At the Beginning, He Punched the Blood of Superman and Exploded the World!

I insist on doing 100 push-ups, 100 sit-ups, 100 squats, and 10 kilometers of long-distance running every day. After three years, I have become bald and stronger! Inherit the teacher's wish and become a hero out of interest! Don't care what others think of you, just stick to the justice in your heart! PS: Saitama-sensei is set to be invincible, so the bloodline he inherited is also invincible! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
