Xiu Tu

After Pangu created the sky, the overflowing divine power spilled into the world and formed divine weapons, becoming instruments of bloody conflict in the underworld. The arrows that shoot through walls, the umbrella that summons giant whales, and the spear that can turn a snowy mountain into a lake of lava... Li Cangsang and his son must defeat the masters who possess these powerful weapons, in order to find his family's true enemies and break the centuries-old family curse. (Source: Bilibili, translated)
