Ranbu Naruto nocturnal volume

Never underestimate the existence of tools like waterwheels!Waterwheels have made great contributions to agricultural development.It greatly alleviates the constraints on cultivated land terrain.

Realize the development of hilly and hilly land.It is not only used to draw water during drought, but can also be used to drain water when water accumulates in low places. As an agricultural building, it is deeply loved by farmers.

Due to the author's influence, the terrain of the Naruto manga is mountainous and hilly, but there are relatively few large plains where humans can gather and live.

Due to the background of a large-scale war-torn environment and the existence of a Chakra energy system, an energy system that is beyond the times, the overall social development of the Naruto world is extremely uneven, and there are huge flaws in the underlying agricultural technology.

It’s okay if no one promotes it. Li Yunlong opened his mouth to promote the advanced technology of water wheel. The rich people in the Naruto world are not fools. They will naturally notice the impact that water wheel brings to agricultural production. Huge convenience.

You must know that the development of waterwheels in our country has not been smooth sailing, and its development history has lasted for a long time.

The earliest folk utensil for drawing water should be the "Jujue". "Zhuangzi."External chapter."Heaven and Earth Chapter" records that Zigong traveled to the south. When he passed Hanyin on his way back, he saw an old father-in-law working hard to carry water in an urn for irrigation, doing half the work for twice the time.

So he told the old man a labor-saving device called "槔".The way it is made is: "Hew wood to make a machine. The back is heavy and the front is light. The water is like pumping, and the number is like a fertile soup." 』

That is to say, a crossbar is used to support the wooden frame, with a wooden bucket for drawing water hung on one end and a heavy object hung on the other end, like a lever, which can save the power of drawing water.

The waterwheel appeared in official national written records around the Eastern Han Dynasty.

At the end of the Eastern Han Dynasty, during the reign of Emperor Ling, Bi Lan was ordered to build a "turnover cart", which already had basic devices such as wheel axle groove plates.There is also a saying that during the Three Kingdoms period, the Wei people and horses also had "rollovers" (see the notes of Du Chuan and Pei Song in Volume [-] of "Three Kingdoms. Wei Zhi").

Regardless of who actually created the "waterwheel", in short, the official emergence of "waterwheel" from the Eastern Han Dynasty to the Three Kingdoms can be regarded as the first stage of the establishment of the waterwheel.

The development of waterwheels reached the Tang and Song Dynasties, and great progress was made in the application of wheel and axle. It could use water power as power and made a "cylinder wheel". With the pool and connecting tube, it could send low water to high water.

Not only is it more effective, but it also saves valuable manpower.Zhang Xiaoxiang of the Southern Song Dynasty praised him highly in his "Poem on the Wall of Nengren Courtyard" and said: "Turn this poem to save you from the suffering of the drought." 』

It can be seen that this water wheel is of great help to farming.This is the second stage of the development of waterwheels.

In the Yuan and Ming Dynasties, the development of wheel axles became more advanced.A waterwheel has not only one set of gears, but as many as three sets.

In this way, it is technically possible to achieve "water-turn overturning", "ox-turning overturning" or "donkey-turning overturning", which can be used interactively according to the wind and soil.

This development enables more efficient use of rollovers.Since its invention in the Eastern Han Dynasty and the Three Kingdoms era, rollover has been stagnant in the operation of human power.

It was not until the Yuan and Ming Dynasties that people realized the use of water power and animal power for driving, finally liberating human power from the turning pedal.

At the same time, due to the development of rotating shafts, vertical wheels, horizontal wheels, etc., the barrel carts that were originally driven only by water power could make use of animal power even in places with less abundant water, and made a contribution.

In addition, there is the emergence of "high-rotating drum vehicles".In places where the terrain is steep and it is impossible to open a pond, water can be sent low and high, and some development can be achieved.

This is the third stage of the development of waterwheels.After the Yuan and Ming Dynasties until the founding of the People's Republic of China, the development of private waterwheels did not have many special achievements.

In other words, if a tool like a waterwheel develops freely among the people, it will take a long time, even a long time measured in thousands of years, to mature.

Now Li Yunlong suddenly put the already developed waterwheel technology into his book "Ancient Eastern Countries", with detailed illustrations and clear text, and clearly put it there.

From the perspective of technology patents, this technology alone far exceeds the price of the entire book "The Ancient Kingdoms of the East". People who buy the book are making huge profits!

Li Yunlong's "Ancient Oriental Kingdoms" series has more than fifty books. Naturally, it cannot be supported by waterwheel technology alone. Li Yunlong then released the agricultural plowing technology, using water driven by water to turn the machine to grind!

Water-to-machine mill is also called water mill for short!This simple machine that uses the natural power of the water flow in the river to convert it into mechanical power to drive the semi-automatic operation of the huge stone mill is a big killer in the agricultural society!

People have long known that food is always good, but large-scale processing of crops is not a labor-saving job!

Therefore, it’s not that the people at the bottom don’t want to eat well, but they lack enough time and energy to conduct preliminary processing of agricultural products.

Although the water-to-machine mill has a simple structure, it can use water power to liberate manpower, and it can be used for a long time with only one investment, which is enough to bring great convenience to an entire village!

This is the remarkable result that technological progress can bring!

Li Yunlong refused to give up, and incorporated a large number of carpenter and fitter skills into the book in sequence, from the production of basic tools and measuring tools to simple calculation and composition knowledge, and even included a complete palace composition and simple manual machine tools.

Taking into account the rich natural resources in the Naruto world, Li Yunlong also added simple primitive mineral search technology, shallow surface mine tunnel excavation technology, and indigenous smelting technology.

These technologies have already touched upon the core content of the military industry in the world of Naruto. Strictly speaking, it is not an exaggeration to classify them as important weapons of the country!

At this point, Li Yunlong was still unwilling to be satisfied, and extended his claws to the "Barefoot Doctor's Manual".

What is the most widely circulated book in the world?Some say it’s the Bible, some say it’s the Encyclopedia Britannica…

But among the medical book series, "The Barefoot Doctor's Handbook" is undoubtedly No. 1!

From 1969 AD, it continued to be printed, and until 1985 AD, it stopped being revised. According to statistics, more than one million copies have been printed.

For more than 30 years, many families in our country have prepared a "Barefoot Doctor's Handbook" at home to deal with family members who are sick.

"The Barefoot Doctor's Handbook" is full of pictures and texts. It is a "general medical medicine" guide, from common coughs and vomiting to complex cardiovascular and cerebrovascular diseases and cancer.

From disease prevention knowledge on killing mosquitoes and flies to protection against nuclear and biochemical weapons, from acupuncture and herbal medicine to commonly used Western medicine, everything is covered.The whole book pursues the principles of clarity, simplicity, and practicality.

"The Barefoot Doctor's Handbook" does not follow the traditional approach of starting with anatomy, physiology, biochemistry, and pharmacology. Instead, it is problem-centered and provides clear and simple treatment. Therefore, it has become a successful case in medical education.

Of course, the acupuncture techniques and medical prescriptions in "The Barefoot Doctor's Manual" cannot be directly applied to the world of Naruto.

However, with the knowledge Li Yunlong has mastered, it is not difficult to translate the technology into the world of Naruto based on ready-made cases.

At most, it will waste some time in the experimental process, but Li Yunlong has a plug-in computing unit in his hand, and he can save a lot of time by arranging experiments rationally with huge computing power.

Before the book is completed, Misako Hinata wants to set off a huge wave of popularity in the world of Naruto and it cannot be done in a day or two.

Li Yunlong has enough time to make detailed preparations, and there is no need to rush.

Li Yunlong's hope is that readers who can read through the "Ancient Eastern Kingdoms" series of books will have corresponding medical knowledge.

Then after a period of practice, you can use the medical techniques learned from the "Ancient Eastern Kingdoms" series of books to achieve the purpose of treating most diseases with a silver needle and a handful of herbal medicines.

The book "The Ancient Kingdom of the East" contains a large number of beautifully printed and detailed patterns, as well as Li Yunlong's deliberately mixed technology, which should be enough to cause a sensation in the entire Naruto world!

However, since these technologies do not involve the chakra power system and ninjutsu, the "Ancient Kingdoms of the East" series of books has a wide range and great influence.

In a short period of time, it is difficult to have a huge impact on the entire ninja world!

Therefore, the second book "Heroes of Konoha" set by Li Yunlong is aimed at the entire ninja world!

The whole book "Heroes of Konoha" follows a purely cool writing routine, and the protagonist's name is Konoha Heroes Maru!

Most of the protagonist's age, personality, appearance, and background settings were copied from Uzumaki Naruto.

Of course, the place where the protagonist lives is Konoha Ninja Village, and many characters in the Ninja Village also use real names and images.

However, the names of most of the characters and supporting actors in the book were made up by Li Yunlong.

The real Konoha high-ranking Li Yunlong only focuses on two characters, namely Sarutobi Hiruzen, the third generation Hokage of Konoha Ninja Village, and Shimura Danzo, the actual leader of the roots of Konoha Ninja Village!

In the book "Heroes of Konoha", the third generation Hokage of Konoha Ninja Village, Hiruzen Sarutobi, was deliberately portrayed by Li Yunlong as an incompetent man who was greedy for power!

A layman in foreign wars, an expert in civil wars aside, the third Hokage, Sarutobi Hiruzen, still has major flaws in his character.

Although he tries hard to portray himself as a kind-hearted person on the surface, he talks about the will of fire all day long!

In fact, the Third Hokage Sarutobi Hiruzen is a big bad guy who easily listens to slander and uses all kinds of despicable means to secretly harm the ninjas of Konoha Ninja Village!

In Li Yunlong's depiction, Danzo Shimura is even more conspiring with the Third Hokage Sarutobi Hiruzen!

Not only is he more greedy for power than the Third Hokage Sarutobi Hiruzen, he is also shamelessly willing to be the third Hokage Sarutobi Hiruzen's eagle dog!

As long as the Third Hokage Sarutobi Hiruzen winks, Shimura Danzo and the root ninjas he leads will not hesitate to do all kinds of shocking and immoral things!

Especially when harming the own ninjas of Konoha Ninja Village for no reason, all kinds of insidious and despicable methods emerge in endlessly!

As for the third generation Hokage Sarutobi Hiruzen of Konoha Ninja Village and the actual ruler Shimura Danzo of the Roots, are they really such people?

Li Yunlong doesn't care!
