When the Ministry of Works was asked to make horseshoes the next day, no one believed that four such thin pieces of iron could save a warhorse that had been retired due to worn hooves.

Chu Fan had a warhorse that was supposed to be eliminated brought in and personally shod it. Then, Chu Fan mounted the horse and galloped away under the astonished gazes of the crowd. The hooves made a crisp sound as they collided with the cobblestones, but the horse showed no signs of discomfort. Before the horseshoes were fixed, it would have limped or fallen due to wear and tear, but now it was behaving more steadily than a normal warhorse.

Chu Fan briefly explained the principle of horseshoes to everyone. They also knew that these four pieces of iron can effectively protect the hooves of war horses and reduce wear, thereby greatly extending the service life of the war horses and improving their stability and speed on various terrains.

Although Chu Anran and the others were shocked, they also knew that this invention was a timely relief for the Wei army. The Wei state would be able to significantly reduce the wear and tear of its warhorses. With the horseshoe, Wei's warhorses could gallop longer on the battlefield, and Wei could also recruit more cavalry. This would greatly enhance the mobility of the Wei army on the battlefield, and after defeating the Qian Kingdom, it would have a greater chance of winning the war against the Xiongnu.

Originally, Chu Anping and other court ministers were still worried that Wei did not have enough cavalry. If a war broke out with the Huns in the future, Wei's cavalry might be at a disadvantage. Even if they defeated the Huns through the advantage of weapons, they might have to pay a heavy price.

If Wei did not have enough cavalry, it would be difficult for the Wei army to wipe out all the Huns if they wanted to escape. With horseshoes, those war horses that were originally required to be retired could be put back into battle, and in this way, Wei's cavalry force would increase exponentially.

Because horseshoes are very simple to make and require only a few materials, Minister of Works Tang Hongwen and his craftsmen produced hundreds of thousands of horseshoes in just two days, enough to equip the country's war horses.

A large number of horseshoes were transported to Los Angeles by rail, and then transported to various front-line military camps by hot air balloons.

After receiving the horseshoes and learning how to use them, Mu Yunfeng immediately had them nailed to all the horses in the army. The horses that were about to be retired regained their vitality. Suddenly, the Wei cavalry more than doubled in size, and with so many cavalry, the Wei army's mobility was greatly improved.

A month later, the Wei army reached the capital of Gan State. The emperor and court ministers of Gan State originally planned to flee, but all the directions of escape were captured by the Wei army. Only the emperor of Gan State was left unconquered by the Wei army.

When they saw that they could no longer escape, the Emperor of Gan State and the court ministers decided to defend the city to the death. If other countries had attacked Gan State, they might have opened the city and surrendered long ago, but the Wei army's policy towards prisoners made them dare not surrender to the Wei army at all.

You must know that if other countries attacked Gan State, if the emperor and ministers of Gan State surrendered voluntarily, they could at least save their lives and some wealth and glory. At that time, the rulers they were attacking would also treat them well in order to consolidate their rule on the land of Gan State.

However, the army of Wei State was not like this. They would let the people judge themselves and use their own lives to win the hearts of the people of the country.

In the history of Shengwu Continent, as long as the emperor surrendered, he would most likely be treated well, because this was a tradition and convention as well as a tacit understanding between rulers. No one could guarantee that they could remain undefeated forever, and they needed such a retreat when they were defeated.

But the current Wei State has broken this tradition. As long as the emperor of a country is cruel and inhumane when in power, he will be sentenced to death when facing the trial of the people.

The emperor and court ministers of Gan State were also very aware of this, so they did not dare to surrender to Wei State at all, because once they surrendered, they would be beheaded or even their entire family would be destroyed.

Under such circumstances, the emperor and court ministers of the country could only decide to defend the city to the death. Perhaps only in this way could they have a glimmer of hope.

When the Wei army arrived at the capital of Gan State, they did not immediately launch an attack on it. Instead, they surrounded the capital of Gan State, preventing the people in the capital from escaping. At the same time, they cut off the connection between the capital of Gan State and the outside world, making it an isolated city.

After seeing this situation, the emperor of Gan State immediately ordered warriors to break through the Wei army's defense line and ask for help from other countries, hoping that other countries could send troops to rescue Gan State. However, few warriors could break through the Wei army's blockade. Even if there were warriors who successfully broke through the Wei army's defense line, other countries did not dare to send troops to rescue Gan State after seeing that the Wei army was so powerful, for fear of angering Wei State and attracting the Wei army to attack themselves.

With no one to turn to for help, the emperor of Gan State could only pin his hopes on whether Gan State's capital city could be defended. As long as Gan State's capital city could be defended until the Wei State's army ran out of food and grass and retreated, Gan State would still have a chance of survival.

The reason the emperor and his ministers of the State of Gan believed this was because, whenever Wei captured a city, it would distribute the city's grain to the local people to win their hearts. Wei's army of hundreds of thousands relied entirely on food and fodder transported from the Wei mainland to maintain its supplies. The capital of the State of Gan was far away from the Wei mainland, and the transportation costs were enormous. They didn't believe Wei could truly hold the imperial capital for long. Furthermore, they didn't believe Wei had enough food to support such a large army.
