Lu Junyi was fooled by Wu Yong when he went up the mountain. I guess Song Jiang took a fancy to Mr. Lu's wealth. He got him up the hill, and Song Jiang made way for him as soon as he got up the hill. Before Mr. Lu could say a good word, Wu Yong hinted that jy jumped out to kill people and then came out with Lu to scare him. Although Mr. Lu is new here, he has seen the world. This kind of political concept is understandable, so he quickly said what he is and what he can do. Wu Yong, a schemer, took advantage of the situation and said that it was not too late for Mr. Lu to rest in the wing when he first came, and he would make a difference in the future.
So Song Laosan was happy, and Wu Yong was simply a worm in his stomach. And Mr. Lu didn't dare to be the boss until he died. Apart from playing with sticks, he is actually a scholar at heart. He met bandits in Liangshan, where can he stand it and want to go with others? So, let him be the second child of Liangshan, and Song Jiang just stood on an empty shelf.
