The outer two layers are alloys, with a slightly thicker gray ceramic layer sandwiched in between.
Sitting in the alchemy chair, the goblin Gaga said excitedly, "Miss Chui Chui has provided metals of very high hardness. Engraving magic circuits on them is an extremely time-consuming project, which isn't conducive to mass-producing defensive plates for trucks.
Luckily, Miss Chui Chui thought of a good method.
We first lay out the magic circuits in soft clay, then fire it to make a ceramic plate, and afterward glue the two metal plates to the ceramic plate.
After testing, this Magical Protective Plate had double the defensive capability of similar metal plates of the same thickness.
And its weight could be reduced by a fourth."
Chui Chui had been using an alchemical robot's body to conduct research here with the goblins.
Her computing ability and design ideas impressed all the goblins here.
Even the technologically proud Gaga had to respectfully call her "Miss."
