@JPANIME I have to agree. We have no reference of exactly how much time had passed. Definitively, we know at least 20 years had gone by with Alto going on to become a successful adventurer before retiring back to his home village to raise a family and building the tree a new fence with his son. But in other panels, the fence is no longer there which adds more questions if something happened to them.
What about the merchant? Was the village Alto from purchased by him as well? If the tree is guarded around the clock, how did goblins set up a village at the base of the tree?
This is the one question that's bothering me the most. How did the guy not go crazy after all those years? He's trapped as a tree self-aware of the environment but can't move or communicate. Hopefully this manga has a LN which better explains all these strange plot points.
