I'm in Daqin, Did You Tell Me That School Starts?

After traveling to Daqin, I finally met Ying Zheng, but I received a text message notifying me that the school started?
I have seen Ying Zheng all the time, you told me that school started?
At this time, Ye Chen's system was turned on, directly constructing a time-space wormhole, and transporting Ying Zheng to the 21st century.
Facing the dumbfoundedness of the civil and military affairs of the Manchu Dynasty, Ye Chen had no choice but to enter the wormhole for self-protection, and returned to the modern age together with Ying Zheng.
Since then, Ying Zheng has opened the door to a new world.
"Ye Chen, why is this iron box running so fast?"
"What is this, and why is someone singing in it?"
"What is this, it's so delicious!"
"It's so nice here, I don't want to go back!"
Three months later, someone knocked on Ye Chen's door again: "Hello, I'm Li Shimin."
