It was a boring math class, my best friend was sleeping, and I was peeking at crush. There was a sudden earthquake, the ground shook, and the whole class gave out. When I opened my eyes, I saw that I had traveled back in time to the concubine in the cold palace. At the beginning of the collapse of heaven, I actually awakened the modern system. After completing the task to attack the emperor and awakening the memories of every classmate in 435, I could return to the modern era. Unexpectedly, the emperor is my nemesis, the math class representative became my personal eunuch, my best friend traveled through time and became a rich woman, and the class teacher became a national teacher... Unexpectedly, they all lost their memory. Only by awakening the memory of everyone in Class 435 can we return to the modern age.
