Yicheng, as the lower capital of the Yan State, has always been a military town built to prevent the attack of the Central Plains and even the Rongdi located in the hinterland of China.

As one of the few important military towns in the Yan country, it is bounded between the North Yi Water and the Middle Yi Shui. The west is adjacent to the Taihang Mountain, the south is adjacent to Yishui, and the east is connected to the Hebei Plain, the terrain is dangerous, condescending, easy to defend and difficult to attack!

Therefore, even if the Qi coalition army now has a total of 300,000 troops to fight Yan, with this majestic city, Zizhi will dare to fight with the coalition army!

In today's world, the defense of the city is not as imagined by later generations, just defending on the city wall. If a city cannot freely obtain supplies from outside the city and have people enter and exit freely, then no matter how strong the city is, it is just a dead city!

That is to say, the defense of any city must be based on the ability to defeat the opponent in the field! If you can't do this, no matter how strong a city is, it's just a fortress of death! This is like the Great Wall of later generations, what is really used for defense, in the final analysis, still relies on the army that can move freely outside the city, relying on people, not the city wall like dead things!

Zizhi naturally understood this truth, so as soon as he came to Yidu, he was ready to fight in the field with the coalition forces!

Because of the efficient work of the Taoqiu merchants, the transportation of the logistics of the coalition army was even faster than that of the Yan country's own operations! Therefore, when Zi Zhifang came to Yidu, he did not immediately engage the coalition forces, but continued to hoard supplies!

Facing Yidu, whose city gates were closed, Kuang Zhang did not have a good way for the time being. At this time, Xiao Xiang began to propose to Kuang Zhang that as long as he waited for a period of time and waited for the siege weapons of the Song army to arrive here, then it would be easy for the coalition army to break through the city of Yidu!

Kuang Zhang, as a famous general of Qi State, deeply knows the characteristics of mercenary-style soldiers like Qi National Skilled Fighters, and it is okay to let them fight a good fight, and really let them risk their lives to climb the city wall, if they don't pay a very high reward, no one is willing to do such a thing at all!

As a famous general of Qi State, he is very familiar with the war trends of all countries in the world. He had long heard that the Song Kingdom had developed a ballista that could fire stones, and a super powerful crossbow machine that could attack the defenders on the city wall on the ground, these were all heavy weapons for siege! With these heavy weapons, not only can he reduce casualties, but also allow him to win quickly! In this way, just waiting under Yidu City for a while, it is nothing.

And the Song army's request for the Qi coalition army to wait under the city of Yidu is not a simple process, but a deliberately created result! If it is based on the current march of the Song army, it is not very difficult to bring weapons such as bed crossbows and ballistas, but why did the Song army deliberately add such a procedure?

In fact, everything is for profit! Now in this battle of Yan, the victory or defeat of the coalition forces actually has little impact on the Song State itself. And the only benefit that the Song State could gain from this war was nothing more than that the Taoqiu merchants could profit from it!

Let the army of as many as 300,000 people, every day under the city of Yidu, how much food will be consumed! And all this grain must be supplied by Taoqiu merchants! Therefore, the longer the coalition army stays under the city of Yidu, the more abundant the benefits of the Taoqiu merchants from the battle of Cutting Yan!

When the coalition army was under the city of Yidu, after waiting for nearly twenty days one after another, the Song State finally transported the equipment needed for the siege to the city of Yidu, and at this time, the materials that Zizhi had hoarded were also ready!

After having sufficient material reserves, Zizhi transferred almost all the troops in his hands that could be collected from Yan Kingdom to the city of Yidu, with a total of nearly 150,000 troops, to guard Yidu together!

When the army was in place, he took the lead and launched an attack on the coalition army!

In the land of Yan Zhao, there are many generous and sad people! Because Yan is located in the north, the environment is difficult and dangerous, and its people are mostly mixed with Rong Di, so Yan people generally like to be brave and ruthless! They are different from the situation in Qi country, advocating martial arts and fighting privately, the Yan people are not fighting privately, but fighting, their fights are not playing, they are all desperate if they don't agree with each other!

The one who can best reflect the character of Yan Ren is Zhang Fei at the end of the Han Dynasty. This guy is proud of himself as a Yan person, and whenever he comes into contact with the enemy, he will yell "I am Yan Zhang Yide"! This perception is just like the guy who sold cakes in later generations, encountered the inspection of the city management, and yelled "I am XX people"! That is a general manifestation of a region, a strong regional character formed for outsiders!

Yanren is such a group with a strong and martial spirit! Now those who are willing to follow Zizhi here are mostly Zizhi's descendants, and in their opinion, the coalition organized by the Qi State now, nominally crusading against their prince, is actually an invasion of the Yan State!

Under the infection of this simple patriotism of defending his hometown, the morale of the Yan army is extremely high!

Looking at the army of Yan that rushed over with the determination to die, Kuang Zhang was not moved at all! In order to fight against these armies, he did not send the Qi army, which was mainly a skilled fighter, to fight, but let the armies of Zhongshan and Song resist the attack of the Yan army!

As a country established by Rong Di, Zhongshan is also a country with a strong martial atmosphere! This time, in order to move them, Qi State took the initiative to promise that he could cede the land of Yan State to Zhongshan State! Therefore, this time, Zhongshan attaches great importance to the matter of cutting down Yan, and with the strength of the whole country, Sima Xi personally led an army of 80,000 to cut down Yan!

Since the Zhongshan Kingdom moved to the north and bordered the Yan Kingdom, the two countries have been at war many times. Therefore, Zhongshan Guo is very familiar with the character of the Yan people and even the combat methods of the Yan army! As soon as he saw the Yan army rushing up directly, Sima Xi immediately ordered the Zhongshan army to attack, and the Yan army was in a scuffle!

There are no fancy moves in the fights between the two sides, all of them are lethal fights! And the combat methods of the two armies are also very similar to a certain extent, they are both consumed with human lives, forming a giant meat grinder on the battlefield!

On the other hand, the Song army's combat methods are completely different from the Yan army and the Zhongshan army! In the impression of people in the world, the Song people are stupid, stupid, honest and other images. The Yan people obviously knew something about this, and as soon as they launched an attack on the Song army's large array, they looked extremely "excited"! Some people yelled, some put hideous masks on their faces, and some people took off their shirts directly, and they came up with various ways to scare the more "stupid and stupid" Song army!

In the face of the attack of the Yan army, Xiao Xiang, the commander of the Song army, remained immovable. Ordinary Song people, because they pay more attention to faith and righteousness, do give people a stupid feeling, but since he started training the army, he has to admit that the honest character of the Song people is more suitable for training a strong army!

In the face of the Yan army's frenzied attack, the Song army's large array was quiet and motionless! When the Yan army approached, the entire army, under the command of Xiao Xiang, began to respond in an orderly manner!

The sword and shield men at the forefront began to meet the battle, the spearmen behind them began to cover, and the last crossbowmen, and even the bed crossbowmen, began to concentrate their long-range firepower and attack!

The entire Song Army Great Array, under the command of Xiao Xiang, is like a smoothly running machine! Unlike the machines in the Song Kingdom that were able to make all kinds of items, this machine composed of armies did not make anything, it would only output "death" with maximum power!

The weapons and equipment of the Yan people are extremely backward compared to the Song army! Among their weapons, only a very small part of them are iron, most of them are bronze, and the remaining part of the weapons even have stone tools! And even worse than the weapons and equipment is the armor rate of the Yan soldiers, which is an astonishingly low number!

With most of the soldiers unarmoured, and they had no idea how strong the Song crossbowmen were, they immediately paid a terrible price!

The first wave of Yan troops who rushed towards the Song army's large array rushed over with full of blood, but before they reached the front of the Song army's formation, most of them were directly shot and killed before they really came into contact with the Song army!

It wasn't until the third wave of the army that the Yan army really rushed to the front of the Song army, and at this time, they were also extremely unhappy, because they were about to start facing the large array composed of the Song army's sword and shield soldiers!

To be fair, the Yan people living in the north, because of the harsh living environment, are stronger than the Song people in terms of personal courage and fighting skills! However, when they fought face-to-face, they were no match for the Song people at all!

Xiao Xiang was still shocked by the terrifying spirit of the Yan people at first, but when he saw the scene of the battle between the Yan army and the Song army, he was not worried at all!

When the Yan army and the Song army were fighting, everyone came to the Song army with a decisive momentum, which was indeed very in line with the character of the Yan people! However, the Song army that fought against them was not a single person, but a whole!

When the soldiers of the Yan Army rushed over with short swords, when he caught an opponent and started to attack, he would find that the soldiers who were dealing with him were not one person, but a group of people! Every time he swung a sword, Song Jun's sword and shield hand had at least three swords stabbed at him!

Even if they were braver and more skilled than the soldiers of the Song Army, one sword could not fight three swords at the same time! And what is especially crucial is that the weapons in the hands of the soldiers of the Song Army are sharper than the weapons in their hands!
