I Survived After Stealing My Memories.

This is a world shrouded in plague and zombies. People who are over 17 years old will be drawn by lottery - three-quarters of them will be sent to the front line as "line fillers", and the probability of coming back alive is less than 40%. Lin Feng's golden finger is a bead that can steal and tamper with other people's memories. He tampered with the results of the lottery and successfully squeezed into the "reserve" to avoid death. The price is: Niu Niu is screwed! The beads are also broken! The broken beads took root in another world and became Lin Feng's tree clone. He had to work as a wage earner in the world of immortality, relying on absorbing spiritual energy to give beads to extend his life. Now Lin Feng just wants to hide in the mental hospital until his legs show up, but the imperial officials insist that he is "a talent that can be made." OK! Since you can't escape, then - it's up to you, tree clone!
