The undead have descended upon the world? I possess a sword that can cleave the heavens once more!

[Zombie Invasion] + [Official Investigation Bureau] + [High-Level Martial Arts] + [Swordsmanship] + [Human Supremacy] + [Twenty Chapters to Take Off]
Wu You, who had hit the jackpot, awoke from the fog and found himself transmigrated into the body of a high school student with the same name.
In this world, monsters known as Corpse Species have invaded reality, and the official investigation bureau, as the only and strongest force, can only barely maintain a fragile balance.
As a newcomer, Wu You could only rely on the system panel called Sword Canon, which had traveled with him from another world.
And so, he began to improve his swordsmanship from the basics, gradually ascending to the highest level.
. . .
Years later, the zombie species launched a full-scale invasion.
Wu You, high above the Ninth Heaven, opened his eyes and looked down at the Corpse God and their army of corpses:
"Keep quiet."
"This sword can cleave the heavens!"
A magnificent sword aura descended from the heavens.
In an instant, all the Corpse Gods and their army of Corpse Species froze, then shattered into pieces.
This is Wu You's story, and it is also an epic belonging to all mankind.
The flame of humanity will never be extinguished, and the glory of humankind will endure forever.
Even in the solitude of the night, the blazing heat of the day!
