He’s the son of the Immortal Execution Archipelago’s Second Immortal, Zhan Jiuxiao and is one of the top geniuses of the Immortal Execution Archipelago. Although he may look young, he does things ruthlessly, doesn’t care what method he uses, and doesn’t care about the consequences.
He chases Chun Wu after she hears a secret about the activities of the Immortal Execution Archipelago and tries to kill her. Chu Feng appears and saves Chun Wu. In the fight with Chu Feng, Eggy uses her black flames to suck out almost all of Zhan Feng's source energy and crippling Zhan Feng's cultivation. Zhan Feng life is spared by Eggy and has an appearance of an old crippled man with no cultivation (Ch 765).
