Entropy Lock: Civilization Relay

Physicist Lin Yuan discovered a set of signals in the cosmic microwave background radiation that are unlikely to occur naturally. It comes from the beginning of the universe and is older than the first stars. That same night, his wife Su Jin began to fall ill. It's not an ordinary disease—inflammation, allergies, insulin fluctuations, the symptoms are activated in turn like a switch. Around the world, the same cases are spreading at an exponential rate. The signal is decoded layer by layer, and the truth emerges piece by piece: The civilization of the previous universe cycle - the "ancestors" - discovered at the end of the increase in entropy that immortality and perfection are the poison of civilization. They created a race free from disease and death and then watched it fade into nothingness in eternity. So they designed humans. Chronic illness is textbook. Entropy increase is the ultimate test question. Every scientific breakthrough that humans make is an unconscious answer to this list that is engraved into genes. Those fleeting thoughts are the brain accidentally decoding forbidden truths, and are then deleted by the system as gibberish. And this legacy is in pieces. The heat death of the universe tore apart the ancestors' suicide notes at the last moment, and the fragments were scattered in the noise of background radiation, in the non-coding areas of DNA, and in all forgotten myths. The probability of successful reverse entropy is less than three thousandths. Humanity must choose: risk the entire civilization in an almost inevitable failure, or be like the ancestors and compress their entire civilization into a gift before the arrival of heat death and send it to the next universe. "They failed. So they created us. Will we succeed, or will we be the gods who create the next civilization."
