"What kind of tactic is this, I'm also a person who has studied the art of war, and this is the first time I've heard of this mobile defense." Zhang Yu's big eyes revealed doubt.

Lu Zhan first sold Guan Zi to Zhang Yu, "Yu'er, do you remember that there is a girl named Luo Yuechan in my house?" ”

"Of course I know, isn't it just the fall of the sinking fish and the geese. Why, she is still a master of the art of war? ”

"Not really, but something she said while playing chess reminded me that it's better to be defensive than aggressive."

Before Zhang Yu could speak, Xiao Yezi couldn't help but ask: "Young Master, that's the Jin Kingdom, it's more difficult for us to even defend, and we still take the initiative to attack." Won't this be"

After hearing Xiao Yezi's words, Lu Zhan pointed to a place on the map that was circled by a brush - Shucheng. Just now, Lu Zhan had been studying the terrain and the information sent over in the study, and after careful consideration, Lu Zhan concluded that the place where the Jin Guo Zhi clan hoarded grain, grass and siege equipment was in Shucheng.

Zhang Yu saw that the Shucheng encircled by Lu Zhan was indeed convenient for the transfer of grain and grass, and it was convenient to supply grain and grass from the waterway with the back of the big river, and there were many cities to block it from Yanzhou, so it was an excellent choice to use it as a logistics support base for attacking Yanzhou.

"Lu Zhan, do you want to destroy the grain and grass equipment in Shucheng before the Zhi clan gathers heavy troops?" Zhang Yu said his inner guess.

"That's right, this Shucheng is the target of my sneak attack." Sure enough, Zhang Yu is a rare strange woman in the world, and based on Shucheng who was circled and her own judgment, she decided that Shucheng was the target.

"This is called mobile defense?"

"Of course not, one of the meanings of mobile defense is to replace defense with offense, and keep the enemy out of the country. We use cavalry and other mobile combat forces to shrink the defensive line while fighting on the outside line, so that the enemy can penetrate into our encirclement, and finally close the door and fight the dogs. Lu Zhan explained the concept of mobile defense, and mobile defense should be the best way to do it.

If the Zhi clan still insisted on mobilizing troops after destroying Shucheng's baggage, they first pretended to retreat to attract the main force of the Zhi clan, and then cut off the retreat, and the retreat route was blocked and the supply was cut off, and these soldiers would definitely not be able to hold on. The famous general of the Southern Song Dynasty in history, Meng Heng, is a master who is good at mobile defense.

"It seems that you have even thought of a plan, can you take me, a little woman, on your trip to Shucheng?" Zhang Yu ruffled his hair and said to Landing Zhan.

"Brother Zhang Wangdian is willing to appreciate the light, so he is naturally grateful, and he will gather his troops and set off early tomorrow morning." Afterwards, Lu Zhan went to the barracks to inform Chen Zhuang that he was ready to leave.

Before entering the council hall, Lu Zhan saw that the soldiers who had been trained were even more confident, these new troops were well-disciplined and well-trained, although the scale was not large, but it was enough.

After hearing Lu Zhan's plan, Chen Zhuang couldn't help but say: "This is really too risky, besides, after the autumn harvest, there will definitely be a large amount of new grain to replenish into the granary."

"General Chen only knows one thing but doesn't know the other, it is true that according to our plan, there are indeed problems you said, but after the autumn harvest, the Zhi family will definitely be ready to do it, and Shucheng will definitely be heavily guarded at that time. Moreover, it is difficult to transfer new grain after the autumn harvest to the front in a short period of time, and it is simply impossible. Lu Zhan opened his mouth to dispel Chen Zhuang's doubts.

Chen Zhuang took advantage of Lu Zhan's words and said: "The last general of the lord knows that if the Zhi family can't wait to collect grain and grass to supply the army, it will inevitably damage the interests of the local people. If the Zhi family waited until the grain and grass were transported before moving the troops into winter, the morale of the soldiers in winter would inevitably be low. What's more, even if the two thousand people of the Lu family's own family come slowly, they will definitely arrive before winter. ”

"So I mobilized all the troops to secretly go to the vicinity of Shucheng, and asked Wen to send a part of the men to our barracks to pretend that we were still in the barracks, and the family said that I was sick and could not see guests. As for the family's 2,000 men, they should all be in place within a month. Lu Zhan began to explain the specific details of his heart.

After hearing Lu Zhan's bold plan, Wen Yishi also nodded in agreement, and also said that he could transfer three hundred elite cavalry to help in the battle.

Cavalry has always been scarce, and the 300 people who heard about it, plus Zhang Yu's government soldiers and his own more than 1,000 cavalry, a total of 1,005 people. The cavalry is responsible for the sneak attack on Shucheng, and after Shucheng is attacked, the Zhijia will inevitably pursue the cavalry, and the cavalry will inevitably be caught up when the cavalry is sleepy and tired, and the infantry who came as the main force is ready to meet the cavalry.

After reading these plans, Lu Zhan began to admire his wisdom, and when he returned home, he told Jing Nianshuang about things. Seeing that her husband was going out again, Jing Nianshuang began to sigh again.

Duan Xiaohan immediately got ready when he heard the news that Lu Zhan was going to take him out to fight, and Duan Xiaohan, who was about to clean up, suddenly asked: "Why did we take the cavalry to attack Shucheng, and it would be much better to bring all the brothers to capture Shucheng."

"Xiaohan, if according to what you say, so many of our brothers go to Shucheng, then Yanzhou will not be empty of guards. Besides, the cavalry has strong mobility and runs after the fight, coming like falling from the sky, and going like lightning. Not to mention the concealment of so many people, if the infantry went to Shucheng, I am afraid they would not be able to get out, so the infantry could only come to respond. "Duan Xiaohan really has been mixed up in the rivers and lakes for a long time, and he doesn't have the wisdom of marching and fighting in his head, so it seems that Duan Xiaohan is still arranged in intelligence and spy work.

Early in the morning, the people who stayed in the barracks saw Wen Yishi come to the barracks with his troops, and according to the agreement, the soldiers brought by Wen Baishi were stationed here to confuse the outside world. More than 7,000 troops quietly left at night, and the soldiers went into the mountains with dry rations to endure mosquito bites.

The next day, Wang Zhuji, who was about to go to the Lu Mansion to discuss things, walked to the door and was told that Lu Zhan was sick and could not see guests, and in the afternoon, many people sent various supplements and medicines one after another. Xiao Ye of the family instructed the guys in the family to put these gifts into the warehouse.

"Thanks to these brothers from Orion who led the way, after passing through so many mountains, there should be Shucheng in front of you." Lu Zhan said after looking at the map.

"Lord, the brothers in Shucheng have sent news that part of the grain and grass in Shucheng is stored in the treasury of Shucheng, and most of them are in the army camp outside the city." Duan Xiaohan scratched the arm that was bitten by the mosquito and said to the landing exhibition.

At this time, Chen Zhuang asked, "Then should we just sneak attack the camp outside the city?"

"We don't know how much grain and grass is stored in Shucheng, so we must burn this grain and grass hidden in the city." Lu Zhan looked worriedly in the direction of Shucheng.

"But isn't it very difficult for the cavalry to attack the city, and we will definitely be able to burn the grain and grass of the camp outside the city with the advantage of the cavalry and the surprise attack." Chen Zhuang still didn't want to take such a big risk to attack Shucheng directly.

"Do you still remember the method of sneaking up on the city gate in the capital, this time Duan Xiaohan will sneak into Shucheng in batches with a group of capable brothers, but what we want is to do it during the day."
