[Ding! Your dog has been transformed into the Ancient Black Dragon Veligrpyh!]
James Kang, once the youngest heir to the multi-trillion-dollar Hart Global Corporation, has everything anyone could dream of: money, luxury, and freedom. But his life is hollow—friends are fake, family distant, and his days are a blur of shallow extravagance.
One late, lonely night, James gets a notification:
[Congratulations! You have been added to the Ancient Multiverse Chatroom!]
Thinking it's some cringy online role-playing game, he decides to entertain himself and plays along, proclaiming himself the "Supreme Demon Lord."
The group, filled with titles like:
[Princess of the Azure Seas]
[Dragon Emperor of Ashvale]
[Goblin Slayer Supreme]
[High Priestess of the Sun]
[Fafnir, the Pet Wyvern]
And they seemed hilariously invested in their roles.
What starts as a joke takes a bizarre turn.
The more Leon participates, the more he notices strange phenomena: glowing runes on his skin, magic artifacts materializing from nowhere, an elder dragon in his garage, and a sudden mastery of dark magic.
Things escalate when a private group chat, run by a perverted female King Arthur, invites him to [The Table of Beauties], a circle of god-tier roleplayers… or so he thinks.
Soon, James learns the truth.
The chat is an interdimensional nexus connecting real worlds where magic, legends, and gods exist. His casual banter and fake roleplay have turned him into a living, breathing Demon Lord, complete with a castle in Hell, loyal monster armies, and reality-warping powers.
To make matters even crazier, his “friends” start visiting Earth, and they’re nothing like he imagined!

Read to chapter 112. I came to it hoping for a slightly worse legendary mechanic. I felt disappointed. The writing is good, no errors or anything, and I think the story has some interesting things to it, but I can't stand the MC. In particular, his indecisiveness on hiding or showing his power. It also feels like the MC is wasting a lot of his time and throwing away his advantage. He also doesn't seem to use his knowledge from his previous life a lot.0 0 Reply

Honestly whenever I review a original on this site/app I usually start with stating how rare it is for me to read a original and let alone leave a review on one, and then go on a long rant about how most originals here are not good etc.Today I'll skip that to say that is truly one of the few great original novels on this site.I was recently craving some detective novels after I watched The Mentalist for the 4th time (only till the red john)So instead of buying a popular printed book I decided to find one on Novelupdateș. Com.There were fewCrazy DetectiveNetherworld investigatorGenius detectiveSuper detective on a fictional worldBut I didn't like the protagonist's of the first two. I wanted someone more like Sherlock Holmes or Patrick Jane from The Mentalist.The Genius detective is actually not badAnd then there's Super Detective. This I actually read all the available chapters on machine translation. Definitely not a detective story, well atleast not how you'd expect but a good Marvel fanfiction. Although first few chapters are pretty bad.Anyway during that time I came across"100 Ways to Solve a Murder"Honestly if it was any other time I would not have clicked on it at all. Because of how rarely I read originals.But it came to me just at the right time. Like it was fate.I had very low expectations and Although the reviews here did give me some hope.And I have to say those reviews are not wrong.It is a very good story. the author does take some inspiration from Sherlock Holmes for his character but really almost all detective shows or books are in some aspects.Just keep reading it.At first it might seem slowOr just some romance novel (even tho romance isn't bad either)I'm not a professional critique so I don't think I'll be able to give detail reviews why I like it. But I'll just say what I knowFirst the Grammar, which is very good, at least to me. I have a hard time immersing myself in originals here because of how many I find awkward sentences or wrong grammars. Here I had no problem at all.Second the characters. honestly if I hadn't read the story at all and someone described the male protagonists to me I'd probably wouldn't read the story at all. But here it fits and it works. I like the main characters.I rarely or even never read romance stories. But when I read only first chapters of the books which comes off more as a romance than a detective book I still read on. Mostly because of the characters.If I have too say, it is both a detective novel and a romance novel.Writing Style and Storytelling : I don't how to distinguish between bad and goodBut from what I have read I realy liked the style and I like the storytelling and that's all that matters.Anyway I would recommend giving this a try to everyone. It is definitely worth reading. I recommend reading the first volume (about 70 chapters? Before a review)0 0 Reply

I like this, but god damn it’s so slow. 27 chapters in and he is still level 1. There are things that don’t make sense, the first is his attitude towards the king. He was a gamer not Indiana Jones or James Bond, he comes off as rude and impatient something I feel an achievement hunter wouldn’t be. He is way to composed in his first meeting with a king, he isn’t at all surprised about his situation, and while it’s understandable that he doesn’t want to become someone’s servant after just arriving in an unknown world. It’s like he doesn’t imagine what type of power brought him here, and who holds the true authority over his life. Like come on do you really think a king would let you waltz out of his castle, if he had the power to bring you there, you’re expendable. It does state that it cost a lot of wealth and resources and that the chances of summoning is basically 1/5, that’s better than most loot boxes for legendary skins.TLDR great premise, execution of characters is lacking, world building is thought out, cliche in that he is going to be fighting against a super power on first arrival.0 0 Reply

Now I feel like i'm being a bit bias here but I truely love the story. Of course I've known this story almost as long as you (Sunk) have. It just leaves a deep feeling of pride seeing it grow and develop as if it were my own. Not only have you refused to abandon it, I can tell it makes you genuinely happy to write each chapter. (maybe besides the extra long ones lol) I'm proud of you, and even though I always am I don't say it enough.0 0 Reply

Why, you may ask? Because its the only fanfiction of RSSG compared to other story that are dropped, and it is a transmigration one, especially on the main character, :D (Hopefully there would be more) which i like, pls moar chaptah author. Anyways it's pretty good so far, i expect him, the main character to have more potential almost like a mutated monster, (in the story he at least gets a potion from the system that upgrades his body talent to mutated or close to mutated monster. Good luck man :) and be safe. 🙂0 0 Reply
