Su Mu traveled to a parallel world and got the apocalyptic daily upgrade system. This system can be upgraded once a day.
Ordinary ring? No, no, no, this is a space ring.
Ordinary RV? No, no, no, this is a red police base vehicle.
Toy gun? No, no, this is a high-powered rune gun and it recharges automatically every day.
So can I upgrade myself?
