Escaping Kraft Viton's wrath was not as difficult as Michael expected. There was no reason for the old man to be angry, in the first place.
Michael might have destroyed the hard work of his old colleagues, but it was not an irreversible damage. Kraft Viton told Michael to write down everything again, or to copy his memories of the knowledge he'd acquired from digesting the Knowledge Wisps into Memory Crystals.
That was how Michael could keep the knowledge with himself and duplicate everything into Memory Crystals with ease as well.
It was a good thing that Kraft Viton was not angry. Michael wouldn't want to betray the old man's trust even before they started their training for real.
