In the distant future when the solar system becomes two-dimensional, Cheng Xin and Guan Yifan piloted the "Halo" to the DX3906 galaxy to find Yun Tianming's last gift. What they discovered was not a habitable world, but an existence beyond comprehension - a "time loop". This device throws them into an endless drift: in countless universes where physical laws change randomly, they become eternal witnesses, watching the birth, struggle and death of countless civilizations under the law of entropy increase.
On a certain Earth-like planet, they met an artificial intelligence "messenger" created in the era of human escape, and learned about a hidden alliance: many civilizations on the verge of extinction are fighting against the heat death of the universe in their own ways. Cheng Xin was entrusted with the key fragment to find the "anti-entropy core" and embarked on a journey to connect messengers in different universes. She encountered messengers of various forms one after another, and was ruthlessly obliterated by the "immune system", the self-protection mechanism of the universe.
On the way, a friendly observer "scholar" who claimed to be from the advanced civilization "Tamipu" provided help, but under the calm there was an undercurrent. The road to find the key is full of traps and betrayals. Is the legendary "anti-entropy core" the fire of hope or the abyss of gravity? Cheng Xin gradually discovered that the ultimate gift Yun Tianming left for her was not the answer to salvation, but a more serious question: in the face of the doomed end, is witnessing itself the most profound resistance of life to nothingness?
This is an escape across dimensions and an inquiry into the essence of existence. In the shadow of the end of time, the final embrace is about to take place (continued by pure three-body fans)
