My name is Lin Feng. Yesterday I was discussing "business" with people in the dock warehouse. Today I have become a transfer student in Class 7 of Qingteng Middle School. The head teacher patted me on the shoulder and said, "Classmate Lin, you must study hard." I nodded and bowed, with an innocent look on my face. No one knows that there are bruises from yesterday's negotiation hidden under the cuffs of my shirt, and there are more than a dozen unread "Tangko Affairs Reports" on my phone. Until the second-generation rich man who didn't know how to live or die slapped the class fee on my desk in public: "Newcomer, this month's protection fee, do you understand the rules?" The whole class fell silent. I stood up slowly and suddenly smiled - no one had dared to talk to me like this for a long time.
