If that's really the case, he needs to stand up for Jiang Xue.
"We're here to handle some matters," Old Sir Jiang replied with a smile, then looked at Mr. Mu and asked, "But Brother Mu, aren't you usually in North City? How come you have time to come to Xu City?"
Bear in mind, North City is much farther from Xu City than South City. What brings the elder all the way from North City?
"Nothing much, just here to play," Mr. Mu replied lightly, then looked at Jiang Xue and said, "Xue'er, Brother Jiang and I are old acquaintances. It's rare for us to meet today, so we'll use your place to have a few drinks and catch up."
"Alright, I'll go prepare lunch!" Jiang Xue nodded, barely glancing at Old Sir Jiang and Old Madam Jiang before leaving her parents' house and heading back to her own place.
