Hong Changbao possessed two Magical Treasures, one called the Heavenly Demon Poison Banner and the other, the Five Immoral Blood Sucking Bag, both of which were the ultimate treasures with which the Red-haired Ancestor once roamed the world unopposed.
These two items were especially effective against various sects' Flying Swords and Magical Treasures, with the Five Immoral Blood Sucking Bag being the nemesis of all kinds of Gu Worms throughout the world.
The reason the Red-haired Ancestor didn't take the Green Robe Ancestor too seriously was precisely because the Green Robe Ancestor's Mysterious Yin Pearl and the Hundred Poison Golden Silkworm Gu, to which his Second Primordial Spirit was attached, were both restrained by him.
