Although Cheng Feng knew that his physical body was already very hard, he knew that this was not enough, he also needed a more terrifying high temperature to temper.

So Cheng Feng continued to move forward, refining in one place for one or two days and then continuing to advance, and his cultivation had been circulating and continuing.

When he came to the fifth crater, He Qingfeng found that his aura shield was about to be unable to support it, but Cheng Feng was still cultivating with the power of the fire here.

This guy is really a freak, he has been shocked by Cheng Feng again and again, and his heart has become numb.

So Cheng Feng felt as if it was normal when Cheng Feng continued to move forward, but this time he didn't dare to continue to move forward, but began to retreat.

He found that his aura shield had reached its limit, and if he didn't withdraw, he might be injured, and he couldn't bear the temperature here, he wasn't a freak like Cheng Feng.

Seeing that He Qingfeng had left, a smile appeared on Cheng Feng's face, he knew that his goal had been achieved, and the next time was the time to go crazy.

Before, he just did it for He Qingfeng to see, and his madness was still to come!

After He Qingfeng left, Cheng Feng was really crazy, he didn't want to die when he cultivated, that kind of madness, he was afraid that He Qingfeng wouldn't be able to bear it.

The Heavenly Machine Refining Body was running wildly, Cheng Feng completely opened his heart and let the power of the fire here wash his body, this kind of pain was the real pain, it was just a performance before.

When the endless power of fire entered his body, his body suddenly turned like an iron plate, and it was burned red, and even Cheng Feng felt very terrifying in that kind of pain.

But having experienced, he only maintained his firm belief and did not let himself pass out, and his physical body let the power of fire continue to be tempered.

One day, two days, three days later, He Qingfeng, who was waiting outside, was still undecided, and his body trembled when he thought of Cheng Feng's crazy energy, which was not something that people could bear at all. 、

And after several days, Cheng Feng didn't come out, He Qingfeng began to worry a little, he was afraid that Cheng Feng was really crazy, and if he hung up inside, it would be troublesome.

He still has to find a way to break through the realm! And it's a pity that such a terrifying genius boy hangs up.

But let him go in and look for it, he couldn't do it, and he couldn't get in at all because of the temperature in there.

Now he knew that his strength was really not enough, although he was a very powerful master in the ancient martial arts world, but as soon as he looked at Cheng Feng, he felt that he was nothing, although Cheng Feng's strength was still below him.

If the other party finds this kind of place when the two are fighting, he can't get in at all, so what's the fight with others.

While He Qingfeng was anxiously waiting, Cheng Feng's cultivation was still continuing, and he advanced a little more, and he was already about to reach the seventh crater, and the more this volcano went inside, the higher the temperature.

Cheng Feng was even thinking that if the Heavenly Machine Tower could be used, he would like to go down to the core of the volcano to see what was inside.

But he knew that his current strength was not enough, and he couldn't go in at all, otherwise he might have no return.

Although his cultivation is crazy, he will not be sent to death, although he has died once, but who will be afraid of longevity.

Cheng Feng's body had turned into a red body of fire, but he enjoyed this pain very much, because he could feel that his strength was rising step by step.

And a lot of impurities were burned out by the flames in his body, which made his body even lighter, but there was one thing that made him very dissatisfied, that is, he had endured such powerful pain, but he still couldn't really break through the withered nephew of the physical body and reach the next stage of the physical body.

According to Cheng Feng's cognition, the physical body is divided into lower grade, middle grade, upper grade, best grade, and immortal grade, as for whether there is anything above, he doesn't know, but he feels that there should be more, but he knows that it is difficult to cultivate.

Thinking that his physical body is so low-level, it is so difficult to cultivate, so it will not be even more difficult to cultivate in the physical body later.

But this is not difficult for him, as long as he has the opportunity, he will do everything to refine the physical body, so he is not afraid of difficulties, he is afraid of no chance.

Looking at the terrifying high temperature in front of him, Cheng Feng was ruthless in his heart, and immediately rushed over, if he wanted to make his physical body reach a higher level, he could only let himself experience more powerful difficulties.

Cultivation is to go against the sky, as long as you get through it, it will be a sunny day. After so many days, his ability to resist fire has reached quite an astonishing level.

When he had not advanced far, a feeling of dizziness suddenly appeared in his mind, and Cheng Feng was shocked, this was a sign that he was about to be unbearable.

"I can't be unconscious, I still have a lot of things to do, the best body, break it for me!" The experienced Cheng Feng knows that now is the most housekeeper moment, so he must not be unconscious, as long as he is unconscious, he may never be able to wake up.

With Cheng Feng's loud shout, a feeling of dizziness disappeared instantly, and then a terrifying flame power continued to wash over his body, as if a piece of iron was burned in the fire, and then something kept beating.

Cheng Feng, who had always relied on faith, didn't know how much time had passed, and suddenly he felt a bang in his mind, and then the terrifying flushing sensation in his body suddenly disappeared.

A powerful force was transmitted from his body, and Cheng Feng, who had been enduring great pain, suddenly let out a loud shout, raised his fist and smashed it directly into the ground.

It was the most comfortable he'd ever felt in days, and he could feel his body full of power, power that he had never seen before.

When Cheng Feng slammed his fist on the ground, a deafening sound suddenly sounded on the originally scorched ground, followed by the sound of the sky falling and the earth cracking.

One after another sparks were scattered everywhere, and yes, Cheng Feng's punch directly cracked the ground.

But now that he had done it, according to his guess, he could now fight against the innate fifth- or sixth-level masters with just his physical strength.

If you add some other means, even He Qingfeng, a master at the peak of the innate peak, can't help him.

This is a strong self-confidence, Cheng Feng only felt at this moment that his cultivation finally had some effect, and those were too weak before.

He Qingfeng, who was waiting in the pavilion outside the volcano, suddenly heard a loud rumbling sound from the depths of the volcano, and he frowned and didn't know what was going on.

And just when he was at a loss, a figure shot out directly, and instantly came to He Qingfeng's body.
