He woke up in a parallel time and space of the Song Dynasty: not the one in the history books.
The sea market here is like a tidal wave, and there are many foreign ships gathered here. The Shipping Department is in charge of the mails, the guilds are in charge of the positions, and the Transportation Department is responsible for the salt and taxes. The white people look at the regulations, and the underworld looks at the knife edge. Everything revolves around the "sea" - whoever can bring order to the sea is qualified to speak.
The protagonist Lin Yu breaks into this watery arena with memories of his past life:
He has no magical skills, only engineering brains and cold-blooded execution - to press the chaotic sea breeze into repeatable rules. Starting from fighting for a berth in the inner harbor, he wrote the emergency command of "block-press-spread-blow-collect" under the mast, recorded the "wind flower positioning and time period code" in the sketch, and took out the old equipment and reused it: fenders, pulleys, bellows, stop wedges, treads... The skills are put into the equipment, the equipment is used in the method, and the method is used.
The opponent was ruthless "Fang Qi" from the dock, and was carried all the way to Treasurer Xiaoxu, Transshipment Department Shangguan, and the Black Salt Line in the outer sea - he used the certificate chain to cover up the black talk, and used the system to win the fist; he leveraged the money bank and the lawsuit with the "travel date letter, the certificate draw point, and the sea consensus" to move from one branch to the sea step by step.
And she, Zhao Ruoxiu, the guild's female secretary, is as neat as a book and has a wrist as sharp as a knife. She and he stood side by side, looking at each other in the wind and salt spray. Can the hero of the sea, who takes all things black and white, and her, who sticks to the rules like a mountain, finally get married, or will they each stick to their own ways in the face of greater storms? The answer lies behind every tide.
