Uncle Hu left to make the arrangements. After taking a few steps in and before Gu Xin could say anything, a young Man in Black with a sword in his hand suddenly appeared. He bowed to Lu Zheng, " "Greetings, young master!"

"Du RUO, this is miss Gu, miss Gu, this is Meng Meng." Lu Zheng nodded. I've brought them here for some business, so they'll be here for a few days."

"Eldest miss Gu, third miss Gu, and brother Meng!" Du RUO cupped her fists at the three of them.

The two sisters and Meng Meng nodded.

Then, Lu Zheng arranged for du RUO to take Meng Meng to deal with Xie Nanfeng and the others.

Lu Zheng brought the two sisters to a room."Sister Huihui, Xinxin, you two can stay here later! It's late today, let's go to the magistrate's office tomorrow. Let's discuss how to do business with Madam Xie when we go to the magistrate's office. You guys rest first. If there's anything, just shout."

Gu Hui and Gu Xin nodded.
