When Lin Yue came into contact with the blocked ancient technology because of repairing the heart of the doll, he was involved in the power game under the protection of the nobles and the pursuit of the guild secret police [Eye of Time]; when the alliance led by Karl was in desperate need of strength and allies to break the situation in the resistance - a letter for help from the Coster family, like a stone thrown into a calm lake, led these two lone stars that had no intersection to a collision course.
Cold precision calculations meet the fiery will to resist, and the lost cutting-edge technology collides with the huge guild machine. In this maze where there is no magic, only machinery and conspiracy, will they become tit-for-tat enemies, or can they form an alliance that shakes Lorendan's power structure amidst numerous crises and betrayals?
Survival, truth, freedom - in this storm of technology and power sweeping the city, only the toughest souls and wisest minds can carve their own mark of the times among the rusty gears.
