[Quick Transmigration] Let Me Die First

[Hello, Host. This unit is coded QS-233. Judging by the way life-forms think in this era, this unit should be a high-tech System from five hundred years in the future. This unit's original owner accidentally activated time travel before dying, which is how this unit came to this time period. To avoid being destroyed by the world's rejection, this unit fused with the Host's spirit in a moment of desperation. That is all. Does the Host have any questions?] "Yes. Can you leave my... spirit? If nothing unexpected happens, I should be succumbing to the poison in half an hour." It had only just found a suitable Host, and now the Host was about to kick the bucket. What was the point of that...? He'd finally managed to get that whole family killed and was just about to set off firecrackers to celebrate his impending death. Why had this System picked him...? So this is a quick transmigration story about a male protagonist who thinks the world is too boring and visits other worlds to have some fun~~ Male-receiver protagonist, firmly 1v1, lighthearted.
