A three-year-old kid who starts time travel is about to be expelled from the family? Tang Jun, a double doctor in the 21st century, missed the mark and opened his eyes again to become a three-year-old boy in a small village on the border of the Great Yan Dynasty. He has no power to tie a chicken, but he unexpectedly awakens his extraordinary memory, and what he learned in his previous life turns into the capital to settle down. He wanted to develop his career in a low-key manner, but due to a false accusation, the aggressive villagers blocked his door. My grandma doesn't care about right and wrong. In order to protect the family's reputation as a "scholar", she actually uses cruel family methods on her grandson! Faced with the indifference and injustice of the clan's etiquette, his small body stood as tall as a pine tree. He used his wits to overcome the situation and exposed the truth in public, but he also completely saw the ugly face of the Tang family. With a decisive thought, he roared in public: "I, Tang Jun, have invited me to leave my clan!" From then on, he had nothing to do with the cold Tang family. A three-year-old boy with nothing to live up to and abandoned by his family, how will he find his own way to defy the odds and subvert the world in this strange and cruel ancient world?
