If you feel confused or unable to keep up somewhere here, it's normal to be. That was close to 10 novel chapters in one sitting (around 5 more chapters skipped if they don't insert some more information later on). The letter from Ming Huayu is supposed to give context for Mount Daluo's status quo relative to politics, but, well, they gave you just two paragraphs, so don't feel bad if you struggle to keep up.
For the next person about to ask me where to start in the novel, again - beginning of volume 2, at the very least.
