Datang: as the Prince, I Just Want to Be Ruined

He died suddenly while working overtime and became the crown prince of the Tang Dynasty, Li Chengqian. There is the fierce father Li Shimin, the emperor of the ages, and the second child, Mrs. Li, who secretly pokes and worries about his position all day long. In addition, the eternal mirror Wei Zheng chases and sprays... I worked as a cow and horse in my previous life, and I have become the top second generation in this life. You still want me to work as a cow and horse? Then I'm not here in vain! Let go of your inner morals and enjoy a messy life... By coincidence, Li Chengqian also got a lying-flat system. As long as he lies flat, he can exchange for various items, and even increase his physical fitness! Are you still standing like a hammer in the court every day? I'll do it right away!
