The newcomer was none other than Mo Canglan.
Mo Canglan and Gu Huaijin were friends despite the age gap, so of course he had to come to Gu Huaijin's engagement banquet.
Of course, besides attending Gu Huaijin's engagement banquet, Mo Canglan's main purpose was to see Gu Zhiqi and Gu Xiyue.
He just hadn't expected Gu Zhiqi not to come back. Fortunately, Gu Xiyue did return; being able to find one of them was already great.
In fact, there wasn't anything particularly important that Mo Canglan needed from Gu Xiyue and Gu Zhiqi; he'd mainly come to discuss medical skills with them.
So, the four–person chat group gained another member.
Previously the four of them had been chatting mainly about cultivation. With Mo Canglan joining, the topic shifted from cultivation to medicine.
At first, Mo Canglan only pulled Gu Xiyue into conversation, but gradually, Qiao Qingshu and Mo Weiran started asking one or two questions as well.
