High Martial: I'm an Executioner, Forced to Teach Gymnastics!

Smart protagonist / scheming / decisive and ruthless / slower pace early on

This world has reclusive cultivators in the Dragon Domain, strange beings among the foreign barbarians, ninja in Sun State, and mages in Maple Leaf Continent.

With the arrival of the Age of Declining Dharma, the legacy of immortal cultivation has been lost for centuries. What exists in the jianghu today amounts to little more than martial artists.

Li Buer is the latest inheritor of an executioner's lineage passed down for over a thousand years. He decides to enter the world and find a way for reclusive cultivators to transform into true cultivators. Instead, he becomes a gymnastics teacher at the best academy, spreading the appeal of my elementary school calisthenics, and accidentally becomes the first immortal cultivator in another world...

Executioners are divided into White Blades and Black Blades.

The Black Blade kills enemies; the White Blade protects!

Yet some use the Black Blade to protect the ones they love, while others turn the White Blade in their hands against their own kin.
