No More Weak People

My name is Lu Chengyu, I am 16 years old. I don't know what I have discovered in the world. Now there are only people under 18 years old in the world. There are no adults in the world. When the environment changes and the law cannot restrain and control human nature, then the human nature is dominated by evil people who do whatever they want? Or is the familiar warmth more desirable... Where will we, you, and them go in the end?
