My name is Lin Lin, and I am the only person who survived the so-called revenge for friends operation. Even my good friend Su Yuefeng, the planner of this operation, was not spared.

Looking back on this incident, a sentence comes to mind: "What is more terrifying than ghosts and gods is the human heart..."
