The strange confrontation lasted all day until the sun set and the verbal battles continued on the city.

Yi Yun suddenly felt a little strange in his heart, thinking to himself: What is the rebels playing? Send 500 people to provoke outside the city and secretly hiding 1,500 people to attack. Is it really such an enemy plan? It seems like this, but why do I feel that something is strange? What is the meaning of this enemy plan that will be clearly seen by the enemy? Is the general of the rebel army so low?

He didn't know much about ancient marches and wars, so he didn't understand them at all, so he didn't dare to give any suggestions. He had to ask the civil servant next to him for a piece of paper and draw a map on the paper.

Due to years of playing online games, Yi Yun has participated in the battle of "World of Warcraft", the national battle of "Nobunaga's Ambition", the Sabak siege in "Legend", the siege in "Paradise", the fortress battle in "Tower of Eternity", and the interstellar offensive and defensive battle in "Eve"... Because he is a super otakus among the otakus and his game strength is also first-class, he often acts as a commander's corner during these major battles. He is used to having a map to see during wars, so that he can easily grasp the overall situation.

Spreading out the white paper, Yi Yun drew a large circle in the middle of the map to represent Chengdu City, and then drew a small circle next to Chengdu City... Each small circle represents an oasis. In a short while, various circles of large and small were painted on the paper, and their positional relationship was also reflected on the paper.

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

Yi Yun couldn't help but think hard. If I were the commander of this battlefield and were commanding my troops with voice chat software, how could I kill all these oasis with just 2,000 people?

In his mind, he couldn't help but recall the common starting command method of the Aoshan battlefield in World of Warcraft: "First team and two teams guard the ice and snow, men, two thieves sneaked around the north and south towers, four teams drive snow fall. Fifth teams kill women, six, seven and eight teams come with me!"

This is a battlefield between 40 people and 40 people, so there are such complex teams and requirements. If I put this idea into a major battle of 2,000 people, how will I defend, attack, and defeat the enemy?

It is obvious that I cannot use all my troops to directly attack the enemy base camp from the beginning. This action is completely a fool. I will use a small group of troops to restrain the enemy like I am fighting the Aoshan battlefield, and then use the main force to cut into the enemy's most important place. The most important place in Sichuan is undoubtedly the Chengdu Oasis. It is normal to be attacked by enemy troops here, but... Is there any place that can be compared with Chengdu?

Thinking of this, he suddenly felt aroused his heart. Why did the enemy come from the west?

The rebels should have come from the south! They passed by Mount Emei. Logically speaking, they should have appeared at the south city gate. Why are they now appearing at the west city gate?

"Why did the rebels come from the west?" Yi Yun suddenly raised his head and asked, "Cousin, Governor, don't you think it's strange that the rebels appear in the west? They obviously attacked from the south. They should have concentrated two thousand people to attack our South Gate. Why did they use five hundred people to attack the West Gate?"

Yi Yun's question immediately scared Prince Shu and Zhao Yu. The two bigwigs looked at each other and felt a strange feeling in their hearts at the same time.

Yi Yun continued: "The enemy not only came to attack Ximen incredibly, but also fought against us outside the city slowly. There was no sense of urgency for the surprise attack. If they really wanted to break through Chengdu City, wouldn't it be better? As long as we were given a few days, reinforcements would be sent in each nearby county town. At that time, they would be killed. Why did they fight against us leisurely and show that we were about to leave the city? This is really unusual."

Although Zhao Yu's position as the governor came through the back door, he still had some intelligence. He patted his head and thought for a while, jumped up suddenly, and shouted: "Divid the troops, divide half of the troops to go to the south gate. The enemy may be a feint attack on the west gate, but in fact he is going to attack the south gate."

His judgment was immediately approved by most people. Several generals jumped up and shouted: "That's right, the enemy used 500 people to attack the West Gate and gathered another 1,500 people to attack the South Gate. It must be like this. Now the sky is already dark, which is just conducive to the surprise attack. The rebels may launch an offensive immediately! Let's divide our troops to defend the South Gate."

Yi Yun tilted his head and thought about it, and thought that this reason was the most reliable, so he did not give any more opinions. The governor of the three provinces led a group of subordinates and divided half of his troops to pounce on the south gate, leaving the Prince of Shu at the west gate.

It was dark and the bright moon hung in the air. It was already autumn. At night, the desert was cold and cold. All the sand cavalry outside the city wrapped their bodies tightly in their cloaks. While avoiding the night wind, they opened their mouths to curse the big cute team on the city wall.

The officers and soldiers on the top of the city were also wrapped in thick cloaks and cursed at the bottom of the city with their throats.

This scene forms a unique beauty! Uh...although this beauty is not very harmonious.

Yi Yun was still drawing around on paper, studying the enemy's marching route.

"My husband, I think you are just thinking too much." An Qian said seriously next to her: "There are only 500 enemy troops, and our army has more than 1,000 people. Just rush out of the city and kill them all? Why are you writing and drawing on paper?"

"No, this is not in line with the military strategy." Li Chengyu said, "Let me explain it: the enemy attacks, and we defend. Since we have a city to defend, there is no need to abandon the city and run outside to fight the enemy in the field. You only need to firmly clear the walls and clear the field. When the enemy collapses without fighting, or reinforcements from the outside are encircled, this is the perfect and safe plan."

Yes, military tactics! Yi Yun murmured, and he always had a strange feeling, because he felt that the enemy could not attack Chengdu so stupidly. This move was really illogical, or in Li Chengyu's words, it was not in line with military tactics. Just like what the Prince of Shu said and the scene he saw himself, Chengdu City is a hard-to-attack city, with a wall of ten meters high and a thickness of ten meters. No matter how you think about it, it was not something that only cavalry could climb up, let alone many cannons were installed on the wall.

If the enemy generals understand the military tactics, they will never dare to attack Chengdu, because our generals only need to follow the military tactics mentioned by Li Chengyu and wait for reinforcements in Chengdu to easily kill them.

When he got here, he suddenly jumped up suddenly, swept the white paper he drew with his eyes, and said in a lost voice: "I understand! Military Art! The opponent is using the wrong military art to lead you to use the defensive military art."

"What does it mean?" The two women were stunned, and the Prince 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: "Look at it carefully. We use the correct military strategy of defending the enemy. It is entirely because the enemy's military strategy is wrong, which gives us the feeling of being able to easily defeat it by "guarding to wait for assistance."

"Yes, the enemy made a mistake. It is normal for us to seize the enemy's flaws and exploit them." Prince Shu smiled.

"But... the enemy made this mistake too obvious." Yi Yun said seriously: "It's like selling it to us on purpose to catch flaws. Let me assume that when the enemy uses this mentally retarded tactic, we have already calculated that we will definitely defend and wait for assistance. Then... while we guard and wait for assistance, what can the enemy take the opportunity to do?"

"What to do?" Prince Shu frowned: "What they can take the opportunity to do is to remove several small oasis around Chengdu. These small oasis are usually insufficient in military strength and are protected by the army stationed in Chengdu Oasis. If we play turtle streams in Chengdu Oasis, then the small oasis on the periphery may be attacked at any time. However... a few small oasis will be lost if they are lost. As long as the sand cavalry unit can be encircled to death under the city of Chengdu, the lost small oasis can be recaptured at any time."

"That's right!" Yi Yun said seriously: "If these small oasis are lost, they can be taken back... But... there is an oasis that once it is destroyed by the enemy, even if it is taken back, it will not be able to resume normal operation in a short period of time."

"Huh?" Prince Shu raised his eyebrows: "Where are you talking about?"

Yi Yun pointed his finger at a small oasis northwest of Chengdu, and said seriously: "Dujiangyan!"

As soon as this sentence was spoken, the Prince of Shu changed his face.

Chengdu Oasis was not a very rich oasis before. It faced very serious damage to quicksand, and these quicksands mainly came from the Minjiang River.

The Minjiang River comes from the Minshan Mountains and flows south from the west side of the Chengdu Plain. For the entire Chengdu Plain, it is an authentic river hanging on the ground, and it is very hanging. Whenever the Minjiang River rises and floods, the quicksand will rage the Chengdu Plain, causing a terrible scene of thousands of miles of barren land.

Later, a genius named Li Bing appeared in Dameng Kingdom. He chose the location where the Minjiang River had just flowed out of the mountain and flowed into the plains, and built the Dujiangyan Shali Project. This Shali Project divided the quicksand in the Minjiang River into two parts, one part still flowing along the Minjiang River, and the other part used the diversion of the fish mouth and the Baoping mouth to divide the water into the Tuojiang River.

As a result, the quicksand that had long plagued the Chengdu Plain was solved, and the Chengdu Oasis grew and grew stronger and stronger, forming a prosperous large-scale scale of hundreds of miles.
