The teachers and students of No. 1 Middle School in City Z never imagined that their peaceful campus life would be turned upside down by a group of "transfer students" : His Royal Highness the Crown Prince ate fried chicken for the first time and asked the aunt in the cafeteria if he wanted to join the palace and offer a sky-high salary. A painting by the second prince shocked the national master of traditional Chinese painting. The princess who conquered the country kept pace with the times and changed her Hanfu into a style comparable to that of big-name fashion brands. Shang Danpin, a mysterious general later broke the world record in the archery event of the school sports meeting, the son of a wealthy businessman from Jiangnan carried a box of gold to pay for class fees, and even the transfer student in the next class who always slept in seemed to have a shocking status in the world. At the mysterious altar at the back of the campus, a time and space chaos that spans a thousand years has caused the children of nobles who should have lived in ancient times more than a thousand years ago to collectively parachute into a modern high school. This group of transfer students with the genes of emperors and generals used the hard-core logic of the ancients to go crazy in monthly exams, art festivals and club recruitment.
After getting along for a while, the students discovered that these ancient classmates not only carried classical Chinese texts more fluently than rhymes, but also seemed to be secretly looking for their way home. With a mysterious letter from the Forbidden City, sudden changes in cultural relics in the school history museum, and the occasional worries about family and country expressed by transfer students, this chaotic campus life across time and space gradually reveals shocking secrets about the rise and fall of the two countries in time and space. Your noble Highness, the Crown Prince, has become your classmate. When the morning reading bell rings, you have to perform the courtesy of a monarch and his ministers. Students of No. 1 Middle School: Who will take care of these ancient bigwigs who change the school rules as an imperial edict? Wait, what did you say? A piece of silver in exchange for a breakfast. Your Highness, this old slave is here.
