Fang Zheng acted immediately upon uncovering the truth about Academy City. He was particularly displeased with this anti-scientific group that was both championing science and engaging in feudal superstition. Using the banner of science to promote superstition? You're bullying Newton, Einstein, and Galileo while they lie in coffins unable to come back to set things straight!

Fang Zheng wouldn't recklessly charge in to create trouble. Instead, he chose to establish his base within Academy City, as he still needed to chat and observe a few protagonists, right?
