Who Exactly Are You?

"What are you gambling on?" Grandpa Sun asked.

"A match of martial arts."

"Martial arts?" Grandpa Sun said in amusement. "Then what are you worried about? You have the same amount of courage as a sunflower seed!"

"Grandpa Sun, I know you're great but Master Sheng has been ill for a long time. Furthermore, his heart hasn't fully recovered yet…"

Yu Xi's concerns were well-founded.

"Well, you know how great I am right? And you know I've been teaching Master Sheng martial arts right?"

"Yeah."

"Then why are you worried? Are you doubting my teaching abilities or are you doubting his learning abilities? Or perhaps, are you doubting both of us?"

"Huh?" Yu Xi exclaimed in confusion.

His words made a bit of sense...
