Dragon Clan, I Planted the World Tree

[No cp for all members + there may be character death + modification of the ending of the original character + the author's second creation + many surprises that may appear in the future + purely free + extremely slow to gain + atypical juvenile novel] The story begins with a dream. I dreamed that a leaf fell from a giant tree. (It's a self-exciting novel, it's very shocking, so it's best not to read it. If you're shocked after reading it, remember not to scold me)
