People who follow Hirota Narakawa do not need to have too many tasks. They just need to know who Hirota Narakawa met and where these people went. Although the entire Hakata City is under the control of the Tang Dynasty soldiers, it is impossible for the city to completely prohibit these people from entering and leaving. There are not many Japanese in this era.

Just like Hakata City, although it is the largest port in Japan, the population of the entire Hakata City is only about 100,000. If it is the largest port in the Tang Dynasty, the estimated population is at least 300,000.

You can find out by referring to several important port cities located on the Yangtze River in the Tang Dynasty.

This is because Hakata Castle is indeed the most important port in Japan. According to Huo Gang's estimate, the population of the entire country is about 2 million, or even less than 2 million. Referring to later generations around the Ming Dynasty, that is, the Warring States Period of Japan, the approximately population was less than 8 million.

At that time, due to the development of Japanese technology and various aspects of technology, Japan's social population could increase steadily. At this time, Japan's first reform has not been completely completed, so the population of Japan during this period was definitely not large. Japan completed its first feudal social reform in the Tang Dynasty, and it was constantly sending people to learn from the Tang Dynasty and reformed it after it was reformed.

But it was not now, but Emperor Kodeok, who was in the late Zhenguan period, proposed reforms, and the current Japanese emperor had not completed the reforms at all.

Therefore, the total population of Japan during this period was less than 2 million.

According to this population ratio, it is not even as large as the entire Chang'an population. The population of the two counties in Chang'an is close to one million, and in the future it will exceed one million.

Li Tai naturally knew this data, and he also knew it from Huo Gang. It is actually not difficult to calculate the approximate population of a country in this era based on some data statistics.

It is probably based on the grain cultivation situation in this country, and then the approximate number of grain acres, etc., to infer how many people can be raised. Therefore, it is not difficult for Li Tai to win Japan during this period.

Based on the population of 2 million, half of the men are counted as one-third of the young and middle-aged people, which means there are only more than 300,000 young and middle-aged people.

How many young and middle-aged people who have more than 300,000 people can actually join the army? In total, there is not even a hundred thousand people. The Emperor of Japan cannot gather a hundred thousand troops.

But if the Tang Dynasty wanted to, it could easily pull out an army of 100,000 people and completely sweep the entire Japan.

Of course, the total war between the two countries is different from now. First of all, logistics is a huge problem, because if you don’t want to have no way to rule later, you must treat ordinary people better.

If it is better, then the food will not be able to rob the food of ordinary people. If the army of 100,000 people is supported by sea transportation, it will consume a lot, because sea transportation also requires the transportation of other logistics supplies.

For the Tang Dynasty, it was really not worth the loss, and it was really not as good as Li Tai's previous plan. According to Li Tai's plan, it would probably take only four or five years to counterattack.

At that time, there was no need for the Tang Dynasty army.

After Nagawa Hakata left the city lord's mansion, he hesitated for a moment, and finally, as Li Tai said, he immediately conveyed various orders, first of all, to stabilize the situation in Hakata Castle.

"Of course I know that the Tang Dynasty has become stronger, and it seems that there is a more powerful country. Not to mention anything else, the train that is as long as an iron dragon is too powerful. It is not something we can make." Langchuan nodded straightforwardly.

Japan has always had a large number of envoys sent to Tang and Sui in Chang'an City, so the news of the Tang Dynasty is not unfamiliar to Japan. As the main window for communication with the Tang Dynasty, Hakata, the owner of Hakata Port, was naturally very clear about these things.

"Yes, in the past ten years, the national strength of the Tang Dynasty has expanded at least several times. The most powerful enemy around the Tang Dynasty was originally the Turks, but now the Turks have been completely eliminated. The Western Turks have been replaced by the Han Dynasty. The powerful Han Dynasty has little influence on us. Because the Han Dynasty and the Tang Dynasty came from the same source, it is said that the emperor of the Han Dynasty personally led the army to save His Majesty Li Shimin of the Tang Dynasty from the hands of Jie Li of the Eastern Turks."

"The two countries have almost become brother countries, which means that the Tang Dynasty's army on the west side can almost be drawn back to most, and the Han Dynasty exported a large amount of grain to the Tang Dynasty every year, so the Tang Dynasty's Western Regions were not short of food. According to some of our news, after the Tang Dynasty annexed the Eastern Turks, it did not just enthrone some Eastern Turks' Khans as vassals and asked them to pay tribute."

"But it is directly located at important locations such as Wuyuan and the foot of Yinshan Mountain outside Yanmen Pass, such as Wuyuan and Yanmen Pass, to station troops and open up land. A large number of Eastern Turkic herdsmen migrated to the territory of the Tang Dynasty, and a large number of Tang people migrated outside the Great Wall to live with the Turks. They also promoted Chinese, learned Chinese dialect, learned Chinese characters, followed the etiquette of the Tang Dynasty, and related laws and regulations were exactly the same as those of the Tang Dynasty."

"Master, can you tell why this is?" Fujino asked as he looked at Hakata Narakawa.

"The Tang Dynasty wanted to permanently stabilize the outside world, but did not want history to repeat itself. After decades, these nomadic peoples once again became the main threat to the Tang Dynasty." Nagano thought for a moment and said directly.

"Not bad! This is what the Tang Dynasty thinks now. If the Turks in these places were like the Tang people after decades, at that time, even if the Tang Dynasty's rule over here weakened, these people who were almost indistinguishable from the Tang people would have reduced their harm to the Tang Dynasty to the limit."

"More importantly, if the train can be built all the way to the location where the Turks are, then this place will definitely become the territory of the Tang Dynasty forever."

"Under such a situation, master, have you not noticed that the Tang Dynasty has become more and more tough in the surrounding small countries in recent years?" Fujino spoke seriously.

"What do you mean?" A dense layer of cold sweat appeared behind Hirota Narakawa. Fujino's words were terrifying to think about it carefully! Hirota Narakawa could become the leader of the Hakata clan, so naturally he would not be a mediocre person, but he had never thought so before. When Fujino said this, he instantly reacted.

"We don't know at the moment, but we can't rule out this possibility. Master, a very simple question. Think about it, did the pirates who plundered the coastal villages of the Tang Dynasty only appear today? No, as far as I know, since the Sui Dynasty, pirates have been constantly plaguing the coastal fishing villages of the Central Plains dynasty, but these dynasties have no good solutions, let alone directly engage in evil with island countries like us."
