@Beast Gohan actually, this mc is not so strong just bcoz of nano
In another timeline he became the strongest on his own
Saber god and co. disrupted the time line and made sure he dies in 2nd timeline
Mc's descendants created 3rd timeline and gave him nano, for both protection and to copy his knowledge on martial arts and strength
If he could become strongest once,he could become strongest any other time, so it's easy to copy his talent too
Tho anymore than this will be too much spoiler
I left this without spoiler bcoz many know upto this , i believe
Hope this helps 🙏
