Hearing Guo Zhao's answer, Dian Wei and Xu Chu looked confused.
Since Yang Ling was not in the camp or with Cao Cao, where would he go?
Just when the two of them were at a loss as to where to look for Yang Ling, they heard the sound of horse hooves coming from outside.
Dian Wei and Xu Chu hurried out of the camp and saw that it was Yang Ling returning from beating the horse.
Behind him were Zhou Cang and Zhang He.
Dianwei was immediately overjoyed and said quickly,
"Brother, you are back. Where have you been? Let us find it easy!"
"I'm going to find a way to break the city."
Yang Ling smiled and jumped off the horse.
"What a coincidence, the Prime Minister just asked us to invite you to come over and make suggestions."
"Okay, let's go there now."
"good!"
Dian Wei nodded to Xu Chu and walked towards the Chinese army camp with Yang Ling.
Chinese army camp.
After finishing discussing the military affairs with everyone, Cao Cao looked at the sand table on his desk while eating some white rice, his brows almost twisted into the Chinese character "Sichuan".
Only by conquering Yecheng and taking over the north can Liuhe be conquered and the world unified.
If you cannot capture Yecheng in one day, you will not be able to achieve this wish in one day, and there will be great risks!
Thinking of this, Cao Cao put down the white rice in his hand and sighed.
"Haha, why did the Prime Minister sigh for no reason?"
Yang Ling walked in with a smile.
"Ziyi is back!"
Cao Cao quickly stood up and complained with a somewhat reproachful tone,
"Where have you been? I'm looking for your advice."
Yang Ling smiled calmly and said,
"I went to find a way to conquer Yecheng for the Prime Minister!"
"real?!"
Cao Cao was surprised and happy when he heard this.
"Have you come up with any ideas?"
Yang Ling did not answer directly, but walked to the sand table.
On the carefully made sand table, there are mountains, rivers, passes and cities, and the terrain of Jizhou is clearly presented in front of everyone.
"Ye City is extremely plentiful in terms of food and grass, soldiers and personnel."
"There are only two ways to go without paying a huge price."
"The first is to besiege but not attack. When the food and grass in the city are exhausted, Yuan Shang will naturally fail without attacking."
Yang Ling talked eloquently,
"But the Prime Minister will definitely not be able to use this method."
Cao Cao nodded.
Yecheng is the hometown of the Yuan family, and the food and grass stored up may only last ten years.
Is it possible that they will besiege Yecheng for another ten years?
Let alone ten years, even if the siege lasted for one year, Cao Cao still couldn't accept it.
After all, there are still Yuan Tan, Liu Biao, Sun Quan, Liu Bei and others watching.
As long as Cao Cao shows a slight flaw, they will swarm him!
"What's the second way?"
Cao Cao asked.
Yang Ling spit out two words:
"Water attack!"
Cao Cao was startled and subconsciously looked at the sand table.
Where Yecheng is located on the sand table, there is only one Huan River nearby.
"With the water flow of Huan River, it would be difficult to attack Yecheng with water, right?"
Cao Cao said doubtfully.
It was not that he had not considered water attack before, but in the end he gave up the idea because of insufficient water in Huan River.
"Yes, there are indeed some problems right now."
Yang Ling confidently nodded to Zhang He who was standing aside.
"But I just took General Junyi for an on-site inspection. According to what he said, Hebei is about to enter the peak flood season!"
"The Prime Minister can order people to build dams in advance and block the water inlets everywhere!"
Cao Cao was so happy that he almost burst into laughter!
"As expected of Ziyi, he came up with a plan to destroy the city so quickly!"
"Oh, I suspected you were slacking off earlier, but I didn't expect you were going on a field trip. I really wronged you!"
Cao Cao said with a look of remorse.
"It's my fault for not saying hello to the Prime Minister in advance."
Yang Ling paused, then smiled and said,
"In addition to the Huan River, we can also dig another waterway to divert water from the Yellow River!"
The Yellow River watercourse seen in later generations was actually formed after many changes in its course.
The current Yellow River waterway has a branch passing not far from Huan River.
As long as an army is sent out, it will take at most a month to connect the Huanshui River with the branch of the Yellow River.
"In this case, no matter how strong Ye City is, it will definitely be broken by the Prime Minister!"
Yang Ling smiled.
"Okay! Ziyi is really smart!"
Cao Cao couldn't help but praise loudly.
The problems that troubled Cao Ying and others were solved by Yang Ling in an understatement!
Dian Wei, Xu Chu and others on the side looked at Yang Ling with admiration!
"Dian Wei, Xu Chu, you two quickly go and tell the engineering camp to follow Zi Yi's instructions and prepare to store water!"
After Cao Cao finished giving instructions to Dian Wei and Xu Chu, he was in a good mood. He held the rice bowl in his hands again and started eating with big mouthfuls.
When Yang Ling saw this, he couldn't help laughing and said,
"Why does the Prime Minister only eat without vegetables?"
"Zi Yi's strategy is like fine food, what else should I eat?"
Cao Cao joked.
Everyone burst into laughter.
…
Early the next morning, at the gate of Yecheng.
"My son Yuan Shang, the Prime Minister is your godfather. You are an unfilial son. Why don't you quickly open the city gate and let us in?"
"You are so unfilial, aren't you afraid that if Yuan Benchu knows someone secretly, you will make him angry to death?"
The lord Zhou Cang followed Yang Ling's instructions and rode out of the range of the bow and arrow, shouting curses at the top of his lungs.
Listening to his yelling and cursing, Ma Yan, the military general on the top of the city, curled his lips and said to the soldiers on the side,
"If Cao Jun does not attack the city, he must not take any action!"
"Here!"
Ma Yan glanced at Zhou Cang, then swaggered down the city wall and walked towards the Yuan Mansion in the city.
In the court hall of Yuan Mansion, Yuan Shang was discussing political affairs with Shen Pei, Feng Ji and other staff.
"Greetings, my lord!"
After Ma Yan walked in, he bowed respectfully to Yuan Shang.
"General Commander-in-Chief, there is no need to be polite!"
Yuan Shang waved his hand and said with concern,
"What are the movements of Cao's army outside the city?"
"Reporting to my lord, Cao's army did not attack the city today. They only sent one man to yell and curse outside the city. The curse was very unpleasant."
Ma Yan said honestly
Although they didn't hear it with their own ears, everyone could probably imagine it.
However, Yuan Shang was not angry. Instead, he laughed and said to Feng Ji and Shen Pei,
"Everyone, Cao Cao must have had no choice but to act like this!"
"Yes, it seems that yesterday's siege caused Cao's army to suffer heavy losses."
Fengji twirled his beard and said with a smile,
"Cao Cao should understand now that Yecheng is not so easy to win!"
"It's just a pity that my cousin died in the battle in Zhi County, otherwise he would have sent another army to attack Cao Cao, and he would have won a complete victory!"
Yuan Shang couldn't help but sigh.
But at this moment, Shen Pei on the side was a little suspicious and said,
"My lord, Mr. Yuan Tu, why do I feel that something is not right?"
