If a holy fire is the supreme heaven and earth, the best will come, and the sun, moon and the universe will be.

A majestic sound rippled between heaven and earth. As soon as the sixth-grade mysterious fire appeared, the fire lights flashed around it continued to surge like a prayer. The fire tide surged, reflecting Zhang Chong's face. The sixth-grade mysterious fire in front of him was also greedily absorbing the surrounding aura under the reflection of the fire. The surging fire aura filled every corner. These hell-like flames are now the best tonic for Zhang Chong.

Although the fire is fierce, under the pressure of the sixth-grade mysterious fire, there is no fire. He dares to approach Zhang Chong's body within one meter. People are noble and humble, and the same is true for flames. Even if the mysterious fire is only at the sixth-grade level, its noble appearance cannot be erased at all.

Zhang Chong wandered in this ocean of fire, and he could feel the fire flashing constantly, and the flames of Xuanhuo became more pure. Obviously, the environment here is very suitable for the cultivation of the sixth-grade Xuanhuo. Under the fire of Mingmie, Zhang Chong's fingers flew up and down lightly. Xuanhuo was like an elf, and wisps of breath poured in and out of Zhang Chong's body, closely connecting Xuanhuo and Zhang Chong's body.

The hot temperature around him felt like he wanted to burn people, but for Zhang Chong, it had no effect at all. His mental power was completely attached to the mysterious fire and was constantly moving.

In his mind, he also remembered Yue's previous words. The seventh-grade mysterious fire has nothing to do with cultivation, but it is a complementary effect. Your cultivation is still at the transformation level, but it has been cultivated with the sixth-grade mysterious fire. It is extremely rare for him to cultivate it. Even if it is Lan Xiping, his cultivation has reached the level of despair. However, the mysterious fire he cultivates is only seventh-grade and has not been able to reach another level. This is also a shocking thing for him.

At present, Xuanhuo greedily absorbed the essence of the flames in this place, showing an extremely dazzling change. Could it be that although he had not broken through the transformation level, he could upgrade the Xuanhuo to another level?

Even Zhang Chong himself never thought about this. However, at this moment, it happened in front of him. He could only hear a "puff" sound. From where the inner flame of the sixth-grade mysterious fire was, something seemed to break open, and the liquid condensed like fat jade quietly flowed towards the outer flame. Under the action of this liquid, the fire light kept changing its color, becoming transparent and crystal clear, like a diamond or a star-like color, shining brightly.

This change lasted for about two hours, and the speed of Xuanhuo's change was extremely surprising. It had no suspense to the seventh level, making Zhang Chong's body feel extremely comfortable.

Silently, without any signs, the fires around seemed to have been discussed and disappeared at the same time, leaving behind a more brilliant seventh-grade mysterious fire, burning slowly in that place. The surroundings were pitch black and a cold feeling. This feeling made Zhang Chong, who had just broken through the mysterious fire, feel a little uncomfortable.

What will happen next? Zhang Chong couldn't think of it at all, but this could not stop his powerful mental power from feeling a scent of danger.

A silver-white color broke through the silence.

The wind and frost are like a knife!!

In an instant, Zhang Chong felt like falling into an ice cellar. The cold numbed every inch of his skin on his body, as if he wanted to absorb all the energy in an instant. Even the seventh-grade Xuanhuo in Zhang Chong's hand could not dissipate any heat in an instant.

The silver-white color accompanied by the cold, overwhelmingly attacked the sky, the hot and cold world, but the change happened so quickly was completely unresponsive. Almost in a breath, this place turned into a silver-covered world, and the magnificent crystal-like scenery appeared in the blink of an eye.

Zhang Chong also became part of this scenery. He was sealed in the frost without any resistance, like a sculpture.

Such a powerful cold breath is no longer something that people can resist. Zhang Chong's skin has turned pale. It seems that he has lost a slight ability to resist. The seventh-grade Xuanhuo is slowly shrinking. However, if you look closely, you can notice that there is still a very thin channel between the Xuanhuo and Zhang Chong's body. Through this channel, Xuanhuo slowly returned to Zhang Chong's body and quietly protected his heart.

Zhang Chong's body felt a huge pressure that he had never felt before. This pressure came from every inch of his skin. In addition to the cold, it also had an almost suffocating oppression. Although he had the armor of stars and the seventh-grade Xuanhuo protection, facing this endless sense of oppression, he did not have the power to fight back.

In his right hand, he held the heart-eating rod tightly, trying to use the power of his mind to break through the ice around him. The power of his mind was moving rapidly. As the undercurrent surged, a series of auras were about to spread. Although it was extremely small, it was still slowly growing.

However, what surprised him was that the power of ice was much greater than he thought. The aura dissipated by only a few dozen centimeters and then stopped again. Then, it was not helpful to let Zhang Chong activate it over and over again, and there was no progress.

Just when Zhang Chong was upset, he found that the ice had another change, and white particles as soft as velvet bloomed. These seemingly weak forces came and went freely in the ice, and wiped away the breaths that Zhang Chong had emitted one by one like a scavenger.

The breath that had just dispersed after a long time of light disappeared without a trace under this change. How could this change not make Zhang Chong feel the urge to vomit blood?

It seemed that everything could only be started over again, but this change was not something that Zhang Chong had to worry about. Without any time for him to change his moves, those velvet-like forces had already begun to circumnate towards the Heart-Devouring Stick. Judging from its arrogant attack mode, it was obvious that he would not give up until he broke through the Heart-Devouring Stick.

Under the heavy pressure, the heart-eating rod made an extremely unpleasant "squeaking" sound, as if it was about to break in the next moment.

And when Zhang Chong was unable to resist, he only heard a light sound, and a huge crack appeared in the middle of the heart-eating rod in his hand.
