[being honest, it could be as dull as watching paint dry and sizhui would still politely listen, regardless. but thankfully, science sounds interesting and if senku wants to learn about magic, then he's come to the right place.]

Ah! What if, in exchange for your scientifics, I could teach you things about the magic from my homeworld? It's likely different than others on the train... unless they've also arrived here where I am from.

[good thing he's just as curious about other people, so he has no trouble immediately answering,] I am a cultivator from Cloud Recesses, which resides in Gusu! A cultivator is someone who has spent their life building a golden core through meditation and training. This means we are stronger and faster in battle, more difficult to wound and kill. One almost never falls sick and our life spans are longer than a regular human's.
