Snuggles and hairpets are exactly what he needs. Wei Wuxian fell in love with Lan Wangji, not someone who has words for things. 

"I love you. I love you so much. The last four years have been--really--hard." 

"Yes."

"It's okay. We're both here and everything's going to be okay. Even if--if--if somehow things blow up again. We can run away farther than the burial mounds, somewhere they'll never find us. But it's not gonna come to that. It's not." 

Terrified squeezing. "Cannot let things blow up again."

"Absolutely not. --Did anything blow up in the past four years that we should be preventing? I wasn't getting news from the outside world at all, so all I know is nothing blew up badly enough that they stopped pointing weapons at us."

"Jin Guangshan pardons Xue Yang. He should not get to do that. Nie Mingjue dies. Qi deviation, a year ago."

"I don't recognize the name Xue Yang, should we prevent whatever it is he's pardoned for?. Not sure how to prevent a qi deviation but that doesn't mean we can't try."

"He massacred the Chang Sect. We should definitely prevent it."

"Wow okay that sure is a thing to do. When was this? Why was this?"

"In the past year. I do not know."

"Well, we've got time, I guess. Did Jin Guangshan have a reason for pardoning him?"

Dubious look. He doesn't know Jin Guangshan's exact goal, but he's sure it was something greedy and terrible and underhanded. 

"That guy sucks so much. I wonder if it would be best to kill him too." 

"Mn." He thinks it's for the best.

"Have to be more careful to make it look like an accident...hm. Not as urgent as the Wen situation."

"No." They have time. Enough time that they get to cuddle for the rest of the day if they want to. Pet pet. 

Cuddling and being petted by Lan Zhan sounds like the best possible thing he could be doing, honestly. 

...

Well. Maybe not just that. There are several hours left in the day and they are still at the moment teenagers and also naked. 

That's a great point. Wangji twines their legs together as they cuddle and things progress naturally from there.

Eventually Jiang Cheng shouts really loudly that he isn't risking walking in on anything but he has food and unless they've developed a technique for subsisting on sex instead or cultivated to inedia already they should probably get dressed and come eat something.

It's so tempting to continue having sex with Wei Ying for another three hours just to spite him, but also it is pretty important that Wei Ying gets food. Making sure Wei Ying eats enough is part of Wangji's Wei Ying maintenance plan.

They can get dressed and go investigate the food.

The food isn't anything particularly elaborate, just campfire-roasted pheasant. It contains calories, which is the important thing. 

"Thanks, Jiang Cheng." 

"Whatever. Apparently you die in half of the represented futures, so, you know, if you starve to death now that wouldn't actually be less tragic than if you managed to burn to death while making poor life choices, so, you know. Don't die." 

"You...also die in half of represented futures." 

"What, really? Oh well." 

"Yeah. This time nobody's dying." 

...

"I mean, nobody we care about."
