Thanks for the chapter!
I thought chapter 2 said his parents were dead, that no one from the Qin family showed up for the funeral, and removed his father's name from the family registry? Or is that what happened to his family when he was Mad Emperor Qin, and for some reason similar things are happening to him as Qin Xuan? Or is this one of those manga where MC stood at the pinnacle with lots of knowledge before dying and reincarnated into himself at a much younger age? Having trouble keeping up with names. Xiao isn't a name, but is like miss added to the front of a woman's name, right? And Xiao Wu is the girl he gave scriptures to who never laughed at him, right? That Lin guy seems like a lot of other small fry who use their families' power and prestige to bully others and end up bringing their family down with them over a small slight.
