Cao Cao disliked Zhu Ling, one of his generals, and had the intention of removing him from his position. He knew that Yu Jin had an intimidating presence so he ordered Yu Jin to take control of Zhu Ling's unit. Zhu Ling and his men did not dare to move when Yu Jin showed up at their camp and took over Zhu Ling's command. Zhu Ling then became Yu Jin's subordinate and all his men obediently submitted to Yu Jin's command. Such was Yu Jin's ability to strike fear into the hearts of others.
