The novel translation is readable if you don't mind the pronouns getting mixed up a few times.
The world set up is good and easy to understand. And there's also detailed descriptions of things as to why this is this and that is that. There's also pov of people other than MC sometimes (which I like very much in a novel). And the povs are done really well.
As for the story you can pretty much guess from the description. But is of better quality. The progress speed is slow and steady. If you like this kind of work then I don't think you will regret reading it.
Spoiler
At first the MC is hated and ridiculed for being defeated by a slime (which is not true but just a rumour). His childhood sweetheart dislikes him and leans toward the in game protagonist. She also believes the rumours and makes fun of him. I don't know the details of what the MC did before he got his memories back but still the childhood friend is not likeable. She even tries to isolate him from his few classmates who stand by his side. Truthfully I don't want the childhood friend route. The MC is currently using his game knowledge to improve himself to protect himself and his family. The grinding and other skill related things are fun to read. And they are not so cliche. But the story just starts here and there are many twist and turns.
The novel is supposed to be weekly released (but thanks to the sponsorship of a few readers the sponsored chaps are daily released from that you can guess how much it is loved) and the NU page doesn't respond as there are already 60+ chapters but it shows only till chapter 5. So, for more updates join their discord or go to their homepage (or about us page or whatever it is), there in the midst of other gems you may find this diamond.
