The Battle of Ru Nan was a battle between Cao Cao and Liu Bei.

Dynasty Warriors
In Dynasty Warriors 4, this acts as a 'Tales' level for Shu. Liu Bei is suddenly attacked by Cao Cao after leaving Yuan Shao at Ru Nan Castle. Zhao Yun arrives to serve under Liu Bei just in time to save him from attacking Cao Wei troops. Guan Yu also arrives at the other side of the map after fleeing from Cao Cao. The only way to get out of the castle to attack Cao Cao is by defeating Xu Zhu in the center of the castle. Then, Xiahou Dun arrives at the northern exit of the castle. After defeating him, you can advance north to defeat Cao Cao and escape.
