My Princess from Another World in Time Travel

On a rainy day, I understood the consequences of playing online games. That is - time travel. However, I was not prepared. I didn't bring a flashlight, a lighter, a camera or a history book. It turns out that even if I brought it, it would be useless, because this is a dynasty I didn't know - the Blood Moon Kingdom. This novel and its characters are purely fictitious.
