Story:
The hero Lin Chong of Liangshan, seeing that Wang Lun could not tolerate Chao Gai and his seven sworn brothers, killed Wang Lun. Everyone then elected Chao Gai as their leader. Wu Yong became the military strategist, ranked second.
Lin Chong then recommended Gongsun Sheng to command the military, saying: "To defeat the enemy and achieve victory this time, who can match your excellent strategies, Master Gongsun? It is just like a tripod needing three legs; not a single one can be missing. You must not decline, Master Gongsun."
Gongsun Sheng was ranked third, and Lin Chong fourth.
