Litography

A scroll of Mozi's fragments was unearthed in Tengzhou and was deemed a "false trust". The geometric propositions on it fit perfectly with the lens of a domestic EUV lithography machine that failed to pass inspection. Shen Zhaoye, a young optical engineer in the domestic lithography machine research team, received a call that his grandfather passed away after the lens adjustment failed. Returning to the old house in Tengzhou, I took down a scroll of insect-eaten bamboo slips from the beam. The first sentence, "When the scenery arrives, there will be an end at noon" is exactly the same as the data of his discarded mirror. This is no coincidence. This is the moment that the thirteen Light Keepers have been waiting for two thousand four hundred years. The lineage of craftsmen in the Mohist school did not write books or establish theories. They communicated from hand to heart, guarded the Mozi Engineering Atlas from generation to generation, and added in the fragments the technical prerequisites that could not be realized at the time, waiting for the technology to mature. From Tengzhou darkroom to Dutch bronze mirrors, from Weishan Lake underwater light tunnel to Hefei nuclear fusion device, from laser defense to drone swarms. Mozi optics, Luban wooden magpie, and Mohist city defense techniques are all resurrected one by one in contemporary science and technology. Shen Zhaoye faces more than just optical problems - the blockade by overseas giants, the infiltration of Guanghe, and the Chinese rival Gu Chengyuan who inherits his father's legacy. Gu Chengyuan only had half a page of pictures in his hands, and he had been chasing them for forty years. The source of the pictures was the Shen family. When the first wafer of a domestic lithography machine comes off the production line, it is engraved with the words "The scenery ends at noon". That light has been guarded for two thousand and four hundred years. Now, it is the turn of this generation to show it in the hands of every Chinese. Mozi and Luban came from Qilu together. Extreme ultraviolet light, magnetic confinement, directed energy, and swarming formations are all contemporary expressions of Moru's legacy. The spirit of Qilu is not in the classics, but in every beam of light that refuses to be extinguished.
