I Married the Crown Princess from the Start, and Father Emperor Wants Me to Fill the Palace

After transmigrating into the Great Yuan Dynasty as the ninth prince, Qin Heng had hoped to live a carefree life. But the Crown Prince set him up, trapping him alone with Chu Qingcheng, the Crown Prince's future bride, and caught them in the act!

Just as he is about to be thrown into the death-row prison, his sign-in System awakens! But his newbie gift is a "Virility Pill"?

With his back against the wall, Qin Heng gets creative. In front of the entire court, he pulls out a divine pill and starts making wild claims: "Father! I've awakened the More Children, More Blessings System, bestowed upon me by an immortal! This is an elixir!"

The old emperor, who has struggled to have heirs, swallows the pill and is instantly amazed. Overjoyed, he declares on the spot: "Heaven bless Great Yuan! I hereby grant the Crown Prince's future bride to Ninth Brother! The treasury will pay for a grand wedding!"

The Crown Prince is furious enough to spit blood. I set a trap to hurt you, and not only did you steal my bride, Father is throwing in a dowry too?!

From then on, Great Yuan takes a wild turn.

The villains try to send a female assassin to ambush him? Qin Heng welcomes her with open arms. "Father, this assassin has the face of a woman who brings her husband good fortune!"

The emperor waves his brush: "Arrange the marriage! Anyone who dares stop Ninth Brother from having heirs is committing treason!"

On the surface, Qin Heng indulges in beauty under the pretext of his "heaven-ordained destiny to have children." In secret, he uses the sign-in System to recruit invincible iron cavalry and peerless generals.

When the Crown Prince leads an army to seize the throne, brimming with confidence, Qin Heng's million-strong army crushes his forces into the dirt.

Qin Heng spreads his hands helplessly. "Eldest Brother, all I wanted was to be useless. You're the ones who forced me to become invincible!"
