Back from school, I'm going to the same place from yesterday, but this time the room to change, there was a door with a puzzle on the top legendary writing and a notebook written on it "Homosaka" it is the language it is written on the wall, I solved the message:

Solve the problem to access the 2nd temple.

To solve it, each line must consist of the same color.

3 colors are indicated: Blue-Red-Green.

I ended up cracking the code but it was late so I'm going home to bed

End of Chapter 3
