The Original God Became Ying's Licking Dog

Imaginary plot direction, another protagonist's journey to Teyvat, dark style, pseudo-villain. I am a ray of divine power set aside by heaven to take care of that little girl. It has been five hundred years, and I am about to wake up. By then I will be taken back by heaven and disappear from this world. No, whether it's for you or for myself, I must take you away from Sky Island. From now on, I will follow you wherever you are. What? Is this too licking? It should be domineering enough to master the power of the abyss, become the Lord of the Abyss, lead the seven gods to destroy the laws of heaven, and hand over the entire world to her, right? Maybe Tianli would never have thought that he would die in her own hands.
