I'm About to Die at the End of the World, so I Can Only Send Relics to My Past Self

At seven o'clock in the evening on July 14, I returned to the rental house after get off work and found a bloody note on my desk. The handwriting is mine, and there are two sentences written on it: "As long as there are two or more survivors, the doomsday will continue to change until there is only one left." "The end will come on August 13th. Before you die, you can send one thing around you back to this moment." I should have thought it was a prank. But this month, the neighbor welded the security door overnight, the colleague quit his job to stock up on food, and the hardware store owner sold the generator to a man with eyes that looked like he crawled out of a mountain of corpses and a sea of ​​blood... It turns out that they are all reborn, players who have obtained golden fingers. And I have nothing. There is no system, no storage ring, no memory of past lives, only this note written with his life before his death. Every time I die, I can only send one thing away. Everything is the entire legacy of the previous me. The doomsday is getting stronger, and the reborn are getting stronger, but the one who survives to the end in this game will be a dead man who has died a hundred times and will die a hundred more times.
