Give MC the Dragonslayer Swordspear from Dark Souls 3 and the Poseidon's template from Shuumatsu no Valkyrie. The first is because it is made from a metal used in the age of primordials and has a bonus dragon slayer attribute, in addition to the fact that Chastiefol serves more as a symbol of power or status as it is the equivalent of a crown used by human kings in instead of a weapon. The second is that I can't stop thinking about a combined attribute attack based on Poseidon's deities: sea/ocean, storms and earthquakes, a combination of penetrating attacks with the weight of the sea/ocean, the vibratory intensity of an earthquake and the violence of a storm.

I want to know if the MC will start extracting substances from the materials he is using instead of just using the raw material, for example he could separate the protein from meat or beans to manufacture something like a 'protein pill' enhanced with mana ou touki.

Why not give the MC an ARK survivor implant like in Avatar: A Survivor Lost on Pandora (written by The_Bip_Boop2003). You just need to give the MC the knowledge of engrams and a physical tracking tab, and as a bonus make all the things stored in the implant's storage space put the weight of everything stored distributed throughout the body, so you can do the MC put stones inside, to make him train his body evenly and literally all the time, and by adding a little gravity magic we can increase the effects of the training even more.

What I have to complain about is that the MC is very dependent on Ultra Instinct, honestly it's a good technique but it only becomes useful against opponents with a level of strength or speed close to that of the MC, and to make it useful against opponents with a highest level the mc would have to be completely in control during the Ultra Instinct state, an example of this would be if he was fighting mercury which moves at mach 10 even if the mc's speed increases 2 to 3 times that would only make him reach at mach 6 and even if he grows during the fight he would only have time to win by luck or the script, and I would like to point out that the mc is very fragile compared to the force he exerts or the speed at which he moves at this point he already he should have blown off his arms or legs a few times because for someone who must exert a force of at least 100 tons and moves at mach 1, getting hurt by colliding with a tree should be practically impossible.

I like how you preferred to start with defense and not discard it like many jobs do, I hope the mc doesn't sacrifice strength and defense for speed and dexterity, that would take away the natural advantage that the mc has, I would like to see the mc learning tekkai and applying it along with haki and hierro fron Bleach's arrancars.

The exaggeration I say is that no reason has been shown for the character to be afraid or uncomfortable with certain things like the dark in almost 60 chapters, the only thing shown is: "I don't want to do that" or "I don't need to do that" , and after some sentimental excuse like the time he fought with a goblin army, he could save the villagers but he could also choose to run away and ask for reinforcements from the guild, but he chose to sacrifice himself for people he doesn't know with the excuse of him being a fool and that his lineage would not allow him to be in a position other than at the top of the food chain, the mc showed himself to be someone who prefers to follow logic as said by him so why risk his own safety for them, in a scenario where he should prioritize his survival he sacrificed himself unnecessarily putting everything he achieved to lose due to a feeling of "impotence" and letting his lineage interfere in making the decision of something that should be obvious, and also the inconsistency of the lineage I admit that humans evolved facing extreme difficulties but not by choice but because we have no option, as our bodies are not strong enough to put us at the top, we have to use intelligence, ingenuity and cruelty as we end up extincting several species by Being an obstacle or because we were not interested like the Dodô or the white Rhinos, this suicidal maneuver made it seem like we faced the dangers we encountered like fools who cannot think and simply throw themselves over the abyss because we think it is the right thing to do.

Truly a master's work. Although I still want to complain about the exaggerated sentimentality, that would make MC's psychological maturation arc completely useless, and since MC's story before being transported hasn't been released yet, I can't complain about the character's progress or inconsistency. Now about the variation of the breathing technique, I find it interesting to use plasma instead of fire because plasma is literal raw energy, which absorbs the electrons that naturally pass through the object that is in contact to continue existing and consuming more electrons and consequently decomposing matter into primary particles such as protons, which when you stop to think about it is very close to what happens before the creation of a supernova where matter decomposes into energy so quickly and violently that the star's own gravitational field cannot contain its advance , thus causing its crust to explode and crush its core, now composed mainly of iron, into a sphere 70,000 times smaller with a minimum density of 10 septillion times the density of the material found on Earth, thus creating a neutron star, which makes me think about adding this concept mixed with the magic already present in the mc's body and soul, causing the energy to condense and become stronger/efficient than before and not leaving the physical body and soul aside since a weak container would simply explode making the idea simply ridiculous and impossible to practice.

Congratulations on transforming: a hitman, lord of death and darkness into a character with a hero complex.

I don't see any relevance in resurrecting the maid, it was clearly demonstrated during the story that the MC only gathered the main cast to have a harem and protect his world while he is not yet strong enough to go rampant across the multiverse, furthermore it was clearly demonstrated that the mc is neutral and only saves people who are useful to him. Other than that, I still think that the MC is very dependent on the shadow army and magic and leaves a little to be desired in the physical aspect, well he recreated Rokushiki and managed to completely block a dragon's attack but this was only possible thanks to the improvement magical, and as for the army, he uses it for almost everything such as: training himself and subordinates, collecting information, protecting his love interest; the only caveat is for magical research, which is the most used thing in the work.

Good chapter. As you have already placed an abyssal mythical monster as the representation of fear, I would like to present "the guy" as the representation of the mc's anger or aggressiveness.

Well it looks like I made some grammar mistakes, the real thing is "the hercules method", you can search as: hercules method Luther Strode the wiki has a better description.

I have to say that your story is giving me anxiety attacks because of the gap between chapters. I kind of understand that you want to take the story at a slower pace to get to somewhere around 200 or 300 chapters, but from the moment you put something like an external god as a brief/fleeting milestone I was hoping that MC's growth rate process would be a little faster, I know that after the Kimetsu arc he will reach supersonic speed and be able to lift a few hundred tons, but for me this is the basic beginning for a "journey to the multiverse " such as: Spartan(Halo) or the Astartes(Warhammer 40k), which respectively have something around 300 to 1000 times the physical capacity of an average human being, since the average capacity of a human being is 50kg when lifting weight and 3 to 5m/s in the race, and that's why I want to suggest something that will not directly change the mc's physiology as a genetic basis, that's why I suggest using the "Hercule's Method" which focuses on obtaining total control, mediation and balance the body, mind and soul through training and understanding the basic instincts of the human body, such as: eating, drinking, sleeping, generating offspring, fighting and protecting your possessions.

Praise you for listening to my pleas and not making the mc use a Katana as a frequent weapon. Regarding the story, it is really very good, a little too sentimental for an individual whose body and mind are constantly evolving? Yes, but it's compensated by the fact that the MC takes things seriously and is no longer one of those MCs with selective IQ like Goku from Dragon Ball who is only intelligent in things related to fighting.

Please don't make the MC use that rubbish weapon that is the Katana with the excuse of "because it's magic so it works", make him use a big sword like the Claymore or something similar and if it's a spear do something similar to Nameless King from Dark Souls 3, why? because a sharp weapon that looks fragile or has a blade that is too small for its size, in addition to looking strange and unpleasant, causes me tremendous discomfort. But other than that, it's a good story and I hope you keep updating it.

Dropped ?

I hope this story doesn't get dropped like the rest.

Demon-saiyan or Prime-demon.demon-saiyan can be used to reach Dragon ball Af ssj6, and Prime-demon can be done as something similar to Pickle only having a demon-back

Godzilla because his dragon form wasn't very only appeared in the Resident Evil arc.

put something like refined or higher level materials like: T1 wood, T2 wood... T10 wood.
