Genius Military Doctor: Good Morning, Major General! - Chapter 15

Akun, along with his classmates, was summoned as heroes by a goddess to save the world from the demon king. Akun, doubting he has what it takes to save the world, asks the goddess to send him back. Little did he know that this request infuriated the goddess. “How dare a mere mortal go against my will,” she thought to herself while maintaining her facade. She opens a portal for him to go back. Little did he know, the goddess had something else in store for him. As he passed through the portal, his soul was separated from his body, and he fell through the sky and earth until he landed in the body of an ant in the godforsaken forest. Left there to die by the hands of the goddess, Akun awakens the “Endless Evolution System.” [Ding!! The Endless Evolution System has been activated!!
