So this idea came due to two fics I have read before which involved Shen Jiu ending up with or both of Liu Qingge's parents(mostly the one were he ended up with both of his parents).

We all know how most of the Peak Lords hate or dislike Shen Jiu due to misunderstandings and their own assumptions so what if they mentioned this to one of their family members(siblings, parents...even grandparents since taking in account their world, their grandparents could easily pass as their sibling if needed...also, all peak lords except Shen Jiu and Yue Qingyuan come from noble families that treat the peak lords well even if they aren't the heir) who got curious as they had heard people from places they visited talking well about the Qing Jing Peak Lord especially the two Shu(who will be Ning Ying Ying and Ming Fan's mothers) of two lords who said he took their kids and saved them from suffering at the hands of their siblings and the other wives.

The two images didn't fit together so they decided to investigate on their own starting with the rumours about Shen Jiu being lecherous as they all visited the Warm Red Pavillion(disguised so the Peak Lords had no idea about it) and watched how Shen Jiu simply taught the girls, entertained a few clients, got or shared information and at the end just literally slept beside the girls.

Then they decided to find out the one about him having designes for his female disciples are true by meeting them while in missions and wondering about how it was to be a Qing Jing disciple with the excuse of wanting a younger female member of their family to join Cang Qiong but weren't sure if Xian Shu was a good peak for them. This lead to them finding out that Shen Jiu treated them all with respect and even became a protector and parental figure to many of them(especially Ning Ying Ying).

With that, they decided to talk with the male disciples as it was said that they were extremely abused by Shen Jiu but the only thing they found out was that Shen Jiu trained them exactly as he had been trained and took in mind to be more severe to those who fit a physical cultivation but compared to how the Bai Zhan Lords trained their students, he was nicer.

They didn't think there was any more need to investigate any other rumour since the severe ones were proven to be false but they decided to investigate Shen Jiu further and found out about the Qiu family and how much Shen Jiu suffered before snapping and killing all male members of the family and servants.

Soon the families found themselves pretty disappointed with the Peak Lords but didn't act on their disappointed, they choose to join the Qing Jing Peak as guests(either students in case of a sibling or teacher in case of a parent or grandparent) to have the opportunity to meet Shen Jiu in person but they didn't expect to soon find themselves endeared or in love with Shen Jiu while thinking that bringing Shen Jiu into their families might be the best revenge to the Peak Lords.

If they adopt Shen Jiu or ask him in marriage(it can be a harem if you decide to do all families at the same time...you can use this idea with only one family but as I didn't want to specify one, I'm talking about them all...and I admit that it would be funny to see the Peak lords reactions to finding out that a family member married the same person of the other peak lords family  and later find out it was Shen Jiu xD).

So they slowly court/bring Shen Jiu to the family but a few things follow canon(Luo Binghe isn't bullied and knows that he is being treated like all the other male disciples so no revenge from him as he assumes Shen Jiu pushed him as it was revealed he was a demon, Liu Qingge does not die but I think the rest can follow PIDW canon) until the trial that still happens due to Qiu Haitang approaching the Old Palace Master but it does not go as he expects as the Peak Lords families interrupt the trial to show evidence that all the accusations are false and Shen Jiu had been in a dangerous qi deviation when he killed the Qiu males and servants.

The reactions and anything else is all up to the writer.
