Zhuge Liang was discussing with the generals to enter the army, when he suddenly reported that a Wei general had come to surrender. Zhuge Liang called him in and asked him, only to learn that it was Zheng Wen, a partial general of the State of Wei. Because Sima Yi made Qin Lang a former general, he did not receive a reward, so he was angry and came to serve.
Zheng Wen had just finished speaking, when he overheard a drum outside the camp, reporting that Wei would fight Qin Lang and name Zheng Wen to fight. Zhuge Liang asked Zheng Wen, "How is Qin Lang's martial arts better than yours?" Zheng Wen said, "I can cut him off at once!" ”
Zheng Wen happily got on the horse, and Zhuge Liang also took the generals out of the camp to watch the battle. Only to see that over there, Qin Lang slapped the horse and scolded; here, Zheng Wen slapped the horse and danced the knife to greet him.
Just after the confrontation, Zheng Wen slashed Qin Lang off the horse with one knife. Wei Bing also fled back.
When Zheng Wen returned, Zhuge Liang was already waiting in the tent. As soon as he saw Zheng Wen, he ordered the samurai to launch the beheading. Zheng Wen shouted loudly.
Zhuge Liang said, "I know Qin Lang, it wasn't him you just beheaded." Don't speak up honestly yet! Zheng Wen could not hide it, so he had to confess that Sima Yi had asked him to surrender, crying and begging for his life. Zhuge Liang said, "If you want to survive, you should quickly write a letter and ask Sima Yi to rob the camp." ”
Zheng Wen had no choice but to write a letter to Zhuge Liang. Zhuge Liang ordered him to be taken into custody temporarily.
