The energy in the barrel is constantly surging towards the body of Butiantu, which is a process of self-cultivation, strengthening the essence and blood body, and enhancing the vitality.

The physiological development period is the stage when the body increases the fastest in this life, as long as it is reasonably exercised, bones, muscles, internal organs, vitality, cultivation and so on can grow rapidly. Of course, Bu Tiantu knew that he had already passed the period of physiological development, and now what he had to do was to continuously strengthen his body, replenish the lost essence, and increase his potential.

Now, Butiantu has already become an adult, and the body bones have already been formed, and if you want to be ten centimeters higher, it is thousands of times more difficult, but the loss of physique can be made up, this is the most important thing in Butiantu now, and it is also the thing that Chen Lao is helping Butiantu.

Time flies, and before he knows it, he has stayed in Bitan Mountain for nearly a year, during this time, his physique has been fully improved, and his cultivation has also been greatly improved, and he has been promoted to the realm of the Eight Heavens of the Day After Tomorrow, and he is only one step away from being promoted to the Nine Heavens of the Day After Tomorrow.

Of course, this also cost a lot of money, during this period, Cheng Lao went out several times, and I don't know how many elixirs he looted, all of which were consumed on Butiantu's body.

These elixirs are piled up, and it is estimated that they can create several powerhouses at the peak of the innate peak, and now they are just letting Bu Tiantu be promoted to the Eightfold Heaven of the Day After Tomorrow, all of which are used to lay the foundation for Bu Tiantu and make up for the potential consumed.

In the Bihan Mountain, in addition to the water that has not changed for thousands of years, there are more strange-shaped stones, stout trees, messy grass and thorns, rotten dead leaves all over the ground, and nothing else, there is no trace of life at all.

In the Bihan Mountain, the whole person of Butiantu turned into a phantom, constantly shuttling between the stone forests and trees, turning into phantoms, and he had already cultivated the wind god leg to a high and profound realm.

On this day, the dark clouds in the sky gradually gathered, and soon scattered raindrops began to fall, and soon, the thunder god roared, and with a thunderclap, the rain suddenly became violent, pouring down like a torrential rain, and the sky and the earth were suddenly full of water.

In an instant, Butiantu was poured into a soup chicken, and his whole body was soaked.

"It doesn't matter!" Butiantu was in a good mood today, regardless of the downpour overhead.

"Bang!" "Bang!" above the sky, Butiantu suddenly went straight down, and fell straight on the edge of the cold pool, splashing a large string of splashes!

"This ice is freezing so fast!" Walking on the edge of Hantan Pond looked helplessly at the top of Hantan, only to see that the surface of Hantan had condensed into a thick layer of ice.

"This ice must be at least 30 centimeters thick. How old is it for a while?" The water in the cold pool is very special, the density is much higher than that of ordinary water, and it does not freeze at extremely low temperatures. And whenever it rains, when the rain comes into contact with the water of this cold pool, the rain will quickly freeze!

It had only been raining for a while, and the ice was already a foot and two inches thick.

Bu Tiantu knew that even if the rain kept falling, this ice would reach a maximum of two feet thick, maybe it was to the limit, anyway, Bu Tiantu didn't know the specific reason, he also asked Chen Lao, Chen Lao just smiled and shook his head, and did not talk to Bu Tiantu in detail!

Butiantu walked to the side, picked up a big stone from one side at random, and walked to the ice, even if he stepped on this ice, Butiantu could feel a cool air constantly hovering under his feet.

"Boom!" Standing on the ice, Bu Tiantu stomped his foot violently, and after a loud roar, the solid ice, which was one foot and two inches thick, suddenly became fragmented under Bu Tiantu's feet and flew out in all directions, exploding into debris.

"I don't believe it, this time it's not to the bottom. Butiantu held a big stone weighing more than 100 catties and rushed into Bihan Pond.

This year, Butiantu just a month ago, can adapt to the cold pool, the cold pool water, after that, Butiantu almost every few days will try to dive deep under the cold pool, on the one hand, it is to stimulate the body with the cold pool water, on the other hand, step Tiantu Ye County to figure out what the bottom of the cold pool looks like, why it is cold all year round.

Hantan Tanshui, that is enough to freeze ordinary people to death at a low temperature, and Butiantu can easily resist just by relying on his own body, this is his cultivation achievements in the past year, even if a person in the early stage of congenital entry into Hantan, he will definitely freeze to death, but Butiantu is like a nobody, as if the pond water is not cold at all.

"Wow!" "Wow!" "Wow!"

Butiantu held the boulder in 100 catties with one hand, and kept paddling down with the other hand, and the body continued to sink, causing the flow of the pool water and making a gurgling sound.

"Now the sky is bright, but because of the heavy rain outside, the sky has become a little dark, as the step continues to dive, the visibility in the water is getting lower and lower, and if you continue, you will have to use your vitality. Butiantu thought about it.

Falling! Keep falling!

Twenty zhang!

Forty zhang!

Sixty zhang ......

"I've been to the cold pool countless times, but I'm still not used to this kind of cold, it's not comfortable at all!" Bu Tiantu kept muttering, if it weren't for the special water of the cold pool, which was good for his body, Bu Tiantu wouldn't have been okay to sneak into the cold pool, purely looking for discomfort.

Butiantu carefully looked at the objects on the side walls around Hantan, and every time he dived, Butiantu would leave some marks on the stone wall of Hantan, which were all references, which could let Butiantu know how far he had dived.

Butiantu, who was still diving, found the triangular mark in front of him, which was the depth of the last time his body couldn't stand the cold and began to use the acquired vitality body.

"It seems that I have improved again this time!" Bu Tiantu felt a little excited in his heart, after all, until he dived to the present, he still used his body to resist the cold, and he did not use the acquired vitality to protect his body, which was much worse than last time.

The road to the sky is still falling, seventy zhang, seventy-five zhang.....

"No way!" When Butiantu dived to seventy zhang, his body finally reached the limit, and he could no longer withstand the severe cold of the cold pool, so he immediately mobilized the acquired vitality in his body to protect his body.

"It's eighteen zhang deeper than last time!" Bu Tiantu thought in his heart.

With the acquired vitality body, the severe cold that Butiantu endured was much smaller in an instant, and his body became much more comfortable, he could continue to dive, and this time he must reach the bottom of the cold pool.
