After the independence of Korea, Yi ran away to South Korea to join with his gangster friend Yi Hwa-ryong's gangs of Myeongdong. After the Korean War broke out, Yi worked in the Headquarters of the Intelligence Detachment. In 1953, the political hoodlum Yi Jung-jae lured Yi out and lynched him, making him Yi disabled. Yi left the gangs, and escorted Chang Myon and Shin Ik-Hee from political hoodlums.
