Zhang Ye Lingjue clinged to the Dan furnace, feeling that the temperature in the Dan furnace had reached a suitable level, his mind moved slightly, and he opened the lid of the Dan furnace.

"Whoosh-"

Zhang Ye Shi exhibited the technique of scattering flowers by the Heavenly Maiden, and threw the dolls into the Dan furnace.

The higher the quality of the pill, the more herbs are needed. For example, refining the third-grade true pill requires only three hundred and sixty kinds of medicinal materials, while the second-grade true pill requires seven hundred and twenty kinds of medicinal materials.

Of the seven hundred and twenty kinds of medicinal herbs, there are seven hundred and twenty regiments of medicinal liquid. When these medicinal liquids are put into the Dan furnace, you must remember the order, and you must not mess up. Otherwise, if the medicinal properties are opposite, the liquid will collide together, and the small one will not be able to fuse well, and the alchemy will fail, and the large one will have a medicinal conflict, and the Dan furnace will explode.

Ten ...... One hundred ...... 300 ...... 500 ...... Seven hundred and twenty kinds.

It took Zhang Ye two hours, and finally put the seven hundred and twenty kinds of medicinal liquids into the Dan furnace one by one. Although the whole process was extremely hard, it was completed smoothly, and the seven hundred and twenty kinds of medicinal liquids were slowly fused.

After successfully dispensing the liquid medicine, the next key is to use the alchemy technique to fuse the control of the elixir and the flame.

The control of the flames is carried out by the fire spirit. The fire spirit and Zhang Ye have the same thoughts, and Zhang Ye only needs to move his thoughts slightly, and the fire spirit can make adjustments to the flame as soon as possible.

While the fire spirit controlled the flames, Zhang Ye began to cast the third transformation of the stars. Zhang Ye used to cast the third transformation of the stars, using the Three Yang True Fire and the Dead Wood Spring Technique, and the two exercises were used at the same time, although he could also smoothly refine the elixir, but he always felt a little unnatural.

Now, Zhang Ye directly used the power of the five elements, and he felt extremely smooth when he landed. Although the power of the five elements contains the five kinds of origin liliang, the five kinds of liliang are integrated, and there is no trace of unnatural exertion. Driven by the power of the five elements, the third transformation of the stars has been cast more smoothly, and the control has also improved a lot.

Zhang Ye was overjoyed. The power of the five elements combined with the third change of the stars really had an unexpected effect, so it came. He was sure of refining the Seven Turns True Pill. A few more.

Two hours later, Zhang Ye felt the fusion of the medicinal liquid, which had reached a certain point, and he snorted softly in his mouth: "True Dan turns!"

Zhang Ye cast the third change of the stars, subtly controlling the medicinal liquid. At the same time, he performed the Xuandan method and began to purify the liquid medicine for the first time. Purify the essence of the liquid medicine and remove the impurities of the elixir.

The so-called seven-turn true pill is to carry out seven fusions and purification of the true pill. After seven times of fusion and purification, the essence of the medicinal liquid can be completely fused together to produce the Seven Turns True Pill.

However, it is definitely not easy to complete these seven purification fusions. Seven times of fusion purification. Each time is more difficult than the last, as long as there is one mistake, the alchemy will fail, and there is no room for salvation at all.

"Z-"

Under the control of the third change of the stars, the liquid medicine eliminated the slightest impurity.

"Hum—"

Zhang Ye performed the Xuan Dan method, and a small tornado was born in the Dan furnace. The tornado swirled at high speed, devouring all the impurities. Ensure that there is no trace of impurities in the Dan furnace.

The cooperation of the three changes of the stars and the Xuandan method. It's perfect. Under the careful control of Zhang Ye, Zhang Ye completed the first fusion and purification. Successfully completed the Zhen Dan turn.

Time passed slowly, and two hours passed in a blink of an eye, and the sound of "Zizi" came out again in the Dan furnace, and the time for the second turn of the True Dan had arrived.

Zhang Ye continued to apply the third transformation of the stars, and cooperated with the Xuandan method to carefully carry out the second fusion purification. The second fusion and purification was twice as difficult as the first one, but fortunately, Zhang Ye had already prepared for this. Under Zhang Ye's careful control, Zhang Ye completed the second turn of Zhendan without any danger.

The process of alchemy is undoubtedly boring.

Although it was boring, Zhang Ye didn't dare to be distracted. He carefully controlled the fusion and purification, and worked closely with the fire spirit to successfully complete the third, fourth, and fifth turns.

At the time of the sixth turn of the True Dan, purification became extremely difficult. After five times of fusion and purification, the impurities in the liquid medicine have been almost removed, and the remaining impurities are very small and very active. If you want to get rid of these impurities, you can only rely on your keen spiritual sense to slowly distinguish the impurities from the essence, and then use the third change technique of the stars to remove them little by little.

At this time, the wonder of the third change of the stars is revealed. These extremely subtle impurities, if ordinary techniques are used, can not be eliminated at all. Only the extremely complicated technique of the third change of the stars can lock these subtle impurities and remove the impurities little by little.

"Huhuhuhu-"

Zhang Ye removed a little impurity from Zuihou, and eighteen hours had passed. Zhang Ye exhaled softly, only to feel tired, and his head began to ache faintly.

To refine the second-grade True Pill, you need to concentrate your energy all the time, lock the changes in the medicinal liquid with your spiritual sense all the time, and then remove the impurities little by little. These actions are very draining, and Rao is Zhang Ye's toughness, and he also feels unbearable.

"The sixth turn is already so difficult. The difficulty of the seventh turn is twice as great as that of the sixth turn, and it is very difficult to successfully complete the seventh turn and refine the elixir. At this time, Zhang Ye finally knew the difficulty of refining the second-grade true pill, and he no longer had a trace of certainty in his heart now.

Regardless of whether Zhang Ye was sure or not, four hours later, the seventh turn of Zhendan had finally arrived.

After six turns, the liquid medicine is already very pure. But with the fusion of the liquid medicine again, the impurities appeared again, and the chapter leaf needed to remove the impurities for the seventh time.

When the liquid medicine is fused, the essence of the liquid medicine will be formed, and various impurities will also appear. After the first six fusions, the impurities produced can also be quickly distinguished, and then the third transformation technique of the stars is used to throw all the impurities into the tornado.

But after this seventh fusion, the impurities appear very, very fine, even transparent crystals. These impurities are difficult to find and remove because they are small enough and the liquid is very dense enough to stick to them.

"Zizizi-"

Zhang Ye was shocked to find that although he continued to remove impurities, the seventh fusion of the liquid medicine still showed more and more impurities in the liquid medicine. This phenomenon is exactly what appears when alchemy fails.

"God, it's been so hard to get to this point, you must not fail!" Zhang Ye groaned in his heart, desperately casting the third change of the stars, frantically removing impurities.

Zhang Ye frantically eliminated impurities, but impurities still appeared in a steady stream, and the liquid medicine was fused with zuihou, although the impurities did not increase, but they did not decrease. If this situation continues, Zhang Ye's furnace elixir will definitely fail.

Zhang Ye's brows furrowed, and he quickly thought of a solution in his mind. After thinking about it for a while, a bold idea suddenly came to Zhang Ye's heart.

The amount of medicinal liquid in this Dan furnace is quite sufficient, and if everything goes well, four seven-turn true pills can be refined. Zhang Ye's idea is very simple, that is, directly discard half of the medicinal liquid and make every effort to purify the remaining medicinal liquid!

At this time, there are more and more impurities in the liquid medicine, and if you don't act again, the liquid medicine will become a waste pill. Zhang Ye's heart was ruthless, his mind moved slightly, and the medicinal liquid in the Dan furnace suddenly split into two halves, half continued to be purified, while the other half flew up and flew into the tornado.

This kind of alchemy is halfway through, and the practice of directly giving up half of the medicinal liquid can only be performed by Zhang Ye. Zhang Ye comprehended the method of spinning the pill, which could control the tornado in the Dan furnace, and easily devoured the abandoned medicinal liquid, without affecting the remaining medicinal liquid.

Another alchemist, even if it is an alchemy master like Gu Ding Zhenren, it is impossible to do this like Zhang Ye. They can only be honest alchemy, either refining a furnace of elixir or refining a furnace of waste pills.

Half of the liquid medicine was abandoned, and the purification speed of the chapter leaf was greatly accelerated. Under the crazy purification of the chapter leaves, the impurities in this half of the liquid medicine slowly decreased, and the liquid medicine became more and more pure.

At this time, Zhang Ye finally put his mind at ease, and a hint of joy appeared on his face. This pure medicinal liquid, if there is no accident, there is a great hope of refining the Seven Turns True Pill.

The liquid medicine became denser and denser, and the fragrance of the pill came out of the furnace. The fragrance is distant and fresh, and there is not the slightest impurity in it, which is exactly the sign of Cheng Dan.

"Zizizi-"

There was another strange noise in the Dan furnace. This abnormal sound was the sound that came out when the liquid medicine condensed into an elixir. With the condensation of the pill, the fragrance coming out of the pill furnace became more and more intense, and Gu Ding Zhenren and others, who were beaten unconscious by Zhang Ye, smelled the fragrance of the medicine, and their noses twitched slightly.

"Hahahaha, Harvest Dan!"

Zhang Ye felt that the pill had been completed, and couldn't help but let out a long laugh, and his hands changed slightly, turning into a recipe for collecting the pill.

"Whoosh-"

With the casting of the magic technique, the Dan furnace made a strange sound like a light dragon's groan, and two finger-sized golden pills, accompanied by a gray pill the size of an egg, flew out of the Dan furnace.

The rich aroma of the elixir, as if it was substance, filled the entire alchemy room.

Zhang Ye took out a jade bottle and put two golden pills into the jade bottle. The gray pill the size of an egg was the waste pill formed by the impurities and the half of the medicinal liquid, and Zhang Ye threw it away without looking at it.

Gu Ding Zhenren, Chang Qing Zhenren and Yu Dan Zhenren, who had been in a coma, smelled the rich fragrance of the pill and woke up. The three of them stared at the jade bottle in Zhang Ye's hand in disbelief, rubbed their eyes fiercely a few times, and shouted: "God! You have successfully refined! You have actually refined the second-grade true pill!"
