My name is Villian, an ordinary businessman. One day, I came into contact with a game because of an incident, but not long after I went out, a large truck suddenly rushed towards me, and I was actually cheated! ? But fortunately, I was lucky. I didn't die after being hit. When I woke up, I came to an unknown place, and then I realized that I had traveled through time. After time traveling, not only did I have two more sisters, but I also had a fiancée! ? This is bad. But that's not the worst part, but that I actually owe the system a huge sum of money because of a conflict with it? ! Poor me, I can only work as a teacher to pay off my debts while promoting the development of this backward era.
