Top agent Lin Mo is betrayed by his superior, Zhao Fei, during a mission. At the brink of death, he unexpectedly awakens the Everything Stitching System, which can stitch together the attributes, concepts, and abilities of all things to create deadly weapons and special powers.
Using nails, gears, and firing pins, he stitches together a lethal spike. With wood shavings and scraps of cloth, he stitches up wounds and saves lives. Thanks to the System, he turns the tables on his pursuers and escapes death, taking refuge in the intelligence bar Nightingale.
With the 76th Division hunting him and the Japanese military police closing in, Lin Mo stitches together disguises to infiltrate enemy territory and combines concepts to create traps. Step by step, he dismantles the Japanese Sakura Plan, tears traitors apart, and outwits Section Chief Inoue Takehiko. In this turbulent age of espionage, he uses his stitching power to shake the world and become the most feared shadow spymaster.
