Bright Sword: I Draw Li Yunlong a Grand Plan

Modern military-industry expert Lin Yi accidentally transmigrates to the Cangyun Ridge battlefield from "Drawing Sword". Mistaken for a spy because of his modern tactical gear, he is captured by soldiers of the New First Regiment and taken to headquarters. Just as Li Yunlong, furious over his disobedience during the breakout, is about to execute him, Lin Yi draws on his professional expertise. Using the high-precision map in his backpack and analyzing radio signals, he pinpoints the hidden location of the Sakamoto Regiment's command post. He boldly proposes advancing five hundred meters through trench works so that Wang Chengzhu's mortars can reach the target and decapitate the enemy command. Impressed by Lin Yi's courage and tactics far ahead of their time, Li Yunlong immediately assigns Zhang Dabiao to take him to First Battalion to carry out the plan. Lin Yi saves his own life and begins his military career helping the New First Regiment turn the tide against impossible odds.
