Starting from the Girl Reincarnated into the Magical World

After traveling through time, Si Bai found that he had turned into a silver-haired girl. That's nothing. The important thing is that this world is a magical world. If you tell me this, I won't be sleepy anymore. As he learned more about it, Si Bai found that the enemy this time... Seemed very familiar. There is also a female classmate who seems to be cheating around her all the time. This world does not seem to be simple. ~~~ It's a boring writing exercise, the plot is likely to be broken, there may be inconsistencies, and the characters may not match. Watch with caution at your own risk
