Start from Big Fish Eating Small Fish and Become the Master of the Dimension

Zhou Zhun, an unemployed young man, accidentally started a dimensional adventure while playing "Big Fish Eats Small Fish". In the game where big fish eats small fish, you transform into a shark and pepper to fight Godzilla. In the historical plane, you act as a master and bravely fight through the Holy Grail War of the Three Kingdoms. In the world of mortal cultivators, you become passers-by and cross-border to support the strange immortals, starting a battle between the planes of the apocalypse. (PS: This work is of a slow-burning type. I hope to lay the foundation for the protagonist's abilities and the role of the golden finger before moving forward. The pace may be slow in the early stage, and the pursuit requires a little more patience. At the same time, everyone is welcome to give suggestions in the comments. I will read them)
