"The fourth-grade soul-raising grass of human rank, the third-grade moon-shang flower of human rank, the third-grade green jade lotus..." Dozens of medicinal materials were carefully selected by Wang Kai from the mountains of heaven and earth treasures, and then they were gently placed on an exquisite round jade plate.

"Let's start! Chaos Mountain and River Cauldron, come out!"

Wang Kai thought, and purple soul power gathered in front of him. The next moment, the ancient Chaos Mountain and River Cauldron appeared in front of him. Immediately, his soul power was stimulating, and the fourth red soul ring behind him lit up!

"Three Thousand Burning Sky Flame!"

A purple-black flame flashing with strange light appeared at the fingertips of Wang Kai's right middle finger. Then he waved his hand gently, and the Three Thousand Burning Heaven Flames penetrated into the Chaos Mountain and River Cauldron.

The alchemy furnace and the alchemy 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 elixir and the best elixir fire!

For Wang Kai, his Chaos Mountain and River Cauldron is mainly made of a trace of wild energy born from the universe, and is made of ninety-nine rare god-level treasures, and can naturally be regarded as the most perfect alchemy furnace. In addition, the three thousand burning sky fires he used to refine alchemy are also the dream of countless alchemy masters. When the two are combined, Wang Kai will undoubtedly add wings to his tigers and help him when refining alchemy.

Feeling the temperature that had reached the most perfect in the Chaos Mountain and River Cauldron, Wang Kai gently waved his right arm and a soul power hit the jade plate. The next moment, a soul-raising grass was wrapped in Wang Kai's soul power, flew up from the jade plate, and then came straight above the Chaos Mountain and River Cauldron.

Soul-raising grass is a unique herb that grows in the most yin and wet places, which is extremely precious. For Soul-raising grass, just by smelling its fragrance, it has a magical effect of refreshing the mind. If you can take the whole plant, it can also enhance the spirit and power of the soul master and is also the main material for refining Soul-raising pills.

On Douluo Continent, the soul-raising grass may be almost extinct, and even in the angel secret realm where the soul power concentration is much higher than that of Douluo Continent, Wang Kai only found five soul-raising grasses, which is enough for him to refine the five furnace soul-raising pills.

The soul-raising grass began to melt gradually as soon as it approached the Chaos Mountain and River Cauldron. Under the control of Wang Kai's mental power, in less than a minute, the soul-raising grass was burned into a dark green medicinal liquid the size of half a fist, slowly rolling in the flames, constantly emitting bubbles, reflecting a faint luster.

This is the first step in refining elixirs, tempering and purifying medicinal materials. However, Wang Kai has only completed half of the first step - tempering. If you want to refine truly high-quality elixirs, you must purify the tempered elixirs again to remove impurities that are harmful to the human body. Generally speaking, the greater the purification force, the less impurities the elixir will be in the final refining, and the better the efficacy of the medicine after taking it.

Wang Kai was concentrating on controlling the temperature of the flames in the Chaos Mountains and Rivers Cauldron. At this critical moment of purifying the medicine liquid, the temperature of the flame must not be any error. Otherwise, the effect of the medicine will be lost at a minor extent. If it is more serious, it may even be completely burned to completely destroy the precious medicine liquid.

A few minutes later, some black impurities suddenly appeared in the dark green liquid tempered by the Soul-raising Grass. Looking at these impurities, Wang Kai nodded slightly and tapped his fingers. The impurities in the medicine liquid began to gather under the control of his mental power and separated from the medicine liquid. After removing the impurities, the remaining medicine liquid also seemed purer and more beautiful.

"It's almost done." After a few minutes, Wang Kai nodded with satisfaction as he observed that there were no black impurities in the medicine liquid. At this time, the dark green medicine liquid, which was originally half a fist, had been purified to the size of a ping-pong ball, but its color became deeper and more breathtaking.

"Next!"

After the Soul-raising Grass was tempered, Wang Kai gently pointed his finger, and the medicine liquid turned into the Soul-raising Grass floated on the Chaos Mountain and River Cauldron. Then he had a thought and four soul powers took the four medicinal materials on the Chaos Mountain and River Cauldron.

As the soul queen, Wang Kai's mental power has already reached the realm of one mind and five uses. Therefore, when refining alchemy, in addition to having to divide a thought to control the fire of three thousand burning sky fires, the remaining four thoughts can actually be tempered by four materials at the same time.

However, Wang Kai owns only five soul-raising grasses, and it is difficult to purify the soul-raising grass, and he is not careless at all. Therefore, he just focused on purifying and tempering the soul-raising grass.

Now, Wang Kai has a lot of other natural and earth treasures needed for the soul-raising pill, and they are not difficult to deal with. In order to save time, Wang Kai naturally chose to use parallel methods to process these pills.

Moon dress flowers, green jade lotus, purple feathered zhi... dozens of treasures of heaven and earth were melted by the three thousand burning flames in front of Wang Kai, forming dozens of balls of medicine of different sizes floating in the air, colorful and beautiful.

"Then we have to start the second step - the mixed medicine liquid!" Looking at the medicinal materials that had been tempered and purified in front of us, Wang Kai nodded with satisfaction, and then his soul power moved slightly, and the dark green medicine liquid transformed into the soul-raising grass floated straight into the middle of the cauldron.

The medicinal liquid formed after mixing the heavenly and earth treasures to form elixir liquid is the second step in the process of refining the elixir. After successfully tempering and purifying the heavenly and earth treasures into the medicine liquid, the alchemist must also mix the appropriate amount of medicine liquid with each other at the appropriate temperature and at a 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 to find the most perfect time to mix the medicine liquid.

Therefore, according to the description in "Introduction to Alchemy", most apprentices who go into and out of the alchemy process only need one or two years to master the techniques of tempering and purifying medicinal materials. However, if they want to further master the skills of mixing alchemy liquid, they may need several years or even ten years of immersion!

Compared with ordinary alchemists, Wang Kai naturally does not have so much time to practice. However, he has exchanged the two inheritances of "Introduction to Alchemy" and "True Explanation of Alchemy", and has a deep theoretical understanding of alchemy. In addition, he also has an auxiliary that can be called a plug-in - Xiaoguang!

For ordinary alchemists, they rely more on the experience gained from long-term practice when refining alchemy, even the alchemist is no exception. However, Xiaoguang can quantify the time and portion of the mixed medicine liquid in the alchemy to truly find the most perfect time and proportion!
