In his past life, Zhou Yuan practiced filial piety like a fool for half his life, yet let his wife and daughter suffer endless humiliation. In this lifetime, the money he earns will only support his wife and daughter! After leaving with nothing, Zhou Yuan takes his wife and daughter to live in a dilapidated shack at the foot of the mountain, but accidentally awakens the Tool Enhancement System: a worn-out firewood chopper, once sharpened, is enhanced into a divine weapon that cuts through iron like mud; an old slingshot, once fired, turns into a 100-percent accurate magical artifact; ordinary tools like broken fishing nets, animal traps, and hunting bows can also be continuously enhanced and upgraded.
