Lin Feng, who transmigrated into the armor world for ten years, finally waited for the appearance of the nether demons and activated the armor system. Able to control multiple armors such as Xingtian, Feiying, and Fyr (Kuileifu), he possesses extraordinary combat talent, acts decisively with slaughter, refuses to be kidnapped by worldly morals, and is unbound by the Armor Alliance. Facing the successive rebellions of nether demons, Orcuses, and Orphnochs, as well as cyber bullying and misunderstandings from internet public opinion, he firmly upholds his own principles. His close friend Ye Feng breaks free from inner avoidance and transforms into the Teru armor to fight shoulder to shoulder with him. Together, they resist various evil forces, collect bloodlines and summoners, and steadily march toward the power of the Emperor Armor.
