The boy hesitated.

It stands to reason that they only obey the orders of His Majesty alone, and cannot do things for others.

However, before coming, His Majesty said that they should all obey the orders of the concubine and not be allowed to disobey.

"What do you command?" Let's listen to Xu Shu's request first.

"I've had some intersections with the Nancheng Cao Gang in the past few months, you help me arrest that Zhang Mi of the Cao Gang."

The young man pondered for a moment, this was not a big deal, it was just an inconsequential figure of the Nancheng Cao Gang.

After he left, Lu Yijun was a little confused.

"What's your connection with the Cao Gang?"

The Cao Gang is in charge of Cao Yun, she belongs to her to make money, and there is no intersection between the two sides.

Could it be that someone is in the way of her wealth?

Xu Shu leaned on the couch.

"Don't forget, the geographical location of Nancheng, but the thoroughfare of the nine cities, how important is the transportation of such a place."

Lu Yijun's first reaction was: "Who said that Nancheng is just an ordinary medium-sized city that can't be ordinary anymore, how can it be the thoroughfare of the Nine Cities?" ”

If it is really the thoroughfare of the nine cities, let alone him, His Majesty will definitely attach great importance to it.

However, Nancheng is surrounded by mountains on three sides, and there is only one waterway connected to the outside, which is almost semi-closed.

Xu Shu recalled in his mind a topographic map he had seen in Xie Lin'an's upper study.

"When there is no war, Nancheng is naturally a small closed city, but if you think about it, once the war is imminent, Haihu City in the west will definitely cut off all contact with the outside world and trap itself as an island, so if the army wants to advance eastward, it must cross the Qiangwu Mountain and pass through Nancheng."

Lu Yijun's face could no longer be described as shocked, "Why do you know?" ”

Haihu City is indeed a military powerhouse, and it was also his idea to close the city gate and become a lonely city when the battle was about to go, but he never said it to anyone, if Xu Shu guessed it, it would be a bit too unbelievable.

Such an outrageous tactic, Xie Lin'an almost rejected it at that time, how could Xu Shu have thought of it.

"Haihu City is a military powerhouse, first of all, don't say that there are 100,000 heavy soldiers, just say that your armament nest should be here. If it were me, I would have made this place impregnable, and then the enemy would have chosen to bypass this strong fortress first, and they would definitely want to wait until the other cities had scavenged enough food and grass before coming back to attack here. What you calculated was that this time difference was enough for Haihu City and other cities to form a line of defense and directly cut off the rear road of the enemy's army. ”

Lu Yijun was completely shocked by her.

"So ......"

Xu Shu nodded: "In the same way, the same is true for several other cities, all of which have a special role in wartime, so in the end, they can only pass through the southern city, which will be the most important transportation fortress." ”

"And you want to attack the Cao Gang because you want to control the water transportation in the southern city?" Lu Yijun asked.

"We can't talk about control," Xu Shu changed his posture and lay down, "but if we can occupy a place in Nancheng Caoyun, we will have a say in the traffic control of the entire Xihai." ”

Lu Yijun was obviously particularly excited about this discovery, almost to the point of fidgeting.

Xu Shu still thinks that in terms of interest in this kind of military strategy, men far surpass women.

She felt that her head was big just thinking about these things some time ago, but Lu Yijun felt very excited, and she couldn't wait to go back to Qin Yu and Xie Lin'an to talk at night.
