ZuluA After reading the first chapter I stopped to conclude several mistakes, this will be short as I have a bad (good) feeling where more people will be asking me to review their novels (Uh). First will be the usage of commas, first paragraph first sentence:
The Silver Horned [Qilin,] is said to be one of the most extraordinary, unique and of course rarest magical creatures in existence.
This issue persists throughout the first chapter which led me to point it out to be the tall tree. Several Phrases issues can be seen in the first chapter such as all that, you all, freaking, yeah, I don't, really, didn't, thing, got and don't. A problem with sentences too which is barely on the average limit (35 words) and mostly on being short sentences throughout the entire chapter. I have noticed that the narrative way is going south during the first chapter from how you addressed the characters and this is a huge issue if it continues during the next 100 chapters because people will judge you based on that itself and not how good your masterpiece is.
Vocab words are a bit of an issue here as you established a 10th grader wording system in your first chapter which is why I would recommend you to relate to this site:

Read it once and you should be good to go after going through my other points, keep up your great work and good luck!
