Commissioner Yang still maintained his smile. At the start, his expression just lightened a little but now, it had turned entirely indifferent. He asked, "Come, Yao Jing, tell Uncle what happened exactly?"
"Uncle, I don't know what happened but from what they said, I could tell that the boys got into a fight because of Ye Jian. I saw that one of the boys had injured his arm so I ran over because I was afraid that Yang Heng was hurt too."
Yao Jing was smart. She didn't state categorically that Ye Jian asked Yang Heng to go out and fight. When she saw the adults, she told them only what she saw when she came out.
She was saying that she saw everything but she didn't know what happened. If she didn't know, it meant that she couldn't confirm her guess. If she was wrong, it was because she only saw what she saw.
