The planes of the heavens collided, space cracks spread all over Daxia, and alien races and beasts have been wreaking havoc for more than two hundred years. The human race uses cities as barriers and borders as defense lines to maintain balance in desperate situations.
Jiang Ningyuan, a senior high school student who traveled through time, triggered an eternal vision during the awakening ceremony, awakening a rare ability with no level and self-contained system - territorial control. He does not judge his level based on his qualifications, but regards protection as his foundation. He only defends but does not attack alone, but when he joins the army, he can turn decay into magic.
With a special recruitment order, he entered Daxia's top National Defense Martial Arts University and formed an elite team with three SS/SSS level geniuses capable of both offense and defense. During their half-study and half-fighting military academy career, they went deep into the border, faced fissures, experienced fighting, and polished their combat capabilities in the test of life and death.
From an ignorant newborn to the core of the defense line, from a soldier in the garrison to the pillar of the border control, Jiang Ningyuan single-handedly turned the protection into a sharp edge, using the military formation as the bone and the territory as the soul to prop up the great border wall of Daxia that will never fall.
