Ma Yunlu was very familiar with Zhang Fei. After all, General Zhang San came to visit from time to time, and occasionally even brought his family to have a meal.

She secretly scolded this black guy for talking too much. You and your brother exchange letters and talk about your affairs. What do I do?

Guo Jia said seriously: "Is Mr. Guo one of those wild and rebellious people who doesn't respect etiquette and law?"

When Guan Yu heard this, his eyes suddenly became intriguing. Who is Guo Jia? He will not forget where they first met.

It was okay that he didn't speak, but his words seemed to be trying to cover up. Who didn't know that Guo Fengxiao was a dissolute man and regarded Confucian etiquette as nothing?

Ma Yunlu pinched him hard secretly. This man clearly meant to embarrass her in front of outsiders.

Guo Jia felt pain and hurriedly changed the subject and said with a straight face: "Yun Chang, as a general of the army, you have a heavy responsibility. You don't think about how to defeat the enemy, but instead care about other people's family affairs. Do you deserve the Prime Minister's trust?"

Guan Yu was stunned, then his face turned redder than Guan Gong, gritted his teeth and said: "The military advisor has taught you a lesson, Guan has learned a lesson."

Then the two got down to business.

Guan Yu asked: "May I ask the military advisor, do you want to use that new weapon?"

Guo Jia shook his head, "The trump card is the trump card because it has not been revealed yet. If we expose all our methods from the beginning, the subsequent battle will become very difficult to fight!"

"The only option is to attack by force!"

"We can order people to cross the city and show intention to surround Cao Ren. If he does nothing, we will use gunpowder to break the city."

"What if he breaks through?"

"Then we will get the whole city for free."

"good!"

A smile appeared on Guan Yu's face. He had understood Guo Jia's intention, which was to use a secret weapon as a basis to force Cao Ren and Xun You to make a choice.

However, he randomly thought of something: "Our army only has 80,000 troops, which may not be enough to trap Cao Ren."

"Who said we only have 80,000?"

"Could it be."

"Xun Yu has sent 50,000 troops from Chang'an. It is estimated that they will arrive in the next two days."

Guan Yu's heart moved, "New army?"

As far as he knew, in addition to the troops guarding various passes, the rest of the elite soldiers were taken by his eldest brother to attack Yizhou.

In other words, this army has just been recruited.

"It's just a new army to cooperate with the encirclement. And this army is not entirely a new army. There are also many veterans in it, and they still have some fighting ability."

This is the method of using the old to lead the new, which can allow the new army to quickly form combat effectiveness.

Guan Yu nodded, and then said with emotion: "No wonder the military counselors said that Xun Yu was the eldest brother of Xiao He. He is indeed good at staying at the rear."

Whether it was the dispatching of troops and horses, or the escorting of grain and fodder, Xun Yu did everything in an orderly manner, and Guan Yu had a little more respect for him.

Although he is arrogant, he highly recognizes those who have real talents and learning.

"Wen Ruo's talent is not just about governing." Guo Jia shook his head and laughed.

Xun Yu was an all-rounder and could hold any position. He even suspected that if Liu Bei needed it, Xun Yu could wear armor and go into battle and become a Confucian general like Chen Qingzhi.

"According to the reports from the scouts sent by this general, Guan Yu divided his more than 100,000 soldiers and horses into multiple groups and set up camps at the four city gates. It is likely to surround us."

A few days later, Cao Ren learned about Guan Yu and Guo Jia's arrangements, and immediately became restless.

What he worried about was not that he would run out of ammunition and food after being besieged, but that he would be unable to fly after being breached.

When Xun You heard this, he could only lament that his clan uncle was so powerful that when Liu Bei led the main force in Guanzhong to attack Jizhou, he could still muster tens of thousands of troops to support Guo Jia.

Xun You was originally worried about Guo Jia's conspiracy, but now it seems that he doesn't need to. The other party can completely suppress them with great force.

Cao Ren also had the same idea: "Although Liu Bei owns three states, Liangzhou and Bingzhou do not produce much food after all. How on earth can he afford to support so many troops?"

Counting the troops in Yizhou and Liu Bei's troops stationed in various places, his total military strength is close to more than 400,000, right?

How does he afford it?

Cao Ren didn't understand.

Cao Cao is also a land of three states, but his total military strength is not even 300,000.

Xun You replied: "General, please take a look at these two things."

Only then did Cao Ren notice that Xun You had been carrying a package in his hand, but he was too preoccupied to notice it.

"This is."

One of them he recognized, which was rice. However, he did not recognize the things that were stained with soil and looked like stones.

Naturally, Cao Ren would not think that Xun You would joke with him with a stone when he had nothing to do.

"The name of this thing is potato. According to our military spies, the yield is extremely high. Also, although this thing looks the same as the rice we usually see, the yield is completely different."

"Liu Bei has been planting these things on a large scale in Guanzhong for a long time, but they have kept it extremely secret and no news has leaked out."

"Now he seems to have relaxed his policies and allowed these things to flow into the market. Does the general know why this is?"

Xun You said with a solemn expression.

Cao Ren was silent when he heard this. If these things were as Xun Yu said, then he could probably guess the inside story.

He used to hide them because Liu Bei didn't want other princes to know about these two treasures. As for why he let them go now, maybe it's because of his self-confidence.

Liu Bei felt that he was about to dominate the world. At that time, the whole world was not the king's territory, and the people who led the land were not the king's ministers. Is it necessary to help his own people?

"Because Liu Bei has regarded the world as his own." Cao Ren sneered. Liu Bei's confidence was equal to his contempt for them.

"Yes."

Xun You heard Cao Ren's mood and asked again: "Do you know the specific yield per mu of this thing?"

"How many?"

Xun You compared the numbers, and Cao Ren's expression suddenly changed.

"Impossible, absolutely impossible!"

"I didn't believe it at first, but now I believe it." Xun You shook his head and said, "Why can Guan Yu raise 150,000 troops in a mere Bingzhou? Why does Liu Bei dare to fight on two fronts?"

"Because he has enough food and grass, he can launch successive wars and dominate the world."

Cao Ren took a deep breath and asked, "Do we still have a chance to plant this thing?"

"Maybe, maybe"

Xun You shook his head. He was not sure himself, and Cao Cao must be the same.

In terms of strategy, he is not afraid of Guo Jia, his uncle and others, but in terms of weapons, promiscuous skills, etc., they seem to have been lagging behind.

Cao Ren took the potatoes from Xun You's hand and asked, "Is there any extra of this stuff?"

"Yes, it's not difficult to buy on the market now."

Xun You was a little confused. Cao Ren asked why?

Then he saw Cao Ren pull out his sword, peel off the potato skin, and then gnaw it hard.
