The Regent Princess Consort Is Acting Up Again

The supreme quick transmigration god who rules over nine thousand great worlds transmigrates into a book, only to become a cannon-fodder woman who dies right at the beginning?! She marries the book's vicious, violent villain, and rumors say she won't survive the next day. Yet this unusually clingy villain not only survives, but sticks to her as if he's lost his mind. Even more incredible, there's already a two-month-old baby in her belly! Faced with one ruthless man after another shamelessly showing up to claim the child, including a regent prince, the young master of the Divine Pill Valley, a demon king from another world, and the demon emperor of the demon realm, who can tell her which one is the child's real father?! Wait, aren't these men supposed to be the female lead's lovers? Why are they all chasing after her, a mere cannon-fodder supporting character?
