A seemingly ordinary young man with a calm temperament is actually the heir to the secret technique of Feng Shui passed down from his family. He inherited his grandfather's compass (called "Xunlong Ruler" or "Celestial Star Compass") and a incomplete "Ley Lines Map". He is proficient in Luantou (topography), Liqi (directional luck) and Xingfa (sensing aura), but he pays more attention to the principle that "Feng Shui is the human heart" and does not use killing moves easily. He has a calm and introverted personality, is observant, principled, and does not seek fame and fortune, but he gets involved in turmoil in order to protect the peace of one party and explore family secrets.
