Turning Into A Zombie

Throughout the video, he understood a few things. First, the Yu Chen of this world wasn't dead, but was ordered by the Emperor to get him killed. Second, he wasn't the only one to have panic attacks after learning of Yu Chen's deceit. The Xie Ai of this world also faced traces of severe depression for a few weeks before finally learning the truth.

That moment seemed to have broken him down and snapped a thread of sanity. After that moment, he hated everyone, including the world, the late Emperor, and especially himself. He wanted everyone and everything to die a painful death to relieve himself of the burden.
