Capítulo 238: Awakening the Past 'Him'

Back then, there existed only Tier 1. One day, a person lost control, but he managed to defeat the Wisdom Parasite in him. It was then he pointed at the changes. Eventually down the line, we found the method to initiate a breakthrough. Though, we paid a heavy price to get that data."
