Stepping Up by Tossawary 
Shang Qinghua accidentally brings Luo Binghe in as a disciple of An Ding Peak instead of Qing Jing Peak. Thankfully, there don't seem to be any requirements that he step up and become the new villainous mentor figure, so he decides to ignore the problem until further notice.

Luo Binghe looking up to him is a dangerous sign. But as long as he keeps young Luo Binghe and Mobei-Jun away from each other, everything should be fine, right?

Servant to a Different King by Tossawary
As the head disciple of An Ding Peak, Shang Qinghua threw the plot out the window and abandoned his sect, and now he enjoys a luxurious life as Tianlang-Jun and Su Xiyan's most treasured and trusted advisor, as the happy couple rules over the Demon Realm together with iron fists. He has everything a transmigrator could want.

Unfortunately, there's only so long that the Imperial Advisor can continue to avoid another of Tianlang-Jun's favorite underlings: Mobei-Jun, the new Northern King. An attempt on Shang Qinghua's life inside the Underground Palace itself forces him back into the company of the demon who was once destined to kill his character - and who also once promised to kill him if they ever met again.

by foot it's a slow climb by Vroomian
So. Let's get this straight - I didn't set out to derail any plot. My plan was to lay low and stay away from canon. It's just...
My plans tend to fail.
Spectacularly.

of all the hands by Anonymous 
Xichen smiles, the first true smile Lan Wangji has seen in years. It brightens his whole face, smudges his graceful mask and makes it alive again.

“So it would not be too bad?”

Lan Wangji frowns in mute incomprehension.

“To be married to him, Wangji. We want to propose an alliance.”

//

Five years after the end of the Sunshot Campaign, the Yiling Patriarch has only grown in strength. Desperate to avoid another war, the Emperor proposes that he marry his younger brother, Lan Wangji, hoping to consolidate his power and take the Stygian Tiger Seal for the throne. He doesn't realise that Lan Wangji has never stopped being in love with Wei Wuxian, or what this marriage will mean to them both.
