Thirty miles south of the Xuanhu, in the military camp by the Rushui River, He Ruobi looked at the few pieces of paper in his hand and looked north. Even if he was in the plain at this time, he could not see the Xuanhu thirty miles away with his naked eyes.

Thirty miles is the journey of a large army for a day, neither near nor far.

If you look at Xuanhu with a thousand-mile mirror, you can probably barely see a small outline. Outside Xuanhu City, there is a long circumference built by the enemy. There is an enemy camp outside the Changhu City. The opponent also sent many cavalry to wander in the wilderness. It is impossible for the cavalry on his side to get close to the city to convey messages.

And now, the impossible becomes possible.

The paper in He Ruobi's hand recorded the news from Xuanhu City. He couldn't believe it was true, but he had to believe it was true.

The Hulin Army, who was walking with the troops under his command, communicated information with the defenders of Xuanhu City out of thin air, in an incredible way, across thirty miles apart. The King Yuwen of Xiyang, who was in charge of Xuanhu, had already known the current situation, and the other party also spread the situation of the enemy siege.

"General He Ruo, the diagram has been drawn, please enter the account."

He Ruobi followed the commander into the tent and saw a huge diagram hanging in the tent. The enemy's defense situation around Xuanhu was drawn on it. He Ruobi and other generals gathered in front of the map and looked at it carefully.

Could it be that it was a secret found in detail, otherwise why is it so detailed?

He Ruobi thought so, this was his first thought after seeing this diagram. He couldn't help but think so, because the diagram was too detailed, not only did it have the locations of various large and small camps, but even the patrol rules of the enemy's cavalry on weekdays were marked.

Of course, this is just a conclusion drawn after rough statistics. He Ruobi looked carefully at the schematic diagram and found that Xuanhu had been surrounded by the enemy, and it was very difficult for the soldiers in the city to break through.

The enemy first dug a circle of trenches outside Xuanhu, and then built a circle of long encirclements with the soil obtained from digging the trenches. The long encirclement was like a dam, and with the obstruction of the trenches, the Xuanhu defender would have to spend some effort to cross the obstacles.

Even if you turn over the long encirclement, there are still wooden stakes outside the long encirclement, which are densely packed like wooden stake formations, which can slow down the speed of the cavalry. The cavalry patrolling the outside can calmly encircle the Xuanhu cavalry trying to break through.

The enemy's army besieged the city with more than 100,000 troops, divided into four major camps in the east, south, west and north. They set up camps in four directions of Changwei, south, west and north. On average, each camp has 30,000 to 40,000 people. The camp defense has been strengthened recently, and there are deer antlers on the periphery, which is difficult to break through in a hurry.

The enemy's Nandaying and Beidaying are located on the banks of the Rushui River. Beidaying is the central army. The pseudo-Emperor is in Beidaying, and a river dam is built in Nandaying. Now the gates are closed to store water, causing the water level outside the Xuanhu City to begin to rise.

The enemy's move was to completely trap the Xuanhu defender. Although the New Year's Day has passed, the weather is still cold. The Rushui water level has risen and flooded the ground outside the Xuanhu City. Even if the water level is not deep, it is easy to freeze. At that time, the defenders will not be able to rush out at all and cooperate with reinforcements inside and outside.

There is another possibility for the enemy to store water, that is, when the water level rises to a certain height, open the gate and release the water, you can launch a water attack on the army downstream of the Ru River.

"It's the dry season now, and the amount of Ru water is insufficient. It may take a long time for the other party to store water."

"They stored water not necessarily for water attack. As long as the water level overflows the land outside Xuanhu City, it will freeze when the time comes, and people and horses will slip when they walk on it, so where can they break out?"

"The trench has been widened and even the horse can't jump over it. The long encirclement has poured water again. It will freeze overnight and it will not slip. It will be difficult for the defenders to break through. In this way, how can they cooperate with the inside and outside and attack inside and outside?"

The generals were talking, and He Ruobi frowned and fell into deep thought as he looked at the diagram. Everyone's opinion was right. Since the enemy dared to let them approach Xuanhu, they would definitely be ready.

Only by knowing oneself and the other can one be defeated in a hundred battles. He Ruobi initially planned to send cavalry to approach Xuanhu regardless of casualties and find ways to find out the general situation of the enemy's besieged in the city so as to provide a basis for making decisions.

Now, he found out the enemy's defense situation without any effort. Although he felt relieved, he felt heavy.

The enemy surrounded Xuanhu to death, and the defenders could not effectively break through. Then the "internal and external attack" strategy that they had formulated before would definitely not work. However, it was easy for them to come thirty miles outside Xuanhu City, but it was not so easy for them to leave.

In the Battle of Chai Village, Yuchi Dun turned in seven or eight thousand cavalry, but the other party had a strong family and could afford to lose. Then the other party abandoned Song Ping and allowed his troops to move north to approach Xuanhu, which was certainly not scared.

He Ruobi knew that the other party was going to siege the city and attack the aid, so he specially asked them to approach Xuanhu, so that he thought he could have an opportunity to take advantage of it, and attacked both inside and outside in the decisive battle with Xuanhu's defenders. Now that they wanted to leave, Yuchi Dun would not sit idly by.

Since he dared to come to Xuanhu, He Ruobi knew that his side would inevitably face such a dilemma and he would not be afraid, but he wanted to know what decision would be made by King Yuwen of Xiyang under such circumstances.

He Ruobi was pondering, and Yuwen Shiwu, who was beside him, was also pondering that he was a military supervisor, not a commander, and this coalition actually had no real commander, because the "reserved" commander was in Xuanhu City. When the prince of Qi, Yu Wenming, sent troops and horses to attack together, he repeatedly emphasized this point.

The Hulin Army is the private army of the King of Xiyang. Apart from him, perhaps only King Qi or Prince Qi can command it himself. Others are not qualified to be the head coach of the Hulin Army. Therefore, since arriving in Guangcheng, the combat strategies of the coalition forces have been discussed together by generals from various departments.

As a result of the negotiation, the minority obeys the majority, and everyone fights according to the agreed strategy. If everyone can’t argue, Yuwen Shiwu will make the choice.

After the siege of Xuanhu was lifted, the generals of all coalition forces had to obey the command of King Xiyang. Now the King Xiyang is in Xuanhu City, with thirty miles between them and reinforcements, and there are trenches and long encirclements, and the enemy blocks them. It was impossible for the two sides to be able to contact each other.

However, with the incredible "Xishan Ai" device, it is impossible to become possible. The King of Xiyang, who is thirty miles away, can directly command the army outside the city.

Yuwen Shiwu was a little moved by this. Yuwen Wen was his husband and had great ways to make money. If the situation was not difficult, he would have to spend a huge amount of money to maintain a strong army. The money Yuwen Wen earned over the years would be enough for his descendants to live a free life.

In addition to raising troops, Yuwen Wen also spent a lot of money to "develop" various strange devices, which cost far more than needed to maintain the combat effectiveness of the Hulin Army. Yuwen Shiwu has always been unable to understand this. Now that he has experienced the benefits of "Xishan Ai" in his own way, he knows the good intentions of the Langzhu.

At this time, Yuchi Dun was afraid that he could have a plan, thinking that he could isolate the inside and outside of Xuanhu, so that the defenders and reinforcements could not communicate with each other, and then they were defeated one by one. However, he knew that his side contacted each other and fought in an incredible way.

Footsteps sounded, and several soldiers walked into the tent. One of them handed the paper with words in his hand to Yuwen Shiwu. After Yuwen Shiwu looked carefully, he came to the diagram and faced the generals.

"quiet!"
