Bright Sword: The Double Agent, and Old Li Calls Me Brother

After transmigrating into the War of Resistance, Lin Xiao becomes a lowly soldier in a uniform factory, spending his days working a sewing machine, until he awakens the [All-Purpose Warlord System].

Just as Li takes over the Independent Regiment, Lin Xiao uses a tactical simulation that astonishes the entire army to become the regiment's youngest chief of staff.

In public, he is a “god of battlefield tactics.”

He builds a special forces unit, masters combined infantry and artillery operations, and crushes Yamamoto Ichiki with information warfare, turning the Independent Regiment into a mechanized combined-arms brigade that terrifies the Japanese!

In secret, he is an “intelligence phantom” infiltrating all of East Asia.

He cracks the Japanese army's top-secret codes, exposes spies hiding within their ranks, and infiltrates the Pingjin region to build military industry and carry out assassinations.

Shinozuka Yoshio breaks down: “Is that Eighth Route Army chief of staff human or a ghost? How does he know every one of my battle plans?!”

Li laughs heartily: “In this life, I don't bow to anyone. The only man I respect is my brother Lin Xiao!”
