"As strange as it sounds, this single day… Or rather, the way in which I experienced it, is the source of all the information, knowledge and inventions that I have brought to this world. So let me elaborate on it a bit."
Rather than going all-in and attempting to explain the existence of the system which I wasn't really sure about myself, I decided that simplifying the entire matter to just the visions of the future would work better. Just like previously I told him that I learned everything I know by observing the nature, even though it was a lie, it still served as a proper way to teach him about the intricacies of the science.
That's why, going about the things in the way that I decided, even if it was a lie, would still serve the purpose I had to achieve!
