Lu Fang owns an estate on Hollow Island (陷空島), where he and his younger sworn brothers Han Zhang, Xu Qing, Jiang Ping, and Bai Yutang — collectively known as the "Five Rats" — are based. As their leader, Lu Fang is magnanimous, respectful, patriotic and heroic. He is also very protective over his sworn brothers, especially Bai Yutang, and can come off as sentimental or nagging at times. Lu Fang eventually becomes a Rank 6 Commandant (校尉) under Judge Bao.
