Han Feng opened it and was taken aback by what was inside, not because of the number of spirit stones in it, nor the breadth of the elixir inside, but the pieces of shining stones, almost in piles, shining brightly, shaking people's eyes.

"No wonder at that moment, that guy was such an enemy when he saw me, and he was also searching for the Yixin Stone in that area, and this pile is probably his harvest!" Han Feng thought to himself.

He casually threw down the storage ring and landed on the smooth ground with a crisp sound that was clear in the world.

"I wonder how many years I'll stay here this time?" Han Feng looked left and right, no longer had the fear of coming here for the first time, and muttered to himself.

He sat down cross-legged, took out the parchment scroll from one of the storage rings, and continued to study and practice the many tricks on it.

It was still the fire seal, and he devoted himself to it to realize, and from time to time he condensed a black fire seal of a certain size, confirming his thoughts one by one.

Cultivation has no years, and unconsciously Han Feng has been cultivating in this world for more than half a year, and the fire magic seal has been perfected by him, and with a single thought, dozens of black fire seals of a certain size will be thrown out, and the power is monstrous, even if it is an ordinary monk in the early stage of the Returning Yuan Dynasty, he has to fight with all his strength.

His soul power cultivation has also become stronger and stronger, although he has not yet broken through to the subtle realm, but the soul sea has expanded to the size of nine thousand zhang, it seems that it has reached its limit, and it can no longer be expanded.

He didn't know what such a huge soul sea represented, but he knew that he had already fallen into a bottleneck, and only by breaking through to the subtle realm could he further improve.

Fortunately, in his early years, he had read a lot of classics on soul power cultivation in the Sanye Gate, and obtained a mantra on how to advance to the subtle realm.

In fact, this is also because of his excellent performance back then, and the sect contributed a lot, otherwise he would not be able to read those classics extensively, and it just so happens that he is also a talisman master, so he has a certain privilege to browse those books that specialize in the cultivation of soul power, otherwise it is almost impossible for ordinary monks to obtain such a mantra.

Any mantra that can promote a monk to the next stage is a treasure of the sect, and it is impossible to have it without spending a lot of money.

He immediately meditated and breathed, and after eliminating all his distracting thoughts, he began to refine his soul power according to that mantra.

The sea of souls is vast, and the soul power is like fog.

As his mantra worked, a whirlpool suddenly began to appear in the center of his soul sea, and the soul power was constantly absorbed by it, spinning, and with the help of the soul power, this whirlpool gradually became larger and larger, attracting more soul power injection, and so on, and in a moment, this whirlpool became hundreds of zhang in size.

In the center of it, a little bit of colorful light came out at some point, flowing, like water.

Han Feng was overjoyed, he was just holding the attitude of giving it a try, but he didn't expect that he would derive liquid soul power so smoothly.

That's right, that little bit of colorful light is also soul power, but the form has changed, turning into a liquid state with a higher concentration, and the power will be increased by ten times or even dozens of times!

Han Feng slowly calmed down his excitement and concentrated on refining his soul power.

Since this is an independent heaven and earth, the four fields are pure, without any interference, Han Feng came in with a soul body, without half a cent of mortal qi, his heart gradually calmed down, slowly settled, like an old monk sitting quietly on the ground, from time to time at the center of his eyebrows flashed with wisps of colorful glory.

Time flies, and another half a month has passed.

Han Feng was still sitting on the ground like a rock, and the colorful light overflowing from his forehead became more and more intense, enveloping a radius of dozens of zhang, reflecting the entire world in a colorful way, like rippling water, and extremely gorgeous.

I don't know how long it took, his brows suddenly moved slightly, and the colorful light overflowing from his forehead converged, and he returned to his soul sea and disappeared.

At this moment, his soul sea has completely changed, no longer foggy, but extremely empty, only a shallow layer of colorful lake floating in the center, compared to the nine thousand zhang size soul sea space, this colorful lake is unusually small, it is estimated that there is not even a hundred zhang range.

However, the coercion of the Colorful Lake enveloped the entire Soul Sea space like a substance, firmly controlling everything.

It's done!

Han Feng opened his eyes, a colorful halo flashed in his eyes, he looked at this piece of heaven and earth and seemed to have a different feeling, in the past, when he peeked into the world, it was like a layer of gauze curtain separating it, vague, but now it is much clearer, and he can see the ups and downs of the aura of heaven and earth.

He looked at the sky above this piece of heaven and earth, and his soul power dispersed, only to see that its interior was extremely thick, and the five elements of spiritual power were gathered and colorful, and it was not at all as snow-white as it seemed on the outside.

Even he felt a powerful aura, no weaker than the old monster of the Jiedan Realm, it was hidden deep in the sky, presumably it was the jasper golden cicada that had not been seen for a long time.

Han Feng withdrew his soul power, he was in an excellent state at the moment, refreshed, and his thoughts were clear, and he immediately took out the parchment scroll and studied it carefully, feeling that his efficiency had improved a lot.

Half an hour later, he put down the parchment roll, his hands quickly pinched, the fire above his head appeared, and in the blink of an eye, it turned into a black man, less than a foot, and it continued to compress, becoming black and shiny, emitting a scorching aura, burning the aura around him with a creaking sound and green smoke.

When this black light shrank to the size of half a foot, it suddenly changed its shape, turning into an ellipsoid, suspended in the air like a huge egg, and released a terrifying coercion, shaking in all directions, and the whole world was trembling slightly!

Han Feng's eyes flickered, concentrating on changing the technique, but no matter how he urged, it could no longer be compressed, and this black gleaming ellipsoid was integrated and unmoved.

He knew that this had reached a limit again, and he might not be able to make a breakthrough in the short term.

With a twist of his hands, the spell slowed down, and the ellipsoid slowly dispersed, and finally disembodied and disappeared without a trace.

Han Feng took a short rest, and then began to study the thick soil seal on the parchment scroll again, he had practiced for a period of time before, and was able to condense a thick soil seal with a length of foot, this time after being promoted to the micro realm, he picked it up and continued to cultivate, the effect was wonderful, more than ten days later, he successfully reached the level of swaying the thick soil seal as he wanted, and each thick soil seal was compressed to the level of about nine inches, the feeling of thickness was intimidating, as if a small seal contained tens of millions of catties.

For most of the next half month, he practiced condensing this thick earth seal, and when he compressed it to the size of half a foot, it turned into an ellipsoid, like the black fire seal, dark yellow, and the surface was as ordinary as loess, but the coercion that could be emitted was like a huge mountain, terrifying!
