The content of the story is about a group of teenagers fighting in a hail of bullets and crying in front of their brothers' graves for their own ideals, for the benefit of their motherland, and to prevent their beloved homeland from being bullied by foreigners. This book is also mildly obscene, never sexual, and the language is relaxed, because men have to watch life and death with a smile, so why be afraid if you are deeply involved in it! As long as the persistence in our hearts is still there, we will not fail!
