Guan Hu, affectionately called Brother Hu, is the second-in-command of the underground market operating in the capital. He is the man whom Lu Sinian accidentally saved from the Hong Xiu Zhang several years ago, an act of kindness that earned him Guan Hu's lasting gratitude and protection. Under Guan Hu's guidance, Lu Sinian and Wei Ping'an worked in the underground market for nearly five years, accumulating considerable wealth while maintaining false identities. Guan Hu has recently sent word that significant plans are being prepared and invited Lu Sinian to participate, but Lu Sinian has decided to completely leave the underground market. Lu Sinian also warned him about potential upcoming political movements, showing concern for his benefactor's safety.
