, and the cultivation of the Qi is the fundamental method recognized by almost all martial artists, which is undoubtedly no wonder that most of the disciples who enter the Tianhan Cave choose to use the Yuan Qi to ward off the cold.

One is to refine the purity of vitality, and the other is to alleviate the pain of the flesh and body.

It's just that there will be a time when the vitality will eventually be exhausted, even if you bring enough elixirs to replenish the vitality, in this environment, the recovery speed is not satisfactory, and you will still have to endure the pain of refining the body at that time. ”

While thinking, Bi Yu strode forward, against the strong cold wind, and headed towards the inside of the cave, the more he thought about it, the more he felt doubtful.

It stands to reason that most of the people who step into the martial arts, especially the disciples of the Nebula Pavilion, are not weak-willed, even if they have a temperament like Gao Ling, when they are forced to do so, they will burst out with tenacity far beyond ordinary people.

In this case, how can anyone not endure a little bit of grinding?

After all, this Tianhan Cave is indeed a good place to temper vitality and physique, if it is helpful to strength, presumably no martial artist will refuse, unless this place is really terrible to a certain extent, it will make people ignore the benefits and choose to resist.

But at the moment, Bi Yu didn't notice anything wrong with this place, except that the cold was really unbearable, but it was also within the scope of gritting his teeth and insisting, but it didn't get to the point of changing the color of that kind of talk.

"What is the reason?" Bi Yu frowned and pondered, and gradually came to the depths of the cave, and he could no longer see the details behind him, and the light at the entrance of the cave had disappeared.

When I arrived here, the cold was even stronger, and the mist became like a rolling tide, bathing the human body, making people move a little slowly.

At this point, Bi Yu felt some pressure, only to feel that his hands and feet were a little stiff and numb, the blood flow in his body had slowed down a little, and his face was a little blue.

I couldn't help but suddenly, "Yes, with my physique, even Bai Aya'er has said that the strength of the physical body is far above her, so the other disciples of the Nebula Pavilion, even if some have refined the physical exercises, it is estimated that there is a huge gap with the strength of my physical body."

At least, among the disciples of the Nebula Pavilion, there has not yet been an existence that has cultivated the strength of the flesh and body to the level of three hundred elephant powers.

In this case, for a while, even I feel the numbness of my limbs being frozen, so the others are afraid that they will be even more unbearable, and even the slightest carelessness may be frozen to death.

Although this is related to the fact that I did not use my vitality to keep out the cold, but after thinking about it for a long time, there will always be people who will run out of vitality, facing this situation, and the pain of life and death dilemma will be like a year, and it is no wonder that few people dare to set foot in this cold cave. ”

After thinking clearly about the key, Bi Yu was also awe-inspiring, and he had the most intuitive understanding of this Tianhan Cave.

This is an extremely terrifying blessed land for cultivation, so terrifying that most people dare not set foot in it even if they know the benefits of cultivating in it, and only a few geniuses among the geniuses, or those who are proud of the heavens, dare to regard this place as a place of cultivation on weekdays.

"Tianjiao, the reason why it is Tianjiao, it is far beyond ordinary people in all aspects, although this Tianhan Cave has a great effect on the refining of vitality, but it is Tianjiao, and whose vitality is not pure enough?

I'm afraid that they have reached the level of almost liquefaction, and if they want to be tempered again and improved, with Ling Han of the Heavenly Cold Cave, it is impossible to freeze people to death.

In this way, only the cold qi refining body is the most helpful to me, which is probably the reason why Bai Aya'er told me not to use vitality to keep out the cold. ”

Bi Yuqiang endured the pain of the cold bone marrow, suppressed the vitality in his body to protect the body, but operated the vitality according to the route of the doomsday battle body, and under the stimulation of the rich cold qi, he constantly tempered the flesh and body.

One week after another, the effect of refining the flesh and body of the doomsday battle body was exerted to the extreme under the stimulation of the cold air.

The figure of Bi Yu sitting cross-legged in the cave seemed to be a container for absorbing cold air, and all the cold air around him was rolling towards his body.

Gradually, with his body as the center, a storm of ice and snow was set off around him, drowning his entire body and freezing into humanoid ice crystals.
