MTL - Year of Herbs - Chapter 634 a few questions

Transmigration is the total rage of novels nowadays, and if the main character isn’t careful, they get swept up into the bandwagon, so this is a story from another continent. Magic? —— of course the main character won’t know how to use it, but what about knowing how to use electricity? Dou Qi? —— the main character still doesn’t know, but is inner power more strong?

A stern warning to male readers and your tastes, um, it’s like a breath of fresh air.
