Looking for the Light in the Long Night

(Not invincible + no golden finger + slow heat + oriental fantasy + time travel) Four hundred and sixty-three years of the Yan Dynasty. A man who has forgotten his original name wakes up from fear. He found himself a different person. Seventeen years old, his name is Zhang Zhibai. After his father died and his mother died, he had a younger sister who was about to get married and was working as an errand in the Nancheng Military and Horse Department. He remembered high-rise buildings, subways, and a woman calling him to eat. He didn't remember their faces, he just knew it was called "home." He wants to go back. So he practiced hard and wanted to become stronger. I thought I could find the answer by becoming stronger. He didn't know this road, and it would take him many years. I don't know that there is no home at the end of the road.
