This is my first time writing. Please forgive me if it isn't very good. I'll do my best to fix anything that's wrong.
Modern girl Lin Youyou wakes up one day to find herself in the brutal era her elders used to talk about. Faced with a land ravaged by war and riddled with hardship, she does her best to take up arms, despite having been cherished by her family, and slowly grows into a formidable soldier. (The heroine isn't strong from the start. She is the kind of character who grows stronger through everyone's guidance.)
