Fangcheng under the cover of night also fell silent, and the Han Qianjun assembled in the area of Fangcheng rested in addition to the guards and night guards.

When Yu Zhong came, Guan Yu was studying the sand table, staring at the location of Yaoshan Mountain, there is Jiuli Mountain in the west of the main vein of Yaoshan Mountain, Jiuli Mountain and Taizi Mountain in the west face each other, and there is a river valley formed by river erosion in the middle.

This is where the Great Wall of the ancient Chu Kingdom is located, and the ancient pass here is called Yunyang Pass, also called Chu Yu Pass.

The depressed are lush and lush, and have the meaning of lush and strong.

No matter how small the pass is, it is also a pass, and it is necessary to build it.

The river that runs through Yunyang Pass flows eastward and becomes one of the sources of the tributaries of Lishui.

This means that by quickly opening up Yunyang Pass and Luyang Pass, the Han army will be able to appear between Yexian and Luyang, and Zhang Liao will be caught off guard.

Yunyang Pass is not an isolated pass, and Luyang Pass, Shuyang Pass together are called Sanguan, and the road connecting Sanguan is called Guya Road.

There are many passes on this road, and naturally there are many villages named after passes, and legend has it that this is also the place where the Spring and Autumn Feather Country is located.

The largest iron-smelting base in Nanyang is in Yunyang Pass, although it has been abandoned, but the high-quality iron ore will not be abandoned.

However, such a place must be garrisoned by the elite of the Wei army, and it is by no means easy to capture and break through.

Even if it falls, this army that breaks through behind Zhang Liao will be attacked by Zhang Liao and Cao Hong.

In terms of mountain road conditions, if the defenders are prepared, there are too many hidden dangers in the mountain road march.

Unless the defenders can penetrate the defensive line at an unpredictable rate, quickly intersperse before the defenders make targeted arrangements, dividing and disrupting the defenders.

Who in the Han camp can do all this? Tian Xin can, if it is Tian Xin, then the Wei army will have a targeted arrangement, but it is possible to trap Tian Xin in the mountains.

Once it enters the autumn rainy period, in terms of the terrifying rainfall of Funiu Mountain, even if Tian Xin's army can retreat, it will be difficult to use it again.

Therefore, Tian Xin appeared in the area of Yunyang Pass, and the Wei army Cao Xiu and Xiahou Shang could reinforce the Wankou defense line in batches, so that the Wankou defenders could maintain their peak state and block the attack of the Han army in the front.

Therefore, when Tian Xin made a surprise flank attack, it was difficult for the frontal troops to capture and penetrate three times the number of Wankou defenders.

But there is another combination that can achieve the effect of Tian Xin...... Guan Yu thought about it, and put Zhang Fei and Zhao Yun two war games here in Yunyang Pass.

It's a pity that it's too late to mobilize Zhao Yun now, if Zhang Fei and Zhao Yun cooperate with each other as surprise soldiers and suspicious soldiers, they will definitely be able to penetrate Yunyang Pass and appear between Luyang, Yexian, and Kunyang counties.

The frontal battlefield also has Tian Xin's terrifying ability to attack fortifications, so that if he is attacked on his back, he can crush the will of the defenders, so that many of Zhang Liao's preparations will be useless.

In the face of Tian Xin's ability to attack fortifications, the Wei army avoided the field battle, but also divided troops to defend, because it was afraid that the army would gather in one place and be defeated by the fierce offensive led by Tian Xin, and then the whole army gradually collapsed, like an avalanche out of control.

"It's a pity."

Guan Yu sighed lightly, with a faint remorse on his face, he should have listened to Tian Xin, and then persuaded Liu Bei to include Zhao Yun in the Northern Expedition sequence.

Tian Xin can't wait to gather all his forces to fight this battle, as long as he wins, there will be no problems, and he can take care of it calmly.

But Guan Yu has to worry about the overall situation, and Liu Bei has to consider the overall situation...... The Eastern Crusade almost suffered a big loss, and now it also has the idea of guaranteeing the bottom and retaining the force.

With three points of strength left in this way, even if the Northern Expedition fails, there will be no chaos in various places, and they can calmly clean up and wait for new offensive opportunities.

This is not unexpected, Cao Pi guarded the two states with Wu quality, although Cao Hong, who guarded Hebei, was transferred to the front line of the Central Plains to participate in the war, but the Hebei soldiers under Cao Hong's original command were still assembled in Yecheng, and now Cao Hong is the county soldiers assembled in Yanyu and Yuzhou.

The side should also be concerned about the changes in Nanzhong, and should leave the most loyal and reliable elite troops to guard Chengdu, and also leave a tough, loyal, and infallible general to lead and control this army.

I'd rather transfer Zhuge Liang to Nanyang to participate in the war than move Zhao Yun.

Zhao Yun is the security door, you go out to work to earn money, and the property at home must be protected by the security door.

"Princess, Xiahou sent Yu Shifang to see you."

Pei Jun, who was engaged in Zhonglang, happened to be on duty at night, and he reported in front of the barracks, and Guan Yu was meditating on his war games at this time.

The night ban in the army is strict, but it can't be controlled by Tian Xin, nor by his ears, eyes and henchmen.

His thoughts were disrupted, and Guan Yu threw the chess pieces back into the box in frustration: "Enter." ”

Yu Zhong's face was swollen, and when he came in, he took a look left and right, and when he saw that there were few people, he heard Guan Yu smile and ask, "Why is this the world?" ”

"Back to Song Gong, this Zhang Wenyuan also means."

Yu Zhong recounted the scene at that time, and naturally knew the purpose of Zhang Liao sending Wen Qin out to fight with him.

It's not to embarrass Guan Yu, it's just to fight for a breath.

Wen Qin defeated Yu Zhong, who was the peacock Kaiping, and the morale of the Wei army could naturally increase slightly; Although Wen Qin did not win, he also let Yu Zhong, who came in full costume to show off his might, leave, which can be regarded as a blow to the morale of the Han army.

Zhang Liao received the gift, whether he could comprehend the hint or not, whether he would act before the battle, was no longer in Guan Yu's consideration.

Things have been done in place, and the rest of the things are in Zhang Liao's thoughts, depending on how Zhang Liao chooses, no matter how much he thinks about it, it is useless.

As Yu Zhong explained his intention and expounded Tian Xin's original words, this made Guan Yu frown: "Left Army? ”

He was puzzled and went to look at Pei Jun: "Is there a strategy to break the enemy in the military letter sent by the left army recently?" ”

"There are two."

Pei Jun did not pause: "First, send more than 1,000 people to carry banners and arrange flags and banners all over Dongshan to be suspicious soldiers, and second, after the Yamen general Ma Dai led 5,000 cavalry to follow the suspicious soldiers, waiting for an opportunity to attack and capture the enemy's Yuzhou Assassin Shi Lugong's East Battalion. ”

After a slight pause, Pei Jun added: "This is a real plan. ”

Guan Yu nodded slowly, the scope of the battlefield is not large, Ma Dai rode five thousand and arranged it, and he could be used for other purposes at any time, and it would be delayed for about half a day.

Yu Zhong's face was pale, he did not hide his anger, and said in a trembling voice: "Duke Song, our army only knows that Duke Zhao will arrange suspicious soldiers in Dongshan, and Duke Zhao has not informed Ma Dai of the deployment of the first army. ”

Guan Yu's eyelids rose, and his gaze fell on Yu Zhong's eyes: "Really? ”

"Song Gong, there is no joke in the army."

Yu Zhong knelt on one knee and raised his head in response to Guan Yu's scrutiny: "From the Beifu soldiers to the Song Gong's order, from Bowang to the front of the battle, all the official documents of the left army were handled by the lower officials. The lower officials often go in and out with Xiahou, and they are consistent with what Xiahou has seen and heard. ”

Guan Yu clenched his fist with his right hand, stretched his five fingers, and pinched it tightly, and looked sideways at Pei Jun: "Feng first checked the documents of the left army, and sent them to Beifu within seven days." ”

"Yes!"

Pei Jun turned around and went to the compartment on one side to summon the military officials on duty to copy it together, because the manuscript was not afraid of being damaged, and everyone had new paper in front of them.

Guan Yu picked Yu Zhong up, led Yu Zhong to the inner hall for tea, and asked, "What is the mentality of the soldiers in the army now?" ”

"I just complained about the slow progress of the left army and the delay of the fighters, and I was afraid that our army would be harmed by Qiulin."

Yu Zhong carefully considered his words, and carefully replied without leaving a handle: "There are also those who complain about galloping for 200 miles, but there is no battle to fight." ”

"Huh...... Shifang went back to warn Xiaoxian. Let's just say that although the world is heavy, after all, it is the world of the ministers, hundreds of officials, and the people, not His Majesty alone. ”

Guan Yu's face was solemn and there was no smile: "Even if it is a thing of His Majesty alone, it is just an artifact after all, how can it be that Your Majesty is so angry?" ”

Staring at Yu Zhong's unfazed face, Guan Yu affirmed: "Filial piety is the first to look down on the heroes, but there is the worry of the people and the benevolence of the woman." ”

"Your Majesty and a certain also have a proud heart."

"Filial piety should not be taken lightly, compared to the world, filial piety is equivalent to it."

Guan Yu finally raised his right hand and landed in his heart, clenching his fist and hammering lightly: "The world will tell me what I said to Xiaoxian, and let Xiaoxian do what he wants." He must understand that after the Eastern Crusade, His Majesty has come to an understanding. ”

Yu Zhong's tense face stretched, and his eyebrows shone brightly: "Yes, Xiaguan understands." ”
