This appears to be some type of side story to "The Strongest Sage with the Weakest Crest," but honestly I don't care because it's horrible. MC has planet destroying magical powers, and he laughs at other people who don't have planet destroying magical powers, repeat x100. It's nonstop action and random encounters with zero explanation for anything. I suppose you have to read the main story to understand what's happening. All the characters are annoying and unlikable. It's essentially just pure power fantasy and every chapter is an excuse to draw more explosions. Don't care for the artwork at all, and it seems much betterin the main story.
