Passionate: Upgrading Weapons, I Fight on the Frontier for the Motherland

Enemy countries are watching with eager eyes, but they are still determined to destroy us. A passionate man with a burning heart to serve the country... The system said: "Host: You should first put down your posture and become a low-key researcher." Li Feiyang said angrily: "The enemy has put a shit basin on their head, and they are still doing nothing! And they are so low-key!" The system said: "If you don't keep a low profile, you can't do research, and if you don't pretend to do research, you won't have the chance to use the weapons I provide you." Li Feiyang seemed to understand something and said: "Oh, that's it. Then keep a low profile. Isn't it okay to pretend to be a low profile? Then pretend to do research." ………… The system said again: "Host, you should endure a few beatings. If you kill all the enemies in a few strokes, you will have no chance to stay in the army!" Li Feiyang thought for a while and said stupidly: "You have to be patient. If you make too many contributions and rise in military rank too quickly, you will attract everyone's envy, jealousy and hatred!" This novel and its characters are purely fictitious.
