An S-class person with strong bones is sought after by all the nine states and vows to reach the pinnacle of martial arts.
Ling Ye, a C-level assassin, was ridiculed as a waste, but turned around and completed an A-level assassination, sheathing his sword without a trace.
He is the shadow of the top assassin in the Palace of Impermanence. He can decapitate invisibly and kill with one strike. He is a feared existence in the underground world.
Until the demon clan entered the territory and the Kyushu country was in danger, this killer with blood on his hands was the first to stand at the front of the defense line.
The bloodline chain is broken, and the inheritance of the country is revealed. His sword, which he wielded for missions in the past, is now only drawn to protect the eternal safety of the human race.
I'm a killer, and you want me to guard the country?
Okay, I'll keep it.
