Eternal Gun Soul

Zhao Zilong (known as Xin Zhao after time traveling), a former Blue Star Alliance Special Forces soldier, time traveled into the body of Xin Zhao, a border warrior on the Demacian border of the Valoran continent. The original owner, Zhao Xin, was actually Zhao Zilong, the son of an Ionian fisherman. He was kidnapped by Noxus when he was young and fought in the arena under the name "Viscero". After being pardoned by Jarvan III, he changed his name to Xin Zhao and became a warrior of the Fearless Vanguard. The time traveler combines the fighting instinct of the original owner with his own modern military literacy.
