Mortal: I became invincible after becoming sworn brothers with Han Li.

Afterwards, Yan Yu checked the invitations of the three people according to the rules before taking them to the two small mountain peaks dozens of miles away.

Yan Yu took out a token, infused it with his spiritual power, and after the token emitted a hazy yellow light, he swept it across the void in front of him. The restriction in front of him immediately disappeared, revealing the true eye hidden inside.

It was an extremely magnificent ancient castle, with its outer walls reaching a height of thirty or forty zhang (approximately 13-14 meters), and countless tall ancient buildings inside.

"This is Yanling Fortress of our Yan family. Welcome, fellow Daoists!" Yan Yu said solemnly, his expression turning serious.

Upon entering the castle, the three immediately noticed that on a high platform resembling a dueling arena at the corner of the castle, two men dressed in different clothes were facing each other, while below the platform, on the east and west sides, stood two groups of people dressed in the same clothes.

Upon seeing this scene, both Han Li and Dong Xuan'er showed a hint of astonishment, because one group of people was clearly a disciple of the Yan family, while the other group of people dressed in green robes were actually fighting with the Yan family disciples on Yan family territory, which really puzzled the two of them.

"Fellow Daoist Yan, my junior brother and sister and I have been traveling for several days and are quite tired. I wonder if you could arrange two rooms so that the three of us can rest and recover?" A strange look flashed in Li Yunfan's eyes. Before Yan Yu could explain to the three of them, he spoke first.

"Of course, fellow Daoist, just follow me!" Yan Yu's original words of explanation were forced back by Li Yunfan, so she could only change her words.

The group arrived at the entrance of an inn called "Juxian". Through Yan Yu's introduction, Li Yunfan and the other two learned that this was an inn that specifically catered to cultivators.

"Fellow Daoist Li, I have already spoken with the innkeeper and arranged three superior rooms for the three of you. I have already paid the spirit stones, so you can rest here with peace of mind." Yan Yu entered the inn, spoke to the innkeeper, and then turned around to say to Li Yunfan and the other two who were waiting.

"Thank you, Fellow Daoist Yan!" Li Yunfan smiled and thanked him.

Afterwards, Yan Yu took Yan Ling away from the inn, and Li Yunfan also invited Han Li and Dong Xuan'er to go up the stairs to their respective rooms. However, when Dong Xuan'er opened the door, Li Yunfan once again warned her to stay in her room and cultivate, waiting for the treasure-hunting competition to begin.

He knew all too well how troublesome this troublemaker was. If he let her run off on her own, with her outstanding looks and seductive charm, who knew what kind of people she might attract?

If Han Li's number one mortal enemy, Wang Chan, the young master of the Ghost Spirit Sect, is attracted here, wouldn't that be even more troublesome!

Upon hearing Li Yunfan's words, Dong Xuan'er visibly paused, then offered no reply, instead slamming the door shut behind her as she entered the room.

At this moment, Han Li suddenly stepped forward and whispered something to Li Yunfan. After seeing Li Yunfan nod, he left the inn alone.

For the next few days, Li Yunfan stayed quietly in his room, and Dong Xuan'er, who lived next door, did not leave his room at all. Although she seemed very obedient, she had actually tried to sneak away several times, but Li Yunfan discovered and stopped her each time.

With the strength of his divine sense after cultivating the second level of the Great Evolution Technique, he could sense some anomalies in the next room even without deliberately keeping an eye on it. As soon as the other party opened the door, he would naturally discover them.

Of the three, only Han Li went out a few times during this period. He not only obtained a recipe for a "Spirit Feeding Pill" and a spiritual herb, but also learned some information about the Ghost Spirit Sect from disciples of the Qingxu Sect, the Giant Sword Sect, and other seven sects.

On this day, a loud male voice suddenly came from outside the inn.

"Listen up, guests of the inn! The treasure hunt will officially begin tomorrow. All participating cultivators will be divided into two groups, one group..."

The sound was repeated three times outside the inn before finally stopping, and the man who had shouted left the place afterward.

"It's finally about to begin..." Li Yunfan opened his slightly closed eyes and thought to himself.

However, he would never participate in any treasure hunt, because he knew it was a deadly trap, and he would never be foolish enough to walk into it.

After a moment of hesitation, he got off the bed, pushed open the door, and went to Han Li's room.

Meanwhile, somewhere in Yanling Fortress, the young master of the Ghost Spirit Sect was leading a dozen Ghost Spirit Sect disciples in preparations to annihilate the invading cultivators.

Meanwhile, in the secret chamber of Huangfeng Valley, thousands of miles away, Patriarch Linghu also told the seven or eight Core Formation cultivators standing in front of him about the invasion of the demonic path, and began to arrange the next move of Huangfeng Valley.

The next morning, Li Yunfan led Han Li and Dong Xuan'er to a small mountain peak west of Yanling Fortress, where a large array had already been built, waiting for the cultivators participating in the treasure hunt to arrive.

Li Yunfan and Han Li exchanged a glance and walked silently toward the corner furthest from the great formation.

Upon seeing this, Dong Xuan'er hesitated for a moment, but remembering what Li Yunfan had said to her last night, she followed closely behind out of concern.

"Senior Brother Li, is what you said last night really true? Has the Yan family truly sided with the Ghost Spirit Sect and planned to kill us all inside Yanling Fortress?" Dong Xuan'er walked up to Li Yunfan and asked, still somewhat disbelieving.

"If Junior Sister doesn't believe me, she's free to leave. Junior Brother Han and I won't stop her in the slightest," Li Yunfan said calmly, glancing at Dong Xuan'er.

Upon hearing this, Dong Xuan'er paused for a moment, then a hint of resentment flashed in her eyes, and she was very displeased with his cold demeanor.

"If my senior brother truly abandons me, I'm afraid he won't be able to explain it to Uncle Li when he returns to the valley!"

Li Yunfan raised an eyebrow slightly, gave her a half-smile, and then ignored her.

What could he possibly have to hide? By the time he gets back, the battle between the Seven Sects and the Demonic Path will have already begun, so there won't be any time to bother with him.

Besides, he will soon be leaving Yue Kingdom and Huangfeng Valley completely, so what is there to worry about!

Half an hour later, on a low earthen platform behind the formation, the young master of the Ghost Spirit Sect flashed a cold glint in his eyes and directly ordered the formation to be activated.

But soon, he received a message from the cultivator beside him that there were actually five cultivators outside the range of the formation, which surprised him.

After glancing at the location of the five people, he thought for a moment and came up with a solution. He then instructed the Ghost Spirit Sect cultivator beside him to shout to the cultivators outside.

"All cultivators participating in the treasure hunt will draw lots to register. Once the number of participants is tallied, the treasure hunt will officially begin..."

This shout immediately attracted the attention of the other cultivators, who all moved closer to the formation.

Only Li Yunfan, upon hearing this shout, had a glint in his eyes and immediately yelled back.

"run!"
