Although the general purification method can also achieve this process, it requires a long time of practice to achieve. And not everyone can do it, otherwise the alchemists would not be divided into high and low levels.

Incineration of the liquid medicine with fire will not destroy the active ingredients of the liquid as a whole, but it will also lose at least 30% of its efficacy. In other words, this method is also harmful to the effective ingredients.

Luo Tian's method is different, he uses a similar method to the extraction method, but this purification method is very difficult to do. Only a guy like Luo Tian, who often creates a miracle, can do it.

This method is very simple to say, but it is impossible to control the true qi while looking inward, which is simply impossible in the eyes of ordinary people. This is a dual-purpose method, and many people must concentrate to achieve internal vision, so this method is only effective for Luotian.

"If you are really a genius in alchemy, it is a pity that you still need to transform the true qi attribute to do so, otherwise you will grow into the top alchemist in the Xuanyuan Continent. By the way, how is your Mu Zhen Qi transformed?" Tong Lao praised in amazement.

It seems that his apprentice will eventually rise, and when the time comes, everyone will ask who his mentor is, and Tong Lao will also feel very proud. "It's a pity that I can't see that day," Tong Lao said regretfully in his heart, he really wanted to see what Luo Tian's future looked like.

"Master, why are you suddenly unhappy, is it that the apprentice has made you angry?" Luo Tian saw that he had completed his goal, and Tong Lao felt a little sad, so he asked.

"It's nothing, it's just that for the teacher, I'm afraid I won't see the day you grow up, so I'm a little sentimental! Tong Lao waved his hand again and again, but Luo Tian knew how much Tong Lao wanted to accompany him to grow up.

"Master, is there really no way to heal your injuries? Isn't there still more than ten years left?

"Alas, ordinary pills could not suppress this injury. Unless someone above the alchemy master refines a pill for the teacher, it is possible to suppress it temporarily!However, it is an eight-rank elixir, where is it so easy to refine!" Tong Lao said helplessly.

A high-level alchemist can refine more than seven grades of pills. However, most of them will be stuck in the Seven Pins Pill and cannot be entered. The pills that can refine the eight grades will be called alchemy masters, and they are the top storage in the entire alchemy!

"Eight-grade elixir, this is very difficult, the apprentice is not even a first-grade alchemist yet. It's okay Master, when I become a first-grade alchemist, I will go to the Dan League and ask those masters to let them refine the elixir for you, Master!

"Ahem, you stupid boy, do you know the value of the eight-pin pill, just talk nonsense about what pill you want to ask for for the teacher. Tong Lao coughed and explained to Luo Tian helplessly.

The elixir is of great significance to the monk's practice. Like the True Yuan Pill that Luo Tian was given by the Lord of the Dust Cloud Country last time, it was an elixir that helped people break through the True Yuan Realm. Generally speaking, there is only a thirty percent chance of breaking through the True Yuan Realm on your own.

If you fail to break through the first time, it will cause a lot of backlash to the body. Then it will be more difficult to break through next time. And one pill of True Yuan Pill can increase the chances of success by forty to fifty percent. It can be seen how powerful the effect of the elixir is.

This is just a top-notch elixir. The number of pills above four grades is very rare. The elixir above the sixth grade is even more precious and abnormal. Not only is it extremely difficult to find the required materials, but even the probability of success in refining is greatly reduced. Eight pins of elixir, that is the best elixir that you may not have seen for hundreds of years!

Hearing Tong Lao's explanation, Luo Tian was also scared stupid. It turns out that the pill with more than four grades is very precious. The success rate of the sixth grade or more is very low? Doesn't that mean that the eighth-grade elixir is basically hopeless?

"No matter what, Master, don't worry, the apprentice will definitely find the elixir for you! Now the apprentice must first reach the first-grade alchemist. Luo Tian made up his mind, when he reached his goal, he would go to the family first, and if he made sure that his father was okay for the time being, then he would go to find the best elixir for the master!

In the following time, Tong Lao instructed Luo Tian more strictly. In Tong Lao's opinion, Luo Tian is a good seedling to become a senior alchemist, but he can't destroy it in his own hands. Therefore, he passed on all his experience to Luo Tian without reservation.

Tong Lao also wrote a book for Luo Tian, which included all his experiences in alchemy, and even included some experiences of high-grade pills. Although it is useless to Luo Tian for the time being, at the very least, when Luo Tian grows into a higher alchemist in the future, it will be of great help to him.

Luo Tian is now in the stage of curdling. Because he had just completed the cultivation of the purification stage, Tong Lao first let him stabilize for a few days before starting the next stage. In the past few days, Tong Lao and Luo Tian have refined a lot of high-purity medicinal liquids, in order to cultivate the condensation powder in the future. Curling powder is also called curing. This is the process of turning the liquid active ingredient into a powdered active substance, and this is the case!

The solidification stage is still much simpler than before, but this requires more true qi output from the alchemist. The alchemy furnace became particularly important at this time. Tong Lao used the most ordinary Dan furnace for Luo Tian, and the flame of this Dan furnace is also an ordinary flame. Therefore, it can support the refining of a first-grade elixir at most, but this is enough for Luo Tian.

This ordinary Dan furnace has a disadvantage, that is, the consumption of true qi is very large. The alchemist should not only use the true qi to control the purified medicinal liquid, but also use the true qi to control the size of the flame. Let each other reach a state of balance. In this way, the liquid can be cured slowly!

Luo Tian couldn't support it at the beginning. The main reason is that his Mu Zhizhen Qi is not large, and although it has been transformed for such a long time, it can only be supported once. In other words, Luo Tian's refining of the pill must be done in one go. Otherwise, after failure, it will take a long time to wait for the next time Mu Zhen Qi is full.

This time, he did not succeed in refining the solid medicinal powder, and failed because of the lack of Mu Zhen Qi. But he wasn't discouraged. After a period of recovery, Luo Tian finally accumulated a lot of wood element true qi. Sure enough, this time Luo Tian directly turned those liquid medicinal liquids into medicinal powder.

"Master, I succeeded!" Luo Tian happily took the handful of medicinal powder and showed it to Tong Lao.

"Well, that's right, it's really making rapid progress, so it seems that it's just the last step to gather Dan! This is also the most important and difficult step! In addition to the need to consume a lot of true qi, the proportions of fusion must be mastered. I'll show you a demonstration first, and you'll be on the sidelines. Let's see if you can experience it!" said Tong Lao, and began to refine the pill by himself.

When it came to Judan, Luo Tian was full of spirit, and he wanted to see what "Judan" was called in a short period of time.

When it was time to gather Dan, Tong Lao deliberately slowed down his speed, in order to let Luo Tian observe better. I saw Tong Lao wrapping the medicinal powder with a large amount of true qi, and then I saw the powder dancing up and down in the Dan furnace. This is due to the fact that Tong Lao Zhen Qi Control zhì.

After a long time, Luo Tian found that the powdered pill slowly began to polymerize. At first, it was just a small pill, and then the nearby powder began to adhere to it, and at this moment, Tong Lao suddenly increased the intensity of rotation, so that many powders began to rotate around the pill at high speed. And the flames of the Dan furnace below suddenly turned into a raging fire.

Luo Tian looked at Tong Lao's superb skills, and he was simply amazed. He had never seen alchemy turn out to be a process of enjoyment. The true qi wrapped the medicinal powder and spun for a long time, until finally, I saw Tong Lao suddenly remove the true qi that controlled the fire of the Dan furnace, and then the flame instantly became smaller.

I saw that a spherical pill was still spinning rapidly, and Tong Lao slowly slowed down the rotation. In the end, I saw a gray pill the size of a soybean, appearing in the very center of the Dan furnace. At this moment, the alchemy is complete!

Tong Lao handed the freshly refined pill to Luo Tian, he only felt that this pill still had residual warmth! This was an unknown pill, or it had no medicinal effect. This pill was just a matter of hand, but Luo Tian felt that it was very difficult to complete.

At the moment of Judan, it was also the moment when the consumption of true qi was the most intense, so Luo Tian first had to transform a large amount of wood attribute true qi. The powder is then heated evenly so that it forms small pieces.

It also consumes more True Qi, while making the powder rotate around the center, and increasing the intensity of the flames. It's a tough balance to master.

Finally, it is also important to abruptly withdraw from the flames. That would allow the elixir to cool down instantly. If the flame is slowly weakened, it is very likely that the elixir will not be able to form a form. It is possible to fall apart, or it can be broken into several pieces.

After Tong Lao's demonstration, he asked Luo Tian to start practicing how to gather pills! Tong Lao had prepared a lot of medicinal powder before, so it was enough for Luo Tian to use. However, Luo Tian wasted these medicinal powders in just one month. Waste means not succeeding once!

Today, Luo Tian failed again, and with a "bang", he blew up the Dan furnace again. Generally, after the failure of Judan, a large amount of energy will be released from the pill. That energy could completely destroy the Dan Furnace. Because the process of alchemy is the process of activating the medicinal effect. Judan, on the other hand, brings together the power of this medicinal effect. It's not just a simple fusion, it's a change in energy.

This is just an ordinary first-grade pill, if it is a higher-grade pill refining failure, it is very likely that Luo Tian's entire person will be blown out. From this point of view, alchemists are also a dangerous profession! Especially high-level alchemists, when refining high-grade pills, if they don't control it well, they will be killed directly. The power of that high-grade elixir is not comparable to the elixir of this product.

Listening to Tong Lao, some pills exploded more powerful than the Thunder Fire Bead. Luo Tian sighed after hearing this, it was really dangerous. During this time, Luo Tian has also been bombed many times. Every time, I walked out of the alchemy room with a dark face!
