Let's see what do we have here.
Firstly, the description -
I would suggest rewriting the description more fluently instead of abruptly jumping from telling about the first heir to another.
The heir of ABC is on his journey to regain his rights while the heir of XYZ is fighting for the independence of his fallen kingdom - instead of using one of them and the other.
Episode 1 - the first episode is the first impression for your series, so one must make sure to put extra effort into it, to grab the attention of the readers. The first episode was very small and the description of the surroundings, the appearance of characters and the way they talk is very limited. These things help to improve the reading experience. Try to increase the length of the chapters.
The grammar is weak and needs improvement. Don't worry you are not alone. I struggle a lot with grammar and description of the surrounding area and actions. Practice is the only thing that can help us.
Episode 2 -I liked the power setting and the names of the characters, but the flow of the story and the introduction of the characters is abrupt and can be improved. Working on the flow can truly help a lot, which is why I try to revise my chapters a few times before finalizing them.
I tried to give a short honest criticism. I hope these points can help you.
