Cao Yuan, a severely autistic genius boy, was regarded by the villagers as a "little mute" who could only tinker. His only two hobbies are counting ants and banging rusty iron nails on scrap iron plates. No one knew that the iron pattern he knocked out at random was the core structure of the "Thousand Machine Lock" that had been lost for hundreds of years; the fixed iron hoop he put on the old locust tree at the entrance of the village happened to seal the deflation point of the earth's veins. Until one day, an antique boss from the provincial capital came to the village with a team of "treasure appraisal experts" to "pick up leaks" and pointed at the iron shed under the old locust tree and laughed at "waste utilization". Cao Yuan raised his head and tapped out a piece of Morse code with an iron sheet, which read: "The 'Jade Seal' in your hand was imitated last week." The boss didn't believe it and identified it on the spot as a fake. The whole place was in an uproar. At this time, an old man wearing a military coat walked out of the crowd and stared at the seemingly useless knock marks on Cao Yuan's iron shed. He was so excited that he burst into tears: "This is... The inheritor of the 'Thousand Machines and One Line'?!" From this moment on, the originally peaceful small village began to surge with undercurrents. The antique circle, the military, underground forces, hidden families... All eyes are focused here. Cao Yuan, on the other hand, just silently picked up a new piece of iron sheet and continued to hammer it. He doesn't care who these people are, he only cares whether the next "thing" to be built will be more interesting than the last one.
