After Guarding the Sword for Three Years, One Sword Shocked Qingyun

Thousands of years ago, the seven demon gods of chaos from outside the realm invaded and devastated all life in the three realms. The first-generation Zhu Xian Sword Master sacrificed his body, activated the Four Swords of Zhu Xian to severely damage the bodies of the seven demon gods, and sealed the soul of the Demon God Lord in the Burial Sword Abyss of Ten Thousand Swords Palace. His own soul merged with the seal of the Three Realms and the Four Swords of Zhu Xian, leaving a legacy sword seal, waiting for the successor who can inherit the "Guardian Heart" to awaken. Ten thousand years later, the seal naturally weakened. In order to seek power, Canglan God King secretly destroyed the seal and colluded with the Demon God Lord to split his soul, accelerating the coming catastrophe.
