This one has a really good MC, he's kinda OP and seems to know a lot, if you like bold MC that is not afraid to antagonize some villains (like Martial Master and Against the Sky Supreme) this one is for you. The story doesn't have a lot of introductions, but the MC does have a goal of revenge, but this anime is about his journey of getting a lot oh power ups. The cultivation system does seems a little confusing at first cause it has more than one, but eventually it's possible to get a grasp of it. I watched because there were supposed tobe romance, and there is (eventually), and also a lot of girls have an interest in the MC.
The first girl may seem angry all the time, but often she has a reason to, she has a strong personality and she kinda grows on you. Hope it continues.
