The team of the Fifth Brigade of the Imperial Front Protector Army was the captured Han army, and it was mixed with the Hakka people in Jiangnan. After the Tang Dynasty, the Han people in the north basically lived under the rule of foreign races, went through Liao, Jin, and returned to the Yuan, lived in war for a long time, and lived together with nomads, forming a martial spirit and developing a brave and ruthless character. In the context of regime change, they have also lost their sense of national identity and the concept of the state, and have become a special group that only submits to the strong, depends on the strong, and is free from the orthodox Han Chinese.

But in the eyes of the aliens, the Han people in the north are still Han Chinese, not of the same race as themselves, but only a tool for them to drive and contribute taxes. Therefore, most of them are still at the bottom of society, and they are the targets of oppression and exploitation by foreign races and used as cannon fodder, resulting in their hard and difficult lives, but they can only go with the flow under the oppression of the powerful, and it is difficult to change the fate of being driven.

The Hakka people were Han Chinese who migrated south during the Northern War, and their large scale and large population brought advanced technology and culture to the southern region, but they always had the heart to recover their homeland and hope to return to their homeland one day. However, the southerners regarded them as aliens, 'robbers' who encroached on their own land and seized their own production resources, coupled with the differences in customs and living habits, which led to constant conflicts between the south and the north, forcing the Han people who moved south to try to protect themselves, forming a unique Hakka group that was brave and ruthless, united against the enemy, and maintained their own customs and living habits, although it was still difficult to completely integrate after a hundred years.

Although these two groups of people are historically from the Han nationality in the north, they have long been divided into different ethnic groups, and there seems to be nothing in common except for being brave and warlike, but Zhao Yu just kneaded them together. But such a group that everyone is not optimistic about, after joining the Imperial Protector Army, the reality is surprising, they not only quickly adapted to the new life, but also felt very happy, and the two sides were 'playing' together.

Of course, this stems from the fact that Zhao Yu was a grass platform team when he formed the Shuaifu Army, and the source of the members was very complicated, but it was used regardless of background or qualifications. Everyone comes from all over the world, whether it is a slang person, or a Han person, a prominent family, or a small family, as long as they have the ability, they can be awarded and promoted, so the new Song Army has a good tolerance, and when these people take the position, they also do things according to this convention, don't say the second brother, your commander may have been a soldier in the past, and there is no question of who looks down on whom.

At the same time, the army also has its own specialities, there are not so many twists and turns here, especially the New Song Army, as long as you abide by military discipline and state law, obey orders, and no one interferes with your belief in Buddhism and Taoism, relatively speaking, it is still very relaxed. In addition, the Song army is well treated, with clear rewards and punishments, no one will cheat your life money, no one will embezzle your bounty, take your military merits, and will not let you do anything other than performing military duties, which is a hundred times stronger than the Mengyuan army.

Therefore, these soldiers quickly found a sense of belonging, and they felt that even if they worked hard, they had to find a good owner. In today's battle, they fought a little timidly at first, and acted in strict accordance with military regulations. But when the two armies entered hand-to-hand combat, they gradually found a feeling that they were originally born from dancing knives and guns, and playing with cold weapons was even more convenient than muskets. In addition, after the courage in the heart was stimulated by the tragedy, the battle became more courageous, although there were continuous casualties, but it did not affect the morale at all, not only held the head of the city, but also repeatedly counterattacked the enemy troops who went to the city.

When the fierce battle on the city was in full swing, Sima Huang Fan of the Fifth Brigade also led the army out of the city from the Zhenshan Gate, quickly defeated the Meng Yuan army besieging the city, captured the predetermined hill, and quickly expanded, using this as the center to build a defensive line to cover the artillery to establish a position. The Mongol army was stunned by this sudden Song army, and immediately launched a siege after coming to its senses, and the Weiyuan artillery of the Song army on the city immediately began to fire, blocking the passage of their attack and assisting the Song army out of the city to consolidate their positions.

At present, mortars are all supporting firepower, and each battalion is organized into a detachment, with three artillery squads and one ammunition squad, each equipped with two guns. The detachment sent this time was a mortar detachment of the third regiment, and the mortars they were equipped with were of large caliber and small in establishment, but they were of the scale of the capital level, with 18 guns. After arriving at the predetermined location, they did not hesitate to set up their positions, set up artillery, and measure the number of shots. After the preparations were completed, the artillery was immediately opened on the enemy troops attacking the western city.

The advantages of the mortar are that the gun body is light, the position layout is simple, the firing speed is fast, it can fight cattle across the mountains, and the target can be changed quickly. The artillery detachment was divided into two groups, one group was responsible for striking at the besieging enemy forces, and the other group was responsible for intercepting the following enemy troops. The three-inch diameter cannonball kills more than two zhang, and a salvo can cover an area of twenty zhang, and for a time the explosions under the city are continuous, and the enemy troops who have landed in the city are destroyed and killed, and they are scattered to hide, but there is no place for them under the dense artillery fire.

And the door panels and shields of the Meng Yuan reinforcements who arrived later couldn't even stop the bullets, how could they stop the cannonballs that were whizzing and falling from the sky, easily penetrated the door panels they were holding high trying to cover the bullets, and then exploded in the crowd. The people at the center of the explosion were so broken that they couldn't fight it even if they wanted to. Although the surrounding people were covered, offsetting part of the power of the explosion, the fragmented shrapnel flew everywhere, penetrating the armor and human body without hindrance, so the people on the side of the explosion were almost not spared.

'Whew......' Luo Datong looked at the enemy soldiers who retreated like a tide in the artillery fire, wiped the blood splashed on his face and breathed a long sigh of relief. The soldiers in the city also cheered, and they threw the corpses of the enemy soldiers in the city into the city, with a smile on their faces that they had survived the war.

'Woo woo ......' Suddenly the trumpets of the enemy camp sounded again, and everyone immediately moved in, and the soldiers quickly entered the battle positions under the supervision of the officers, but they found that there were no enemy troops in front of the city.

"Oh no, fooled!" Luo Datong looked to the north of the city through the smoke of gunpowder, and saw that a banner had been erected in the direction of the city wall of Yushan, and the mountains were full of Mengyuan enemy soldiers.

He immediately realized that the enemy's main attack direction was Yushan, and Ximen was a feint. Taking advantage of the fact that they were too busy defending themselves against the enemy attacking the West Gate to pay attention to other directions, they quietly sent troops to gather troops at Yushan Mountain, and took advantage of the mountain to conceal themselves to approach the city wall. When their own forces were attracted to the direction of Xicheng and firmly pinned down at this time, they suddenly launched a full-line attack on the Yushan city wall, although the mountain road was rugged and difficult to walk, but the city wall was low and conducive to climbing. In the face of an attack on the whole line regardless of casualties, the defenders inevitably lost one or the other. And the shelling just now only disrupted the rhythm of the enemy's offensive and forced them to launch in advance......

At this time, he felt that the situation was not good, and he was fooled by Zhenjin who was far away in Dadu, and he had already received the news that Yuxi Timur led an army of 100,000 troops to smuggle across the Yangtze River and attack Jiangnan. The court was jubilant, and he also felt full of confidence, thinking that as long as the army recaptured Jiangnan and defeated the puppet dynasty, then all the current problems could be solved.

But after Zhenjin calmed down after jubilation, he felt uneasy, he felt that it was too easy for an army of 100,000 to cross the Yangtze River so easily and attack the hinterland of the Southern Dynasty. It is true that his plan to allow Yuxi Timur to invade the south was also carefully considered, taking into account all kinds of difficulties encountered, and made corresponding countermeasures in a targeted manner, and even secretly summoned Yuxi Timur to Beijing to discuss the details before the implementation, and then made up his mind to invade the south.

Zhenjin knew that this battle plan was not perfect, and it was not in line with his attitude of seeking progress steadily, and even said that it was a risk, gambling with the fortunes of the country. But he also knew that he had no choice but to get through the crisis in front of him. Only through quick battles, quick attacks to seize the enemy's key points, and then divide and encircle, annihilating the enemy's main force can victory.

First of all, after the Song army recovered Jiangnan, the whole court realized that their own human and material resources were insufficient and could not survive a protracted war. You can only fight quickly and use quick raids to determine victory or defeat before the opponent's strong strength is fully realized. And this kind of precedent has repeatedly appeared in the process of the rise of the Mongols, relying on their rapid mobility to destroy Jin and Xia, and to attack the northwestern countries, and the generals of each army are very familiar with this method of warfare and have the ability to organize the southern invasion.

In addition, since Kublai Khan established the Great Yuan, an important problem that has always plagued them is that they are fighting on two fronts, and it is difficult for him to conduct two-front operations at the same time due to the limitations of national strength. The current situation is even more serious, the sea capital frequently disturbs the borders, and contacts the countries to invade them, and the Southern Dynasty seems to want to maintain the status quo, but Zhenjin understands that the little emperor has not given up the idea of entering the Central Plains, but is only accumulating strength. In the absence of the ability to start a war on both sides, he could only choose to attack and destroy the Southern Dynasty that posed the greatest threat to him first, and use the wealth and resources of Jiangnan to buy off the kings of the northwest and jointly fight to destroy Haidu.

In addition, Zhenjin also realized that the combat effectiveness of the Mengyuan army was gradually declining, and the veterans with rich combat experience either fell in the southern and northern wars, or they had a heart of pleasure and devoted their minds to collecting money. He thought that the longer the time dragged on, the more the veteran generals who had the ability to command the troops skillfully using rapid mobile tactics, commanding the troops to carry out encirclement and encirclement, annihilate the opponent's troops, rapidly develop in depth, and achieve victory, after the day was gradually withering, no one would be able to command the army to cross south and retake Jiangnan.

Based on this situation, Zhenjin, who was eager to break the situation, had no choice but to let Yuxi Timur organize a plan to invade the south, but when he successfully crossed the river now, he was worried about whether this was another trap deliberately laid by the little emperor of the Southern Dynasty to lead him to the ......
