Legend has it that after Pangu created the world, in order to stabilize the cosmos, the Grand Ancestor Hongjun took the Yin and Yang energies of heaven and earth, refining them into the Profound Heaven Divine Sword using the power of the universe. It stood at the pinnacle of the Nine Heavens, guarding all living beings below. One day, Donghuang Taiyi and Demon Emperor Di Jun engaged in a fierce battle in the heavenly realm. Unintentionally, they disturbed the Profound Heaven Divine Sword, which was in the midst of cultivation. The sword body and scabbard were knocked down to the mortal realm by the combined spiritual power of Taiyi and Di Jun. The sword body was reborn in the Xingxiang Town Zhou Mansion, becoming Zhou Qian, the young master of the Zhou Mansion, losing both memory and spiritual power. The scabbard, carrying memories and residual spiritual power, fell into the Peach Blossom Forest, and became known as the Peach Blossom Fairy due to her efforts to help the world.
