There are some grammatical mistakes here, and a few things I have to complain about. But I do like many things about your writing. It's easy to follow, and I can tell you put a bunch of work into it. That being said there are many grammatical errors, and a few format errors. Not to mention, that there are exposition dumps a few times in quotes.
leaving them no respite and making them feel a sense of despair every second that they struggling (struggled) to survive. This is an incorrect usage of tense.
"Sigh, this will never end..." I do not like things like this. It makes him seem like he is literally saying "sigh", rather than sighing. It would be better to put something like: He sighed, "this will never end." Or even: "This will never end," he said, sighing. There is another example in the chapter as well.
"Sigh, it's been six months since these nightmares started, and I still don't understand it." It would even be acceptable to put *sigh* instead if you want to use this format. The asterisk are important to show he is sighing, and not saying "sigh".
Another thing to complain about is repetitive language:
beasts, different species, etc. Those things are repeated a lot.
Now is for the format errors:
"You should avoid wasting so much crystal essence for such weak crystal beasts." said the young man. "If the worst happens, I will die fighting." said the young woman with a firm tone. Both of these are bad examples of dialogue tags. "You should avoid wasting so much crystal essence for such weak crystal beasts
," the young man said (or said the young man, but with a comma not a period). The same thing applies for the second quote (," said the young woman or ,"the young woman said).
I wanted to give 4
because I actually enjoyed it, despite the many errors, but I cannot in good faith due to the few exposition dumpy quotes. I am just going to post three of them in this section.
"Still, even with the power I have in this dream that can kill thousands of crystal beasts just by waving my hand, I can't do anything against this dragon that always appears as a divine existence. Does such a monster really exist in this world...?"
"Not to mention this woman... Her face is blurry. I can't even make out the slightest detail about her, but every time I see her in my nightmares, my heart can't calm down, and every time the claw of the dragon pierces her, my heart tightens as if it will break into pieces."
"After several years of negotiations, the peace treaty between the Aegis Alliance and the Elves of Loania is about to be signed. Agreements allowing exchanges between the two species will be put in place in the following month..."
This is too much. You are giving the reader way too much information in these passages. The third one, for example, can just happen naturally in the story without appearing on the TV.
Appeal: (2/5)
This has decent appeal to the SH audience, and the results already show that. Though the first chapter is a bit wordy to hook in more readers in my opinion. You can give the exact same story in the first chapter with no different meaning in way less words. What I mean to say is "concision". Cut many of the exposition dumps, and extra words that aren't necessary.
Conclusion
Pretty solid writing even with the grammar errors. It's an interesting premise too, but you have to fix the exposition dumps, repeated words, and format errors.
