Thirty miles south of the hanging gourd, in the military camp on the bank of the Rushui River, He Ruobi looked at a few pieces of paper in his hand, and then looked to the north, even if he was in the plain at this time, it was impossible for him to see the hanging gourd thirty miles away with the naked eye.

Thirty miles is a day's march of the great army, neither near nor far.

If you use a clairvoyant mirror to look at the Hanging Gourd, you can barely see a small outline, but outside the Hanging Gourd City, there is a long fence built by the enemy, and there is an enemy camp outside the long fence, and the other party also sent many cavalry to wander in the wilderness, and it is impossible for your own cavalry to get close to the city to deliver news.

And now, the impossible has become possible.

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

The Hulin Army, which was walking with the soldiers and horses under his jurisdiction, used an incredible way, separated by a distance of thirty miles, to exchange news with the defenders of the Hanging Fortress City out of thin air, and Yuwen Wenwen, the king of Xiyang who was sitting in the Hanging Fortress, already knew the current situation, and the other party also passed on the situation of the besieging enemy army.

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

He Ruobi followed the herald into the big tent, only to see a huge schematic map hanging in the tent, which depicted the enemy's defense around the hanging gourd.

Unless it's a secret that has been discovered in detail, otherwise why is it so detailed?

He Ruobi thought so, this was his first thought after seeing this schematic diagram, and he couldn't help but think so, because the schematic diagram was too detailed, not only the directions of various large and small camps, but also the patrol rules of the enemy's cavalry on weekdays.

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

The enemy first dug a circle of trenches around the hanging gourd, and then used the soil obtained from the trenches to build a long circle, which was like a dike, and the blocking of the trenches, the defenders of the hanging gourd wanted to climb over the obstacles, and it was necessary to make a lot of effort.

Even if you climb over the long fence, there are wooden stakes outside the long fence, which are densely shaped like a stake array, which can slow down the speed of the cavalry, and the cavalry patrolling the perimeter can calmly surround the hanging cavalry trying to break through.

The enemy army besieged the city, with more than 100,000 troops, divided into four battalions in the east, south, west, and north, respectively set up a village in the southeast, northwest, and northwest directions of the long siege, with an average of 30,000 or 40,000 people in each large battalion, and the camp defense has been strengthened recently, and there are antlers on the periphery, which is difficult to break through in a hurry.

The enemy's southern camp and Beida camp are located on the bank of the Rushui River, the northern camp is where the Chinese army is located, the puppet emperor is in the northern camp, and the southern camp has a barrage, and now the sluice gate has been closed to store water, so that the water level outside the city began to rise.

The enemy's move is to completely trap the defenders of the Hanging Gourd, although it has passed the first day, but the weather is still cold, the water level of Rushui rises, flooding the ground outside the Hanging Gourd City, even if the water level is not deep, but it is easy to freeze, and the defenders will not be able to rush out at all, and the reinforcements will come inside and outside.

There is also another possibility for the enemy to store water, that is, when the water level rises to a certain height, open the sluice gate and release the water, and then carry out a water attack on the army in the lower reaches of the Rushui.

"Now is the dry season, the amount of water in you is insufficient, and the other party wants to store water, I am afraid it will take a long time."

"They don't necessarily store water for water attack, as long as the water level overflows the land outside the Hanging Gourd City, when the time comes, it will freeze, and people and horses will slip when they walk on it, where can they break through to the outside."

"The trench has been widened, the horses can't jump over, the long fence is splashed with water, it freezes overnight, it can't slip, it's difficult for the defenders to break through, so how can they be combined inside and outside, and come to an internal and external attack?"

The generals discussed, He Ruobi frowned, looked at the schematic diagram and fell into thought, everyone's opinion was right, since the enemy dared to let them approach the hanging gourd, they must be prepared.

Knowing that the other side could survive a hundred battles, He Ruobi initially planned to send cavalry, regardless of casualties, to find out the general situation of the besieging enemy army, so as to provide a basis for decision-making.

And now, with little effort, he figured out the enemy's defenses, and although he was relieved, he felt heavy.

The enemy surrounded the Hanging Gourd to death, and it was basically impossible for the defenders to effectively break through, so the strategy of 'internal and external attack' that they had drawn up before would definitely not work, and they would be easy to come thirty miles outside the Hanging Gourd City, but it would not be so easy to leave.

In the battle of Chai Village, Wei Chi turned into seven or eight thousand cavalry, but the other party had a strong foundation and could afford to lose, and then the other party abandoned Song Ping and let his own army move north to approach the hanging gourd, of course, he was not frightened.

He Ruobi knew that the other party was going to besiege the city and send reinforcements, so he specially let them approach the Hanging Gourd, so that he thought that he could take advantage of the opportunity to fight inside and outside the decisive battle with the defenders of the Hanging Gourd, and now that they wanted to leave, Wei Chidun would not sit idly by.

Since he dared to come to the hanging gourd, He Ruobi knew that he would inevitably face such a dilemma, and he would not be afraid, but he wanted to know what decision Xiyang Wang Yuwenwen would make in such a situation.

He Ruobi was pondering, and Yuwen Fifteen on the side was also pondering, he was the supervising army, not the commander, and this coalition army actually had no real commander, because the 'predetermined' commander was in the Hanging Fortress City, and when King Yu Wenming sent various troops and horses to jointly attack, he repeatedly emphasized this point.

The Hulin Army is the private army of the King of Xiyang, except for himself, perhaps only the King of Qi or the prince of the King of Qi can personally command, and others are not qualified to be the commander of the Hulin Army, so since arriving in Guangcheng, the combat strategy of the coalition army has been discussed by the generals of various departments.

As a result of the discussion, the minority obeyed the majority, and everyone fought according to the agreed strategy, and if everyone could not argue, it was Yuwen 15 who made the choice.

When the siege of the Hanging Gourd is relieved, the generals of all the departments of the coalition army must listen to the command of the King of Xiyang, and now the King of Xiyang is in the Hanging Fortress City, and there are thirty miles between the reinforcements, as well as trenches, long encirclements, and enemy blocks, and it is impossible for the two sides to be able to get in touch.

However, with the incredible "Xishanai" device, the impossible has become possible, and the king of Xiyang, who is thirty miles away, can directly command the army outside the city.

Yuwen Fifteen has some emotion about this, Yuwen Wen is his master, and the means of making money are very good, if it is not for the difficult situation, he must spend a huge amount of money to maintain a strong army, and the money Yuwen Wen has earned over the years is enough for future generations to live a chic life.

In addition to raising soldiers, Yuwen Wen also spent a lot of money to 'research and develop' all kinds of strange devices, the cost of which far exceeded the need to maintain the combat strength of the Tiger Forest Army, Yuwen Fifteen has always been unable to understand this, and now after experiencing the benefits of 'Xishan Ai', he knows the good intentions of Lord Lang.

At this time, Wei Chidun was afraid that he thought that he had a plan, thinking that he could isolate the inside and outside of the hanging gourd, so that the defenders and reinforcements could not communicate the news, and then they were broken one by one, but they did not know that they used an incredible way to contact each other and cooperate in combat.

The sound of footsteps started, several soldiers walked into the big tent, one of them handed the paper with words written in his hand to Yuwen 15, Yuwen 15 carefully read it, came to the schematic diagram, and faced the generals.

"Silence!"

"The king has an order, read it now!"
