The digger army, the engineer who is responsible for digging fortifications, trench tunnels, etc., is generally responsible for digging tunnels into the depth of the enemy's military camp, so it is called the "digger army".

This is a very common type of army in the Eastern Han Dynasty, which fights with other types of armies. There are also many ways to deal with this kind of soldier, such as pouring water into the tunnel, pouring oil, and using smoke.

However, these are only the responses of the side after digging and poking.

Therefore, when Cao Cao asked about the plan, Guo Jia said: "The lord can dig a trench on the periphery of his own soil mountain, and the excavation of the Qin army is immediately convinced, and digging a trench can also increase the garrison strength of our army." ”

Cao Cao was overjoyed, and immediately mobilized an army of 50,000 to start digging trenches, day and night. In just two days, they dug a foot of ground and surrounded Guandu.

When Xu Shu saw this qiē, he knew that the plan had been leaked, so he stopped the excavation work so as not to waste his troops.

The base camp of the Qin army, the big tent of the Chinese army.

"Cao Cao has Guo Jia as his military advisor, not to be underestimated!" Qin Feng said depressedly.

Xu Shu immediately said: "The lord is righteous and seeks from all directions. Guo Jiazai has the ability, and it is also the ability of the individual. The lord might as well contain Cao Cao's main force here, and when the armies of all walks of life are victorious, he can gather the crowd to strike a thunderous blow. ”

So, Qin Feng followed his words.

At this point, the two sides entered a stage of strategic stalemate.

In the blink of an eye, a month has passed, and August should have been crisp and crisp, but the sun is still shining, and it seems that the drought will not be alleviated until the middle of winter when the snow falls.

Fortunately, Qin Feng used Zheng Hun to repair water conservancy, and there were bumper harvests year after year, and the reserves were sufficient. It won't be a problem until this time next year.

However, at this moment, Cao Cao was already anxious, and he couldn't hold on anymore. for his bread and grass will be gone.

At this time, a piece of news became the last straw that crushed Cao Cao's psychological defense.

Qin Li Jian'an seven years. In August 198 A.D., the Qin army conquered the north general Zhang He led the governor Lejin and the strategist Tian Feng, commanded an army of 100,000, although the loss of 20,000 soldiers, but swept Jibei, Taishan, Dongping County, and began to besiege Puyang, the seat of the East County.

And Zhang Liao, the general of Qin Feng's expedition to the east, accompanied by the governor Li Dian, used Jia Xu's strategy. took advantage of the drought to attack Qian County, making Qiao County Jiao County. Although he lost 30,000 soldiers, he wiped out the 70,000 Cao troops entrenched in Qian County.

The Xiahou Department who defended Qian County, led 30,000 remnants of the army, and retreated to Runan.

This was a fatal blow to Cao Cao, even if he could withstand Qin Feng's main force in the middle, he would not be able to save the trend of defeat, unless he could defeat Qin Feng's main force.

Fortunately, the city of Luoyang was tall and withstood the offensive of the Qin army's Xu Huang Division. Coupled with the Tiger Prison Pass, Cao Cao, who had lost one-third of his territory, still had a chance to defend the other two-thirds.

Guandu, Cao Cao's mansion.

At this moment, Cao Cao no longer had the calmness when he repelled Qin Feng, and his heart and gall were broken. Lian shouted: "Fengxiao, what should I do?" Now that the food is running out, the county is lost. It was also a matter of time before Dongjun fell. ”

"It's better to retreat, retreat to Xuchang. In Runan, Xuchang, and Tiger Pass, rearrange the defense line! ”

Guo Jiafen quickly shook the big pu fan. Cao Cao was at a great disadvantage from the beginning, and Qin Feng never showed any flaws, so Guo Jia had no way to do anything.

When there are no flaws on both sides, and there is a considerable amount of wisdom, the side with strength will be able to win the final victory if it is steady and steady, which is the sorrow of the top strategists on the weak side, and the most representative is Zhuge Liang.

Guo Jia blamed himself, but the other party had no flaws, and he was helpless, and said, "Lord, do you want to give up Gunzhou?" ”

Cao Cao was already anxious, and he broke the jar and said: "Qin Feng's Zhang Liaobu has broken through Qian County, and Jiyin and Liang Guo, who are in the middle of the bag, are finished. In fact, only Chenliu County ...... is left in Gunzhou. When he said this, he said dejectedly, "Don't ...... it." ”

"No......." Guo Jia shook his head, "If we retreat, Qin Feng will be able to concentrate more forces and break our army one by one. ”

"What then!" Cao Cao was very annoyed by the current shape, patted the desk, and roared: "Could it be that you stay here and wait to be surrounded by Qin Feng's three-way army!" ”

Guo Jia hurriedly said: "My lord, you can send an envoy to ask Yuan Shu to march to Xuzhou quickly." In this case, Qin Feng would definitely order Zhang Liaobu to meet Yuan Shu. In order to return to Xuzhou before Yuan Shu, Zhang Liaobu would definitely retreat in a hurry. At that time, General Xiahoudun of Runan also had a chance to counterattack, and he only needed to break through Qiaoxian again, and most of Gunzhou would still be in your hands. ”

He said: "General Xiahoudun can merge with Yuan Shu to defeat Zhang Liao, at that time, let Yuan Shu take Xuzhou, Xuzhou is empty, he will definitely be able to succeed lightly." At that time, the greedy Yuan Shu would definitely send troops to Qingzhou again. And Qin Feng will definitely let Zhang He come back to help, and the lord can make General Xiahoudun take the opportunity to intercept it. ”

"The lord only needs to hold on to Guandu, even if he abandons Luoyang, General Xiahou Yuan will be able to surround Qin Feng on three sides when he gets out of the tiger prison. Eliminate Qin Feng, and the north can be pacified with a piece of paper! Guo Jia was very confident in sketching a blueprint for Cao Cao, although he was only fifty percent sure, but his face was ten percent confident.

"Will it really succeed?" Cao Cao's face was cloudy.

Guo Jia said again: "At the very least, Qin Feng retreats, and the lord can unite with Yuan Shu to fight against Qin Feng together!" ”

"Good!" Cao Cao took the case and said, "Send an order to Runan's full favor and ask him to go to Huainan immediately and ask Yuan Shu to send troops." Sue sù Yuan Shu, if he doesn't send troops, after this general is defeated, it will be his turn next! ”

This time, Guo Jia really said very confidently: "Lord, please rest assured, Yuan Shu will definitely send troops." ”

……

Three days later, Huainan Shouchun.

"General Yuan, retire first!" With a bow, he went to the post house to rest with a Huainan official.

As early as last year, Qin Feng and Cao Cao allied to jointly attack Liu Bei. Yuan Shu fished in troubled waters and wanted to sneak attack Xuzhou, but he didn't want to meet Qin Feng and Cao Cao on the road, but he didn't catch it, and was finally defeated by the Qin and Cao coalition forces, and lost tens of thousands of horses and fled back to his lair in a hurry.

However, the general trend of the world is to fight and make peace, and after Qin Feng got Qingxu Erzhou, his strength skyrocketed. Xuzhou borders Huainan in Yuanshu. In order to survive, Yuan Shu formed an alliance with Cao Cao in order to survive. Fight against Qin Feng together.

In the council chamber, only his own people remained. Yuan Shu then said: "Ladies and gentlemen, Cao Cao asked General Ben to send troops to Xuzhou and besiege Wei to rescue Zhao, what do you think?" ”

The strategist Yan Xiang said, "My lord, this is a heaven-sent opportunity. Now Qin Zijin's four-way army is attacking Cao Cao, and the rear is empty, so he can take the opportunity to achieve the hegemony of Qingxu and Xuzhou! The lord should send troops immediately, don't miss the opportunity! ”

"No!" Strategist Yang Hong retorted and said, "How can Xuzhou be without a garrison. If Qin Zijin's army is broken, it will inevitably cut off my way back. It is better to send troops to Yuzhou and attack Xuchang ....... ”

"Does Yang Hong want to trap the lord and injustice?" I heard Yuan Yin say: "If everyone knows that the lord and Cao Cao are allies today, how can they do something that distrusts the world." Besides, even if we can get Xuchang, but at that time, Cao Cao was defeated, what can we use to resist Qin Feng's army? ”

Since ancient times, the weak have united against the strong, and if the weak attack each other, they will inevitably be destroyed by the strong.

Yuan Shu made the right decision. was sent to Xuzhou, and he immediately appointed Ji Ling as the general, Chen Lan as the governor, and Qiao Rui and Lei Bo as the vanguard. Yan Xiang was engaged in the army, raised 150,000 soldiers, and went to Xuzhou.

Yuan Jun outside Shouchun was transferred. The intelligence guard immediately got the news, and the flying pigeon passed the book to Qin Fengjun.

The Qin army battalion. The Great Tent of the Chinese Army.

Qin Feng's face was solemn and said, "Two military advisors." Now Yuan Shu has really raised troops. ”

Xu Shu immediately said: "Lord, this matter has long been expected, and the lord can send an envoy to Jiangdong according to the plan in advance." ”

Xun Yu said: "The lord had grace and Jiangdong Sun Ce back then, and he had a gap with Yuan Shu, this opportunity is rare, Sun Ce will definitely send troops to Huainan." As expected, when Sun Ce raised his army, Yuan Highway would definitely retreat to defend his foundation. ”

So, Qin Feng Feige sent a message to Jiangdong Intelligence Guard, and the war pigeon flew extremely fast, so on the second day of Yuan Shu's army, the envoy of the Intelligence Guard entered Sun Ce.

As expected, Sun Ce was a righteous person, firstly, to repay Qin Feng's kindness for giving grain, and secondly, to come to the Central Plains War, in the chaotic situation at this moment, it was also a good opportunity for him to seize Huainan. So he immediately agreed to send troops and formed an alliance with Qin Feng in this regard.

When the news came that Sun Ce had raised troops to kill Huainan, Yuan Shu was full of courage and did not expand his territory, so he hurriedly returned to Huainan with a large army and began to defend and counterattack Jiangdong's soldiers and horses.

And Xiahou Dun's troops have already sent troops, intending to take the opportunity to recapture Qian County when Qin Feng's Zhang Liao Department withdraws his troops. Now he had no choice but to return to Runan and continue to strengthen the garrison of Runan.

Under the troubled times, the various forces restrained each other, so Qin Feng effortlessly retreated Yuan Shu's army of more than 100,000.

On the side of the Qin army, the big tent of the Chinese army.

Qin Feng said with a smile: "Cao Cao's allies are gone, and he doesn't have much food and grass...... ”

The Central Plains is about to fall, and it sits on the land of eight states, so the hegemony can be achieved. The famous ministers and good generals under his command, unless they are teased by the hot brain, it is more difficult to defeat the foundation than to ascend to the sky. And Qin Feng, who came in the later generations, how could he do something that ruined the foundation.

Therefore, the current Qin Feng's agitation in his heart cannot be expressed in words. Because the world, the throne, is not far from him. How can you not be excited about this in the future when you can't even dream of it.

However, Qin Feng secretly warned himself that although the general trend had been achieved, he still needed to be cautious to avoid the overturning of the boat in the gutter. He pondered about it......

At this time, the military advisor Xu Shu said: "Lord, Yuan Shu has withdrawn, and Cao Cao has lost the opportunity to fight back. There was a shortage of food in his army, and he thought that he would soon retreat to Xuchang and use the strength of the city to confront our army for a long time. ”

Xun You said at this time: "Such a thing should be avoided and find a way to eliminate Cao Cao's main force in Guandu, so as not to form a long-term war." If it is delayed for a long time, the internal friction of the Central Plains will be great, and it is very likely to form a ...... of change. ”

Yongliang's Lu Bu, Jingzhou's Liu Biao, Huainan Yuan Shu, Jiangdong Sun Ce, these are all variables. Therefore, it is necessary to do everything possible to defeat Cao Cao and deter the princes from all walks of life. lest these jackals spy on the fat of the Central Plains.

Qin Feng, who was pondering, said to himself: "After many years of waiting, the time has come, and now it has finally come in handy." ”

Xu Shu and Xun Yu looked at each other, not knowing what the lord meant.

At this time, Qin Feng suddenly smiled and said, "Yuan Zhi, I don't know which general in the army likes to drink?" (To be continued......)
