I recommend " The Genius Baby's Evil Mother ", an ancient romance novel. The main character is a modern female assassin who transmigrated into a useless woman. Later, she brought the cute baby back to Cheng Country. She was poisoned by bad people and was chased by assassins. She was rescued many times by the rich, handsome, and powerful domineering prince, but she had to marry him with her body and buy one for one. In front of others, the cold and overbearing demon prince was acting cute and coquettish to her, begging to take a bath together. I hope you like my recommendation.
