Chu Chen was naturally extremely careful in this step. It can be said that he was not at all careless. He looked completely serious in his eyes, and a trace of splendor emerged deep in his eyes! And with the injection of this medicine liquid, waves of fluctuations were also emitted from the Yin-Yang Black Gold Furnace, as if he had a sense of the injected medicine liquid.

After Chu Chen saw this, he was naturally not surprised. After all, the Yin-Yang Black Gold Furnace has been silent for many years. At least judging from the situation I saw in the Wind and Thunder Valley before, I don’t know how much the ashes on the alchemy furnace have accumulated.

It can be said that if Chu Chen had not brought this Yin-Yang Black Gold Furnace out of the Wind and Thunder Valley, it would have obviously been possible that the Yin-Yang Black Gold Furnace would have continued to remain silent in the Wind and Thunder Valley.

Such a spiritual weapon naturally has its own spiritual existence. Now Chu Chen uses this Yin-Yang Black Gold Furnace to refine elixirs and injects these medicine liquids into it. Obviously, the Yin-Yang Black Gold Furnace itself can feel all this!

There was some sensory presence faintly, and naturally Chu Chen noticed this!

"Now that you are in my hands, I will naturally not bury you!" Chu Chen said lightly, as if he had made a promise to the Yin-Yang Black Gold Furnace.

As Chu Chen opened his mouth, the continuous tremors of the Yin-Yang Black Gold Furnace finally calmed down, and replaced it with the pattern that appeared on the alchemy furnace. It was a pair of Yin-Yang fish, which now appeared on the alchemy furnace, which obviously meant the extraordinary among them.

After seeing this and injecting the medicine into it, Chu Chen did not hesitate at all. He directly circulated the spiritual energy, and in an instant it covered the bottom of the Yin-Yang Black Gold Furnace. There was also a strong burning sensation in the air in the cave!

This is the purple yang elixir fire that Chu Chen himself possesses. It can be said that compared with the fire spirit veins at the foot of this cave, Chu Chen's purple elixir fire is even stronger and completely superior.

Of course, this fire spirit vein is not completely useless. This fire spirit vein also has a powerful amplification effect on Chu Chen's alchemy fire. Under such an effect, the situation caused is also visible!

At a speed that is almost visible to the naked eye, the medicinal liquids in the Yin-Yang Black Gold Alchemy Furnace have turned into gas, like fog. These fogs are the most essence of these medicinal liquids.

Now Chu Chen naturally hurriedly covered the Yin-Yang Black Gold Furnace. After all, if some of these mist leaked out, it would obviously have a great impact on the final product of the elixir.

The Purple Yang Dan Fire is used to continuously temper these fogs. Although this step seems simple and has no difficulty, it is actually extremely difficult. It can even be said that it is an accident, which means there is a risk of a furnace blowing.

Naturally, Chu Chen did not dare to relax at all about this, and even his eyes showed great seriousness!

"In about three days, this Infant Transformation Pill can be refined!" Chu Chen said in his heart, and he had almost predicted the world, and of course he looked much more nervous.

After all, this Infant Transformation Pill cannot fail at all. Chu Chen even entrusted Feng Yan to use the reason for refining elixirs in this cave, and to get peace here!

After all, if you were disturbed by others during the alchemy, it would be obvious that it would be troublesome. With Su Mubai's entanglement, although he had killed Song Yunshan, an elder of the Leihuo Sect sent by Su Mubai, Chu Chen was still worried. In Chu Chen's opinion, perhaps Su Mubai could not have been so simple.

Maybe there is a possibility of sending people to come later.

Of course, Chu Chen doesn't have to worry about this now, refining elixirs in this cave of the Fire Spirit Vein.

Not to mention, the elder surnamed Yin at the mountain gate alone, in Chu Chen's view, his cultivation level had reached the second step.

As a mountain-seeker here, he will naturally be blessed by him.

Obviously, others cannot enter and exit at will, so Chu Chen naturally doesn’t have to worry about Su Mubai’s actions.

After thinking of this, Chu Chen also placed more eyes and gaze on the Yin-Yang Black Gold Furnace in front of him and devoted himself to the alchemy.

At this moment, just as Chu Chen was immersed in the alchemy, in front of the mountain gate of the Fire Spirit Vein, the elder surnamed Yin also looked at the location of Chu Chen's cave, which obviously existed with a bit of deep meaning and curiosity.

After all, for this old man surnamed Yin, he obviously has never encountered an alchemist who has a elixir of elixir cultivation and can have his own elixir fire. This is really curious.

Even in the eyes of the old man surnamed Yin, I have never seen it much. Naturally, the old man surnamed Yin is becoming more and more curious about Chu Chen.

"Although you have your own elixir fire, your cultivation level is just a elixir. Perhaps your future achievements are limitless, but your current achievements in alchemy should not be considered top-notch!" The old man commented softly, saying that you also slowly closed your eyes and continued to protect here!

On the other hand, in the Leihuo Sect, a young man in white robe looked not very good-looking in a gorgeous pavilion!

"What's going on? Why did Song Yunshan not come back for so long after he had been there for almost a day and a night?!" The young man in white robe snorted coldly, and his words were obviously filled with a strong sense of blame.

And the identity of this young man is naturally not a human being. It is the other one of the two Taoist sons of the Leihuo Sect, Su Mubai, and of course the grandson of the great elder of the Leihuo Sect.

But now, Su Mubai's expression is not very good-looking!

It was just because the elder of the Leihuo Sect he sent out had not come back for a long time! Originally, in Su Mubai's view, Song Yunshan's cultivation level had not yet completely entered the second step of cultivation, but in terms of the strength of the spiritual energy and strength, it was almost the same as that of the second step cultivator.

Of course, in this case, killing someone should be a simple matter.
