Armament Haki? You Call That a Useless Power?

“An F-rank ability deserves to be called an ability?!” “An ability so useless it can’t even meet the support team’s standards? You don’t even qualify to take the ability test!” The Calamity Era descended. Countless unknown rifts suddenly appeared in the sky, and monsters known as Calamity Beasts emerged.

Advanced basic swordsmanship... And the Six Powers, which surpass the limits of the human body... Ling Feng carried an unattainable goal on his shoulders, ignoring the cold stares and mockery. To him, ridicule was nothing but a passing cloud. Insults were merely stepping stones on his path forward. When he had quietly fused all his powers into one, under the starry sea, one slash cut down a dragon! Only then did everyone realize... The student once tested as having an F-rank ability had already set out on a path so far ahead that they couldn’t even see his back. Many years later.

I killed it!”
