Turns out, Shen Yishu has been secretly tracking Little Juanmao for a while, seeking the truth about what's happening.
However, last night while stalking Little Juanmao, he discovered that someone was trying to kill Little Juanmao.
He didn't want to see Little Juanmao get killed and in a moment of panic, he stepped in to help. However, he was unexpectedly kicked down a slope.
Recalling what happened last night, Shen Yishu was still somewhat shaken.
"Are you sure they were trying to kill Little Juanmao and not you?"
"Yes! Those two guys had been following Little Juanmao for a long time... When I was sitting in the café across the street, they were sitting right next to me. As soon as Little Juanmao came out of the car, they began whispering about not letting Little Juanmao escape... I'm sure of what I heard; they were after Little Juanmao. Also, if I hadn't stepped in to help Little Juanmao, they wouldn't have attacked me."
Shen Yishu's words made me finally understand.
