Bright Sword: Starting at Cangyun Ridge, I Make the Independent Regiment Stronger

Gu Chang'an, a PhD student at the University of National Defense Technology, transmigrates into the world of "Drawing Sword". From the start, he is at Cangyun Ridge, helping Li Yunlong hold off the enemy.

Using what he learned at the university, he builds new weapons and applies advanced tactics, helping the Independent Regiment grow stronger step by step.

Old Li treats him like a treasure. The brigade commander repeatedly tries to bring him to brigade headquarters, the division commander gives him a thumbs-up whenever they meet, and the headquarters chief often summons him for special lessons.
