Ruthless Fly [Completed]

A normal reincarnation story with a not so normal protagonist. He is smart, cunning, ruthless, and a fly. So, we have a housefly with big brains and small life. He would do anything to have a longer life and a human body for himself. Some notes- 1: This is my first story ever, so having a CERTAIN degree of criticism would be a pleasure. 2: I am a sucker for, op protags, those who use their brain, and those who don't whine about every little thing. So, expect these things in the novel. 3: The first chapter might confuse with a lot of "it"s but believe me at the end the twist will wipe all your grievances. HAPPY READING.
