Lin Xian, who was supposed to go to the world of "Under One Person", was taken to the universe of "Covering the Sky" by the system.

Lin Xian revealed a mysterious smile and asked, "Shall we slack off together, or try to fleece the main system together?"

Lin Xian pointed at Ye Fan and said meaningfully, "Follow Master Ye, and you're guaranteed to reach the Immortal King realm. The Heavenly Emperor is slaughtering everyone in front, and we're just laughing it off behind him. Isn't that wonderful?"

Immortal King Realm: Born and destroyed by the universe, eternally immortal, truly living forever, with the ability to modify the river of time on a small scale.

System 10086, who usually worked in the small worlds, swallowed hard: "Drink up!"

Simplified version: I used the Heaven-Covering Technique to suppress all the heavens and myriad realms.

He was subservient in the Nine Heavens and Ten Earths, but he launched a powerful attack across all the heavens and myriad realms!
