The disaster foreseen long ago is an hourglass that could overturn at any moment.
He Lan and Mo Sijin are about to leave for field training when, just before departure, they receive a request from Song Ying: find a missing project director from the Guanghe Group. She possesses cutting-edge technology capable of reshaping the human body. The scholar Song Ying calls the "god-servant" may be the key to helping He Lan turn the hourglass around!
He Lan and Mo Sijin set out with a mixture of unease and hope. Little do they know that before their journey even begins, they will step straight into the Featherkin's territory. With old grudges and new enmities converging, the two are forced to travel with Wu Ting. As their investigation deepens, they uncover a chilling truth at the project base where the "god-servant" went missing. Along the way, they encounter a girl who can glimpse death, a young woman who exists only in consciousness, a boy who can cleave through time, a monster with an immortal body, and humans who call themselves experimental subjects... Countless pieces of information from the past and present are linked together.
Time turns endlessly, life comes and goes, and the experimental ground known as "Paradise" endures forever. Humanity once reached a boundary that even the divine race had never touched. Now that the past is being unearthed once more, the fallen divine race will bury the "truth" beneath a raging fire that consumes everything...
