Chronicles of Heavenly Demon is one of many martial arts stories where the MC gets reincarnated for the sole purpose of getting revenge. The most interesting aspect of this one is that the guy becomes a member of a "Demonic" cult in his second life, which at least gives it a bit of a twist.
As is tradition, the MC swiftly becomes quite OP compared to his peers. So if you like stories where the main character is an arrogant guy who crushes people who are supposed to be at or above his level, you might like this one as well. Personally I really like seeing the reactions of the bystanders in those kinds of situations, which is why I like this one as well. The action is nicely coordinated and the art is pretty nice to boot.
Of course, there's also a story revolving around the other people in the cult who want to get more power, but as of now that isn't explored all too much yet.
If there's one point I'd have to be more critical about, then it's about the timing of the MC's "powerups". Each time he learns something, he gets to use that practically immediately. Assassins are sent in waves, each time a little stronger than the previous assassins, giving the MC a chance of catching up to the increasing levels for no real reason.
Overall, it's a nice OP MC reincarnation martial arts story.
