Sole Cloud Flying Cave

Cui Heng was transmigrated to another world and the system told him that the new world he was in was a high-grade Xianxia world.
It was a world where Celestial Kings soared the sky and terrifying monsters ruled the lands. The strong would destroy a planet if their mood was bad and Cui Heng trembled in fear when he learned of how scary the new world was.
Thankfully, the system had granted him the protection that last for 300 years. As long as he remained in the safety zone, he would not receive any damage.
With his safety secured, he began his cultivation training for the next 300 years.
Throughout the years as he trained, some people entered his safety zone by mistake.
There was a peasant who was once a monk and a beggar. Despite that, he still had the dream of bringing peace to the land and saving the lives of millions.
There was a noble who was once called the once-in-a-million-year genius. Yet, luck wasn't at his side and his talent fell and was laughed at by others for years.
There was a princess whose only wish was to find her older brother. She could've become a celestial but decided to remain in the human realm to wait for her brother's return.
There was a weak lady who was plagued with illness from birth but had the goal of adventuring and helping the poor and weak.
...
Cui Heng befriended these people and even gave them a few pointers before they left.
300 years later, when the protection period had ended, he had finally mastered the Golden Core. Even then, he was still reluctant to go to the outside world.
But when he did, he realized that the world was merely a world of Wuxia.

Realizing This Is A Wuxia World After Cultivating For 300 Years

As the core of the team, there would not be any differences in the level of communication. He could still establish a normal communication relationship and not affect his cultivation.

"Teammates?" Fang Yuluo noticed this description. After thinking for a moment, she said, "Do we have to complete the missions that the Samsara Lord mentioned together?"

The other three also looked at Cui Heng.

"That's right." Cui Heng nodded and said seriously, "Just as the Samsara Lord said, there are endless opportunities and fortune here."

"No matter what you want, as long as you have enough merit points, you can exchange for it. And the source of merit points is to complete the mission issued by this big light ball."

"These missions might come from different worlds. There are all kinds of dangers and we will encounter all kinds of unexpected experts, so the mortality rate is extremely high."
