[The cold and ascetic prince of the heaven x the madly criticizing world-weary demon witch] Zhao Yan, the sharpest blade in the heaven, lives his life in order, just to kill demons. Fang Yao, the last little ancestor of the Blood Demon Clan, wants to die and is afraid of chaos. In the battle between gods and demons, he pierced the heart with a sword, but struck out an ancient "Spell of Same Fate" - from then on, the skin on her fingertips was broken, and he felt pain like a knife; if she was seriously injured, he would kneel on the spot; what's more terrible is that without her, he lost all his cultivation and became a mortal; when he was close to her, his combat power exploded to the point of heaven. In order to protect the Three Realms (and her own life), the Flower of the High Mountains was forced to step down from the altar and hold this little ancestor who ruled heaven and earth in the palm of her hand. From being imprisoned in the Heavenly Palace to traveling together in Kyushu, from mortal enemies to co-masters of gods and demons.
