“I wonder if Fellow Daoist Hu San has more Fiend Origin Pills, or the pill formula for this pill? Li can purchase them at a high price, or exchange them for other items.” Han Li looked at Hu San and said.

“That’s a bit difficult! I only obtained it under very fortuitous circumstances, let alone the pill formula.” Hu San shook his head, saying with some helplessness.

“Could you tell me where you obtained this Fiend Origin Pill?” Han Li asked, unwilling to give up.

“Before I broke through to the Grand Luo Realm, I saw someone at an underground exchange meeting spend a thousand Immortal Essence Stones to bid for a bottle of Fiend Origin Pills. I conveniently took it from them and found that there were two pills in the bottle. I used one of them, and this is the remaining one. As for where this medicine came from, I have no idea.” Hu San spread out his hands and said.

Han Li heard this and lowered his head, remaining silent.

“In any case, thank you for the Fiend Origin Pill, Brother Hu. Here are five hundred Immortal Essence Stones.” He quickly raised his head, took out a storage magic tool, and handed it to Hu San.

“I already said I was giving it to you. You’re being a bit too impolite with this.” Hu San waved his hand, not accepting the storage magic tool, and stood up.

“Just accept it. He’s just like that, very casual.” Shi Chuan Kong said with a slight smile.

“Then thank you, Fellow Daoist Hu San.” Han Li didn’t decline, cupping his fist in thanks.

“I’ve been to Flowing Cloud City many times. Don’t worry about the issue of proper identities. Give me a few days, and I’ll handle it properly. But the Celestial Mirror Formation will depend on the three of you. I’ll only say one thing: do not harbor any侥幸.” Hu San said solemnly, then his figure flickered and transformed into a blurry silver light, disappearing without a trace.

Han Li and the others exchanged glances, their expressions somewhat grave.

They didn’t linger and quickly left the restaurant, returning to the inn.

……

Half a month later.

Han Li and the others arrived at Hu San’s room. Hu San had just returned, looking a bit tired, but his expression was somewhat excited.

“It seems the three of you are almost ready.” Hu San looked at the three and nodded with a smile.

Compared to three days ago, Han Li and the others were completely different except for their appearances, including the aura they emitted.

Shi Chuan Kong was now wearing a white robe, holding a paper fan in his hand, looking like a worldly young master.

The demonic aura on his body had disappeared without a trace, emitting a pure and harmonious aura.

Hot Flame Immortal Venerable had also transformed into a gray-haired old man, holding a purple cane. Occasionally, a streak of purple lightning flashed on it.

The power of fire within him had also transformed into an aura of lightning, faintly echoing the purple cane, without any flaws.

Han Li had also changed his attire, his body had grown taller, and his skin had become fair and clean.

Waves of water attribute faintly emanated from his body. Upon closer listening, there was a faint sound of water surges rolling from within his body.

During this period, he had not taken a single step outside the inn, fully refining the Fiend Origin Pill, finally gathering all the fiendish aura within his body. At the same time, he had also removed anything that could reveal his identity: the Azure Bamboo Bee Cloud Swords, the Jade Green Gourd, Crab Daoist, Essence Flame Child, and even the storage magic tools he usually used were all taken off and put into the Flower Branch Space.

Although it was through the Flower Branch Space and the situation inside should not be sensed, Han Li still tried his best to set up a formation space within the Flower Branch Space, enveloping everything, including Mo Guang, inside.

“Brother Hu spoke so solemnly earlier, how dare we be careless.” Hot Flame Immortal Venerable said with a smile.

Hu San nodded and took out three identity tokens, handing them to Han Li and the others.

This item was something shaped like a token, with a yellow color overall, seemingly made of some kind of withered wood.

Han Li looked over the withered wood token. One side had his name written on it. Although it was still the surname Li, the name had been changed again.

The other side was a six-petaled flower pattern, seemingly the symbol of a certain family or sect.

“The four of us are now elders of the Outer Sect of the Heavenly Sand Sect on Flowing Sand Continent. This time, we are acting on the sect master's orders to purchase a batch of cultivation materials from the Black Soil Immortal Domain.” While speaking, Hu San's body surface emerged a layer of blurry white light, constantly flashing and distorting.

In the distorted white light, his body slowly changed. After a few breaths, he transformed into a white-haired youth, and the aura he emitted was completely different from before.

Han Li and the others revealed a hint of surprise in their eyes upon seeing this, then nodded.

The four then walked out of the room and transformed into four rays of escaping light, flying towards the white giant peak within the city, quickly arriving at the entrance of the Flying Immortal Hall again.

It was the same as before, with many cultivators going in and out, a busy scene.

Hu San didn't enter through the main entrance, but led Han Li and the others into a side door next to the main entrance. Inside was an upward staircase.

The four stepped onto the staircase and walked upwards.

"Each of you give me two hundred Immortal Essence Stones." Hu San suddenly turned around and said to the other three.

Han Li and the others were stunned upon hearing this.

"What's it for?" Shi Chuan Kong asked curiously.

"Naturally, it's to reduce some trouble." Hu San said with a chuckle.

These words were a bit vague, but Han Li and the others didn't suspect anything. Each took out two hundred Immortal Essence Stones and handed them to Hu San.

The four quickly passed this staircase, and a white hall appeared in front of them.

Several Heavenly Court cultivators were standing inside, talking softly. Seeing Han Li and the others enter, one of the silver-haired youths standing closest immediately greeted them with a smiling face, asking, "Seniors, are you planning to ride the Inter-Domain Teleportation Array?"

The others revealed a hint of annoyance in their eyes upon seeing this, but didn't step forward.

"That's right." Hu San nodded.

"Please follow me, seniors." The silver-haired youth was overjoyed, leading the way, taking Han Li and the others through the hall and into a large hall inside.

A stone table was placed in the hall, behind which sat a broad-faced, wide-nosed man, sitting upright. A white-bearded old man was standing next to him, reporting something to him in a low voice.

The broad-faced man was at the Golden Immortal cultivation level, and the golden robe on his body was more exquisite than those of the silver-haired youth and the white-bearded old man. There was a golden dragon pattern on the chest.

Hearing the sound of footsteps, the broad-faced man turned his head to look over, and the white-bearded old man also stopped talking.

"Officer Fang, these seniors want to ride the Inter-Domain Teleportation Array." The silver-haired youth reported in a low voice.

The broad-faced man nodded, looked at Han Li and the others, and slowly said, "The rules for riding the Inter-Domain Teleportation Array, the four of you probably know them, but I still have to say it again: the teleportation fee is one thousand Immortal Essence Stones per person. But before that, first verify the identity information of the four of you, and then pass a probing formation to check your bodies before you can ride the teleportation array."

Han Li frowned secretly upon hearing this.

Hu San hadn't told them about the fee before. Unexpectedly, teleporting once was so expensive. One thousand Immortal Essence Stones was enough to buy an Immortal Artifact of the Entry-Grade, of course, it might be the lowest grade.

"We all know the rules. This is our identity certificate." Hu San said with a smile, then took out the withered wood token and handed it over.

Han Li and the others also took out their identity tokens and handed them to the broad-faced man.

The man took out a golden jade book from his bosom and waved it at the four people’s withered wood token.

A golden light flew out from the jade book, shrouding the four tokens.

The golden jade book suddenly rippled with a layer of golden light, and at the same time, rows of handwriting appeared, with images beside them.

"So it's the four elders of the Heavenly Sand Sect. What are you going to the Black Soil Immortal Domain for?" The broad-faced man asked, scanning the four people with his sharp eyes.

"We are following the Sect Master's order to purchase a batch of alchemy materials." Hu San stepped forward and inconspicuously stuffed a storage ring into the broad-faced man's hand.

The broad-faced man probed into the storage ring with his spiritual sense, and the expression on his face suddenly became much gentler.

"I see. It is hard for the four Daoists to travel a long way to the Black Soil Immortal Domain to purchase materials. The four of you have no problem with your identities. Please come with me." The broad-faced man stood up, returned the identity tokens of the four people, and walked forward, followed by the silver-haired youth and the white-bearded old man.

Han Li and the four people followed, and the group quickly arrived at another hall.

This hall was built of silvery-white jade, emitting a layer of fluorescent light, I don’t know what material it was.

In the center of the hall, there was a circular golden magic formation of dozens of feet in size. The formation was densely engraved with countless formation patterns, interwoven with each other, extremely complex.

Around the golden magic formation, eight golden stone pillars stood upright, each as tall as a person with their arms around them. Each stone pillar was engraved with formation patterns, connected to the formation below. Each stone pillar was cross-legged by a golden-robed cultivator, who was now sitting quietly with their eyes closed.

The walls on all sides were also engraved with complex formation runes, connected to the golden formation.

Above the golden magic formation, a huge golden round mirror hovered quietly, facing the golden magic formation below.

The air near the formation made a buzzing tremor, and a faint anthem-like sound echoed in the hall.

"This is the Celestial Mirror Formation..." Han Li looked at the scene in front of him, and a hint of surprise flashed in his eyes.

"Activate the formation, probe carefully, and don't miss a single bit." The broad-faced man changed his face to a serious expression and said to the eight people on the stone pillars in a deep voice.

The eight people opened their eyes, chanted spells, and played a series of golden magic tricks.

The golden magic formation suddenly spewed out a dazzling golden light, mixed with countless golden runes, forming a substantial golden beam of light, which merged into the golden round mirror above.

A series of golden lines lit up on the round mirror, spreading quickly, and soon covered the entire golden round mirror.

These golden lines form a series of strange groups, which look like a series of weird golden eyes, blinking gently.

A series of golden ripples emanated from these eyes, covering the golden magic formation below.

"The four Daoists, please walk through the formation in turn." The broad-faced man turned to look at Han Li and the others at this moment, and said.

The four looked at each other, and Hu San took the lead to step into the golden magic formation.

Buzz!

The golden magic formation fluctuated again, and the runes in the golden beam of light immediately changed, condensing into countless golden filaments, like countless tentacles, gently touching all parts of Hu San's body.

The golden light waves emitted by the eyes on the round mirror immediately brightened, merging with each other, forming a series of ring-shaped golden light waves, covering Hu San's body.

Hu San's face was calm, and he walked forward slowly, and soon walked out of the formation range without any abnormalities.

Seeing this scene, Han Li breathed a sigh of relief, and his mind turned as he watched the various changes in the golden magic formation.

"Next." The broad-faced man waved to Han Li and the three people, and said.

Shi Chuan Kong bowed his hands to the other party, stepped forward, and stepped into the golden magic formation.

Those golden filaments immediately gathered, touching his body, and the golden light waves on the round mirror also covered down.

Shi Chuan Kong's body stiffened slightly, then continued to walk forward, and soon passed the golden magic formation safely.

Without waiting for the broad-faced man to speak, Han Li stepped forward calmly and stepped into the golden magic formation.
