When Li Cheng asked this, Yang Chen also felt surprised. For a long time, Li Cheng gave Yang Chen the impression of being omniscient. He didn’t have the slightest secret in front of Li Cheng and was completely seen through by him. But this time it was clear that Li Cheng had been deceived.

The Yin-Yang heaven burning fire could simulate any kind of fusion flame, or it could be said that it was not a simulation. It has the characteristics of that kind of flame itself, and it could naturally display that kind of flame to the fullest.

Yang Chen has never wanted others to know his own details, so there are also two kinds of life source fire that appear externally. Third Fire Black Wood Fire, Fourth Fire Geocentric Flame were both third grade fire seeds, not very extraordinary fire seeds, but both the Third Fire Black Wood Fire and Fourth Fire Geocentric Flame were very suitable for alchemy and treatment of medicinal materials.

This gave the outsiders the impression that Yang Chen was just a pure alchemist. Unexpectedly, this deliberate effect even fooled Li Cheng.

It was rare for Li Cheng to have a place where he did not understand Yang Chen. Yang Chen was naturally proud of it for a long time, and then he released the already formed Yin-Yang heaven burning fire.

Two fire dragons flew up and down beside Yang Chen. The two purple and cyan fire dragons were like living creatures. Except for their low grade, they couldn’t simulate all the details of the dragon. From a distance, they would really think they were two living fire dragons.

“This is?” Even Li Cheng couldn’t help but widened his eyes, carefully observing Yang Chen’s two life source fire dragons, startled and couldn’t speak anymore.

But Li Cheng was Li Cheng, and he quickly saw some clues from it. Suddenly his face changed drastically, and he pointed at Yang Chen’s two fire dragons and asked with some uncertainty “This, isn’t this the fire of Yin-Yang burning the heavens?”

These words of Li Cheng immediately earned Yang Chen’s respect, especially for the family or sect who taught Li Cheng. The legend of the Yin Yang heaven burning fire that only exists in the heavenly court, he could even know that this was by no means an ordinary profound foundation.

Sometimes Yang Chen would even wonder if Li Cheng was a consciousness descended from the immortal world, but soon he dispelled the idea. Impossible, the lower realm of the immortal consciousness clone would lose more than ninety-nine percent of the memory, how could it be like this.

“Big Brother is really like a torch!” Yang Chen couldn’t help sighing, Li Cheng was really knowledgeable, how could other people know the name of the Yin-Yang heaven burning fire.

“You really surprised me.” Li Cheng’s incredible gaze glared at Yang Chen again, and then turned to the two fire dragons which he bserved carefully.

“Purple is full-bodied and blue is pure, it’s not bad, it’s a good foundation.” After watching for a long time, Li Cheng finally gave a comment, and then asked “Why is it only in the fourth grade, why not incorporate high-grade fire seeds? You still have a lot of advanced fire seeds!”

“I was afraid that I wouldn’t be able to lay a solid foundation, so I never dared to advance it.” Yang Chen was also telling the truth, for Li Cheng, a master who could easily control karmic fire. He also happened to ask “I want to incorporate more low-level fire seeds, and then use high-level fire seeds.”

“The foundation is up to this point. In fact, it’s almost the same.” Li Cheng nodded first, agreeing with Yang Chen’s statement. Then, after carefully observing the two fire dragons, he came to this conclusion: “You can fuse high-level fire seeds, and if you have a low-level fire seed in the future, if you merge it, it will not affect the quality of the Yin-Yang heaven burning fire.”

Yang Chen had already had the intention to fuse fifth grade fire seeds, but he hadn’t done anything. Now even Li Cheng said so, so he immediately made up his mind.

“It just so happens that the red lotus karmic fire and the peach blossom karmic fire are the most suitable fires for you in this demon continent. They are unique in dealing with demonic qi. During this time on the road, I will help to protect you so you can integrate these two kinds of fire seeds.” Li Cheng persuaded him, and at the same time gave Yang Chen another surprise “I happen to have two methods of manipulation of Karmic fire, please refer to them first.”

With the thoughts of good and evil that Li Cheng told Yang Chen before, plus the method of manipulation of Karmic fire given here, combined with Yang Chen’s previous life experience, controlling karmic fire would no longer be a problem at all. The only thing that needs to be considered, was estimated to be time. If they rush on the road, they may have reached the ground, and there would be no way to successfully absorb and merge.

However, this was not a problem for Li Cheng at all. The Shadow Demon didn’t even dare to take a breath in front of Li Cheng. Li Cheng asked him to find a suitable place for the four girls to cultivate, it was just a matter of speaking.

As for the time delay, it was even easier. Ying Mei only sent a message back and informed his other companions that they have found all the people, and it will be over when they are on the way. Now that the person was already in hand, then there was no need to worry about other things. They were all masters of the dacheng stage, waiting for a year and a half was normal, no one will be impatient.

In the days that followed, the four women cultivated under Li Cheng’s guidance, while Yang Chen concentrated on absorbing and fusing the red lotus and peach blossom fire seeds. The process was the same as that of the low-grade fire seeds. They start to be absorbed by the profound spirit furnace, and then use the profound spirit furnace as a buffer to merge into the Yin-Yang heaven burning fire.

However, even if the process was the same, the difficulty was beyond the reach of low-level fire seeds. The fifth grade fire seeds could already be regarded as the best for cultivation in the mortal world. In the previous life, Yang Chen just merged with a fifth grade fire seed, and was able to fly through the tribulation and ascend, and later became the a great luo golden Immortal. The power of the fifth grade fire seed was evident.

In the previous life, when Yang Chen absorbed the true sun fire, it could be said that he was dead. At that time, Yang Chen had to take this huge risk in order to get revenge, and he was lucky to succeed.

Although the fifth grade fire seeds were integrated again in this life, the difficulty would never be as high as in the previous life, but this was not the true sun fire that Yang Chen was familiar with, but the red lotus karmic fire and peach blossom karmic fire he just received.

It was a relatively simple process to absorb the two kinds of fire seeds into the profound spirit furnace. After all, as long as Yang Chen’s dao heart was strong, he would not be affected. The profound spirit furnace was a dead thing no matter what, there would be no thoughts of good and evil, no matter how powerful the karmic fire was, it was impossible to burn a dead thing without thoughts.

But the next thing was not so simple, fusing the fifth grade fire seeds, especially these two karmic fire seeds, a little carelessness would result in the consequence of facing backlashes. Before starting, Yang Chen even had to use the profound spirit furnace to control the two karmic fire seeds to refine some messy medicinal pills, familiar with the properties of various medicines, and at the same time familiar with the fire properties of the two karmic fire seeds.

It wasn’t until Yang Chen had considered himself proficient in manipulating them, that Yang Chen began the process of fusion.
