I Awaken Emperor Armor from the Start, Leaving My Campus Belle Girlfriend Stunned

[Beast Invasion] + [Armor Awakening] + [Invincible] In Dragon Year 2100, beasts invaded Blue Star in force, leaving devastation and danger in their wake. To resist the invasion, humanity revived spiritual energy, built energy formations, and awakened Armor. By Dragon Year 4000, the spiritual energy formations had gradually matured, and countless Armor Deities had emerged. Everyone would be chosen by a Deity in their second year of high school to awaken Armor and become its summoner. After enduring trial upon trial, they would journey to the ancient battlefield to fight the beasts together, earning the admiration of millions. Or they would be exiled to the wasteland for the useless, becoming ants used to replenish spiritual energy… On the day Su Yun awakened, he summoned the ancient divine Armor, the Emperor Armor, shocking the entire school… An E-rank talent? But every time I swing my sword, I permanently gain one point of health, and my attacks deal true damage based on health. So, how will you deal with that?
