In the city of Lorne where steam roars, shadows grow in corners where gas lights cannot reach. Due to a strange "missing cargo case", dock porter Ma Tou accidentally came into contact with a bronze gear embedded in an old wooden box - an extraordinary relic that could glimpse the "grey fog". When he climbed out of the pile of corpses, he could already see the twisted outlines wandering around, and his ears echoed with whispers that did not belong to this world.
Extraordinaries lurk in parliaments, churches, and underground gangs. The road to the sequence is paved with thorns and madness: the commandments of the "Secret Keeper", the curse of the "Fate Weaver", and the price of the "Wall Breaker". Every step of promotion must compete with the alienated instinct in the body. Ma Tou not only has to avoid the "Scavenger" organization that is tracking the relics, but also, under the guidance of the gray fog, uncovers the truth that has been hidden for hundreds of years in Lorne City - the secret of the fall of the old gods, the origin of the extraordinary system, and why he can become the holder of the gear.
Above the gray fog, the threads of fate are entangled with each other, and the boundaries between mortals and gods are gradually blurred. Ma Tou must struggle between madness and sanity, choose between trust and betrayal, and finally become a web-spinner, or will he be backlashed by the web?
