The Demon Queen's Royal Consort - Chapter 113 - Dungeon - XXI

Gabriel, a dominant omega, is caught up in a complex web of intrigue and danger at the royal court. After uncovering the truth about Olivier, a member of the royal family, and inciting a rebellion, he is marked by an unknown alpha. As the rebellion overthrows the old order, a new empire emerges, driven by a ruthless ruler whose rise Gabriel inadvertently enabled.Haunted by the weight of his actions, he flees from his family, his past, and the dangerous ties of the court. On the run, Gabriel must deal with shifting alliances, hidden enemies, and the growing power of the mysterious alpha whose mark he carries. As the empire's grip tightens and ghosts from his past resurface, he must decide whether to confront the forces threatening to engulf him—or risk losing himself completely in a world that regards him as either a pawn or a weapon.

"There is a thin line between poison and medicine, and I shall make you dance on it!"

Su Ran, a music prodigy, woke up transmigrated into a book.

At that point in time, the main story arc in the book had already been completed. As a villainess female supporting character, not only did she need to take over the original owner’s pitiful life in poverty, she also gained an instant son right at his rebellious period.

Ten or so more years from then, the son would turn into a twisted, evil villain. He would appear in one of the extra chapters to pick on the male and female lead’s children.

Su Ran: Son, you shouldn’t be too outstanding.
Su Han: Why not?
Su Ran: ’cause you will be killed.

Su Ran: Son, would you like to learn music from me and become a zen, little fairy boy who only needs to drink dew.
Su Han: No, I want to go into business so I can support you.
