After Time Travel, I Became the Boss of the World of Immortality

There May Be a Golden Finger in the Article About Cultivating Immortals, and There Is a Background➕group Favor

I want to read a book similar to "No One Can Understand Arrogance Better Than Me". You can practice immortality, time travel, and be reborn, you can have a powerful golden finger, you can be a brainless and cool girl with or without CP. The heroine must have a strong background, don't hide her identity, and don't attack counterattack.
