In the cyber city swallowed by thick fog, the economic collapse has given rise to a mysterious realm that swallows human life. Lin Jin was reborn from a tycoon as a tycoon to a low-level accountant, but he awakened the abilities of his previous life that were engraved in his bones - the killing instinct of a black market boxing champion and the cold sense of smell of a capitalist. When the bloody elevator involved him in the first death game, the blood-stained work card revealed a shocking conspiracy: this cage called "Fog City" is just a cog in the seven cities of reincarnation.
Rules are weapons and memories are chips. Lin Jin discovered in the mysterious realm that every person who clears the level will become an "anchor candidate" - their pain is the nourishment for ancient civilizations to filter out the divine vessels. The nurse Bai Fei who fought alongside him turned out to be a defector from the Monitor's plan, and the barcode on her chest contained the dirty truth about seven world restarts. A bloody clock tower hangs upside down underground, a girl in a red dress travels through the scars of time, and "Mr. Bell" from twelve eras whispers in his pocket watch. When Lin Jin's right hand began to become regular, he glimpsed the cruelest law of survival in the desperate memory of seven hundred reincarnations: the so-called weirdness was just a reality show watched by high-ranking beings.
It's a death waltz that dances with the rules. At the moment when the purity of the soul crystal breaks through the critical point, Lin Jin faces the ultimate choice on the top of the Babel Tower - become the icy core of the new world, or risk all the anchor points to detonate the seven cities. When Bai Fei's body was unsealed from the clock tongue, and when the young girl built a doomsday countdown among the building blocks, the answer buried deep in the cracks of time and space finally emerged: the most unsolvable rule is the eternal betrayal of human nature...
