This Was Supposed to Be Cultivation, So Why Is My Master Teaching Me Military Fist?

I transmigrate to a world of immortal cultivation and bind myself to a Martial Arts Grandmaster System.

While others take on disciples and teach them how to wield flying swords, I insist on teaching them Tai Chi and broadcast calisthenics.

My eldest disciple's horse stance is so steady that he swings his flying sword like a dung stirrer.

My second disciple practices standing on one leg and ends up balancing on top of a crane's head.

Then the day the demon clan invades arrives, and the whole sect watches my disciples...

They dance in a square while beating the Demon Lord into a reaction image!
