This Sword Has No Immortality

He was once a takeaway worker in Shengjing City who argued with customer service over two yuan of overtime fees. He was a shady programmer with a mind full of low-level logic and careful calculation. Until an ancient sword that cut through time and space, like a piece of unparsable garbled code, forcibly penetrated his originally mediocre reality. When the iced Coke in Shengjing City collided with the bloody storm of Qingfeng Continent; When the physical dimensionality reduction of materialism strikes, the superior array of all methods is torn apart. This is a story about how a "bug at the bottom of the system" can forcefully tamper with the common sense of heaven in another world.
