A night hunt goes wrong when the group encounters a Qiongqi. While protecting his nephew, Jiang Cheng is hit with poison by the beast. They don’t have time to research an antidote, but prolonged dual cultivation with another cultivator will neutralize the poison... When he’s chosen for the job, Wei Wuxian is surprised, and determined to give his shidi a good time. Alternatively: In Which Yunmeng Recon Happens While Wei Wuxian is Balls Deep In Jiang Cheng.

Wei Wuxian interrupts his musing. “Do you want to try that?” Jiang Cheng glances at him, being careful to keep the lower half of his body flat on the bed. Is Wei Wuxian stupid? “Who wouldn’t want to try that? But who would,” he falters, “do it for me?" Wei Wuxian is fiddling with the blanket but his gaze when he meets Jiang Cheng’s eyes is daring, not shy at all. “I’d do it. To you,” he adds, in case his meaning wasn’t clear. “C’mon, Jiang Cheng. You’d like it, huh? Let me. Let me suck your cock.” He’s pouting, an expression that Jiang Cheng knows to his bones means trouble. “It’ll be good, I promise.” How many times has Wei Wuxian coaxed him into something foolish with that same tone of voice and that same smile? And how many times has it ended with trouble for Jiang Cheng?

They figured out that Wei Ying’s parents had died, and Wei Ying left alone, when Jiang Cheng’s fingers started scabbing over. After all, that’d been the agreement: Jiang Fengmian would consent to his wife’s proposal to engage his eldest daughter to the Jin sect’s heir, and in return she would agree to allow him to bind his best friend’s son to his own the way he and Wei Changzhe had once been bound, before the latter dissolved it in order to marry. A soul binding contract, allowing the wounds incurred by one to be shared with the other – a life-saving panacea, halving the severity of the injury by splitting it among two people’s bodies.

chengxian thought: turnip sales aren't cutting it, so wwx freelances out of a yiling brothel. jc, blowing off steam on one of his periodic trips to check up on him, asks for whatever the madam recommends and, welp, there's his brother. jc writes this off as a charitable donation. I did not intend to put any further thought into this but just like, the idea of the moments where wwx is still laughing off the coincidence and jc has already decided to go through with it, to insist, and wwx slowly slowly gets there

Jiang Cheng finds out about Wei Ying's missing golden core, and decides to fix it. With books. And his dick. Lan Zhan is there to help.
