So the mc, despite being reincarnated with all his previous memories, he still needs an elementary kid to teach him some science... How old is he by now? Should be close to 30. The shame if this mc... He is a complete retard... Also, even though he had many years to figure out his powers, he had the guts to wait till the last day to start doing so... My god, I so hate stupid mc...
let's just forget that he is reincarnated and has memories of his past...but even after that, knowing his quirk is related to magnets and magnetic fields...are you saying he wasted these 10 years studing nothing or doing no experiments? and what foundations are you talking about? this isn't cultivation that you have to form a core before using magic or techniques...he could definitely experiment and learn atleast related to his quirk. Man what a loser and pus*y mc, I am dropping now. And this novel also has a author who deletes reviews because there ain't no way this novel have only 400+ 5 star reviews.
About Blackholes, and gravity manipulation... Magneto Doesn't have Gravity Manipulation. Gravity in the first place is a Space-Time distortion that was created with mass(to feel it, it needs to be big, like really big, planet or star level big). There is no 'mysterious' gravity energy that somehow related to the electromagnetic spectrum. Even his levitation works on principles of magnetic repulsive force, like two same sides of magnet.
