Did You Just Poison Me, Wife Ep. 1

Daniel transmigrates into the body of a degenerate gambler, only to wake up and realize his own wife has just poisoned him. Salvation arrives in the form of the "Daily Intelligence System", which grants him crucial foresight each day. Seizing this second chance, Daniel completely reforms, and leverages modern knowledge to introduce advanced firearms, single-handedly turning the tide of battle and earning a noble title. Yet, his greatest challenge comes not from war, but from a rift in time itself, threatening to separate him from the wife he has grown to cherish.
