I'll Change Your Sad History - Wheat Time Travel

My name is Huanmai, and I am a modern novelist. Because I had no inspiration for my new work, I asked a friend to go hiking together. During the process, I found a small cave. I decided to check it out out of curiosity. When I walked in, I found a portrait of a female general. It felt very familiar, so I touched the portrait. Then my eyes suddenly went dark. Almost all the memory scenes about the female general were played in my mind. However, when I woke up again, I realized that I had surpassed the female general, and it was the day before the tragedy in my memory was about to happen! Huanmai accidentally time travels to the female general, but can Huanmai successfully change the tragic history of the female general?
