It Actually Panicked After Traveling Through Time.

I actually traveled to a world where people are cultivating immortals. In this world, almost everyone is cultivating immortals, except for him. In this world, can the protagonist find the golden finger and rule the entire world of immortality? It not only integrates modern technology, but also has a world of great classics. The integration of several worlds and the confusion of time and space are really not easy. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
