"What can it do so far? What are you hoping to do with it?" 

"Ultimately I'd like to be able to arrange for more people to be able to continue to have their normal personalities after they die, and learn more about what it's like to be dead and what about the situation needs to be further changed. My world's had eclipsed for a very long time but it's actually only in recent decades that many have been able to have careers in magic, so the upper limits on psionics alone, let alone in combination with cultivator techniques, aren't known."

"That sounds a lot like demonic cultivation. You're gonna have some pushback, even if you are all respectable Lan disciple at them." 

"If I do it with psionics it isn't demonic cultivation, in my opinion."

"You're definitely right. I hope people aren't too stupid about it." 

"Me too."

Wei Wuxian doesn't really stop talking, topics ranging from how kind Sizhui was to take his complaints of theft seriously to complaining about his donkey's stubbornness to interesting flowers they happen to pass. 

They reach Shan Village. 

Isabella reaches into her magic sleeve and drops off her latest installment of Earth Knowhow translated for the benefit of the villagers. While she is rummaging in her sleeve she also grabs a hardboiled egg and starts peeling it after she has deposited the letter.

There is a lot of Earth Knowhow on display in this village. 

"Whoah, what the fuck," Wei Wuxian says, openly gawping. 

"I've been importing information," says Isabella. "I stick it here, though in the long run it'll filter out."

"So all this stuff is stuff you have in your world?" 

"A lot of it's actually stuff that's obsolete in my world because the manufacturing base here isn't good enough to support the more advanced versions."

"Oh, that's neat." He glances admiringly at a glassblower's wares. "What is that stuff?"

"They're using the word for it in the Mandarin of my world, bōlí."

"What is it, though? It looks like someone worked out a charm to make water stay in one shape. With colors." 

"Melted sand."

"Oh, cool." 

"In Suan Yisabeila's world, they light rooms with tame lightning." 

"What. What, that is so cool!"

"They're working on that here but it's hard to do safely, and I have to translate everything, which means I have to understand it well enough to talk about it in a language that doesn't have its own words for it yet, and I have a lot of demands on my time."

"Melted sand, tame lightning, cool powers, you...is everything from your world awesome?"

"No."

"Aww." 

"I'm not planning to import anything bad though."

"You don't seem like you would!"
