Yu Baosi - Joining Liangshan

Joining Liangshan

Duan Jingzhu brings 200 fine horses from the north and the famous "Jade Lion" steed, intending to present it to Chao Gai, chief of the outlaw band at Liangshan Marsh. Yu Baosi and his men rob the horses and present them to the Zeng Family Fortress. The Zengs hurl abusive remarks at Liangshan and anger Chao Gai, who personally leads the outlaws to attack the fortress. He is killed in the battle by a poisoned arrow from Shi Wengong.

Song Jiang succeeds Chao Gai as chief of Liangshan and he leads the outlaws to attack the fortress again. The Zengs lose a few battles and two of the five Zeng brothers are killed in action. The Zeng patriarch, Zeng Nong, decides to come a truce with Liangshan and Song Jiang names his conditions; hand over Shi Wengong and Yu Baosi and the horses. Zeng Nong returns all the horses except the "Jade Lion" and he refuses to hand over Shi Wengong to the outlaws. The outlaws receive news of imperial forces approaching from Qingzhou and Lingzhou and decide to halt their attack on the fortress temporarily.

Song Jiang succeeds in persuading Yu Baosi to join Liangshan and he implants Yu as a spy in the fortress. Yu Baosi helps the outlaws capture the fortress and Shi Wengong. When the outlaws attack Dongping Prefecture, they send Yu Baosi and Wang Dingliu as envoys to announce the attack to the prefect. Dong Ping suggests to the prefect to kill the envoys, but the prefect ignores him. Wang Dingliu and Yu Baosi are beaten and driven out of the city. The outlaws succeed in capturing the city eventually.
