In Cyber City in 2099, Lin He was a cross-time and space logistics pipeline repairman from the bottom to the dust. Every day, he was accompanied by maintenance orders leading to various doomsday wastelands. His only dream was to save enough money to upgrade the emotional module of the scrapped AI android "daughter" he picked up. In an accident, his body fell into a world of immortals that was being devoured by the "Data Catastrophe". In order to save a few monks who were about to starve to death, he exchanged half a box of expired military cans for a tattered sword manual that was used as a footrest. After returning to Cyber City, he was horrified to discover that this sword manual was actually the ultimate weapon that could cut off all digital shackles - [Original Code Level Sword Intent]. In an instant, the cyber capital giants who control the world, the human resistance forces trying to overthrow the rule of AI, and the super artificial intelligences that have quietly awakened all set their sights on this humble maintenance worker at the same time. And he just wants to protect the AI daughter behind him who is tugging at the hem of his clothes, deliver every "express delivery" in the cracks of the world, and by the way, give a "bad review" to this unreasonable world.
