Nathan just played along. He couldn't help but come up with another idea the moment he knew about this person's identity.
Since the other party was a prince, he couldn't help but wonder how lawless he could be. For example, would he actually hit him here?
If not, then the grand library was directly managed by the empire or even the emperor himself.
To sully it was the same as giving up his right to the succession.
If he chose a different path, such as killing him outside this place, it would become a big clash between their sides. Obviously, Nathan wouldn't hesitate to use his new element if escape was necessary.
This might even be a perfect situation, especially if he became a fugitive. He could infiltrate even criminal organizations to figure out the Death Society.
At the very least, the Death Society wouldn't believe that someone who wanted to defeat them had become a fugitive.
