Princely Heir, please come back with us to the Prince Residence quickly.”Who knew, Little Baozi disdainfully said, “Not interested.”“Princely Heir, the Prince Residence is immensely wealthy...”“My mother is the wealthiest person!”“Princely Heir, the Prince Residence is extremely safe...”“My mother is the Martial Arts Alliance Hierarch!”“Princely Heir, the Prince Residence has powerful armies...”“My mother is the heir to the Nanduan Kingdom!”Suddenly, a faint voice came from behind: “Then, does your mother need an Imperial Consort? I think myself quite suitable.”
