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]

[The return of the Great Holy Spirit, blood boiling! 】 The father was killed, the family wealth was taken, all the hands and feet were interrupted, and the revenge flame was ignited, and the Qitian Dasheng inheritance was obtained. Since then, the rise of the sky, God blocked the killing, the Buddha blocked the Buddha! Qin Feng wore a gold armor and held a hand of the sea god: “I want this world for thirty-six days, and I will return to the big holy flag!”
