Ning Yechen used to be the Demon Lord. He singlehandedly took over the Demon Realm and attacked the Heavenly Realm. His name preceded him throughout the Six Realms. He got tired of fighting, so he quietly went into seclusion and became a happy hermit.One night, an Empress from the Heavenly Realm fell into the Mortal Realm after someone drugged her with an aphrodisiac. She inadvertently fell into his room, and they made out. After the deed, the Empress quietly left. Just when he thought he would never see her again, she showed up in front of him ten years later, bringing a child, saying it was his daughter and demanding accountability from him! “She’s your daughter. You have to be responsible for us!” Ning Yechen was stunned!

In the Kunlun Snow Palace, a sage once said, those who pass away wander, while the living cannot let go.Once the soul departs, it will wither like the autumn grass.Those who are reborn from the dead, existing apart from the mortal realm, shall be shunned by all celestial sects and smitten as undead demons.On this day, a youth awakens from within a coffin, his blood dry and his bones chilled, to find himself a century old upon opening his eyes.A single tear from a sage awaited, a constant companion, may unravel the dreams of the past.Seeking not immortality but a mundane death, not to lament with the ages over lost love and resentment, but only wishing to grow old with tenderness in this lifetime, beneath the white clouds that hold no envy for the heavenly realms.
