Inventions not knowledge (I think )
But if he is using his knowledge to make an invention it's still going against the rules if nobody else knows about it? XD idk I'm a bit confused on this whole arc
I think the invention that they meant was like advance technology, while maybe the apple was just a new way to grow it. somethink layk dat i guess
It just has to be within an accetable range. He's not allowed to do things that's way off common sence, considering the time period he's in. He can't gather materials and make a plane, cure an illness with high tech, or sth similar. But introducing a new marketing tactic should be fine, since sharp ones would be able to create it iwithout prior knowledge in that period as well.
But I thought he wasn't allowed to use any knowledge from the real world??
