The 5-Second Profit System

I picked up a System Fragment, allowing travel to any world for five seconds to grab items. First trip: Wang Cai almost didn't make it back. I split loot 50/50, he got stronger. Jealous, I went on the second trip, bringing back a baby that almost overpowered me. Third trip: I hit the jackpot: a milk canister. The System Fragment is running out of power, but I've only just started enjoying the loot. Next time I travel, I'm not going to be human.
