In the 781st year of the Tianqu calendar, the century-long war between humans and demons rages on. Amid the frigid winds of the Northern Frontier, Lin Feng, a lowly border soldier doomed to die, struggles to survive.
Powerful clans in the capital scheme against one another, and the northern defenses are on the verge of collapse. He has plenty of strategic insight, but can do little to change the fate of an insignificant pawn.
After a desperate battle, he unexpectedly acquires a golden finger.
It is a lost military text, The Northern Star Art of War, which can simulate battles, command a thousand troops, and awaken new unit types.
A lowly soldier of the past can now devise strategies from behind the scenes, triumph against the odds, and defeat the demon army’s elite forces time and again.
While others fight with brute force, he turns the tide with cunning. While his comrades are still desperately holding the line, he has already swept across the three armies.
After a hundred battles, wherever his banners point, no army can stand against him. In the end, he will lead an allied human and beast army to conquer the Everdark Frozen Wastes and take command of all the military forces under heaven.
