In the past, he didn't dare to go down. Since the water is gone and he cannot fly, but things have changed, he can fly now and become stronger. Noah slowly flows down and reaches the end of this hole. Even though it's dark down here, it's not a problem for him since he has learned a technique that allows him to see in the dark.
After he activated his technique he Looked all around and got the first glimpse of the place where he was almost choked to death by a tree. But now there are no remains of the tree And the Only thing here is some skeleton he threw back then and black stone all over the place that he thinks of nothing.
Noah after that slowly flows out. From yesterday after he met that old man he is feeling somewhat empty, he is feeling down. That's why he decided to come here and to have a look if he feels better. But there are no changes within him.
