Ling Yue, a genius who cultivates immortality, cultivates the Supreme Path of Mercy. In order to ascend to the position of Immortal Lord, he needs to go through nine mortal tribulations, experience all the sufferings of the world with his mortal body, and discover the meaning of love.
In the reincarnation of heaven, his life chart is always entangled with a line of mortals - it is a thank you for being a mortal, without spiritual roots and destiny, but meeting him again and again. After eight encounters and eight life-and-death farewells, Ling Yue deliberately distanced himself, but was finally overcome by the sincerity and tenderness of his resignation. He watched his beloved return to dust, leaving himself alone to bear the pain of reincarnation.
In the ninth life, he transformed into the downcast orphan Shen Yan and lived in Lin'an. He met the Wenrun young master of the Xie family again and said goodbye. After staying together for three years, he tried his best to restrain his feelings, but when the Lin'an plague hit Xie Ci and he was in dire straits, he was willing to touch the heavenly punishment to protect him. The two broke through their inner defenses and worldliness and stayed together for fifty years, from young to gray-haired, and finally parted ways in life and death.
At the beginning of the ninth calamity, the memory of the eight previous lives awakened, and after being tempted again and again, he finally discovered that the ninth calamity was to uncover the love calamity and find the mortals who had been waiting for them all their lives.
Therefore, he no longer evaded, and crossed the reincarnation of immortality, just to allow him to live in peace and live up to the destiny of the nine worlds.
