Legend of Chaos Sword Demon

If you hold me in your arms, love me to the core, and protect me, I am willing to cover my eyes and not distinguish whether you are a human or a devil behind me. As long as you are good to me, no matter whether you are a god, a demon, a ghost, or a monster, you are my beloved. I am willing to accompany you in life and death. If you let me really make a mistake, I will let you break your bones and turn into ashes. There is the Sword Immortal in the east, Jian Lai in the west, the Sword Emperor in the south, and the Sword God in the north. They are known as the "Four Swords of Heaven and Earth". Guard the four doors leading to other worlds respectively. Maintain peace and justice in the world. The four gates of east, west, north and south were sealed by the Emperor of Heaven and entrusted with the four swords to guard them. Sword Demon Bai Yu, a disciple of the Sword Immortal, met and fell in love with the demon Qian Mo (a drop of surviving demon blood was attached to the bamboo when the gate to the alien world was broken and the demons invaded hundreds of years ago). The four swords of heaven and earth eliminated the demon Qian Yu, but the sword demon's plea was unsuccessful. In order to save his beloved disciple Sword Demon, the Sword Immortal spent his cultivation to seal the Sword Demon in the East Sword Gate. When the sword demon knew that Qian Mo's soul had been scattered and destroyed, the sword demon was deeply saddened. His love for Qian Mo turned into hatred for the world. Under the influence of the demon, he defeated the four swords of heaven and earth and reopened the gate to the other world. The monsters and alien races once again brought trouble to the world. The four swords of heaven and earth were imprisoned in the chaotic Milky Way of another world. The four swords of heaven and earth endured the erosion of the water of chaos, and the sword demon broke through the celestial body and wanted to unify the three realms.
