In a moment, Han Feng went to the nearest area where the four-grade spiritual materials were planted.

He looked down in the air at a height of nearly 1,000 zhang, and saw that the spiritual soil within a radius of dozens of miles was overgrown with all kinds of spiritual materials, flowering and bearing fruit, and spitting fragrant fragrance.

Han Feng was overjoyed, and immediately swooped down, came to the edge of the spiritual land, and began to pick these spiritual materials.

His soul power dispersed, walked all the way in, and began to harvest the spirit flowers and spirit fruits all over the ground in the air, and in less than half a pillar of incense, he pocketed all the spiritual materials in this area.

Then, Han Feng went to another four-grade medicine garden, which was also full of fragrance, and all kinds of spiritual materials were ripe, which made him overjoyed.

In less than half an hour, he harvested ten medicine gardens in a row, which were full of four-grade spiritual materials. Of course, he left some of it as a spirit seed, and he could continue to plant it in the future.

When he went to the medicine garden where the five-grade spiritual materials were planted, he found that the spiritual materials there were also growing well, and it must not take long to mature.

This was unexpected, he didn't expect such a harvest in just eighteen years, which surprised him.

Generally speaking, even if it is a fourth-grade level spiritual material, if it is cultivated in the outside world, it often takes a jiazi of time to mature, but it only takes eighteen years here, which shows the fertility of the soil and the richness of the spiritual energy here.

Han Feng calmed down, calmed down a little, and went to look at the Sixth Grade Medicine Garden and the Seventh Grade Medicine Garden again, and found that those two spiritual materials had just taken root and sprouted, and the buds were like jade, shining, and emitting all kinds of light.

As for the spirit seed of the eighth grade, it has not moved at all, and it is obvious that it has not yet accumulated enough energy to break through the ground for the time being. He only has spirit seeds below the eighth grade, and the spirit seeds of the ninth rank or even above the ninth rank can be found in the wild, and they are generally strictly controlled by the main vein sect, and it is difficult for the branch vein sect to obtain.

In the early years, when Han Feng was in the White Crocodile Valley, he had entrusted Di Di to purchase, but he spent a lot of energy and only bought spirit seeds below the eighth grade, even if he used Lin Xiaoyue's relationship with Ge Sheng, he could not successfully find the spirit seeds above the ninth grade, obviously this is an extremely important material, and the main vein sect is strictly controlled.

Han Feng felt a little regretful in his heart, turned around and left this area, returned to the central position again, sat cross-legged on the multicolored spar, silently breathed, and then began to practice the Five Elements Technique again.

According to his previous cultivation plan, he must first raise this technique to the point where he can perform it as he wants, so that he can effectively exert the true combat power of the Crystal Transformation Realm.

After a while, Han Feng completely settled down, closed all his senses, and devoted himself to this cultivation, unaware of the passage of time.

Time passed like water, flowing quietly, like a dream, nearly nine years passed rapidly. So far, Han Feng has spent twenty-seven years in this mysterious world.

On this day, Han Feng opened his eyes, and as soon as his thoughts moved, a black fire mark appeared above his head, which was compressed to the size of two inches in an instant, completely reaching the realm of instantaneousness, as long as he wanted to launch it, his mind could launch an attack together.

However, he naturally wouldn't activate it, and with a twist of the spell in his hand, this black fire mark slowly converged and gradually collapsed.

He was happy in his heart, and finally the emperor lived up to his hard work and successfully achieved the set goal.

Next, Han Feng spent another three years successfully connecting the Five Elements Technique into a ring of the Five Elements, with colorful light shining, among which there were five shining two-inch beads floating, and the power released was monstrous, covering a radius of hundreds of miles, and the void cracked into thousands of gaps, the colored light shone brightly, and the energy boiled, making Han Feng feel terrified.

Han Feng didn't dare to move, and carefully dismantled this ring of the Five Elements, lest it explode and cause huge damage to this piece of heaven and earth.

After more than ten breaths, the ring of the five elements above Han Feng's head completely dissipated, turned into rolling energy, and returned to heaven and earth.

Han Feng secretly breathed a sigh of relief, then got up, flew to the area where the spiritual materials were planted, checked the growth of the spiritual materials, and found that the fifth-grade spiritual materials were completely mature and ready for picking, and the sixth- and seventh-grade spiritual materials also grew buds, and they would soon bloom and bear fruit, and even the eighth-grade spiritual materials would also sprout, which made him happy.

Han Feng quickly picked most of the fifth-grade spirit materials, leaving a small amount as the spirit seeds.

He turned around and left, but returned to the central position, took out the Dan furnace and the flame stone, and at the same time took out all kinds of four-grade spiritual materials, and threw them into the Dan furnace step by step, urging the flame stone to release fire power to scorch the Dan furnace, and then run the Dan Fu Lotus Method to refine the four-grade pill.

In a moment, the four pins of the pill in this furnace were successfully completed, naturally there was only one grain, and its surface was painted with three lotus runes, and the rune light danced with Danmang, and the medicinal fragrance was fragrant.

Han Feng put it into another jade bottle and continued to refine it.

Unconsciously, half a year had passed, and Han Feng had exhausted all the fourth-grade and fifth-grade spiritual materials he had picked, and all of them had been converted into fourth- and fifth-grade elixirs, totaling six or seven thousand, and even the jade bottles he had prepared were not enough, so they could only be placed in a certain area of the storage ring at will.

Most of these pills are in the state of three flowers, only a very few are at the level of two flowers, although they still have not completely reached the realm of three flowers, but they have basically stabilized, especially when refining the four pills, he can refine 100% of the pills at the level of three flowers.

Han Feng knew that he still lacked a lot of practice, but now that all the spiritual materials had been used up, and the sixth and seventh grade spiritual materials were not yet mature, he had to pause and instead practice the drawing of the tenth-grade rune.

Here, his comprehension ability will be greatly improved, so he doesn't want to waste any time and cultivate with his heart.

He had already been able to skillfully draw the nine-grade rune before, in fact, his level had basically reached the level of the ten-grade rune master, but he lacked the training to draw the ten-grade rune, and he was in a hurry some time ago, and he had no time to spare to practice.

Han Feng immediately began to comprehend the Myriad Fu Secret Book that he had received from the Ten Thousand Scripture Pavilion of the Moyun Sect earlier, and the jade slip of this classic had already been refined by him and was firmly remembered in his mind.

Fortunately, he prepared in advance, otherwise when he came here, there would be no ten-grade talisman for him to comprehend, so he could only catch blind.

Han Feng soon entered a state of deep contemplation again, completely forgetting about the outside world, letting time pass, I don't know how long it took, he slowly opened his eyes, there seemed to be a bit of enlightenment in his eyes, and immediately began to draw the ten-rank talisman.

He used aura as ink and soul power as a pen, swaying wantonly, and after a while, a half-finished product of a talisman appeared in mid-air, and the talisman was shining brightly.

Han Feng gradually discovered that the overall rune structure of the ten-grade rune was similar to that of the nine-grade rune, and the first half was not at all difficult for him, but after passing through thousands of mountains and rivers, when he went to the central region, he suddenly encountered an abyss, and the fog was heavy, and he couldn't see the other side clearly.
