The bulldog barked happily. "Woof!"
"What is 1+1?"
The bulldog hesitated for a few seconds and barked a few times. Little Yichen called out a series of numbers. "What's 3+9-4+15-80+2?"
The bulldog was stunned and looked at him in confusion.
Little Yichen burst out laughing. "Look, you don't even know such a simple addition and subtraction method and you keep saying I'm stupid. I think you're the stupid one! Stupid Youyou!"
The bulldog understood the word "stupid" and lay on the ground with a pitiful expression.
The Ragdoll cat, 'Lisa', gracefully sauntered past Youyou. She got onto the cat bed and curled into a ball.
Little Yichen said, "Lisa, come over here."
The Ragdoll cat licked its paws and turned its head lazily. It glanced at him but appeared indifferent and ignored him.
The boy said sullenly, "Lisa, come here. Be good and listen to me."
