Early on, when the pickings were slim, it was somewhat understandable that the likes of lesser lights in wulin such as Leung Tze Yung, Sa Tung Teen, and Pang Lin Fu would be of value to Prince Yeun Nan Hung Lit and Yeung Hong, but after Greats-level fighters such West Poison Au Yeung Fung and Kau Cheen Yan were enlisted by the Jin Empire, wouldn't those other guys have become redundant? What use would the Jin leaders have for the likes of Sa Tung Teen after gaining the services of Au Yeung Fung and Kau Cheen Yan?
And yet, despite their many bunglings and failures against the Jins' enemies, these guys were retained on the payroll of the Jin Empire until the bitter end.
