The Hundred Poisons Return to One Pill is a fourth-level pill, and the difficulty of refining is medium, so it is not too difficult. Tian Xu checked the pill recipe of 100 poisons and returned to one pill, and found that there were more than ten main drugs of this pill, all of which were highly toxic drugs above the human level. Dozens of excipients are needed. The main medicine can be adjusted somewhat, and there are more than 20 kinds of Dan prescriptions that can be changed. After the combination of different poisons, supplemented by the corresponding excipients, the final detoxification effect is different.

He first chose the best formula for this passion cat toxin, and inspected the elixir in his hand, his tiger tail scorpion, incorruptible vulture dove pill, golden stone fungus, soul devouring centipede, etc., all have to be used, and the main medicine is still five kinds. As for the auxiliary medicines, they are all ordinary drugs of the more common elixir, but they are easy to get together. So he said to Liu Jucai: "For this toxin, there is a hundred poisons that should be effective. It's just that this pill recipe for a hundred poisons is too complicated, and there is a lot of medicine in my hand, I don't know if you can get it together?"

Liu Jucai and Hou Guoqiang asked at the same time: "What is missing?" Hou Guoqiang even said: "There are dozens of pills in one poison, and there are only two of them in my hands, and the medicines have never been made up, and they have never been refined." Let's try it with you this time, if you can refine one, this fourth-level detoxification elixir will probably alarm the entire cultivation world. ”

Seeing that Hou Guoqiang agreed happily, Tian Xu immediately listed the elixir needed. Sure enough, as he expected, the auxiliary drugs are complete, and of course the giant viper and human-level bezoar in the main medicine are sold by him, and there are also unintentional strychnine and human-level aconitum, only the devil Epiphany Kitado has no stock. This is also in Tian Xu's expectations, the devil epiphany is extremely rare, and it generally takes several years to bloom once, each flowering is only a few minutes, if you want to pick, you must complete it in these minutes, and quickly complete the initial processing, otherwise the medicinal effect will soon be lost. Moreover, the petals of the devil's epiphany were covered with sharp spikes, and the thorns were extremely poisonous, and it was very difficult to pick and process.

However, the missing devil Tanhua Tian Xu has a way, he can replace it with the bee needle on the jade bee chrysalis. There are many similarities in the toxicity of the two, at least in this Hundred Poisons Guiyi Dan, there is not much impact.

The elixir is ready, and Tian Xu wants to prepare a place for alchemy. Fortunately, Hou Guoqiang usually wants to refine Dan, and there is a specially built Dan room here. There are ready-made spirit gathering formations around the Dan room to replenish the aura required for alchemy. The aura around Geshi is insufficient, and if there is no spirit gathering formation, there is no alchemy at all.

Tian Xu went to feel the concentration of aura in the Dan room, which was barely able to meet the requirements of alchemy. Limited by the surrounding environment, although it is not ideal, he can only make up for it.

Although the formula of this hundred poisons is complicated and there are many elixirs, the control required for refining is not too difficult, Tian Xu honestly configured an elixir, put a kind of farming into the Nine Xuan Furnace, and raised the Dan Fire to start refining. Refining the medicinal power, fusing the aura, condensing into a pill, depicting the formation, and doing the operations step by step, in less than half an hour, a furnace of pills was refined.

After extinguishing the fire, waiting for the vibration of the pills in the furnace to stop for a while, Tian Xu opened the lid of the furnace, and twenty-seven pills from the furnace jumped out of the furnace in a line. There was a dazzling flow of colors on each pill, and all of them were super grade pills, which made Tian Xu admire himself very much, and this furnace of pills was quite successful.

Putting the pills into the prepared porcelain bottle, Tian Xu put ten of them into his space, and left the remaining seventeen outside, ready to take them to Liu Jucai. The other two elixirs, he honestly and unceremoniously put them away.

It's not that he's a fan of money, he doesn't look down on most of these medicinal materials, but the unintentional strychnine and human-level aconitum are not in his Medicine King Bucket, and they all retain their activity, leaving these medicinal materials can just enrich the elixir species in his Medicine King Bucket, of course he will not let go of such an opportunity.

Besides, when an alchemist refines an elixir, the proportion of two or three furnaces succeeding in one furnace can already be regarded as a relatively high success rate. It is very rare for almost every furnace to be successful, and most of the refined ones are super pinned pills. He also has to maintain a little mystery in front of people, and of course he can't go out too much.

Tian Xu didn't want to get out of the Dan room too quickly, and he didn't want to refine the Dan anymore, so he took out the knife he had just gotten from Fang Jing, slowly infused the aura, experienced the characteristics of this knife, and became familiar with its use.

He found that the ability of this knife to accommodate the aura, the ability to transmit, and the ability to conduct his operation are very strong, in the stage of gathering qi, because the cognition and control ability of the aura is still relatively weak, may not be able to appreciate the advantages of this knife, once you enter the realm of Ning Dan, after picking up this knife, you will immediately feel that the aura is extremely obedient in it, sending and receiving freely, and it is extremely easy to use.

In the simulation exercise, with the exploration of the characteristics of this knife, he gradually realized the use of the five knife techniques, as well as the three knives and one move of Ku Ding who had just touched the door, and found that the power of each knife technique increased a lot compared to the original use of the thin knife, which made him overjoyed.

After practicing for about an hour, he estimated that the time was almost up, so he put away the Nine Xuan Furnace and the new knife, picked up the Hundred Poisons Guiyi Pill prepared for Liu Jucai, opened the door of the room, and walked out.

As soon as he came out of the Dan room, Tian Xu was taken aback. Liu Jucai, Ah Xiong, Hou Guoqiang, Fang Jing and two Ning Dan masters he didn't know were all guarding the door. He hurriedly asked, "What's the matter? Why is everyone staying here? Is something wrong?"

Liu Jucai said: "Nothing happened, it was the wounded from the Wudang faction who sent it over." The two people in the Ning Dan Realm can still hold on, and those few Qi Gathering disciples may not be able to hold on for long. ”

Tian Xu hurriedly said: "The pill has been refined into a furnace, let's go, let's go see the wounded." ”

Ah Xiong led the way in front, and the group came to a large room in the backyard. A row of nine people lay on a large kang in the middle of the house, all in a coma. Tian Xu used his aura to check the situation of these wounded, and found that the seven injured people in the Qi Gathering Realm were all on the verge of life and death, no wonder Liu Jucai was so anxious. It is estimated that the sons of his worldly friends must be among the seven.

Tian Xu walked up to a Qi Gathering disciple who was in a slightly better condition, stretched out his hand and gently pressed on the person's chest, and very clearly felt that the aura in this person's body was being driven by the toxin, carrying out irregular vibrations, and the organs in his body could not be affected by this vibration, and slowly began to fail. Especially in his sea of consciousness, he was even more confused by this shock, which was the main reason why these people were unconscious.
