I can see it

after taking another look I thing the Author might have redid the story to make improvements and change some plot points it's not unheard of for a Author to put different drafts of a story under different name or release a earlier draft under a different name to get a feel for a reader's preferences so the author can release a later more perfect draft later. this insures that the overall quality is better in the final draft/story. it can also help a Author test out different ideas that are drifting in his/her head.

that's stronger from a sapling and its slightly different they have 3 legged crows and other divine beasts but the 2 novels are very similar they only have slight differences this one in particular is better because it gives the reader a better impression of starting weak and growing stronger than the other.

I love how the author used new concepts. the mc is more down to earth and has a lot of potential to grow and evolve. I like how he started out weak and slowly gets overpowered.

the system is perfect for the Harry Potter world. it's one of the best fanfiction that I have read. I like how the mc is more geared toward a supporting role instead of going down the typical overpowered attack route.

the story is interesting I like how the mc chose to keep his original race despite having the opportunity to choose a more powerful one the only complaint I have is in the first 3 chapters or missing and replaced with a another book.
