(Anyone who want sth with more complicated plot line, fierce fighting, and deep emotional conflicts would feels negative about this for sure. Or someone who doesn't like reading about MC with a little resemblance to a goody two-shoes, nor fillers called SoL, for example.)

The strongest top 3 tier of swordsman are: Sword King, Sword Saint and Sword Master. Guess which he became right around v4 epilogue?

*Tick Tock*... Just stepping one foot into the realm of Sword Saint! *clapclapclap* It's doesn't seem fast at all after all that diligent training and life-threatening enemies he faces from time to time to protect himself and the heroine.

Look at that, the latest enemy is a weakened surviving Demon King's General hibernating inside a near-breaking sealed holy battlefield. What bad luck to be dragged into it, sigh. (def. growth device by author, but is said to be the holy place detecting them)

her losing some powers as a sign of "fealty" to the MC, without knowing

noble light+dark saint daughters

some parts are too boring, uninteresting, unnecesary to read, like the political strife. (btw just to skip the explanation of the situation makes u skip 3 chapters, and thats a whole lot for a 37 chapter volume

at the start of v2 author changed the main 2's ages (not a time skip, he just changed MC and saint 3 years older), amateur move and I m kinda annoyed

The main character is developed as someone who cares a lot for his village/parents yet there isn't enough build up to make me care or make his attachment feel real. I think it would of gone a long way to add some mundane family bonding moments like a dinner scene or something when he was young just to help create a relationship. Right now his mother barely has enough character for me to remember and the dad just taught him swordsmanship. There are also a few issues in relation to his powers. His skill magic sword is honestly just too random and game-like that it feels off with how this was suppose to be game came to life. The base ability of him unlocking swords with enough proficiency I think works great, even if you set up the unlock to have certain conditions that need to be met (i.e. an immense desire to live, desire to kill, desire to protect) where the main factor is himself. The part that bothers me is how he unlocks things like the thief sword & shield sword where he gets blades dependent on exactly one monster with traits specific to that monster. I just really don't like how his power is essentially set up as worthless unless you happen to run into the creatures that satisfy these secret swords (well, not completely but a lot weaker) and just overall I don't think it was necessary. I think it would of made for a better power of he can summon a sword that reflects his soul, when he wants to be non-leathal its wooden, when he wants to kill its sharp, when he wants to protect its a sword in the shape of a shield, his will determines the sharpness and hardness. This kind of ability allows us as the readers to get easy insight into his development and his desires but instead we just get a skill that forces him to farm and kill specific monsters. Overall while I think it has issues and plenty of points that could be improved its not a bad read and at least the author isn't doing sh*t like trying to be as disturbing as possible or writing like their bastard of a main character is a good guy after abusing a person he forced to be his wife. (Mini-rant from another book)

Now, this is the thing that pisses me off the most about this story is the title. Why the hell is he reincarnated as the mastermind of the story??? I mean, the story isn't bad but the title is very very misleading... Not once has he even remotely done something mastermindy... What I expected at the start was some hidden plot so the original Ren fakes the deaths of licia and the headmaster but instead its just some guy training with his sword and being a normal protagonist, and I'm not saying there's anything wrong with that, just that the title should be something else. Rens original character wasn't even a mastermind, he just killed some important people and disappeared. Plus whats up with how dependent he is on his skill. He got the skill magic sword as a reincarnation bonus or something along the lines of that so Ren didn't originally have the skill yet his previous self was able to become that powerful, and judging by the dialog of old ren killing old licia for her stone that means he had that power, but if he had that power then what was the point of the MC unlocking the skill in our world, he could of just reincarnated as ren as the bonus clear reward.

*From him going to the fort to rescue the adventurers;

*From him meeting the second love interest for the first time and the author trying to force the relationship between the two in this first encounter;

MC goes to rescue a figure in the blizzard fighting a group of monsters:
MC: Oh my god, we fight so well together, it's like this strange person that I can't see the face because of the blizzard knows me so well!
Stranger: Oh my god, we fight so well together, it's like this strange person that I can't see the face because of the blizzard knows me so well!

Dude, whatafock, it literally happens like this, it's so forced and poorly written that I was embarrassed.

*So there are all the times that the two interact in this fort, the author makes for an unexplained and forced tension between the two. And it's really unexplained, it's just the author trying to force their relationship down your throat.

And from here until his fight with the resurrected dragon is so s*upid and poorly written that I don't have the patience to write everything that's wrong, since it's all poorly written and bad.
