Han Feng knew that the situation was not good, so without saying a word, the magic trick in his hand changed, and he manipulated this mass of solution to turn into a lotus flower, and it was obvious that he was trying to refine it into a pill again.

But this lotus flower only lasted for three breaths, and then it suddenly collapsed, and after a while, thick smoke appeared, spontaneously combusted, and turned into ashes.

Han Feng hurriedly opened the lid of the furnace, cast a spell to disperse the smoke, clean up the slag, and then fell into deep thought, silently reviewing everything that had just happened.

After thinking about it, he gradually sorted out some clues, but he was still uncertain and still needed to be verified repeatedly.

Han Feng took out another Bixia Pill and threw it into the Dan furnace, the flame stone was suspended below, and after he played a spell, bursts of flames immediately rose, extremely red, and as beautiful as the sun.

The Bixia Pill in the Dan furnace melted into a solution again after a while, and the turquoise light spread out, and the runes flickered.

Han Feng's soul power dispersed, observing it wholeheartedly, and carefully deducing the veins in it.

But the solution lasted too short, and in just five breaths, its light began to dim, and the runes became less clear.

Han Feng raised his eyebrows, and cast a spell to strengthen the fire output of the flame stone, making the solution light up again, and the runes were also revealed more clearly, allowing him to see clearly.

However, the process was extremely short-lived, and the mass of solution dimmed again, almost instantaneously, and began to turn black, and smoke began to rise.

Han Feng's reinforcing the flame stone's firepower output again was to no avail, unable to restore it to its original state, but instead accelerated its annihilation, turning it into a handful of charcoal in the blink of an eye.

His eyes flickered, he fell into deep thought, and then after cleaning up the Dan furnace, he concocted the same method, and continued to take out the Bixia Dan and return to the furnace to rebuild, trying to get some inspiration from it.

......

As time passed, the Bixia Pill in his storage ring was rapidly consumed, and after a few months, he melted nearly a thousand pieces, if it was known by people from the outside world, he would be shocked, and he would definitely scold him for destroying the heavens.

It must be known that each Bixia Pill in the state of three flowers is worth a lot, nearly a thousand, so how many spirit stones do you need to spend to procure.

Han Feng naturally didn't care about these pills, anyway, the alchemy technique had improved, and he didn't have to worry about not having spirit stones in his account.

In fact, with his current strength, many of the things he needed could not be purchased by spirit stones, and no amount of spirit stones could make him go further.

After so much practice, he had a clearer understanding of the medicinal structure of Bixia Dan, and he seemed to have some understanding.

He stopped, flew straight to the spiritual material cultivation area, checked the growth of the five-grade spiritual materials, and found that they were not yet fully mature, but they were not far away, and I believe that they could be harvested in less than three years.

Han Feng could only turn back to the central position, and did not continue to take out the Bixia Pill and rebuild it, but took out a large handful of six-grade spiritual materials, all kinds, fragrant, and put them into the Dan furnace in turn, raised his hand to play a trick, urged the flame stone, controlled the fire, and refined the six-grade pill Chiri Dan.

The difference is that this time he refined the Chiri Pill, the amount of spiritual materials put into it was much more, more than twice as much as before, and after all the spiritual materials were melted, they turned into a large ball of spiritual liquid, suspended in the Dan furnace.

Han Feng pinched his hands and increased the fire output of the flame stone, causing this ball of spiritual liquid to surge, a large amount of green smoke came out, and the impurities quickly disappeared, making it more pure.

Then, he divided his hands, and the mass of spiritual fluid suddenly split into two, turning into two small balls of spiritual liquid, each dripping and circling.

The magic formula in his hand suddenly changed, and he began to run the Fu Dan Lotus Method, allowing the two groups of spiritual liquid to slowly condense into a lotus state, spinning endlessly.

Han Feng was cautious, and with the ten fingers of both hands moving together, he shot out a series of azure seals, quickly submerged into these two clouds of spiritual fluid, and forced out bursts of green smoke again, allowing more impurities to be cleared out, making the light they emitted even brighter.

It didn't take long for these two balls of spiritual fluid to begin to shrink, gradually compressing inward into the form of a pill, but it was still the size of a fist, and it was still far from becoming a pill in the end!

Han Feng's two hands suddenly closed again, and the two lotus-like spiritual fluids fused together, turning into a dazzling liquid lotus flower, shining radiantly and dazzling.

Slowly, a series of runes appeared on the lotus flower, and the momentum swelled, and the halo expanded, reflecting the entire Dan furnace, making the furnace walls extremely transparent.

However, at this moment, this liquid lotus flower suddenly cracked, and cracks emerged without warning, collapsing, completely dispersing, and turning into a mass again, even with those runes.

Han Feng was secretly anxious in his heart, and the seal in his hand flew over, and he shot out one magic trick after another and submerged into it, trying to stabilize this spiritual liquid.

But he still couldn't contain the change in the spiritual fluid, and puffs of black smoke flew out uncontrollably, and finally disappeared completely, leaving only a small residue behind.

Han Feng sighed helplessly, he comprehended the method just now in the previous Bixia Pill recreation, and tried to separate two parts of the spiritual liquid to fuse in order to increase the medicinal power, but he didn't expect that he couldn't fuse, and he collapsed directly.

"What went wrong?" Han Feng muttered to himself after cleaning up, his brows furrowed.

He reviewed it several times, but he couldn't come up with a reason.

Han Feng tried again, but the result was still the same, there was no progress, it seemed that his method was wrong again.

He was not reconciled, and tried several times, but to no avail, so he had to give up temporarily.

"Isn't it also a modification of the prescription to increase the dosage of medicine?" he pondered in his heart.

"I don't believe it, it's definitely something I haven't understood!" Han Feng thought again.

He reviewed all the previous practices, sorted them out from beginning to end, silently pondered the key points, and gradually realized a method.

He immediately took out all kinds of six-grade spiritual materials, but the amount was just the amount of one Cheng Dan, and after being put into the Dan furnace in turn, under the fire of the flame stone, all of them melted into spiritual liquid, completely fused together, bursts of green smoke came out, and under his various techniques, it gradually condensed into a lotus flower, and it completely turned into a Red Sun Pill in a moment.

Han Feng didn't take it out, but suddenly increased the firepower, letting it melt into spiritual liquid again, and then he immediately took out a large handful of six-grade spiritual materials and threw them into the Dan furnace, turning into a large piece of spiritual liquid and combining with it, emitting bursts of green smoke.

In a short time, the old and new spiritual fluids were completely fused into one, slowly turning into a lotus flower, and the turquoise light was extremely blazing.

Han Feng slowly ran the spell, so that this lotus flower slowly condensed into runes, inlaid on the petals, shining and dazzling.
