Do Mental Exercise and Become a Logical King

With no progress in the investigation, Allen Boe does frog jumps in the second floor hallway to lift his spirits. It dawns on him that the number of frog jumps is wrong!

Yesterday, Allen Boe lost a game downstairs and was punished with 32 frog jumps from one end of the hall to the other. But just now he also jumped 32 times on the second floor. The second floor of the "Illusion Mansion" is clearly wider than the first floor and extends out a circle, so the distance should be longer and the number of frog jumps should be more...

Allen Boe realizes that there is a mezzanine on the second floor! He and Li Sidi investigate further and find more clues: a broken skirting in the first floor hall; "pipes" hidden in the skirting; a carpet that has been moved underneath the chandelier; and tulle fabrics hidden underneath the carpet...

The two detectives realize at the same time that the tulle fabric is spray-painted with the big skeleton from the "Skeleton Illusion Play"!
It seems that Aunt Miao Miao did not go crazy. On the contrary, someone deliberately sets up an "illusion" to scare her, and wants her to quit!
Although the giant spray-painted "skeleton" is found, the mystery still remains: Why did Miao Miao see the hall become the height of a two-story building? Only when the hall "grows taller" can the giant "skeleton" fabric be fully unfolded, but how can the hall "grow" on its own?

In order to investigate this strange building, Allen Boe secretly operates a drone to fly over the villa and take pictures of it. Now, the little detective has made an amazing discovery! The "Illusion Mansion" is not a two-story building at all!

In the end, Allen Boe catches the key clue to solve the mystery of the "Skeleton Illusion Play" in a bookcase in the theater professional book "Peeping Stage"...
