Dan Qingzi selected four medicinal herbs from these spiritual materials: Tongmai Grass, Huangkui Vine, Ji Yasi, and Baifeng Grass, and said to Li Yuan: "These four spiritual herbs are the materials for refining Tongmai Dan, one copy of each, and you can refine up to sixteen Tongmai Pills.

Any kind of elixir, in terms of quality, can be divided into lower grade, middle grade, upper grade, best grade, perfect quality, of course, there are some higher qualities, for the time being, you don't need to know. The price difference between each product is double to ten times, although if there are special circumstances, the price will be higher. ”

Li Yuan silently calculated in his heart, these four medicinal materials, more than 30,000 taels of silver, if refined into pills, each pill would be sold for at least 100,000 taels, and sixteen pills would be 1.6 million taels. Earn a lot.

Dan Qingzi asked Li Yuan to take these four medicinal materials, walked into the door of copying, and copied many copies of each medicinal material. Then he said to Li Yuan: " The main function of Tongmai Dan is to open up the meridians, Tongmai grass is the main medicine, the remaining three are auxiliary medicines, the refining process is to first refine Tongmai grass, and then refine Huang Kui vine, after purifying the liquid medicine of these two medicinal materials, first fuse them together, and then refine Ji Yasi into a medicinal liquid, purify, and then wrap it with the fusion liquid of Tongmai grass and Huang Kui vine, and finally refine and purify the white wind grass, after purification, it is necessary to pour the liquid of the white wind grass on the other three medicinal liquids at the fastest speed, and use the alchemy method to make these four medicinal liquids combined. When combined, the spiritual power should penetrate deep into the depths of each drop of medicinal liquid, and the speed of the penetration of white wind grass is the most important factor in refining success or failure and the quality of the elixir. Among them, the level of alchemy techniques and the proficiency of their use are the most important factors in the quality of the refined elixir.

Therefore, alchemy, even with the most advanced alchemy techniques, depends on the proficiency of the application, even if people are very talented in alchemy, they must practice for a long time. Therefore, alchemy, adult practice is indispensable. ”

Li Yuan took out the Qiankun Bagua Furnace, and Dan Qingzi said: "The Alchemy Furnace is also the most important factor in the success or failure of alchemy and the quality of the elixir. This Qiankun Bagua Furnace, although the damage is serious, but the damage is mainly on the periphery, the impact on alchemy is not very large, or the impact on the refining of low-grade pills is not great, as for the functions damaged, this is useless for the time being, and when you may repair this alchemy furnace in the future, I will tell you more powerful functions of this furnace. Now what you need to know is how to use this gossip furnace and how advanced it is compared to other furnaces. ”

Dan Qingzi said, "Now you enlarge this stove and take out the lid of the stove." ”

Li Yuan enlarged the stove, and then probed with his divine thoughts, and found that in a space inside, there was a furnace lid, and Li Yuan moved his thoughts and took out the furnace lid.

Dan Qingzi looked at the lid of the furnace and said, "This lid is intact! With this lid, you have one more weapon." There is a huge space in the lid of this furnace that can trap people, hold things, and turn into a shield to fend off attacks. Now the most useful thing for you is that this lid can be made bigger and heavier, and if you fight the enemy, you just need to make this lid bigger and heavier, and then cover it from a high altitude, and the people below, 108,000, can be stoned to death in one fell swoop. There is also space in this, if your mental power is strong enough, as long as you move your mind, you can take the other party in, and then let you slaughter it. Of course, all this is based on the fact that your spiritual power must be strong, if the opponent's martial arts cultivation spiritual power is much stronger than yours, you will have no way to do it against the other party. If your mental power is not strong enough, you can't make this lid heavier, bigger, and not fast enough to smash out, generally speaking, this cover can trap and kill opponents of the same big realm. In other words, if you are a martial artist, even if you are a first-level martial artist, you can take out an opponent of the ninth level of the martial artist. But if you run into an opponent at the level of a martial king, you may not be able to help the opponent, but with this cover, the other party can't help you, they can't break through your defenses, and they can only dodge your attacks. If the opponent's cultivation is two great realms higher than yours, then you can only flee for your life. Therefore, as long as your cultivation can break through the martial arts, in this mortal realm, you will have very few opponents. Try probing the lid with your mind. ”

Li Yuan probed the lid of this furnace with his divine thoughts, and found that there was a huge space inside, but Li Yuan's spiritual power was not strong enough, and he could only detect a small range, and he could not explore it from a distance.

Chi Yunzi said: "Your spiritual power is low, and you can't feel much space, but when your mental power is strong in the future, you can explore a larger space." Perhaps, what kind of treasure does the Sky Devouring Emperor store inside? ”

Li Yuan said: "Didn't I refine this gossip furnace with blood, why can't I fully master it?"

Chiyunzi said: "This is an innate spirit treasure, how can it be completely mastered with a drop of blood refining." Dripping Blood Refining is just a connection with your Divine Thoughts, branded with your spiritual imprint, which others can't have, use Divine Thoughts to explore the space inside, and can't use it freely. ”

Dan Qingzi said: "There are 108,000 independent spaces inside this Bagua Furnace, and when alchemy, as long as your spiritual power is strong enough, you can put each medicinal herb in an independent space to refine, and then fuse and synthesize. It is also possible to treat each small space as an independent alchemy furnace, refining 108,000 kinds of pills at the same time. Of course, this requires your spiritual power to be extremely strong, otherwise, it is impossible for you to refine two pills at the same time, and even, it is impossible for you to refine two medicinal materials at the same time, just like you now, your spiritual power is too low-level, so you can't refine two medicinal materials at the same time.

A low-level alchemy furnace is extremely mentally draining when alchemy. It may be that your spiritual power has been exhausted before you have begun to participate in the medicinal materials, but this Dan furnace not only does not consume your spiritual power, if you have enough energy to fill the internal space of the Dan furnace in the future, it can also enhance your spiritual power. Of course, now you can't use this feature, its space is damaged. ”

Li Yuan followed Dan Qingzi's teachings and began to practice over and over again.

Chi Yunzi said: "Practice hard, and when you refine this Tongmai Pill, I will send back a few hundred pieces to your Li family, so that the young people of the Li family can open up the meridians, add many masters, and no longer be afraid of the Cao family." ”

Dan Qingzi said, "And this replenishing Yuan Dan, when you refine it, send it back to your mother, as long as you have one, your mother's body can recover."

Your brother is in urgent need of the Bone Pills now, you practice hard, among the herbs you bought this time, there are herbs needed to refine these two pills, and when you learn to refine these pills, you can refine some and send them back to your mother and brother, as long as they have these pills, their physical injuries will be cured immediately. ”

Chiyunzi said: "Your ancestor was bitten by a seven-step snake, and if you want to be cured, you need the second-level elixir Lingzhi Melting Poison Pill. And your brother, the meridians are broken, and what you need is also the second-level pill Continuation Pulse Pill, you promised Lin Taiqing that the tonic pill is also a second-level pill, you have to practice hard, improve your cultivation as soon as possible, improve your mental strength, and be able to refine the second-level pill as soon as possible, so that you can refine the pill for them. ”

Dan Qingzi said: "If an ordinary person wants to refine a second-level elixir, his spiritual power must reach level 20. However, Li Yuan's spiritual power is particularly strong, and it is estimated that as long as his spiritual power reaches level eleven or above, he will be able to refine second-level pills. ”

Li Yuan said: "Okay, I must practice hard! It's just that if I use the Chaos Flame to practice, will it consume too much energy of the Chaos Flame and use the Chaos Flame badly?"
