"Brother, save me——" The handwriting of the missing sister seeped out from a strange ancient book. The next second, Lin Ye, an old book restorer, fell into a death trap called the "Life-Weaving Corridor." Here, every world is a broken story, and failure will completely erase the existence; here, the "life-weaving fragments" that can strengthen oneself hide the obsession that devours personality; here, the prophecy of the mysterious man "Hourglass" and the secret of teammate Su Xiao all revolve around the whereabouts of his sister Lin Xi. When Lin Ye discovers that his sister is the creator of the Corridor and that her consciousness is scattered in various worlds, he must make a choice between "saving his sister" and "protecting the world" - and the true identity of "Hourglass" makes this redemption even more deadly.
