Dawn of the next day met Ethan already up early and scribbling something on a boom he had requested for.
Maybe he had gone insane after all, because no sane person would spend the entire night drawing and scribbling down formulas only to end up burning them.
But strangely enough, he didn't look the least bit sleep deprived. On the contrary, he looked pretty energized, probably a side effect of the system upgrading his brain.
Still, he couldn't let this go on as he was constantly distracted and wouldn't focus for a moment without starting to randomly design and calculate stuff.
Conveniently, one of the burnt notes contained an idea on how to fix this.
'System, open the TDI,' he mentally commanded, and the familiar lattice of holographic 3D boxes unfolded in the air before him.
The Idea Incubator pulsed faintly, awaiting his input.
