The Honey Herb Immortal Lotus Pill was still ordinary, but this Heavenly Bee Requiem Pill and Xuanyu Creation Pill were very peculiar, and they didn't even use auxiliary medicines, only two main medicines from the same source to refine them. He carefully studied the formulas of these two pills and found that although the medicinal materials were simple, they were quite troublesome to refine. Just completely controlling the medicinal properties of this Heavenly Rank Divine Medicine was a huge problem.

You must know that when the elixir enters the ground level, it is possible to produce a hazy self-consciousness. Once you enter the Heavenly Level, you will inevitably have a spiritual consciousness, and this spiritual consciousness will always refuse to be swayed by the user with the powerful spiritual energy inside the divine medicine, and may even explode in anger when it is absorbed. Therefore, the pills refined using the Heavenly Rank Divine Medicine are often very complex, and most of the ingredients and operation steps in them are prepared to suppress the will of the Divine Medicine.

If suppressed in this way, the aura in the magic medicine will lose a lot, and the part that is retained will not have many immortal characteristics, it is a real tyrannical thing, a waste of good things.

The Heavenly Bee Requiem Pill and the Xuanyu Creation Pill without adding auxiliary drugs can bring the medicinal properties of the Heavenly Rank Divine Medicine to the limit, and the effect after finally becoming a pill is indeed as magical as the Heavenly God Ignition.

However, this heaven-level divine medicine without adding auxiliary drugs is also the most difficult to refine, and the requirements for the alchemist's spiritual power and aura control ability are extremely high.

Facing these two kinds of pills, Tian Xu sat quietly and thought for a long time, but he still felt that he was not sure about refining. At this time, Yin Yang Ding couldn't help but say: "Stupid! how can anyone challenge the most difficult pill to refine at the beginning, now that you have unlocked the fourth-level pill, you must always go from easy to difficult, practice first." Do you really think you're a genius?"

Tian Xu thought about it, what Yin Yang Ding said seemed to make sense, so he selected four from the fourth-level Danfang and practiced it first.

The four kinds of pills that Tian Xu chose to practice were the Great Qi Replenishing Pill used to replenish the aura during cultivation, the Great Creation Pill used to heal internal and external injuries of the body, the Ruyi Pill used to heal mental injuries and was far better than the Concentration Pill, and the Xiaoyao Pill used to break through the barriers to cultivation.

Zhou Aiping saw that Tian Xuliang had closed his eyes and was silent for a long time, and he didn't know what he was thinking, so he stopped talking, and also closed his eyes to cultivate and recuperate his injuries.

Zhou Aiping, who was cultivating, was awakened by the sound of Tian Xu tinkering with the pill furnace and elixir. When she opened her eyes, she saw Tian Xu putting out the Nine Xuan Furnace and more than a dozen elixirs one by one. She took a closer look and found that the composition of these elixirs was familiar, and asked, "Is it to refine the Great Qi Replenishing Pill?"

Tian Xu nodded and said, "Yes." I haven't refined the fourth-level pill yet, and the Great Qi Replenishing Pill is relatively easy, so I will use it to practice my hands first. As he spoke, he blended the number of elixirs one by one, made up a large amount of Qi Replenishing Pill, threw them into the Nine Xuan Furnace one by one, and then sat down and meditated, and began to refine the pill.

Tian Xu didn't have his own Danhuo, so he used the aura to urge the Dan furnace and began to refine the aura in the elixir.

Refining, fusing and absorbing the aura in the environment, condensing the pill, building the formation, and doing it step by step, it soon entered the final link. Tian Xu found that compared with the fourth-level pill and the third-level pill, the biggest difference was the total amount of aura and the setting of the formation.

Compared to the third-level Qi Replenishing Pill, this Great Qi Replenishing Pill contained nearly ten times more spiritual energy. When refining the elixir, it requires a much stronger aura control ability than refining the third-level pill, in order to successfully complete the compression and control of the aura, and ensure that the aura will not rebel when condensing the pill and building the formation.

Fortunately, Tian Xu's olfactory imaging could clearly see the details of the aura, and he had enough aura in his huge golden pill to ensure that he could easily control the aura in the Dan furnace that had not yet been locked by the formation, until the process of alchemy was finally completed.

This furnace of Great Qi Replenishing Pill has refined nine, five of the top grade, two of the medium grade, and two of the super grade, which are not bad overall, but Tian Xu is not satisfied. Three states appeared in the same furnace of pills, indicating that his control over the pills was not stable enough.

Tian Xu summed up the shortcomings in the operation of the first furnace, prepared another elixir, and thought about the key points of the operation, so he began to refine the second furnace of the Great Qi Replenishing Pill.

This time, he absorbed the lesson of the first time, focusing on strengthening the control of the stability of the aura when absorbing the aura of the environment, and the effect was very obvious, and six super grades and three top grades appeared among the nine pills.

The practice began to bear fruit, Tian Xu put the two furnaces of pills that had just been refined in a jade box, got up and came to the door of the cave, set up the pot and began to cook. Since he found out that Ziyan was being followed by Humen, he has been tracking Ziyan in a hurry, and he has not had the heart to eat at all, he has not eaten anything for a week, and basically only relies on aura to maintain his body. Now that he saw hope, he finally had the leisure to get himself something to eat.

He also cooks to restore the aura around the cave. After refining two furnaces of the Great Qi Replenishing Pill in a row, a lot of spiritual energy in the vicinity has been absorbed, and the concentration has dropped significantly. Although the aura at the end of this Qinling Mountains is sufficient, it can't be seen compared to the inside of the Medicine King Dou.

Zhou Aiping had been sitting there, silently watching Tian Xu's alchemy. When Tian Xu was refining the pill, he didn't avoid her, which was a sign that he didn't treat her as an outsider. As an experienced alchemist, she knew how difficult it was for Tian Xu to refine these two Great Qi Replenishing Pills. No matter what level of Qi Replenishing Pill is, it is basically the easiest pill of the same level to refine, and it is also the most ideal pill to practice as an introductory practice when starting a higher-level pill refining.

However, Tian Xu was able to successfully refine nine pills for the first time, and the first time he refined a super-grade Great Qi Replenishing Pill, she was still surprised, because when most alchemists tried to refine a higher-grade pill, the number of refining would basically not exceed five, and after becoming a pill, as long as one of them reached the middle grade, it would be considered a success. Tian Xu's results can be said to be very good.

But Tian Xu didn't seem to be satisfied, and it wasn't until the second furnace was refined into six super products that he shook his head and reluctantly agreed with his results, which shows that this little guy's heart is very high. Less than a month ago, Tian Xu also bought several low-grade and low-grade pills from the stall in Shennongmen, and heard that he had just bought a Dan furnace at that time, saying that he wanted to learn alchemy. Well, Tian Xu's talent for alchemy seems to be a little too strong.

Besides, where did he get these pills? These pills seem to be quite a lot, and they are quite good, at least the Mindful Pill is different from the four formulas he knows. "Did he get some Danfang set?" Zhou Aiping secretly guessed.
