Yep, very timely note to self.

Oh no what did he do :((. He knows what he did and this is not a surprise and if he suddenly gained a 'put actually 0 insolence into stuff he says' ability out of being in another world that would be a surprise. Also then other him might think he was an imposter. Other Jiang Cheng having about the same level of tolerance his has for when he is really trying to be properly obedient is very good, not all doms would be (or have been) that tolerant with him. This is a contrite and biddable-as-he-gets and properly appreciative Wei Ying.

Wei Wuxian will absolutely notice. But, nope, none of that, subspace brain, he is having no stupid reactions to other Jiang Cheng talking how Jiang Cheng usually talks just because it is currently a contrast to something.

...Wait he is getting to know the reason cultivation is usually started in childhood? He is! (This is going to get part of his brain suggesting that other Jiang Cheng must be at least a little sort of something like pleased with him, because he's telling him things; another part of his brain pointing out that other Jiang Cheng might just think he should know things about this world because he's in it, and knowing what causes problems at least makes him less likely to cause them by accident; and approximately all the parts of his brain distracted because alternative universe power information!!)

(aw that sucks about twenty. Though maybe there's a way around it that they haven't found here yet. Like other Jiang Cheng said it's not exactly the same thing as with a Foundation. Other Jiang Cheng said 'as the body is also growing'; it'd be pretty weird if golden cores were getting their 'is the body growing' signals from the Objective Font of Bodies Facts and not from the body they're in right. So potential step one, track down what they're getting as signals - did people already know about growth hormones at this point in history, he doesn't think so? (Wei Wuxian also doesn't actually know much about growth hormones. But he knows they exist!) Potential step two...)

(It takes him a moment to catch onto the live action metaphor, but he gets it.)

He has another moment like those times when he thought someone was speaking one of the languages he knows, and then his brain actually tried to resolve the syllables and they did not turn into words he understood at all. Then – ohhh! That kind of war. ...Or possibly not related to the war, but point is, something here is not at 'submissives are to be taught the appointed order of the world and show proper respect', and is at 'we don't respect those guys over there at all, look how much we don't do that'. - He's going to think this through some more later, right now he needs to answer the question.

Wei Wuxian partially suppresses a smile into his plate again. "Well, they're not all idiots - Sandu Shengshou." (It's a 'to be fair' kind of tone. These days a large part of the recipients of his opinions-at-length are Lan Zhan and Wen Ning, and it's gotten him into the habit.) 

Of course it's important to be aware and careful of dangers! (He does not say this like someone who came to this thought entirely independently). But that just means you have to figure out the way that really works, right, you can't go avoiding anything in the vague vicinity of 'something bad might happen'. If you did that you'd never have - surgery, or internal combustion engines, or fertilizer let alone dynamite! People get all nervous when it's power use because 'you can't understand it in exactly the same way as everything else' and 'it's hard to see what you're doing', but that doesn't mean it's different, if you - 

(This time he kind of forgets to keep a hold on the technical detail, but it should be possible to get a general idea.

The general idea might remind someone of a cultivator earnestly and passionately explaining that really, he has absolutely found a completely safe and reliable way to fly a sword into a hurricane. When said cultivator is both someone who could come up with that - not just if anyone could but if no one could. And also someone you would find in the infirmary, with the attendant healers explaining that he tried to fly a sword into a hurricane.)

Or in other words, Wei Wuxian sounds like Wei Wuxian.  It's an unusual mix of comforting and ominous.  His frustration at being kept out of the loop is replaced with frustration at seeing a Wei Wuxian yet again say things that could get him hurt.

Jiang Cheng is aware enough about how people work to know that he shouldn’t immediately yell at Wei Wuxian for being reckless - that is how you get people to not open up to you again.  On the other hand, not pushing back enough on his Wei Wuxian’s risky behavior also didn’t work very well.

He finishes the last bite of his last meat skewer as he tries to come up with something that will neither result in an argument nor Wei Wuxian shutting down and refusing to talk further.  

"Make sure you think about all the ways something can go wrong and find ways to prevent them, instead of assuming that you'll never make a mistake or get unlucky.  Let others be the ones to take risks.  Talk things through with people who can point out problems.  Even if they're not as smart as you, they might be able to see problems from perspectives you can't."

“There are people who care about you.  If you get hurt, they'll be hurt by that.”

No matter how strange the other world and other Jiang Cheng and other relationship are, that couldn't possibly change.  No one with any sense at all could know a Wei Wuxian and not love them. 

The problem with talking is that starting to talk because a relevant dom wants him to has a real tendency to turn into talking way past the point where any relevant doms wanted that at all. (You'd think after all this time he'd be able to stop at something resembling the right point. Or maybe you wouldn't think that; not about him anyway.)

Other Jiang Cheng has not started looking happier again. (Is maybe looking differently not-pleased, but Wei Wuxian doesn't think he's going to figure out the details.) And now there's some silence. 

Yeah. He looks at his plate. And other Jiang Cheng's table. He reviews his note to self.

...Other Jiang Cheng is giving him advice on how to do power experiments he's not supposed to do?? (Mostly) good advice? (And also thinks he's smarter than other people??)

…Yes he’s immediately tempted. He might be stuck here for a while! Other Jiang Cheng is a completely reasonable authority figure for power use in this other universe where it’s different! Telling him how to do versus not do something is basically like permission, right? He doesn’t have to go all the way with anything, he could try some stuff out and when he got back to his universe, he’d still have the results - 

NO, Wei Ying. (First of all, power use experiments take a long time, assuming it even works the same here which he doesn’t know yet, and if he has time then priority is obviously the local power use. Second of all, he does not think his Jiang Cheng is going to sell him to this one or anything, so he’s still going home at the end of this. Third of all, he has given other Jiang Cheng one summary, and if other Jiang Cheng knew more than that (for instance, the story that he is still not telling right now) he’d probably come to the same proscription. And zeroth of all, he doesn’t want to tell that story, but he learned that lesson and it’s not one of the ones he wants to do again. And not when he’s more than 14 now and his brother carries Zidian.

And Shijie would be very upset.)

He should probably respond to the ?advice(/instructions). But, before he can do that,

Ow. And, other Jiang Cheng continues to be very good at telling him off. He looks at his plate again. (Is his Jiang Cheng going to pick it up from other Jiang Cheng? He shouldn't think so, right, his Jiang Cheng could have done what Shijie does, like Shijie does, if he was going to. But maybe it'll only make sense to him from another Jiang Cheng in some way.)

"I understand," sir "Sect Leader Jiang." ...Wow he's lucky he has kind of tolerant doms. That is not what anyone has ever meant by 'be honest and tell the truth to your dominants'. (He just -. He wanted -) Plate. Table. "Sorry. I mean, yes, Sect Leader Jiang."
