My autobiography is definitely not a tragedy!

Suddenly, the mysterious book I received turned out to describe my own life?
Once I chose to change my destiny, the life within the book changed as well.
In the book, I encountered insincerity, spent ten years behind bars, and witnessed viruses laying Siege...
Cancer, bus plunging off cliffs, plane crashes, senile dementia ... even the end of days – a variety of deaths; was this fate's punishment for the rebels?
No one is a hero; it is just that this disaster-ridden fate forcibly made me into a warrior charging into battle.
Those who killed me over and over will ultimately make me stronger!
Through numerous life simulations, I amassed wealth from the financial markets, rescued innocent girls from felons, and acquired advanced technology from the future...
Although I always encounter various disasters and accidents, I still strive to flutter the butterfly's wings, changing my original fate little by little.
After countless simulations, the world too embarked on a completely different path.
However, where did this autobiography come from?
Behind it all, what kind of unknown conspiracy is lurking...
[A literary man's laid-back daily life of unlimited simulations to save the world]
