China's first industrial fantasy novel in the field of industrial valves.
In 1980, barrel repairman Gu Dehou used a kerosene lamp to bake open a rusty valve. He drew "ghost symbols" on the account book that no one could understand, and wrote "Everything that passes by must leave traces." He firmly believes that iron can speak, water can sing, and flow has its own will.
Three generations, one hundred and twenty years. From the old lathe in the pigsty to the nuclear-grade valve that broke the foreign monopoly; from the earthen workshop by the Ou River to the fluid control system of the Mars base; from the intuition of the cooper to the awakening of AI, the uploading of consciousness, and the disappearance of valves from the universe...
This is not science fiction, but "industrial metaphysics" - every miracle has real industrial history as its backbone; every "understanding" hides the century-old bravery made in China.
When the valve no longer needs a valve, when the flow finds its own direction - the yellowed account book and the phrase "Flow, don't stop" are still ringing in the tide of the Dongou River.
Open it and you will hear the sound of iron.
