Lin Yuan, the infrastructure mad chief engineer who died suddenly on a construction site in his previous life, traveled through time and became a six-year-old orphan in Konoha Village in the Naruto world - to be precise, he was a Hashirama cell experiment subject of the "Root" organization. The day he climbed out of the training cabin, he had a whole knowledge base of human industrial civilization in his mind, and he also had the gift of being able to "see" chakra like engineering drawings. Danzo thought he had picked up an experimental subject, but he didn't know that he had picked up an ancestor. Three months later, Lin Yuan repaired the energy core of the "Root" base and escaped along the ventilation duct. He stood in the Sandaime Hokage's office at three o'clock in the morning and said: "I want to negotiate a business."
The mess that had been left unfinished for more than ten years during the post-war reconstruction of Konoha Village was turned into an assembly line operation in his hands. Earth Dun is used for 3D printing, Water Dun is used for high-pressure cutting, and Lei Dun is used for mining radar. Tailed beast? That's clean energy. While others were still using kunai and shurikens to solve problems, he had already used trade contracts and infrastructure networks to tie the five major countries into a chain of interests. The day the Otsutsuki clan arrived, they saw a ninja fortress that had completed industrialization, opened its shields, and pointed its guns at outer space.
"Our infrastructure," Lin Yuan said, "can not only change the world, but also reset the rules of the universe.
