Rule Horror? But I'm an Immortal King

The Fairy King returns as a circus monkey. Jumping up and down performance

I saw Chapter 21. The most important thing when writing weird things is perfect logical and self-consistent rules. There are only 5 of the 6 rules here. Are they deliberately omitted? Didn't it say that the protagonist saw the hidden rules? Later in Chapter 22, he said "Another 6 rules" in the workshop, so it was obvious that Chapter 21 was talking about 6 rules, and one of them was omitted. This is even more perverted than the previous billboard with the keywords crossed out. For example: there is a rule that says "You cannot leave the room from 8 am to 8 pm." But it is not written out. The last one reads "Only one of the above rules is true." Then everyone must die, and no one can survive.

Let me just say that the protagonist is completely transparent.
