At 749, I Went on a Rampage

After transmigrating to another world, the protagonist starts with Second Senior Brother's miraculous cultivation technique for absorbing others' essence, spending a year with a thousand women. The Moon Golden Wheel becomes his blade, the Heavenly Dragon Slayer his wings, the Haotian Mirror his shield, and the Eastern Emperor Bell his hammer. Using his golden finger to manifest countless terrifying weapons from legend, he slaughters every demon and monster in his path. Anyone who stands in his way dies, be they man or Buddha. He is ruthless and decisive, with no soft-hearted saintliness.
