MC is able to cultivate using that lightning (it's just another energy source to him). The same applies to other things. The characters aren't believable. Few might be quirky, but they aren't believable. You can find young masters in this novel, even their fathers coming for revenge, after that, grandfathers. MC is sociopathic: alone all the time, doesn't talk at all basically, doesn't trust people (literally gives a trust scale of 0 to 5%), kills without batting an eye. It gets annoying how much he avoids social interaction. He's also oblivious when needed (and it doesn't even make sense): MC figures out how to directly use energy source A to cultivate, depleting it totally, which he knows about. Person B: Energy source A collapsed! MC: What? Why? (honest questions) In tags, this would be: strength-based society overpowered protagonist cold-blooded protagonist loner protagonist sociopathic protagonist "compassion doesn't exist" young masters arrogant people ... On the plus side, the cultivation system is neatly described, without too many specifics and numbers.
