"I reckon this'll work!"
Jiang Han lowered her welder's mask, grabbed five hot-coil electric hammers with magic, and poured magic into them with all her might. The intense heat instantly raised the room's temperature by more than ten degrees.
Heat-resistant skin activated.
Splash shield activated.
Rain of Omniscience, miniature form activated—if anything went wrong, she could immediately unfold Rain of Omniscience's magic to protect herself from the explosion.
"Heave-ho!" Jiang Han's Mage Hands gripped the electric hammers, forming a giant windmill configuration specially made for messing around, and clang clang clang, smashed them all down onto the unfinished mineral on the table!
To create a conductor with high transmission efficiency, the first requirement was that its material had to isolate magic as much as possible. Otherwise, after leakage and then long-distance transmission loss, one charge might squeeze poor Hanhan dry.
There were several candidate materials for making such an item.
But! They were all too expensive!
So Jiang Han put some thought into it (I reckon).
She wrote down a string of chaotic formulas (probably workable).
Running the formulas, she reached a conclusion: copper and quartz both possessed a certain ability to isolate magic. As long as she used the simple I-reckon addition method (anything you don't understand + threefold) to stack the calculations, roughly sixty-odd kilograms of copper plus a certain amount of crushed quartz could probably be hammered into a small box that isolated magic.
Anyway, resources were abundant in the Witch world. Basic minerals like copper were already practically worthless.
As for the weight...
What was wrong with sixty-odd kilograms? It was just sitting at home, not being carried outside. A little heavier meant it was solid!
"Hoo-hah!" Jiang Han stopped hammering the mineral with the hot-coil electric hammers.
