The sword falls into the dust and the teacher's heart returns to the moon
Undercurrents surged in the martial arts world of the Dajing Dynasty. Ling Qingxuan, the leader of the Xuanxiao Immortal Sect, was crowned the world in white clothes and swordsmanship. However, due to a blood disaster in the underworld, he rescued the orphan Su Nianyue and made an exception as his only direct disciple. Accompanying each other day and night on Yunmiao Peak, the cold sword master gradually loses his guard, and the ignorant girl develops a secret love. The bond between the master and the apprentice has quietly deepened over the years, but they cannot escape the shackles of the ancestral training of the Xuanxiao Immortal Sect's forbidden love, and even encounter the shackles of practice that hinder the sword.
Su Nianyue hides the ancient moon hairpin, which is coveted by the ghost world and becomes the source of trouble in the world. The two masters and apprentices went down the mountain to experience, venture into secret realms, and fight against evil spirits together. They share a common heart in life and death. However, due to the exposure of their love affair, they fell into the double crisis of criticism from the sect and encirclement and suppression by good and evil. In order to protect his beloved disciple, Ling Qingxuan willingly endured the punishment of the Burning Immortal Sword. His sword heart was shattered and his cultivation level plummeted. He even reluctantly expelled Su Nianyue from his school, leaving a lasting misunderstanding.
When the truth is revealed, the two know the yin and yang fate of the Chenxiao Sword and the Moon Hairpin, and also understand the century-old secret of the origin of good and evil. They broke through the shackles of the world, fused the two swords to become the Love Sword, and joined hands to lead the right path to fight against the ghostly demon soul. They defeated all laws with their deep love and defined the world with their great justice. In the end, Ling Qingxuan was relieved of his heavy responsibilities, and returned to Yunmiao Peak with Su Nianyue. He lost his identity as sword master and disciple, and finally became a couple who stayed together for a lifetime, performing a master-student love affair that transcended ethics and shocked the martial arts world.
