A protagonist screamed as he coughed a mouthful of blood.

“I didn't do anything. It was your fate!” Jun Tianyun explained kindly.

“Brother Jun! Because of you, I am still alive and living a normal life with my wife and two children. You are a saint!”

A villain spoke with an emotional voice.

“I didn't do anything. You earned your chance of redemption.” Jun Tianyun sighed.

“This...” Jun Tianyun fell in dillema.

“Sigh, Changing the fate, So burdensome.”

Jun Tianyun sighed as he saw a bunch of heroines fighting for him.
