After receiving the report, Ni Liang decisively ordered the suspension of crossing the river and ordered the advance regiment of the cavalry brigade to send alerts to the enemy direction to find out the enemy situation. The army lined up on the east bank of Baishui, sent scouts to the north and searched north with cavalry on the other side to prevent the enemy from setting up ambush on the river, and would take advantage of the opportunity of crossing the river to launch a sneak attack. After a command, the units acted quickly, reconnaissance cavalry and the river basin prepared for battle with chariots. The stewards were placed in the formation, and the guard regiment and the baggage regiment formed two lines of defense.

Zhao Bing had already got off the car at this time. He was a little strange. According to the war report from Jingxiang, the Song army had completed the cleaning of the periphery of Xiangyang and trapped the enemy in the city. Xiangyang was surrounded by water on three sides and one side surrounded by mountains. There were mainly two land passages, which went west through Wanshan to Shiyan and Hanzhong; south through Xianshan and to Jingzhou. The Suzao Road they were walking through the edge of Fancheng on the north bank of Xiangyang. In theory, the enemy would not appear here.

"Your Majesty, I thought the enemy troops discovered should have been sent by Fancheng!" At this time, someone had already set up a shed under the car, which could not only shade the sun but also prevent the waves from falling. Someone put on the table. Xu Wunan spread the map on the table and pointed out.

"Why are you so sure?" Zhao Bing asked without raising his head.

"Your Majesty, Xiangyang is located at the intersection of Tang River and Baihe River, and then the convergence flows into the Han River. Xiangyang is located above the intersection of Sanjiang River. Xiangyang City is backed by Xianshan, Hutou Mountain, and many other small mountains. Under this terrain, Xiangyang becomes an easy-to-defense and difficult-to-attack place, making it a name as solid as a golden soup. The surrounding mountains divide the open space outside Xiangyang City into two relatively small, closed and isolated spaces, but it also makes the roads entering and leaving Xiangyang by land, with only two roads in the west and south entering the city. Our army came from the south and should have closed these two land passages long ago, so it will be determined that the enemy was from Fancheng." Xu Wunan explained.

"It's too long-winded, I can understand the map!" Zhao Bing frowned and said in a deep voice. He already agreed with this in his heart, and was satisfied with it after several days of observation.

Xu Wudan was ordered to form a military affairs office and came up with a plan the next day, which was to integrate the military affairs and personnel of each office of the Imperial Front Office first, and then use this as the basic staff to separate the corresponding affairs. Insufficient personnel will be transferred from the Imperial Front Guard Office nearby. In this way, it is possible to quickly set up the shelves, and still use old people familiar with the business will not stop the work.

If you directly draw relevant personnel from the Imperial Front Guard Office, you can skip the cumbersome review, because the Guard is His Majesty's personal army, and all the personnel are selected through layers of selection before they can enter. They all have practical experience, which can make up for the shortcomings of the original Imperial Front Office staff. In Zhao Bing's view, this plan is suspected of being a trick, but it is the most pragmatic approach, so that the team can be set up in the shortest time.

Of course, this may not be as capable as a choice, but the military affairs office established is enough to deal with the current situation. It can be seen that Xu Wunan is a talented person to respond. In the face of the emergencies that just happened, the military affairs office can respond as soon as possible, make analysis based on a small amount of intelligence, and put forward its own opinions, indicating that it has initially had the ability to "actual combat".

"Your Majesty listens to the report and does not like complexity and length. You just need to explain the situation briefly!" Chen Shishi reminded him. At that time, Duke Zhuang resigned from his post and was in charge of the imperial court. He was responsible for giving advice and teaching to the new subordinates.

"Yes, I will remember it!" Xu Wunan politely said to the emperor and Chen Shishi one after another. But he felt a little fluttering in his heart. This was the first time he made a suggestion, and His Majesty looked uneasy, which made him nervous.

"But the report of the Jingxiang War has already occupied Fancheng. Do you think the enemy is from Fancheng? Wouldn't it be the same?" Zhao Bing asked back.

"Your Majesty, I thought it was the fall of Fancheng, and Jinghu had no time to report it. Maybe our army voluntarily withdrew from Fancheng and reoccupied it for the enemy." Xu Wunan replied.

"Your guess is bold, but what situation do you think is more likely?" Zhao Bing sat down and asked with a smile.

"Well... I thought the possibility of voluntarily withdrawing!" Xu Wunan naturally knew that if he lost his important place for no reason and concealed it, it would be a serious crime in the army. He thought about it and reported it truthfully.

"How can I see it?" Zhao Bing asked again.

"The last general has read the Fancheng Zhi, which records that Fancheng has frequent floods, with water depths of several meters, and often flooded the city. Moreover, there has been a saying in Xiangyang: Xiangyang is made of iron, Fancheng is made of paper. It means that Xiangyang is made of iron, and Fancheng is made of paper because of its geographical terrain. Even if the iron is blown away by the wind, it will remain the same for many years. Fancheng is as fragile as paper. Once the flood comes, it will be beyond recognition and the entire city may be covered by heavy water." Xu Wunan replied, "It is the time when rain is frequent, which is very easy to cause floods. I think the commander of our army is worried about being attacked by the enemy, so he voluntarily withdraws from Fancheng, so as not to repeat the mistakes of Guansheng Water flooding the seven armies during the Three Kingdoms!"

"Your Majesty, what Master Xu said," Chen Shishi continued, "Fancheng is located on the north bank of the Han River, standing with Xiangyang River. After passing through the two cities for about ten miles, the Han River turned around and went south. On the boundary of Fancheng, there are also several rivers of all sizes. These rivers gather in the north to south flow, and eventually formed into two main rivers, respectively, at the turn of the Han River to go south, and each of them is poured into the Han River several miles apart."

"In the west and north of Fancheng, there are lands that range from dozens of miles across the land. These hills can reach dozens of miles high, and the lower ones can also reach several meters. The elderly stretch for dozens of miles, and the shortest ones can also reach several miles long. The distance between the two hills is dozens of meters to several miles, which makes Fancheng face water and the two sides rely on the road. In addition, compared with Xiangyang on the opposite side of the Han River, the terrain of Fancheng is relatively low and flat."

"So whenever the water news comes, the Han River rushes under the river, and the two rivers outside the city are heading upwards, which often cause the river to be unable to discharge under the water, and then it will form a flood in the Fancheng area. The overflowing river water circulates the city walls, and the city walls built with rammed earth are not afraid of drought, but are extremely afraid of floods, especially for long-term soaking and erosion of floods. Although the walls of Fancheng are built very tall, whenever the river overflows, they often collapse under the long-term soaking of floods and strong erosion of swirls, which will affect the military and civilians in the city."

"The Master Chen explained. Guan Sheng was stationed in Jingxiang for a long time, and he must be familiar with the local geography and meteorology. When the battle against Fancheng was raining in Dalian for more than ten consecutive days, the Han River surged and overflowed, and along the low-lying area of ​​the old Han River riverbed, the Han River was rushing to the Yikou River in three directions. Yujiagang went to Tuanshanpu area. In addition, the mountain torrents of Qinshui, Baishui, Chunshui and Putuogou, Huanglonggou, Heilonggou and other places in the northwest, causing the horizontal land of Yikou River, Yujiagang, Tuanshanpu and other areas to be five or six meters deep, causing the seven armies such as Yu Jin who were stationed in Fancheng to be flooded by floods and the entire army was wiped out." Xu Wunan added.

"Are you exonerating them? Once Fancheng loses, the cave in the north of Xiangyang will be opened. The enemy in the city will receive reinforcements from now on, which will inevitably cause great difficulties and uncertainty to our army's attack and lose great opportunities." Zhao Bing looked at the two and said solemnly.

"I don't dare to do it, it's just that!" the two of them quickly saluted.

"But the last general thought that Jiang Shuai would not misunderstand the consequences of withdrawing from Fancheng, and would take measures to prevent the enemy from reinforcements." Xu Wunan said again.

"Oh, what are the remedies?" Zhao Bing asked curiously.

"Your Majesty, the enemy who reinforces Xiangyang is nothing more than Nanyang and Junzhou. As long as our army occupy Dengcheng and Gucheng, we can cut off the enemy's reinforcement route. Especially Gucheng, this place is located in the western part of Xiangyang, the west bank of the middle reaches of the Han River, and the southeastern foot of the Wudang Mountains. It is adjacent to Jingshan in the south, Wudang River in the west, and the Han River in the east, and the two rivers in the north and south flow into the Han River, and then control the Han River in the thousand-year-old ferry. Moreover, rice is abundant here, and it has always been a place for Jingxiang military rations. As long as it is occupied, water and land transportation can be controlled and the road to aid Xiang Xiang." Xu Wunan pointed to the two places on the map and said.

"Well, I hope so, but once Fancheng is lost, our road to Xiangyang has been cut off, so we can only fight!" Zhao Bing snorted, and said without saying anything.

"I probably can only fight. The surrounding roads are difficult to pass. If you walk on the main road, you have to retreat to Suizhou, and then go by hundreds of miles, and enter Xiangyang through Yingzhou." Xu Wu nodded with a wry smile. He obviously had no good plans for a while. He turned to another sentence, "I thought the enemy was determined to know the suffering of Fancheng floods and would not garrison heavy troops to prevent our army from flooding the city. Our large group of troops passed by, so they might not dare to go out to fight."

"Haha, you can imagine marching and combat boldly, but you can't guess boldly. Instead, you must be careful to verify, otherwise the pieces of armor that will be defeated will not exist!" Zhao Bing laughed dryly after hearing this and said seriously.

"If you are arrogant, you must remember Your Majesty's teachings and dare not forget them!" Xu Wunang felt ashamed and said with a blushing face.

"You must understand that although you are in charge of a military affairs office of more than a dozen people, it is related to the lives of hundreds of thousands of soldiers in the army. Perhaps if you are not careful, you will cause my decision-making mistakes. The deaths and injuries of thousands of soldiers ahead. Therefore, you must be very cautious in your actions and never speak nonsense." Zhao Bing said a few more words.

"Your Majesty's words will be kept in mind!" Xu Wuhan was already sweating and saluted again and promised.

"Well, our army is blocked, do you have a plan?" Zhao Bing pressed his hand to let him put it down, and then asked again.

"This... I've been busy preparing for the construction of the military affairs office these days, and I'm negligent!" Xu Wunan was ashamed. As the head of military affairs, he planned the marching route and arranged warnings along the way, but now he is empty-handed and relying on guessing to do things. It's really damn.

"Go and check the documents left by Sanshiro, and you may gain something." Zhao Bing sighed lightly.
