The years passed slowly, and three spring and autumn seasons passed unconsciously.

Han Feng used this time to finally stabilize the realm of the four flowers, but he was also limited to the four-rank pill Long Yuan Dan, and the fifth-grade pill could not be 100% successful, and as for the sixth-grade and seventh-grade pills, there were even few, let alone refining an eight-rank pill with a four-flower state.

He didn't know if this would meet the mysterious woman's requirements, and there would be no such environment for him to comprehend after he went out, but he couldn't do anything about it, just because all the spiritual materials were consumed.

It is difficult for a good woman to cook without rice, so he can only give up.

Han Feng's mood was much more relaxed, his tense nerves were completely relaxed, and he couldn't help but yawn.

He didn't want to waste time, but he really couldn't stop sleeping, and after a good night's sleep, he might be able to fall asleep again, wander through chaos, and maybe improve his soul power cultivation.

He lay down, let out a long breath, and soon fell asleep.

In the confusion, he fell asleep again, and once again visited the major worlds like a horse, but he still couldn't see things clearly, those people and things were like dream bubbles, like water to the touch, and like flowers in the mirror, the moon in the water, and they dissipated in the blink of an eye.

His soul body sometimes grows and sometimes shrinks, just like his breath, but this piece of heaven and earth has a large number of special energy factors converging into his soul body, making it emit a thousand feet of light, reflecting hundreds of miles in a radius.

This sleep, Han Feng slept for twenty-seven days, which was an unbelievably long time.

When he woke up, he found that his soul power cultivation was actually approaching the late stage of crystallization, and in time, he would be able to overcome another bottleneck and truly advance to the late stage of crystallization.

In the cultivation realm, the further the realm, the more difficult it is to improve, whether it is soul cultivation or qi cultivation or body refining, this is the iron law!

But Han Feng broke this iron law, just because he had a remnant talisman, he was able to enter this mysterious world that changed the flow of time, and he could also improve his comprehension ability.

In his mind, the ancestral talisman was definitely an existence beyond imagination, even if it was still incomplete, it was not comparable to ordinary spiritual treasures.

Although Han Feng was extremely happy in his heart, he gradually calmed down and began to use the last remaining time to study the eleventh grade talisman.

He released his soul power, and sure enough, it was like a surging wave, and soon condensed in the air, as if he had transformed into a pen, drawing spiritual energy into ink, and began to outline the eleven-grade rune.

......

Time flies, and another two or three winters and summers have passed.

Han Feng secretly calculated that the eighty-one years he had stayed here were about to pass, and it was estimated that there were only a few months left, but he really failed to draw the eleventh grade talisman.

In fact, he also knew that he would definitely not be able to draw it now, after all, he had not yet been promoted to the late stage of crystallization, and his soul power cultivation was far from reaching the level it should be, and it was difficult to forcibly break through.

This is not like the one he broke through the middle stage of crystallization some time ago, after all, he had accumulated a lot of depth in the early stage, and with the help of the strange power of this piece of heaven and earth, and through a long period of accumulation, he was able to draw a ten-grade rune, thus breaking through the bottleneck.

However, this is not the case in the later stage of crystallization, which is more difficult and the bottleneck is more solid, which is naturally not something that can be broken through in three or five years.

As for the eleventh-grade rune, the difficulty is even higher, and even when he is promoted to the late stage of crystallization, he may not be able to draw the eleven-grade rune.

Han Feng didn't force it, he was able to enter this world, not only was he promoted to the middle stage of crystallization, but he also successfully drew the ten-grade rune, and more importantly, his Dan Dao also entered the realm of the four flowers, which already made him extremely satisfied.

He stood up, walked to the area where the spiritual materials were planted, inspected them, and picked the remaining mature spiritual materials on the ground again, and used them all as spiritual seeds, expanding the planting range again.

After he had done all this, he did not return to the central area, but began to travel around the world.

At this time, he knew how big the mysterious world attached to the remnant talisman was, enough to count thousands of miles.

In a moment, he flew to the chaos barrier of this world, and he carefully identified it, and found that this barrier was far stronger than before.

Han Feng casually struck out a Xuan Soul Sword and struck it on it, making a crisp sound, like hitting the copper wall, leaving not even the slightest trace.

He simply hit a blow and stopped attacking, after all, he didn't want to cause anything bad.

Han Feng was a little bored at this time, and when he was about to return to the central area, he suddenly remembered the jasper golden cicada that had been subdued by the remnant charm for many years, and he didn't know where it was hiding.

Han Feng thought for a while, suddenly looked up at the sky, looked at the sky high above, his eyes flashed slightly, and he immediately rose into the air and flew towards the sky.

Unconsciously, he flew to a height of ten thousand feet, but he was blocked by an inexplicable and invisible force, no matter how hard he tried, it was useless, and he couldn't break through.

At this moment, the clouds suddenly rolled up higher in the sky, and a golden light flashed, and after a while, a fist-sized cicada insect came out, staring at Han Feng with bright eyes, squeaking from time to time, as if to greet him.

Feng Feng was a little surprised, because the aura emitted by the other party was equivalent to the Jindan Consummation Realm, and he didn't know how it grew up, and his cultivation improved so quickly.

But when he thought about it, the speed of time here is much faster than that of the outside world, which is nothing, if it really corresponds to the time of the outside world, this jasper golden cicada does not know how many thousands of years it has been here.

However, Han Feng secretly guessed that it should not be like this, the problem was in the invisible barrier in the air, and he couldn't say the specific reason, but if the other party really cultivated in this aura heaven and earth for tens of thousands of years, as long as the longevity was not exhausted, the cultivation would definitely be comparable to the existence of the Transcendent Psychic Venerable, otherwise he would not be able to live for so long.

This jasper golden cicada looked at Han Feng for a while, then disappeared into the clouds again and disappeared.

Han Feng didn't stay here any longer, turned around and left, swooped down, returned to the central position again, sat down cross-legged, and continued to study the eleventh rank talisman.

He tried again and again, but he stopped at the attack of the fourteenth thunderbolt, although he went further than before, breaking through the thirteenth thunderbolt, but he felt that it should take a lot of time to completely complete this talisman.

Undeterred, he continued to concentrate on research, pondering with his heart, refining repeatedly, and making full use of the little time left here.

Any bit of time here was precious, and he didn't want to waste it.

Soon, another three months passed.

Han Feng suddenly opened his eyes from the meditation, only because he felt a strange fluctuation flooding, but when he saw everything around him clearly, he found that he had returned to the outside world.
