It turned out that in the past three days, for some reason, the temperature in the Bing Yu River suddenly dropped a lot! As we all know, the temperature inside the Bing Yu River is rare in the world, even the temperature in some polar places is not as good as it, the last time Gu Lin relied on the strength of the natal celestial body and the support of the star bones, and even the fire burned in his body and was almost frozen and fainted inside, especially the cold at the bottom of the Bing Yu River. But in such a place, in the past three days, the temperature has continued to plummet by nearly a few hundred degrees!

At first, it was a crackling sound in the door of the treasure vault that caught the attention of one of Xuankong's senior brothers. The three brothers had been staying in the treasure vault, because the special material of the treasure vault kept out the water of the icy river, so they didn't feel the cold, and if it weren't for this crisp crack, maybe they still don't know what happened.

Following the brittle crack, the three of them found that the door of the treasure vault actually had a crack the thickness of a finger, and there was no trace of a strong attack on it, so the three of them immediately knew that this door was frozen and cracked raw!

This underwater treasure vault has existed since the existence of the Demon Brake Cave, and has been safe and sound for hundreds of years, and the materials used to build the treasure trove at that time are almost the most cold-resistant things in the world that the ancestors of the Demon Cave have carefully selected, and the materials of this attribute have not disappointed the ancestors, even if they put it into the bottom of the ice river they found, there is no trace of frostbite, so they can rest assured that they used it to build such a magnificent underwater treasure house.

But at this time, there was a crack in the door of this treasure house!

There must be a demon when things are impermanent, the three senior brothers immediately felt that something was wrong, and immediately the two senior brothers worked to repair the cracked gate, and as for Xuankong, through another exit, he dodged out of the treasure house, and his body was in the water of the ice river.

As soon as he came into contact with the icy river, Xuankong first shivered, and then his limbs were quickly numbed by the terrifying low temperature around him!

This situation is simply incredible. Xuankong's strength had broken through to the level of the sixth order of body refining not long ago, and his body's endurance had already far surpassed that of his previous self. In the past, even if I didn't use energy to cover my body, I had never been almost frozen by the river!

The water of the Bingyou River is even colder than before!

When Xuankong went back to tell the news to the two senior brothers, the two of them were also extremely surprised, although several people stayed in the Bingyou River all year round, but the three of them didn't know much about the Bingyou River, especially the terrifying low temperature in Hanoi, let alone the three of them. For a long time, the high-level people of the Demon Brake Cave have regarded the cold temperature of the Ice River as an innate attribute of the Ice River, and they have not carried out any investigation, and even if they want to investigate, there are few people in the Demon Brake Cave who can withstand the terrifying water pressure and the biting cold and do an investigation inside.

So the sudden drop in temperature, the three powerhouses of the Demon Brake Cave didn't know the reason, but they also thought that maybe it was just a temporary change in nature, so the three of them didn't report it to Tiansha. Instead, he used his own energy to constantly repair the door, thinking that after a while, maybe the temperature would return to the past.

But what they didn't expect was that it wasn't so satisfying, and the three of them only slightly delayed the rupture of the treasure vault door. Gradually, the three of them felt powerless, and the speed at which the frozen cracks grew was vaguely faster than the speed at which the three of them repaired!

At this time, the three of them finally realized the seriousness of the matter. In case the treasure vault is washed into by the icy river, then the consequences are unimaginable, I am afraid that many treasures that have been passed down for hundreds of years in the Demon Cave will be drowned at the bottom of this river. And the temperature in this is so low, even a strong person like Xuankong is a little afraid, who can salvage so many things? So if the babies indulge in it, it almost means that they will never see the light of day! This is undoubtedly a huge blow to the Magic Brake Cave, which is in the stage of rapid rise.

And by the third day, not only the gates, but even the thick walls began to creak, and it seemed that they would not last long!

And at this point, Xuankong finally didn't hesitate at all, and let his two senior brothers resist it first, and he returned to the main hall to move the rescuers!

"Frozen River...... What the hell is going on......

Tiansha's eyes flashed with a fine light, he didn't hear much about the Ice River, he didn't hear much from the previous sect master, in the past, he also planned to explore the bottom of the Ice River, the temperature at the bottom of the Ice River was extremely low, and what caught his attention at that time was that the soil at the bottom of the river was very soft, like loose sand, and there was no feeling of freezing into lumps because of the cold. At that time, Tiansha wondered if there might be another shijie under this layer of soil, and this layer of soil may not be the bottom of the Bingyou River at all, but at that time, Tiansha had just inherited the position of the suzerain, and there was no time and mood to explore under this layer of soil, so this matter has been rotten in Tiansha's mind, until this time the temperature of the Bingyou River plummeted, which made Tiansha remember this matter again, and Tiansha faintly had an intuition, that is, the occurrence of this strange thing, maybe it really has something to do with the things under this layer of soft soil！

"Let's go, let's take a look. ”

Tiansha didn't hesitate at all, and after finishing speaking, he disappeared into the room, and Xuankong followed closely behind.

A few seconds after the two of them left, the shadow appeared in the darkness of the room without warning, and said,

"That's it, that kid is still killing the mountain......

The distance between the main hall and the Ice River is not a distance at all for Tiansha, and Tiansha has only changed his qi a few times along the way, and his body has flashed here.

As soon as he arrived, Tiansha found that the Ice River was different from the past, the river showed a faint blue, and there was no slightest wave on it, just like a huge piece of light blue ice. And Tiansha has not yet gone down into the water, just standing on the edge of the water, he immediately felt a cold breath straight into the pores of his body, and the cold air of Senbai was like gunsmoke, rolling up from the water.

And this vast forest, which is dozens of meters away from the Bingyou River, is like an ice carving, and every tree, every grass, and every flower has become a crystal ice cube, crystal clear, shining in the sunlight. Tiansha glanced at this scene with some beautiful scenes, but his heart was a little chilly, before he came, he didn't even think that the coldness of this ice river had reached such a point, and this was only the outermost, so how cold was the bottom of the river?

Strange to say, everything around is formed into ice sculptures, but this icy river, as if there is never a point of freezing, still gently ripples from time to time.

Phew――

Tiansha's figure flashed, without the slightest movement, and quietly entered the icy river, without even a trace of splash.

Tiansha's eyebrows are already a little solemn, although this level of temperature can't cause him some trouble, but it is difficult to guarantee that the temperature of this water will not continue to decrease, although he has stood at the peak of the continent, but the strength will eventually have a degree, and it is only a matter of time before this water lowers the temperature to the point that he can't bear it.

After a few flashes, Tiansha came to the treasure vault, and sure enough, the two senior brothers of Uncle Xuankong were constantly repairing the cracks on the treasure vault, and from the looks of the two, Tiansha saw their exhaustion, thinking that it had been repaired for more than three days in a row, and no one could stand it.

And the two of them also discovered the Tiansha for the first time, and nodded as a salute, at this time they couldn't be the slightest relaxed, because the two felt that the treasure trove was ...... It seems that I can't hold on anymore!(To be continued......)
