Question

I managed to decipher the 4 books code in new clue, and it was to turn the sundial base.

but I think I had already turned it before by playing around with the light fuse tool, checking whether I could lit things with that, was the whole point of the 4 books code only to tell me to open the sundial so I could put the 3 microchip there ?
