Because Lin Yu had experienced too many similar situations and even possessed abilities related to them, he knew very well that "interference" targeting memory and cognition came in many different forms.
As he continued to feel this "Oblivion" activate again and again, Lin Yu noticed...
This power originating from an Authority felt very similar to those things Old Zheng had set up around the asylum back then.
It could even be said that they shared the same origin and nature—only compared to Old Zheng's arrangement, this "Oblivion" occurred more frequently and had fewer restrictions.

At this point, Old Zheng's thoughts suddenly became sluggish.
