I Just Took a Nap and When I Woke Up, the Sky Fell.

Traditional cultivation of immortality, online IQ, divine power, not a holy mother, decisive in killing, invincible but not brainless! Fellow Taoists are welcome to discuss the cultivation methods of each realm. As the world's top killer mercenary, Yun Shu woke up and entered the era of spiritual energy recovery... He thought he was just an ordinary person after rebirth, but he didn't expect to have another life experience. However, after he entered the most mysterious ruins of Blue Star, he found out that he had another life experience, and that the entire Blue Star was actually his former small world, and that the golden finger of his system turned out to be his magic weapon. Everything and the system of Blue Star were set up by himself, in order to lay the best foundation for himself. In the end, the system was left behind to hide the Blue Star, and he went to the real world of immortality. Only in the real world of immortality did he understand that the world of immortality had been invaded by other worlds, and the current situation was very difficult. The purpose of his rebirth was to save the world of immortality. As he gradually became stronger, he began to support Blue Star, guide the people of Blue Star, and slowly re-established his own power in the real world of immortality. He eventually became the Supreme of the world of immortality, repaired the rules of heaven in the world of immortality, drove away the erosion of heavenly law in other worlds, and restored the world of immortality to peace. Finally, he walked out of the world of cultivating immortals and attacked the enemy world in reverse.
