Soldier Jing Shang was transferred to the 125 Cold Weapon Research Institute Factory because of his hand and foot coordination problems. At the factory, he used the system to develop a super-strong red-patterned saber, and its performance shocked everyone. It happened to be a friendly match with Sakura Country, and the red-patterned saber shined in the match and defeated the opponent. Jing Shang also attracted attention from all sides, and many factories competed for him.
