At this moment, just when Ye Qing was puzzled, Chu Chen set his sights on the Yin-Yang Black Gold Furnace, and then his spiritual consciousness expanded and looked over. Not only the spiritual consciousness, but also the mental eye also spread out at this moment. Looking at the Yin-Yang Black Gold Furnace, it was obvious that he wanted to see the name in it.

However, after checking this, Chu Chen did not see any problems inside. At least Chu Chen did not notice that there was any problems in this refined medicine liquid.

After all, Chu Chen is also extremely skilled in refining medicinal liquids. Not only is he limited to proficiency, but it can even be said to be almost equivalent to Chu Chen's habit. Whenever he gets a herb, Chu Chen can refine the medicinal properties of the herb into medicinal liquid to the greatest extent!

In this way, it means that there is no problem in the initial step of refining the medicine liquid!

"Where is there any mistake?" Suddenly, Chu Chen fell into deep thought. Ye Qing in the Chaos Ten Thousand Spirits Tower also noticed Chu Chen who was in deep thought at this moment. Seeing that Ye Qing didn't ask Chu Chen anything, Ye Qing also understood that Chu Chen at this moment should be looking for the problem in refining the pill just now.

Generally speaking, this is true for some alchemists. Every time they fail to refine their alchemy, they will reflect on themselves for a long time.

The purpose of this is very simple, which is to be able to successfully refine the pill in the future. Now Chu Chen is like this, and his whole mind is immersed in the analysis. Obviously, Chu Chen also wants to find the core problem of this failure!

Since there is no problem with the refined medicine liquid, the problem may be because of the fusion of medicinal properties between these medicine liquids?

When Chu Chen thought of this, he couldn't help but shake his head slightly. Generally speaking, such problems will only occur when refining some new elixirs.

And in Chu Chen's opinion, the pill recipe given by Ye Qing can be said to be extremely perfect. There is no result of incompatibility of medicine! Since that is the case, then it may be that something went wrong when he fused these medicines?

After Chu Chen thought of this, he shook his head again. Chu Chen had special confidence in this. There would be no mistakes in such a step.

And now when I recalled, there was no problem when I just refined the pills!

"These three points are impossible, so is the only problem that exists?" After Chu Chen checked these problems one by one, he suddenly thought of the only possibility, that is, the problem of Danhuo!

"There is a problem with the Dan Fire." Chu Chen said lightly, with a bit of special affirmation in his words. Ye Qing from the Chaos Ten Thousand Spirits Tower was stunned after hearing this!

"Then, what is the problem with this Dan Fire?" Ye Qing was extremely puzzled immediately and asked Chu Chen, and even a little surprise emerged from the depths of his eyes.

After all, in Ye Qing's opinion, it should not be so easy to find the reason for failure.

Obviously Ye didn't expect that Chu Chen had found the problem of this failure in such a quick time!

"I have confidence in controlling the elixir fire, and there should be no mistakes. I have refined the Infant Transformation Pill here before!" Chu Chen said lightly. Less than a month ago, Chu Chen refined the Infant Transformation Pill during this Fire Spirit Vein and successfully entered the realm of the Nascent Soul.

Of course, after analyzing now, Chu Chen does not think there is any problem with his own elixir control, and what is wrong with the fire spirit veins here!

But now, the only possibility exists is that something is wrong with this Dan Fire!

"Wait a minute, I used the fire spirit vein here before to refine the Infant Transformation Pill. As for my own purple yang elixir, it was just used to assist me. But this time it was not the case. Instead, my own purple yang elixir fire was used as the main alchemy elixir fire, and this fire spirit vein was an auxiliary me!" Chu Chen murmured to himself, and while speaking, a trace of light appeared in his eyes!

This simple difference is also the difference between the two times of refining pills!

Chu Chen did not think that there would be any problems in the fire spirit veins here in such a month.

After all, such spiritual veins can generally last for a long time!

So now it seems that the only possibility is...

"Is it because of my own Ziyang Dan Fire? What's wrong with it?" In an instant, Chu Chen had such thoughts in his mind, even with an incredible feeling.

After all, the elixir fire that Chu Chen has had can be said to have owned for hundreds of years. When he was practicing in the Ziyang Sect on the other side of the starry sky, Chu Chen already owned the Ziyang elixir fire as the elixir fire for himself to refine elixirs!

No problem has happened in the past few hundred years!

Chu Chen could hardly believe what would be wrong with his own Ziyang Dan Fire!

However, in the current situation, the only mistake is probably the Ziyang Pill Fire!

Thinking of this, Chu Chen naturally had no hesitation and directly used his own purple yang pill fire. In an instant, the pill fire was completely presented to Chu Chen.

Chu Chen had never checked it because he was eager to refine the elixir needed by Ye Qing.

After all, this Ziyang Pill Fire has been owned for hundreds of years, and it is not even a simple item. It can almost be said to exist in Chu Chen's body and is part of Chu Chen's body. It is like eyes, nose, and ears, and it is integrated with Chu Chen. Every inch of Chu Chen's flesh and blood can evoke this Ziyang Pill Fire!

Because of this, I hardly imagine what happened to the Ziyang Pill Fire, so when Chu Chen refined the alchemy, he never checked the Ziyang Pill Fire.

However, now, after failing to refine this pill, Chu Chen had to check the situation of the Ziyang Pill Fire!

Ye Qing in the Chaos Ten Thousand Spirits Tower was naturally very curious at this moment. The purple sun pill fire that Chu Chen called out now came, and Ye Qing's gaze also showed some confusion.
