An ordinary girl who is addicted to webcasting and has no ambition to make progress, travels back to the Anti-Japanese War period due to an accident. At first, the girl won the love of her teachers and the admiration of her classmates in the Anti-Japanese War school with her little cleverness and some historical materials she had read. Just when the girl was complacent about all this, the Japanese army attacked the Anti-Japanese War school and the instructor died. From then on, the girl became a different person, training hard and not daring to slack off at all. After graduation, the girl passed the examination and came to the general's side to follow him in all his expeditions. The general and the girl stayed together day and night, fell in love with each other, got married, and fought together in the war. Cannonballs are ruthless, and the world is righteous. The girl was infected by the comrades of that era and their beliefs. With the support of her love with the general, she truly put aside her personal interests, integrated herself into the life of that era, fought until she died, and returned to modern times. After the girl died, the general used his body to lure the enemy and was surrounded and suppressed. He died heroically and left a message before his death: Madam, you and I will be born in a peaceful era in the next life. I will love you well again.
