Chu Heng took out the special box containing the cold fire of the bone spirit, and as soon as he opened it, he could tell the extreme coldness to come to his face.

"Bone Spirit Cold Fire!"

Chu Heng looked at the faint blue flame burning in the box, and his eyes showed a strange look, although this flame was not particularly powerful, but his two masters were like thunder.

Medicine Venerable, Yao Chen, and Yan Emperor Xiao Yan!

The flame of the Bone Spirit Cold Fire is cold and freezes the soul of the bone marrow, as if all living things will freeze under such a flame, this is an extremely cold flame, it can instantly freeze a person's soul.

The two extreme forces of yin and yang fused perfectly on it, giving birth to a rare fire between heaven and earth.

"Boy, you swallow it. Ye Yuan's voice suddenly appeared, startling Chu Heng.

Looking at the flame flower in front of him that was blooming beautifully, Chu Heng swallowed his saliva, thinking that it was better not to try.

"This, not well, there is nothing to prepare, if you swallow it, you must not be frozen to death or burned. Chu Heng's face was full of rejection.

He didn't buy it for swallowing, just because of the name of "Bone Spirit Cold Fire", and money didn't matter at all.

Besides, he is not Xiao Yan, he doesn't have "Incineration", he doesn't have the elixir to prepare for swallowing a different fire, and he doesn't have Yao Lao to help him, so it's possible to accidentally play with fire and self-immolation.

"Boy, listen to me, it's right! Swallow it, it's definitely beneficial! The ability to obtain this flame is certain, and it is possible that it will be assimilated, and you will be able to obtain a different fire physique, and you can improve your cultivation by devouring the flame in the future. Ye Yuan said "bewitched" in his mind.

"Really, it's fake, it won't happen, right?" Chu Heng was a little moved, devouring the flames to improve his cultivation, which seemed to be even more powerful than "Incineration".

"Stinky boy, do you want to try? You actually dare to doubt what I said, in terms of cultivation, I, Ye Yuan, may not be as good as Lin Chen, but on the flame side, I also burned the heavens back then, you actually dare to question my words!" Ye Yuan's angry voice shook Chu Heng's head for a while.

Chu Heng smiled bitterly, these strong people are all stinky tempers.

Looking at the "Bone Spirit Cold Fire", Chu Heng swallowed his saliva, and finally decided to give it a try, since Ye Yuan said so, it should be no problem.

"Boom!"

Chu Heng directly grabbed the cold fire of the bone spirit with his hand, and the feeling of starting it was cold, cold to the bones.

In an instant, Chu Heng's hands were frozen, but they were also burned by the flames, and pieces of meat were roasted.

As soon as he gritted his teeth, Chu Heng directly stuffed the bone spirit cold fire into his mouth, and swallowed it into his stomach with a "grunt".

"Cold!"

When the cold fire of the bone spirit is swallowed into the stomach, the first feeling is cold, as if it can freeze the mind and soul.

"Hot!"

After a while, the cold feeling turned into heat again, the heat that could burn the blood and soul.

Bear!

The terrifying flames directly enveloped Chu Heng's whole body.

His clothes and hair were burned to the ground.

No, there was no ash, the fire burned directly to evaporate.

Snort!

The flesh began to fall piece by piece, turning to ashes.

Those white bones were exposed to the flames, and they were also burned by the flames.

"Ah!!h

"Grass! Ye Yuan, didn't you say it's okay! How could this be!"

A terrifying scream came out, which shook the entire manor.

Chu Heng screamed miserably, this feeling of being scorched by the flames simply hurt his soul!

"Stains, it's okay, patience is over. ”

"You are also ruthless, and it is the first time I have seen someone dare to devour the spiritual fire of heaven and earth so directly, it is powerful enough!"

Ye Yuan said awkwardly.

Chu Heng was stunned for a moment, and then he didn't understand why he was completely deceived by Ye Yuan!

"Day, Ye Yuan, you play with me!!"

Chu Heng is really crazy, he was so pitted by Ye Yuan, and now he doesn't need the honorific title of teacher, and he directly calls him by his name.

"Calm down, it's okay, there's "Gonzo", it's no problem at all, if there is a problem, I don't dare to give you advice, don't worry. Ye Yuan said.

Chu Heng didn't bother to pay attention to him, although he did feel that there was a strange force neutralizing the damage brought to him by the cold fire of the bone spirit, but the pain in it was really not something that people should suffer.

"Crackle"

Chu Heng, who was suffering from the cold fire of the bone spirit, made a crisp sound from his body, as if it was the sound of glass breaking, it was the bones being scorched, and Chu Heng's eyebrows were tightly wrinkled together.

Well, if you can still see your eyebrows.

If it weren't for his strong will and the help of Gonzo, he would have been completely frozen to pieces and burned to ashes by this cold and scorching flame, even so, Chu Heng still felt very painful.

However, in the pain, Chu Heng still felt that this flame was constantly tempering his body, and in the process of refining and polishing again and again, the body that had been washed and cut down the marrow three times had eliminated some impurities, and the body was slowly strengthened.

Previously, Chu Heng's body had become like a treasure body after three times of marrow washing, and his cultivation was twice as effective with half the effort, and his power was unlimited.

Now, he was directly calcined by the cold fire of the bone spirit, although it was not as powerful as Taishang Laojun's alchemy furnace, but it was also a very rare forging body.

The extreme polishing of this extremely cold fire made Chu Heng's body slowly make a qualitative leap.

"Ah!!" It's just that Chu Heng, who was in extreme pain, still inevitably let out bursts of terrifying screams.

Rumble!

When the aura in Chu Heng's body touched the cold fire of the bone spirit, it was like encountering an open flame and gasoline, and it burned wildly.

"Are you going to start?" Chu Heng's face showed a look of surprise.

He could feel that the power that belonged to "Gonzo" was guiding the "Nameless" exercises to operate slowly, devouring and refining the cold fire of the bone spirit little by little.

When the power of devouring and refining is fed back into one's body, the feeling is like sucking a duck slice, which makes people feel infinitely addicted.

"Boom"

The burning bone spirit cold fire outside Chu Heng's body was frantically sucked into Chu Heng's body, and the "Nameless" exercise in his body was running wildly, like a machine with full power, quickly devouring and refining the bone spirit cold fire to enhance his own strength.

Originally, Chu Heng's body had been burned to the ground, but now it was like regaining his life, recovering the bear little by little and re-breeding.

These flesh and blood, after absorbing and devouring the cold fire of the bone spirit, have slowly transformed, and it is not an exaggeration to say that they are treasures.

The originally somewhat black flesh color was also becoming more and more white, and Chu Heng's speed of absorbing the cold fire of the bone spirit was also constantly increasing.

At the end of the day, Chu Heng could feel that a vortex had formed inside his body, frantically sucking the flames into his body.

When refining and devouring reached the final moment, all the energy of the bone spirit cold fire was absorbed, and the whole world seemed to be silent for a few seconds.

Subsequently, the sudden outbreak of "boom" swept Chu Heng.

Chu Heng's entire body erupted with flames, and this flame also helped the few impurities in his body to be burned away.

"Drink!"

Chu Heng only felt the power in his body, as if it was a volcano about to erupt, and then, as soon as he stretched out his hand, a floating blue flower appeared in his palm.

Quiet, enchanting, but with a hint of killing.
