World view: A fantasy world (can be specifically named, such as: Tianxuan Continent) where martial arts is the most important and the weak eat the strong. The cultivation system is to absorb "mysterious energy/spiritual energy" and has distinct levels (such as body tempering, Kaiyuan, Qi Dynamic, Zhenyuan, Shendan, Yuanying, Shenhua...).
Protagonist (before time travel): Lin Fan, an ordinary social beast/frustrated young man in the modern world. His character may be a bit cowardly and resigned, but deep down he is unwilling. May die due to accident (car accident, electric shock, being smashed, etc.).
Protagonist (after time travel): With the same name or a different name (such as Lin Fan), his identity is a recognized "waste" child of a large family (such as the Lin family in Yuncheng). His cultivation has been stagnant at the lowest stage (such as the first level of body tempering) for many years, and he has been looked down upon and bullied by his tribe. The original owner may have died due to some serious humiliation or accident, causing the protagonist to travel through time and become possessed.
Gold Finger: An ancient jade/ring/broken magical weapon with an unattractive appearance, which changes as the protagonist travels through time.
