When all the dust settled, he leisurely took out the bottle of the best pill that had just finished the Dan Tribulation. Shou Yuan Dan, the ninth rank of Dan, its main role is needless to say, it is to increase the longevity of the monk's elixir. This kind of elixir is difficult to find in the world, not to mention that it is the best pill, according to Xiaoling's estimation, it can increase the life span of the monk by at least 300 years, and the function of this elixir can be described as against the sky. You must know that the longevity of Qi cultivators is only 300 years old, the foundation monk is 700 years old, the Jiedan monk is 1,200, the Yuanying monk is 3,000, and the transformation of the gods is 5,000. This increase of 300 years of longevity is tantamount to an additional layer of protection for everyone from Qi cultivators to the power of transforming gods.

A total of 3 top-quality Shou Yuan Dan were leisurely baked this time. You Ran also felt strange, didn't my father-in-law say that because of the lack of spiritual energy in this small realm, he couldn't refine the best pill? Then why was he able to refine it? Xiao Ling guessed: "Sister, is this because the aura of the space is strong? Or is it because you added the spiritual spring liquid of the space when you were alchemizing?" Or is it because my sister improved the pill when she was alchemizing?"

It's right to think about it, Xiao Ling pointed out the difference from what his father-in-law's alchemy manual taught.

Later, after a series of comparisons, it was discovered that although the spatial aura and spiritual spring liquid could increase the rate of Cheng Dan, it was confirmed that they could not produce the best pill, and the reason for producing the best pill was because of the potion added by Youran himself.

It turned out that in the process of researching and learning Danfang, with the memory of her previous life and her natural sensitivity to medicinal materials, she made a potion similar to the chemical stabilizer used in Western medicine in her previous life. Although this medicine uses relatively cheap and common low-level herbs, once this medicine is added to the Danfang, not only the impurities in the medicinal materials are purified to the greatest extent, but also play a very perfect fusion effect on various medicinal materials. In other words, this potion triggers the potential medicinal power of all medicinal materials, and resolving the conflict between all medicinal materials is equivalent to magnifying the medicinal power by at least 10 times.

Now it seems that there is only an increase in the efficacy of the medicine, which has greatly increased the rate of Chengdan, so the best pill has also been baked. The best pill has never appeared in this world! And according to these tests, this medicine can be applied to any pill, which means that any pill can be refined into the best pill. It's a big pie from the sky!

Youran and Xiaoling decided to name this potion a fusion agent. The birth of the fusion agent later caused a sensation in the entire immortal cultivation world. Because of the invention of this medicine, you will be called the "medicine fairy" by later generations, which is a later story, so I will not mention it for the time being.
