If You Are Asked to Be a Teacher, All Your Students Will Be the Emperors of the Ages?

Li Changan traveled through time and was bound to a teacher-student system. He thought he would be able to reach the pinnacle of his life, but he found himself trapped in the mountain and was told by the system that he could only leave the mountain by accepting disciples. Looking at the deserted mountains, Li Changan felt helpless and didn't know where to look for students. Until one day, an old man named Zhu Shiliu broke into Li Changan's courtyard and accidentally became his student. Gradually, there are always more people in the small courtyard, and their names are also very strange. What about Liu Azhu, Li**, Cao's wife, Liu*shoes, etc. Li Changan lamented that they were all children from poor families! That's great! I will teach you the art of slaying dragons as a master, and kill those foolish emperors like Emperor Qin, Han Wu, Emperor Zong and Mingzu of Tang! Li Er: "Sir, how is Li Shimin?" Li Changan: "You are a fool!" Zhu Shiliu: "Sir, what about Emperor Hongwu?" Li Changan: "He is also a fool!" Qin Zheng: "Then the First Emperor..." Li Changan: "He is the ancestor of the Hunjun!"
