In the game pokemmo, Magikarp evolved into Tyrannosaurus rex through hierarchical evolution. When Magikarp reaches level 20, it will automatically evolve into Tyrannosaurus rex. This is a conventional way of evolution, and players do not need to use other auxiliary tools. Magikarp is a common treasure dream. The evolved Tyrannosaurus rex has higher combat capability, and players can choose to cultivate it to enhance their strength.
