Angel pondered for a moment. What Tree Spirit said indeed made sense. If there truly is a hidden room within the ruins, and this room is quite special, Tizarro wouldn't neglect to mention it. Unless, there isn't anything inside the hidden room worth Tizarro's attention.
Of course, apart from this, there is another possibility.
Angel: "Perhaps Tizarro hasn't discovered this hidden room either?"
According to Tree Spirit, Lord Rhein has also searched the ruins and didn't find the hidden room, indicating that its concealment is highly effective.
Is Tizarro stronger than Rhein? Certainly not.
His belief that there is a hidden room in the ruins is purely based on logical thinking, inferring the habitual behavior of the ruins' creators.
He believed that an Alchemist, having all other experimental tools, couldn't be without a storage analysis table. So Tizarro speculated that perhaps the storage analysis table might be placed in a hidden room.
