Infinite Realm Review: S-Mid, And the Genre's Smartest Dual-MC Structure

Why I tried it

I stared at this cover for a long time before I ever pressed play. That happens with plenty of series, but Infinite Realm was a strange case because nobody seemed to be talking about it either. I don't see it discussed much in the usual threads, and I went in half-expecting a competent B-tier series the storefront kept pushing at me. That is not what this is. Six books in, I think it's one of the best-built series in the genre, and I still don't know why more people aren't talking about it.

The blend, and the system

This one sits on the seam between cultivation fiction and LitRPG, and for a while I assumed it came from one of the big martial-arts-cultivation authors, someone in the Tao Wong mold. It doesn't. It's Ivan Kal, and the blend is his own.

Here's the hook: characters in the Infinite Realms have three separate ways to get stronger. Cultivation, classes, or skill development. You can't max all three. Each path has real pros and cons, and the series shows you both the good and the bad of every route across the whole cast. I have not seen another author run a system quite like it. Usually cultivation is just something characters do on the side, or skills are folded into a class. Three distinct tracks with real trade-offs is new, at least in my listening, and Kal spends six books actually using the trade-offs instead of treating them as a setup detail you're supposed to forget.

The trade-offs also solve a problem most long series fumble: the power ceiling. There are no true gods here, no Malefic Viper snapping his fingers and deleting a planet. The peak existences are strong enough that their abilities bend the Realms around them, but every power in this world costs something, so it makes rational sense that the people at the top don't just flatten everyone who annoys them. The strongest characters feel as powerful as they should. No more, no less.

The opening move

The series opens at the end of Earth's tutorial, with Ryun and Zach, the two most powerful survivors, in a standoff. Then it launches them into the Infinite Realms and feeds you their backstory in flashbacks.

I knew from the first chapter I was going to love this series, and this structure is why. You meet the finished products first, two hardened killers with completely different personalities, and then the flashbacks show you how two normal students from a world with very little violence became these people. The flashback chapters land exactly when they matter to what a character is about to do. It's some of the best character construction I've come across in the genre, and it starts on page one.

Two main characters, which is normally a problem for me

Full disclosure: I tend to dislike stories with multiple main characters. There's always one you like significantly more, so you spend half of every book frustrated, tempted to skim, waiting to get back to the good one. That bias colors everything below, so factor it in.

Infinite Realm runs straight into this problem. Ryun lands on the frontier, the Wild West edge of the Realms where the strongest make the rules and he carves out his place with blood and bone. Monster hunting, sect wars, an unknown cultivator making people regret underestimating him. Very fun. And his backstory is the kind that had me going, yeah, I'd have done the same thing. I'd make them pay too.

Zach lands in the Capital. Rules, old money, formal power structures, and a Boy Scout trying to figure out which cog he fits into in the greater machine. He believes in the greater good and keeps helping people at his own expense, and for several books I was putting up with his chapters to get back to Ryun. There are stretches where Zach is basically killing his break time by the coffee pot while Ryun is out on the frontier having the time of his life.

But the structure is smarter than my frustration. Because the two of them live in different halves of the same world, you learn the frontier through one and the Capital through the other, so when either of them eventually crosses over, no exposition is needed. You already know the rules and the players. That's when I stopped seeing the dual-POV as a tax and started seeing it as the reason the story works.

Zach flips the switch

Something happens to Zach. I'm not saying what, because you should come to it cold. What I'll say is that for several books you assume Zach will stay Zach, just with bigger numbers, and then he goes through a metamorphosis that makes complete sense in hindsight, and the guy who was a little too goody-two-shoes is suddenly, well, he's freaking Rambo. And the character who comes out the other side is arguably more interesting than Ryun, which I did not see coming from the guy whose chapters I'd been enduring.

So: do not skip the Zach chapters, even if he's boring you early. Just trust me on that. The payoff needs the setup, and if you bail on Capital Zach you never meet the Zach the series is actually building.

Ryun's growth runs the opposite way, no single dramatic flip, just continuous small changes as a loner starts accumulating people he cares about. The two of them are the yin and yang of the series, and either one could have carried a book alone. Together it's a better story than each would be separately, which is not something I say about dual-MC series basically ever.

Where it drags

The funny thing about reviewing this series is that the more I talk about it, the harder I have to stretch to find things to criticize. But here's my real complaint: the pacing varies a lot between books. There's no doomsday clock driving the plot, so some books are wall-to-wall sect wars, beast tides, and duels, and some books are settlement management and skill experimentation. In some books the leads barely move one realm; in others they jump two or three.

And the skill experimentation multiplies with the cast. There comes a point where you're five chapters into Ryun building structures out of void blocks and you're kind of over it, and then his disciple has to learn a slightly different version, so now you get the variations too. It's never pointless, there's very rarely grinding for grinding's sake, and none of the POV characters are dead weight. It just gets a bit monotonous in the slower books. One of the early ones, book three I think, though I wouldn't swear to it, has the most of this.

The one villain who bugs me

Kal gives everyone a backstory. His bad guys aren't bad for the sake of being bad; the world twisted them somewhere, and you usually see where. There's one recurring villain, though, whose reasoning has two glaring holes in it, and what bothers me is that his own friends never challenge them. These aren't underlings, the author goes out of his way to show they're his family in all but name and that he values what they think, and the obvious first objection anyone following him would raise just never comes up.

Maybe it's setup for a reveal. Kal has earned the benefit of the doubt on setup-and-payoff, the Zach turn being exhibit A, so I can absolutely be proven wrong here. But as of book six it reads like a blind spot, and I'd rather flag it than pretend I didn't notice.

Where it ranks

S-mid, with room to climb. The only thing holding it back from higher is track record: this series is six books in, and the Hall of Famers I'd rank above it, He Who Fights with Monsters, Defiance of the Fall, Primal Hunter, have twelve to sixteen books and roughly a book a year behind them. If the next couple of books keep this level up, S-high is on the table and I'll revisit.

A side note on Ivan Kal: he has other series, including one called Guild Wars, and I'll admit the names and the artwork never pulled me in enough to try them, so I haven't given them a fair shake. The word is that Infinite Realm is his best work. Given the care he put into this one, I should circle back anyway. Even a step down from this would still be worth hearing.

One production note: Phil Thron narrates all six books, no narrator swaps mid-series, which longtime audio listeners know is never guaranteed on a long run. The consistency matters in a story juggling this many perspectives.

Verdict

Absolutely worth the credit. My rule for this one: give it two books. Book one is strong but it moves slowly, because you're carrying two main characters plus both of their flashback tracks, essentially four perspectives, and that's a lot of ground-laying. If you're not hooked by the end of book two, it just doesn't have the things you want out of a story, and that's fine. Not every book is for everyone.

But if you are hooked, you've found one of the genre's quietly great series, and you get the bonus of being early to something most people haven't discovered yet. I look forward to seeing where it goes.
