In order to protect the common people, Wu Wan, the god of war in the heaven, sealed his possessed lover Qingmu Xueyin with his own hands. This decision planted the seeds of entanglement between the two for three lifetimes. In the first life, he was a general who protected the common people, and she was a demon concubine who brought trouble to the world, and he used his life to wash away her sins; in the second life, he was a ruthless and desireless immortal brother, and she was an orphan in the mortal world who broke his Taoist heart, and was in love; in the third life, the memory awakened, and the truth emerged. They must face the source of the original "demon" together, make the final choice between love and the common people, and truly transcend the reincarnation of fate.
