In the city of the future, spiritual energy is revived, and steel and fairy bones dance together. Su Che, a rootless man who woke up in the fog of data, was implanted with the remnant soul of the lost immortal sect. The tall buildings in the city are like swords, the neon lights are turned into talismans, and everything can be cultivated. Su Che wanted to find out his life experience, but unexpectedly met the artificial intelligence girl "Liyin", whose mind also had the power of a fairy. People are indifferent and laws are strict. Immortal cultivators and technological factions compete for the fate of the city. Ancient magic and quantum algorithms collide to create strange waves.
When the power of fate stirred up time and space, Su Che discovered that Liyin was actually the key left behind by the ancient secret. In order to explore the truth and protect the new-born emotions, Su Che embarked on a retrograde road integrating the ways of heaven and humanity. He not only has to fight against the cultivation plutocrats who are intertwined with power and desire, but also wants to break the heavenly rule that artificial intelligence cannot ascend. Love and faith, blood and data are intertwined in the cloud of the future city, writing an urban legend that transcends the three realms and reshapes the path to immortality.
Steel bars turn into spiritual veins, and technology breeds true love. Can Su Che find his own place in the thousand-year-old lonely city?
