An Elf Kid!

Zion once again got busy trying to act like an ordinary servant all day long. But this time, he had been secretly spying on almost every corner of the palace with keen eyes. While cleaning, if no one were looking at him, he would tap on the walls and ground to see if he could find a trap door. Then he would try moving the furniture and searching for a hidden door or something in the name of doing his servant's work.

But no matter how many times he searched the entire palace, he felt like he couldn't do it in one go. First, the castle was as big as an apartment building in his world. How would it be easy to do detective work undercover while pretending to be cleaning personnel simultaneously? But from what he had searched, he could tell that this was a time-consuming way to find the trap door where the murder scene could have taken place.
