I Transformed into an Armored Warrior in the Song Dynasty

Wang Gang, 31 years old, is a low-level programmer in an Internet company and a standard workplace talent. After working overtime until he died suddenly, he opened his eyes and traveled to the border town of the Northern Song Dynasty - becoming a Song soldier who was about to be crushed by the Xixia Iron Kites Army. Good news: He has a set of super armor from the future, which makes him invulnerable and powerful. Bad news: He has no idea how to use this thing.
