The situation of the Three Kingdoms of Northeast China is somewhat similar to the situation of the three kingdoms of Wei, Shu and Wu in the late Eastern Han Dynasty, where they all devoured the surrounding small princes and formed three larger forces. Among them, Goguryeo was the earliest and the most powerful, just like the strong Wei in the Three Kingdoms. Only by uniting together could Silla Baekje resist Goguryeo's strength.

In the face of the coalition forces of Silla Baekje, Goguryeo could not resist and allowed Silla to occupy the upper reaches of the Han River. Goguryeo also changed its tactics, no longer obsessed with unifying the Korean Peninsula, and looked to the west, Liaodong. Silla, Baekje, lost Goguryeo, a strong enemy, and began to fight among themselves, and the two sides fought fiercely around the lower reaches of the Han River.

When Luo Shixin went deep into Goguryeo to find Sun Simiao, he specially learned about the situation of the three countries of Korea. They attacked each other, which was understandable, as Luo Shixin expected, but it was not his expectation that little Japan also intervened.

As a time-traveler, there is no future generation who does not hate Japan.

"Japan, that is, Yamato country, their group of birdmen also participated in the war?" Luo Shixin is really not used to calling Yamato, there are many names in Japan, Fuso, Wa or something, until recent years they changed an orthodox name, calling themselves the country of the rising sun. However, most people don't buy their accounts, and the name Yamato is called the country, and the name Japan is also based on the country of the rising sun.

Li Yuncong bowed his head and said: "Yamato and Baekje are not far away, and the relationship is extremely close. Especially in recent years, the Sui and Tang dynasties got rid of the suffering of the chaotic wars between the northern and southern dynasties and developed rapidly. The economy and culture have risen substantially. They seem to have absorbed the Sui and Tang systems from Baekje and transferred them to domestic use. ”

"It is their bandit instinct to steal the strengths of other countries." Of course, Roth was disdainful in his faith. But we have to admit that Japan has done an excellent job in this regard. They are able to learn from the strengths of other countries without shame and turn them into their own, thus making themselves richer and stronger. They were able to absorb the Sui and Tang dynasties' policies from a small slave society to a feudal society, and they were able to absorb European science and technology, so as to develop the Meiji Restoration and improve their national strength, and become a scientific and technological power at that time, which is the best example.

Li Yuncong didn't know why Luo Shixin was so disgusted with Yamato. But he also had the same feeling, and continued: "It is too polite to say that the robbers scolded them and defiled the beasts." They sent troops to help Baekje attack Silla. With their strong combat effectiveness, they successively captured more than a dozen cities in Silla, but after capturing these cities, they burned all of them, leaving only Baekje with an empty shell. If it weren't for Silla's Kim Yeung-shin, he decisively gave up the lower reaches of the Han River. Well-thought-out deployment. Twenty fortifications were built along the line of the Han River, and the defenses of the lower reaches of the Han River were connected in one line, so that they could resist the coalition forces of Yamato and Baekje. Silla is now oppressed by Goguryeo and Baekje, and it is extremely difficult. My uncle felt that Silla was close to us, and if Silla was destroyed, it would not do us any good, but it would be a catastrophe, and I also had this trip to Chang'an. Came to the Tang Dynasty. Along the way, it was exactly as rumored. With a new atmosphere, it is like a world of difference from the Sui Dynasty in memory. "When he was in the army to conquer Goguryeo. The defeat period of the upright Sui Dynasty. The world is in danger because of terrible servitude, and there are voices of rebellion everywhere in the world. And now the Tang Dynasty is in ruins, the world is determined, and various policies to stabilize the people's hearts are also in place, which is indeed several times better than the Sui Dynasty at that time.

Luo Shixin chatted with Li Yuncong while eating, listening to him talk in detail about the situation on the Korean Peninsula in the three northeastern countries, but he was thinking about how to capture the greatest benefits for Datang.

The geographical location of the Korean Peninsula is not excellent, it is located in the middle of nowhere, and it has no real value except for Changbai Mountain, but it is located in the rear of the Tang Dynasty and has special strategic value. Otherwise, the Sui and Tang dynasties would not have worked hard for it, regardless of the treacherous expedition of thousands of miles.

Now the Tang Dynasty still has the intention of expeditioning to the Three Kingdoms in the Northeast, but as long as Liaodong is in the hands of Goguryeo for a day, the Tang Dynasty and Goguryeo will inevitably have a war. With the fighting style of the Tang Dynasty, if you want to fight, you should take the destruction of the country as the first purpose, and do not make small fights. However, the environment of Goguryeo is harsh, and it is indeed difficult to fight. Yang Guang's fate is a lesson from the past, Li Shimin also attacked in the future, although he achieved a lot of results, recaptured Liaodong, captured Goguryeo ten percent, broke tens of thousands of enemies, and finally chose to withdraw because the climate turned cold, the grass withered and frozen, and the grain and grass did not continue. In this battle, Li Shimin also realized that the environment of Goguryeo was harsh and could not be taken by force, so he changed his tactics and relied on the captured Liaodong, mainly to attack and harass the tired enemy, and consume the strength of Goguryeo. In the end, his son Gaozong Li Zhi relied on the good situation created by Li Shimin, relied on the conquest of Su Dingfang and Li Shiji, and then destroyed Goguryeo with the help of the power of Silla.

The more Silla needed the support of Datang, the more they were at the mercy of Datang, the worse their situation became, and the more they had to rely on Datang for Datang's use.

Presumably Zuo Tiancheng thought the same way, he wanted to avenge the four or five hundred thousand comrades-in-arms who were buried in Goguryeo and piled up to become a Beijing official. This is revenge, and the little Silla is obviously not able to count on it, and Datang is his only reliance. Letting Li Yuncong personally escort the Silla envoy to Tang was far from being as simple as protection, and it must have been for him to further understand the situation of the Three Kingdoms in the Northeast, so that he could make a reasonable judgment based on the clear Three Kingdoms.

"Where do you live now? I'll go to you when I have time, and by the way, I'll meet the princess of Silla. Luo Shixin thought about it for a while, and also made up his mind. The enemy of this enemy is the enemy, Goguryeo is the enemy of the Tang Dynasty, Baekje is in the same place as Little Japan, that is the enemy of his Luo Shixin, this is unreasonable and unreasonable, and those who should help still have to do something.

Li Yuncong saw that Luo Shixin had seen through his intentions, and said quite embarrassedly: "I live in the Chang'an Post House, we also met the envoy of Baekje in the post house, and the atmosphere between them is very stiff. I was afraid that they would be unfavorable to the princess, so I didn't dare to drink more with Brother Shixin. ”

Compared with Li Yuncong's embarrassment, Luo Shixin has seen a lot of talk here, and the relationship between people is indispensable when they need each other and stand on opposite sides. Li Yuncong thinks about their clansmen, Luo Shixin thinks about Datang, it is about their own positions with each other, and it is understandable that friends have different thoughts.

Li Yuncong has always been concerned about his own mission, but he drank happily with Luo Shixin, and returned to the post station to protect the princess of Silla.

**********

The moon is dark and the wind is high, and the day of murder and arson.

Chang'an Pawn Bureau.

Since Emperor Wu of the Han Dynasty played the great Han Tianwei, the number of foreign races in the court has gradually increased, so he has specially increased the Honglu Temple, an institution for entertaining foreign guests. This institution has been inherited, and the Tang Dynasty added the Pawn Office on the basis of the Honglu Temple, which was used to entertain envoys and important guests of other countries.

Datang is now in ruins, and what it needs most is not the Quartet to fight but to recuperate. Only by making friends with all parties and reaching a consensus on peace can we continue to develop steadily and lay the foundation for the future Quartet campaign.

The new emperor of the Tang Dynasty succeeded to the throne, and most of the foreign envoys who chose to come to the court at this moment had the intention of making friends with the Tang Dynasty.

In the Pawn Office there was a distinguished guest who was not an envoy of another country, but who was more important than an envoy of another country.

Yang Yan, a nobody, a pawn who enjoys the treatment of a third-grade adult.

You must know that the grade of the Tang Dynasty is different from the past, and most of the officials above the second rank are fictitious titles and have no actual power. Most of the people who really have the actual power are in the area of the third-rank officials, just like several prime ministers, and the left and right scholars shoot them as the third-rank officials. The treatment of the three rank officials is like the treatment of the prime minister, and even the envoys of other countries are not qualified for this treatment.

This makes a low-status blacksmith feel flattered.

Especially an honest person like Yang Yan who has never seen the world.

Yang Yan has lived in Ezhou, Jingnan since he was a child. Ezhou is a well-known steel town, and the iron ore production in the territory is abundant. There is a record in the Three Kingdoms period: in the "Ancient and Modern Sword Record", "Wu Wang Sun Quan used Huangwu to mine Wuchang copper and iron in five years, and made thousands of swords and ten thousand knives, each three feet nine inches long, and the head of the knife was square, all of which were made of southern copper and charcoal", until now, Ezhou is still a treasure land of iron ore production.

Ezhou is rich in iron ore, and their smelting level is one of the best in the entire Tang Dynasty.

Yang Yan is one of the blacksmith families, because steel is a state-owned resource, most of the steel is contracted by the state, these small blacksmiths can only rely on their luck in some abandoned iron mines or mines with little reserves to dig insufficient quality iron ore to meet the needs of the people. Yang Yan can make steel, and the craftsmanship is good, the quality of steel is better than the number of iron, it is very practical, and the supply exceeds demand. However, because of the insufficient supply of iron ore, this is in short supply, just because of low production, not a booming business, and a lot of money. Life is still very tight and has not improved because of it. Especially a few years ago, Yang Yan's old father was seriously ill, bedridden, paralyzed, and needed high expenses, and had to hire someone to take care of his daily life. At that time, it was a troubled time, and the situation was a little more serious.

Forced by life, Yang Yan began to think that if he used the little iron in his hand to smelt more steel, he would relieve the pressure.

The emperor lived up to his wishes, and with his efforts, he really let him improve the smelting method, successfully eliminated unnecessary losses, and made more steel from a fixed amount of iron.

Yang Yan's invention attracted the attention of the Ezhou Thorn History, and he went to the imperial court, but because Yang Gongren was pedantic, he didn't pay attention to these strange tricks, and ignored them, knowing the discovery of the eldest grandson Wuji.

Yang Yan knew that he would have to meet the emperor tomorrow, and as a small citizen, he couldn't sleep well because he was nervous. Flip through his smelting experience, so as not to make a typo when he handed it over to the emperor.

At this moment, a knife appeared on Yang Yan's neck and pulled it gently! (To be continued......)
