As he observed, the crack on the lotus flower of the potion became bigger and bigger, and after a while, one of the petals fell off and turned into the liquid again, and it was slowly turning black.

At the same time, as if implicated, as this petal fell off, another petal also withered rapidly, and it fell off again in two breaths.

This medicinal lotus flower only has four petals, and when two pieces are dropped, it will naturally not be formed, and then the entire lotus flower will collapse and dissipate, turning into a pool of blackened medicinal liquid.

Han Feng withdrew his soul power and let those medicinal liquids be burned by the three-color fire in the end, ignoring them.

There was a slight look of enlightenment on his face, and he found that there was something wrong with his control of the three-color fire, in short, he didn't have the right time.

The three-color fire is indeed very different from the earth fire he used to boil the rune paper in the past, it is more powerful and more flexible, if it reaches the realm of fire control that is wonderful to the peak, the effect of the three-color fire is naturally far better than that of ordinary earth fire, but if it is the work of half a bucket of water, it will be more than worth the loss, but it will be self-defeating.

Han Feng carefully reviewed it, and silently studied the Fu Dan Lotus Method in his mind, looking for his own shortcomings, and repeatedly thinking about how to solve it.

By the time he figured it out, three hours had passed.

Han Feng didn't feel the slightest bit anxious, but became excited, and returned to the state of drawing talismans back then, such a drunken feeling!

His eyes were blazing, and he once again took out a spiritual material for refining the Dragon Yuan Dan, but this time he had doubled the amount of Fire Cloud Grass to absorb the excess heat of the three-color fire.

Fire, dosing, boiling, alchemy!

The whole process was like a cloud of water flowing with peers, without the slightest hindrance, and soon it reached the step of liquefiing the lotus, and Han Feng carefully controlled the output of the three-color fire.

Sure enough, due to the addition of Fire Cloud Grass, the heat of the three-color fire was distributed, and there were no more abnormal cracks.

The lotus flower of the medicinal liquid is lifelike, slightly rotated, and under the backdrop of the three-color fire, it is extremely beautiful.

When it absorbs enough energy, it begins to slowly condense, like a flower blooming and bearing fruit, and gradually gives birth to an elixir.

After another thirty breaths, this Dragon Yuan Dan was finally born.

Han Feng sniffed it carefully, and found that there was no aroma escaping, he chuckled in his heart, and thought that he had failed again, but after pulling this pill out, it really surprised him, it turned out that all the medicinal power was restrained into the pill, and it was not wasted at all, and a lotus flower pattern was condensed on its surface, shining and beautiful.

It finally happened, and it worked much better than he had imagined.

He tried it himself, and after a little evaluation, he knew that the medicinal effect of this Dragon Yuan Pill was more than ten times higher than that provided by the Three Leaf Gates.

If it was evaluated according to the level of the effectiveness of the existing elixir, the elixir he refined could be regarded as a local product.

He had just come into contact with the way of alchemy, and he had such an achievement, if he let those alchemists in the outside world know, he would have to drop a lot of jaws.

Han Feng didn't think it was a big deal, after all, he was a nine-grade talisman master, and it was not difficult to refine the four-grade elixir under the bypass.

In the following time, he pondered for a while, reflecting on the advantages and disadvantages of his refining process this time, which can be described as excellence, so that his skills could be improved again.

He then refined several furnaces of the Dragon Yuan Pill, each furnace only had one pill, and each time it was extremely successful, even one furnace was better than the other, and the effectiveness of the pill was also significantly improved.

This is also the special feature of the Fu Dan Lotus Method, unlike other methods, which can produce several or even more than ten pills in one furnace.

After Han Feng felt that his alchemy level was completely stable, he began to refine the five-grade pill.

Like the talisman, the fifth-grade pill is a big level higher than the fourth-grade pill, and the difficulty will naturally be many times higher.

Han Feng studied carefully for several days, and also opened the furnace to refine it several times, but all of them ended in failure, which made him feel that alchemy was not so easy.

Naturally, he wouldn't give up, anyway, he still had a large amount of spiritual materials in his storage ring, which were all obtained from other opponents, which was enough for him to squander for a long time.

What's more, there is also a medicine garden outside, and most of the elixirs that replenish vitality are available, so there is no need to worry about the supply of spiritual materials.

The five-grade pill that Han Feng refined this time was called Bixia Dan, which was an elixir that could greatly replenish vitality, and once it was refined, it would also have some effect on his body at the moment, many times stronger than the Dragon Yuan Dan.

In fact, all the pills in the Fu Dan Lotus Transformation Method are pills for refining the Yuan and Qi Enhancement, as if they are for the purpose of cultivating the Soul Alchemy Vajra Technique.

The problem he is encountering now is still the mastery of the fire, he is carefully studying the output of the firepower and the combination of the three colors of fire, not the energy of each color of fire is the same, how to distribute it has become the key to solving the problem.

He studied hard, and finally after thirteen failures, he thoroughly mastered the method of flame color separation, and was able to flexibly control the heat output of the three-color fire, reasonably allocate the energy distribution of various colors of flames, so that the medicinal power of various spiritual materials was just right to fuse together, and finally successfully completed the refining of Bixia Dan in the fourteenth refining.

Han Feng was secretly happy in his heart, and took out the Bixia Pill from the furnace, and suddenly the blue light shone brightly, and the agility was extraordinary.

He felt its extremely rich medicinal power, looked at the lotus flower on its surface, and felt a little excited in his heart, so he immediately picked it up, put it in his mouth, and swallowed it in his stomach after a few clicks.

A thick warm current rose from his stomach and quickly spread throughout his body, making Han Feng feel comfortable, this pill was comparable to a hundred Dragon Yuan Pills bursting out at the same time, making his physical body change.

However, it was only that this grade of elixir was far from being able to break through the bottleneck, and he still had to continue to study and refine a higher-grade elixir before it was possible.

Han Feng took a short break and continued to refine the Bixia Pill, and after thoroughly mastering the refining method of the Five-Rank Pill, he set his sights on the Six-Rank Pill Formula.

In terms of the method of Fu Dan Lotus Transformation, the six pins of Dan Fang that he remembered were very clear, and it was not difficult for Han Feng to master, but he had only practiced it twenty or thirty times, and he had not succeeded once.

He felt a little frustrated, repeatedly deduced, and solved various problems one by one, but he couldn't completely eliminate them, and in the end, he used the soul power cultivation of the crystal realm to pinch out a six-grade pill, and the lotus lines on its surface were all incomplete, and the medicinal power was naturally greatly reduced, and it was just a step stronger than Bixia Dan.

Obviously, this is a semi-finished product.

But Han Feng didn't see it that way, holding this semi-finished product named Chiri Dan and looking left and right, his eyes were shining, constantly analyzing the combinations, checking and filling in the gaps.
