In the distant future, scientific and technological civilization has reached an ultimate form - the entire society operates with the Internet as its core.However, a mysterious "infection" in the past destroyed everything: the automation system was out of control and turbulent, and the urban structure continued to replicate and extend infinitely, forming a layered and boundless three-dimensional maze.Humans lost control of this huge city and became the target of hunting - ruthlessly hunted and cleaned by a defense system called "Safeguard". In a corner of this world dominated by cold machinery, there is an insignificant small settlement - the "Electro-Fishers".They struggle to survive, but they cannot escape the fate of extinction: on one side are the cruel and ruthless guardians, and on the other side are the increasingly exhausted food resources.At this moment, the girl Zuru resolutely embarked on a journey of searching for food, trying to continue a glimmer of vitality for the ethnic group.However, she accidentally triggered the sensing device on the tower, inviting a devastating response - a guardian unit quickly locked her position and rushed towards her village. When companions fell one by one in pool of blood, the way to escape was completely blocked, and just as despair was devouring everything, a wanderer, Killy, fell from the sky and became her only redemption.He is tasked with pursuing the legendary "Net Terminal Genes" - only it can restart this collapsed world and restore order and light.
