Shield of the Nation

Global awakening of otherworldly channels, at eighteen one's class is set for life. Li Changfeng awakens the despised class of Shield Guardian, facing ridicule. His father died in battle, his mother struggles to support the family, and he steps onto the battlefield bearing a broken shield. As demons run rampant and cities fall, he holds the line alone for three hours, awakening a system—each hit taken increases defense by 1%, growing stronger with every blow! Withstanding the charge of an Ironhide Rhino, reflecting damage to melt the arena; besieged by seven demons, on the brink of death he breaks through, revealing the nascent form of a world-stabilizing body. From a scorned shield soldier to the military's top-secret ace, he uses his body as a shield, forging humanity's last line of defense. When the Nine Abyss rift erupts and a higher-dimensional invasion descends, he stands before destruction: I am here, the city shall not fall!
