After the demonic light dissipated, Han Li sat back down cross-legged, adjusting his breathing to stabilize the aura within his body, a thoughtful expression on his face, pondering something.

Not long after, a few knocks came from the door. It was Shi Chuan Kong, who had come to find him after seeing that the dust had settled on this side.

Han Li got up, opened the door, and let him in.

"Fellow Daoist Li, you have been troubled by the demonic aura all these days and have remained behind closed doors. I didn't dare to disturb you rashly. Miao Xiu came twice during this period, but I made up reasons to turn her away. I was worried that if you didn't show up again, it would arouse suspicion from the San Miao tribe," Shi Chuan Kong said after sitting down.

"What is Miao Xiu doing here?" Han Li frowned slightly and asked.

"She didn't say in detail, but it seems that she will be leaving the Blacktooth Domain in a few days, and wants to visit General Gu, that is, Fellow Daoist Mo Guang, once before leaving. However, I think they probably also felt that the demonic aura fluctuations here were unusual and wanted to inquire about the situation," Shi Chuan Kong shook his head and said.

"No matter what the situation is, it doesn't matter. If she comes again tomorrow, we'll meet her again. With Fellow Daoist Mo Guang, a member of the Void Union clan, here, they shouldn't have any other ideas," Han Li said after pondering for a moment.

Shi Chuan Kong nodded upon hearing this.

After saying this, he didn't leave, but he didn't say anything else either, and the room became quiet.

"Does Fellow Daoist Shi have anything else to say?" Han Li glanced at Shi Chuan Kong and asked.

"Fellow Daoist Li, I actually have something to ask of you, but I don't know if I should say it..." Shi Chuan Kong said hesitantly.

"Feel free to speak," Han Li said.

"Can you give me another Serenity Pill that you gave me before? These days, I have to constantly resist the invasion of the demonic aura. Not to mention the huge consumption of immortal spiritual power, there are still strands of demonic aura that I can't resist, invading my body..." Shi Chuan Kong said with a frown.

"This may be a little troublesome..." Han Li said, raising his eyebrows slightly.

"I know this thing is very precious, so Fellow Daoist Li, just name your price, and I am willing to buy it with a large sum of money," Shi Chuan Kong quickly said, seeing Han Li's hesitation.

"Fellow Daoist Shi misunderstood, it's not that I'm unwilling to take out this pill. It's just that the only two pills left were used to save you, and the other was used to suppress my demonic aura backlash a few days ago. Now I don't have any left," Han Li sighed lightly and said.

"Can this pill be refined again... or are there any other similar pills?" Shi Chuan Kong's expression couldn't help but become a little黯然 upon hearing this, but he quickly asked again.

"There are no similar pills, but there are still some materials for refining Serenity Pill. I was originally thinking of refining it in a few days, but now it seems that I have to do it as soon as possible," Han Li said with a wry smile.

"Fellow Daoist Li, you must sell some to me after it's refined. Just name your conditions. Anyway, this trip to the Gray World is owed together with personal favors. I'm not afraid to add a little more. I will definitely repay you twice as much when I return to the Immortal World in the future," Shi Chuan Kong said with great joy.

"Fellow Daoist Shi, don't worry, we are now in the same boat, so naturally we must help each other," Han Li said with a smile.

The two talked for a long time again before Shi Chuan Kong bid farewell and left.

After sending him away, Han Li pondered for a moment, then sat back down and closed his eyes to adjust his breathing.

…

Night fell, and the demonic aura outside the window was pervasive, rising a layer of hazy night fog.

Han Li slowly opened his eyes, concealed the aura on his body, opened the door, and flashed out.

He passed through stone fortresses and palaces, searching nearby all the way.

After stopping for a moment in front of another stone fortress building only a few hundred feet away from the stone fortress where he lived, Han Li's figure moved quickly again, this time flying directly towards the outside of Youhe City.

He flew all the way to a dark river outside the city before landing, standing with his hands behind his back, looking at the wide river surface.

After a while, a black light fell from the sky, turning into a black flame that suddenly wrapped around, revealing a tall figure from it.

"Dao Lord Baili, long time no see..." Han Li turned to look at the person and said slowly.

The figure frowned, looked at Han Li, and asked, "Who are you? Why did you secretly send a letter inviting me to meet here?"

"Dao Lord Baili, don't be nervous, it's me. We have met several times before, but we have never spoken directly," Han Li waved his hand directly to remove the disguise on his face and said.

Baili Yan did not relax his vigilance upon hearing this, but carefully examined Han Li, and his expression suddenly changed.

"Fellow Daoist Li, is it really you? That's not right... how could you be here?" he exclaimed in surprise.

"This... to be honest, I was swallowed by an accidental spatial vortex while exploring a ruin, and that's how I got here. Dao Lord Baili, how did you come to the Gray World?" Han Li covered his aura again and said with a wry smile.

He was not surprised that Baili Yan could recognize him, after all, there was the relationship with Hu Yan Daoren.

"Hehe, my method is not as bizarre as yours. I came to the Gray World through the Samsara Palace," Baili Yan smiled.

"Through the Samsara Palace? Dao Lord Baili, may I ask what is the relationship between this Samsara Palace and the Samsara Domain?" Han Li asked with some doubts.

"This question is really difficult for me to explain... The Samsara Palace is a force in the Immortal World, and the Samsara Domain is a force in the Gray World, but there is one thing in common between them, that is, the Lord of the Samsara Palace is the Lord of the Samsara Domain. I think you understand what I mean?" Baili Yan thought for a moment and explained.

Han Li was shocked upon hearing this. He originally thought that the Samsara Domain was mostly a gray immortal force cooperating with the Samsara Palace, but he didn't expect that they were actually one family, and that the extremely mysterious Lord of the Samsara Palace was actually a powerful existence who could control the two major forces of the Immortal World and the Gray World.

Seeing Han Li's surprise and silence, Baili Yan suddenly said:

"So, you came to the Gray World by accident? It's really rare to be able to survive intact in this strange world to this day. No wonder Fellow Daoist Hu Yan praised you so much back then."

"Under the coincidence of circumstances, I have been able to hide my identity until now, which is not a skill," Han Li said, waving his hand.

"Being in the Gray World is not a long-term plan after all. The body of the immortal will be eroded by the demonic aura at all times. Once the immortal body decays, it will definitely damage the foundation of cultivation, either die or completely become a gray immortal, and the ending will be miserable. You should return to the Immortal World as soon as possible," Baili Yan said solemnly with a slightly condensed expression.

"It's not that I don't want to return to the Immortal World, it's just that I can't find a way. Otherwise, who would want to stay in this desolate world full of demonic aura?" Han Li said with a wry smile.

Baili Yan frowned upon hearing this, and after hesitating again and again, said:

"The method to return to the Immortal Domain was originally a secret of the Samsara Palace, and it must not be passed on to others... But back then in the Nether Cold Immortal Mansion, Fellow Daoist Hu Yan was able to seize the Taiyi Pill to collect karma fire for me, so that I would not burn myself to death. Fellow Daoist Han also made great contributions, and I have to repay this kindness. Take this token."

With that, he turned his hand over, and a palm-sized circular token appeared in his palm, handing it to Han Li.

"This is..." Han Li hesitated for a moment, not immediately taking it.

"This is my Samsara Token. With this thing, you can find a Samsara Sub-Hall in any lord-level city in the Samsara Domain, and they will tell you how to return to the Immortal Domain. Of course, this thing is just a path, and whether it will be successful depends on the specific situation, and you can only rely on yourself for this," Baili Yan said slowly.

Han Li took the token and looked at it for a moment, and found that its material was very special, containing strands of pure demonic aura, which was not like something from the Immortal World. One side was engraved with the words "Samsara Palace", and the other side was engraved with the two characters "Six Paths".

"This thing is too precious. I think Dao Lord Baili should only have this one, right? If you give it to me, how will you return to the Immortal World in the future?" Han Li returned the token and shook his head.

"Fellow Daoist Han should know that I introduced karma fire to my body back then, and my body has long been eroded by the demonic aura. I barely suppressed it by relying on the Taiyi Pill to enter the pseudo-Taiyi realm, so that it would not completely decay. Now that I have come to this Gray World, I am here to completely solve this matter. If I can't, then I don't need to leave the Gray World..." Baili Yan sighed and said.

"Pseudo-Taiyi Realm... Karma fire and demonic aura are from the same source, but they are just different manifestations. Why did Dao Lord Baili come to this Gray World, which is full of demonic aura, to seek a way to resolve karma fire?" Han Li was puzzled.

"The magic of heaven and earth creation is unspeakable. In this gray world full of demonic aura, there is a place called 'Demonic Cleansing Pool', which contains bone-washing golden thunder, which is the most yang thunder in time, and can break all yin demonic. If you immerse your body in this Demonic Cleansing Pool, you can wash away all the demonic aura around you, and you can also temper your body and soul, which will be of great benefit," Baili Yan explained.

"There is such a thing in the Gray World? Does Dao Lord Baili know where it is?" Han Li was overjoyed when he heard Baili Yan's words, and quickly asked.

"Demonic Cleansing Pools are extremely rare. The only one I can find out about is located in the Jiuyou Domain, which is a holy place sealed by various tribes in its territory, and no one can enter it easily. What? Is Fellow Daoist Han also interested in the Demonic Cleansing Pool?" Baili Yan glanced at Han Li and asked.

"Dao Lord Baili doesn't know, I am troubled by the tribulation of the Demonic Decline, and I am constantly hovering on the verge of collapse. I am worrying about how to solve this matter," Han Li said with a wry smile.

Baili Yan listened, looked at Han Li up and down again, especially staring at his eyes for a long time, his expression became more serious.

"Fellow Daoist Han, your demonic decline backlash is different from my karma fire returning to the body. Unless it is a matter of life and death, it is best to return to the Immortal World and find other methods. Don't consider the method I just said," Baili Yan said in a deep voice.

"Why is this again? I hope Dao Lord Baili can tell me," Han Li frowned and asked.
