Cao Cao led his troops to attack Zhang Lu and subdued Pound, the general of Zhang Lu. Song Yang accepted bribes from Cao Cao and proposed that the whole city surrender. Zhang Lu also surrendered to Cao Cao. Hefei defenders Zhang Liao, Li Dian and Qi Xin joined forces to defeat Sun Quan's attacking team in xiaoyaojin. Since then, Zhang Liao has exerted a great influence on Wu Dong.

Summary of Chapter 67 of Romance of the Three Kingdoms:

1, Cao Cao sent troops to the western expedition, and Zhang Lu sent people to retreat, which failed and lost several times. When Zhang Lu was anxious, Yan Pu recommended Pound to Zhang Lu. Pound was brave and good at fighting, and helped Zhang Lu repel enemy soldiers many times. Zhang Lu is very happy.

2. When Cao Cao saw that Pound was brave and wanted to take it for himself, he used Jia Xu's trick to make Pound surrender to himself. Zhang Lu finally defeated and surrendered, and Cao Cao pacified Hanzhong. Liu Bei heard that Cao Cao had taken Dongchuan, fearing that he would spy on his own Xichuan, so he used Kong Ming's trick to induce Sun Quan to send troops to attack Cao Cao.

After reading Chapter 67:

Cao Cao pacified Hanzhong, Zhang Liao and xiaoyaojin. After Cao Cao sent troops to copy Yang Ang and Yang Ren who were after Cao Bing, he took Yangpingguan and Nanzheng. Fuck, Pound Tokugawa. When people in Xichuan heard of the arrival of Cao Cao, they were all afraid. Zhuge Liang delivered the book and Sun Quan to the three counties of Jingzhou, Cao Cao led the troops to attack Hefei, and Cao Cao sent his troops into Xukou.

The capture of Hanzhong laid a good foundation for the next step into Shu. According to Hanzhong, you can either go out of Yangpingguan and take Jinniu Road into Chengdu Plain, or take Micang Road to attack Ba County in the east. At the same time, Wei Jun in Wudu area can also go south directly, without worrying about the threat of flanking Hanzhong area. Even if we don't launch an offensive, Guanzhong and Longyou of Wei will be well protected because of the barrier of Hanzhong and become the rear area of the battle.
