Lost Adventure Notebook

Note

A set of adventurer's notes that you picked in the ruins. It seems to contain a clue to unlocking these mechanisms.

"Eric can't hold on any longer... We had no choice but to give up. I'll leave this notebook here. Maybe this treasure is destined for someone else.

As you may have noticed, the mechanism installed by the door needs someone operating it constantly. Otherwise, the other mechanisms cannot be operated.

But Eric physically can't take any more..."
