The story is very basic: MC living in Earth transmigrates to a murim world and want to become the strongest. In this world, everyone is "cruel", and only the strongest can survive, so the MC decides to become the cruelest, because that's how he can survive. He's quite merciless and reckless, just killing every single person who that threatens or disrespects him. Honestly, no story can make any sense when the MC is just killing the important members of every family. This story, as well, doesn't make any sense, because someone or something is always protecting the MC so he can keep killing everyone and be merciless. This is one of the frustrating points of this story.
So, I can easily summarize this story like this: some third-rate villain will act arrogant and say the MC is trash. Most of time the MC will kill the villain right away, but if he can't kill him, he'll swear vengeance and kill him later. Along the story, every 20 chapters you'll find a hot girl falling in love with the MC and an arrogant bastard who will die by his hands and shock everyone.
Every character is shallow with no development. The MC just kill everyone. The girls just fall in love with him because he kills everyone. The villains are stupid. You won't care about the side characters on the MC's side as well.
The art is also terrible. In the first chapters, it's completely amateur. Any beginner artist can probably draw better than that. It slowly becomes better, but it changes around chapter 350 or 400. I guess they changed the artist, or whatever. It was bad, but it became really generic by then, even worse than before. Sigh, you can't expect anything about the art of this one, it's really bad.
Romance is cringe. The MC is ruthless and looks like a demon when fighting, but acts like a virgin when talking with girls, and that's his second life...
Like every manhua, the translation is instable. I would reccommend to read Allen's translation in the first chapters, as he has good translation and explains a lot of the things of the novel at the end of the chapters, but he only translated the first 100 chapters or so. And even worse, most of the chapters in the first 40 chapters were broken or with missing pages, and only the version of Mangatoon has the complete pages, but their translation is terrible in the beginning, so I had to read both version to understand the first chapters. After Allen stopped translating, there are a few scans translating the story as well following his format of putting notes at the end, but after chapter 400 or so, it's hard to find good translation and Mangatoon is probably the only one translating. I'd like to advise Mangatoon translates the names of the characters, so you'll see some chinese character called "Ben", "Joshua", "Moon", "One Eyed", "One Arm", etc. Even the sect names are translated. And they use unique names to cultivations as well, but you probably get used to it. Currently, their last chapter is 718, and if you want to read after that, there's a site using MTL until chapter 863. Their translation is good enough IMO. You can understand most of it.
Final advise about this story: If you're willing to read it, you have to read until chapter 130 (around sub-chapter 42.1), everything before that is just a prologue. The chapters are really short, so you can easily reach chapter 130 in one day. After you reach this chapter, you can probably understand what direction the story will go. Like I said, there aren't many good points, except the MC is merciless and kill everyone. That's probably the reason people like this story, as the MCs never spare his enemies and always kills.
The chapter 863 is equivalent to chapter 713 in web novel, and the web novel is complete with 2500 chapters, so this webtoon will probably end with 3000 chapters if they adapt everything.
