In Magistrate of Zhongmou, when Cao Cao failed in his attempt to assassinate Dong Zhuo, he was labeled a wanted man and a man hunt was issued. Cao Cao tried to flee back to his home country, Qiao, but he was caught by the guards at Zhongmou and recognized by Chen Gong. The magistrate, in search of a worthy and just lord, privately interrogated the fugitive at night and asked Cao Cao's reason for going against the Prime Minister. Once Cao Cao responded that he wanted to remove the source of evil from the state, Chen Gong released his prisoner's bonds and agreed to follow the fugitive. He stated that his aged mother and family lived in Dongjun before they made haste to travel to Qiao.
After three days of traveling, they arrived at a farm run by the sworn brother of Cao Cao's father, Lu Boshe. Although welcomed with open arms, Cao Cao doubted his uncle's sincerity and became paranoid for their safety. Lu Boshe excused himself to fetch good wine for his nephew and the travelers waited at the straw hut. They heard a sharpening knife and words of binding before killing. Suspicious of an ambush and deception, they quickly killed the eight people within the home, but were startled to see that they had only meant to slay a pig for a feast. The wanted men rode on horseback, running into Lu Boshe on the road. To spare his uncle the sight of his own family dead, Cao Cao cut him down. Frightened by his comrade purposely killing someone and spreading more guilt to his conscious, Chen Gong tried to reason with Cao Cao but was only met with contempt. Whilst resting in an inn that night, Chen Gong thought about killing Cao Cao. However, he reflected on his actions and didn't want to be called a villain for going back on his original intentions. Therefore, he left without saying goodbye and rode back to his home.
Chen Gong is later mentioned in chapter 10 as a minister for Tao Qian. As Cao Cao was in the midst of conquering the latter, Chen Gong was granted an audience with his former friend. Although he already knew his answer to the negotiation, Cao Cao saw him since he couldn't forget the kindness Chen Gong once showed him. Chen Gong tried to emphasize Tao Qian's good qualities and asked Cao Cao to abandon his revenge for his family's death. Cao Cao still harbored anger at Chen Gong for abandoning him and refused. His mission failed, Chen Gong couldn't face the thought of Tao Qian's disappointment and rode away to serve under Zhang Miao. He later convinced Zhang Miao to join Lu Bu and became Lu Bu's strategist.
As Lu Bu's strategist, he was very skilled and the one that Lu Bu called for the most. Lu Bu listened to each of his plans thoroughly at first, agreeing to carry out most of them. Chen Gong suggested going to Xiaopei and assured Liu Bei that they would be good guests. He supported the plan to capture Xuzhou and accompanied Lu Bu with Gao Shun. He also advised to keep relations high with Yuan Shu yet gravely disapproved the marriage alliance with Lu Bu's daughter. When Liu Bei offered peace relations, Chen Gong advised to refuse since Lu Bu would have benefited more with Liu Bei gone. When the troops began to lose faith in their lord, he regretted the turn of events but continued to be beside Lu Bu. As with their historical counterparts, Lu Bu considered Cao Cao's offer to surrender but Chen Gong refused. His refusal was much more daring as Chen Gong shouted directly at Cao Cao and shot an arrow that took out the plume of his target's helmet. An infuriated Cao Cao answered with a death threat on Chen Gong's life. With reasons similar to history, Lu Bu ignored Chen Gong's council for the rest of the conflict.
When Xia Pi fell, Chen Gong was captured by Xu Huang. He shared spiteful words regarding his thoughts about Cao Cao's wickedness and again blamed Lu Bu for their defeat. He died a similar death as his historical account, except that his death moved every observer present. His mother, wife, and children were immediately ordered to be given hospitality at Xuchang.
