Regarding this phenomenon, Yun Hanshuang understood that Old Monster Profound Yin had done it deliberately; only after raising his cultivation could he see the later content.

Yun Hanshuang sat down cross-legged on the spot. He wanted to study exactly what kind of cultivation method the Profound Yin Formula was.

The Profound Yin Formula, a yin-attribute cultivation method, a gradeless method, suitable for those with ice or yin spiritual roots to cultivate.

Because the Profound Yin Formula was a set of extremely yin-attribute method, it had a flaw that was neither too big nor too small. It was that regardless of gender, once one began cultivating this method, he or she would directly lose all desires of passion. Not that they couldn't use it, but they would simply no longer have that kind of desire. To break this flaw, there was only one way: cultivate the Profound Yin Formula to its highest level.

After reading through the introduction of the Profound Yin Formula, Yun Hanshuang understood why Old Monster Profound Yin had said that whether to cultivate this method or not was up to him.

After much deliberation, Yun Hanshuang decided to cultivate it, because this method was highly compatible with his physique. He had originally been unable to cultivate at all; now that he had a chance, he would absolutely not let it go. In Yun Hanshuang's eyes, as long as he could cultivate, what did a mere desire of passion matter?

Because he still could not cultivate yet, Yun Hanshuang read the entire Qi Refining chapter of the Profound Yin Formula before standing up and walking to the stone table. He reached out and picked up the Luminous Pearl, placing it in front of the potted plant.

Suddenly, the Luminous Pearl in his hand emitted a dazzling light, and he hurriedly shut his eyes. About 15 minutes later, Yun Hanshuang dared to open his eyes. Looking at that silvery-white little tree, he knew he had entered the space within the Myriad Soil Spirit-Gathering Pot.

He examined the entire space inside the Myriad Soil Spirit-Gathering Pot and estimated the space to be about thirty mu or so. At this moment, there was only that one spirit tree within the space.

Yun Hanshuang reached out and plucked that thumb-sized fruit from the spirit tree. Then he saw that spirit tree instantly wither and turn to dust, and he was brought away from the space by a white light, appearing before the stone table again.

Without hesitation, Yun Hanshuang directly put the Revolving Yin Infinite Fruit into his mouth. As soon as the fruit entered his mouth, it transformed into a cooling sensation that spread throughout his entire body.

Yun Hanshuang clenched his fist, but he didn't notice any changes in his body. Since it was not yet a full-moon night, he could not verify the effect of the Revolving Yin Infinite Fruit either.

‘Last night was the full-moon night. The next one is still ten days away. I'll have to wait a while to see if it works. Let's first see if Old Monster Profound Yin left any other treasures besides the jade pendant.’

Since he couldn't immediately verify the effect of the Revolving Yin Infinite Fruit, Yun Hanshuang decided to first check whether Old Monster Profound Yin had left any other treasures for him.

After opening the box, inside were a jade pendant and three small beads. Apart from these, there were also two sheets of beast-skin paper.

Yun Hanshuang took out those two beast-skin papers and quickly read through the contents on them.

On one of the beast-skin papers, only a single sentence was written.

Always remember what you cultivate immortality for.

Upon seeing this sentence, Yun Hanshuang immediately thought of Old Monster Profound Yin's words: another world, the river of time. These were things he could never have imagined before, and a goal gradually surfaced in his heart.

Roaming free across heaven and earth, traveling through the myriad worlds.

Yun Hanshuang raised his head to the sky and set down his purpose for cultivating immortality.

The other sheet recorded a secret art: Sealing Spirit Heaven-Seizing Art.

The cultivation method of this secret art was both very simple and very difficult. Its simplicity lay in the fact that one merely needed to seal a spirit beast's soul into one's body; the process was also very easy.

The difficulty lay in the fact that the spirit beast's soul had to be of a divine beast bloodline, with a bloodline purity above ninety percent, and its strength had to be at the fifth-stage peak or above to barely meet the requirement.

When Yun Hanshuang read this introduction, he thought his eyes were playing tricks on him. A fifth-stage peak spirit beast was on the same level as a human at the perfection of the Spirit Transformation Stage.

This kind of legendary existence barely met the requirements, and moreover, it had to possess over ninety percent divine beast bloodline. If he hadn't met Old Monster Profound Yin, and if it weren't said that the three beads were beast souls prepared for him, Yun Hanshuang would not believe that this secret art was real, because it was simply too fantastical.

In the end, Yun Hanshuang attributed this to his own lack of experience and thus became even more determined to cultivate the Profound Yin Formula.

Sealing Spirit Heaven-Seizing Art: a person could at most seal three beast souls, corresponding to their own three souls. After sealing a beast soul into the body, they would randomly gain one innate ability that the spirit beast had when alive, and this innate ability would grow stronger as their cultivation increased.

Furthermore, they could use their attribute spiritual power to summon a physical spirit beast from within their body, and the summoned spirit beast would possess the same strength as the summoner.

After reading the Sealing Spirit Heaven-Seizing Art, Yun Hanshuang took off his long robe and wrapped the box and the Myriad Soil Spirit-Gathering Pot in it.

Arriving beneath the breach in the secret chamber, Yun Hanshuang took a deep breath, then employed his Lightness Skill. Like an ape, he leaped out of the breach in a few bounds.

‘Is this the peak of Heavenly Wolf Peak?’

After exiting the breach, Yun Hanshuang surveyed his surroundings and discovered he was on the peak of Heavenly Wolf Peak.

Roar~ Kill~

Suddenly, a beast roar and the shouts of a group of people drew Yun Hanshuang's attention.

‘Could it be that the government's troops are fighting with that giant boar?’

Yun Hanshuang jumped back into the breach. He dug a hole in the middle section of the cave, hid the wrapped parcel there, then employed his Lightness Skill and swiftly sped toward the direction where the sounds of battle were coming from.

Because he was jumping directly down from the mountain peak, Yun Hanshuang quickly arrived not far from the battlefield. Yun Hanshuang stood on a protruding rock on the cliff; below him was the place where the giant boar and the troops were fighting.

Within his field of vision, Yun Hanshuang estimated that the troops numbered around five thousand, while the boar herd was now down to just that giant boar, which looked extremely bedraggled. He didn't know how the troops had managed it. From when he entered the secret chamber until now, only about three hours had passed. Yet they had not only cleaned out all the ordinary boars but had also driven the giant boar to its current state.

At this moment, the giant boar's four legs were all entangled by chains as thick as a thigh, severely restricting its movement.

Although the giant boar had yet to fully transform into a spirit beast, it was close, so even with its movement restricted, the troops could not harm it in the slightest. Thus, both sides were locked in a stalemate.

Roar~

Its underlings had been poisoned, its movement restricted, and the humans clad in iron continued to attack it without cease. Most importantly, the cold qi that allowed it to evolve had vanished—it must have been done by the human who infiltrated its den. Thinking this, the giant boar felt immense rage. It roared at the sky and, heedless of burning its lifespan, forced itself to transform ahead of time. Once it evolved into a spirit beast, it would surely devour all humans.

Current setting:

Cultivation levels are first divided into five major stages: Qi Refining, Foundation Establishment, Golden Core, Nascent Soul, Spirit Transformation.

Each stage is divided into four minor phases: Early, Middle, Late, Perfection.

Occupations, like cultivation, are divided into five grades, referred to by grade, e.g., First-Grade Alchemist. Cultivation methods, spells, secret arts, spirit beasts, spirit artifacts, spirit herbs, etc., are all referred to by tier, also divided into five tiers, e.g., Second-Tier Spell, Third-Tier Spirit Beast.

The common currency, spirit stones, is divided into four grades: Low-Grade, Mid-Grade, High-Grade, and Supreme-Grade. Their exchange ratio is one hundred to one.]
