I Just Want to Make a Minimum Salary, so I Teach Poor Students to Become Gangsters

[Urban imagination + funny and relaxed + sinister + pretending to be a pig and eating a tiger + system + time travel + high martial arts] Lu Chen traveled through time and became the illegitimate son of the richest man whose superpowers were abolished. In order to protect himself, he came to the worst "Ninth College" in the country to work as a fringe tutor. As long as he is legally expelled from school, he can fully inherit the tens of billions of trust funds left by his mother and become a rich man. In order to quickly screw up the work and get money to run away, Lu Chen, who bound to the [Villain Mentor System], decided to lead this group of losers on an evil path and go crazy to death! In practical combat classes, while others teach fighting, he teaches students to "spread lime, kick the crotch, and set up serial traps." In psychology class, others teach truth, goodness and beauty, but he teaches students "how to use psychological suggestions to make the opponent's heart collapse." Lu Chen was filled with joy as he waited for his students to cause serious trouble and be expelled. As a result, in the national league, the students he brought out did not respect martial ethics, madly poisoned, beat sap, and tortured the top geniuses to doubt their lives, and they became the legend of the entire army! The top management was shocked. Not only did they not fire him, but they put all the most dangerous second-generation chaebols in the country into his class! A few years later, the richest man felt guilty and brought his bodyguard to take his "tortured" good-for-nothing son home. But he was shocked to find that the King of the Night who monopolized the global underground black market, the border Shura who killed the aliens so that they dared not cross the border, and the plutocratic oligarchs who controlled the global economy... Were lining up outside Lu Chen's door, shouting respectfully: "Teacher, you have tea." The richest man's legs went weak: "I asked you to take refuge in school, and you taught a ruling group with all evil people?!"
