Lin Jinglan, the head female escort of Longmen Escort Bureau, does not like red makeup but loves passwords. She improved the ancient "dart flag code", created an original "word splitting code", and even embedded special clay marks in the interlayer of porcelain, and invented the "cargo fingerprint technology". In order to build a safe and efficient logistics network, she created a "marine route latitude and longitude chart" based on "Army and Bei Zhi", using the first words of poems to convey top-secret routes, and also implemented a "risk hedging" strategy for dart distribution. Faced with the conspiracy of Jianghu to rob escorts, she united like-minded people to form the "Jianghu Escorts Alliance", used smart code warfare to resolve the crisis, and promoted the "Escort Route Safety Convention". This is a legendary journey of protecting trust, conveying feelings, and harvesting true love amidst the flashes of swords and secret codes.
