He did as he said.
Chu yanhuan was a quick-witted girl who never dilly-dally. No one knew where she had gotten a bottle of spring wind crossing.
That day, Chu yanhuan went to the study early. Taking advantage of the fact that Chen Qingyu hadn't arrived yet, she tried to pour some medicine into the cup.
At first, she had only wanted to pour a little and play a prank on Chen Qingyu. After all, this was the study room. If something really happened, she wouldn't be able to stop it.
But with a shake of her hand, Chu yanhuan poured the entire bottle of spring wind crossing into the bottle.
This was the little girl's expression at the time:
Σ(ŎдŎ||| )ノノ
She was about to pour the water out of the cup in a hurry, but at this time, Chen Qingyu came in with a book.
Perhaps she felt guilty, Chu yanhuan put the cup back in its original place and pretended that she had done nothing.
