This is just a small game, earn a little and run. You need to learn how to withdraw; you can't get stuck on it. Also, never be deceived by AI robots in places like squares that ask for money. Event contracts are not the same as contracts; there are no absolutes. It's better to figure things out for yourself. Don't follow my example of paying tuition and getting scammed like chives, although it's not much, it's still money.
