Liu Tang gets wind of the conveyance of valuables to the Grand Tutor
Cai Jing in the imperial capital
Dongjing from
Daming. They are birthday gifts from Cai's son-in-law Grand Secretary Liang Shijie, the prefect of
Daming. Liu rushes to Dongxi village in
Yuncheng County to suggest to
Chao Gai, the village's headman who is well-known for chivalry, that they get together to hijack the valuables. Before he reaches Chao's home, he gets drunk and falls asleep in a rundown temple in the village.
Lei Heng, a chief constable of Yuncheng, comes to the temple that night while on patrol with his men. Lei is certain that Liu, with his odd and vagabond looks, is up to no good in the village. They pounce on him and tie him up before he could resist. They then stop by at Chao Gai's manor for some refreshment. Out of curiosity, Chao secretly goes to check on Liu, who is suspended in a side room. Liu tells Chao the purpose of his visit. Chao Gai then lies to Lei Heng that Liu Tang is his nephew, thus winning his release. However, feeling sore over the arrest, Liu catches up with Lei Heng as he returns to office and challenges him to a fight. Chao Gai comes to the scene and stops the clash. The hijack team eventually comprises seven men, namely Chai Gai,
Wu Yong,
Gongsun Sheng, Liu Tang and the three
Ruan brothers. Disguised as
date traders and with the help of
Bai Sheng, who imposes as a wine seller, they trick the escort party led by
Yang Zhi to take the drugged wine of Bai. When the escorts fall over numb in their limbs, the seven men cart away the valuables. But authorities soon track down essential clues and sends soldiers to seize Chao Gai at his house.
Song Jiang, a clerk of Yuncheng's magistrate, learns of the arrest order and rushes to alert Chao to flee. After beating their pursuers, Chao leads his gang to join the outlaw stronghold at
Liangshan Marsh. ==Joining Liangshan==
