Tian Xu thought for a while and said, "That Concentration Pill was just refined by me, and it has been used up. However, the elixir on my body can be refined into four more furnaces, there should be about thirty pieces, and how many of them can be super high-grade, so it's hard to say. In addition, I can also get more than 100 pieces in a week, so there will be no problem, right?" Now the limit for him to refine the Heart Pill is the amount of tiger bone glue. In about a week, he could find a Bengal tiger in the zoo or in the wild, get tiger bone glue, and refine 100 pieces of centering pills.

He ignored Aunt Zhou's surprised expression, and then asked, "Can your recovery be faster, such as using some elixirs or pills or something, or can someone help you?" Now that the Demon Gate has returned, the cultivation world is a little chaotic, and there are Kunlun Sect and Wutai Mountain eyeing Shennongmen, and small sects like Humen dare to make a move against you, you also need to recover your self-protection ability as soon as possible." ”

Aunt Zhou smiled bitterly: "How come I don't know this? It's just that my cultivation is pure mind, and I have suffered spiritual damage, and ordinary pills have little effect on me." I don't have any pills in my hands that are suitable for myself. If there is a turtle breath Yang Yuan Dan, Xianhuang An Shen Dan and the like, it should be able to recover faster, maybe it can shorten the time to one or two months. ”

The two kinds of pills that Aunt Zhou said are all third-level pills, and he also has a pill prescription in his hand, but he doesn't have the main medicine of the Turtle Breath Yang Yuan Pill, and he doesn't have a few very rare auxiliary medicines. However, the main medicine of Xianhuang Anshen Pill is human-level bezoar, which he has, and he can also make up seven or eight other auxiliary medicines, if you add the medicinal materials in Aunt Zhou's hand, it is estimated that it is still possible to refine it.

Tian Xu asked Aunt Zhou: "Isn't there a pill with a better effect?" If you have tiger head scorpion venom there, this Immortal Huang An Divine Pill can be refined. ”

Aunt Zhou was no longer surprised that Tian Xu had any elixir in his hand, or what elixir he would refine, but said helplessly: "I have only heard of this tiger head scorpion, and it is said to be very rare. It's not that there are better pills you said, but the requirements for medicinal materials are too high, and I have only heard of the names of some of them, and I don't even know what the medicinal materials look like, let alone refine them. For example, the Heavenly Bee Requiem Pill and the Xuanyu Creation Pill. ”

Tian Xu had never heard of these two pills, and they should be above level four. He asked Aunt Zhou to read out the Dan Fang, but she didn't know everything. Tian Xu suddenly thought of the egg clip of the tiger head scorpion that he bought from Liu Jucai in the cultivation bazaar, so he took it out and showed it to Aunt Zhou: "This is said to be the egg clip of the tiger head scorpion, which can hatch the tiger head scorpion." I just don't know how long it will take to raise and get scorpion venom. ”

The two sighed relatively, both a little helpless. It seems that he can only honestly go to the ground level snow lotus.

Just when Tian Xu was at a loss, the voice of Yin Yang Ding suddenly came from his mind: "The main medicine of the Heavenly Bee Requiem Pill is the Heavenly Rank Jade Bee Chrysalis and the Millennium Jade Honey, and the main medicine of the Xuanyu Creation Pill is the Heavenly Xuanguo and the Nine-petal Jade Lotus, you have them all in your hands, why are you still worried here?"

Tian Xu said to Yin Yang Ding: "But I don't know Danfang." What level are these two pills, and can I refine them now?"

Yin Yang Ding said disdainfully: "Both are fourth-level pills. Now that you have started alchemy, you should be able to refine it, right? You have never taken the initiative to care about the unlocking of the jade disk, go and take a look. ”

This Yin Yang Ding is also a wonderful, when Tian Xu first came into contact with it, he thought it was a cold artifact with the demeanor of a master outside the world, but he didn't expect that it was just because of the lack of vitality at that time, and it had been sleeping. Since recovering some of his energy in the Medicine King Dou, this Yin Yang Ding has fully demonstrated the essence of a chatterbox, as long as there is a chance, he will chatter endlessly.

After Tian Xu endured it for a while, he left the Yin Yang Ding who kept complaining like a neglected little daughter-in-law, and went to the space to look at those jade plates.

From the previous piles of jade saucers, Tian Xu seemed to have felt the laws of the color of some jade saucers, this time he did not blindly try which pile of jade saucers could be read, but directly set his eyes on the green and blue piles. Sure enough, there were two pieces in the blue jade plate that could be read.

This time is different from the last time after Ning Dan, it is not that the first two pieces will be unlocked after reading the first two, after Tian Xu finished reading the first two jade plates, the remaining four pieces in this pile of cyan jade plates still cannot be opened.

Among the two jade plates unlocked, one is the "Danhuo Theory", and the content of the other is not what Tian Xu expected, it is a fourth-level Danfang.

The Dan Fire Theory introduces various flames that can be used for alchemy. There is no difference between the flames, and all that alchemy needs is the flexible and abundant energy brought by the high temperature in the flames. Compared to Tian Xu's current use of aura alchemy, using Danhuo can save his own aura, and at the same time, it can also give the pill stronger activity. When refining some high-grade pills, the difference in this point was extremely obvious.

In this Danhuo Theory, the characteristics of different types of flames are explained in detail, from the flames of ordinary combustibles burning in the air, to the vibration high temperature generated by the principle similar to the microwave oven, to the infrared heating produced by condensing sunlight, and the various aura flames created by cultivators using Reiki operations. Through these introductions, Tian Xu clearly found that the aura flame had obvious advantages.

After Tian Xu learned about these different Danhuo, he found that the effect of these Danhuo was essentially the same as his direct use of aura control to refine Dan, but it was just a little more convenient. The aura flame in it is very difficult to condense and cultivate, but it is the most convenient when it is used, and there is no need to be distracted to control it at all, you can flexibly and accurately control the temperature in the Dan furnace, and even form a complex temperature field in the Dan furnace to facilitate the needs of alchemy.

The aura alchemy he is using now is still significantly different from the aura flame, and it can be said that it is not the same exercise at all. He didn't have a ready-made Dan Fire to cultivate now, and if he wanted to have his own Aura Flame, he needed to find a suitable flame technique to cultivate, or simply create a flame technique of his own.

Legend has it that the Samadhi True Fire used by Taishang Laojun in alchemy is actually a special flame created by a relatively clever spiritual power. The properties of this flame can be adjusted to better suit the properties of different elixirs, helping to tame some high-level elixirs with intelligence.

The number of these fourth-level pills far exceeded Tian Xu's expectations, and they were even more than the most basic of the first three levels combined, reaching more than three hundred, and the functions of these pills covered almost all aspects of cultivation. The Heavenly Bee Requiem Pill and the Xuanyu Creation Pill that Tian Xu cared about the most were among them. In addition, the honey grass immortal lotus pill that is crucial to the purple smoke is also among them.
