The Yin-Yang Heaven Burning Fire Prototype was just formed, and it was still very fragile. At this time, whether it is used for fighting or used for alchemy refining, it was not a good idea. Only when the Yin-Yang Heaven Burning Fire had grown to a certain level could these tasks be completed with it.

The only way to let the Yin-Yang Heaven Burning Fire to grow was to devour other fire seeds. Of course, if the low-level Yin-Yang Heaven Burning Fire wanted to devour high-grade fire seeds, such as the True Sun Fire and Moon True Fire and so on, there would be only one result, it would be refined by these advanced fire seeds. Therefore,the devouring could only start from the low-grade fire seeds, and slowly grow itself.

First Grade Fire Seed was indeed the best tonic for the Yin-Yang Heaven Burning Fire. After absorbing the remaining one, the Yin-Yang Heaven Burning Fire on the body of Yang Chen had begun to become stronger.

In the body of Yang Chen, there were dozens of Yin-Yang Flames in which Second Grade Fire Seed and Third Grade Fire Seed were combined. All of them were based on the Yin-Yang Heaven Burning Fire, which also made Yang Chen’s Yin-Yang Heaven Burning Fire more powerful than ordinary formed Fire Seeds.

After consuming all the first grade fire seeds, and then absorbing the second grade fire seeds, there were naturally not many obstacles. Now Yang Chen had not been too deliberate to control the absorption, all of them were done by the Yin-Yang Heaven Burning Fire spontaneously in the completion of the whole process, compared to the need for Yang Chen to completely control it, simple was not a little bit two points.

At least Yang Chen does not need to control the flames any more, for fear that the fusion of the flames will lead to an explosion. All this, the Yin-Yang Heaven Burning Fire had no such worry at all. The characteristics of this kind of flame, besides burning the sky, was engulfing. Devouring all kinds of flames, as long as it was within the scope of its grade.

Perhaps the primary Yin-Yang Heaven Burning Fire composed entirely of first grade flames could only absorb the flame of the first grade automatically. However, as long as two or more flames of the Second Grade flame were absorbed, the Third Fire and Fourth Fire was complete, the primary Yin-Yang Heaven Burning Fire would automatically absorb the flame of the second grade . Of course, when Yang Chen was absorbing, he would pay attention to the balance between the yin and yang.

The current Yin-Yang Heaven Burning Fire contained several flames of the third grade , which was no longer primary. Therefore, the flame of the second grade was completely absorbed in the fusion. The only thing that needed Yang Chen’s control was that the flame inside the profound spirit furnace should be cut off at the right time, so that the fire seeds of the profound spirit furnace was completely absorbed.

The two fire dragons in Yang Chen’s body, under the mad absorption of Yang Chen, began a slow change. Each time a flame was absorbed, the color of the dragon changed by one point. The purple flame was getting thicker and thicker, while the blue flame was getting lighter and thinner.

Of course, this change was only a trend. The second grade flame was at best, so that the primary Yin-Yang Heaven Burning Fire was no longer so fragile. It was still far from the real change.

Yang Chen had dozens of second grade flames, but even if the Yin-Yang Heaven Burning Fire spontaneously absorbed, it still costs Yang Chen at least half a year. Even if everything could be saved, only time was always irreplaceable.

When the number of the second grade flames exceeded 8,860, the spiritual power of Yang Chen changed again. The fire attribute spirituality began to increase again.

However, this time, the Third and Fire Fourth Fire began to be completely balanced. First of all, the Third Fire spirit power reached the ninth layer of the foundation stage. Then, in the Yin-Yang Heaven Burning Fire, the fire seemed to once again embark on a step of change, and the two spirits power of the Third Fire and Fourth Fire began to rise again.

The two fire dragons of the Yin-Yang Heaven Burning Fire, compared to the original prototype, were vivid by many times, and was more and more like dragons, and even Yang Chen could barely distinguish which was the head or the the tail.

What made Yang Chen wonder was that he thought the Yin-Yang Heaven Burning Fire two fire dragons head was on the tail of each other. Now he found that this was not the case. The purple fire dragon and the blue fire dragon were connected end to end, and their heads touch each other. The other’s tail was entangled.

Under the crazy absorbing of the two fire dragons, the Third Fire spirit power and Fourth Fire spirit power, like boiling, flowed into Yang Chen’s meridians and climbed. It seemed that in just a short moment, Yang Chen’s two spirit power collectively pushed to the tenth layer of the foundation stage, which was already the peak of the foundation stage, and only one step was needed, and it could enter the Jiedan stage.

The other series of spiritual powers, under the influence of the fire attribute spirit power, also began to improve in a joint nature,from the seventh layer foundation stage, all had a collective promotion to the eighth layer of the foundation stage to stabilize the stop.

The changes in the Yin-Yang Heaven Burning Fire and the improvement of spiritual power would inevitably bring about changes in the sea of consciousness. It seemed as if the two fire dragons in Yang Chen’s body were in harmony with each other, and the two fire dragons in the sea of consciousness had become much clearer. The only difference between the ones in Yang Chen’s body was that the two fire dragons in the sea of consciousness were coiled on the pillars of a Penglai Divine Wood. The two fire dragons directly turned the Penglai Divine Wood into a fire column with two colors.

Unexpectedly, his spiritual awareness skyrocketed again, from the early Yuanying stage, it directly rushed to the apex of the mid Yuanying stage, and it stopped at this point, and did not take a step forward, otherwise, Yang Chen had to face again the dilemma when his spiritual awareness was splitting.

That was a narrow escape, Yang Chen also secretly wiped the cold sweat on his head. Fortunately, he stopped at this point. If he went a little further, it would have been troublesome. Now at this point, this pill was good. Next time, when Yang Chen was promoted to the Jiedan stage,maybe he could solve this big problem.

With a long breath, Yang Chen stopped the cultivation. This time, the Yin and Yang Five Phases Secret Art collectively upgraded by one level. Although it was only a short period of six months, Yang Chen had to stop again to consolidate his cultivation base.

This was a step that cannot be omitted if Yang Chen still wanted to have long-term development in the future. Originally, according to the ordinary cultivation method, Yang Chen could not have such a fast speed of improvement. However, this life’s Yang Chen super strong fire controlling ability, let him have such a nearly cheat like general promotion.

Usually even the same fire cultivators as Yang Chen, at most could absorb a fire seed, absorbing hundreds of fire seeds like Yang Chen was absolutely incomparable. It could be said that there was no one before, and there would be no one after. No one could be faster than Yang Chen’s cultivation.

Although Gao Yue and Gongsun Ling claimed to be in seclusion, but actually used a completely different approach. In addition to the closed-door cultivation in this spirit power overflowing place,when they wanted to consolidate their cultivation base, they would go out to fight monsters.

But for Yang Chen to fight these low-grade monsters fight, for Yang Chen, there was not much experience to be gained. Therefore, Yang Chen’s way of consolidating his cultivation base was back to the aspect that Yang Chen was good at.

This time, Yang Chen chose the refining process,he wanted to refine a large Yin Yang Five Phases flying sword for himself, First Wood Flying Sword.
