At first sight "It Starts with a Mountain" is yet another lame manhua mixing isekai, martial arts and a system, for many that alone is reason enough to drop it right there, but sometimes (really rarely) something good comes out of giving this kind of manhua a chance, this is one of those.
Having said that, it's the story of a modern age guy that transmigrates (not clear) into a world similar to a game he was playing as a bandit, leader of a bandit camp that's in ruins, he then gets a system that forces him to do things to make the camp prosper, ranging from recruiting someone, to saving others or stealing people, cities, etc.. I'm aware it sounds dumb, but I recommend sticking with it for at least 20ch before throwing the towel. The story after the intro is that of a resourceful guy that struggles to thrive in this world, him getting stronger is not the main thing, but his whole group getting stronger is. The good thing is that the storytelling is good, the problems he faces, the actions his enemies, him and the characters take are believable and reasonable, it has a lot of comedy mixed in so some things look dumb but the plot itself makes sense and is cohesive, imo. Above all, the journey is not a flowery road, the MC suffers defeat or hold-ups a few times, he not always gets what he wants and so his victories are fought for, unexpected from a story with a system (of course there are some inevitable convenient moments, although it rarely is the kind that happens out of nowhere and mid-fight to same the MC).
As for the characters, the MC is great, he's a normal guy that struggles through, he's a bit detached at first for a person from the present thrown into a classic China setting were wars are constant, but it's later explained why, he's so far, a good guy and he's a mature character, he's willing to do what needs to be done to achieve his goal when there's no other choice, but would otherwise try the hard way to uphold his morals. Then there is a huge secondary cast with characters of different degrees of relevance, some are interesting, others annoying, others funny and so on, but they all feel distinct and well thought, also, the different female leads are more than there for decoration as it often happens in manhuas. Even the enemies are varied, from the dumb guy there to be slapped to smart or conniving adversaries that might actually win against him.
The art is quite good when it wants to (specially for manhua), the pace is quite good considering it's already over 300ch and it's still going strong, just know that there are long stretches without fights, the dialogues are fitting and even deep at times (though the translation doesn't help here) and the comedy has it's moments and is sparse after a while.
The negative points might be that the humor is a bit dumb at times, the existence of a system itself is a minus and the loli system is annoying at times (but later develops as an interesting char) and the story, while well told isn't particularly original but telling the story of the Toad village rather than only the MC is different than most (still not that uncommon thou). And, the harem, it's done slowly but there are too many maidens in distress that end up with the MC in the 300+ chapters that are out.
Overall, I'd say its one of the best manhuas with ancient China setting and it has been a surprise to read for the past year or so I've been following it.
Great thanks to Realm for the hard work, the translation is lacking, but it's better than standard MTL crap.
Edit: 500+ chapters in and still going strong this one is excellent.
