Su Jinxiu is an embroiderer and is famous as the "number one embroiderer" in Jiangnan. The good news is that her skillful hands can make dead things grow into flowers, and even the imperial concubine is full of praise for her. The bad news is that she was kidnapped by the enemy's hidden espionage organization "Shadow" and became their tool. The leader of the "Shadow" was sinister and cold-blooded. In order to seize the border defense map, he forced Su Jinxiu to engrav the top-secret blueprint on the screen with double-sided embroidery. They think that an embroiderer who has no power to tie a chicken is just fish on the chopping board. As long as the needle and thread are handed to her, she can only be obedient. Little did they know that Su Jinxiu's hands, which were accustomed to holding embroidery needles, could not only embroider beautiful rivers and mountains, but also embroider secret codes that could kill people without blood. With every drop of a needle, she hid a loophole in the city's defense among the intricate threads; with every change of color, she marked the location of the enemy's forage in the undulations of the stitches. When the enemy leader marveled at the vivid picture of thousands of miles of mountains and rivers, thinking that he was sure of victory, Su Jinxiu silently cut the last thread under the dim candlelight. This picture is her masterpiece, and it is also the last funeral for these thieves. No system, no space, no superpowers. In this life-and-death chess game, her only bargaining chip is the tiny space on the tip of the needle. The world only knows that Su embroidery is stunningly beautiful, but they don't know that underneath this stunning beauty lies a brave enough to overturn mountains and rivers.
