"What exactly is the miraculous effect of this Grand Yi Pill? Judging from the way Luo Qinghai and the others are eagerly pursuing it, it doesn't seem like a top-tier healing elixir." Seeing Daoist Hu Yan turn around, Han Li suddenly transmitted his voice.

"This Grand Yi Pill is naturally not a healing elixir, but a supreme-grade spiritual pill that all Golden Immortal cultivators dream of, yet can only hope for but not obtain!" Daoist Hu Yan explained.

"Its name is Grand Yi, could it really be related to advancing to the Grand Yi Realm?" Han Li said, his heart stirring.

"Indeed! The most crucial effect of the Grand Yi Pill is to help Golden Immortal Peak cultivators resist the Fifth Decay Tribulation." Daoist Hu Yan nodded.

"I see."

Upon hearing this, Han Li was secretly delighted. The importance of this Grand Yi Pill to Golden Immortals was no less than that of the Golden Soul Pill to True Immortals, and its preciousness was even greater.

And the last Grand Yi Pill he obtained was clearly the highest grade one in the entire furnace of pills, so the effect was even more self-evident.

Daoist Hu Yan put away Ouyang Kuishan's corpse and, together with Yun Ni, flew towards the remaining halberd-wielding puppet.

Han Li, on the other hand, straightened his body and, after examining his physical condition, gripped the Azure Bamboo Bee Cloud Swords in his hand, exchanged a glance with Jiao San, and signaled her to prepare to attack.

Just then, a dull rumble came from the golden seat, and the entire hall trembled.

Although the hall collapsed, the area around the seat was completely undamaged.

The corpse on the seat suddenly sat up straight, emitting an extremely dense gray light.

The golden light罩 seemed to sense something, and the golden light it emitted suddenly intensified, with countless palm-sized golden runes appearing, forming a whole.

However, this could not stop the gray light, and beams of dazzling gray light projected out from the gaps in the runes, illuminating the surrounding area with a hazy gray.

"Haha... haha..." A hearty laugh suddenly came from within the golden light罩.

The laughter was not loud, but everyone present felt a sharp pain in their minds, as if countless red-hot steel needles were piercing their souls.

Everyone present was shocked and hurriedly circulated their cultivation techniques to protect their souls, retreating backwards.

Han Li's eyes flashed slightly, and his figure also retreated swiftly.

Gongshu Jiu was also startled and, no longer pursuing the others, turned his gaze towards the golden light罩.

A white shadow flashed, and Xue Ying landed beside Gongshu Jiu, also looking towards the golden light罩 following Gongshu Jiu's gaze.

Inside the golden light罩, gray light churned, and nine wisp-like gray lights flew out from within the light罩, wrapping around the nine golden stone pillars beside the seat and gently tightening.

With a "snap," the nine stone pillars were easily snapped in half.

The golden light罩 immediately trembled violently, with cracks appearing on its surface, and then, with a "bang," it shattered.

Amidst the rain of golden light, a figure slowly walked through the air, his clothes fluttering, ethereal like an immortal. It was the middle-aged Daoist on the seat.

This man had a smile on his lips, walked with his hands behind his back, and was surrounded by a layer of faint gray light, looking no different from ordinary cultivators.

The only unusual thing was that the middle-aged Daoist's eyes were gray, without pupils or whites. His eyes were hazy, extremely strange.

Gongshu Jiu's expression changed immediately when he saw the middle-aged Daoist's face, with a hint of doubt in his surprise.

"Uncle Gongshu, do you recognize this person?" Xue Ying asked from the side.

"I didn't expect that there would actually be a Gray Immortal here. This trip was not in vain." Gongshu Jiu said, staring at the middle-aged Daoist with eyes like an eagle, with a hint of solemnity.

Luo Qinghai, Daoist Hu Yan, and the others' faces changed upon hearing these words.

Luo Qinghai retreated as if avoiding a venomous snake, waving his hand without saying a word, sending out a stream of water-like blue light, wrapping up the Cangliu Palace group, and flying away into the distance.

The white-haired Golden Immortal from Zhulong Dao also immediately retreated, increasing the distance between himself and the middle-aged Daoist.

Daoist Hu Yan and Yun Ni exchanged glances and also retreated a distance.

Seeing the reactions of the others, Han Li's heart stirred, and with a flicker of his figure, he also retreated to Daoist Hu Yan and the others' side, while transmitting his voice to inquire, "Daoist Hu Yan, what exactly is a Gray Immortal?"

Although the remnant soul old Daoist had told him some things about the Gray Immortals and the Gray Realm, he had not explained it in detail. Judging from the reactions of everyone at the moment, they seemed extremely fearful of the Gray Immortals.

"Daoist Li, you may not know this, but our Northern Cold Immortal Domain was originally called the Nether Cold Immortal Domain. In the past, due to an apocalyptic war, the entire Immortal Domain was divided into two, which is how the current situation was formed. The reason for that apocalyptic war was the invasion of the Gray Immortals. Gray Immortals are a type of existence that is hostile to immortals. As for where they come from, it is unknown. It is said that they can devour immortals. In that war, all the sects and forces in the entire Nether Cold Immortal Domain joined forces, plus the assistance of some other Immortal Domains, to repel those Gray Immortals, but nearly half of the sects in the entire Nether Cold Immortal Domain were destroyed, and many clans were exterminated. After that, there were no more reports of Gray Immortals appearing." Daoist Hu Yan said quickly.

"How come I've never heard of such a major event before?" Han Li asked, his heart shuddering upon hearing this.

"That war was too long ago, and the Heavenly Court has been deliberately concealing the matter, so now, in the entire Northern Cold Immortal Domain, only top sects such as Zhulong Dao and Cangliu Palace have some records of that war. You are young and have only been in the sect for a short time, so it is naturally impossible for you to know about such top-secret matters." Daoist Hu Yan continued.

Upon hearing this, images of what the remnant soul old Daoist had said before appeared in Han Li's mind, verifying them one by one, and he nodded.

Just then, a dark red light flew and landed beside the middle-aged Daoist, revealing Jiao San's figure, and she slightly bowed to the middle-aged Daoist to show her respect.

"Congratulations, Real Person Mo Yu, on returning to the Immortal World!"

Seeing this scene, Luo Qinghai and the others were shocked.

They didn't expect that the people from the Reincarnation Palace would also have dealings with this Gray Immortal.

At this time, Han Li's gaze towards the middle-aged Daoist also carried a hint of astonishment.

He had previously learned from the remnant soul old Daoist that the Reincarnation Palace colluded with the Gray Immortals, so he was not surprised that Jiao San was associated with the Gray Immortals.

However, he had only half believed what the old Daoist's remnant soul had said before. Now, he did not know what means he had used to forcefully occupy this living corpse, and this living corpse seemed to be the "Mo Yu" that he had mentioned.

According to what the remnant soul old Daoist had said, Mo Yu was the name of the Grand Yi Gray Immortal who triggered the Gray Immortal invasion of the Northern Nether Immortal Domain.

But what the old Daoist said was that Mo Yu was a female disciple under the seat of the Nether Cold Immortal Sovereign, but the person in front of him was clearly male.

What was going on?

Han Li's thoughts raced, and his eyes flickered.

"You are the Mo Yu from back then? So you have been hiding in the Nether Cold Palace all along!" Gongshu Jiu's face suddenly froze upon hearing these words.

"Oh, someone actually remembers me. By the way, who are you?" The middle-aged Daoist ignored Gongshu Jiu completely, as if he didn't see him, glanced at Jiao San, and said.

"Reincarnation Palace, Jiao San." Jiao San replied.

As soon as she spoke, red light flickered on her body, and her appearance and figure changed rapidly, instantly transforming into a graceful woman in a red dress, but she wore a scarlet dragon-head mask on her face, so her appearance could not be seen.

"Jiao San? This time, I owe you a favor. Tell me, who do you want to kill?" Mo Yu said, looking around.

Upon hearing this, Jiao San did not speak, but gently pointed her finger in Gongshu Jiu's direction and retreated to the side.

Mo Yu turned his gaze and looked at Gongshu Jiu, smiling slightly, but paused on Han Li.

"Boy, why are you so disheveled after not seeing you for a while? What a waste of the Supreme Laws. After this seat repays the favor, I'll chat with you." Mo Yu said with a chuckle, looking at Han Li's disheveled appearance.

Everyone else present looked at Han Li upon hearing these words, with a hint of strangeness in their expressions.

"Little Friend Li, what is your relationship with this Gray Immortal?" Daoist Hu Yan asked through voice transmission.

"It's a long story. He and I met by chance in a certain palace, and I took him out with me. Whether this person is friend or foe is still unknown." Han Li said with a wry smile in his heart, replying through voice transmission.

"Could it be that you actually entered the legendary Moonflower Palace?" Daoist Hu Yan's eyes widened.

"It seems so, now." Han Li said.

At this time, Mo Yu's gaze fell on Gongshu Jiu again.

"I, Mo Yu, always repay my kindness, so I'm sorry, Immortal. May I ask, how do you want to die?" Mo Yu said, with a hint of helplessness in his tone.

"Hmph! You have just returned your soul to its position, and your realm is unstable. You want to delay time to recover? Naive!" Gongshu Jiu chuckled, pinching his fingers with both hands. White qi churned in front of him, and ten white figures emerged, each several times larger than before, flying towards Mo Yu.

"Oh dear, this is bad! You saw through it all. Have the inspectors become so smart?" Mo Yu seemed to gesticulate for a while, but then a gray light flew out from the palm of his hand, and then he said with a solemn expression:

"Actually, to kill you, I only need one move!"

As soon as he finished speaking, with a "bang," the gray light suddenly exploded, turning into countless gray light threads, each emitting a hissing sound.

These gray light threads were extremely fast and numerous, densely covering hundreds of feet of space, instantly piercing through these white figures, leaving none out.

The ten white figures were pierced by the gray threads, their figures immediately stopped, and then they exploded in place with a bang, turning into a sky full of mist that dissipated.

Han Li and the others looked shocked. These gray threads were so powerful that they instantly extinguished the ten white figures that had caused them so much trouble.

After piercing through these white figures, the gray threads did not stop at all and continued to shoot towards Gongshu Jiu, covering the sky and earth.

Seeing this situation, Gongshu Jiu did not show any panic on his face. He spat out a ball of white light, which turned into a white ancient mirror as it spun around.

The surface of the ancient mirror emitted a bright white light, and countless runes flew out, churning and uncertain, turning into a thick white cocoon, tightly protecting his body.

Seeing this, Mo Yu changed his hand gestures.

All the gray light threads suddenly brightened, gathering towards one place, instantly turning into a gray light arrow as thick as a bowl.

A strong, cold aura emanated from the light arrow. This aura was different from any law, but it was no less than any law.

Around the light arrow, even more gray spiral-shaped light appeared, spinning rapidly, emitting a terrifying wailing sound, and the speed increased several times.
