"Lord Lu Hong's eyes are sharp. I was just about to report to the Domain Lord that these three are indeed not from my San Miao tribe. They are from the Xu He tribe of Shao Hao Domain. They also contributed greatly to repelling the Ni Ci Tuo Domain, and are considered benefactors of my San Miao tribe. They expressed a desire to go to Shura City to witness the grand occasion of the three-domain alliance, which is why I brought them here," Miao Gao said to the obese old man.

"The Xu He tribe of Shao Hao Domain!" The other lords were stunned upon hearing this.

"Lord Miao Gao, this alliance concerns the vital interests of our Black Tooth Domain, and various forces are gathering in Shura City. Every move is of great significance. How can you arbitrarily bring people from other domains along?" The obese old man frowned, somewhat dissatisfied.

"It's fine. I see they all have San Miao guest tokens, so they can be considered people of our Black Tooth Domain. I see that these three are all quite strong. Miao Gao, you might as well put in more effort. If you can really win them over, it would be a good thing for our Black Tooth Domain." Miao Gao's face darkened, and he was about to speak when the Black Tooth Domain Lord spoke first.

"Yes, I respectfully obey the Domain Lord's command." Miao Gao's face lit up, and he bowed to accept the order.

Although the obese old man was still somewhat unwilling, he couldn't say anything more after the Black Tooth Domain Lord spoke.

...

After Han Li and the others left the main hall, Miao Xiu warned the three of them about some things to be aware of in Black Tooth City, and then they dispersed to act separately.

Shi Chuan Kong bid farewell to Han Li and the others, then plunged headfirst into some of the city's markets, seemingly to find something to make money.

Mo Guang did not wander around, but immediately returned to the ship.

Han Li was quite interested in everything in the Grey World. After wandering around Black Tooth City and collecting some information about the Grey World, he also returned to the ship and hid in the Flower Branch Space.

"Li boy, the Grey World is going to hold a three-domain alliance?" As soon as Han Li sat down in the Flower Branch Space, Shi Qinghou's voice rang in his mind.

"That's right. The three domains seem to be negotiating at the alliance to decide whether the Grey World should invade the True Immortal Realm," Han Li said with a twitch of his brow.

"Oh, they are discussing this matter, interesting. But why would a True Immortal Realm cultivator like you want to participate in this? Could it be that you plan to go and gather intelligence?" Shi Qinghou said with a slight smile.

"I am just a small figure in the True Immortal Realm, and I am not concerned with such major events. I just heard that there is a Cleansing Pool in Shura City that can cleanse the evil aura within the human body. I am going to Shura City to find this pool and use it to get through the evil decay," Han Li said, his eyes flickering, not concealing anything.

"You want to find the Cleansing Pool? No wonder. I've heard of such a place in Shura City before. Li boy, don't expect me to help you with anything. Although I have a feud with Yin Chengquan, I've never been to Shura City, so I don't know where the Cleansing Pool is. You kid, don't think that just because you possess the law of time and have good strength, you can recklessly take risks. To be blunt, although I promised to help you, don't blame me for not keeping my promise if you insist on seeking death yourself," Shi Qinghou snorted and said.

After saying this, Shi Qinghou's voice fell silent again.

Han Li frowned slightly upon hearing this.

He told Shi Qinghou about this matter because he wanted to inquire about the Cleansing Pool, but he didn't expect that the other party didn't seem to know much about it.

However, the Cleansing Pool has a good reputation. As long as he enters Shura City, he doesn't believe he can't find out its location.

As for Shi Qinghou's words, Han Li didn't take them to heart. Now that their fates are linked, once they enter Shura City, Shi Qinghou will have no choice.

Moreover, it would be good if Shi Qinghou could help him. It doesn't matter to Han Li if this person doesn't make a move. He relies on himself for everything and doesn't depend on anyone.

His eyes flickered, and then he closed them.

The Black Tooth Domain Lord and Miao Gao and the others discussed for two days. On the third day, early in the morning, everyone gathered in the square in front of the Domain Lord's mansion, boarded a five-story ship made entirely of a black jade stone prepared by the Black Tooth Domain Lord, and set off.

...

Time passed, and more than thirty years had passed in a flash.

At the end of the horizon stood a huge black city wall, hundreds of feet high and stretching for thousands of miles, casting a huge black shadow under the setting sun.

Where shadow and light met, a huge black ship slowly descended. Dozens of figures flew down from it, but they were not in a hurry to head towards the city gate.

After the Black Tooth Domain Lord flew down from the ship and waved to put the ship away, everyone walked towards the city gate together.

Han Li and his group of three, dressed in San Miao tribal costumes, walked in the middle of the team.

"Is this Shura City? Tsk tsk, it's indeed majestic and extraordinary, unlike anything else. It's one of the largest cities in the Grey World, right?" Shi Chuan Kong's eyes flickered slightly, and he praised.

Han Li looked into the distance and saw various strange runes engraved on the city wall, which were very different from what he had seen in the Immortal Realm. There were also faint fluctuations of evil aura emanating from it.

At the huge city gate, there was a large crowd of people gathered, seemingly lining up to enter the city.

Han Li's team slowed down more than a hundred feet away, and the teams of various tribes that were entering the city one after another had already lined up to this side.

At a glance, Han Li saw that there were a total of hundreds of guards stationed next to the three arched gates.

Almost all of them were wearing gray robes that dragged on the ground, their feet hovering a foot off the ground, so they were taller than most tribespeople. Without exception, they all had a cold expression on their faces.

In terms of appearance, they were quite similar to humans, except that they had gray-white scales from below their eyelids all the way to their cheeks, which looked somewhat similar to snake sloughs, making people feel uncomfortable.

"These guys seem to be from the Nine Nether Clan?" Shi Chuan Kong glanced at these people and said.

Han Li was also puzzled when he heard this.

The Nine Nether Clan is the ruling race of the Nine Nether Domain, and their patriarch is the Domain Lord of the Nine Nether Domain, so their status is glorious. Usually, they wouldn't be doing guard duty, but today, they are all Nine Nether Clan cultivators, which is indeed somewhat unusual.

"They can't be considered Nine Nether Clan people. At most, they can only be considered Nether Slaves, which are inferior branches eliminated by the Nine Nether Clan, and are a servant race that serves the Nine Nether Clan people. In fact, the number of true Nine Nether Clan people is very small, and almost every one of them is a cultivation genius, so they are very proud in their bones. See, those few people under the city gate are the true Nine Nether Clan people." Miao Gao heard Shi Chuan Kong's words, turned around, and said to them.

Han Li looked as he was told, and saw an old man with sunken cheeks and a thin figure sitting on a black chair under the city gate. He was wearing a black robe, and his appearance looked almost the same as those Nether Slaves, except that there were no snake slough-like scales on his cheeks.

The old man, as if to subdue the various tribes gathered in front of the city gate, did not conceal the terrifying aura on his body at all, which was comparable to that of a Late Taiyi cultivator.

Next to him, there were also two people standing in the air, their expressions arrogant, all wearing black robes, floating one foot in the air. Because they were already quite tall, people had to look up at them.

Seeing the teams of various tribes in the Black Tooth Domain approaching the city gate, the leading cultivator only raised his eyelids and glanced at them, still sitting motionless on the black chair.

Among the two people hovering beside him, there was a slightly obese one who moved and floated over.

"Everyone from the Black Tooth Domain, please follow me and enter the city through the side gate." The man came close, said in a sinister tone, even saving the trouble of greeting them, and directly wanted to lead them into the city through the small door on the left side of the main gate.

The Black Tooth Domain Lord frowned slightly, and a trace of displeasure seemed to flash in his eyes, but he didn't say anything.

However, the various lords under the Black Tooth Domain were all very angry, and they cursed in low voices, but no one spoke loudly. After all, they were on someone else's territory, and they had to keep their tails between their legs.

The group was led to the left side of the gate, and saw a long queue in front of them, seemingly some tribes from a certain region of the Samsara Domain, who were entering the city one after another.

Han Li's group of three and Miao Gao were walking in the middle of the Black Tooth Domain team, walking slowly.

"Fellow Daoist Li, something seems wrong. They seem to be verifying identities here." Shi Chuan Kong suddenly reminded through voice transmission.

As soon as he finished speaking, he heard Miao Gao also say: "These bastards, not only do they make us go through the side door, but they also want to verify our identities. What do they take us for?"

Han Li shifted his gaze and saw a person in front of the gate holding an octagonal black prism. The outer frame seemed to be made of some kind of metal, and there were still many fine textures visible on it. The mirror surface was like black crystal, shimmering with light.

Whenever someone walked to the gate, that person would look at their eyes through the octagonal prism.

However, no one was checking at the city gates in the middle and on the right.

"Fellow Daoists, this thing is called the Nether Probe Mirror, which is a kind of exploration magic treasure that is particularly effective for detecting changes in evil aura. Through this object, the coagulation status of the evil aura in the eyes of the person being checked is completely visible. They can even distinguish their ethnic origin based on subtle differences in the pupils," Mo Guang suddenly transmitted his voice.

"You recognize it?" Han Li said with some surprise.

"These days, you have been checking various Grey World materials, and I have not been idle either. I have still read some books. There is a record in an ancient book called *A Record of Strange Goods*. Do you want to see it?" Mo Guang said with a smile.

"Then, in your opinion, will our disguise be discovered?" Han Li asked with a frown.

"My body is originally that of a Xu He tribesman, so they can't detect anything. Fellow Daoist Li, you have been troubled by evil decay for a long time, and your pupils have already changed. There is also evil aura entrenched in your acupoints, so now you are blessed by misfortune and should be able to get away with it. It's just that Fellow Daoist Shi... is a bit troublesome," Mo Guang slowly transmitted his voice.

Shi Chuan Kong's expression tightened when he heard this, and he showed a pensive look.

The various tribes in the queue in front of them walked into the gate one after another. The queue seemed very long, but the speed of travel was not slow. Soon, it was the turn of the various tribes in the Black Tooth Domain.

Due to his noble identity, the Domain Lord naturally did not need to be checked. He just showed the Domain Lord token that symbolized his power, and he could enter the city. After him, whether it was the patriarchs, lords, or elders and retainers of various tribes, they all needed to be checked by the Nether Probe Mirror.

After the people from the Black Tooth Domain were checked, they did not immediately enter the city, but all waited with the Domain Lord inside the gate. After everyone had passed, they would enter the city together.

Before long, it was the turn of the six people from the San Miao tribe.
