Wanyan Yulie is considered a veteran of the Three Dynasties, and he has followed Taizu, Taizong and Wushu to fight for many years, and he also has a crippled leg. When Wushu conquered Goryeo, he suffered a great defeat, and his appearance was not good, so he was sent by the Taishi to Taizhou to serve as the commander of the army, responsible for guarding against the Mughuls. After the Song army occupied Linhuang Mansion and Dading, he was ordered to supervise the construction of boundary trenches. Seeing that his former colleagues were all officials in the court, and he had to drag a stump to repair the boundary trench, he couldn't help but feel desolate.

When the imperial court was planning to rebuild the left and right marshal's mansion, Wanyan Yulie thought that he was also a member of the royal family, and he was old, so he couldn't touch the marshal, so it was possible to at least get a prison guard. But the edict is that the marshal sent is a hairy child, he was not born when he was fighting, and the overseer army is that nerd, he is still in place or the capital army, but the power has been greatly reduced, there are two more 'emperors' on the top of the head, and the capital has also moved from Taizhou to the much smaller Lekang City.

Wanyan Yulie was originally angry about this, and then the right commander led the troops into the grassland to chase down the Tatars and transfer the elite from him, but did not take him to 'make a fortune'. And the hairless child with his mouth did not have him, the veteran commander really caused trouble, in order to kill the contempt of Wuzhen, he 'strayed' into the enemy territory and clashed with the Song army, which caused the Song army to mobilize heavy troops to retaliate, and disturbed the border area unpeaceful. But the hairy child thought that it was just a conflict caused by 'straying' into the enemy territory, and didn't realize that he had fallen into the trap of the Great Song Dynasty.

Wanyan Yulie can be said to be the most experienced general in the northwest region who fought the Song army the most, and he was not satisfied with the strategy of Wushu to manage the grassland, and the Jin State's intervention in grassland affairs was a failure. Although the Mughals dominated the steppe, they were able to force the Tatars to move closer to their side. It also made the Song Dynasty cocoon and unable to enter the grassland, and the growing power of the Mughal people would also become its heart disease. But Zhao Er will never let it continue to expand, and will definitely find a way to curb the unrestricted development of the Mughal Tribe. It's good for the country to sit and make profits.

In the end, it was the Dajin State that couldn't hold its breath first, and united with the Tatars to hit it hard, removing the heart disease for the Great Song Dynasty, and also breaking the balance of power on the grassland, making the Tatars grow like weeds after the rain, like a well-fed dog not watching the door, and then threatening the interests of the Jin State. Feeling threatened, Jin Guo made a mistake again at this time, instead of leading the disaster to the Great Song Dynasty, he once again used the simple way of extermination. The grassland has become a 'terraule' land, and a gap has been opened in the border line, which has greatly reduced the role of the boundary trench.

And since the year before last, Zhao Erbei had already realized that the Song army was going to take action, and all he lacked was an excuse, otherwise he would have started fighting a long time ago. The disappearance of the messenger, the loss of the edict, the alliance with the Tatars, and so on, as long as you think about it carefully, you will find that it is actually a conspiracy planned by the Great Song Dynasty.

At that time, after discovering that the messenger was missing, the spies of the Jin army searched the grasslands and did not find a single person, which can be said to be very strange. The Tatars bought the lost edict with a lot of money. The fire paint was intact, which meant that the people present at the time did not know the contents at all, but after the Tatars moved away from Yuerluo overnight, the Song Dynasty immediately sent an envoy to communicate with them. It shows that they have already learned the contents of the edict. And they contacted the Tatars just to show the Jin Kingdom, so that the servant Sanzhong thought that there was a big incident that burned his eyebrows, and the hairy child didn't want to think about it and stupidly pounced on it.

Then there is the border area of the Great Song Dynasty, which has always been heavily defended. Farms, forts, and even grazing along the border are their eyeliners. But that day, the group became blind and foolish, and the Jin army chased the Tatars for fifty miles until they cut off the head of the vulture. Da Song didn't know about it, wouldn't it be too weird. And when the Jin army retreated, the Song army happened to collide with them again, and after the conflict, the forbidden army suddenly escalated the conflict in a blink of an eye, indicating that it had already laid a trap waiting for them to drill into it! But when the Song army mobilized heavy troops to come after the reason of the Jin army's 'invasion', the hairy boy was afraid again, and repeatedly asked the court to transfer reinforcements, so that he could hurry to Ningbian Fort to block the Song army.

After Yan Yulie received the order, he sneered, the servant was too tender, the Song army knew that the boundary trench was easy to defend and difficult to attack, and he also transferred troops to attack, unless it was Zhao Er and the group of people he trained who let the donkey kick their heads, this is obviously their usual strategy of attacking the west, and their real target is Huining Mansion, as long as they appear there, the boundary trench defense line will collapse in an instant. Therefore, Wanyan Yulie wrote to the Taishi alone, asking him to be careful that the Song army marched east from the grassland to take the capital......

Wushu looked at the two completely different battle reports, and his heart was extremely entangled, he was sick and his legs and feet were not very good, otherwise he would definitely be happier than Zhao Erzhuan. The view of the Song army is that the Song army launched only a local war, and will not lead to a full-scale war; Wanyan Yulie believed that this was a war that the Song Dynasty had been planning for a long time, and their goal was not only the northwestern grasslands, but a full-scale war between the two countries.

Internally and emotionally, Wushu hopes that this is just an accidental border conflict, and that after a certain period of development, it will eventually be resolved through negotiations, and in the end, the two sides will divide the grassland and terminate the construction of boundary trenches and other hostile facilities, so that the conflict will end quickly; Judging from the current trend of the situation, Wushu believes in Wanyan Yulie's judgment even more, and it is likely that this is a full-scale war under the cover of border conflicts.

"Feint to attack Taizhou, attack Shangjing, and adopt the strategy of attacking the east and the west......"

"Could it be that Zhao Er used the skirmish on the northwest border to cover up his real intentions, and the south is his real main direction of attack, and this qiē will be an excuse for Zhao Er to provoke a war!" Striking the east and attacking the west is Zhao Er's usual method, and now the northwest border is full of war clouds, and the southern border is calm, which is really in line with common sense, and he was shocked when he thought of this.

The southern part of the Great Song Dynasty was convenient for transportation and canals, which made it easy to mobilize troops to transport supplies, and the forbidden troops stationed around Gyeonggi could reach the battlefield in a few days, and they could even mobilize Jiangnan troops to the front line by sea. In addition, from a strategic point of view, after losing control of Yanyun, the economic center of the Jin State moved northward, mainly distributed on both sides of the Liao River, where prefectures and counties are densely populated, and are important sources of taxes and grain.

Wushu understood that the current Jurchens were no longer able to rely on bows and horses to fight the world in the early days of the founding of the country, especially when fighting on their own territory, and could not supplement military resources by plundering, so the Great Song Dynasty could use its southern part as an offensive target to strangle the economic lifeline of the Jin State, and severely weaken their war potential, making it impossible for them to fight for a long time. The reason why there is no sign of war now is that Zhao Er is waiting for the arrival of spring in order to use his sailors to help in the war, and he will not let such a powerful military force be idle.

"What the hell does Zhao Er want to do?" The vultures were entangled to death, and swept the qiē on the long table to the ground. The current intelligence sources are complicated, contradictory, and controversial, and he can't determine the main direction of the Song Dynasty's attack, the northwest, south, and Goryeo can all become the direction of the Song army's attack, but this qiē is held in Zhao Er's palm, hidden in the fog, so that Wushu can't make a decision......

In the case that it is impossible to judge the direction of the war, the vultures can only be dealt with by means of comprehensive deployment and key defense. He deployed most of his forces in the Song-Jin border area, while at the same time stationed in Shangjing's Hoeryeong, Tokyo's Liaoyang, Jinhae's on the Liaodong Peninsula, and Jeongju, which was adjacent to Goryeo, as a mobile force ready to defend against the Song invasion. The disadvantage of fortification everywhere is the shortage of soldiers, forcing the Jin State to start a large-scale conscription of soldiers, and each Meng'an and Mouke stopped farming and reported to the Wanhu Prefecture to which they belonged, and accepted the point collection.

Of course, he could not get reinforcements from the imperial court for a while, but he not only had to defend the boundary trenches for hundreds of miles, but also divided his troops to defend the huge gap left by the destruction of the Tatars, and prevented the Song army from entering Beijing. At the same time, he ordered all the young and strong men along the border forts to enter the fort to defend the city, and used the method of drawing one from the people of all ethnic groups to recruit and sign troops to assist in the war, and won 50,000 soldiers. And these people all bring their own grain and grass, bow horses, and the state is not responsible for providing them, so they naturally cause a lot of complaints.

At this time, the Song army launched an all-out attack, and the goal was gradually clear, the sword of the Kryu army pointed to Taizhou, the Longyi Army attacked Wuzhou in the southern section, and the Lion Wing Army was responsible for Xingguo in the northern section. Wanyan Yulie understood that the Song army was using the tactics of breaking through in the middle and outflanking the two wings to seize the main road to Changchun Prefecture and defeat the right Marshal Mansion in one fell swoop. The three places attacked by the Song army were important support points for the boundary trench defense line, and if one was broken, the defense line was opened.

Wanyan Yulie could only divide his 50,000 troops into 20,000 teams to guard the two ends, personally led 20,000 troops to guard the middle section, and the rest of the men and horses would guard the various fortresses on the boundary trench with the fort soldiers. There were a lot of people looking at it, but he understood that the Song army in front of him alone had 60,000 people in the forbidden army, and there were no less than 100,000 archers from the state army and the Fan army who assisted in the battle. Judging from Wanyan Yulie's experience of fighting with the Song army many times, in the case of equal strength, the field battle is the end of being completely annihilated, and the defense of the city cannot hold out for ten days, so he began to ask for help from the servants of the Dutong army, and asked him to bring the army to come quickly!

As an outpost for the defense of Taizhou, Yongbian Fort became a hot spot for the two armies, and it was an important stronghold on the boundary trench defense line, and the breach of it opened the door to Taizhou. The Jin army guarding Ningbian Fort only had two thousand people and more than 1,000 people from the fort, looking at the banner covering the sun on the opposite side, and could not see the camp on the side, the guards knew that it was difficult to fight, and Wanyan Yulie knew that if this place was lost, Taizhou would lose the barrier, and hurriedly led the army to help.

At this time, it was already February, and the Kryu army besieging Ningbian Fort received the order to start the siege, and the prelude to the war was opened in the sound of 'rumbling' cannons, which also marked the beginning of the Northern Expedition of the Great Song Dynasty, and the result would eventually rewrite the history of the Great Song Dynasty......
