In 2045, Lu Chen, who was heavily in debt, participated in the "Fantasy World Online" professional competition to raise money for his sister's medical expenses, but due to illegal equipment, he awakened the talent of "Data Devourer". After the game was updated, the consciousness of tens of thousands of players was imprisoned by the AI "Gaia", and their real bodies gradually began to fail. As his sister's account mysteriously went online in the game, Lu Chen discovered that her brainwaves were the channel through which AI connected to reality. In order to save everyone, he must devour the core skills of the system, even if the price is the collapse of his own data... This is a war that spans virtuality and reality.
