The task of this unit is to be responsible for the defense of the capital, as well as the defense of Zhang San and other important officials, so they have always been excellent soldiers as Praetorian Guards, and advanced weapons Praetorian Guards are tried first.

With the establishment of the Jin Dynasty, Wanyan Aguta wiped out the 700,000 army of the Liao State, and the Jin State attracted a large number of tribes to surrender, so now the Jin State has more than 90,000 Jurchen cavalry and more than 30,000 vassal soldiers of other ethnic groups.

As soon as the snow melted in the spring, Wanyan Agu couldn't wait to launch a war against Goryeo, this time Wanyan Agu sent 50,000 Jurchen cavalry and 30,000 vassals, known as 100,000 troops, intending to make Goryeo surrender in one fell swoop.

And after a winter of mobilization, now the whole of Goryeo is also ready to meet the Jurchens, and learned the lesson of the last time the capital was almost breached, this time Wanyan Agu put 20,000 Jurchen cavalry and 10,000 vassal infantry in Liaoyang. And with 20,000 cavalry to patrol the border of Liao.

For Zhang San, this battle is also very important, in order to boost the morale of Goryeo and other three countries, Zhang San also specially approved a batch of grenades and fire oil bombs for defending the city, Zhang San believed that the Jurchens would definitely hit their heads in Goryeo this time and break the bloodstream.

The bad news is that I don't know who passed the new siege method that appeared in the Great Song Dynasty to the Jurchens, and the Jurchens have now begun to use explosives to attack the city, and the source of the explosives turned out to be bought from the Liao State.

This is really a pig teammate, no wonder the Liao Kingdom died, and even this kind of thing is resold by someone! What's even more bizarre is that the Jurchens also established their own firearms troops, although there are only 2,000 people, but the muskets are indeed the foreign trade version of Zhang San.

Zhang San was powerless to complain about this, and after the oath of the Jin State, he quietly set off, trying to catch Goryeo by surprise, but the Jin State had not yet reached the border, and the whole Goryeo knew about it.

After Yan Agu crossed the river, he quickly surrounded a small city on the border of Goryeo, but it took a day to fight down, and after the fight, his face was black, and the other party only had a thousand people, and he killed 3,000 troops, the key is that this is still a small city!

The subsequent war was as Ah Guda guessed, not only were the cities difficult to fight, but also the villages along the way were empty, and he had encountered a strong wall and a clear field, for the Jurchens who had no logistics, this tactic was fatal.

In desperation, Aguta had no choice but to divide the army into four parts and expand the scope of robbery, hoping to gain something, which was the same as the general staff's deduction, 80,000 people were divided into four, and some of them were only more than 10,000 people.

Then the Three Kingdoms of Goryeo began to formulate their own plans for encirclement and annihilation, because Zhang San had promised them that if any of them could destroy more than 10,000 Jurchen cavalry, then they would be equipped with Qi's own muskets and artillery.

For Zhang San, these guns have no value in transformation, anyway, they are to be sold, it is better to use them to attract these people to work harder, in short, for Zhang San, it is good to lose both sides, or to suffer heavy losses on the one hand, it is all beneficial to Zhang San.

The first to fight was Goryeo, after all, there was a geographical advantage and numerical advantage, the Goryeo people organized an army of 80,000 and successfully surrounded this Jurchen cavalry, Goryeo originally thought that 80,000 against 10,000 was not yet 9 out of 10?

Because Goryeo also fought with the Jurchens before, although Goryeo has always been at a disadvantage, the difference between the two sides is not very big, and Goryeo feels that after being equipped with firearms, the current Goryeo is no longer the Goryeo of the past.

But they forgot that the current Jurchens are not the Jurchens of the past, so the result was that 80,000 people besieged less than 20,000, and as a result, they also let the family run away by 8,000, and finally counted that they died more than 15,000 before killing the other party's 7,000 horsemen.

However, the good news is that with the consumption of other cities, Goryeo first achieved the task of 10,000 people, and the northern and southern Wa kingdoms only sent 30,000 troops this time, so they could not engage in encirclement and annihilation tactics like Goryeo, but learned the method of Qi to lure the enemy into fighting street battles with the Jurchens, so the two Jurchen cavalry were deceived into two cities respectively.

After a fierce battle, each lost four or five thousand people and retreated, and when Aguda received the news, the troops on the other three sides had lost a lot, and hurriedly concentrated the troops, and as a result, when this division of troops was counted, 20,000 troops were gone, and the Jurchen's own cavalry had lost more than 10,000 since the beginning of the battle.

This loss is not a toothache for Ah Guta, but a heartache, the heart is dripping blood, there are few of them, this battle is fought to this extent, and Ah Guda is also really hot.

However, Aguta is also a genius of war, and he feels that since the main force of Goryeo is on the border, he decides to take all his troops to surround Seoul, use his secret weapon, and prepare to break through Seoul and capture the king of Goryeo alive.

The so-called secret weapon of the Jurchens was the explosives obtained from the Liao State, and when Wanyan Aguta led his troops to ignore the cities along the way and flew south, Goryeo Hancheng was preparing for street fighting.

This time, Zhang San specially sent a division of troops to assist Goryeo in defending Seoul, and this time he was going to give the Jurchens the second largest one, using the entire Seoul as bait to destroy at least half of the Jurchen troops.

The two sides were in full swing to prepare, when the Jurchens arrived at the city of Seoul, the Goryeo soldiers defending at the head of the city were still a little nervous, and according to the requirements of the battle command, only 10,000 defenders were placed on the wall of Goryeo, making a look of insufficient troops.

Wanyan Aguta saw the sparse Goryeo defenders on the city wall, and laughed with satisfaction, sure enough, as he guessed, the next thing is to attack the city, Seoul has a moat, so the Jurchens have to fill the moat before the siege.

Wanyan Aguta directly ordered the cavalry to take soil and ride horses to fill the river, and as a result, the 10,000 soldiers in the city were musketeers, this method of filling the river was equivalent to exposing the cavalry to the enemy's muskets, and Aguta was also ruthless, if the cavalry died, he ordered to throw it directly into the moat, regardless of casualties and struggled to fill the river.

He planned to take Seoul before the Goryeo border soldiers returned, otherwise he would be in danger of being besieged, and spent a day filling in several roads leading to the city wall, and the Jurchen cavalry began to carry explosives bags and threw them under the city wall.

As a result, the commander sent by Qi this time was Zhu Wu, and Zhu Wu laughed when he saw that the other party was doing this, these two bullshit don't understand and dare to use explosives, so the Jurchens haven't piled up a few packs, and a rocket on the city wall shot down and directly ignited the explosives.

As a result, the Jurchens tried several times and all of them were this result, and only then did they know that there was still this reason for using the car, so the Jurchens went to look for the car again, and the car was just about to rush forward, and Ah Guda thought that it was not right, if the enemy fired a rocket directly, the whole car would soon be blown up?

After Yan Agu beat and found a cowhide to cover the explosives, there should be no problem in this way, right? As a result, they forgot about a weapon that Qi used to use, that is, a ballista to fire oil bombs!
