Bi Yu's long howl was really a blockbuster.

I don't know how many martial artists in the cold cave this day, I can't help but be shocked, just by sensing Bi Yu's qi from afar, I already understand his strength.

This kind of strength is not momentum, but the terrifying power contained in the long roar, without a trace of vitality infusion, but it can shake the entire Tianhan Cave with the power of a roar, and even make the entire floating mountain tremble slightly.

What a great power this must be!

The object of suspicion by countless people, at this moment, Bi Yu has disappeared in the cave passage that has been closed for two months.

On this day, the cold cave has nine twists and turns, deep and extended, and thousands of passages collude with each other to run through, like a snake road ant nest.

The strong wind in the cave gusted, setting off the cold air and breaking the ice layers, obviously there was no light source, but there was some invisible glimmer in the cave.

As a result, even though it is pitch black, you can see the outlines of some objects in general.

In fact, the strength has reached the level of Bi Yu, even if his eyes are closed, all the scenery around him can be completely sensed clearly with the help of qi.

Not to mention that if he enters the state of self-forgetfulness, the radius is a hundred zhang, and all things in heaven and earth are reflected in his heart, and nothing can escape his senses, not even some Qi King Realm powerhouses who have hidden their breath.

After two months of retreat, the cold air in the cave had been completely adapted by his body.

If two months ago, he might still feel the pain that pierced the bone marrow, but now, he only felt the cold air blowing around him, like a spring breeze.

This kind of gap in feeling is huge, which is a bit incredible, but in fact, as long as you think about it, Bi Yu has been in a state of complete ice for the past two months, which is even more terrifying than his body being exposed to the cold, and he can be relieved.

The body is frozen, and that kind of chill is enough to freeze to death any strong man in the Qi Madness Realm, even if it is a fierce man who once died in his hands, with the strong physique of the other party, if the ice is frozen in this cold cave for two months, it will definitely die.

There is an extremely obvious gap between the physical strength of the 300 giant elephants and the physical strength of the 400 giant elephants.

This gap is like comparing an iron sword with a hundred steel swords, there is a qualitative difference.

Compared with the physical strength of Bi Yu's five hundred elephants now, this gap is even more obvious.

During the two months of frozen retreat, his physical strength was strengthened by the stimulation of the doomsday battle body and the endless chill.

The initial feeling and pain of being frozen to death gradually weakened as time went on, as the strength of his physical body continued to increase, and in the end, it disappeared completely.

Maybe even Bai Aya'er never thought that in just two months, Bi Yu could fully adapt to the cold air in the cold cave with just his physical body.

This is extremely incredible, most of the martial artists of the Qi King Realm can't do it, and it can only show that Bi Yu's current physical strength is too terrifying, don't say anything about water and fire, it should be said that ice and fire are invulnerable.

"With my current physical strength of five hundred elephants, it is too difficult to get promoted, at least the cold stimulus in the cold cave this day is completely immune

But there is still a month to leave this place, and this month's time cannot be wasted.

The floating mountain that built this Tianhan Cave is so large, presumably the area inside this cave should also be extremely vast and deep, so explore it well, and maybe there are some other discoveries. ”

In the process of moving forward, Bi Yu's eyes were sometimes blurred, and his heart changed, and he avoided some occasional martial artists with a keen sense of the surrounding environment in a state of selflessness, and his figure was like a ghost.

He had a strong curiosity about this cold cave, where did such a terrible cold in this cave overflow and spread, and whether there was a source where the cold would be even more intense and terrifying.

Once this idea was generated, it took root in his heart, and Bi Yu became more and more sure of this speculation.

Everything has its own reason for birth and existence, if it is said that the cold qi in this cold cave is completely created by the power of the formation, Bi Yu will not believe it at all.

There was no formation formed by a medium, and even if it was a formation, even if it was a nine-rank formation, it was impossible for it to gather such a rich and large-scale cold qi.

Even if it can be done, the consumption of that kind of formation energy, even if there is a formation internal circulation to restrain the power of heaven and earth to replenish itself, it is definitely a great loss, and it will produce a vision of heaven and earth, making a radius of a hundred miles empty, and not a single inch of grass will grow.

"If I can find that source, where the formation eye is, maybe my physical strength can be improved again. ”

Bi Yu has always been a man of action, almost thinking of something, after the plan is made, he will definitely take action and act resolutely.

Finding the source of the birth of the cold qi in the huge Tianhan Cave, and finding the location of the array eye arranged when the Tianhan Cave was constructed, this kind of crazy idea may only be thought of by a crazy person like Bi Yu.

Others still need to resist even the cold air escaping everywhere in the Tianhan Cave, not to mention walking like flying in this Tianhan Cave, searching for something everywhere.

Even if it is a strong person in the Qi King Realm, he will not be full and hold on to find some source of cold qi, at least these escaping cold qi is enough to meet everyone's grinding needs, no matter how strong it is, I am afraid that no one can afford it.

Moreover, the Tianhan Cave is too big, extending in all directions like a labyrinth, and finding the source of the cold in such an environment is tantamount to looking for a needle in a haystack.

After all, this source is equivalent to the eye of the array, which has been perfectly shielded, so that the degree of cold is the same as the change of cold in the surrounding environment, and there will not be much difference.

Even if Bi Yu's ability to sense the environment with his selfless state of mind is far beyond ordinary people, he is not completely sure to find the location of the array, which requires a lot of mental effort, and more depends on luck.

Just like a headless fly scurrying around, Bi Yu suddenly paused, the blurred color in his eyes, there was a moment of dazedness, he froze in place, as if he was thinking about something.

After a long time, he slowly remembered the figure that was gradually becoming clear in his mind.

"I can't remember it, but I still remember, it's her"

In his eyes, there was gradually a clear color, but soon, this trace of clarity dissipated, and turned into a blur again, and his figure spread, flying towards a certain prescription position.

There, there was a faint fire, swaying in the howling of the strong wind, which seemed to be extinguished at any moment, but it was always so tenacious.

The fire, though faint, was still so bright in this dim cavern.

A vague figure of a woman, curled up under the light, her breath was weak, her body did not have any temperature that a human body should have, and her body was full of fine ice crystals.

It looks like an ice corpse.
