Arknights, but It's an RTS

[Classic orphan template + System + no heroine (the author has no idea how to write one) + lighthearted + little boy]

Ling He, a downcast young man, accidentally transmigrates to this suffering land and also happens to acquire a rather broken System. What kind of story will he write on “this land”? Let's wait and see.

This is the author's debut novel, and it's my first time writing fiction, so there may be plenty of things you don't like. I hope you'll tell me what they are. Love you all!
