using "brother" (dàgē in chinese) is how they address someone who's close and older to them. it doesn't matter whether they're blood related or not.
In this world, yes lu minyu and xiaofan are brothers but if you read the chapters before, since the 2 tall guys and jinjin are the 3 most powerful and closest loongs in the heavens they are known as brothers
waitttt... why did the 2 tall guys call the baby their brother? I thought the brothers are the baby, the long haired guy and the other black haired guy who is a uke. im confusion
