I absorb everything in the United States

Introduction: Traveling back to the crisis-ridden American comics, Yasen discovered that he could absorb the properties of items.Absorb a stone to increase the body's hardness; an iron pickaxe to increase the digging speed by 100%; a knife to gain the hand blade power; a pistol to gain the unarmed shooting power! ...So, Yasen began to extend his sinful little hands to the major artifacts in American comics.What?It turns out that without the artifact, the universe would still be out of balance? !But Yassen doesn't care, this bastard only cares about himself!
