Isekai de Kojiin wo Hiraita kedo, Naze ka Darehitori Sudatou to Shinai Ken - Vol. 1 Ch. 5 - Soap

[Argolok]

@Owyn That's never the explanation for how they know though

 

[zyocuh]

Umm, How did she clean the floor in the 2nd chapter? I guess just water

 

[TamaSaga]

For a backwards civilization, where did the baking soda come from? We're talking about a substance that needs some advanced chemistry knowledge to mass produce.

 

[AzureD]

That baking soda has to be a mistranslation. It should be lye. Lye is easy to get and requires no special chemistry. You mix fat and lye and get soap. Don't need anything extra.

Actually it is odd that they do not have knowledge of soap. It is easy to make even accidentally and it has been around for nearly 5000 years.

 

[deadoon]

Baking soda(sodium bicarb, NaHCO₃) when heated in water creates sodium carbonate(Na₂CO₃), some water and CO₂. Sodium carbonate can be used as a Sodium hydroxide(NaOH) substitute, although it is less efficient. The earliest soaps were made with Potash of some form.

He has a loli and he's acting as a dick, what is his problem?

 

[A_Common_Crab]

This guy is either buddha or gay. There's no way in hell that a normal guy would be able to resist that.

 

[Northern]

They've got chariots and wagons, complicated architecture, glass windows and blacksmithing, but no soap. Soap has been in use globally on this planet since the mesolithic. It's literally made from fats and ashes.

Also the MC is a dick.

 

[darkcat28]

They have baking soda, but no soap? classy isekai logic

 

[Doomer]

she offered to fuck you the moment you met, if you want it she will give in, just ask man

 

[CivilSky]

i can only assume that people in this world do know about soap, but a 9-year old orphan that still marvels and coos at the market probably wouldn't.

on the otherhand is soap production common knowledge for japanese highschoolers? is there a chemistry class that has that as an exercise? was he a bookworm in the previous world?

or maybe prior knowledge of how to make things that most people just buy off of shelves is simply a prerequisite to isekai

----

nvm according to next chapter 9 year old orphan is actually worldly and totally in-tune with the worlds common sense.

 

[humbleoverlord]

dude... you can't use freshly made soap like that, it'll burn your skin... Somehow this mc randomly know how to make a soap but don't know freshly made soap is very caustic, it'll irritate and burn your skin, you need to let it cure at least 2 weeks....

 

[bushwhacker2k]

"What is happening at that time?"

No, the correct question is: "What does 3 o'clock mean?"

(Unless it's a specific Japanese phrase which implies a time-of-day and not a specific clock-time)

 

[flannan]

@gaigous - most technological processes used by isekai protagonists are the kind that are hard to get wrong. For example, you don't really need to know the exact proportions for making soap, you'll end up with some soap-like stuff anyway.
The more advanced ones are either made by people who have actual skills, by people who have extraordinary access to knowledge, or with super-materials that make the underlying technology easier. For example, Magi Craft Meister was a quite capable worker in his earthly life, and builds airplanes out of mithril, which is stronger and sturdier than materials available to early aviators.

@Acolytus - people know a lot of random technological stuff. I usually assume the MC just happens to know the ones he made, and not know the ones he did not make. It's quite fun - learning that stuff you normally can only find in a shop can be made without high-tech factories.
From my research, things that cannot be made by isekai protagonists start around the level of smokeless gunpowder.

 

[gaigous]

@flannan I'm aware, Magi Craft Meister clearly established where the knowledge came from, how his magic bridged various gaps, and he was an engineer in his previous life.

My issue is with all the lazy writing more than anything else.

 

[Kegaten]

Gee, that color page

 

[Notsuki_Ame]

Too many people talking about the soap and not enough talking about the cute loli, shame on you! Shame on you!

 

[Silwith]

So much crybabies? Its a fluff manga... enjoy the fluff and put your dicks back in your pants... god...

 

[TheKuudereDude]

Just a question, not much just a question. W-why is that one page colored?

 

[Alex-dono-sama]

to whoever colored that one page :
