Han Feng wanted to put away this book, but found that he couldn't put it in the storage ring, and was blocked several times by the pale cyan light emitted by this book.

In fact, the same was true of the Alchemy Vajra Recipe Text, which emitted a brilliant pale yellow light that prevented him from doing so.

He had to give up and put them all back on the stone table.

Fortunately, his soul power cultivation has crystallized, and no matter how obscure the content is, it can be forcibly remembered and stored in the soul sea, so that it will not be forgotten or lost.

Han Feng turned around and left this secret room, and after a while, he crossed the arch on the right and entered the last secret room.

It is indeed an alchemy room, with complete facilities, earth fire, Dan furnace, etc., and there is no vacancy.

Han Feng knew that time was precious, and he was not much left from the end of this secret realm trial, so he walked to the edge of the Dan furnace, pinched his fingers, and shot out a magic trick, opening the ground cover, and guiding the earth fire into the furnace.

The earth fire was a three-color fire, red, orange and yellow, blazing incomparably, even Han Feng's physical body, he could feel the heat rolling in through the Dan furnace, which surprised him.

Although he is only a beginner, he is also a great talisman master, and he still knows a little bit about three-color fire. In fact, when he was boiling rune paper in the Shamrock Gate before, he knew something.

It's just that the fire he used to boil the rune paper back then was only a single-color fire, the lowest-level flame, and the three-color fire was much more advanced, and it needed to be found in a special leyline location, and it was generally hard to find.

Legend has it that there are seven colors of fire in this world, which is the strange fire of heaven and earth, which can be directly used for cultivation, and is the best tonic for fire-based exercises, and no one has ever received it.

"It's clear that those who come in here are going to learn alchemy, everything is ready!" Han Feng muttered in a low voice while familiarizing himself with the ground fire.

After more than half an hour, Han Feng had completely mastered the control of the flames, which could be regarded as the first step in completing the alchemy.

This is also required by the Fu Dan Lotus Method, the alchemist must have enough understanding of fire, otherwise how to manipulate the flame to remove the impurities of the elixir and refine it into a pill.

Han Feng lightly exhaled a breath of turbidity, raised his hand and waved, and took out more than ten elixirs, with different colors and varieties, which were the materials for refining Long Yuan Dan.

He had to start practicing with the four pins of pills, first increase the success rate, and then gradually improve his alchemy skills, refining the pills he wanted step by step.

In his early years, he had taken a lot of Murong Can's Long Yuan Dan, but he didn't expect that after many years, he would refine it by himself, but it could be regarded as a creation to make people, the world was uncertain, and it was impossible to speculate.

The magic trick in his hand flew over, controlling the output of the earth fire, and every once in a while, he pointed to a spiritual material and flew into the Dan furnace, so that they were thrown into the three-color fire in an orderly manner.

Soon, all the spiritual materials turned into a liquid colloid, and under the traction of Han Feng's technique, they were suspended above the flames, rising and falling, constantly merging, all kinds of gases were emerging, the colors were mixed, and the smells were also varied.

Han Feng had experience in boiling rune paper, and after such a series of operations, he immediately regained the feeling of the past, and secretly thought that the talisman and alchemy were originally one family.

Especially when boiling these spiritual materials, removing impurities and purifying medicinal power, he became more and more handy, not like a beginner, but like a master, skillful.

Even, he had a whim, and some of the techniques in the drawing talisman were also applied to the refining of the elixir, and the effect was wonderful, and the efficiency was improved a lot, and the impurities between the various spiritual materials were quickly removed, and after a while, they became extremely transparent and fused with each other.

This is also the law of Fu Danhua Lotus Law is not limited to the law, the Tao law is natural, and it reaches the highest realm, and you can do whatever you want, and you can come at your fingertips.

In other words, in the process of refining the elixir, any method can be used, as long as it is a method that can improve the efficiency of alchemy.

Of course, at this stage, Han Feng could only follow the basic rules, sort out the energy differences between the spiritual materials, and try to make them better integrated.

Next, he transformed into the Fu Dan Lotus Method, crossed his hands, and conjured a lotus-like seal, and smashed into the Dan furnace, so that the spiritual materials that had melted into juice completely melted together, and also turned into a lotus-like existence, in the three-color fire, dripping and swirling, revealing a pungent fragrance.

It's just that this lotus flower only lasted for three breaths before it began to crack, and it seemed to be about to disintegrate.

Han Feng frowned slightly, raised his hand to grasp the magic trick, and his soul power rolled out, forcibly re-consolidating the medicinal liquid lotus flower in the Dan furnace with the cultivation of the Crystal Transformation Realm, making up for the cracks, and then slowly condensed it into a single pill according to the method of alchemy, and there was also a lotus pattern engraved on it.

Dancheng!

The fragrance is incomparable.

Han Feng turned his technique, let the earth fire retreat, closed the ground cover, and then the soul power moved slightly, dragging this Dragon Yuan Pill out and falling into his hands.

He looked at it carefully, and still found that there was a gap on this elixir, although it was so small that it was imperceptible, but it really existed.

However, this pill is indeed completed, but it is still several levels away from the quality that Fu Danhua Lotus Method wants to pursue, and it can even be said that it is really necessary to strictly follow its standards, this pill is a waste pill.

Han Feng took out a Dragon Yuan Pill brought from the Sanye Gate, compared the two, and carefully analyzed it, the Dragon Yuan Dan he had just refined was not inferior to the Sanye Gate refining in terms of quality.

He didn't hesitate much, he simply put the elixir he had refined into his mouth, chewed it, and immediately a stream of heat flowed into his body, although for his current physical body, this supplement was almost the same as non-existent, but he could indeed feel the existence of the medicinal power.

This shows that the pill he refined can still be taken.

Han Feng was not satisfied, secretly guessed, and muttered, "Could it be that I temporarily added the talisman technique just now, which led to the existence of this crack?"

He didn't understand it, so he simply took out more than a dozen spiritual materials, all of which were materials for refining Long Yuan Dan, and put them into the Dan furnace one by one.

This time, he completely operated in accordance with the Fu Dan Lotus Transformation Method, and every step was meticulous, doing his best to do a perfect job.

Indeed, after this process, he did not make the slightest mistake, but at the closing stage, there was still a crack in the lotus flower, which made his face full of disbelief.

He calmed down, and did not rush to use his powerful soul power to forcibly tighten this medicinal lotus flower, but dispersed his soul power and carefully observed the changes of this lotus flower, to see how its cracks were derived, where it would go, and what results would it lead to in the end.
