Han Li's gaze lingered on the gray talisman for a moment. He noticed that the runes on it were very different from ordinary talismans, but they bore a resemblance to the patterns on the gray cloth and the gray gauze.

A thought crossed his mind, and he waved his hand, casting a magic gesture onto the talisman.

A layer of gray light appeared on the talisman, shaking the magic gesture away.

Han Li raised an eyebrow, and a golden light radiated from his palm, emitting a faint power of the law of time, touching the gray talisman, but it was still shaken away.

His expression remained unchanged. After a moment of contemplation, he activated the Demonic Qi within his body and attempted to touch the gray talisman.

This time, the gray light on the talisman flickered slightly, but then dimmed, not shaking away the Demonic Qi as it had done before.

Han Li's heart stirred, and he immediately urged the Demonic Qi to enter the talisman.

The seal structure within the talisman was not complex, and he quickly understood it, then cast a spell to break it.

A quarter of an hour later, with a soft "poof" sound, the gray talisman flashed and automatically flew off the black jade box. The black jade box opened on its own, revealing its contents: a crimson mask.

Han Li picked up the mask, slightly stunned.

He was very familiar with this mask. It was the crimson mask of the Reincarnation Child of the Reincarnation Palace, somewhat similar to his Dragon Head mask. The top of the mask had two small characters written on it: Dragon Four.

"Dragon Four, could this Gray Immortal be a member of the Reincarnation Palace..." Han Li murmured to himself.

The Reincarnation Palace mask that Jiao San gave him back then was "Dragon Five."

Without thinking too much about it, he put the mask and the jade box away, then turned his gaze to re-examine the Gray Immortal corpse before him.

At that moment, Mo Guang's voice suddenly echoed in his mind:

"Fellow Daoist Han, it seems that we're in luck. We've actually encountered a complete Gray Immortal corpse here, and its cultivation during its lifetime was probably already at the Grand Luo stage."

"Even if it was all-powerful in life, it's just a dried corpse now. Why is Fellow Daoist Mo Guang so excited?" Han Li asked dismissively.

"Fellow Daoist, you're mistaken. When I was following Ma Liang, I obtained a fragment of a scroll in a ruin. It contained some information about Gray Immortals, including a secret technique that can refine Gray Immortal corpses into external incarnations. Ma Liang always wanted to obtain a Gray Immortal corpse, but he never succeeded. I never thought we'd encounter one here," Mo Guang said.

"Is this true?" Han Li's heart stirred.

He had already witnessed the power of Mo Yu, the Grand Luo Gray Immortal, in the Underworld-Frozen Immortal Mansion. If he could possess a Grand Luo Gray Immortal clone, his chances of fighting the Grand Luo Gold Devouring Immortal would be much greater.

"I wouldn't dare deceive you, Fellow Daoist Han. These are all true facts. Because Gray Immortals are different from you cultivators. After they die, the energy contained in their bodies won't dissipate as quickly as yours. Instead, most of it will remain in their bodies, so they can be refined into incarnations. You're very lucky, Fellow Daoist, to have obtained a Grand Luo Gray Immortal corpse here. If you can successfully refine it into an incarnation, you'll have a Grand Luo stage Gray Immortal clone to fight against that Grand Luo Gold Devouring Immortal," Mo Guang said.

"Let me see the refining method," Han Li said noncommittally.

The black shadow under his feet flashed, and Mo Guang's figure emerged.

Han Li took out a blank jade slip and handed it to Mo Guang. Mo Guang took the jade slip and quickly began to carve into it, returning it a moment later.

Han Li took the jade slip, probed it with his spiritual sense, and frowned slightly.

The refining method within the jade slip was unconventional, very different from the usual methods of refining clones. It required a number of preconditions.

One of them was that the person doing the refining had to be filled with dense Demonic Qi. During the refining process, they had to inject their own Demonic Qi into several key points within the Gray Immortal's corpse in order to control it later.

The second was that the person doing the refining needed to use a Soul-Splitting Secret Technique. First, they had to split their soul, and then use a secret technique to fuse the split soul with their own Demonic Qi, transforming it into a Demonic Soul, and integrate it into the Gray Immortal's corpse.

With such double insurance, they could successfully control the Gray Immortal clone.

"The first condition isn't a problem, but this second condition, splitting the soul and transforming it into a Demonic Soul, does it cause any harm to the main body?" Han Li asked after a moment of silence.

"Splitting the soul will inevitably cause damage to the main body, and after it's transformed into a Demonic Soul, it will often transmit negative emotions such as frenzy and bloodlust to the main body. But this is unavoidable. The energy within the Gray Immortal's body is completely opposite to that of cultivators, and they restrain each other. If an ordinary soul enters the Gray Immortal's corpse, it will probably be annihilated in a short time. Only after it's transformed into a Demonic Soul can it exist for a long time," Mo Guang said helplessly.

Hearing these words, the heat in Han Li's heart slowly subsided.

If he could refine this Gray Immortal corpse into a clone with a small price, he would naturally be happy to do so, but this Soul-Splitting Technique would definitely greatly damage his soul, and it would probably also affect his sanity.

He was unwilling to bear such a price.

"If Fellow Daoist Han feels that it has too much of an impact on you, there's actually another way to solve it," Mo Guang said suddenly, glancing at Han Li.

"What way?" Han Li asked, raising an eyebrow.

"The method is simple: let me split my soul instead of you and enter the Gray Immortal's corpse," Mo Guang said with a smile.

"You?" Han Li asked, surprised.

"I am a Heavenly Demon, formless and intangible, very similar to a soul, and I naturally have a strong resistance to the energy within the Gray Immortal's body. There should be no problem entering it," Mo Guang nodded, saying so.

Hearing these words, Han Li didn't speak immediately. After a moment of silence, he said, "Fellow Daoist Mo Guang, how long has it been since we signed the contract in the Spirit World?"

"I often sleep, and I don't have a deep impression of the concept of time, but it should have been over ten thousand years. Why are you asking this, Fellow Daoist Han?" Mo Guang said, startled.

"We've been together for so many years, and you must know my character very well. I definitely won't agree to that Soul-Splitting Technique. You're helping me refine this Gray Immortal clone, and your initial plan was to enter its body, right?" Han Li said, looking at Mo Guang, calmly.

Mo Guang's expression stiffened, and he said with a wry smile, "You really can't hide anything from you, Fellow Daoist. I did want to enter this Gray Immortal corpse, but I didn't have any malicious intentions towards you. I just wanted to help you. That Grand Luo Gold Devouring Immortal could catch up at any time. If you're killed by it, my fate won't be any better."

"Oh, is that all?" Han Li raised an eyebrow.

"Of course. I also want to improve my strength. You've already reached the late stage of the Golden Immortal, and Jin Tong and the Crab Daoren have also reached the Golden Immortal level long ago. Only my strength is still at the True Immortal stage. It doesn't feel good to be left so far behind by you," Mo Guang sighed, looking dejected.

Han Li looked at Mo Guang, his eyes flickering, and didn't speak for a while.

After a moment, he suddenly raised his hand and emitted a stream of green light, enveloping the Gray Immortal corpse.

The green light fluctuated slightly, and a series of crystal-clear green threads emerged from it, wrapping around the Gray Immortal corpse, quickly enveloping it into a cyan cocoon.

The dense Demonic Qi emitted by the Gray Immortal was immediately imprisoned within it, unable to leak out in the slightest.

"We'll talk about this later," Han Li said, waving his hand and putting away the cyan cocoon.

Mo Guang nodded, his figure flickering, and merged back under Han Li's feet.

Han Li turned around and walked back to the giant rat skeleton, frowning.

Although the spiritual power within the giant rat skeleton was abundant, as one of the sources of Demonic Qi in this place, it contained extremely dense Demonic Qi, which Jin Tong and the Pixiu definitely couldn't devour.

However, this matter wasn't entirely impossible to solve.

Han Li pondered for a moment, then waved his hand and took out a stack of black formation flags and formation disks, setting them up near the giant rat corpse.

A day and a night later, a gourd-shaped formation appeared near the giant rat corpse, enveloping the giant corpse within it.

There were four table-sized black rings in this formation. The formation patterns near the rings were the densest, seeming to be the four important nodes of the formation.

Han Li chanted incantations, casting a magic gesture.

Black spiritual lights rose from various parts of the gourd formation, especially the four ring nodes, which shone brightly, rising into four black light pillars.

The four black light pillars twisted and swayed in mid-air like living tentacles.

He shouted in a low voice, and at the same time, the magic gesture he was making with both hands changed.

Immediately, the four black light pillars shot out, plunging into the giant rat skeleton.

The rolling Demonic Qi emitted by the giant rat skeleton immediately paused, and countless black runes appeared within it in the next moment.

Then, with a muffled "boom," it was as if a long-accumulated mountain torrent had suddenly erupted!

The Demonic Qi emitted by the giant rat skeleton immediately became denser again, and the speed immediately increased several times.

Countless tangible Demonic Qi surged out like a tide, spreading out, and the light at the bottom of the abyss immediately dimmed.

Seeing this scene, Han Li's expression relaxed.

This formation was based on several different formations that he had temporarily improved and designed. He wasn't sure if it would be useful, but fortunately it worked.

His fingers moved like wheels, rapidly making gestures, constantly urging the formation.

But at this moment, the giant rat skeleton suddenly shook, and the giant bones trembled, making a series of "crackling" sounds. At the same time, two faint green lights appeared in the eye sockets of the skeleton's holes, like two eyes, looking towards Han Li's location.

When Han Li was looked at like this, he felt as if he had fallen into an ice cave. His heart skipped a beat, and a layer of cold sweat broke out on his back.

He couldn't help but recall the situation in the previous illusion, where the giant rat skeleton had revived. Without caring about urging the formation, he released a great amount of green light from his body and shot backwards.

"Crack!"

The giant rat skeleton's mouth suddenly opened, and a ball of dense green shadow shot out from it, shooting towards Han Li.

The green shadow was extremely fast, far faster than Han Li. In the blink of an eye, it pounced in front of him, drilling towards Han Li's body.

At that moment, the sound of thunder rose, and countless dazzling golden arcs of electricity suddenly appeared from Han Li's body, then quickly gathered in one place, transforming into a thick golden lightning bolt, fiercely striking towards the green shadow.
