Honestly he should give all the loot and all his possessions to every random person he sees. And he should sign a slave contract to give himself away too.
I'm betting next chapter he gets 12 more sets of "mythical" armor. or maybe just 1000 Stat point, or perhaps direct promotion to godhood. I know I'm late to the party, but I really hope his system gets nerfed at some point otherwise the book will be over before his next birthday.
