Han Feng continued to practice, making the Xuan Soul Sword stronger and stronger, and gradually, its light was restrained, like a sword hidden in the edge, if it didn't move, it was earth-shattering.

For the next ten years, he devoted himself to studying the parchment scroll and improving the power of various spells, such as the Xuan Soul Needle, the Xuan Soul Sword, the Soul Power Flame Transformation Method, and the Five Elements Technique.

Although his Five Elements Technique could not be compressed, the cast time of the Ring of the Five Elements was further shortened, half a breath faster than before, allowing his combat power to further increase.

During this period, he had been to the planting area of the eight-grade spiritual materials, but found that the eight-grade spiritual materials were still not ripe, but the four-grade spiritual materials planted later were mature, but Han Feng did not rush to pick them, but let them continue to grow, boil them for some years, and wait for later use.

In addition, those six or seven grade spiritual materials left behind were also picked by him and replanted as spiritual materials, the land was extremely fertile, and he didn't need to manage it, they could grow on their own, saving him a lot of effort.

Before I knew it, another three years had passed.

Han Feng slowly found that his cultivation could no longer be improved, unless he returned to his physical body and turned to practice the art of refining the body and the method of practicing qi.

"By the way, I don't know if the soul body can practice the Spirit Refining Vajra Technique and the Yao Sun Heavenly Technique?" Han Feng's eyes suddenly lit up and he muttered to himself.

He has always been a vigorous and resolute person, and when he thought of this, he immediately ran the spirit refining vajra technique, but his soul body was extremely stinging, and the pain went deep into his soul.

He almost fainted in pain, and hurriedly stopped refining the spirit vajra.

Han Feng learned from the pain, silently pondered the reason, and thought about it, it should be caused by the lack of meridians in his soul body, and it was not suitable for cultivating the spirit refining vajra technique at all.

After resting for a while, he began to practice the Yao Sun Tongtian Technique, which led the aura of heaven and earth into the soul body, but it could not be contained, like a bamboo basket drawing water, all of it leaked out, and the aura returned to heaven and earth.

Han Feng smiled bitterly, and could only give up this idea a little helplessly.

He stood up and flew to the cultivation area of the Eight Rank Spirit Materials, and found that after more than forty years of growth, they still failed to blossom and bear fruit.

Han Feng once wondered if there was a congenital problem with these eighth-grade spiritual materials, which caused them to grow so slowly.

He turned his head and went to the spiritual herb medicine garden of the other grades, and saw that a large number of fourth- and fifth-grade spiritual materials were ripe, and the fragrance of flowers and fruits filled the whole world, shining brightly.

He picked up these spiritual materials that were ripe for a long time, and did not rush to use them, but reclaimed a large number of medicinal fields, all of which were sprinkled as spiritual seeds, and the planting area expanded by more than ten times.

After completing all this, he quickly returned to the central area, and since he was unable to practice the Spirit Refining Vajra Technique and the Yao Sun Tongtian Technique, he turned to study the Soul Ploughing Technique, focusing on soul power cultivation.

The aura of heaven and earth here is rich, and it also contains sufficient special energy factors, which can make him cultivate his soul twice the result with half the effort, and the progress is extremely rapid.

Before you know it, another decade has passed.

Han Feng's soul power cultivation has made great progress, and at the same time, he has mastered the drawing of a variety of ten-grade runes, and the casting speed is also extremely fast, almost a ten-grade rune appears with a wave of his hand, if he is fighting against the enemy, throwing out a large number of ten-grade runes is definitely a big advantage.

He tried to draw eleventh grade talisman in the air, but he worked hard for a long time, but he couldn't succeed, the difficulty was beyond imagination, the rune path was complex and long, and he also needed to cross six abysses and resist more than thirteen lightning, his best result was only to go to the thirteenth lightning, the last lightning was purple, and the power was so great that it directly collapsed the entire rune, and even the soul power phantom with him was also wiped out by itself, and he didn't have time to resist it at all.

Han Feng sighed secretly, knowing that he had no choice but to give up drawing the eleventh-grade talisman for the time being, continue to cultivate the Plough Soul Technique, and improve his soul power cultivation with his heart.

Cultivation didn't know how time passed, and in the blink of an eye, Han Feng spent three more spring and autumn seasons in this world.

A few months ago, his soul power cultivation had entered the bottleneck area, and he could no longer improve by a single inch, so he began to study the Fu Dan Lotus Method, in order to enhance the way of alchemy and enter the Four Flowers realm as soon as possible.

Han Feng gradually became obsessed and completely forgot everything about the outside world.

For several months, he pondered repeatedly and gained a little, but he had not yet thoroughly understood it, and he still needed to practice it before he could improve substantially.

Han Feng slowly opened his eyes, flew into the air, and galloped towards the direction of the medicine garden.

After a while, he came to the area where the fourth- and fifth-grade spiritual materials were planted, which had already matured and become forests, and he did not harvest them, but continued to let them survive for some years.

Then, he went to the sixth-grade and seventh-grade medicine gardens, where the spiritual materials were naturally ripe, and the year was sufficient, he picked them all and used them as spiritual seeds to expand the planting range again.

In the end, he went to the Eight Grades Medicine Garden and found that these spiritual materials had finally matured, and the medicinal power was infinite, and they were refreshing and pleasant from afar.

"It's finally ripe!" Han Feng said with a happy face, picking most of them and putting them in the storage ring.

He turned around and left the area, returned to the central position, sat down, and continued to study the Fu Danhua Lotus Method silently, contemplating it with his heart, time passed little by little, and another nine years gradually passed without him knowing.

Of course, during this period, it was naturally impossible for him to only comprehend this one exercise, but he also took turns to study the various mystical methods on the parchment scroll, even if the effect was not good, it was better than doing nothing.

Han Feng's eyes were bloodshot at this moment, and he couldn't help yawning, even though he was only in soul form now, he would also be tired.

He didn't force him to continue cultivating, and he didn't care about wasting time, so he simply lay down on the multicolored spar and fell asleep.

It took him seven days and seven nights to wake up.

During this time, he had another dream, sleepwalking through the chaos, ups and downs, seeing one world after another presented in chaos, and even he had entered several completely different worlds, but they all hurried away, like a horse and a flower, and he couldn't remember exactly what he had seen.

He woke up in a daze, and stayed for a long time before he was completely awake, but after this sleep, he found that his soul seemed to be a little stronger, which was beyond his expectations.

He rubbed his eyes, slowly stood up, and without saying a word, he flew up directly and went straight to the spiritual cultivation area.

Han Feng inspected and found that the fourth- and fifth-grade spiritual materials had all reached the maturity year he wanted, but the sixth- and seventh-grade spiritual materials still lacked some heat, so he had to continue to wait.

After a while, he returned to the central area and sat down silently on the multicolored hedron floor.
