"Oh...I see." Ruby looked at the mathematical symbol in frustration. "Hey, look, there's a Chinese character here. Is this the symbol for the word 'factory'?"
John happened to pass by. He lowered his head and glanced at Ruby when he heard her voice.
"This is the root sign! It's a mathematical symbol, not a Chinese character," Lauren whispered to Ruby.
"Well, that's hard! I must be good to be able to participate in this a month ago. Is my IQ all gone after this hit? Why do I feel that I lost not a month of memory, but more than ten years of memory?!"
Lauren burst out laughing.
The real Ruby was really cute.
Although she was a little stupid, her development was at a normal stage for someone of her age!
