Knockout Powder 

At night, Xin Xiu gave Shang Wen a call. "Wenwen, I'm already at the door. Come out, the two of you."

"Okay." Shang Wen hung up the phone and called Jiang Yu. "Little sister Jiang Yu, aunt is already at the door."

"Then we'll go down now." Jiang Yu took her small backpack, which contained her silver needles.

She would never believe that Xin Xiu would suddenly be so kind as to invite her Shang Wen out for dinner. Just in case, Jiang Yu decided to bring a self-defense weapon. Sharp products were not suitable, so silver needles were the best choice.

Xin Xiu had said from the beginning that it was best not to tell anyone about this. This was a very strange request, so it reinforced the bad premonition in Jiang Yu's heart.

As Jiang Yu and Shang Wen didn't have any actual evidence, they didn't tell anyone for the time being.
