The third part of "The Divide of Regional Cultures and Ethnic Groups" is called "Empirical Evidence", which is the most valuable chapter of the book, and the author conducts a field investigation to reach the conclusions of the second part.

Considering that era, and considering the author's aristocratic status, as a nobleman, it was very rare in that era to be willing to inquire and investigate the lower classes in such detail, although the author still retained some aristocratic arrogance in the investigation, but the flaws were not hidden.

At that time, the people who wrote the paper were not as standardized as later generations, and in the author's "empirical", the investigation data was presented in the chronological order of the author's investigation, rather than the same type of people, which made it difficult for later generations to read this paragraph, but it also allowed people to infer the order of the author's investigation from the order of "empirical".

From the "empirical evidence", it can be confirmed that the author conducted a survey in the early years of the Middle-earth Forest Colony on the Edonan Peninsula, and provided information on the local North Poutu and Poly people, as well as some Bourbon confessions who came to trade here.

The next information that appeared was the Polis from Poly itself, the Bourbons who were merchants, the ancient Bourbons, the Pokans, and the author even went to the border to investigate some Bonnes, which is the only source in the entire 16th century that personally spoke to the Bonnes, which is very valuable.

The source of the re-emergent material is the Lower Edonan Peninsula, where the author surveyed the local South Boutu, Edonan, Poly, and even the Bourbon people in the southern Boris colony. However, the fly in the ointment is that these sources are all from the coastal zone, and the author did not go deep into the Edonan country to investigate.

After leaving the Lower Edonan Peninsula, the author first went to the Dumo Liao Transit in Boris, where he conducted his investigations, and then went to the capital of Boris, and visited the Napolica Palace and Hades Square, where he even painted a picture, as the author says in the general preface.

After Boris, the author did not go to Portlou, but went north to Bourbon, where the author did not mention his theory of "ancient Bourbons", so he had a good time.

Speaking of this, it is impossible not to mention an anecdote, according to the accounts of later visitors, in the monument erected to him by the "sage" Solit after the death of Luhr, the eulogy is introduced in a joking tone that when the concept of "ancient Bourbons" was proposed, several Bourbon residents traveled thousands of miles to Hechu and threw rotten eggs at the author.

"The Sage" Solit said triumphantly in the monument, "It is precisely because my father's theory is correct that the ancient Bourbon, unable to accept the facts, had to try to ignore the truth by slandering the flesh."

The post-Bourbon material is from Pokang, where the author has put a lot of effort into it, he has been to the border to explore the Bonnes on the border of Pokang, and he was almost taken captive by the Bonnes.

The author is very interested in how the concept of the Pokang people was born, and he is the first scholar to systematically study this system by digging deep into the former "Bokang chieftain-Bourbon aristocratic representative system", which is still very important and indispensable for understanding the evolution of the Pokang people.

According to the general preface, after the completion of Bokang's investigation, the author returned to Hechu and began to organize the materials of his investigation, which was finally assembled into a book, which was published in 1677 in the first edition of "The Distinction between Regional Cultures and Ethnic Groups".

The fly in the ointment of the first edition is that the author has very little investigation of the Boehmis and the Boemi, he has only seen some Boeaux merchants in Boris and Bourbon, and the author himself has not personally investigated the Boemi, and his information on the Boehmis is all from the introduction of the Boemis.

So the place where the Portrus and Boemi are introduced at the end of the third part of the first edition is very unreliable. And the fourth part is also very simple, and the author mixes the lost people with the other races of the Bourbon Sea in this part, and there is a lot of hearsay in it.

However, the author has an advantage, every time he cites an argument, he will always write down the origin of this argument in detail, and many books that have been lost today can be found out of context through his first edition, so the first edition of "The Distinction between Regional Culture and Ethnic Groups" is also of historical value.

Not being able to go to the Tenglong Continent has always been a heart problem of the author, and in the general preface, the author said, "I am already sixty or seventy years old, and I don't have to leave my homeland to go to the war-torn land. His words are reasonable, but the matter has come to this, and there is only one book in his life, if he gives up at this time, he will be unwilling after all. After thinking about it for three months, I finally made up my mind and left Hechu. ”

There is a sentence worth noting in the article, "You don't have to leave your homeland to go to a war-torn place", which is related to the international environment at that time.

The Edonan Peninsula, and even the island of Bourbon, were once a region of fire, but in the author's time, the war was long away from his homeland.

The most recent war on Bourbon Island was the Bourbon War, which lasted for 15 years from 1561 to 1576, which ended forty years before the author's birth and did not reach the forest guard at all, so the author has no impression of this war.

The most recent war on the Edonan Peninsula was the Third Edonan War, which lasted 14 years from 1606 to 1620, which ended when the author was 10 years old, and the main battlefield was always on the Lower Edonan Peninsula, separated by a strait from the Upper Edonan Peninsula, where the forest guard was located.

After the end of the Third Edonan War, there was no war on either the Edonan Peninsula or Bourbon Island, and it was peaceful, and the next war of Willis was in 1684, when the author's life was only 8 years.

In addition, the author's active era, whether it was Polly or the author's forest guard, both relied on the Laventica trade to make a lot of money, and the most serious conflict that broke out during this period was the trade war between Polly and Boris in 1652, but it was far from the point of fighting each other.

Therefore, in ancient times when wars were frequent, the author was called a lucky man of peace, and almost all his life was spent in peace, which was the object of the desire of countless people in troubled times.

So in the 16th century, peace and trade were the main theme of the Edonan Peninsula and the Bourbons, and war was far from here, but this was not the case for the west coast of the Tenglong continent, and the author fearfully called it the "land of war", which is completely true.

The period from 1632 to 1639 lasted for seven years and took place during the Subak War between Indoland and Portlou.

The war lasted for 13 years from 1633 to 1646, when the civil war between the Three Lords of Ulchi led to the military invasion of Potlu and Maisica, triggering the Second War of the Three Lords.

The civil war that lasted for 12 years from 1658 to 1670 was known as the Reform War due to the "Inner Governance" (abolishing the Inner Kingdom and establishing a guard office).

The period from 1661 to 1667 lasted for six years, during which the Maisica nobles overthrew the New Delian dynasty in a civil war, the Anti-Delian War.

The 14-year period from 1674 to 1688 was a war between the oligarchs of Potruw and Ulch that was triggered by the civil war in Maischa, in which only mercenaries were sent and no official war was declared.

Why did the Laventica trade quickly overwhelm the long-standing Brayazon trade? Because in the 16th century, wars broke out one after another throughout the continent of Tenglong, and after entering the 17th century, not only did not weaken, but quickly evolved into a war between the four great powers.

The long and continuous war disrupted the original old trade projects of the Tenglong Continent, which allowed the Laventica trade to emerge and quickly seize the original market. And it is precisely because the Tenglong Continent is fighting that the author can enjoy "the peace of our time".

When the author prepares to go to Portlou, although Portlou has not declared war, he has supported an oligarch and is sending mercenaries to Maishika to join the melee, which is not very peaceful, which is why others advised the author not to go to Portlou now.

However, it can also be seen from the general preface that the author insisted on going, and after arriving in Portlough, he was warmly welcomed by the local nobles, who granted the author the right to view the library.

It's a pity that the author is completely old at this time, so this time the Portlou trip was not able to go to the bottom to investigate the information in person as in the past, and the information written by the author was provided by the Portlough faction.

This is the reason for the controversy between the proponents of the first and complete editions of the book, who sharply criticized the complete edition, arguing that the extensive deletion of the original Portrue material in the complete edition was not a matter of filling in the gaps, but rather a revision of the material that the Portruws deemed appropriate, so the historical value of this part is very low.

During the Portlou trip, the author first went to Adasi to comment on the restoration after the "Epposian Incident", then went to Olly, the capital of Portlou, and finally went to West Isaacs to see the monuments (where the "Navigator" Lull landed on the Myramie Peninsula).

After browsing these three places, the author went home, and in the middle of the weather, his body was weak, and he rested for a while in the middle of Dumo Liao.

After returning to Hechu, the author lamented in the general preface, "The body is getting weaker and weaker, and the time of death is not far away, and I can't go to the lower level like in the past, which is deeply regrettable." ”

The author then spent more than a year revising the manuscript to establish the final edition of The Divisions of Regional Cultures and Ethnic Groups, and then published this step in 1686.

At the end of the general preface, the author says so.

When the book was finally written, I felt a lot of emotion in private, and thousands of words accumulated in my chest, and I didn't know how to confide it. Looking at the rough waves on the coast, I still remember the detailed conversation with the Laventica people Fensu under the moon, and it took more than 30 years. Life is like a wave in the sea, fleeting, if you rely on this book and the northern country, you can leave a small name in future generations, it is also fortunate. ”

"Writing a book is fun, a few pens, I don't know what to do. Recalling his life, peace is a top priority, but two years ago, Pokang actually started a border provocation and started a war with Bourbon, and the 60-year peace of Bourbon Island was lost. The juniors were ignorant and thought that this was a temporary situation, and after the war, they naturally returned to normalcy. ”

"However, the god of the sea once said that the initiator has no future, and when the provocation is opened, who has the ability to save the sky? I am afraid that the flames of war will burn all over the Bourbon sea!"

At that time, the author Lul Sauds set another precedent before his death, predicting the imminent outbreak of a terrible war that would engulf the entire Bourbon Sea, and after the death of Lul Schats, countless people made predictions and warnings, fearing the imminent imminence of this war.

Their prophecy was helplessly correct, but their attempts to prevent it were doomed to futile, and the war between the Bourbon Sea nations was destined to grow larger and wider until the end of the Bourbon Sea War.

The outbreak of the Willis War in 1684 was only a precursor to a new round of war between Bourbon and the Edonan Peninsula.
