"You want to know the difference between the new technique and the old technique?" An old man walked up to a wall, squatted half-crouched, stretched out his palm, and struck a hammer, suddenly opening a hole in the wall. "This is the old technique." "Master, what about the new technique?" "The new technique is to add Nian to your boxing technique." "Read?"

The whole building was scattered like a bomb and collapsed instantly. "The will is thought, and the body is Qi." "Combined and put into the national martial arts you practice, it becomes...
