林冲
One day Lin Chong, instructor of the imperial guard, comes across Lu working out with his hefty staff and is amazed by his martial skill. They become sworn brothers. When Lin Chong is exiled to Cangzhou after being framed by Grand Marshal Gao Qiu, whose god son covets the instructor's wife, Lu secretly tails him and his two escorts. He rescues Lin when the two constables, bribed by Gao, are about to murder him in Wild Boar Forest. He is prevented from killing the two men by Lin, who says they are but small fries carrying out an order. Lu accompanies Lin all the way to Cangzhou. Before leaving Lin, he smashes down a tree with a single strike to warn the escorts not to do anything mischievous. He then returns to Dongjing.
