Reincarnated in "summon to another world again" but I'm an aura farmer

An ordinary college student whose always been a fan of aura farming while walking back to home saw a kid about to get run over by a truck, he ran as fast as he could and pushed the kid away and then got hit by the truck. In his last moment he got up enduring the excruciating pain from the impact like nothing happened. The kid afraid ran away from the spot and as the man saw the kid ran he went near the edge of the bridge "(Fuck!!! that shit hurts like fucking hell. Fuck! fuck! fuck! fuck!!!!)" was the thought on his mind but he couldn't scream not because his body didn't allowed it but he couldn't let anyone hear it."(But it's all worth it as a die-hard fan of aura farming I can't let great opportunities to farm aura like this go away even if cost my life. I can't let the inventors of aura farming down)" was the last thought on his mind before his body gave in to the injuries and falls off the bridge. Note: I don't own any of the art that are used here.
