Time Travel: I Became the Origin of the World

My name is Su Yuan, and an unexpected success allowed me to join the army of time travellers. Due to the accidental death of the previous world origin, I actually became the world origin in his place. After seeing his diary during his lifetime, I couldn't help but make up my mind to improve the world. It's just that there's something strange about this world. Why are there so many protagonists in this world? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
