I Got the Heroine Pregnant from the Start, and the Neighboring Protagonist Is Green with Envy

[Villain + invincible from the start + more children, more blessings + feel-good power fantasy + ruthless and decisive + mastermind behind the scenes + taking what he wants by force]

Xu Xing transmigrates into a novel as a rich, handsome villain. The moment he opens his eyes, he sees the Dragon King smirking at him from the corner of his mouth.

After learning that the Dragon King will humiliate him later, Xu Xing says nothing and pulls out a pistol to shoot him.

The System warns him that he must first consume the protagonist's luck to kill him. “Quit your yammering! Are you telling me how to do my job?”

Terrified, the System immediately upgrades itself to version 2.0: it can now kill villains directly, and it also comes with a more children, more blessings System.

What? After he sends the Dragon King to prison, the Dragon King's senior sister comes to rescue him?

“Someone! Take the senior sister to the interrogation room next door.”

What? The Dragon King likes to disguise himself as a security guard to get close to the female lead?

“Then I'm spending the night here. You stand guard outside and do a good job!”
