A modern special forces king and a genius industrial designer both transmigrate into the world of "Drawing Sword". From the start, Li Yunlong mistakes them for spies and nearly has them shot. At the critical moment, the special forces king uses the Merit Exchange System to obtain flashbangs, miraculously turning the tables on a Japanese special forces unit and reversing the tide of battle in one stroke. From then on, one sweeps through the enemy ranks on the front lines with tactics decades ahead of their time, while the other uses the System in the rear to build up his forces and advance the tech tree. Together, they mend every regret in the original story, rewriting a tragic epic into a thrilling, triumphant legend.
