In 2275 AD, humans captured an undecoded packet from deep space. It is not a greeting, but a "physical blueprint" beyond imagination. When trying to deconstruct this "gift" from the depths of the universe, he found that what he was facing was not the wisdom of alien civilization, but the most fundamental physical law of the universe - the law of conservation of information. Every successful interpretation means that humans are one step closer to a technology that can rewrite reality, and one step closer to the truth about the demise of the previous civilization. The real crisis never comes from the stars, but from knowledge itself.
