Bai Yijie had previously mentioned the value of these outer fortresses to Zheng Yunming. In fact, it was not just Bai Yijie, but almost all the generals and main staff had raised the issue of the outer fortress of Xiangyang with Zheng Yunming. Even literati and poets like Liu Kezhuang used his own "Traveling Baizhang Mountain" to talk to Zheng Yunming about how the Nanshan Fortress Group is important and that it needs to strengthen its garrison.

How could Zheng Yunming himself not know the importance of the outer fortress. Fortress offense and defense, the outer fortress have always been an inseparable part of the city offense and defense system. Zheng Yunming should have a deeper understanding of this aspect than this era. If the importance of the city and the outer castle in this era was five to five, then in the Christ's calendar, the importance of the outer and the city became 70% important and the city accounted for 30%. After that, the importance of the city in the city defense battle gradually weakened, and the periphery became the core factor of the city's defense. This is because the firepower delivery ability, the mobility and intelligence search ability of the troops in the era when Zheng Yunming lived in the past are different from the current war, so the space for war must be expanded infinitely.

In this era, various complex affairs in Xiangyang City tangled Zheng Yunming's hands and feet, making him unable to spare his energy to arrange the defenses of the periphery. As a result, Zhao Kui personally ordered the Jinge Deputy Chief Commander of Jinge to write a letter from Xu Yuanjie to uniformly manage the renovation of the outer castle. Xu Yuanjie is a young talented deputy chief Commander of Jinge, who is older and mature and steadfast. Although he is not as decisive as Zheng Yunming and others, he is very efficient. However, he is safe and does not keep his hands. Since he managed the renovation of the outer castle, he first rated the defenders of each castle to make up for the vacancies, and the officers in the city were selected to fill in some castles. Some of the lack of the castle were selected.

The commander of the throne began to renovate the city walls, add deer antlers, dig trenches, repair weapons, and dig wells. Finally, he replenished food and grass for each fortress. Wang Deng also sent people to supervise them to train the local terrain. Many of the outer fortresses were vacant before, or were defended by local militias and local soldiers at will. Once Jin or Mongolian soldiers approached, they would abandon the fortresses and flee in a hurry. However, an exercise conducted by the Deputy Chief Commander of Jing and E in August showed that after reorganization, these castles had become trustworthy strongholds in Xiangyang. If the Mongols did not spend some effort, it would be difficult to conquer them easily.

But Zheng Yunming also knew the suffering of the outer fortress hanging outside. The soldiers of this city were protected by the tall city walls of Xiangyang. They were large in number, sufficient food and grass, and had complete equipment to guard the city, so they naturally had high morale. However, the walls of these outer fortresses were short and the guards were scarce, and they were scarce. They were also the first to bear the attack of the Mongol army, so the morale of the defenders was difficult to maintain.

In order for these fortresses to exert sufficient combat effectiveness, they must be equipped with qualified defenders and tough defenders. However, the final outcome of these branch fortresses is that they are captured by the Mongolian army, and the soldiers either died in battle or surrendered. It is a pity that the loss of elite soldiers and good generals on the periphery is unreasonable.

How to control the scheduling? How to grasp it is a test of the general's overall planning ability.

Everyone talked about it. Time passed like the waves of the Han River. In a blink of an eye, the night was dense and the moonlight gradually became thinner. It was already past the third day.

At this time, a few blurry explosions came from the north of the city, and then, several dazzling sparks suddenly burst out from the Mongolian military camp leaning against the river bank in the north. Zheng Yunming recognized that it was the fire of thousands of enemies carried by the night attack team. Almost at the same time, fires also ignited in the Mongolian military camp outside the east gate.

The sound of shouting, explosions and rioting came from the north and east. The bonfires that were originally burning quietly in the Mongolian army became uneasy at this time. In the firelight, people could be seen shuttled back and forth, accompanied by the sound of weapons intersecting, loud shouting and scolding and war horses neighing.

Zheng Yunming held the pheasant with his hand and looked into the distance. The fires were spotted in the distance, and the sound of killing sounds were noisy. Literati such as Wu Qian and Ma Guangzu were just watching the excitement and did not understand the inside story at all. Zheng Yunming could clearly recognize that the flash of sparks suddenly was the quick gun being fired, and the sudden burst of fire was the bowl gun showing its power, and the intermittent series of fires at that time were the Song army using fire spitting barrels to burn the enemy's baggage and tents.

When Yang Xiao governed the army, he paid more attention to firearms than Wang Deng. Wang Jingsong said that whether he was arrogant or the spirit of warriors, in order to motivate the morale of soldiers in bloody battles, he always avoided the ejection of firearms from a long distance and encouraged him to narrow the distance between the enemy and us. Whether it was using spears and halberds to block the enemy's cavalry, or using knives and axes to fight with the enemy, he mainly encouraged the soldiers' blood, courage and courage.

Yang Fei was completely different. He once said to Zheng Yunming: "Beijing people are good at horsepower, so we must be good at firearms. When did you see the Mongolians fighting with us in close combat? Since they can use the advantages of war horses to the limit, wouldn't we be fools if we don't apply the advantages of firearms to the fullest? From then on, firearms should be placed in a position as important as the Northern Cavalry."

So with the support of Zheng Yunming's work, the Tulong Army was equipped with a variety of firearms, which could use suitable firearms to fight in the distance or in close combat. However, with the current firearm level, most of the time, it was just scaring the enemy.

However, Zheng Yunming knew that the most important thing about the night attack was to try to create panic and chaos from the enemy. It was not enough to just create the troops leaving the city. He shouted loudly: "Let the four-door bronze generals and the bamboo generals open fire to a halt the Tartars."

A series of huge fire and roar sounded on the four walls. Regarding the horrifying scene of this scene, Liu Kezhuang left a poem "Thunder from the sky and heard a hundred miles away". Although this was exaggerated, it was obvious that the Mongolian army in the distance was not indifferent to it, and the lights in the west were also rioting. Not only that, Zheng Yunming could even see that the Mongolian army camp on the north bank of the Han River also began an abnormal commotion. Could it be that Qin Wu from Fancheng was also taking action?

In any case, the setbacks suffered during the day were finally compensated in the darkness of the night. The commander of the husband was also excited and stood on the top of the city and said to Zheng Yunming: "With military horses like this, why worry about the unstable situation in Jinghu Lake?"

"Don't over-the-top praise." Zheng Yunmingxun thanked: "Only with the right soldiers to deal with the dignified formation can the surprise of the surprises. Otherwise, famous generals of all ages would not have to study the formation, but just organize various sneak attacks."

But he looked at the Mongolian camp in the distance, which was still turbulent, and felt a little comforted: finally Yang Xuan won a game for the Song army.

Yang Yu's troops returned to the city at dawn. With three loud quarrels, the soldiers guarding the city raised the iron gate of the water gate as promised, and one flatbed ship after another filled with captives drove in from outside the water gate. When they set out on the war, each flatbed ship was carrying ten soldiers, which were light and difficult to control. When they returned, they were loaded with weapons and supplies, and the river water was almost flooded with the boat boards.

"The rest is burned, try not to leave it for the Mongols." Yang Xuan picked the necklace while handing Zheng Yunming the gold medal engraved with dragon patterns. "I touched it in the tent of the enemy general in the chaos, and see what it was written on it?"

Zheng Yunming received the gold medal. A personal soldier raised the light and looked carefully, but there was no Chinese character on it, all of which were winding earthworm characters.

"Mongolian language imitating the Uighur character." Zheng Yunming shouted: "Let me translate it."

After the war ended last year, the city set up a recruitment hall and recruited various talented people, including translation talents who were familiar with Mongolian languages. In addition, there were many Mongolian prisoners of war in previous wars, including Mongolian knowledge. After being captured by the Song army, they naturally turned to the south to serve.

The guards of the yamen immediately brought a translator, who read the words on the gold medal to Zheng Yunming. It turned out to be a decree issued by Ogedei to the generals of the Southern Expedition, ordering scholars, Taoists, monks, diviners, doctors, and all the craftsmen from the south to pardon when they conquered the city and massacred the city, and sent them to the north to serve the Mongolians.

"What's the point of special issuance of decrees?" Yang Xuan asked in confusion: "After capturing the city, leaving beautiful women and craftsmen as slaves to drive them. Isn't it a prescribed policy for the Hu people to kill all the others?"

"The beauty of this command is not the craftsmen." Bai Yijie shook his fan and said, "They even need Confucian scholars, monks, Taoists and divination, and the knowledge in the middle will be deep."

Zheng Yunming said: "Mongolia originated from Shuofang. It was originally crude and unwritten. Now it has entered the Occupy Central Plains. It is natural to collect all the talents that are useful to them. Why should the military advisor be surprised?"

"What I am worried about is that the Mongols are adapting to how to be emperors of the Central Plains, not just the Khan in the north of the Mo River." Bai Yijie shook his feather fan and said to the tone, as if he was talking with his classmates in a thatched hut, rather than talking about the major events of the rise and fall of the country with the Lord: "You said these characters can be used to serve the Khan, but more of them can be used to manage the people in the north. Confucian scholars prepare officials, Buddhists and Taoism are believers, and divination stars are divining to calm the hearts of the people. If they gradually gain a foothold in Jiangbei with the help of the Fan and Han officials in the north and become a normal country like Jin and Liao, this is the most worrying thing."
