Fear

"Yes, as you see, they have many branches. We can just cut them off, or better yet, a few twigs."

"Shiro, that tree may have some small twigs, but it's so high that it can easily reach five floors. 

To get this, you need to climb it first. Have you looked at the picture when it has a real person on it?"

The tree looked like a towering tower that became smaller the higher it went. 

To get the small twigs, just like Suiyin said, he needed to climb it all the way to the top.

Rafael then looked for a pic with a person for comparison, "It seems I was too fast in coming to a conclusion. Maybe I should just look for another tree."

"It's useless, Shiro. I have looked; other trees exist, but none grow near this city. It's not like we can fly over the sea just to get one."

Rafael put some thought into it and then said, "Maybe I will just ask for help from Aurora then. It's a forest anyway, who knows what kind of beasts we will meet there."
