So, it's the proverbial Author's review. Now, let me use this limited and much-visited space to clarify some things for those who are yet to read and those who have begun reading but are likely confused about some things.
1. In this novel, you are mostly spoonfed things, but a wealth of things are also left for you to read in between the lines. This novel was written with the intention of appealing to a thoughtful crowd, so erm... please make sure you fit that category.
2. Darius Stone, the MC, is not an edgelord as many expected from the synopsis. The comparison to Leylin Farlier from Warlock of the Magus world was not referring to their personalities or logical choices, but their moral choices. Unfortunately, some fellows came in hoping to see Leylin V2.0, not Darius Stone.
3. Darius is - as they say - isekai'd. Yes, but please - and absolutely keep this in mind as it is the whole point of the plot - he is not done so freely. He is brought to the world of Faust with a goal in mind, and majority of the actions he takes - whether you like it or not, or whether you feel its smart or not - are geared towards fulfilling that goal, which is to amuse the one who reincarnated him.
4, Please, for the love of God, hide your arrogance and ego. yes, the suggestions you made as to loopholes with the ability he acquires are grand, but you aren't the only one who can do 1+1. I, and the create/characters in the novel, can certainly think that far, and if it's not implemented, it means it likely would not work. This is in regard to the system mechanism as well as the ability.
5. If the above-mentioned things have bothered you, please use this as an official clarification for your doubts. If they haven't, please keep an eye out for them and when you encounter them, remember my words. It would make much more sense when you do.
Thanks for reading so far. If you have read a bit and want to leave some praises, you can also make a review or let me know in the replies here or in comments (chapter and paragraph) in the novel.
If you have criticisms, you can also leave those, and I will investigate and either give you an explanation, gratitude, or apology depending on the validity.
If you are part of the typical crowd who like to insult first and think later, you are also free to leave whatever comments you have wherever. Just beware that, heh, I also insult back, and quite scathingly at that.
