Han Feng frowned, thought carefully, deduced repeatedly, recalled the previous four refining processes in his mind at high speed, compared and analyzed them one by one, trying to find clues from them.

Half a month later, his eyes were red, and he had already calculated various changes, but he couldn't grasp which plan was the best.

He can only continue to experiment now, if luck breaks out and he happens to hit the right one time, then he will be successful.

Han Feng refined Muyang Pill for the fifth time, and he still used the configuration scheme of the second time, but he fine-tuned the quantity of some spiritual materials, and according to his deduction, he tried to reach the most reasonable point.

In an instant, the medicinal liquid in the Dan furnace was suspended, all the impurities of the spiritual materials were eliminated, and the blazing light spread out, scorching and shining, and emitted a strong aroma, filling the entire secret room.

Han Feng's expression was solemn, he held the magic trick tightly in his hand, and the liquid medicine flowed, quickly building a lotus flower form, and the colorful brilliance overflowed, which was extremely gorgeous.

Han Feng stared at this medicinal lotus flower a little nervously, but after ten breaths, it did not collapse, and was steadily absorbing the energy of the three-color fire, and as time passed, the color became darker and darker.

After another ten breaths, he manipulated the lotus form to shrink inward, slowly condensing into a thumb-sized elixir, but there were no lotus lines on the surface, and the color was dull.

Han Feng held it in his hand, observed it carefully, and even released his soul power to probe into it, trying to crack its medicinal power structure and find out the flaws in it.

He pondered for a long time, but he couldn't find the method of building the medicinal power of this elixir.

It's right to think about it, after all, the medicinal power of this Nine Rank Pill is more majestic, and the condensation is more firm, after it is formed, it is not possible to decompose its construction method for a while and a half, if it is so simple, many high-grade pills will not be able to be refined.

Han Feng thought like this, and suddenly put this Muyang Pill in his mouth and swallowed it.

At the same time, he hurriedly looked inward and tracked the changes in this Muyang Pill.

He tried to use this Muyang Pill to release the rolling medicinal power in the process, and saw some clues, so as to obtain the mystery.

Han Feng's soul power poured out like a tide, firmly following the situation after this Muyang Pill entered his stomach.

Under the pressure of the Yuan Force in his body, this Muyang Pill burst rapidly, and a large amount of medicinal power gushed out, colorful and blazing, just like a volcanic eruption, and the scorching flames slammed out in all directions.

Han Feng's mind moved, and the Yuan Force in his body was mobilized, firmly imprisoning these medicinal powers, so that they would no longer spread.

His soul power followed closely, rushing into this mass of medicinal power, and carefully dissecting it.

He frowned, smiled, screamed, and his eyes lit up, but at last he reverted to a watery expression, as if he had encountered a difficult time.

I don't know how long it took, Han Feng's face became more and more solemn, as if something terrible had happened.

He suddenly opened his mouth and spewed out a cloud of air, which was the medicinal power of the Muyang Pill he had swallowed just now, but at this moment it had become black, like a poisonous mist.

Han Feng showed a palpitating expression, fortunately, he controlled it in time, if he really spread this pill all over his body, even with his physical body, he would have to suffer a lot of trauma.

Obviously, there is a big problem with this Muyang Pill, it is not a qualified pill, and it can even be said to be a poison.

Han Feng didn't find nothing, at least in this process, he had a detailed understanding of the changes in the medicinal power of this pill, which provided a good sample for his next refining.

Then, he pondered for half an hour, carefully reviewed the changes, and summed up a new spiritual material matching scheme.

Although he was not 100% sure, at least his heart was much more stable, and he immediately began the sixth refining.

Open the furnace, divide the fire, dosing the medicine, form a liquid, and turn the lotus.

These steps were completed in one go, and in less than a quarter of an hour, the liquid medicine once again turned into a lotus form, shining, shining, and beautiful.

This time, Han Feng held his breath and let this medicinal lotus flower spin dripping and spinning, absorbing the energy of the three-color fire to his heart's content, and the brilliance became more and more intense, dazzling.

After a full hundred breaths, Han Feng began to slowly control the lotus flower of the medicinal liquid to shrink inward, shrinking at a speed visible to the naked eye, gradually condensing into a pill, and lotus lines slowly appeared on the surface.

Han Feng was delighted to see it, but he didn't dare to relax the magic trick in his hand, and held it carefully, for fear that because of one of his mistakes, his previous efforts would be wasted.

In less than ten breaths, this pill was completely formed, the brilliance was all converged, and the Wuzi Dan furnace was spinning, and the dark incense flowed.

Han Feng was overjoyed, and with a twist of his wrist, his soul power dispersed, pulling this Muyang Pill out and landing it in his hand.

He looked carefully, and saw that this elixir was simple and unpretentious, and a lotus flower bloomed on the surface, but it was shining brightly.

He finally succeeded.

Han Feng knew that he was able to complete the refining of the Nine Rank Pill in such a short period of time, in fact, it was a matter of accumulation, and the twenty-seven years of work in that mysterious little world some time ago was not in vain, and it really laid a solid foundation for himself, and while achieving the Nine Rank Talisman, it also paved the way for this alchemy.

Especially this Fu Dan Lotus Method, it is obviously connected to the Dan Dao, and for Han Feng, it is really inappropriate.

He released his soul power to infiltrate it and swept it gently, only to see that it contained a golden light like an ocean, full of strong pure yuan medicinal power, which was definitely a great tonic.

Over the years, he hadn't obtained the Great Medicine Pill, but the Great Medicine Pill was really rare, and even if he had, it had already been consumed, otherwise he would not have forced him to refine the Pill himself.

Fortunately, the emperor lived up to his hard work, and finally let him successfully refine the Nine Rank Pill, such an achievement, even if he went to the big sect, he could hold an important position, comparable to an elder.

At least in the White Crocodile Valley, the Nine Rank Alchemist is still very rare, and he can be called a great pharmacist, but he is a top talent who is competing for it from all sides.

Han Feng calmed down his excitement a little, and after putting away this elixir, he immediately turned around and left this secret room, and walked to the right into the secret room in the middle.

He came to the book of alchemy vajra, picked it up, and read it again to make sure that nothing was left behind.

After three days and three nights, Han Feng sat down cross-legged, silently breathed for a while, and then took out the Muyang Pill, swallowed it directly, and swallowed it.

After this elixir entered his body, under the action of the rolling yuan force, it immediately dissolved, gushing out a fierce pure yuan medicinal power like a volcanic eruption, instantly filling his entire body, making him feel like he was in a sea of fire.
