Comparison of the two Hokage: Both ninja worlds are devastated.

Nagato, the Ninja World's Necromancer:

"Yes, yes, yes, Yahiko and Minami are right."

Jiraiya of the Ninja World:

"Is there no fairness or justice left in this world?" (in a fit of rage)

Minato Namikaze of the Ninja World:

"Yes, Uehara-kun is fairness and justice (laughs heartily)."

Jiraiya, suddenly and violently.

Chapter 156 Theory of Peace

Do you know the maximum lifespan of a person?

About half a month later,

In a newly built square courtyard,

Uehara Siming stood on the platform, looking down at the three little ones below, their faces solemn as if they were undergoing some extremely sacred ritual.

So he asked.

Because the three of them had been living a life of homelessness,

He often suffered from hunger and cold, and his physical condition was not very good.

Furthermore, as a fundamental skill for ninjas, chakra refinement cannot be achieved overnight.

Even geniuses need a certain amount of time to get used to that feeling.

For the past two weeks, Jiraiya has been helping them to improve their health and teaching them some basic things.

Meanwhile, Uehara Siming was not only having people build the courtyard, but also compiling teaching materials and organizing lesson plans.

Today marks the culmination of two weeks of intensive preparation.

The second major class on the first day of the official start of the semester was a class on peace theory.

The limit of human lifespan was the first question asked by Uehara Siming in his lecture.

As soon as he finished speaking,

Yahiko excitedly exclaimed, "I know that! It's fifty years old. There was an old lady in a town we lived in who lived to be fifty."

"She must have been around forty. That old woman might just be an isolated case. I know many people who died at the age of thirty."

Nagato squinted, his expression slightly uncertain.

In contrast, Xiao Nan was much more certain.

"How could it be forty years old? They say that's the limit. The one Yahiko knows might not be the longest-lived. I'd guess sixty."

With the question of Uehara Siming

Many people in the live chat also answered in response.

However, compared to the conservative nature of the three boys, they were a bit bolder.

Some guessed seventy, some guessed eighty, and some even said that there was a legend of someone living to be a hundred years old.

The correct answer is 120 to 150 years old.

I have a friend who likes to research strange and unusual things.

He discovered that cells in the human body undergo periodic renewal.

Almost every moment, aging or injured cells die.

Almost every moment, new, vibrant cells are being born.

Under conditions of sufficient nutrients and no special external factors, including both negative and positive influences,

The average lifespan of each cell is approximately 2.4 to 2.5 years.

The limit to how many times a cell can divide and regenerate is approximately fifty to sixty times.

2.4 times 50 equals 120 years old.

Taking the maximum of both, 2.5 multiplied by 60 equals 105 years.

Upon hearing this, the three little ones all showed expressions of disbelief and astonishment.

Yahiko was gesturing wildly, his face clearly saying, "Are you kidding me?"

Outside the window, Jiraiya's gaze flickered upon hearing this.

"The second question is, since the limit is that people can live to be 150 years old, do you know what the actual average lifespan of all people is?"

The three little ones shook their heads in unison.

Uehara Siming didn't keep them in suspense and gave the answer directly.

"Seventeen points six, if a person can successfully live to adulthood, that is, eighteen years old, he has already surpassed half of the people in the entire ninja world, and can be called long-lived."

Seventeen point six is ​​a figure from the period after the Ninja Village era; during the Warring States period, it was likely even smaller.

After all, the Warring States period was a time of constant conflict, with countless forces vying for power.

Even children were forced to take up arms and go to the battlefield.

During the ninja village era, although the intensity of war was even higher,

However, there will be a gap between the two wars.

During the truce, both the birth rate and the survival rate of the existing population will surge.

At this point, Uehara Siming paused slightly, giving the shocked group a moment to process their emotions.

After a few breaths, he continued:

"There are many factors that reduce the ideal lifespan of 150 years to a mere 18 years or less in reality."

This includes, but is not limited to, hunger, disease, fatigue, malnutrition, and unhealthy lifestyles.

Of these factors, the one that ranks first and far surpasses the second is war, which is also the topic we will discuss in today's lesson.

Uehara Siming turned around.

He broke off a piece of chalk and wrote the word "war" in large characters horizontally on the left side of the blackboard.

Then, he moved to the right and wrote "peace" in the opposite position.

The room fell completely silent for a moment.

Not only the three little ones, but also Jiraiya who was eavesdropping outside the window, and the two viewers in the ninja world watching the video, were inexplicably shocked.

"The damage caused by war is not only the killing of enemy ninjas on the battlefield,

These direct deaths account for less than one percent of the actual impact.

It would cause people in war zones to flee in droves, leaving vast tracts of fertile land barren and numerous factories idle or abandoned.

When these people reached a relatively peaceful area

Because they no longer had a means of making a living, they were forced to become thieves and bandits, thus causing wider unrest.

The end result will be further food production cuts and factory shutdowns.

People need to eat to survive, so new migrations and famine relief occurred once again.

This process will continue until there is no peaceful place left in the entire ninja world.

War also disrupts social order and hinders the flow of goods.

We know that the Land of Demons produces high-quality medicines, the Land of Lightning produces excellent beef, and the Land of Water has very plump and delicious fish and shrimp.

Normally, you can enjoy all of this as long as you have money.

But if war breaks out, it's not just a matter of being killed and robbed at any moment;

You will also find that almost everything, including medicines, food, and industrial output, will begin to be in short supply.

……

Alright, this concludes the first section of Chapter 1, "The Impact of War," in the first volume of the course on peace theory, "War and Peace."

"Ten-minute break, then prepare for the next class."

Uehara Shinmei once worked for the government for a period of time.

At first, he cherished this "iron rice bowl" job in the eyes of outsiders, and worked very hard and diligently.

Therefore, I learned a lot of useful knowledge.

Reportage, considered an essential skill for government officials, is one such example.

Based on their functions, they can be roughly divided into four types: reporting work, reflecting situations, making suggestions, and answering inquiries from higher authorities.

The content generally consists of six parts: title, overview, theoretical basis, research plan, expected goals, and condition analysis.

Regarding the enormous and complex topic of "war,"

He could talk for three days and three nights without repeating himself.

The entire course on peace theory encompasses much more than just war itself.

Uehara Siming's plan was like a political lesson from her previous life.

It incorporates a wide range of topics, including philosophical theories, cultural theories, views on life, values, legal concepts, principles of political economy, and a brief history of the ninja world.

Of course, some content will definitely be omitted.

I believe that once they finish learning these, they will be completely inspired by the new Will of Fire in Uehara's version.

In fact, I only listened to the first part of the first proposition.

Whether it was the three little ones or Jiraiya who was eavesdropping, their hearts were deeply moved.

It was as if I had finally seen a ray of light in the darkness.
