You Sent Me to Retire, So How Did I Become a Martial God?

My name is Meng Changhai. On my eightieth birthday, with only eight days and eleven hours left to live, that damned Heaven finally remembered I existed.

After binding to the "Martial God" System, I began a life of relentless grinding.

While the other old men were resting and recuperating, I was doing frog jumps.

While the other old men were drinking tea and reading the papers, I was doing push-ups.

While the other old men were taking walks, I was doing strength training.

While the other old men were dancing with the old ladies in the square, I was doing the Eighth Broadcast Calisthenics Routine.

Many years later, having ground my way into becoming a Martial God, I proudly answered the many reporters' questions.

"Everyone who lived in the same nursing home as me got old and died before I did."
