Dragon Clan: Lu Mingfei Doesn't Want to Be Defeated

Lu Mingfei was reborn not long after entering school. He was a 17-year-old student. None of this is important. What does it mean to be "reborn as the son-in-law of the Dragon King"? I'm just a bad boy. How can I be so virtuous and capable, brother? And what does it mean to "toughen one's will on the battlefield, so I'm on the Somme"? Thanks for the invitation, I was scared by machine guns and artillery. There is also this "I am a nephew going back to my aunt's house to spend the summer vacation during the summer vacation"! This is good... Hiss, no, no, no... Lu Mingfei, you have to be reserved... Also, who is this venomous little lolita who looks at me like I'm looking at trash every day and has a "favorability score: 100"! Looking at Chu Zihang holding the glowing Murasame and Caesar holding the interstellar rifle and shouting "onboard"... Lu Mingfei just wanted to ask: "System, the people and the world around me seem to be getting weirder and weirder. If this continues, I will be broken..." "Finally, didn't you agree that you would never be depressed? Isn't this wrong?"
