As the co-owner of heaven and earth, Lingxi made an exception and accepted Shen Yuan, an orphan of the demon tribe, as his disciple. Not only did he teach him swordsmanship and magic techniques, but he also used the Zhaotian Seal to cleanse him of the demonic aura and protect him. ", Full of dependence and admiration for her, this master-disciple relationship is pure and deep, the Demon Lord forged Lingxi's "Secret Order to Kill the Demon", making Shen Yuan mistakenly believe that he was the target of Lingxi's "elimination" - she accepted the disciple to monitor, and protected him in order to silence him after he became a master. This misunderstanding instantly tore apart the master-disciple relationship, and Shen Yuan, under the control of the devil, personally pierced her heart with the sword skills taught by Ling Xi. When Shen Yuan used the sword skills taught by Ling Xi and pierced her heart with the Broken Star Sword, the Zhaotian Seal exploded due to the "Sorrow of the Master Death Weapon" - half of it fell with Ling Xi's remnant soul, and the other half, carrying Ling Xi's last spiritual power and unwillingness, was scalded into Shen Yuan's palm. This scar is not an ordinary wound. It is the punishment of the "Lord Killer" by the treasure. It is also the mark of the rupture of the bond between the sword seal and the master and apprentice, like a "evidence of guilt" that can never be healed. Five hundred years later, the remnant soul of Ling tide transformed into a little flower demon and lost her memory. After Shen Yuan regained consciousness, he took over as co-leader with the guilt of "killing his master by mistake" and searched for her for five hundred years. After the reunion, he once again protected the little flower demon (Ling tide) as a master, but he did not dare to recognize her because of guilt. He could only bear the pain of "I killed the person I wanted to protect most" when teaching her how to read swords and seals. The two formed a misplaced bond of "she was ignorant and dependent, and he was burdened to protect".
Purpose: The fall and rebirth of the co-lord of the three realms. It is about the reconciliation that has been delayed for five hundred years after the "love and killing" between master and disciple.
