Three hundred thousand years ago, the war between gods and demons swept across the wilderness, and thousands of ancient powers fell. Only the blood of the four clans, Tian, Feng, Fox, and Demon, remained in the world. The twins born directly from the Dragon Clan each share their destiny. The eldest brother Ling Yuan sits in the Changyuan Mountain of Kunlun and is the God of War of the Three Realms protecting the six realms. The younger brother Xuan Chen is established as the heir apparent of the Celestial Clan and is trapped in the strict rules of the Nine Heavenly Palaces.
When Ling Yuan was young, he met and fell in love with Wan Hua, the ancestor of the demon clan. However, the gods and demons took different paths. Wan Hua sacrificed his soul to protect the human race, leaving Ling Yuan alone to guard the mark of the remnant soul and spend tens of thousands of years in loneliness. Su Ling, the youngest daughter of the nine-tailed white fox in the Secret Land of Blue Fox, disliked the restraint of her clan, so she hid her fox body and took the name Lingyan, and went to Kunlun to become her disciple. Master and apprentice have been together for 70,000 years, and the vague feeling of being an old friend when they first met has long since turned into a deep love that belongs exclusively to Su Ling. Ling Yuan protects her in everything, hiding his love under the title of master and apprentice.
Heaven sent a love disaster, and Su Ling lost her immortal power and memory and fell into the mortal world, where she and Xuan Chen knew each other and stayed together. But after entering the heavenly palace, Jin Si, a woman from the heavenly clan, was trapped every step of the way. Xuan Chen repeatedly compromised for heaven's rules, causing her to suffer a lot. Su Ling, whose heart was filled with despair, stepped onto the Dust-breaking Platform alone, cut off all mortal ties, and regained her status as a god.
Xuan Chen was extremely remorseful and spent all his glory in heaven to save her, but it was hard to heal the scars all over her body. Su Ling resolutely let go of this wrong fate and looked back at Ling Yuan, who had never left her for 70,000 years. The two broke through the barrier between master and disciple and guarded Kunlun together.
The ancestor of the demon clan, Wan Hua, awakened from Nirvana, relieved to let go of the past, and stayed alone with the demon clan in the Southern Wilderness; Xuan Chen, sitting on the power of the Nine Heavens, was lonely all his life, leaving only endless regrets. The love and hate of three generations have come to an end, and the wrong fate has disappeared. Only the long-lasting protection can finally achieve a happy ending.
