@The boomer
@The boomer you're pretty close but the person who gave our mc nano was his descendant and huge spoilers ahead ,
Spoiler!
The blade god they say about is alive and has the power to time travel , what it means is that the blade god is from the future from where our mc's descendant lives in and has been using time travel to change history to his favor and while there's time travel technology in the future it's banned to use, but the blade god flied under the radar and changed so much history that in the future the blade martial school becomes a industry giant should I say ? , you will see this all in the future chapters
Just enjoying the love given by these work of arts and repaying it back 😀
