Welcome to the Threshold, where the laws of physics are child's play, and the only rule that holds is the rule of slaughter.
Ling Yi is a prodigy who can turn fear into cold logic, the sharpest blade of the secret organization known as the Retrospection Department. His battlefield is not the real world, but supernatural spaces where nightmares come true and the rules are twisted. His mission: solve the central mystery of each space, unravel its rules, and close the rifts.
Rules for survival:
Rule One: Force is useless. Intelligence comes first. (On the Evernight Train, running only makes death come faster.)
Rule Two: Observe the details and see through to the truth. (In the Silent Town, the movement of an eyeball points to the culprit.)
Rule Three: Solve the paradox to survive. (At the Mirror Abyss Art Museum, your sense of identity is a dead end.)
Hidden Rule: Every victory brings you one step closer to becoming something inhuman.
When his teammates become living specimens in the hospital's endless loop, and the frenzied audience in the opera house drowns out reason, Ling Yi discovers that these seemingly "natural" Thresholds bear traces of meticulous guidance by the "Weaver." Meanwhile, the Retrospection Department's secret experiments are pushing him toward the abyss of mutation.
Before madness devours his own logic, he must solve the greatest mystery of all: Who is the "Weaver"? Is the Retrospection Department humanity's savior, or the ultimate monster?
I got hooked right away from the beginning
