"Human-level fourth-grade soul nourishing grass, human-level third-grade moon flower, human-level third-grade green jade lotus......" Dozens of medicinal materials were carefully selected by Wang Kai from the mountains of heavenly and earthly treasures, and were immediately gently placed on a delicate round jade plate.

"Let's get started! Chaotic mountains and rivers, out! ”

Wang Kai's heart moved, and the purple soul power gathered in front of him, and the next moment, the quaint chaotic mountains and rivers appeared in front of him, and in an instant, his whole body was full of soul power, and the fourth red soul ring behind him lit up!

"Three Thousand Burning Sky Flames!"

A wisp of purple-black flame with a strange brilliance appeared on the tip of the middle finger of Wang Kai's right hand, and then with a slight wave of his hand, the three thousand Burning Sky Flames went straight into the Chaos Mountains and Rivers.

Dan furnace and Dan fire are undoubtedly the most important hardware facilities for alchemists! If an alchemist wants to refine the best elixir, he must have the help of the best Dan furnace and the best Danhuo!

For Wang Kai, his Chaos Mountains and Rivers Ding is based on a trace of Hongmeng Qi born from the universe as the main material, and is made into an artifact with ninety-nine rare god-level heavenly and earth treasures, which can naturally be regarded as the most perfect alchemy furnace; In addition, the three thousand Burning Heavenly Flames he used for alchemy were also the strange fires of heaven and earth that countless alchemists dreamed of, and the combination of the two undoubtedly made Wang Kai feel like a tiger with wings when refining pills, like divine help.

Feeling that the chaotic mountains and rivers had reached the most perfect temperature, Wang Kai waved his right arm slightly, and a soul power hit the jade plate. The next moment, a soul-nourishing grass was wrapped in Wang Kai's soul power, flew up from the jade plate, and immediately came straight to the sky above the Chaos Mountains and Rivers.

Soul Nourishing Grass, a strange herb that grows in the most yin and wet places, is extremely precious. For the soul nourishing grass, just smelling its fragrance has the miraculous effect of refreshing the mind, if you can take the whole plant, it can also improve the spiritual power of the soul master, and it is also the main material for refining the soul nourishing pill.

On the Douluo Continent, the Soul Nourishing Grass may be close to extinction, and even in the Angel Secret Realm, where the concentration of soul power is much higher than that of the Douluo Continent, Wang Kai has only found five Soul Nourishing Grasses, which is enough for him to refine the Five Furnace Soul Nourishing Pill.

As soon as the Soul Nourishing Grass approached the Chaos Mountains and Rivers, it began to melt gradually, and under the control of Wang Kai's spiritual power, in less than a minute, the Soul Nourishing Grass was calcined into a dark green medicinal liquid the size of a small half a fist, slowly rolling in the flames, constantly bubbling and reflecting a faint luster.

This is the first step in refining the elixir, refining and purifying the medicinal materials, however, Wang Kai has only completed half of the first step - quenching, if you want to refine a truly high-quality elixir, you must purify the quenched heavenly materials and earth treasures again to remove the impurities that are harmful to the human body. Generally speaking, the greater the purification strength, the less impurities will be in the final refined pill, and the better the efficacy will be after taking it.

Wang Kai was engrossed in controlling the temperature of the flames in the Chaos Mountains and Rivers, at this critical moment of refining the medicinal liquid, the temperature of the flames must not be the slightest mistake, otherwise, the medicinal effect would be lost, and if it was serious, it might even directly incinerate the precious and incomparably precious liquid.

After a few more minutes, some black impurities suddenly appeared in the dark green liquid quenched from the soul nourishing grass, looking at these impurities, Wang Kai nodded slightly, his fingers tapped, and the impurities in the medicinal liquid began to converge under the manipulation of his spiritual power, and separated from the medicinal liquid, and after the impurities were removed, the remaining medicinal liquid also appeared more pure and beautiful.

"Almost." After a few more minutes, observing that there were no more black impurities in the liquid medicine, Wang Kai nodded with satisfaction, at this time, the dark green liquid liquid that was originally half the size of a fist had been purified to the size of a ping-pong ball, but its color became more profound and moving.

"Next!"

After the soul nourishing grass was refined, Wang Kai bent his fingers lightly, and the medicinal liquid turned into the soul nourishing grass floated on the Chaos Mountains and Rivers Ding, and then his mind moved, and the four soul powers took the four medicinal materials to the Chaos Mountains and Rivers Ding.

After advancing to the Soul King, Wang Kai's spiritual power had already reached the realm of one heart and five uses, so when refining the pill, in addition to having to separate one mind to control the fire of the three thousand Burning Sky Fires, his remaining four thoughts could actually be tempered with four materials at the same time.

However, there were only five soul nourishing grasses owned by Wang Kai, and it was relatively difficult to purify the soul nourishing grass, so he was not careless at all, so he just concentrated on purifying and refining the soul nourishing grass.

And now, for the other heavenly and earthly treasures needed by the Soul Nourishing Pill, Wang Kai has a lot of them, and they are not very difficult to deal with, in order to save time, Wang Kai naturally chooses to use a parallel way to deal with these Dan materials.

Moonflower flowers, green jade lotus, purple feather mushroom...... Dozens of heavenly and earthly treasures were melted by the three thousand burning heavenly flames in front of Wang Kai, forming dozens of clusters of medicinal liquids of different colors and sizes floating in the air, colorful and very beautiful.

"Then it's time to start the second step - mixing the liquid!" Looking at the medicinal materials that had been quenched and purified in front of him, Wang Kai nodded with satisfaction, and then his soul power moved slightly, and the dark green medicinal liquid turned into soul nourishing grass floated straight to the middle of the Great Ding.

The formation of the elixir formed after mixing the heavenly materials and earth treasures to form the elixir is the second and most critical step in the process of refining the elixir. After successfully refining and purifying the heavenly materials and earth treasures into medicinal liquids, the alchemist must also mix the appropriate amount of medicinal liquids with each other at the right temperature and at the perfect time, so as to obtain the prototype of the elixir - the elixir.

Compared with the first step, the second step of alchemy is undoubtedly more difficult, because it requires the alchemist to have strong mental power and long-term practice before he can find the perfect time to mix the medicinal liquid.

Therefore, according to the description in the "Introduction to the Dan Dao", most apprentices who enter and exit the alchemy journey only need one or two years to master the technique of refining and purifying medicinal materials, but if they want to further master the skill of mixing the Dan liquid, they may need years or even ten years of immersion!

Compared with ordinary alchemists, Wang Kai naturally doesn't have so much time to practice, however, he has already redeemed the two inheritances of "Introduction to Dan Dao" and "True Solution to Dan Dao", and has a deep theoretical understanding of alchemy.

For ordinary alchemists, they rely more on the experience gained from long-term practice when they are alchemists, even alchemy masters are no exception, but Xiaoguang can quantify the time and amount of mixed medicinal liquid in alchemy, and truly find the most perfect timing and proportion!

"Xiaoguang, turn on the alchemy assist mode!" Wang Kai silently commanded in his heart, and in an instant, his soul power moved, and the blue-green medicinal liquid transformed by the green jade lotus approached the dark green medicinal liquid turned into the soul-nourishing grass.
