In the era of deterrence, peace is a fragile facade. Genius scientist Luo Feng accidentally captured a mysterious echo from the Trisolaran First Fleet during an ultra-high-energy physics experiment, pointing to an ancient coordinate called "Era Recall." It is not a place of hope, but a huge testing ground for civilization, sealing the terrifying truth about the reincarnation of the universe.
Luo Feng and the retired captain of the "Bronze Age" Elena West formed an expedition team to go deep into this star field that even the Trisolarans regard as a restricted area. They discovered that the power of "era retrospection" can not only trace the past, but also preview the future - a cold future in which all civilizations will eventually become extinct.
At the same time, the Trisolaran Second Fleet was not far away, and an even older "Observer" civilization hidden behind the remnants of ETO gradually surfaced. The fates of humans and Trisolarans are once again intertwined, from two ends of a chain of suspicion to grasshoppers on the same rope. In this dark forest, there are always more than two real hunters...
