Three Kingdoms: Shocked, my father-in-law is Cao Cao!

No matter how you look at it, it is impossible to attack in three to five days.

However, he didn't have any hope in the first place. He came here to ask for a prescription to cure foot odor. Could it be that he still expected a young boy to help them break through Xiapi?

"Young master, please give me a cure for my stinky feet."

"Here, spray it every day after washing your feet."

Jiang Zhe reached into his sleeve, took out a bottle of athlete's foot spray from the system space, and said angrily, "Old Xu, look at your expression, do you believe me?"

"The young master said, Cao Jun surrounded Xiapi City and couldn't attack it for a long time. Why did he suddenly manage to take it down in three to five days?"

"Isn't that easy?"

Jiang Zhe rolled Xu Chu's eyes, and said, "Let me ask you, what is Lu Bu's biggest support for defending Xiapi City?"

"Lu Bu?"

Xu Chu looked puzzled.

Although he didn't want to mention this name, he had to admit that in terms of personal combat power alone, Lu Bu was indeed unparalleled in bravery and invincible in the world.

"Lü Bu, if you are brave but not resourceful, you have nothing to fear."

Jiang Zhe chuckled and shook his head.

"Fifty thousand Xiliang defenders?"

Xu Zhu was even more curious.

"The Xiliang army is indeed brave in cavalry, but they are not good at defending the city."

Jiang Zhe shook his head again.

After thinking for a long time, Xu Chu suddenly realized: "Oh, it's the Sishui River!"

Xiapi City is surrounded by Surabaya on three sides, and the fast-moving Surabaya serves as a moat to block the front. The siege soldiers just moved the ladders over, and they had to pay heavy casualties.

Otherwise, they have been besieging the city for more than a month and have attacked the city several times, why did they fail every time?
"That's right, it's the Sishui River!"

Jiang Zhe took a sip of the fine wine and continued: "Do you know that if Cao Jun uses the Sishui River to attack the city, within a few days, Lu Bu can obediently surrender."

"Are you kidding? That river is used to defend the city. How can it be used to attack the city?"

Without thinking, Xu Chu blurted out.

"Why not?"

Jiang Zhe smiled lightly and said, "Those who win here will be destroyed here. The defense of the city can benefit from the Sishui River, and the city can be destroyed by the Sishui River if you attack the city."

"If you think about it again, during the dry season, the Sishui River is so turbulent that it is difficult for the siege soldiers to wade across the river."

"If heavy rains come again for a few days, the water will inevitably be fierce. At that time, Cao Jun will dig the embankment and flood the city of Xiapi. Is Lu Bu a turtle in the water, and will Xiapi be destroyed without attack?"

Xu Chu thought about it carefully, and his eyes suddenly brightened.

This young man is a bit of a monster!

None of the counselors under the lord's tent seemed to think about the problem in this way, just like he used his stinky socks to wake the lord up.

Fantastic ideas, powerful and unconstrained style, people are surprised!

Xu Chu thought carefully, this plan is absolutely feasible!
Moreover, he dared to say that Lu Bu would never have imagined that the moat that protected him would actually be attacked by someone who would attack the city instead.

After pondering for a while, Xu Chu thought of another crucial question.

"My lord, your plan is indeed very clever, but the premise is that there will be a heavy rainstorm."

Thinking of Jiang Zhe's saying that after three to five days, Cao Jun will win, Xu Chu's eyes lit up and he said, "Could it be that the young master thinks that there will be a heavy rain in the next few days?"

"What in the last few days, I told you that there will be a sudden rainstorm this afternoon, and it will last for three days. Go home quickly and tell your master to pay attention to flood prevention."

Jiang Zhe showed a swearing expression.

"Come this afternoon for three days?"

Xu Zhu trembled all over.

If what Jiang Zhe said is true, this is a once-in-a-lifetime opportunity.

Looking at the sky, he couldn't help smacking his lips, and asked, "Young Master, you see that the sun is shining brightly now, and there are no clouds in the sky, how can there be a sudden heavy rain later?"

At this time, Cai Yan, who brought some more pots of wine, said in a bad mood: "My son knows astronomy first, geography second, and knows how to observe the sky at night. If there is a rainstorm, it will definitely rain."

"Why, you still don't believe it?"

Cai Yan was the first one who dared to question her son.

Know how to watch the sky at night?

That's a one-in-a-million genius!

Xu Chu's eyes were piercing, and he couldn't help asking: "My lord, do you really understand the art of astrology?"

"You understand it when you say it."

Jiang Zhe was noncommittal.

Naturally, it is impossible for him to say that he is a time traveler, bound to a salted fish system, this is what the system told him.

"Young Master's talent, Lao Xu admires him."

Xu Chu stood up unsteadily, clasped his fists and said, "Come again to have a drink with the young master sometime later. Old Xu has something to do later, so he has to go back and say goodbye first."

"Old Xu, can you walk?"

"fine."

Xu Zhu raised his hand, waved it, and staggered out of the courtyard.

It wasn't until the afternoon that Xu Chufang slowly returned to Xuzhou City, and then walked into Cao Jun's tent with one foot here and another.

At this time, in the big tent.

Several of Cao Cao's advisers are arguing fiercely.

"For this expedition, the lord has mobilized all the elite, and Xuchang is almost an empty city. According to reports from sentry cavalry, Yuan Shao's hundreds of thousands of troops have already stationed in Guandu, looking down on Xuchang."

"If Yuan Shao ordered tens of thousands of suspected soldiers to come to help Lu Bu and contain us from the front, but he himself led the army to attack our rear, then Xuchang would be in danger."

"Once Xuchang loses, we will lose nothing and lose ground..."

Xiapi City has been unable to attack for a long time, and now Yuan Shao is eyeing it. Cheng Yu suggested to seek stability and withdraw the army immediately.

"Yuan Shao is a resourceful and indecisive person. He becomes fearful and withdraws to be greedy for profit. When facing the enemy, he is five percent sure that he will not fight, and seventy percent sure that he will not fight. Only when he is very sure can he dare to fight with all his strength."

"How can there be any certainty in this world?"

"If my lord takes down Xiapi City within ten days, Yuan Shao will definitely not dare to act rashly!"

"The most important thing is that if the lord does not eliminate Lu Bu now, when the lord and Yuan Shao show off in the future, Lu Bu will definitely attack Xuchang, and the danger in the future will be greater than the danger today."

"If you want to defeat Yuan Shao in the future, you must first completely wipe out Lu Bu."

Xun Yu advocated that Xiapi must be broken to completely eliminate the serious trouble for the future.

"Cheng Yu has strategy, and Xun Yu has courage. I have learned a lot from both of them."

"Withdraw or attack, Feng Xiao (Guo Jia's word), what do you think?"

Cao Cao didn't change his face, he just smiled, but he was helpless in his heart.

"Using troops means using risks. Without risks, there is no victory."

"Whether it's withdrawing or attacking, the key now is whether we can conquer Xiapi City within ten days as Wen Ruo (Xun Yu's word) said."

"If Xiapi City can be captured within ten days, it will indeed be of great benefit to the Lord's future career as Wen Ruo said."

"But within ten days, if we can't take it, as Zhong De (Cheng Yu's words) said, we will be in danger of eternal doom."

Guo Jia is not guilty of both sides, and is ambiguous.

Cheng Yu asked loudly: "We have been besieging Xiapi for more than a month. We have attacked Xiapi several times and suffered heavy casualties, but Xiapi city is intact. May I ask who can capture Xiapi city within ten days?"
