"I have to try it out first," William knew the only chance he got was that this alloy wouldn't get easily affected by anything. As it appeared in this world and didn't explode, there was a good chance it'd sustain what he'd pour over it later on.
He started to change the shape of this alloy, forming something with six legs and three heads and tails. As he started shaping it, he impeded lots of the cores he prepared into it. When he was done, the final shape was giving the impression it was filled with bubbles or something.
He already worked on the cores, processed it by writing inscriptions and infusing them with different techniques of his. As for the alloy itself, he started gushing his different spirit elements into it, letting it absorb everything without showing any change on the surface.
"If I have enough, I'd have added wings to it," William stood in front of the special alloy he just worked on, and felt satisfied, "let's hope it'll work."
