I, a cultivator, have ended up in the world of tomb raiding.

The cave was dimly lit, and the ancient texts were difficult to understand. Li Yue didn't have time to study them carefully, so he just flipped through a few books and put them down.

However, these ancient books, which record the methods of accumulating yin energy to refine elixirs, have some reference value.

At least it would allow him to get a glimpse into the world's understanding of cultivation and alchemy.

The saying goes, "Do not belittle the words of a person of low status."

The Dan Palace was where emperors used to refine elixirs.

Although the methods of alchemists and alchemists in refining elixirs are abstract, the fact that they were able to set up this extremely yin place suggests that they must have inherited some knowledge and experience.

Now that I have turned to Yin cultivation, it won't hurt to learn more about these things.

It's fine if there's no storage space, but it also provides convenient storage for your belongings and you don't have to worry about it being too heavy to carry.

He was selective, taking away some of the useful scrolls and storing them in the storage space.

After confirming that there were no hidden dangers on the floor, he returned to the first floor.

A futon was placed in front of the statue of the Medicine King, who was holding a bottle of pills.

Li Yue, without any taboos, sat down cross-legged.

Taking advantage of the rich yin energy underground, he prepared to meditate and cultivate here.

He raised his hand and formed a hand seal, his fingers bending and stretching in a zigzag motion, releasing all the dozen or so human head puppets he had been holding.

One after another, gray-white phantoms slowly floated in mid-air, arranged in a circle according to the spell, and quietly surrounded him.

These Yin puppets do not yet have complete bodies; they only have distorted human faces.

A wisp of mist trails below, faces either sorrowful or ferocious, eye sockets hollow and black, a heavy, lingering aura of yin energy.

A dozen or so illusory heads hung in mid-air, swaying slightly, creating an exceptionally eerie scene.

Arranged like this, the surrounding air seemed to grow colder, exuding a chilling and eerie aura that made strangers feel unapproachable.

After doing all this, Li Yue cleared his mind of distractions, calmed his mind, closed his eyes, and began to regulate his breathing and introspect.

The dense Yin energy that had been absorbed in front of the bronze alchemy furnace was now floating on the surface of the Qi Sea.

Because it hasn't been refined, it's still wandering around in a chaotic state.

Li Yue focused his mind on his dantian, and the Yin energy that had been dissipating outside returned to its source like a tide, slowly flowing through his meridians.

Those mixed and yin energies flowed between the muscles and gently returned to the dantian.

The originally restless and chaotic cold power was refined and impurities removed by its own Daoist principles time and again.

Excessive and scattered energy settles down, and impure and malevolent energy dissolves one by one, transforming into one's own original Yin energy, nourishing the meridians throughout the body.

This is the process of refining Yin energy.

After all the surface-level free Yin energy had been refined, Li Yue, without opening his eyes, formed a hand seal with his fingertips and slightly moved his divine sense.

A nearby, lifeless-faced puppet head was suddenly drawn by magical power, breaking away from the encircling formation and drifting towards him, stopping a few inches in front of him.

Immediately, a wisp of grayish-white mist rolled in and transformed into fine wisps of smoke, which entered Li Yue's body without any hindrance.

The moment the Yin Puppet entered the body, a chill first spread through the limbs, then instantly dissipated, and the cold energy flowed through the meridians and permeated the entire body.

Earlier, when he devoured the corpse puppet inside the well wall, Li Yue was suspended in mid-air and could only absorb it quickly, without having the opportunity to calmly sense it.

At this moment, the two forces merge, and the Yin energy hidden within the body rises to the surface without any waste, returning entirely to the dantian to enhance one's cultivation.

Li Yue planned to refine the Yin energy here and attempt to break through to the next level.

Given the yin-gathering pattern of this place, if yin energy is absorbed on a large scale, it may disturb the underground energy, causing the lurking poisonous insects and evil spirits to become restless and prone to causing unforeseen changes.

After a moment's thought, he activated his spirit pet ring with his divine sense and whispered, "Nuqing, protect me here."

As the light shifted, the Angry Rooster appeared, shaking its magnificent plumage. Its phoenix eyes scanned the surroundings warily, indicating that it was now in a deep and chilling situation.

"Oh—" it whimpered softly, raised its head in response, and strode proudly to stand in front of it.

His golden eyes were sharp as swords.

"It seems that the Angry Sun Chicken also refined the spiritual energy of the flesh fungus in its spirit ring."

Seeing that the Angry Rooster was in much better spirits, Li Yue felt relieved.

He instructed the Angry Rooster:

"The surrounding yin energy will be disturbed later, and evil things may appear. You are naturally able to resist poisons and gu. If anything gets close, drive it away. If you are not strong enough, then let out a warning cry."

The Angry Sun Rooster raised its neck, its crimson comb gleaming, and nodded.

Seeing that the divine rooster's wings were taut, as if it were already in a defensive posture, Li Yue closed his eyes and focused on refining the corpse puppet in front of him.

The Ping Mountain Underground Palace is not a place for cultivation.

Normally, cultivators should meditate, refine their skills, and break through their cultivation levels in a secluded quiet room or a private cave.

Only by conserving one's vital energy and isolating oneself from external disturbances can one safely draw in yin energy and avoid the harm of vital energy leakage.

However, given the current situation and time constraints, he had no choice but to leave the Angry Rooster to guard his side.

To prevent the internal energy from becoming disordered when absorbing yin energy, which could attract evil spirits and disturb cultivation.

At this moment, the rooster, with its robust physique, stood proudly to one side.

When the golden eyes saw Li Yue, they were instantly filled with shock.

As a descendant of the ancient phoenix, its intelligence is dozens of times greater than that of ordinary creatures.

Moreover, it was born with the ability to see evil spirits, and at this moment, all the human head puppets floating around it were in its sight.

At first, I was just curious, tilting my head to look, not understanding why my master was imprisoning these remnant souls.

But as Li Yue absorbed the Yin puppets one by one, swallowing the gray-white phantoms into his body, his curiosity slowly dissipated, turning into deep shock.

The phoenix, being of yang nature, can suppress yin evil spirits, and it instinctively abhors such ghosts.

Seeing Li Yue continue to devour, the Angry Sun Chicken shook its fiery red comb, its eyes filled with surprise and uncertainty.

……

At the center of the Yin Puppet, Li Yue's expression was shrouded in a faint Yin mist. He formed a hand seal with his fingertips, successively summoning the remaining phantoms.

A chill emanated from his body, lingering around his shoulders and hair, making his cold expression and indifferent demeanor seem somewhat eerie.

His overall demeanor became increasingly reserved and profound.

One after another, tattered wisps of yin mist entered his body, and Li Yue sensed the yin energy within him continuously increasing layer by layer.

The dormant Qi Sea was once again filled.

When ordinary cultivators absorb evil influences, their meridians are inevitably affected, causing tearing and swelling pain. Even righteous cultivators who ingest spiritual medicine must endure the pain caused by the effects of the medicine.

However, Li Yue's physical body had already formed the foundation of the Core Formation, and his meridians were wide and resilient, having long since passed the most difficult stage of refinement.

The power of these Yin puppets entering the body is like drinking a mouthful of icy mountain spring water.

The coolness travels through the meridians, the slight tingling and itching disappears in an instant, and the discomfort is negligible.

One head, two heads, three heads...

With each Yin Puppet he devoured, Li Yue could clearly sense the subtle changes within his body.

The Yin energy within his dantian became increasingly mellow and complex, and the originally loose Qi flow became increasingly condensed.

A full cup of tea's time passed.

He slowly opened his eyes, and all the wandering human head puppets around him had disappeared and merged into his body.

Li Yue's breathing was steady. He opened his mouth and exhaled a wisp of pale white mist, which was cool and quickly dissipated with the wind.

With a thought, the virtual panel reappeared.

[Yin energy detected in the surrounding area...]

[Analyzing... Yin energy concentration 41%... Corpse energy component 23%... Death energy component 12%... Evil energy component 6%]

Should it be consumed immediately?

As Li Yue scanned the data with his divine sense, he pondered to himself.

Along the way, from the heart of Dan Palace to the foot of this Corpse Cinnamon Tree, it was indeed the place where the Yin energy was most concentrated in the entire Ping Mountain.

The aura of death and the aura of the dead were intertwined and mixed together, far more concentrated than in other palaces and pavilions.

Sensing the accumulation of Yin energy within his body, and estimating that absorbing all the Yin energy from the Ping Mountain underground palace would be enough to break through to the next level, he silently recited in his mind: Devour.

The next moment, invisible vortexes of energy appeared around Li Yue's body.

The pulling force of Yin energy spread from the Danjing Well to the Wuliang Hall, and then extended to the entire underground palace.

A chilling wind swept through them, causing the Xieling bandits and the three Banshan bandits who had just arrived in front of the Wuliang Hall to get goosebumps almost simultaneously.
