MAJOR SPOILERS: Okay so here is the story in a nutshell so far so read at your own discretion. Woojin the MC was transported to another world in that world he had to survive on his own. He became a powerful necromancer that was feared and revered in that world. In that world a great evil was infesting the world and trying to take over yet the MC only ever cared to fight the evil when they encroached on his domain. After living in that world for 20 years he was able to find away to return home to his family and friends, once he arrives back on earth he finds that only 5 years have passed. Though he has lost his magic he still is stronger than an average human by a lot, he decides to go to where he use to live to find his family yet when he went to the train station Woojin finds out that the world has changed. This change is that now all the subway tunnels are dungeons on earth, and with this discovery Woojin gains some power back yet he has to re-level himself. The leveling in the world is like how it would be in a game and so after finding his mom and sis Woojin decides to challenge the dungeons to earn money and grow stronger again. Because he finds out that these dungeons are connected to the evil being who was taking over the other world. Many things happen after that such as finding a women he cares for, creating his own guild that turns into a kingdom and learning that the evil guy has taken over many worlds in that the taking of worlds is a part of a galactic game where domain lords battle to be one of the lords of a throne. That is all just the main gist of the story if you want to know more, of course, read the story. Hope you enjoy.

that's changed to he was as strong as, and viewed as an equal to, the literal gods of that world. He was able to take/kill whatever and whoever he wanted, and people left him alone because he (mostly) only attacked others as retaliation for them invading his land. And when he did retaliate, he was strong enough to single-handedly destroy any country that went against him.

one of the gods of the other world he just happened to run into

MC's character is the result of being a highschool student who was summoned to another planet, and had to survive by any means possible, for 20 years. In a planet where power is king, he grew to be a King. This meant, in order to survive, he was one of the worst character in the other planet, all in order to be able to go back home to see his family.
Well, imagine when such a character manages to get back home. While his education is lacking, his character, his solutions and goals is more in line with one who had been a King. Funny and tense situations are created when his supporting characters, who don't know his background, have to clean up after him.

Moreover, as a necromancer, the MC has the capability to see the purity of a person's soul. This has a big impact on the story writing, and MC's treatment of other people. Yes, MC is crash, and callous, and a jerk. Why wouldn't he, when he can see the other person's inner evil? Some reviewer complained about how a young girl with pure soul turned out to be a terrorist - and how MC did not see it coming. LOL. NO, the young girl is not a terrorist, she is simply used by a terrorist. She did not know she was strapped with a bomb.

This is reminiscence of the Matrix, and sword art online. Reviewers who are surprised did not read closely. Seriously, in the first pages of the book, the one granting him his return is a dimensional administrator. The big enemy is TrahNET. They are all looking for a Code. The author left so many hints about the reality of this universe that the big reveal was not about what, it was when. The only disappointment is that I think it could have been explained even further. When one meshes VR and Non VR world, there is no way it doesn't go into high fantasy scifi territory. If you are technologically inclined, at the end, you'll prob wonder about one or two things. Like, what, where is the backup system, why is there only one copy of it?

well yes, of course he was according to the past 20 years history of MC but the story is him given a second chance to redeem himself and not kill people just because it was an easy path for him

that MC was King for about 20 years and is still a King, just that the new people or government does not know it yet. He has the power to enforce his will and the urgency to bypass politics bureaucracy.

"How MC distinguish the terrorist" Well, 1 he has a power that can torture souls, 2 he can make some undead confess and 3. He can see peoples souls to identify who is guilty and rotten. Does that mean he killed only terrorists? No, but at least no innocents were killed. This is one of the moments were MC shows old behaviors, presenting the internal conflict of trying to do things the right way or his old way.

For one, the twist with vr was surprising but it made sense, the system, which unlike in most novels, had no real source, or a clearly defined one, made sense with that, so did some things that just seemed random, codes for example. It was nice to see this one take this specific route, and honestly, I wasn;t overally happy, but not too sad either, I hated how the ending went, Wish it at least had side stores!, Butterfly effect with tupper was nice as well, the ending was atrupt but I enjoyed the novel as a whole so that's why I gave it that name. There weren't any huge plot holes, a little suspension of disbelief but hey, its fantasy, I liked how the ending wasn't all the typical, imma a god now shiz, tho the scifi elemtn was.... meh,

enters a slightly tougher dungeon with a pre-existing team, who then abandon him and one other poor sod and try to PK them on their way out after - at which point MC massacres the humans, after owning the dungeon, and the aforementioned poor sod becomes MC's new scared-shitless simp-dongsaeng, aka MC's private secretary and manservant.
