The Rebirth System Restarted for Me Ten Times

Because of an accident, I traveled through time. The difference is that I had the opportunity to travel through time novels ten times, and each novel was different. Different tasks every time Only by completing the final mission can you accumulate strength and return to the real world. If you fail, you can only open another book. The scariest thing is that the content of the novel may or may not be something I have read, and my role in it is not fixed. How on earth can I reverse my fate? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
