[Super mecha battle] + [Mortal protagonist VS immortal mecha] + [The protagonist does not kill randomly] + [No system] It can also be called: The Soulless Person in the Immortal Realm: Martial God X —— After countless ignorant war-torn times, we finally ushered in the golden age of the world of immortality! In ten centuries, a world where technology and immortality coexisted was completed. Mechas driven by spiritual power - also known as "spiritual armor" - are the mainstream of monks. Cultivation, spiritual power, magic weapons... These are the core of spiritual armor. But one day, a strange mecha returned to the world: Live ammunition weapons, industrial armor, old-era technology... Its owner, "Gus" from another era, is not considered "mainstream"! No spirit, no cultivation, no sect, but - his "power" can defeat the entire world of immortality!
