In the past, the Nine Heavens Immortal King Ling Jiuxiao was betrayed by his trusted aide Murong Yan; his immortal bones were crippled and his family was killed. On the verge of death, he survived by relying on the Immortal King's Order, changed his name and married into the Lu family of Yunzhou, enduring all kinds of cold treatment. Only his wife Lu Qingge stayed by his side through thick and thin for three years, guarding him gently. When the time was ripe, Ling Jiuxiao awakened and returned, leading his old subordinates to break through dangerous situations and fiercely battle powerful enemies from Tianwaitian and Xuanming. Together, the couple deployed the Nine Heavens Immortal Sealing Array, stormed the Nine-Layer Immortal Pagoda, stepped into Guixu, and guarded the three realms and ten thousand worlds. The destiny and inheritance fell upon their son Ling Nianqing, a youth who underwent secret realm trials and shouldered the heavy responsibility of guarding the gate. When the fires of war dispersed, the Immortal King laid down his authority and returned to the mortal world with his beloved, guarding a hard-won mortal perfection.
