Master Heaven and Earth is an old and respected member of the martial arts community. He has set up a school a few years ago intended to teach only to the absolute elite, people born with inherent advantages, bloodlines, and enormous talent that sets them apart from the gross of the population. If you're not born into the top 1% in terms of martial talent, he has no interest in you. No room for lesser legends.
The school itself is a small converted mansion that houses only two classrooms. The 'Heaven' class focuses on esoteric, internal techniques. The 'Earth' class focuses on more visceral, external techniques. Each class has less than two dozen students, making it the smallest martial school in the city.

As his nickname implies, Yang's special ability allows him to take phenomenal injuries without slowing down. He can still feel pain and in theory he can even die, but he earned his nickname when he was quite literally thrown in front of a speeding train. Although he took heavy injuries from that he still could walk away under his own power, which made people speculate that he might be immortal.
