The Kong brothers are appointed as chief guardians of Liangshan's central camp after the 108 Stars came together in what is called the Grand Assembly. They are in effect the bodyguards of Lu Junyi, just like Lü Fang and Guo Sheng are to Song Jiang. Kong Ming participates in the campaigns against the Liao invaders and rebel forces in Song territory following amnesty from Emperor Huizong for Liangshan.
