The bizarre confrontation continued all day, until the sun went down and the scolding battle between the city and the city continued.

Yi Yun suddenly had a strange feeling in his heart, and secretly thought: What are the rebels playing? Is it really such a trick to lure the enemy by sending 500 people outside the city to provoke in every possible way, and secretly ambushing 1,500 people to raid? It seems to be the case, but how do I feel that something is strange. What is the point of this trick of luring the enemy, which will obviously be seen through by the enemy? Is the general of the rebel army so low in IQ?

He didn't know much about the ancient marches and battles, so to speak, he didn't understand them at all, so he didn't dare to give his opinions. I had to ask the civil official next to me for a piece of paper and draw a map on the paper.

Due to playing online games for many years, Eevian has participated in the battles of "World of Warcraft", the national battles of "Nobunaga's Wild Hope OL", the siege of Shabak in "Legend", the siege of "Paradise", the fortress battles of "Aion", and the interstellar offensive and defensive battles of "Eve...... Since he is a super otaku among otaku, and his game strength is also first-class, he often plays the role of commander in these major battles, and he is used to having a map to see during the war, so that it is convenient to grasp the overall situation.

Spreading out the blank paper, Yi Yun drew a large circle in the middle of the map, indicating Chengdu City, and then drew a small circle next to Chengdu City...... Each circle represents an oasis, and in a short time, the paper is filled with various circles, large and small, and their positional relationships are also reflected on the paper.

There are many small oases around Chengdu, including Meishan Oasis, Shuangliu Oasis, Pengshan Oasis, Pujiang Oasis in the south, Dujiangyan Oasis in the northwest, Deyang Oasis in the north, and Ziyang Oasis in the southeast...... These large and small oases, all located on the Chengdu Plain, are like satellite cities in the middle, and this large oasis area forms the core oasis group of the whole Sichuan...... It can be said that this is the most important area in the whole of Sichuan, and if these oases fall, the whole of Sichuan will completely collapse.

Yi Yun couldn't help but think hard, if I were the commander of this battlefield and was using voice chat software to command my troops, how could I kill all these oases in one fell swoop with just 2,000 people?

In his mind, he couldn't help but recall the common opening command method of the Okushan battlefield in "World of Warcraft": "One team and two teams guard the ice and snow, men, two thieves sneak to steal the north and south towers, four teams open the snow and fall, five teams kill women, and six, seven, eight teams follow me!"

This is a battlefield of 40 people against 40 people, with such a complex detachment and exquisiteness, if I put this kind of thinking into a 2,000-man battle, how would I defend, how to attack, how to crush the enemy?

Obviously, it was impossible for me to use all my forces to attack the enemy base camp directly at the beginning, and this move was completely foolish. I will use a small force to pin down the enemy, and then use the main force to cut into the enemy's most vital place. The most important place in Sichuan is undoubtedly the Chengdu Oasis, where it is normal to be attacked by enemy troops, but ...... Is there any other place that can be compared to Chengdu's important location?

Thinking of this, he suddenly felt a move in his heart, why did the enemy come from the west?

The rebels should have come from the south, and they also passed through Mount Emei, so logically speaking, they should have appeared at the South City Gate, why did they appear at the West City Gate now?

"Why are the rebels coming from the west?" Yi Yun suddenly raised his head and asked, "Uncle Cousin, Lord Governor, don't you think it's strange that the rebels appear in the west? They are obviously attacking from the south, they should have concentrated 2,000 men to attack our south gate, why would they use 500 men to attack the west gate?"

Yi Yun's question immediately startled the prince of Shu and Zhao Yu, and the two bigwigs glanced at each other, and a strange feeling rose in their hearts at the same time.

Yi Yun continued: "The enemy army not only came to attack the West Gate unexpectedly, but also scolded and fought with us outside the city unhurriedly, and there was no sense of urgency at all in the surprise attack, if they really wanted to break through the city of Chengdu, shouldn't they be as soon as possible? It is unusual why they are leisurely scolding and fighting with us, and putting on a picture of trying to lure us out of the city. ”

Although Zhao Yu's position as governor came through the back door, he still had some resourcefulness, he patted his head and thought about it, jumped up suddenly, and said loudly: "Divide the troops, quickly divide half of the troops to the south gate, the enemy may be feint to attack the west gate, but in fact it is the south gate that is going to attack." ”

His judgment was immediately agreed by the majority of the people, and several generals jumped up and said loudly: "That's right, the enemy army has made a feint attack on the west gate with 500 men, and gathered another 1,500 people to attack the south gate. ”

Yi Yun tilted his head and thought about it, and felt that this reason was the most reliable, so he didn't put forward any more opinions, and the governor of the three provinces took a group of subordinates and divided half of his troops to rush towards the south gate, leaving the prince of Shu on the side of the west gate.

It was dark, and the moon hung in the air. At this time, it was already autumn, and at night, it was cold and cold in the desert, and the sand cavalry outside the city were all wrapped tightly in cloaks, and while avoiding the night wind, they opened their mouths and scolded the big Meng [***] team on the city wall.

The officers and soldiers at the head of the city were also wrapped in thick cloaks, and scolded their mothers to the city with their throats shut.

This scene creates a unique aesthetic! uh...... Although this beauty is not very harmonious.

Iyun was still drawing on paper, studying the enemy's marching routes.

"Xianggong, I think you're just thinking too much. An Qian said very seriously beside her: "The enemy army is only 500 people, and our army has more than 1,000 people. ”

"No, it's not in the art of war. Li Chengyu said: "Let me explain: the enemy attacks, and we defend." Since we have a city to defend, there is no need to abandon the fortified city and run outside to fight a field battle with the enemy, we only need to clear the field with a strong wall, and wait until the enemy collapses without a fight, or the reinforcements from the periphery are encircled, which is a safe policy. ”

Yes, the art of war! Yi Yun muttered a sentence in his mouth, he always had a strange feeling, because he felt that it was impossible for the enemy to attack Chengdu so stupidly, this move was really illogical, or in Li Chengyu's words, it was not in line with the art of war. Just like what the prince of Shu said and what he saw himself, Chengdu City is a fortified city that is difficult to attack, ten meters high and ten meters thick, no matter how you think about it, it is not just a cavalry can climb up, not to mention that there are many cannons on the city wall.

If the enemy's generals knew the art of war, they would never dare to attack Chengdu, because our generals only needed to follow Li Chengyu's words about the art of war, stay in Chengdu and wait for reinforcements, and they could easily kill them.

When he got here, he suddenly jumped up, swept his eyes at the blank paper on which he had drawn the map, and said in a lost voice: "I understand! The art of war! The other side is using the wrong art of war to lure us into adopting the art of defense of war." ”

"What do you mean?" The two girls were in unison, and the prince of Shu next to him also stretched out his head and said, "Good nephew, what did you think of again?"

Yi Yun pointed his hand at the city wall and said seriously: "If you think about it carefully, we adopted the correct art of war to defend to the death, and it was entirely because the enemy's art of war was ridiculously wrong, which gave us the feeling that we could easily defeat it with the art of 'standing for help'. ”

"Yes, the enemy made a mistake, and it's normal for us to take advantage of the enemy's flaws. Lord Shu said with a smile.

"But...... The enemy's mistake was all too obvious. Yi Yun said seriously: "It's like deliberately selling it to us to catch a flaw." Let me assume that when the enemy uses this retarded tactic, he has already calculated that we will definitely stand by for help, then...... While we are waiting for help, what can the enemy do?"

"What do you do when you take the opportunity?" Lord Shu frowned: "What they can do is nothing more than to take out a few small oases around Chengdu, these small oases are usually under-armed, and they are all protected by the army stationed in the Chengdu Oasis." If we play turtle flow in the Chengdu oasis, then the small oasis on the periphery can be attacked at any time. But...... A few small oases, if you lose them, you can lose them, as long as you can surround this sand cavalry unit under the city of Chengdu, the lost small oasis can be recaptured at any time. ”

"That's right!" Yi Yun said seriously, "Just lose these little oases and take them back...... But...... There is an oasis that, once destroyed by the enemy, even if it is captured, it will not be able to return to normal operation in a short period of time. ”

"Huh?" Lord Shu raised his eyebrows: "What place are you talking about?"

Yi Yun's finger pointed to a small oasis in the northwest of Chengdu, and said with a serious face: "Dujiangyan!"

As soon as these words came out, the face of the prince of Shu changed miserably.

The Chengdu Oasis was not a very rich oasis before, and it faced a very serious problem of quicksand, which mainly came from the Minjiang River.

The Minjiang River comes from the Minshan Mountain Range, flows south from the west side of the Chengdu Plain, and is an authentic above-ground hanging river for the entire Chengdu Plain, and it hangs very much. Whenever the quicksand of the Minjiang River rises and floods, the quicksand will ravage the Chengdu Plain, causing a terrible scene of thousands of miles of red land.

Later, there was a genius in Dameng country, named Li Bing, who was more than 100 miles northwest of Chengdu, and selected the location where the Minjiang River had just flowed out of the mountain into the plain, and built the Dujiangyan Shali Project. This sand project divides the quicksand in the Minjiang River into two, one part still flowing along the Minjiang River, and the other part uses the diversion of the fish's mouth and the mouth of the treasure bottle to divert the water into the Tuojiang River.

In this way, the quicksand that has plagued the Chengdu Plain for a long time has been solved, and the Chengdu Oasis has grown more and more, forming a prosperous scale with a radius of hundreds of miles.

If...... If the enemy blows up Dujiangyan...... Clogged bottle mouth...... Then, the surging quicksand will strike again, rolling up the Chengdu Plain, the core hinterland of Sichuan, will be stirred by the quicksand again.
