Three hundred years ago, Demon Venerable Si Fanyin abducted Qingxiao Immortal Venerable Jun Ling to the Demon Realm. The two fell in love, and Si Fanyin and Jun Ling gave birth to three dragon eggs, becoming an absurd tale in the mouths of people across the world. The conflict between immortals and demons intensified, and the great war broke out once more. To quell the flames of war, Si Fanyin chose to let Jun Ling kill her with his own hands. Three hundred years later, the Demon Venerable returned. One son was raised by the immortal sects, one son was warped by the Demon Realm, and yet another was lost. Only then did Si Fanyin know that, for the three hundred years after her death, someone went mad, waiting for her to come home.
