I recommend the novel " Mad Concubine of Rebirth " to you. The main character, Lu Wange, died tragically because she was tortured by her step-sister in her previous life. She was accidentally reborn on the day of her wedding. This time, she vowed to avenge her previous life and not let down the man who loved her as much as his life. Rumor had it that King Yi was shrewd, cold, and bloodthirsty, but he only doted on Consort Yi. "Are you a dog?" Lu Wange looked at the black-bellied man and said angrily. The handsome man chuckled." I'll only be your dog." This novel meets your requirements. There are rebirth, modern times, underworld, and handsome and shrewd male leads. I hope you will like this fairy's recommendation.๐
