Mom, Hear My Thoughts and Go on a Killing Spree, While I Play the Good Baby and Drink My Milk

[Mind-reading + adorable baby + plot-driven power fantasy + reverse transmigration]

Shen Li's husband's family married her for her military achievements so they could seize her wealth after her death. They not only caused her elder brother's death, but also forced her to adopt her husband's illegitimate child, then killed everyone in her family and happily took all their wealth. The whole family went on to prosper with their mistress.

Nuannuan transmigrates from four years in the future and uses mind-reading in front of everyone to tell Shen Li:

[Mother, your husband has an illegitimate child. He wants to take everything you own after you die.]

[I'm really your child, but my father isn't your husband. He's your husband's younger imperial uncle.]

Shen Li promptly replaces the child she'd adopted with Nuannuan. Her husband's title is stripped, his mistress is killed, and Shen Li takes her mother-in-law down a peg and becomes the lady of the prince's residence.

Nuannuan then uses mind-reading to warn her younger imperial uncle:

[If you adopt your nephew's illegitimate child, they'll poison you and take all your wealth after you die. They'll feed your corpse to a dog, the dog will be poisoned too, and then flies will eat the dog's corpse, killing every last fly in the family...]

So, to prevent an entire fly family from dying, the younger imperial uncle chooses Nuannuan as his adopted daughter.

Now Nuannuan has both an adoptive mother and an adoptive father. Surely that counts as a happy family of three.

Watching the two of them, Nuannuan frets, her thoughts flying everywhere:

[When are Daddy and Mommy finally going to have me?]

That very day, the usually aloof and dignified younger imperial uncle pins Shen Li against the inside of the door, his eyes reddening as he murmurs, “Divorce him. I'll take care of everything.”

Outside, Shen Li's husband kneels on the ground, begging his wife to come home.

But then the younger imperial uncle, the man he had feared since childhood, leads Shen Li out by the hand and says coldly:

“Your younger imperial aunt's home is the Prince Regent's residence. If you dare frighten her or her daughter, not even the emperor can protect you.”
