A Millennium Sigh (Gb)

(Gb) In Era 10086, winter enveloped the cyberpunk world, and the Blue and Red Society of Science and Technology divided the world. Blue represents the cold and shackles of cutting-edge technology, while red represents the surging desires of the world. The upper city, California City, is dominated by power and prosperity, while the lower city, Soli City, is mired in darkness and mud. Class barriers are tight, and people are always in fear. The secret history that has been sealed for thousands of years is buried in the world: The ancient Y country was in retreat and exploring in pursuit of eternal life, and attempted to fuse human cells with special cordyceps bacteria to forge an immortal body. The forbidden experiment eventually collapsed completely, leading to the destruction of the country and the fall of civilization. In this catastrophe, there was only one set of perfectly homologous twin embryos left, which were forcibly separated and gave birth to Cheng Cheng and Chen Qiannian in this life. The two have identical looks, the same soul, and a deep bond with their brain waves. They are destined to be one and the same for thousands of years. On the top of the upper city, a noble daughter of the royal family inherited the family business on credit, took charge of the hugely profitable skin and restarted the agency. She has the cutting-edge technology to reshape flesh and blood and recreate skin. She has hidden ambitions and wants to overturn the solid chess game of the times. Until she unexpectedly met Chen Qiannian, who looked exactly like her. A deliberately planned technological transformation caused the twins to quietly exchange souls, and their destinies were completely misaligned. In a corner of the lower city, a young man was born in the mud, and all his life wanted to rush to the dawn of the upper city. He disdained his parents' warning that "going up to the city is a prison". He would rather be a canary in the clouds than a wandering swallow at the bottom, and devoted himself to getting rid of his fate at the bottom. His best friend Cui Yan is absurd and transparent, with a transcendent mind. He is lustful but not lewd, happy but not transformed, sad but not sad. He is a rare gentleman in troubled times, but he is ultimately different from the comfort of being obsessed with upward progress. The gentle and paranoid girl Chen Qiannian fell in love with An Yi at first sight and started a long one-way journey. She accompanies him ups and downs, and protects him in his pursuit of glory. The two people with different intentions have become entangled in the pull of time, wandering countless times between the dilemma of giving up themselves and fulfilling each other. Just as the love was growing, a sudden change occurred in Shangcheng. Chen Qiannian was accidentally abducted and disappeared out of thin air. Wrapped up by endless regret, he resolutely traveled to the two cities, persistently looking for his lost friend. From then on, the story runs in parallel: the exchange of bodies in the upper city and the undercurrent of power and intrigue, while the lower city walks in the snow to search for traces and has endless obsessions. Thousands of years of wheeling of cause and effect, technology and desire collide, all regrets and rushes are the destined endgame of the immortality experiment thousands of years ago. Purpose: Technology fills the gap of desire
