Han Feng stretched out his hand and gently tapped the multicolored spar floor a few times, making a tinkling sound, which was extremely crisp.

As he sat here, he could feel that his thinking was much clearer, most of which was related to this multicolored spar floor, which had been improving his perception ability.

Han Feng guessed that he had been lying here to sleep before, and it was also because of the existence of the multicolored spar floor that he had entered a unique dream land and traveled in the major worlds in the chaos.

Although he hadn't learned anything in the major worlds, after waking up, he had really improved his soul cultivation, which made him feel sincerely happy.

He did so, lay down, and tried to sleep.

However, he closed his eyes, silently breathed, and tried for a long time, but he could not sleep, let alone fall asleep.

His whole person was refreshed, and there was still a little sleepiness, even if he deliberately hypnotized himself, he would be protected by his own soul body, so that he could not succeed.

Han Feng had no choice but to give up for the time being, and instead got up and sat cross-legged, continuing to study the Dan Fu Lotus Method.

His thoughts were extremely clear, his whimsical ideas kept coming, and the effect of his cultivation had greatly increased, which was obviously related to the improvement of his soul power.

Before you know it, another nine springs and autumns have passed.

Han Feng's Fu Dan Lotus Transformation Method has been practiced countless times in his mind, and various techniques have been deduced, and he believes that once he puts it into practice, it will inevitably improve greatly, and may be able to promote him to the realm of four flowers.

At the same time, his Five Elements Technique has also improved, not only has the casting time been further shortened, but the Black Fire Seal has finally broken through the compression of less than two inches, although it is only a trace, but the power is so great that it directly collapses the void into a small black hole, as if the space here cannot withstand its power.

Han Feng didn't dare to detonate it, dissipated this black fire mark as soon as possible, and then didn't dare to easily try to continue compressing it, after all, he couldn't control it yet, and if he was not careful, he would explode himself, and he would have to suffer.

He tried the other four seals, and they all managed to compress a little, and the pressure was like a sea, which made people's hearts palpitate.

The fly in the ointment is that this compression of the silk requires three breaths of his work, and it is not suitable for actual combat.

After nine years of hard cultivation, Han Feng found that he was still not tired at all, and he couldn't force himself to fall asleep, so he silently got up and flew towards the area where the spiritual materials were planted.

He inspected and found that all the spiritual materials were fully mature, and they were old enough to be put into use.

His eyes were full of joy, and he pocketed most of these spiritual materials, and a small number of them were replanted as spiritual seeds, presumably after a while, there would be a large number of spiritual materials to mature.

Han Feng returned to the central position, sat down, took out all the utensils needed for alchemy, and began to refine the four-rank pill Long Yuan Dan, he decided to start with the simple four-rank pill, gradually advance, and continue to accumulate experience.

For the refining of Long Yuan Dan, he has long been perfect, and he can issue a furnace every half an hour, and each pill has reached the realm of three flowers, with incomparable fragrance and strong medicinal power.

After two or three spring and autumn seasons, he had exhausted all the fourth-grade spiritual materials, and two large piles of Dragon Yuan Dan had accumulated on both sides of him, exuding a scorching brilliance and brilliance.

Han Feng showed a slightly tired look, glanced left and right at the two large piles of Long Yuan Pills, and sighed secretly in his heart, obviously not reaching the state of the four flowers he wanted, although these four rank pills were all in the form of three flowers.

"The realm of the four flowers is really much more difficult than imagined!" Han Feng muttered to himself, but he was not discouraged in the slightest, and after a short rest, he threw himself into the refining of the five-grade pill again, completely unaware of the passage of time.

He selflessly refined the five-grade pill, and soon another three or four years passed.

During this period, every time he refined a furnace, he had to stop, spend a long time pondering it repeatedly, trying to find out some mysteries from it, so that he could get a glimpse of the door to the realm of the four flowers.

But when he used up all the five-grade spiritual materials, he still stayed in the Sanhua realm, as if he was some kind of confinement, locking his refining level.

He thought about it for a long time, but he couldn't figure it out, and he stopped refining the six-pin pill for the time being.

He put all the pills that had been successfully refined into the storage ring, and at the same time immersed himself in his mind, silently studying the Dan Runic Lotus Method.

In the blink of an eye, another three winters and summers have passed.

Han Feng forgot to sleep and eat, and devoted himself to the cultivation of the Dan Fu Lotus Method, racking his brains to think about countermeasures to crack the Four Flowers Realm.

Of course, during this period, he would occasionally open the furnace and try to think of the methods he came up with, but they all failed one by one, not only did he not become a Dan, but he almost blew up the furnace, and the muffled sound continued.

After repeated failures, he finally realized a method, that is, to put the five-rank pill Bixia Pill into the Dan furnace to re-refine, plus a few six-grade spiritual materials, he tried to reorganize the medicinal power structure of the five-grade pill, maybe he could get some inspiration from it.

He thought of it, and immediately took out a pill of Bixia Pill and put it into the Dan furnace, and carefully manipulated the firepower to remelt the finished Sanhua Bixia Pill into liquid, emitting a brilliant green light.

Immediately after, he quickly put in four kinds of six-grade spiritual materials, differentiated the firepower, dissolved them instantly, and fused with the turquoise solution, reacted violently with each other, and burst into a more blazing light, and after a while, there was a sudden bang, and the furnace lid flew up, and cracks appeared in the entire Dan furnace in an instant, bursting violently, scattering thousands of qi waves, sweeping Zhou Tian.

When Han Feng saw that something was wrong, he dodged away as soon as possible, and stayed away in an instant, not being affected by the center of the explosion, and the scattered waves of qi were all resisted by the colorful light emitted by his soul body, and they were not injured at all.

It took a while for the aftermath of the explosion to dissipate and the world to be quiet again.

Han Feng flew back, and while thinking about it, he cast a spell to put away the fragments of those Dan furnaces, and pondered it carefully, but he couldn't see any clues from them.

"It seems that the idea is wrong, and the prescription cannot be changed at will. Han Feng thought, and then muttered to himself: "However, it is feasible to recreate the refined elixir, and if you study it deeply, you may be able to understand a lot of things!"

He immediately changed to another brand-new Dan furnace, took out the flame stone and a Bixia Pill, put the pill into the furnace, pinched and urged the flame stone, let it release a scorching flame, and soon let the Bixia Pill in the furnace dissolve into a turquoise liquid, which was brilliant and brilliant.

He carefully controlled the firepower, carefully observing the changes in the medicinal power of this solution, and faintly, there were faint runes on the surface of the solution, like a broken lotus flower pattern.

In a moment, the aroma emitted by this turquoise solution suddenly became stronger, and the color became darker, and it seemed that there was a new change.
