My Sister Crushed My Snake Eggs, and the Heirless Snake King Went Crazy.

In my last life, I was framed by my sister-in-law and became pregnant with the guard's child. She shouted "Eradicate the bastards" and beat me to death. After rebirth, I had a good pregnancy constitution and climbed into the bed of the Snake King. She was even pregnant with the child of the heirless Snake King, who was treated as a treasure and cared for. But my sister-in-law didn't know anything about it and still mistreated the fetus in my belly as a bastard and aborted it. She said, "How can a woman like you, who is neither good nor evil, marry the Snake King?" Little did she know that the Snake King in this life loves me to the core. I am the only woman who can be pregnant with his child.
