It tells the story of Feng Yuejiao, a poisoner and doctor, and the former prince Xiao Mingsong. In the huge conspiracy woven by Jinghong Tower, they uncover the interstellar truth spanning three thousand years. When ancient machinations collide with quantum technology, palace poison banquets intertwine with starship wars - the mountains and rivers are sealed with gene locks, the seven-star pattern is engraved with dimensional coordinates, and Jinghong Tower is actually an observation post for an alien civilization. The two used poisonous blood to rewrite the laws of life and death, used silver needles to sew the rifts in time and space, and fought their way through the tide of cloned avatars and mechanical Gu. From a war of words in the Golden Palace to glacier archeology, from living starships to anti-matter wedding rings, this poison-doctor showdown about the survival of civilization finally blooms at the edge of a black hole, a cosmic love that transcends life and death.
