Could someone please tell me, WTF is the writer smoking? He seems to forget a lot of things he is writing, or am I not reading it right?

A lot of spoilers, plz dont read more than this, if you dont want any. (Up to chapter 850.)

I am around ch 851, around the time Fang kidnapped his brother.

He is on a refinment turnmant and is going against the girl he threw off the mountain when he teleported and took the blessed land.

For some f*ing reason, no one knows that he is a rank 6 Gu master. He used a Gu to hide it, but it makes no sense. I know for a fact that when this girl sent him an invitation or something, she was talking to her parents, and they talked abt how he reached rank 6. Sure, other ppl around somehow dont know, although when he was attacked on his blessed land, everyone found out he had become a rank 6 zombie, but sure f it i guess, but then I remembered another thing.

I remember when he went to that big city with Bing, and that other girl he saved and send to her father, who was rank 5. It said that she is the youngest daughter, and that he has like 7 other kids or something (I read that ch a long time ago, so I dont really remember how many kids) But what i dont get is the fact that this rank 5 dude fell in love with the mother of this daughter of his and had her, but left just befor she was born to go to this city and reached rank 5 where he had a lot of wifes and kids, so how the f* did this girl become the yonger sister if she was the first daughter he had 🤣.

The story is really good and is one of my favorites, but things like this bug me so much, and i keep reading situations like this, but I shrug them off till this one, because come on. You can't be forgetting this many things as the writer of the book, you aren't reading it, you are writing it.

Or am I the one who can't remember things right? 😅
