This is an era when knowledge is monopolized by theocracy. In the name of saving the world, the time travelers used modern technology to build a civilized cage. Seventeen-year-old Lu Ji, a waiter with the gift of photographic memory, resolutely embarked on the road of stealing fire after witnessing the lies behind the "miracle". He formed an underground alliance by joining forces with exiled old craftsmen, businessmen's daughters wandering in gray areas, and seminary rebels. Reverse engineering from rusted "ancient relics", exchanging forbidden knowledge in the black market of ideas, challenging unquestionable scriptures with reproducible experiments. This is not a war of swords, but an uprising of ideas - not only do they want to steal the sealed technological fire, but they also want to complete a god-killing debate on the altar where millions of people are staring. When the sharp edge of logic pierces the barrier of faith, will a civilization choose to continue to kneel down or walk into its own dawn with its head held high?
