"Mr. Li, why did you let him go?"

It didn't take long for Song Qing to deal with the outside affairs, and on the way to come, he happened to meet Hu Dahai who was released, and after asking about it, he learned that Li Gengyun had released him, and he didn't ask too much, so he came to the prison to meet Li Gengyun and talked about the release of Hu Dahai.

"Brother, this is nothing, Brother Yun said that he would attack Xianyang Pass!"

"Hit the show Yang Guan?!"

Hearing what He Jin said, Song Qing's expression was exactly the same as the expression He Jin had when he heard that Li Gengyun was going to play Xianyang Pass before, he looked at Li Gengyun in surprise, and couldn't help but reach out and touch the other party's forehead and asked, "Mr. Li, you don't have a fever, do you?" What's the confusion? We only have 1,000 soldiers and horses, and we are going to fight Xianyang Pass, do you know how many Yuan troops there are in Xianyang Pass? ”

"Of course I do! There were still 20,000 troops left in Xianyang Pass, of which 3,000 were wolf knights, 5,000 archers, 5,000 cavalry, and 7,000 infantry. The leader of the troops was Qian Yuan, known as the four generals of Yuntian. ”

Li Gengyun was very calm when answering Song Qing's question, and he asked back with a smile: "General Song is afraid?" ”

"Hehe, Mr. Li laughed, 1,000 people against 20,000 troops, that is, ants shaking the tree mantis arm as a car, purely to send to death! Isn't Mr. Li crazy? ”

Song Qing didn't consider Li Gengyun's question at all, I'm afraid that this is not a prerequisite, and this is not a multiple-choice question but a proposition. 1,000 people fighting the Xianyang Pass, which is garrisoned by 20,000 military horses, is to die.

"That's right, I'm just going to fight Xianyang Pass, is General Song willing to accompany me to death?"

"This ......"

Seeing Li Gengyun's serious eyes, Song Qing also hesitated, the strategy set by Li Gengyun before had worked, and the eight hundred soldiers led by Hu Dahai and the two hundred wolf knights who arrived ahead of schedule all relied on Li Gengyun's strategy to win smoothly. Song Qing originally thought that Li Gengyun would choose to stick to Pingyang Pass, but he didn't expect that the other party would choose to attack Xianyang Pass.

"Mr. Li has a plan?"

Since Li Gengyun was so sure, Song Qing also thought of it, he must have thought of a perfect plan, otherwise he would not have planned to do so, with only 1,000 people to attack Xianyang Pass, which has 20,000 people.

"How can there be a plan that is not perfect, only to say, it can only be said that step by step is a success. Is there a map of Lizhou? ”

"Yes! Then let's go to the General's Palace! ”

"Okay!"

The group of three came to the General's Mansion, and Song Qing took out a small sand table from the mansion, which simulated the terrain around Pingyang Pass and several nearby checkpoint cities. On the back wall of the living room, there is also a map of Lizhou's military distribution, which is just right for Li Gengyun to guide the planning.

"This is Pingyang Pass, here is Xianyang Pass, and this is West Malaysia City. The distance between Pingyang Pass and Xianyang Pass is more than 100 miles, while Xima City and Xianyang Pass are 80 miles apart, and Xima City and Pingyang Pass are 120 miles apart. ”

Song Qing told Li Gengyun the distance between the three cities on the sand table, and then he pointed to the map on the back wall and continued: "Mr. Li, the military distribution map of Lizhou, but this is the military distribution of the Great Song Dynasty. ”

"Well, there are still 20,000 troops left in Xianyang Pass, and the 30,000 troops of Xima City and the 20,000 Song army are facing off, it should be a protracted battle, and if there are no reinforcements, it will take at least two days for the Yuan army to capture Xima City. Within two days, the 30,000 Yuan Army could not be mobilized. Li Gengyun picked up the two small flags on the side of the sand table, planted them in the positions of Xianyang Pass and Xima City, and then continued to say to Song Qing and He Jin, "Here is the 20,000 yuan army, the classification of the troops, I have already said it just now." You also know the speed of the cavalry's march, it only takes three hours to reach Pingyang Pass from Xianyang Pass, and his infantry except for the Wolf Knight Legion, it takes at least a day to reach Pingyang Pass. Therefore, the five thousand cavalry should arrive at Pingyang Pass in one day plus three hours, while the wolf knights should arrive at Pingyang Pass after six hours a day, and the time when the other troops arrive at Pingyang Pass should be the next day. ”

The terrain from Xianyang Pass to Pingyang Pass is almost all plains, which is very suitable for cavalry attacks, and 5,000 cavalry can give full play to their greatest advantages at this time. However, after all, cavalry is an assault class and is not suitable for siege warfare, and the wolf knight belongs to the elite infantry, so if Qian Yuan targets Pingyang Pass, he should wait until the wolf knight arrives at Pingyang Pass before launching a siege battle.

"The method we used before will definitely not be able to be used anymore, we are too different in terms of strength, but the cavalry and wolf knights are not good at forest warfare, so this is our ambush location."

When Li Gengyun spoke, he planted a military flag on a mountain ridge thirty miles away from Pingyang Pass, it should be said that this mountain range is different from other places, it is the only way from Xianyang Pass to Pingyang Pass, and the road through it passes through the middle of the mountain, which is equivalent to a U-shaped valley.

"The opening in the valley is not big, only two people can pass in parallel, if it is cavalry, they can only pass in turn, seal the tail of the valley, and then after they enter the valley, seal the opening again, and throw some lighted firewood from the top of the mountain, I think this fire can at least let thousands of cavalry fall inside."

"You mean Valley Between the Teeth?" Song Qing looked at the position of Li Gengyun's flag, touched his chin and nodded, he also agreed with the other party's statement in his heart, and then pointed to the entrance of the valley and said, "Do you want to wait until all the cavalry enters before sealing the entrance?" ”

"That's right, there is not a lot of space in the valley, if they know that the road ahead is blocked, they can turn around in the middle, the slopes on both sides are steep and difficult to climb, then when they concentrate on making a U-turn, it is the best time for us to ambush." Li Gengyun pointed to the terrain of the valley and continued, "However, we have limited numbers, and the preparation time is only one day, so this time their losses will not exceed about a quarter of the entire team, and when they rush out of the valley, they should still have three to four thousand cavalry left." ”

"After escaping the valley, they will do two things, one is to go up the mountain to destroy our soldiers, and the other is to hurry to find water."

"That's right, the fire is burning in the valley, and the smoke is thick, it will definitely make them feel very uncomfortable, and a dry mouth is inevitable, and the nearest water source is here!" Song Qing understood Li Gengyun's tactics, he nodded, and then pointed to a waterhole not far from the Valley of the Teeth and continued, "Qinghuatan is on the road from the Valley of the Teeth to Pingyang Pass, and the water source here flows from the branch of Luoshui. ”

"It's already after the autumn equinox, and the water level of Luoshui has dropped a lot, and the water level of the West Falling Water will naturally not be high, so as long as the West Falling Water is intercepted halfway and then led to other places, then Qinghuatan will become a backwater."

Li Gengyun had a wicked smile on his face, looked at Song Qing and He Jin and said, "What should I do next, I don't need to say more!" ”
