Actually, they really shouldn't have beaten up Zhao Xu at this time.
He was, after all, their elder brother-in-law.
Miss Zhao was getting married; as her elder brother, Zhao Xu's presence carried weight, and it would be inappropriate for him to offer toasts with a bruised and swollen face.
But the guard of Prince Beimo was in a hurry to return and report back, so they could only adapt to circumstances.
What's a few drinks compared to Beimo sending troops to help?
Worst case, he could wear a mask like them; everyone coming to drink wedding wine was an acquaintance anyway.
Ever since they caught Dong Chenglang and learned from Xie Jingchen that Dong Chenglang's body was with his uncle while his heart was with the Zhao Family—that he was their good brother's good brother, and now even Zhao Xu's brother‑in‑law—
This made him one of their own good brothers.
And that aura in his every move was just so similar to theirs.
Birds of a feather flock together.
