Douluo's Dragon Soul Sustenance

"Why, what did I do wrong, you have to leave me?" Gu Xu was desperate at this moment, kneeling next to the bodies of his parents, tears falling from his eyes. He hated himself for not having the strength to protect his parents. Dragon God: "Child, this is not your fault." An extremely majestic voice surrounded Gu Xu's ears, "Who are you? You did it to my parents..." "It's not me, it's God Shura. After he killed me, he stole a huge stone from this world. Unfortunately..." "Will you be my sponsor?" Gu Xu was confused when he heard this. Isn't Shura God a character in Douluo? What kind of sustenance does he have? But he still curiously asked "What is a sustenance person?" "I am you, you are me, and you are the second Dragon God. We are already dead in this world, so why not live in Douluo's world?" The Dragon God looked at the young man in front of him expectantly, "Okay, I do."
