Some say that they are here to save mankind, some say that men are not good, and some say that they want millet and rifle to fight against the Free Empire... Qin Mu felt very troubled by these naughty children. However, he didn't know that these elementary school students in his eyes were actually Cao Cao, Valkyrie, Xiaoqing, Pinghe, Uchiha Madara... Originally they thought Qin Mu was just an ordinary person, but after listening to his lectures, they actually acquired the system. "Ding! Congratulations to Cao Cao for obtaining the artillery manufacturing technology. If you continue to listen to the lecture, you can obtain the steam engine manufacturing method." "Ding! Congratulations to Brynhildr for getting three summoning points. If you continue to listen to the lecture, you can get more summoning points." "Ding!
