For Kumiko Takahashi and others, although Li You didn't pay special attention, he still had some impressions. Kumiko Takahashi's pale face and the skin of her white jade-like neck form a strong contrast. This aroused Li You's curiosity.

Just as I passed by Miko Takahashi, a faint fragrance came from her body, and this fragrance was extremely weak in the strong aroma of various drinks and dishes in the sake shop.

However, Li You has a dog nose and a keen sense of smell is one of the biggest characteristics of a foodie, so this faint fragrance is still captured by him. There are many beauties around him, and it can be seen that the fragrance of this woman is somewhat special, and it should not be commonly used by women in the Tang Dynasty.

Li You returned to his table and sat down in the place where the white tiger had been sitting before, which was more convenient for him to observe the movements of Kumiko Takahashi and the others.

The living habits of the Japanese slaves are very different from those of the Tang Dynasty, even if they are dressed up as Tang Dynasty people, if you look closely, you can still tell the difference.

For example, the people of the Tang Dynasty nodded their heads down a little and immediately returned to their original positions, while the people of the Japanese slave country nodded down by a large margin and stayed for a long time. Also, although the people of the Tang Dynasty also attached great importance to etiquette, the concept of respect and humility was not so strong, and the people did not need to kneel when they saw officials, and they were not so respectful. The Japanese slaves are different, their hierarchical and inferior systems are extremely strict, and the demeanor of people of different status is very different when they speak, etc., if you compare them carefully, you will find many differences.

After Li You said this, everyone suddenly realized. However, everyone still deeply admired Li You's meticulous observation.

Dengzhou was a port and commercial city, and there were originally many Japanese slave activities. Since the emergence of a large number of pirates, the Japanese slaves have been discriminated against and ostracized in the local area, and everyone has left Dengzhou except for those who are related to the local community by marriage.

In this context, Kumiko Takahashi and others pretended to be Tang Dynasty people and stayed here, and their appearance was very suspicious. Li You had people call Sima Wang Huairen of Dengzhou and inform him of the situation.

As the supreme governor in charge of public security in Dengzhou City, Wang Huairen was ashamed and said: "Your Highness, the minister is very ashamed that he did not fulfill his duties. Please punish Your Highness. ”

Li You said: "Lord Wang, you don't have to blame yourself, it is normal for one or two hidden Japanese slaves to appear in such a big Dengzhou. Liu Renliang and they have captured a lot of pirates, you arrange for someone to take them to quietly identify them, and try to find out the identities of those Japanese slaves. Don't alarm them just yet. ”

Zhang Guigui said: "Brother You, what are you doing so hard? Wouldn't you know everything if you were directly arrested in the first trial? ”

Li You said: "Don't worry, it's still useful to keep them." Since the pirates are fighting a spy war with us, let's put them to good use. ”

In the evening of the next day, Sima Wang Huairen of Dengzhou came to report on the investigation of the two men and one woman. He said: "Your Highness, the minister has quietly identified the pirates captured by General Liu, that woman is called Takahashi Kumiko, and she is the young lady of the Takahashi family in Kyushu. This Takahashi family is the largest family on Kyushu Island, and the patriarch is called Takahashi Kazuki, who occupies 30% of the land on Kyushu Island. ”

Li You was a little puzzled, this was a bit different from what he guessed was related to the royal family of the Japanese slave country, and he said: "Could it be that the whole pirate incident is just the work of this one family?" ”

Cheng Yanjin said: "Your Highness, this is impossible, didn't Wang Guoxiang of the Dengzhou Navy Division say that in the naval battle they fought at that time, the pirates had 500 warships, and it was impossible for his family to do it." He had been to Baekje and had seen Baekje's warships, so there should have been Baekje people involved. ”

Li You said: "Su Guogong, you are right, let's still follow the established policy." However, since there is an extra Kumiko Takahashi, this matter is easier to handle. ”

Cheng Yanjin smiled: "You want her to pass on the news to you, right?" ”

Li You smiled: "Uncle Cheng, everyone says that the two of us are very similar, and we are both stingy." Actually, they don't know you're really smart. ”

Cheng Yanjin smiled: "They fart, they are not stingy." Your Highness, when you praise me, are you praising yourself? Ha ha. ”

"Hahaha", Li You also laughed proudly.

In fact, this campaign to conquer the Japanese slave state was the beginning of a complete and complex plan, which Li Shimin had long wanted to implement, and his ultimate goal was Goguryeo.

For the Tang Dynasty, the real threat to the northeastern frontier was Goguryeo.

Goguryeo was founded in 37 BC when Jumong, a member of the Buyeo royal family, founded a small state in the northern part of present-day Heilongjiang, which grew in strength. In the Central Plains, when you led the dynasty to be established, they all hated Goguryeo very much, and as long as the conditions permitted, they would be requisitioned.

Goguryeo is one of the most capricious states in history, and all the central dynasties have surrendered and rebelled. When the Central Plains Dynasty was strong, they always used all kinds of means to take advantage of the internal contradictions of the Central Plains Dynasty to bribe the ministers of the imperial court in order to achieve the purpose of submitting to the Central Plains Dynasty.

Once the Central Plains Dynasty declined, they would immediately take advantage of the fire to rob them. It can be said that the Central Plains Dynasty of all dynasties has been calculated by them, so the Central Plains Dynasty hated them deeply, and sent troops to recruit them, wanting to destroy them.

However, the Goguryeo people are only a small strong man who can not be killed, and their vitality is extremely tenacious, they are not only strong in combat, but also take advantage of the contradictions within the Central Plains Dynasty, they can always turn danger into a disaster, and continue to grow and develop in adversity.

In history, only the Cao Wei regime once captured their capital, Marudu, and temporarily destroyed Goguryeo. However, less than 70 years later, they rebuilt Maruto Castle and grew again.

By the time of Emperor Yang of the Sui Dynasty, Goguryeo had developed into a powerful state with a population of millions spanning Liaodong and the western part of the Korean Peninsula, and they rebelled against the Sui Dynasty again, conquering large swaths of Sui territory in southeastern Liaodong.

Emperor Yang of the Sui Dynasty had a short temper and mobilized the forces of the whole Sui Dynasty to fight to the death against Goguryeo, which not only failed to kill Goguryeo, but also led to the demise of the Sui Dynasty.

At the beginning of the founding of the Tang Dynasty, Goguryeo established a vassal relationship with the Tang Dynasty and expanded in the northeast region, and when the Tang Dynasty was invaded by the Eastern Turks, they immediately rebelled and echoed the Eastern Turks. After the fall of the Eastern Turks, Goguryeo had developed very strongly, and did not take the Tang Dynasty seriously at all, and conflicts on the border with the Tang Dynasty occurred from time to time.

Li Shimin must destroy Goguryeo, he attacked Goguryeo three times in history, and in the end he did not achieve victory, and died with regret, his last words, confessed that Li Zhi continued to attack Goguryeo, and finally with the help of Wu Zetian, he finally destroyed Goguryeo.

Li You carefully studied the reasons for Li Shimin's failure to attack Goguryeo and found one of the most important reasons.
