During a delivery trip, courier Lu Chen discovered that his body was undergoing irreversible "fusion" - blood vessel lines were brightening and disappearing, his perception extended to the gaps between dimensions, and he was synchronizing with the city's abnormal resonance.
He thought he was the only outlier, and he didn't understand the truth until he met Zhou Ming, who had also been transformed, and received a lacquered envelope left by Zhou Qiming, who disappeared ten years ago:
Three hundred "anchor points" are scattered throughout the city, maintaining the barrier between reality and other dimensions. Barriers are coming loose and cities are crumbling. And he is the only "key" that can sense the anchor point and repair the cracks.
But the price of repair is becoming the anchor itself.
When being monitored, tracked, and pushed to the cliff of choice, Lu Chen must find a third way between "saving the world" and "preserving himself" - if there is still a way on this road.
