The two had eaten, and Tian Xu started alchemy. What he wanted to refine this time was the Xuanyu Creation Pill that could help Zhou Aiping recover completely.

The elixirs used in this Xuanyu Creation Pill are the Heavenly Xuanguo and the Nine-Petal Jade Lotus. These two are both heaven-level divine medicines, and they come from the same psychic grass, and there are no auxiliary medicines added, so the difficulty of refining can be imagined.

However, now that Tian Xu has condensed the Danhuo, with the assistance of the Danhuo, he can spend most of his energy on the control of the elixir, and he no longer has to spend a lot of energy and aura to squeeze the aura in the elixir. In addition, when condensing the pill, the Dan Huo can also help him subdue the restless aura in the divine medicine, and it is also very helpful for building the formation.

Tian Xu didn't directly try to refine the Xuanyu Creation Pill, he was not familiar with the Danhuo enough, so he still chose several fourth-grade pills and refined them in order from easy to difficult.

After more than a dozen furnaces of pills were refined, Tian Xu was already quite familiar with this Danhuo, and after getting acquainted with it, he also became more fond of using Danhuo. With the help of Danhuo, he was much easier when refining Dan, and the quality of the elixir he refined was much stronger than directly using the aura to urge the Dan furnace, which doubled his confidence.

According to the Dan Fang, Tian Xu took out a Tianxuan Fruit and nine nine-petal jade lotuses, and was about to put them into the Nine Xuan Furnace, when Zhou Aiping suddenly said, "What kind of elixir is this? ”

Tian Xu said: "This is the Tianxuan Fruit, this is the nine-petal jade lotus, both from the psychic grass, it is indeed very rare. As he spoke, he handed over the two elixirs to Zhou Aiping and asked her to take a closer look.

Zhou Aiping took it and felt it carefully, returned the two magic medicines to Tian Xu, and said: "I have heard of the name of this Heavenly Xuanguo, and I know that it is the fruit of the Psychic Grass, but I have not seen the real thing. The nine-petal jade lotus had never heard of it at all. The aura level in these two divine medicines is lively, especially this Heavenly Xuanguo, which gives me a feeling that it is difficult to grasp, you have to be careful when refining it for a while, I have a premonition that there will be trouble. ”

Tian Xu also felt this way, and said: "How do you know if you don't try it?" Let's try refining it first, if you can't control it, it's a big deal to fry the furnace, and then start from scratch." I still have a backup. ”

Seeing Tian Xu put the medicine into the Dan furnace, Zhou Aiping suddenly said: "You go outside the cave to refine, in case the furnace is fried, I am worried that Ziyan will not be able to bear it." ”

Tian Xu heard what she said reasonably, hurriedly put away the Dan furnace, and walked out of the cave. He found a quiet valley outside, set up the Dan furnace on a large flat stone, observed that there was no abnormality around, and began to refine this Xuanyu Creation Pill.

It turns out that Zhou Aiping has rich experience in alchemy and is really prescient. In the final condensing pill stage, the aura in the Xuanguo that day really refused to be obediently bound by the formation. The total amount of aura in the Xuanguo that day was extremely large, and his nature was very lively, and with the help of the nine-petal jade lotus, he broke through the shackles of Tian Xu's aura and burst out.

Tian Xu only had time to protect the inside of the Nine Xuan Furnace, and the eruption of aura suddenly rushed open the lid of the furnace, making a loud noise, and the furnace exploded. The lid of the Nine Xuan Furnace was blown out dozens of meters away by this blow, and the surrounding big trees were put down by this powerful spiritual energy, and the big stones under their feet were also blown apart. If this happens in a relatively closed cave, I don't know what the result will be.

Tian Xu cleaned up the scene, picked up the lid of the furnace, returned to the cave with the Dan furnace in despair, and said, "Aunt Zhou, fortunately you reminded me in time, otherwise it is really possible to hurt Ziyan." ”

Zhou Aiping comforted him and said, "It's okay if you're fine." It's just a pity that those two heaven-level divine medicines. ”

Tian Xu carefully recalled the whole process of alchemy just now, and didn't realize that he had done anything wrong, but the personality of that elixir was too strong, and in the end, his aura couldn't completely suppress it at all.

However, he didn't gain nothing, through this failed alchemy process, he had a deep understanding of the Heavenly Xuanguo and the Nine-Petal Jade Lotus, and basically figured out their medicinal properties.

There was a lot of aura in the Xuanguo that day, almost it was compressed into a liquid aura, its aura was extremely unstable, full of unpredictable variables, if this thing was used alone, Tian Xu himself would definitely not be able to grasp it. He believed that the vast majority of Condensing Pill Realm cultivators today would not be able to deal with it, not only would they not be able to use it, but they would most likely be injured by it. However, this thing has a great enlightening effect on breaking through the barriers of cultivation and comprehending the way of all things, and it is simply a weapon to break the barriers to advancement, and it can basically be invincible.

The nine-petal jade lotus is the opposite, it contains very little spiritual energy, but it has a strong regularity and can infect everything. This is simply the best form of healing, and almost all injuries are the result of the disruption of the normal functioning of the body's internal laws. As long as the powerful regularity in this nine-petal jade lotus is developed, all internal and external injuries will be quickly straightened out by it and resume normal operation, and the injuries will of course be healed.

This regularity is a kind of formation-like existence within it, which is almost completely self-enclosed. If it was used alone, there was almost no way for an ordinary Ning Dan Realm cultivator to break through its own regularity. If you can't break through, you can't affect it, and of course, you can't use it effectively. In this case, this nine-petaled jade lotus is like a mortal thing without the function of an elixir.

Speaking of which, the effects of these two magic drugs are almost opposite, and if the two sides neutralize it, it will definitely be the best medicine. But it is precisely because of the opposite medicinal properties that when these two magic drugs are refined together, the medicinal properties conflict with each other, and they scatter in two, and it is almost inevitable that an explosion will occur.

This Xuanyu Creation Pill almost perfectly solves this problem. It requires the use of Tianxuan Fruit and Nine-Petal Jade Lotus from the same psychic grass, and it is best to "meet" them picked at the same time, and the relationship between the two is like that of brothers, which alleviates the conflict between the two medicinal properties to the greatest extent. At the same time, the nine nine-petal jade lotus could form a magical "Nine Lotus Trapped Spirit Array" to further suppress the irritable energy in the Heavenly Xuan Fruit and prevent it from exploding.

Even so, Tian Xu still felt that it was difficult to control when he was in Chengdan. At this time, in retrospect, for the sake of safety, he only planned to refine five Xuanyu Creation Pills just like when he was refining the Heavenly Bee Requiem Pill. This distribution method was in conflict with the Nine Lotus Trapped Spirit Array, and it was an important reason for the final loss of control. At that time, if according to the characteristics of the Nine Lotus Trapped Spirit Array, the pill was divided into nine pills, it should be much better.

What's more, when he was condensing the pill, he imitated the experience of alchemy in the past, hoping to absorb the spiritual energy from the air according to the total amount of spiritual energy in the elixir, and compress it into this elixir together, which was also one of the reasons for the failure.
