Feng Shui Martial Arts Legend

Xiaofeng grew up with his grandfather. After primary school, he went home to farm and grow vegetables with his grandfather. He usually followed his grandfather to read some strange words, draw some runes that he didn't understand, and practiced some martial arts. Year after year, Xiaofeng was eighteen years old. His elderly grandfather said that he would go out once and come back three years later. After his grandfather left home, Xiaofeng decided to visit the county town. Unexpectedly, what he usually learned from his grandfather came in handy and led him to a different life.
