Seeing that many readers in the comments have some confusion, I've decided to write this separate chapter to explain things clearly.
First of all, the mythical bloodlines hidden within the protagonist's body are his true "cheat power"!
If it relied solely on the Bibilin Serpent Emperor, there's absolutely no way he could ever compete with the gods of the Divine Realm. Therefore, of course, the author has to give him some advantages—otherwise, it would just be too harsh on the main character.
What, should the protagonist really wait tens of thousands of years until his beast clone becomes a god? That would be absurd.
Some readers have asked: why not let the Bibilin Serpent Emperor transform into a dragon?
First, because the idea of a snake turning into a dragon is too overused—too many stories have done that. Secondly, the dragons in Douluo Dalu aren't all that impressive anyway. The highest-ranking dragon is the Dragon God, and he's just someone who was killed by the gods of the Divine Realm. What prestige can such a being really have?
Here, I need to clarify: in this novel, the Dragon God's setting is based on the lore from Douluo Dalu Parts 1, 2, and 3, as well as The Divine Realm Side Story.
The settings from Part 4 are too ridiculous, so this book does not adopt them.
According to the lore in Douluo Dalu Parts 1–3 and The Divine Realm Side Story, the Dragon God was originally a God King who ascended from the lower realms. Because he was oppressed by the other gods in the Divine Realm, he led a group of beast gods in rebellion—but ultimately failed. He was split in half by the Asura God's sword, becoming the Silver Dragon King and the Golden Dragon King.
And it was precisely because of the Dragon God's rebellion that the Divine Realm established the rule that no beasts may become gods.
The entire Douluo Dalu trilogy revolves around this setting. The conflict between beastkind and the Divine Realm is actually a well-designed and reasonable premise. Tang San's suppression of the soul beasts makes perfect sense—it's "politically correct," so to speak.
But then came Douluo Dalu 4, where the author completely overturned all that came before! He turned the Dragon God into a Creator God, even claiming that the entire Divine Realm was created by him. The beast race got an epic-level buff.
The most absurd part is that the rule forbidding soul beasts from becoming gods was rewritten to be a rule that the Dragon God himself made before dying.
Well, that changes everything—now all the blame falls squarely on the soul beasts. They become victims of their own doing, while the gods of the Divine Realm suddenly become pure and spotless, with no fault at all. Since it was the Dragon God's decree and not theirs, they're off the hook.
This kind of retcon was clearly made just to whitewash the Divine Realm—it's so exaggerated and illogical that it ruins the worldbuilding.
Therefore, in this book, I'm only using the settings from Parts 1–3 and The Divine Realm Side Story. The settings from Part 4 are completely excluded.
Now, about the protagonist: among the many mythical bloodlines in his body, aside from the currently awakened Nine Infants (Jiuying) bloodline, the others can basically be considered dormant or decorative for now. The awakening conditions are extremely harsh!
This is mainly because, after finishing the Douluo storyline, the story might move on to other worlds across the multiverse. By then, the other mythical bloodlines will come into play.
Of course, it's also possible that once Douluo is done, the story simply ends. That depends on how well it performs.
For now, just consider the other bloodlines as inactive. The Nine Infants bloodline alone is already enough for the protagonist to dominate the world of Douluo Dalu.
