I Became a Monster

A forbidden area filled with evil and deceit. When Xu Ming woke up, he found that in this strange area, he had become one of the weakest monsters, a mummy... What is going on? Xu Ming was dumbfounded. Fortunately, he also has a combat system, and he can become stronger as long as he fights. After Xu Ming thought about it, he hit a weak zombie similar to him not far away with a stick. "Ding! You attacked a low-level zombie, experience +1!" … "Ding! You absorbed a low-level zombie, and your energy is +5!" … "Ding! Congratulations on successfully upgrading. The current level is Lv.2 Corpse Creature." … … Therefore, in order to survive, Xu Ming started from level 1 zombie and carefully upgraded and evolved step by step.
