The Eldest Senior Brother of Dongfang Wuqiong's Sect in Brother's Pit

This is about events from decades before the comic My Senior Brother Has a Hole in His Brain. It contains many headcanons. The comic doesn't say much about what happened before, so I wanted to write about it. Most of this is my own imagination. I'm also curious about what Dongfang Wuqiong was like in the past. He was so adorable as a child. I can't quite say what Dongfang Wuqiong feels for his senior brother. I think it's mostly admiration. I haven't read Mo Da's novel of the same name. My headcanon is that the former eldest disciple of Xuanming Sect is Gu Ziqi's younger brother. Theme: Everyone has a senior brother
