That gym episode was hilarious, as the crew tried to hide little Nuan's power from the gym bros and try to make it look like the other guy did it! Only for him to return to his family's heirloom and fail to pick it up.
I also loved how the gym was dumbbell-shaped.
I have to say, Nuan's starting to become a favorite of mine.
Villain-wise... that yellow-eyed, white-haired guy is definitely the main villain and wasn't open to negotiation. The amount of trinkets in his umbrella definitely indicates he's strong, but we all know how Ling is. And Nuan too.
The Sword Spirit World hosted such a big dragon only for it to get ROFLstomped by Ling, who was looking for good material to make a sword for his Nuan.
And speaking of Nuan, I love how the sword spirit immediately went to her aid and aurafarmed so much that the dragon backed the hell away from fear only to get permanently ROFLstomped again.
But on the bright side, she has a spirit now!
