In fact, the earliest record of the malicious exchange between Goryeo and the Central Plains Dynasty should be Emperor Yang of Sui's three expeditions to Goryeo. Pen ~ fun ~ pavilion www.biquge.info

And as far as Huang Jie saw in his strange dream, at least in the heavenly opportunities he glimpsed, the fall of at least three dynasties in China was directly related to Korea.

If it weren't for Emperor Yang Guang of the Sui Dynasty and his three expeditions to Goguryeo, the rule of the Sui Dynasty would likely have lasted for dozens to hundreds of years; If it weren't for the Wanli Emperor who fought to the point of financial bankruptcy to "resist Japan and aid Korea", the Ming Dynasty might not have let the Manchu Nurhachi family pick peaches so easily; If the Qing Dynasty had not been defeated in the First Sino-Japanese War, the glamorous Westernization Movement might have been able to fool the world for decades.

Of course, there was another "War to Resist US Aggression and Aid Korea", which was said to save the "Republic of China", but the final outcome of the dream was not conclusive.

However, the most puzzling thing among them is why Emperor Yang of Sui unswervingly went to Goguryeo, and even changed his original intention even until the country was ruined.

For later generations, Emperor Yang of Sui's move is often interpreted as irrational madness, or it is nothing more than a great feat, reckless military force, anyway, even the explanation of "protecting the family and defending the country" is untenable.

From the perspective of Chinese history, it may be unique to attribute the launching of such a large-scale war to the "madness" of a certain faint monarch.

However, it is very easy to puncture this point of view by calling Huang Jie, even if Emperor Yang of Sui is a faint monarch, then Emperor Wen of Sui Yang Jian and Tang Taizong Li Shimin are not, but these two "holy monarch" level emperors have not only fought Goguryeo, but the funniest thing is that they have not won either.

Then, it is obvious that the "Goguryeo problem" that spanned two dynasties and four generations of emperors (Emperor Wen of Sui, Emperor Yang of Sui, Emperor Taizong of Tang, and Emperor Gaozong of Tang) did not hesitate to solve it by war, must not be explained simply and rudely by "madness".

At the beginning of the Song Dynasty, after Kou Zhun made the alliance of the Yuanyuan, he believed that if the Great Song Dynasty could not overthrow the Khitan Liao State, there would be no need to strengthen the control of the territory of the Northwest Party members, and forward-looking pointed out the military idea that "if the Party wants to establish Liao", it will break the Liao.

In fact, according to Kou Zhun's train of thought, the party members later established the Western Xia, although they also learned from the Liao State to the Great Song Dynasty to fight the grass valley, but in fact, they have always taken the Liao State as an example of learning and transcendence, thinking that the Great Song Dynasty is a lamb to be slaughtered, but the ownership is in the hands of the Liao State, and only after the Liao State can they eat mutton justifiably.

As a result, the party members have been poor for several generations, and they have always been making trouble and stumbling for the Liao State, even if there are rare cattle like Li Yuanhao, but in the end they still failed to overturn the Liao State and became a disease of scabies.

Similarly, the emerging Jurchens also regarded the Liao State as a mountain that needed to be crossed, and in fact, it was indeed the world that overturned the Liao State as a thoroughfare. Therefore, at this time, if we look back, it is not difficult to find why the four generations of great emperors across the two dynasties have been trying to conquer Goguryeo, which is commonly said: in their opinion, if they do not conquer Goguryeo, they cannot be regarded as truly unifying the world.

Just like the remnants of the Western Xia people's idea of "if you don't fight the Liao State, you won't be counted as having the right to invade the Great Song Dynasty", and the Jin people did "If you want to win the Great Song Dynasty, you must first break the Khitan".

However, for this issue, it seems that whether it is the Goguryeo people before, the later Silla, Baekje, and the current Goryeo, they seem, should, maybe, and may never have studied it, and the only thing they studied was what was when Tang Taizong Li Shimin personally conquered Goryeo, he was shot blind in one eye by the Goguryeo general Yuangai Suwen and became the one-eyed dragon emperor.

Having said that, all of the above is just a boring caprice for a while after Huang Jie watched the fifteen rounds of vehicle-mounted bed crossbow launches, and the question he thought about at first was why from Emperor Yang of Sui to Emperor Gaozong of Tang, they all came to fight Goguryeo and lost, and then it also extended to why they came to fight Goguryeo. And in the end, the conclusion he came to extended to his previous discussion with the seed master Dao: "If you want to break the Jurchen, take Goryeo first." If you want to get Goryeo, you must take Incheon", but now he finds that he seems to be thinking about the problem for granted, as far as the current situation is concerned, why take Incheon?

That's right! Why take Incheon, he got on the ship from Lijia Port in Cheongju, landed from Nampo with a swagger, and then came to Xijing with a swagger, and now he swaggered and defeated the Goryeo general Cui Zhuo in a battle with zero casualties, and for the height of the city wall in front of him is only more than two zhang, the defenders in the city are at most 50,000, and the people are at most 150,000 Goryeo Xijing, Huang Jie secretly calculated, based on the standard bomb volume of fifteen heavy guns, to collapse the city gate at most 300 ammunition, If you want to make some more openings in the city wall, you can count 100 more rounds per hole in the wall!

Regarding the remnants of this place in Incheon, Huang Jie thought that he was affected by strange dreams.

The reason why people in later generations fancy Incheon is because the iron-hulled hull of later generations is heavy and the draft is too deep, so they have to choose a natural deep-water port like Incheon to land.

Today, the Thousand Grain Civilian Ships of the Great Song Dynasty are about 17 meters long, 6.5 meters wide, 6.5 meters high, and the draft is about 2.5-3 meters. The official ship is about 27 meters long, 8 meters wide, 5-6 meters high, and the draft is extremely shallow, just over 2 meters.

As for the military strength of the Great Song Dynasty and Goryeo, there is no comparison, although the two dynasties live next to each other, but the performance of today's Goryeo general Cui Zhuo proves that they not only do not know what the latest chariot arms of the Great Song Dynasty are, but even the Great Song Dynasty has a bed crossbow with a range of more than 1,000 steps.

Otherwise, how could it not be seen why the Song army was arrayed nine hundred steps away from the city, that is, three arrows away, obviously not knowing that the distance of nine hundred steps was exactly the target area of the best range for the bed crossbow to fire the one shot and three sword arrows of Mu Gan Tieling.

A parabolic shot from the bed crossbow with three swords and arrows, after flying in the distance of 600 to 900 paces, and gaining gravitational acceleration in the process of natural fall, was the most powerful and fierce when it pierced in this position.

To tell the truth, when Cui Zhuo led 5,000 men and horses to the front of the city, Huang Jie really felt a little incredible, and then thought that there was no military exchange between the Great Song Dynasty and Goryeo, and Goryeo had pursued a policy of closing the country to the outside world, but he had planted the roots for his own defeat.

All in all, after watching the fifteen textbook-like demonstrations of the car-bed crossbow rapid fire, Huang Jie stood on the command building car and began to think about the question of what was no longer to protect overseas Chinese and try to dig into the corners of Goryeo, but whether it was possible to make a bigger plan!
