In New Chang'an City on a rainy night, neon lights and ancient charm intertwined in the humid air. Ling Xiao, a genius orphan hacker, is running around high-rise buildings and alleys delivering takeaways for a living. A compulsory order that paid extremely well but pointed to an abandoned place on the edge of the city completely changed his destiny. The consignee's strange whispers were like ancient spells. At the moment of contact, Ling Xiao's phone was forcibly implanted with an irremovable cyan sigil - and a virus called "Inner Demon" awakened.
It is not only a string of codes, but also an information plague that can corrode the human brain and create coma. Its roots are deeply buried in the lost art of prophecy and talismans. In order to save himself and others, Ling Xiao had to form an alliance with Su Rui, a college student who is proficient in ancient books, literature and history. Relying on his superb skills in the virtual "spiritual realm" and his street wisdom in reality, Ling Xiao embarked on a dangerous path of exploration. They gradually discover that behind all this is the technological giant "Mr. Li" who attempts to integrate ancient mantras and brain-computer interface technology to implement the "Jedi Tiantong" plan to format the consciousness of all sentient beings and become a digital god who controls everything.
The boundaries between reality and virtuality are becoming increasingly blurred, and spells and codes collide fiercely in offense and defense. Ling Xiao must travel between the two worlds, unite allies, and, under the siege and interception of the Longteng Group, uncover the truth of ancient secrets and fight against the ultimate disaster that can annihilate human consciousness. This is a last-ditch battle for survival, for freedom, and to protect the world of fireworks.
