After knocking Qi Xin unconscious, Xia Xibei showed a bright smile, then moved her to a chair.
Then, she opened the closet and took out the small bag inside.
Soon, she took a small bottle out of the bag. She opened the vial and poured the liquid into Qi Xin's mouth, then lifted her chin and let the potion go down.
Qi Xin swallowed unconsciously and soon fell into a complete slumber.
Looking at Qi Xin's drowsy appearance, Xia Xibei revealed a bright smile.
"Thank you so much! You've been a big help to me!"
In fact, Xia Xibei had wanted to find an opportunity to strike at Gu Yinglei before.
However, she hadn't thought of an effective way yet.
After all, it would be easy to make people suspicious if she rashly sought out Gu Yinglei.
Although she was not afraid of being suspected, she should avoid such unnecessary trouble.
It didn't occur to her that this time around, Gu Yinglei would also be here.
