Sun Bin goes down the mountain to fight Pang Juan

Sun Bin is Guiguzi's apprentice. In order to get down the mountain, he fought a series of struggles with Guiguzi's other apprentices. Finally, Sun Bin used his wisdom to get down early. After coming down, Sun Bin served the King of Wei. He accepted the order of the King of Wei and trained a group of female soldiers. However, during the training process, they encountered obstacles. King Wei's beloved concubine and maid did not cooperate with Sun Bin's training. Sun Bin killed them both in order to establish his prestige. The king of Wei knew that Sun Bin had killed his beloved concubine. He was very angry and wanted to punish Sun Bin. Sun Bin responded to the king of Wei with two reasons: the general was out, the king's orders were not accepted, and the king had no joke. Unfortunately, the king of Wei did not punish him. At that time, Pang Juan was already doing well in the Wei state, but he was jealous of Sun Bin's talent and was afraid that Sun Bin would steal his limelight, so he set up a scheme to have Sun Bin's legs cut off. Later, Sun Bin and his other brothers used the formations left by Gui Guzi to defeat Pang Juan. Pang Juan, who escaped, fell into the trap he set by mistake again. In the end, Pang Juan suffered the consequences and was shot to death by his own archers, fulfilling his vow to be willing to suffer arrows piercing his heart if he violated his oath.
