After ten years of undercover work, I personally destroyed the largest drug trafficking syndicate in Southeast Asia and returned with scars all over my body. The phrase "the nightingale returns to its nest" was met with cold denial from the boss. In the system, I had already "died in the line of duty", all mission records disappeared out of thin air, and my former comrades died and scattered. I was treated like a psycho, a drug dealer, and was in dire straits. An unexpectedly discovered chip and a reporter suddenly appeared, tearing apart ten years of secrets. I worked step by step and finally uncovered the covered undercover file, only to find that my boss was just a pawn and the real black hand was hidden deep in the system. After ten years of drinking ice, it is difficult to cool down the hot blood. The nightingale will eventually return to its nest, and the injustice must be redressed.
