In the cyber era where everything can be 3D printed, the ancient skill of embroidery has long been reduced to a lost "data garbage". A blind girl, Axiu, inherited the last Braille embroidery book left by her grandmother, and unexpectedly discovered that the stitching methods called "rolling needles" and "set needles" can tamper with the underlying code of the virtual world like knitting threads. When the giant technology company sent security to hunt her down in order to cover up the truth about the pollution in the data mine, Axiu could only touch the texture of the data with her fingertips and poke holes in the "fabric" of the firewall with an embroidery needle. Joining forces with her is the top hacker who once wanted to take advantage of her, and their only weapon is the gentlest needle technique that has been forgotten by the times.
