Lu Yan, who appears to be an ordinary company employee, actually spends his spare time studying the secrets of ancestral Feng Shui and secretly investigating the truth about the family's decline. Appearing to be cheerful and easy-going, good at sociability (pretending), on the inside he is thoughtful and decisive in killing. He attaches great importance to his relatives and friends and is ruthless to his enemies. He believes in "Tit for tooth, repay tenfold".
