Han Feng naturally wouldn't sell these things, and he didn't urgently need spirit stones, unless it was a superb spirit stone, even if it was a top-grade spirit stone, it wouldn't be able to enter his magic eyes.

Han Feng calmed down, and then continued to open the furnace to refine the pill, one furnace after another, and time flowed like flowing water, and in a blink of an eye, more than ten years passed.

His Dan Dao power is getting stronger and stronger, although he has not yet reached the level of five flowers, but he feels closer and closer, just about to pierce a layer of window paper.

He suddenly stopped, silently practicing meditation in the sea of souls, and after a long while, he opened the furnace again to refine the elixir and improve efficiency.

Before I knew it, dozens of furnaces had passed, and that layer of window paper could never be pierced.

Han Feng frowned, he was thinking about his own methods, and checked again to see if he was going in the wrong direction. After careful inspection, there was no problem with his technique and direction.

"But why can't you break through?" Han Feng muttered to himself in his heart.

He also took out the Fu Danhua Lotus Law Book and studied it carefully, trying to understand something new from it.

According to this classic, the cultivation of soul power in the middle stage of the condensing bead is enough to reach the realm of five flowers, but at the moment of promotion, it will cause the heaven and earth thunder tribulation to come.

"Could it be that there is no Heaven and Earth Thunder Tribulation here?" Han Feng looked up at the sky, he was seriously thinking about the real reason.

He shook his head, put aside these distractions, and continued to refine the elixir in the furnace, trying to find out the core problem.

Time flashed, and another three years passed.

Han Feng urged the Dharma in his hand, and the four-flower pill in the Dan furnace suddenly spun around, and a lotus pattern slowly derived from its surface, but after a while, it disappeared in an instant, as if something was missing.

This situation has been repeated several times, and every time he is helpless, he really can't find a way to crack it, like this piece of heaven and earth can't support him to refine a five-flower level pill.

"It seems that we can only do it for the time being, and we can try it again when we go outside. Han Feng waved his hand to put away the Dan furnace, thought about it silently, and decided to seek a chance to break through after going out.

In fact, he is not long away from going out, and he only has thirteen years left.

He no longer cultivates, nor does he refine pills, nor does he draw talismans, but takes off and flies into the air, flying straight to the edge of this world, sitting and watching the expansion of heaven and earth, those flames and lightning seem to have an inexplicable rhythm, weaving heaven and earth, constantly expanding this world.

Such a spectacle is rare to see in 10,000 years, and the more Han Feng looks at it, the more he feels that he has benefited a lot, but he can't say it, and he can't express it.

Perhaps, when his realm reaches a higher level, he will be able to have some enlightenment.

The years passed in a long way, and another ten years passed in an instant.

Han Feng was still sitting quietly in this area, moving his position from time to time, following the pace of the expansion of heaven and earth.

Miraculously, in the past ten years, he had not cultivated at all, but his cultivation was steadily improving, even faster than his deliberate cultivation.

Moreover, the three forces in his body have all reached a balance, and all of them have entered the mid-stage peak state, touching their respective bottlenecks.

Han Feng did not leave, he still continued to observe the evolution of heaven and earth, and he was fascinated by it, he could be described as forgetting to sleep and eating, completely forgetting himself, and even he didn't know that his cultivation was improving.

He forgot the passage of time, immersed himself in the wonderful enlightenment, opened the door of his heart, and seemed to see a whole new world.

Time flies like an arrow, and more than three years have passed in the blink of an eye.

Han Feng suddenly looked up at the sky, a strange fluctuation flooded, and a mysterious power appeared around him, enveloping it in an instant, flashing lightly, and disappearing in an instant.

He felt a blackness, and when the light returned, he found that he was still staying at the edge of the lobby of the White Dragon Palace, as if he had never moved his body, and he was only a few feet away from the gate.

Han Feng glanced at the quiet lobby and found that there was nothing abnormal, so he immediately took out the Dan furnace from the storage ring and took out a large number of spiritual materials, all of which were of the twelve-grade level.

According to the Fu Dan Lotus Method, he put it in turn, combined with his previous perception, the magic formula in his hand changed continuously, and he continued to play out a mysterious multicolored seal formula, which was submerged in the Dan furnace.

After a while, the aroma seeped out of the Dan furnace, and it was extremely strong, much stronger than ever.

After another stick of incense, the Dan furnace shook slightly, and the moment Han Feng opened the lid of the furnace, the glow rose to the sky, fragrant and refreshing.

Han Feng's eyes flashed, he raised his hand to grab it, took out the pill from the air, fell into his hand, and observed it carefully, only to see that there were still no five complete lotus flowers on its surface.

However, in addition to the four lotus flowers with clear lines, there is also a bud-like pattern on the other side, which looks like it is budding and ready to be released, and it is obviously a little worse.

Han Feng pondered, he didn't expect such a situation to occur, which was really a little surprising.

He carefully reviewed it, thought about it for a long time, and slowly found out some problems from it, practiced in the sea of souls, and began to solve them one by one.

A day later, he opened the furnace to refine another elixir, methodically put in various spiritual materials, and manipulated the three-color flint to release a fierce flame, enveloping the Dan furnace.

But the final result was still unsuccessful, the fifth lotus flower still did not bloom, still in the bud state, but slightly more open than the previous one.

Han Feng naturally would not give up, took a deep breath, continued to study carefully, silently reviewed the drill, and looked for the true meaning.

Time flies, and before I know it, half a year has passed.

Han Feng forgot to sleep and eat, and went all out to refine the pill, he wanted to raise the power of his Dan Dao to the level of five flowers.

According to the introduction of the Fu Dan Lotus Transformation Method, only an alchemist who has entered the five-flower level can be called a master and can be regarded as a master.

Han Feng sighed leisurely, and could only calm down and continue to work hard to comprehend.

He made up his mind that he would not give up until he reached his goal, and he must advance his Dan Dao power to the Five Flowers Realm before leaving the White Dragon Palace.

This place can lead to the arrival of heaven and earth thunder tribulation, and can block all prying eyes, it is the most suitable place to break through, if he goes outside, he will definitely be exposed, once the Yu Immortal Sect knows that his Dan Dao cultivation has reached such a high level, he will definitely be accepted as his own use, and from then on he will be under their surveillance, and the blessings and disasters are unpredictable.

Time has passed, and more than a year has passed in the blink of an eye.

Han Feng refined one pill after another, and the fifth lotus flower of each one was still in the form of a bud, but it had gradually opened up, and it had progressed one after another.

On this day, he opened another furnace, when he opened the top cover of the Dan furnace, a large piece of lightning immediately appeared between heaven and earth, colorful, dense, the sky is vast, magnificent.
