Here’s the extracted text from the image: “Rules: Bath supplies, warm cloth and ointment are surprising; within the area of a hot spring: within the components, it is now made easily, and since it flows smoothly for the construction of the remedy, even our side does not heal easily when used by others. The cloth and warm medicine from Edo are also produced and used, along with thermal agents that easily penetrate warmth: observation: effectiveness is confirmed, and rigorously synthesized products are prepared. The history shows that the hot cloth was actually applied and stamped on soft skin-colored materials for treatment, making use of various substances; created with intention, the various components of people are produced as “named bundles of willow,” for cutting grass, and both products feature soft characteristics for installation: crafting works under renovations and beginning lectures on thermal materials for self-heat. It is said that professional materials are combined carefully.”

1: Japan Otaku Reviews

It looks like gelatin is easily coming out, but the method of gathering it seems difficult.

2: Japan Otaku ReviewsYeahx13

It seems difficult, but the doctors of old must have done something similar.

6: Japan Otaku ReviewsYeahx18

>>2

I’ve heard that about half of it is now treatment due to the placebo effect with no actual effect, but it’s amazing that there are also excellent formulas for medicine that are scientifically proven.

32: Japan Otaku ReviewsYeahx1

>>6

In this era, it’s not just half, but almost all.

Even in the mid-Edo period’s pharmacology, it was at a level that resembled traditional Chinese medicine.

Around that time, Western learning would gradually begin to enter.

3: Japan Otaku ReviewsYeahx12

Gelatin is basically glue.

4: Japan Otaku Reviews

Isn’t your knowledge amazing!?

11: Japan Otaku Reviews

>>4

Isn’t it great? I was a doctor in my past life, you know?

12: Japan Otaku Reviews

>>4

Oh knowledge

Overflowing knowledge

25: Japan Otaku ReviewsYeahx1

>>4

Before my reincarnation, I was a doctor with perfect memory, so I can recall even the detailed stories from textbooks and games!

27: Japan Otaku ReviewsYeahx1

>>25

However, there is a restriction that it can only include textbooks from the compulsory education range and knowledge limited to medical universities, so it can lead to an unlimited amount of claims.

30: Japan Otaku ReviewsYeahx1

>>27

I think herbal medicine is related to the School of Pharmacy.

48: Japan Otaku Reviews

>>4

Where?

5: Japan Otaku ReviewsYeahx1

Gelatin is obtained from deer.

7: Japan Otaku ReviewsYeahx9

Gelatin can be extracted by boiling animals.

8: Japan Otaku Reviews

Now that affordable medicated patches are widely available, the spread of technology is remarkable.

9: Japan Otaku Reviews

I don’t know when, but Japan didn’t raise many pigs during the Edo period, and cattle were regional, so gathering gelatin must have been quite difficult, right?

16: Japan Otaku Reviews

>>9

Let’s hunt! Wild boar!

10: Japan Otaku Reviews

Gelatin is a substance formed by the coagulation of protein juice, so fish jelly would be fine too.

13: Japan Otaku Reviews

Was it there from the very beginning… mint?

21: Japan Otaku Reviews

>>13

I don’t know about mint, but if it’s Japanese peppermint…

The high content of L-menthol in peppermint led to active exports until synthetic peppermint from petroleum became mainstream.

24: Japan Otaku ReviewsYeahx3

>>13

If it’s Wakka, it was already there in the Heian period.

14: Japan Otaku Reviews

Modern people may feel that the healing power of pain relief patches is just… well, about this much, but if they’ve never used them before, they might feel a significant effect.

15: Japan Otaku Reviews

It’s really amazing! A doctor!

17: Japan Otaku Reviews

I saw someone with a bun for the first time instead of a messy haircut.

18: Japan Otaku ReviewsYeahx6

I think the most amazing thing about this is that it’s not the latest technology, but rather the technology that already existed from the Edo to Meiji periods.

Was there such an excellent thing in such an era…?

19: Japan Otaku Reviews

Even without the anti-inflammatory effects of salicylic acid, as long as it can provide some cooling and has a mint scent, it seems that would be enough to feel the effects at that time.

20: Japan Otaku Reviews

You can find quite a few herbal remedies in Japan without specifically going to Sakai or Hakata.

You can find quite a few herbal remedies in Japan without specifically going to Sakai or Hakata.

Due to the fact that Tamato fell ill during the review, permission was granted based on that. Additionally, in this report, I asked for the procurement. Ah… this is from Arkra, right? Job’s tears… The quality is somewhat poor, but it has been obtained. Great wind child, huh? I also managed to secure some parts of Mint?! Licorice for the throat and cough relief. Actually, for insecticide, it’s sprout production. Great wind seed, other medicines for changing herb properties. Job’s tears for nasal toxins and swelling. Sprouts (aloe) for fire toxins, hair loss, desalinization. Gout and expectorant. Peppermint (English herb) for eye purification and insecticidal properties. Cranjil for sunstroke, longevity disease, and hoshi malaria.

22: Japan Otaku Reviews

A man who releases gelatin from his penis.

23: Japan Otaku Reviews

At that time, I casually collected data by applying a patch to only one side of the injured area to see which one would recover.

26: Japan Otaku Reviews

Having a sense of hygiene and knowledge about it in the future will significantly reduce the number of deaths, right?

Specifically, hand washing and gargling.

Well, whether such clean water can be consistently secured is uncertain.

29: Japan Otaku Reviews

I mean, the range of knowledge is like that of a traditional Chinese medicine doctor, right?

In modern times, I suppose it must be desirable to only be popular with grandpa and grandma.

33: Japan Otaku Reviews

Even though the knowledge from the game is there, because history has collapsed, about 80% of what happens in which era has vanished early on.

36: Japan Otaku Reviews

>>34

If you don’t prepare some different criteria, you’ll get criticized endlessly for that.

In other words, you’re trying to stir things up like that, aren’t you?

37: Japan Otaku Reviews

>>34

This isn’t an original manga; there was an original work.

45: Japan Otaku Reviews

>>37

It’s the type that has been adapted into a manga because it was completed and highly rated.

40: Japan Otaku ReviewsYeahx4

It’s a pitiful little fly that mistakenly rushed in, thinking this was a thread for bashing Narou.

41: Japan Otaku ReviewsYeahx1

There are a lot of reincarnations in the Warring States period, but having vague knowledge like Ken is relatively uncommon.

Is it at the level where even enthusiasts know about this? There are local skirmishes and powerful warlords that come up, right?

47: Japan Otaku ReviewsYeahx1

>>41

In this work, since it starts about 20 years before the mainstream era of Nobunaga, there are quite a few lesser-known generals, and the protagonist can also feel quite unfamiliar.

As expected, Asakura Sōtaku knew.

42: Japan Otaku ReviewsYeahx2

Well, compared to Ken, who remembers just about everything related to cooking, it’s not so bad…

43: Japan Otaku Reviews

Even though it’s just a half-baked skill, my Go abilities are still holding up…

49: Japan Otaku ReviewsYeahx2

>>43

The refinement of established techniques due to the accumulation of history is simply on another level…

53: Japan Otaku ReviewsYeahx1

>>43

In modern Japan, a level of Amateur Dan 3 would have been quite strong several hundred years ago, don’t you think?

44: Japan Otaku ReviewsYeahx1

I think it’s unfair because the textbook range really varies and often there are parts that we don’t actually cover in class.

46: Japan Otaku ReviewsYeahx5

Works like this are basically premised on history enthusiasts showing off their knowledge while enjoying discussions, so this is just fine.

50: Japan Otaku Reviews

Since mass production is impossible anyway, I’m thinking to just use bladders instead of rubber where it’s needed.

51: Japan Otaku ReviewsYeahx1

Ken forcibly connects niche information to history…

52: Japan Otaku Reviews

Well, I’m tired of the same old story of making money through shiitake mushroom cultivation and sake brewing.

I can’t just do it so easily.

54: Japan Otaku ReviewsYeahx4

>>52

I won’t do either…

55: Japan Otaku Reviews

>>52

Should I do a boost with an egg in the tempura…?

56: Japan Otaku Reviews

>>52

Over here, the main products are the increased production of paper, soap, and glass products.

57: Japan Otaku Reviews

Glass is a delicate material, so it seems difficult even with knowledge.

63: Japan Otaku Reviews

>>57

In reality, there were a lot of failures, but if the failures are beautiful, they have value just for that reason, so they could be used as gifts.

65: Japan Otaku Reviews

>>63

No, because there is a lot of lead, it won’t look nice before the shape even matters.

76: Japan Otaku Reviews

>>65

Why do you know about lead glass but not soda glass?

58: Japan Otaku Reviews

I think paper and soap are more common.

59: Japan Otaku Reviews

Soap can be profitable, but more than that, I am working on establishing a future-friendly relationship by purchasing seaweed from Oda.

I was pointed out by my father that it might not be good in Ise.

60: Japan Otaku Reviews

They used to put raw beef or horse meat on bruises in “Hyouge Mono.”

I understood that cooling is important.

61: Japan Otaku ReviewsYeahx1

>>60

It is well known that horse meat has high efficacy.

64: Japan Otaku Reviews

You have to take the age of the characters into account.

Actually, there are stories that it was a pioneer, but by the time of the comic adaptation, it seems to have become somewhat worn out.

66: Japan Otaku Reviews

First of all, Japan’s glass production has surprisingly become a lost technology, so it was necessary to research from scratch, but it turned out to be profitable.

We can properly source the materials in Japan too.

67: Japan Otaku Reviews

There are limitations due to the technology and environmental factors of the time, but let’s do what we can within those boundaries.

68: Japan Otaku Reviews

Form is based on experience, so it gets refined to the extent that it can be sold in stores, but the quality that depends on the materials cannot be helped.

69: Japan Otaku Reviews

Isn’t it amazing that swords made from low-quality Japanese steel have been elevated to artistic masterpieces?

74: Japan Otaku Reviews

>>69

Over here, in the early and middle stages, it’s all about guns, the Frankish cannon, and cavalry units; swords hardly appear at all…

In the final phase, we use searchlights and balloon-mounted megaphones to illuminate and observe the hidden opponent before blowing them away with shells.

70: Japan Otaku Reviews

When I dug up my textbook in a while thanks to this manga, I realized I was just dim-witted, but it actually has a lot of detailed knowledge from compulsory education.

The text mentions methods for manufacturing rubber and suggests that it seems to anticipate even the aftermath of a nuclear war.

71: Japan Otaku Reviews

>>70

It’s knowledge that you wouldn’t use unless it’s after the decline of civilization or in some other reincarnation…

72: Japan Otaku Reviews

Well, that’s because it was imported.

73: Japan Otaku Reviews

I like this work, but the part where they do doctor-like things is only at the beginning.

75: Japan Otaku Reviews

>>73

The historical part was stronger and was quite different from what I expected.

77: Japan Otaku Reviews

In the medical field, we do ordinary work, but instead of focusing on specific cures when we get sick, we strive in areas like vaccinations and hygiene to eliminate the factors that lead to illness, so it’s natural that the medical-related aspects will decrease.

It’s too late once you get sick! I know that’s true, but…

86: Japan Otaku Reviews

>>77

If necessary, I will carry out the surgery without fear of exposing my identity, so if I want to, I can involve as many patients as I want.

It will be like a gin.

78: Japan Otaku Reviews

Are we starting a thread about this manga again?

79: Japan Otaku Reviews

The glaze cannot be treated as glass.

The art university teacher said that it’s probably a ratio that can’t be used for soda glass, but I don’t know the details, and I can’t figure it out even when I search.

80: Japan Otaku ReviewsYeahx1

I want to take a look at something like another world reincarnation JIN.

81: Japan Otaku Reviews

Even if we try to gather herbs with modern knowledge,

It seems that because the names are completely different in the regions, something entirely different might show up.

83: Japan Otaku Reviews

>>81

So we have to search for substitutes by experimenting with similar products and complete it.

Bondage play

82: Japan Otaku Reviews

The raw material for gelatin, or glue, in the Edo period was fish.

Using the word “nibe,” which has become a common phrase, in a blunt manner.

84: Japan Otaku Reviews

Have you been able to mass-produce rubber?

87: Japan Otaku Reviews

>>84

To be honest, I really don’t understand why I’m looking for a rubber.

If it’s about molding a unique item, it might be manageable, but when it comes to mass production, won’t we need to utilize other technology trees as well?

89: Japan Otaku Reviews

>>87

Because it’s convenient…

90: Japan Otaku Reviews

>>87

Because the properties of rubber are unique.

Rubber is still used in various ways today, including its properties of being solid, elastic, having the ability to return to its original shape, and being sturdy and inexpensive to mass-produce.

91: Japan Otaku Reviews

>>90

Modern technology makes mass production possible at a low cost, doesn’t it?

If it’s just the nature, the internal organs can be used.

88: Japan Otaku Reviews

>>84

I think I’ll start making the factis soon because it’s impossible.

Still, I complain that this will break right away.

85: Japan Otaku Reviews

I have the impression that glue can spoil quickly if not dried, but is it okay to stick it on my skin?

92: Japan Otaku Reviews

Let’s collect dandelions and make something like rubber.

93: Japan Otaku Reviews

It's a type of potash glass that goes a step further than soda glass in terms of manufacturing. It is a remarkable material that is harder and more transparent than other glass, and it is commonly found in painted glasses seen in Western antiques.

Sprinkled sand, wood ash, lime. The sprinkled sand was used in the kiln, so I took some and mixed it with wood ash and lime. Before it cools, shape it while blowing on it to complete. Since it becomes gooey, attach it to a stick with holes and heat it in a high-temperature kiln.

It’s a type of potash glass that goes a step further than soda glass in terms of manufacturing.

It is a remarkable material that is harder and more transparent than other glass, and it is commonly found in painted glasses seen in Western antiques.

98: Japan Otaku Reviews

>>93

Did you also add something to the material?

Of course, it can become beautiful.

103: Japan Otaku Reviews

>>98

Isn’t “glass” that doesn’t alter the material just quartz glass?

102: Japan Otaku Reviews

>>93

I guess many people must have died in the accident…

94: Japan Otaku Reviews

This original work has been revised many times, and since I am a technical historian who orders all the textbooks to relearn, it’s natural that it is heavily focused on the technical aspects.

97: Japan Otaku Reviews

>>94

Even though it’s a bondage play, the range you can use keeps expanding endlessly!

95: Japan Otaku Reviews

Rubber is useful for tires, cushioning materials, and even contraception.

104: Japan Otaku Reviews

>>95

It seems that a fish’s swim bladder was a reusable contraceptive with elasticity similar to rubber!

Is it really okay to use it repeatedly…? Isn’t it dirty…?

96: Japan Otaku Reviews

It seems that filling a bladder with air and covering it with leather could turn it into a rugby ball, so it could be used for things like tires.

99: Japan Otaku Reviews

Rubber was originally planted in places like the Philippines and Indonesia much later, so I was wondering what to do, but I was impressed that they managed to procure something similar called gutta-percha, which is also found in Okinawa and originates from Southeast Asia!

100: Japan Otaku Reviews

Without a smartphone or the internet, I think you would need almost complete memory abilities to pull off knowledge cheating.

101: Japan Otaku Reviews

Rubber is simply convenient for preventing malfunctions, so if I could, I would want to make it.

As long as you have the rubber tree itself, you can gather low-quality materials from Mino for everything else.

In the first place, rubber only became available in modern times, so we compromise with poorly made substitute rubber, but in the end, the yield is poor and we suffer.

105: Japan Otaku Reviews

The complete memory ability was useful in this way! Rather than saying, “Why do you know that knowledge…?” it’s just that the setting is made so that readers don’t say that, so there aren’t many scenes that say how great the memory ability is.

106: Japan Otaku Reviews
111: Japan Otaku Reviews

>>106

It’s a material that’s much easier to make than lead glass, but historically, even the original Bohemia hasn’t been able to develop this future technology yet…

107: Japan Otaku Reviews

Couldn’t we have a better name than “crappy carrot”?

112: Japan Otaku Reviews

>>107

It may sound like a silly name, but it’s truly a great herb that changed history, you damn ginseng.

108: Japan Otaku Reviews

It’s the same with Dr. Stone, but if you’re seriously going to do science from scratch, you won’t get anywhere without knowledge cheats.

In today’s world, everyone usually focuses only on their specialized skills.

109: Japan Otaku Reviews

>>108

Even with knowledge, human effort is underestimated too much…

110: Japan Otaku Reviews

Knowledge is one thing, but technicians…

113: Japan Otaku Reviews

A technology tree that, thanks to a miraculously exceptional precision creation, allows for the mass production of highly accurate items based on it, involves an element of luck as well.

114: Japan Otaku Reviews

Going to the Sengoku period with complete memory ability seems really tough…

125: Japan Otaku Reviews

>>114

What I realized first when I was reincarnated and remembered my previous life was…

“My reincarnation destination has a father who is dangerous, and I am also someone who will eventually die from illness.”

It’s actually a story where knowing just enough leads to various struggles.

115: Japan Otaku Reviews

Speaking of which, I wonder if glass technology was no longer a secret around this time.

The history of glass has been quite bloody, hasn’t it?

118: Japan Otaku Reviews

>>115

It was supposed to be a normal secret…

Stories about the glass guilds in Italy

121: Japan Otaku Reviews

>>115

It’s still the secret tradition era, but craftsmen are occasionally escaping and spreading out.

116: Japan Otaku Reviews

It can be the most enjoyable time when you’re managing things in challenging circumstances.

117: Japan Otaku Reviews

Probably the episode where I suffered the most in the story.

Probably the episode where I suffered the most in the story.

119: Japan Otaku Reviews

“The past has low-quality everything in terms of baths, meals, and living conditions— QOL.”

Just that can make you depressed.

120: Japan Otaku Reviews

I think my head itches so badly that I could die, but I was okay…

122: Japan Otaku Reviews

It has been quite an ordeal to reach the current treatment, as there’s been a lot of trial and error, including applying poop and putting medicine on the weapon instead of the affected area.

123: Japan Otaku Reviews

The human body has many phenomena with low reproducibility due to individual differences.

124: Japan Otaku Reviews

The butterfly effect is amazing, but the missionaries are taking a long time to arrive.

Even guns haven’t been introduced in manga yet.

126: Japan Otaku ReviewsYeahx1

>>62

In occult terms, the soul possesses all experiences and abilities… that’s why.

Isn’t it fine since reincarnation is the premise?
