The novel adds a lot more details.
For one, getting to the point where he enters the room with the patient - lots of talking and stuff. Also, when he gets in, Seo Jun-ho doesn't pull out the core and freak out the old man but asks him to leave in advanced and stuff.
For two, you can kinda tell in the manhwa - with the sunset - but the "surgery" takes HOURS. Around four hours and he doesn't do it all in one push. Previously, using the core took around 2 hours.

For three, the surgery is not just absorbing the cold yin energy, but unclogging her magic circuits. He doesn't just shove the core on her or something, but he grinds it down to a powder and sprinkles it across her magic circuits to melt the yin energy and spends time fixing her magic circuits. Using Frost instead, he sends his magic through her circuits and... metaphorically picks up the ice and fixes the circuits as he travels.

Magic stat increases by 5. It hits 51 which finally makes magic his highest stat. Strength is 46, Stamina is 44 and Speed is 50. These are stats of someone around level 35, not his level of 13.

Also, Deok-gu asked "Wait, it gave you two?" when he saw the core. Also, Seo Jun-ho did ask for Dark-imbued gear too.

"Rumors on Mr. Main Character getting... a third wife?"

I think the monke tackled it.

All that praise,

yet he still looks down on him.

In the novel, the biggest difference is that Seo Jun-ho does not faint like that. He walks up to the corpse, cuts it open, pulls out and eats the liver raw -> giving him +5 to all stats. It did not that long but it felt like forever since it was GROSS! He washes his mouth out with some water, checks his inventory to make sure he got the core -> then promptly faints.

Since he woke up feeling really good, Deok-gu wondered if he was given an elixir or something when he was out. Nah. It's just his title.

It might sound like a meh difference - but between this liver and the blood petals from Leuf's garden, those two alone are +12 to his magic stat. He is prioritizing his magic stat like crazy because it is important to freeing his friends.

Well, novels are novels. Manhwa/webtoons are comics - or comic books.

You gotta admit, regardless of the content, the target audience for these are different. Sure, I like all the details and stuff that the novel gives but the manhwa doesnt, but some people do not care for it whatsoever. It is what it is.

Fight! Fight! Fight!

If you notice, when comparing the novel to the manhwa, I mostly just leave combat as is.

Again, the numbers are 10x off. He offers 100 million won; after the nagging, he doubles it to 200 million if you join now - but if you join later, it'll be 50 million won.
And he never says - nor thinks - that he'll surpass Specter. Specter is his hero too and he doesn't view himself over Specter.

The numbers are off, compared to the novel.
To be clear, they're 10x off. The initial offer is 150 billion won.
Then 200 billion won, then 250 billion won, and finally 300 billion won.

Like in the manhwa, Seo Jun-ho stops him and tells him that he'll take 100 billion won, because Specter sold the core to the Frenchman for exactly 100 billion won.
Fun fact: the Frenchman initially offered 500 billion won, willing to sell e v e r y t h i n g to save his wife.
Yes, the novel points out inflation and the many year gap.

Lastly, Seo Jun-ho took some magic bombs from the armory too.

Other than tiny details, the chapter is on point.
Tiny details that don't matter, like Cha Si-eun's hair length being a bit off - supposed to be at shoulder length. Also, she is supposed to have black hair.
Also also, he meets her the next day - to be clear: the day after that discussion with Deok-gu about cinder fox and all is done.

Not much to comment here. This is a fine enough summary of events compared to the novel.

Compared to the novel, the biggest difference in this flashback is about the fiend.
For 1) he wasn't some rando fourth option bought by a friend. All four party members have been hunting together since they became players.
2) He attacked while there were three (of the four) of them still alive. The fiend did attack Tushar Vishi from behind, but Tushar Vishi retaliated and straight up killed the fiend, but his left palm got cut.
There is no 6th wave, as Seo Jun-ho cleared it after 5 waves, fighting a total of 62 Leufs. They had to fight 4x that amount and they were down to the last 40 Leufs in the fifth and final wave when the fiend went for the ambush happened, so they were actually about to win.

We don't know how many Leufs were left when Tushar Vishi fell last - his last comrade sacrificed herself for him at one point, but I'd wager he was almost there; willing to fight by pulling the string of this bow back with his teeth, the man would've probably become a legend if it wasn't for the freakin' fiends. He hated the fiends and cursed them, which is part of the reason why he didn't put the bow in his inventory.

This differs quite a bit from the novel.
1) The journal is in Hindi, which Seo Jun-ho is fluent in, along with English and Korean.
Also to mention that the watch thing, the Vita, has translation features built-in.

2) The manhwa adds a LOT more context to this.
The journal was just that, a journal full of entries by Tushar Vishi. It spells out what happened plenty, but it doesn't go into depth like this.
Yeah, there is no explanation as to why he didn't use Confession of the dead.

3) He gets a "blood flower" with 7 petals on it. Eating each petal is gross, as it tastes of blood, but each petal gives him +1 to his magic stat. This is completely skipped in the manhwa.

The news article from the novel read: "Breaking News! The so-called Novice's Grave, the Gate 'Curse of Dawn,' has disappeared overnight." The headline makes more sense.
124 failures for Leuf's Garden, btw.

The manhwa just skips to when he's inside the gate but in the novel, he has to get there -> and on his way to the gate, he gets harassed by reporters. He gets badgered by them and has an internal "back in my day" moment when he is upset by them (rightfully so tbh). They keep going and he eventually responds with some hostility and goes then into the gate while they're still shocked.

The novel details that matter would be ones that show how Seo Jun-ho is less lucky and more skilled. That's about he biggest difference. Also, he fired the gun at the bottom of the coffin, not that this detail matters.
Also, he brings up the "Bringer of Spring" title helping his recovery.

Wait, I forgot one: the skill says "Allows you to look into the memories of the target. However, it only works on dead lifeforms."

Fun fact: he's reading Healing Cleric of Solaris - the novel is also available on Wuxiaworld (updating 1 chapter a day) - and here, it is: https://mangakatana.com/manga/the-healing-priest-of-the-sun.26140 (novel is almost caught up)
I do believe it is the same author's previous work and if I had to summarize it, it's "MID Overgeared." I'm not being a hand-waving dismissive jerk; I'm being almost literal as I've read Overgeared's novel on wuxiaworld - it is how I discovered wuxiaworld and fun fact: Overgeared is complete.

Anyway, details from the novel:
This chapter is pretty-spot on.
The signing bonus is 200 million won, annual salary is 1.5 billion won. In USD, that's like $150,000 and $1 million (rounding for convenience).
Seo Jun-ho asked about a weapon and was told to just take whatever from the Association's armory.
Also, he wanted to go right now, but due to how tired he became after fighting just 20 dwarves, he decided to delay it to train his body for 10 days. This training is time-skipped in the novel too.

In the novel, he makes a comment on how they ran away - which is nice and realistic tech.

I feel like this speech bubble is weird. Like, he starts of saying "there are 20."

Other detail: GUN. He uses a gun and shoots some of the goblins.
A detail that matters less: the wait time is actually pretty long. He watches a lot of people before it is his turn. Also, those are goblins, not dwarves. They are dwarves in the novel... whatever. /shrug

I know. To be clear, I'm not complaining. I'm just pointing it out, kinda like captain obvious.

Alright. I finished it. I agree with a lot of people who praise it. It's a nice solid 8 or even 9 out of 10.

The art is pretty awesome. Sure it starts off a bit rough but it gets better, a lot better. There are well written characters, plot and lore of the world and all sorts of plans behind plans behind plans. As it gets unraveled, you'll learn just how FREAKIN' SMART some characters are. Like one character literally has the title of "Brain" or "Strategist" of the cult and at one point, without skipping a beat, he drops information and a plan to completely overcome a difficult situation.

It doesn't do much in terms of humor, which is a good thing, but it is funny when the enemies are so freakin' screwed and they just have no idea how screwed they totally are.

I do wanna mention that this manhwa does not have the "Overpowered MC" tag and this is accurate. MC will reach a point of being overpowered but oooooooooh man does he have to WORK, struggle, and suffer for it.

There is an overarching plot that is set up really early on and it is addressed here and there. It is properly addressed by the time this ends.

No, it isn't rushed. It simply isn't draaaaaaaawing things out constantly. It simply heads towards the intended ending, gets there, and some salty people are like "oh no, it got rushed." Uh... no. Please, just stop and accept that it is ending.

Judging by the comments, the absolute worst part of this manhwa is waiting for updates. Well, that's not a problem anymore, so enjoy!

Also,
"Someone like me wouldn't have had to suffer."
Spoken by literally everyone who got wronged once and decided to blame everyone and everything else instead of something about it -> and eventually caused more suffering for far more people.

There is no sob story in the universe that would make me sympathize with you.
