Revenge of the Demon-Suppression Guardian — Episode 20

Heo Chi-su, embodiment of Earth's will, reached Martial God state at age ten. He guarded the Demon-Suppression Pass for 30 years, slaughtering demons and maintaining peace. The Federation, believing demons benevolent, exiled him for his immense influence. Once gone, demons massacred the population. Too late, the Federation realized their mistake. After humans were enslaved, the demons challenged Heo Chi-su, only to be wiped out in a single blow.
