Time is like an arrow, and time is like a shuttle.

Han Feng was in the mysterious world built into the remnant talisman, and he didn't know how time passed, and before he knew it, a full nine years had passed.

During this time, he devoted himself to the cultivation of the Five Elements Technique, and finally practiced the Five Elements Seal to the point of perfection, each seal was compressed to the size of two inches, as powerful as the sea, incomparably vast, sweeping nearly a hundred miles around, the void twisted violently, bent endlessly, and cracked countless times.

At the same time, he also found that the heaven and earth here are full of energy factors suitable for soul power cultivation, and through the cultivation of the ploughing soul technique, he has greatly improved his soul power cultivation, and he is infinitely approaching the middle stage of crystallization, but that bottleneck is also extremely difficult, no matter how much he uses various means, he can't break through, and it seems that there are still some necessary things missing.

He can only give up for the time being, silently condense the technique of the five elements, and shorten the casting time, otherwise no matter how strong the spell is, it will not be able to be put into actual combat, and it will not work at all, but will become a burden.

Just imagine, when confronting opponents of the same level, let alone ten breaths, the change between one breath is a hundred kinds of thousands of bells, and if you are not careful, you will fall into a situation from which you will never recover, how can you stop and cast spells slowly.

During this period, he also took the time to check the germination of spirit seeds everywhere, and found that the more high-level spirit seeds are, the more difficult it is to take root and sprout, and after nine years, the spirit seeds below the fourth grade have successfully taken root and germinated, and the spirit seeds at the fifth grade level have only taken root, but have not germinated, and the rest of the existences above the fifth grade have not moved, and they are still silently absorbing the spiritual power in the soil, slowly accumulating the power of the explosion.

"Hey, it seems that there is not much hope for this batch of spiritual materials, I really have to wait for them to grow up completely, I don't know what year and month!" Han Feng sighed and returned to the central area.

He released his soul power and infiltrated into the storage ring, and with a light sweep, he could see the spiritual materials inside.

I have to say that he has always been prepared, and he placed some spiritual materials to store in this storage ring very early, but the number is not much, after all, he did not expect that the remnant talisman would recover eighty-one branches so quickly, giving him the opportunity to enter this world again.

Fortunately, there are a complete range of these spiritual materials, which are enough to combine and refine the fifth and sixth grade elixirs.

Not only that, but he also stored the stoves and flame stones necessary for refining the elixir in advance, so that he could refine the elixir smoothly.

Of course, his Dan Furnace would not be a top-level existence, but it was not bad, reaching the top-grade level, refining the fifth or sixth grade of the pill was more than enough.

As for those flame stones, it can't be the grade of three-color fire, it's just red flame stone, the most common kind, just because three-color flame stone is hard to find, even if there are spirit stones, they may not be able to buy it.

Han Feng didn't waste any time, and immediately took out all kinds of spiritual materials, pill furnaces, and flame stones, and began refining the five-grade pill.

For the five-grade pill, he is at ease, and when he reaches the realm of three flowers like him, he will naturally not pursue the production rate, but needs to improve the refining level and strive to break through to the realm of four flowers as soon as possible.

Han Feng ran the Fu Dan Lotus Method, the technique was mysterious, and if he didn't have half a pillar of incense, he successfully refined a furnace of Wupin Pill, and there was only one grain in one furnace, which was one of the characteristics of the Fu Dan Hualien Method.

Another feature of it is naturally that the surface of the pill is painted with lotus runes, and this time the five-grade pill refined by Han Feng is only at the level of two flowers, and has not yet reached the level of three flowers.

"The Sanhua realm hasn't stabilized yet, it seems that we really have to continue to work hard!" Han Feng secretly sighed, and casually put this five-grade pill into a jade bottle and put it aside.

Han Feng was not discouraged at all, and continued to refine the five-grade pill, slowly entering the realm of complete selflessness, ignoring the outside world.

In fact, this world is silent, and he is the only one in the huge world, and it is impossible to disturb him at all.

Time flies, and half a month has passed in an instant.

Han Feng consumed all the spiritual materials in the storage ring and converted them all into fifth- and sixth-grade pills, but the level of refining pills still could not always be maintained in the three-flower realm, and among the ten furnace openings, about eight to nine times reached the three-flower level.

However, compared to the average alchemist, this success rate was already very high, enough to make them crazy.

Han Feng was still not satisfied, but because he had no spiritual materials, he was a good woman who could not cook without rice, so he could only give up temporarily, and after a short rest, he continued to practice the Five Elements Technique to shorten the spell casting time.

In fact, after his soul power increased, the casting time of the Five Elements Technique was also rapidly shortened, and a two-inch-sized black fire seal was completely cast, and it only took six breaths at this moment, but it still couldn't meet the requirements of actual combat.

Han Feng cultivated with his heart, and after a while, he completely settled down, not knowing the passage of time.

Soon, another nine years passed.

Han Feng raised his hand and pinched the trick, and played a trick on the ground, like a spirit, hovering and flying above his head, and a black fire mark appeared in mid-air in an instant, and this piece of heaven and earth suddenly burst into a violent sound, and a large area of spiritual energy gathered together, endlessly, like an ocean surging, rumbling, and like a monstrous flame, boiling and boiling.

Han Feng's soul light was wide in the center of his eyebrows, and the magic tricks in his hands changed continuously, gathering these spiritual qi and compressing this black fire seal, its speed was extremely fast, it reached two inches and two points in one breath, and after another breath, it reached the strongest two-inch state, solidified like a stone, the black light shone, and it was extremely dazzling.

Within a radius of 100 miles, the whole world was roaring, writhing, and spatial cracks appeared one after another, with infinite colored light and wind.

Han Feng didn't dare to really use it, he still carefully dispersed it, otherwise it would cause an uncontrollable situation, but it would cause a big disaster, although he believed that the world attached to the remnant talisman could not be so fragile, but he would not rush into danger.

Then, he took turns casting the Thick Earth Seal, Miao Water Mark, Xin Jin Seal, and Tianmu Seal, but the casting time was maintained at the level of two breaths, and he still couldn't reach the realm of instantaneousness.

"The technique of the five elements is really broad and profound, the deeper you dig, the more terrifying and fascinating it becomes!" Han Feng became more and more interested in this technique of the five elements, but he also felt that it was extremely difficult, and every step he improved consumed a lot of time and energy, that is, he had a mysterious world attached to the remnant talisman, which made him invisibly have so much more time, otherwise he would not want to cultivate this secret art in depth.

He rested for a while, and was about to continue thinking about how to make a further breakthrough, when he suddenly smelled a burst of aroma, which was light and light, and seemed to be extremely ethereal, but as a Nine Rank Great Medicine Master, he was naturally very clear about the qi of these elixirs.

"Well, it seems that those fourth-grade spiritual materials are ripe!" Han Feng nodded, showing a little joy, and hurriedly flew into the air and flew towards that area.
