However, the current Goguryeo is no longer comparable to the backward and weak Yuzi Joseon of the past. Feng Hong finally lost his head and gave Goguryeo tens of thousands of households from the Central Plains in vain, which also increased the population of Goguryeo during the period of King Changshou to 90,000 households.

Feng An's grandfather, who was sent to the Southern Dynasty, thus became a member of the Nanpiao clan, and was eventually sent to Lingnan to join the barbarians, but Goguryeo also took this opportunity to annex the entire Liaodong Peninsula.

King Jangshou was well aware of the strength of the Northern Wei Dynasty and did not have the impulse to compete with the nascent Northern Wei regime, but continued to clean up Baekje in the south, and after a long war seized the most important area of the Han River valley in Baekje, Baekje's power retreated to the coastal areas, and since then it has become the weakest of the three countries on the Korean Peninsula.

After the death of King Jangshou, this round of expansion of Goguryeo came to an end, and in this expansion, Goguryeo achieved great success, taking advantage of the great chaos in the Central Plains, seizing the entire Liaodong Peninsula in one fell swoop, and also controlling the Han River valley on the Korean Peninsula to the south, becoming an undisputed great power in the northeast.

At that time, the Central Plains, both the Southern and Northern Dynasties, sent envoys to Goguryeo, recognizing their right to rule Liaodong and the Korean Peninsula.

It is a pity that there is no flower for a hundred days, and after the longevity of the king, several Goguryeo kings were incompetent, and the country later fell into civil strife, and even Baekje and Silla, who were nominally subservient to Goguryeo, began to act and formed an alliance to deal with Goguryeo together. Recaptured the Han River basin.

But this process is equivalent to the Korean version of the Romance of the Three Kingdoms. Baekje contributed the most in the war. As a result, the Han River basin fell into the hands of Silla instead.

Baekje couldn't swallow this breath, so the Shinbai alliance broke down, and the three kingdoms fought each other for many years, and in general, Goguryeo was still the strongest pole of the three Koreans, occupying a vast area north of Sasu and east of Liaosu. Even the powerful nomadic Khitan and Jin Ya (the predecessor of the Jurchens, Yinbeji) were all slave tribes of Goguryeo, and they had to send troops to help in the war when there was a war.

Until the tenth year of the opening of the emperor, Goguryeo's infant Yang King Gao Yuan succeeded to the throne, this person is now the king of Goryeo, since the establishment of the Sui Dynasty, the successive Goguryeo kings have continued to pursue a policy of obedience to the Sui Dynasty, the annual tribute envoy has never been broken, and the friendly relations between the two countries have lasted until the Sui Dynasty opened the ninth year of the war to destroy Chen.

When Gao Yuan, the king of Yingyang, first succeeded to the throne, he witnessed how vulnerable the powerful Nan Chen was under the attack of the Sui army on all fronts. Quickly collapsed. His heart was greatly shaken, and he began to accumulate food and grass. Expand the army to prepare to resist the invasion of the Sui army, and the envoys sent by the Sui Dynasty to visit Goguryeo were arranged by the Goguryeo people in empty buildings, not allowing them to go to the streets to inspect the customs of Goguryeo, and guarded like thieves, and hurriedly sent the envoys back every time they finished handing over the national credentials.

Not only that, two months ago, Goguryeo's border generals launched a tentative attack on Yingzhou (the area around western Liaoning) of the Sui Dynasty, although this attack was easily repelled by Yingzhou Assassin Shi Wei Shichong (the former governor of Nanning Prefecture, who was also a master who had two brushes in battle, but liked to plunder with troops), but Goguryeo dared to cross the country and take the initiative to attack the Sui Dynasty, but it was the first time in hundreds of years.

Wang Shichong said this, and gradually understood in his heart that Goguryeo was afraid that he had also heard the rumors that the Sui Dynasty was about to fight a full-scale war with the Turks, and throughout the history of this country, it has always taken advantage of the civil strife in the Central Plains or the war with the nomadic empire in the north, and when it was unable to divide its troops to look eastward, it took the opportunity to encroach on the territory outside the Shanhai Pass, and this time it seems that it is trying to repeat the old trick again.

Yang Jian should have seen Goguryeo's ambition from this seemingly ordinary border conflict, and was determined to clean up this small northeastern power before the decisive battle with the Turks, so that it would not dare to fight any crooked thoughts in the war with the Turks.

Yang Jian kept stroking his beard while listening, and Gao Xi and the others also had a flickering light in their eyes, and it could be seen that they were also using this opportunity to speculate on Yang Jian's thoughts, and after Wang Shichong finished speaking, Yang Jian nodded: "Wang Yuanwai, do you know how strong Goguryeo is now?" ”

Wang Shichong quickly calculated in his heart and said: "The 90,000 households in the period of King Gaolian of longevity are their population nearly two hundred years ago, and Goguryeo has occupied the Liaodong Peninsula for two hundred years, and has seized the Han River Valley, and there has been no large-scale war or famine in the country.

I heard that the current population of Goguryeo should be four or five hundred thousand households, which is comparable to a large state in our country, and there are no less than 100,000 people with armor. ”

Yang Jian turned to Gao Xi: "Gao Servant Shot, based on the information you inquired about, is what Wang Yuanwai said accurate?" ”

Gao Xi looked serious and said: "Your Majesty, not only that, starting from Yingzhou in western Liaoning, crossing Liaoshui, out of Liucheng, passing through the White Wolf Fortress, entering the hinterland of Goguryeo, until the city of Liaodong, there are more than a thousand miles, basically there are no roads, all in the wilderness, if it is in the rainy season, it will become a large area of Zeguo, and there will be a big problem with logistics supply. It is necessary to conquer with an army of 300,000, and there will be a big problem with the supply of logistics, so it is better to coerce the king of Goguryeo to send an envoy to be a vassal, and not to use the sword lightly. ”

A trace of displeasure flashed on Yang Jian's face, and he was about to speak, but Yang Su said loudly: "The minister thinks that there seems to be something wrong with Gao Fu's opinion, and Goguryeo must be taught a hard lesson." ”

Yang Jian said "oh": "Aiqing, please tell me the reason." ”

Yang Su said unhurriedly: "In the final analysis, it is still a matter of lifestyle, the nomads on the grassland are born after water and grass, unless they want to enter the Central Plains, otherwise they occupy the cultivated land of the Han people, and they cannot be used for grazing, and they have to return at the end." Even if they want to enter the Central Plains, they will be like the original Xianbei people, and will eventually be assimilated by our Han people.

On the other hand, it is difficult for us Han people to occupy the grasslands in the north, also because of the way of life, even if we build cities and open up fields as Changsun Sheng has always proposed, and push the Great Wall out of the desert step by step, it will take hundreds of years of continuous operation, which is not so easy.

So to deal with the steppe wolves in the north, in fact, now this kind of razing to control razing and support the leaders who listen to us. This kind of restraint strategy is the best and the least costly

But Goguryeo is different, they also use the system of the Central Plains, based on farming.

Your Majesty, Wang Yuanwai said very well just now, as long as there is a mess in the Central Plains, they will take the opportunity to encroach on the Han land, unlike the steppe wolves, who rob the population and then retreat to the desert, they not only want people, but also land, and this is how the land of Liaodong is gradually swallowed by them.

Therefore, for us Han people, whether it is the Xiongnu, Xianbei or Turkic, they are all controllable ringworm problems, and this Goguryeo wants to fight steadily and destroy the great trouble of our Chinese henchmen in one fell swoop, and they must not be allowed to develop.

Even if we have today's Han family, it was only slowly developed from the Central Plains, Henan and Guanzhong, from Xia to Zhou, thousands of years of time to constantly annex the surrounding weak tribes, and integrate them, so that we have become such a big country today.

This time their attack on Liaoxi was a temptation, and the timing was also just when our dynasty was preparing for a big war against the Turks. If our response is weak now, or if it is defeated by the Turks in the future, then Goguryeo is likely to really raise a large army and take the opportunity to seize the land of Liaoxi. Once Yingzhou is lost, Goguryeo will have a large number of immigrants to this place, as it did with Liaodong, and it will be difficult for our dynasty to recapture it. (To be continued......)
