Niu Jin

Niu Jin is an officer under Cao Ren. He was stationed in Nan Jun to defend against Zhou Yu and the Wu army. In one battle, he defied Cao Ren's orders and struck out of the castle, whereupon he was immediately surrounded by the Wu army. He was later rescued by Cao Ren, but Wei would lose the battle. Nan Jun was eventually taken by Zhao Yun.
