Lu Xiuyuan, a once-all-powerful special forces elite, chose to retire due to the heavy cost of a mission. He opened a small flower shop called "Silent Flower Language" in a corner of the bustling city, trying to heal his inner wounds with a peaceful life. He doesn't have a golden finger, but his years of life and death training have given him extraordinary [supersensory insight] - extreme sensitivity and analytical ability to small changes in the environment, subtle reactions of the human body, and even the smell left in the air.
However, the peaceful life was soon broken. Florists began to receive a large number of anonymous orders for specific flowers to be delivered to designated addresses. Lu Xiuyuan relied on [supersensory insight] to be keenly aware of the anomalies in these orders: the flower delivery addresses were all empty rooms, the flower combinations had hidden secrets, the flower delivery time was accurate to the second, and there was even a subtle special smell left on every order paper. He began to realize that these seemingly harmless flowers were actually "death invitations" for the international drug trade, and his flower shop had unintentionally become a "transit station" for drug lords to pass their codes!
