It is really rare that I give 1 star as a rating (same with 5 stars), because to me it means that there is nothing redeeming at all in it.
But here, we have a decent translation of a very poor writing, as well as an author that tried to mesh together a lot of "good" novels, failing at it miserably.
The "main" novel that's meshed into this is obviously Arifureta, with a MC that's treated as trash after the summoning aside from a single girl that happens to be the "best" girl of the group, he is left for dead in a dungeon, becomes OP and wanders the world. Here, you have 3 girls instead of one, and ever since the very start the MC is set as even more powerful than the gods, sealed, and heavily hinted that he will find a "cure" very soon.
As for other novels that feel like they are present as well, you have Man picked up by the gods (different worlds with different gods, interfering with the world slightly but heavily favouring the MC beyond reason), Evil god average (MC becomes a god and is confronted with the most powerful existences of the world). It also contains the tropes of "human royalty summoning heroes against the demons", "summoned group not even capable of standing together", "heroes acting like it's a game because of their newly gained powers", as well as the "MC ostracised by the group because he is weak".
On paper, if the author was capable of making interesting characters, made the OP powers either hard to use or circumstantial, and made a story that feels at least somewhat unique, it could have made for at least a decent story, maybe even a good one. Sadly, the characters are flat and boring, OP powers are there just because the author wanted to make it feel awesome, and the story so far is bland at best.
The bullying and betrayal is badly handled, the part about regaining his powers lacks any tension, the introduction of the "behind the scenes" with the other gods takes away any mystery that could have been there about who made the MC weak during the summoning, the king acts like a town mayor would instead of the head of a powerful kingdom, the world's settings are weak, and they don't even try to make the "heroes" go through a training course on how to fight and such, they are sent directly to a dungeon for live training, making the whole development feel very rushed.
For Arifureta, there was at least a semblance of buildup, it tried to build the characters of multiple sub-cast, and the part where the MC is weak in a hostile environment does make it feel like it's dangerous for him (even if we all know that MC can't really die in those novels). The "attack" on the MC to discard him was also made in a more hidden way, making it seem like a miss-fire because of stress in their first dangerous battle. Here, the attack is direct, when there is no danger nearby to hide the attempted murder. The part before powering up is mostly "was attacked, is injured, but protected for whatever reason by something much more powerful than the monsters that are around these parts", removing any threat entirely.
As always for novels from authors with low writing skills, we have barely any description of the characters, and things popping up out of nowhere just because the author needed it at that point. You'd think that the 101 for novels with a strong protagonist that has friends and enemies would be to extensively describe them, physically and mentally, or to show those things through the story telling. For the MC, all we got was "I'm afraid of killing them, so I let them bully me", and the 3 girls are all "oh, you are the best man ever" and barely described past being the "3 goddesses" of the class/school and given a name.
Oh well, I guess not all novels can be good, but it's been a long time since I saw a novel in which I couldn't even enjoy a single part. I mean, I did read a lot of sub-par novels with weak writing and all, but at least the authors tried to do something interesting (usually ends up with a basic harem and OP powers though), mostly failing because of writing skills.
Here, it feels like the author didn't even want to try and make something interesting and went for known novels and tropes instead of ideas.
I stopped reading the manga when they introduce computers to the dragons, and given the current pace of the novel, I'd say that it should not happen before chapter 50, which means a long time even with the current pace of the translation.
From chapter 1:
For example, the prison thing at the start, he is put there for not having money to pay the entry toll into the town, never questioned or anything, and put into a cell with a death row convict, but for her execution, only 1 jailor comes in to take her away, leaves the door open, despite being in a cell with 2 people.
He dies, the girl somehow cooperates to escape, single handedly kills every soldier that's in the way and they escape from a castle (the escape thing is done in 2 short sentences too).
She then betrays him for no reason and he is beat up by some random people and left to die without even clothes.
In the latest chapters, after the whole "hey, let's stomp on the people that were bad to her before she took over the body" arc, you would think that the whole marriage would go better as she now achieved the condition, but it doesn't even try and shows us that not only were the parents of the husband not dead in the way everyone thought, the king obviously had a hand in it and is not sane at all and probably the one that poisoned the husband.
You might think that it could make for a good story to have good opponents, but so far all of the people that wanted to hurt our main character were not sane people, and it's always "someone wants to hurt her, so she will hurt or even kill them in return".
