One day, an Internet cafe appeared in the Tang Dynasty. The administrator of the Internet cafe said: Governing a country cannot rely solely on reading, and fighting a war cannot rely solely on martial arts. You can also choose to play games.

So Cheng Yaojin, Wei Zheng, and Li Shimin all booked a night in an Internet cafe. As they played, they destroyed the Turks. As they played, they created a prosperous Tang Dynasty!
