The gods visit my shop. I travel across countless worlds with them. But then… “This is my sword, the Heavenly Tyrant Blade.” “This is the Ruyi Jingu Bang.” “This is the lightning spear I once wielded.” Their payments are… peculiar.

Traveling through the world of comprehensive martial arts, Xia An awakens the god-level corpse-touching system, as long as he touches the corpse, he can get various rewards!

I wanted to develop wretchedly, but I just became a six-door patrol, and I was ruthless at the beginning!

Ruthless: “The pervert will die!”

Xia An: “Obviously you rushed up by yourself, so can you go down to the ground now…”

With being involved in various disputes, Xia An’s strength is constantly increasing.

“Ding! Congratulations to the host for touching Ye Gucheng’s body, gaining 20 years of internal strength, flying immortal sword moves from heaven and earth.”

“Ding! Congratulations to the host for touching Yang Dingtian’s corpse, gaining a hundred years of skill, and moving the universe.”

…

Many years later, Emperor Ming looked at Xia An with a wry smile.

“Wu Wang, why don’t you be the emperor?”

Unrivaled Spear Knight.

The stereotype that knights must use swords is broken by the brightest star of a duke’s family. The hero that brought an end to the empire’s civil war. The name of that person is Joshua Sanders.

Despite his reputation of being called the empire’s unrivaled spear, he was bleeding dark red blood. Not just anyone but by the hand of his own emperor, Kaiser… “Kaiser! Don’t think it will end like this!!” Moments before death, incurred by magic circle, the spear that spent its years together with him, ‘Lugia’, started to emit an enormous amount of energy…

This familiar place, it can’t be… the stable that I used to live in when I was young?

My body became young?! Lugia, what the hell are you?

Joshua returned to his younger self. His ultimate revenge starts here!
