Fatty clearly considered himself a one-in-a-million martial arts prodigy, the kind who could even get bamboozled by an uncle on the street selling the Tathagata Palm for twenty bucks.
Jiang He didn't go for tricking kids and firmly denied being his master.
Teaching some punches and swordplay to Xu Qing was good enough, so he wouldn't keep wanting Jiang He as his teacher. They could teach each other and call it even; after that, everyone on their own.
Jiang He walked across the road with Gong Ping, ignoring Fatty calling her 'Master' and quickly walked away.
"Why does he call you 'Master'?" Gong Ping was curious about this.
"Because I'm a hidden expert who can make Xu Qing cry out 'ow ow."
"Oh~"
Gong Ping instantly understood.
