Some bruises on arm pressure points started showing up this morning after the training last Sunday.
Turns out my master's martial arts teacher was the tall guy that looks like a marine fresh from the basic school.
The lessons were counters on the 4 gates and it reestablished my understanding of the fundamentals. While the master taught me last time, now it is his teacher that deepens my understanding of the principles and actuals of these counter strikes.
From these fundamental moves I can deviate and transition to more lethal moves like breaking bones or hitting vital spots.
