Consciousness Is Immortal? I Choose to Disassemble the Phone

In the future world, human consciousness can be uploaded to the cloud and gain eternal life. I chose to stay in the mortal body that was about to be abandoned and started working as a "human body repairman". They mock me as a gravekeeper of the technological age, a stupid old human being. Until one day, all cloud consciousnesses suddenly went out of control, and digitalized humans fell into madness. Only I, a "waste" who can repair my body, hold the last hope of restarting the world.
