When Li Cheng asked this, Yang Chen was also unexpected. All along, Li Cheng gave Yang Chen the impression that he knew everything, and he didn't have the slightest secrecy in front of Li Cheng, and he was completely seen through by him. But this time, it was clear that Li Cheng was distracted.

The Yin and Yang Burning Sky Fire can simulate any kind of flame that is fused, or it can be said that it is not a simulation, it itself contains the characteristics of that kind of flame, and it can naturally give full play to that kind of flame.

Yang Chen has never wanted others to know his details, so there are also two kinds of natal sparks that are manifested externally. C-fire Xuanmu Fire and Ding Fire Earth's Heart Fire are all three-grade fires, and they are not very clever fires, but whether it is Xuanmu Fire or Earth's Heart Fire, they are all fires that are very suitable for alchemy and medicinal materials.

In this way, Yang Chen gave outsiders the impression that he was just a very pure alchemist. Unexpectedly, this deliberate effect was concealed even by Li Cheng.

It was rare that Li Cheng had a place where he didn't understand and couldn't see through Yang Chen, and Yang Chen was naturally happy for a long time, and only then did he release the Yin and Yang Burning Sky Fire that had already taken shape.

The two fire dragons flew up and down beside Yang Chen, the two purple and cyan fire dragons were like living creatures, except that because the grade was still low, they could not simulate all the details of the dragons, and from a distance, they would really think that they were two living fire dragons.

"This is?" Even Li Cheng couldn't help but widen his eyes, carefully observing Yang Chen's two natal fire dragons, and he was stunned and couldn't speak anymore.

But Li Cheng is Li Cheng, and he quickly saw some clues from it. Suddenly, his face changed greatly, and he pointed at Yang Chen's two fire dragons and asked with some uncertainty: "This, this can't be the Yin and Yang Burning Sky Fire, right?"

Li Cheng's words suddenly made Yang Chen awe-inspired, especially for the family or sect that taught Li Cheng. The legend of Yin Yang Burning Sky Fire, which only existed in the Heavenly Court, he was able to know that this was by no means an ordinary profound background.

Sometimes Yang Chen even wondered if Li Cheng was also a doppelganger of a person in the immortal realm. But he soon dismissed the idea. Impossible, the immortal realm consciousness is in the lower realm, and more than ninety-nine percent of the memory will be lost, where will it be like this.

"Big brother is really like a torch!" Yang Chen couldn't help but sigh, Li Cheng was really knowledgeable, where could others call the name Yin Yang Burning Sky Fire.

"You're really a surprise to me. Li Cheng's incredulous gaze glared at Yang Chen again, and then turned to the two fire dragons. Observe carefully.

"The purple is mellow, and the cyan is pure. Not bad. It's a good foundation. After Li Cheng looked at it for a while, he finally gave a comment, and then asked: "Why are there only four grades, why don't you fuse high-grade fire, you still have a lot of high-grade fire!"

"I'm afraid that the foundation will not be good, so I haven't dared to venture in. Yang Chen also told the truth, for Li Cheng, a master who can easily control karmic fire. He also happened to ask for advice: "I want to fuse some low-level fires more, and then use high-grade fires." ”

"The foundation is on this. Actually, it's pretty much it. 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 the high-level fire, and if you have the low-level fire in the future, if you fuse it again, it will not affect the quality of the Yin and Yang Burning Sky Fire." ”

Yang Chen already had the heart to fuse the five-grade fire, but he didn't do it all the time, and now even Li Cheng said so, and he immediately made up his mind.

"It just so happens that the Red Lotus Karma Fire and the Peach Blossom Karma Fire are the most suitable fires for you in this Demon Continent, and they have unique features for dealing with demonic energy. Li Cheng persuaded here, and at the same time gave Yang Chen another surprise: "I have exactly two methods of manipulating karmic fire here, you can refer to them first." ”

With the words of good and evil thoughts that Li Cheng told Yang Chen before, coupled with the method of manipulating karmic fire given here, combined with the experience of Yang Chen's previous life, controlling karmic fire is no longer a problem at all. The only thing that needs to be considered, the estimation is time, this way over, maybe it has already reached the ground, and there is no way to successfully absorb the fusion.

However, this is not a problem for Li Cheng at all, the shadow ghost doesn't even dare to take a breath in front of Li Cheng, and he doesn't let Li Cheng say the east and the west. Li Cheng asked him to find a suitable place for the four girls to train, and it was not just a matter of saying a word.

As for the delayed time, it was even easier, and the Shadow Phantom only had to send a message back to inform the other companions that they had found all of them and were on the way. Now that the person has arrived, there is no need to worry about anything else. They are all masters of the Mahayana period, and it is normal to wait for a year and a half, and no one will be impatient.

In the following days, the four girls practiced under the guidance of Li Cheng, while Yang Chen began to absorb and fuse the red lotus karma fire and the peach blossom karma fire with concentration. The process is the same as that of low-grade fires, they are all absorbed by the Spirit Furnace at the beginning, and then used the Spirit Furnace as a buffer to fuse into the Yin and Yang Burning Sky Fire.

However, even if the process is the same, the difficulty is beyond the reach of low-level fire. The five-grade fire can already be regarded as the best that can be cultivated and utilized in the mortal world, and in his previous life, Yang Chen was just fused with a five-grade sun true fire, so he was able to survive the tribulation and ascend, and later achieved the Great Luo Golden Immortal. The power of the five-grade fire can be seen.

In his previous life, when Yang Chen absorbed the true fire of the sun, it could be said that he was nine deaths, and at that time, in order to take revenge, Yang Chen had to take this huge risk, and he succeeded by luck.

Although the difficulty of fusing the five-grade fire in this life will never be as high as in the previous life, this is not the sun true fire that Yang Chen is familiar with after all, but the red lotus karma fire and the peach blossom karma fire that he just received, and even Yang Chen has to cheer up the spirit of 120,000 points.

Absorbing the two kinds of fire into the Yunling Furnace was a relatively simple process, after all, as long as Yang Chen's Dao heart was strong, he would not be affected. No matter how you say it, the spirit furnace is still a dead thing, there will be no good or evil thoughts, and no matter how powerful the karmic fire is, it is impossible to burn a dead thing without thoughts.

But the next thing is not so simple, the fusion of the five kinds of fire, especially these two kinds of karmic fire, the slightest carelessness is the consequence of being counterattacked. Before starting, Yang Chen even had to use the Yunling Furnace to control the two karmic fires first, refining some messy elixirs, and while being familiar with the various medicinal properties, he was familiar with the fire properties of the two karmic fires.

It wasn't until Yang Chen thought he was proficient in the control of the two fires that Yang Chen began the process of fusing them. (To be continued.)
