In Lin Yu's eyes, directly replacing the surveillance footage through "technical means" was a method that could be called "brilliant," but it also had major limitations in certain aspects.
The brilliance of this method lay in the fact that... it required no [Item] or supernatural system abilities. It could be accomplished solely through the technological means already available in the real world.
In other words, many people who were not "Players," as long as they possessed sufficiently advanced information technology, could temporarily block surveillance and loop a segment of footage to cover several minutes of recordings.
The brilliance of this particular method used by a non-"Player" was that it could perfectly conceal the user's identity.
After all...
Once someone used an [Item], used a gift from the "Death game," or used an ability from the Ten Realms, it would be easy to greatly narrow down the possible range of "Players" by identifying which realm the ability's effects came from.
But its limitation was...
This ability would also leave behind many flaws.
For example, at this very moment, the other party's method had exposed a new "key point."
Lin Yu stared solemnly at the surveillance footage of the corridor, then looked at Paper Kite. "So... you think the corridor directly below us at the same time might be where the real culprit or his accomplices were hiding?"
Paper Kite nodded and said, "Yes. Otherwise, there would have been no need for him to tamper with the surveillance here, right?"
"That's enough to show that... his concealment method actually isn't very brilliant."
Lin Yu watched the footage and nodded. "But I think there's another possibility... What if the person who modified the surveillance footage and the person who actually caused the tragedy and manipulated and altered your Memory weren't the same group?"
