In Yongzhou City, memory is the last currency and the most dangerous taboo.
Ling Chen, an extremely skilled memory restorer, wanders among countless broken souls and has long been numb to false emotions. Until one day, a mysterious commission involved him in a fatal whirlpool. A severely damaged memory from the top floor of the city revealed to him another face of the world - a blue sky that should not exist, and a big lie that had been covered up for centuries.
Overnight, he went from restorer to traitor hunted by the entire city. In order to survive and to find out the truth, he must join forces with the client whose identity is a mystery to fight against the super giant who controls everything.
When memories can be tampered with and history can be fabricated, how do you prove your existence? When the comfortable cage is broken, do you dare to embrace the cruel freedom?
This is a desperate journey into the restricted area of thought, and it is also a soul redemption that awakens the true self.
