The battle of Changning City lasted for a month.

This month also became a turning point of the northern expedition. Later, Murong yuan and Su Yunchu traveled all the way to the northeast. In this winter, that is, at the end of the year, they finally won three land lost cities. In only half a year, the Northern Expedition army led by Murong yuan was overwhelming, leaving Beiliang powerless to parry, and the good news of the Northern Expedition continued to spread to the capital, It was introduced into the ears of Yongye emperor, which made Yongye emperor happy and worried.

However, Beiliang Zhongzhong made some remarks. From the beginning, he was afraid of Murong yuan, the cold faced God of war, and finally called Murong yuan and Su Yunchu the "devil couple".

In half a year, three lost cities, with the speed of myth, soldiers in Beiliang spread rumors one after another. Don't say that King Jing used his troops like God, but Princess Jing was fascinated by them. Especially in the past few months, the Northern Expedition army was like breaking bamboo, and Su Yunchu played an important role in it, especially the blue eagle crossbow and arrow team under her leadership, It directly turns the marksman of Beiliang into an invisible person.

However, Princess Jing's use of troops is weird and there is no certain rules. In the words of Beiliang soldiers, Princess Jing's use of troops is like a demon, which can arouse everything in heaven and earth and act as her own troops. However, in Su Yunchu's mouth, the simplest explanation is that she likes field warfare and acts as her own soldiers with mountains, rivers, plants and stones, so, Beiliang suffered from fire attack and water attack.

Indeed, others may not understand, but Murong yuan, who has always been with Su Yunchu, knows. Su Yunchu's use of troops is very different from him. Su Yunchu does not take attacking the city as the main goal, but only aims to annihilate the main forces of the enemy. Finally, all the results that do not become her goals have become the results of annihilating the main forces of the enemy.

Su Yun initially reviewed the situation and emphasized the pursuit war under specific circumstances. More importantly, Su Yunchu also paid attention to the fortification project, making the artificial fortification area he built into an ambush to lure the enemy into depth and then annihilate it.

Su Yunchu was good at field warfare and Murong yuan was good at the Great Wall war. They complemented each other. As the war progressed step by step, the name of the devil couple spread among the soldiers of Beiliang.

However, Su Yunchu understood that only accurate pre war budgets, military and political understanding of the enemy and our two countries, and understanding of the situation of the two countries, can we better grasp the opportunity of combat.

It was not that she was preoccupied with troops, but that she introduced more systematic combat theories into a world where they did not yet exist.

During his military career, there was no grand concept of Chinese new year, but today is the new year's eve of Daxin. Kaisheng, which had just been attacked, was the lost land of that year. Now, the Northern Expedition troops are stationed in Kaisheng, and the two sides have entered a period of stalemate. Only by constantly exploring ordinary small battles, no one has let the other back.

Although Kaisheng has been ruled by Beiliang for decades, the custom of the new year among the people is still the same, but it is not so grand compared with Daxin.

At this time, both sides had no intention to attack each other violently. Even on the day of Daxin's new year, Beiliang and Daxin held one side and were deadlocked in the same place.

Even so, during the Chinese new year, the protection of Kaisheng is still very close. People can have a happy family and return to Daxin land. After the long lost Spring Festival, people's nostalgia for their hometown has always been deep-rooted. This deep-rooted comes from the recognition and inheritance of their ancestors' blood. Murong yuan has made them new people again, In the days before the northern expedition, people from generation to generation were looking forward to the way back.
