Start, Bind the Warring States Princess

The little protagonist is in a hazy dream. I was in a bad mood today and fell asleep while playing with my phone. But when I woke up and opened my eyes, I found myself in a different world. Unexpectedly, I had traveled through time. It's still a dream-like time travel, and there is system self-defense. Today, with the advancement of science and technology, it is common for people to travel through time, but the little protagonist is still underage now. This is how the legendary life of the little protagonist begins. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
