Armor Hero: Reborn as An Mixiu, Bound to Merit, of All Things

Modern office worker Zhang Jian gets into a car accident. When he regains consciousness, he finds himself in the city of Happiness in the world of the first Armor Hero series. The original owner of his body was also named Zhang Jian, and was a reserve candidate to summon the Flame Dragon Armor for the ERP organization.

The original owner had weak mental strength, and was accidentally possessed by the residual soul of An Mixiu, one of the three squad leaders serving Lufa, who came from the Milky Way. As he teetered on the brink of collapse, Zhang Jian's soul fused with the original owner's body and An Mixiu's residual soul, forming a new consciousness.
