Demon Child: From the Start, I Beat Up the Evil Longevity Peach!

[Multiverse adventure + light novel + The Birth of the Demon Child and the Havoc in the Sea + satisfying] So you're the Boundless Immortal Elder? What a nobody. If you're going to play dirty, you'd better have the strength and connections to back it up. Get it? Do you even know Nezha is my nephew? I slap you right across the face. Let's see if Yuanshi dares say a word! After roaming the Myriad Worlds all night, I finally arrived at the last dungeon in the Myriad Worlds. The Primordial World! I thought I was taking part in the Calamity of Investiture of the Gods, but it turned out I was only going through a dungeon based on The Birth of the Demon Child. Fine, fine. I was planning to steamroll everything anyway. But if I get to be Nezha's uncle... Heh. Nezha, step aside! Your uncle's going to carry! Facing the immortals of Yuxu, I slap the Deer Child once, then the Boundless Immortal Elder twice! When Yuanshi Tianzun tries to force my hand, I flash him a crooked smile. Aren't you the Demon Pill? Great! I'll give you a Demon King who wreaks havoc across the world! When the crowd questions whether Nezha is a demon... Ling Chen smiles and asks, “Anyone got a problem? If not, you can leave. If you do, I'll keep asking questions. Let's see whether I, the newcomer, know more, or you ordinary people do.” The whole point is to let off some steam from the movie. P.S. Some elements of the Primordial World setting will be included. The original is incredibly, incredibly, incredibly good, but the Primordial World setting works even better for a novel. Of course, the two will be blended.
