At this time, Cao Cao was still busy with the confrontation with the Yuan family.

"Now the Yuan family is in chaos, Yuan Shang, Yuan Tan, and Yuan Xi are already fighting in the Crazy Palace, if the lord doesn't do something now, he will miss this great opportunity!" Guo Jia was the first to express his opinion.

Cao Cao touched his beard and said leisurely:

"Indeed, now is the best chance to pacify the North, but the problem of troops ......"

"Don't worry about this!"

Jia Xu stood up, glanced at Guo Jia and said:

"You have a god general Cao Shuo, since he can pacify the Huns, then a few wastes of the Yuan family can't be ranked at all!"

"Yes!"

Cao Cao thought about it, and laughed: "My Qilin'er will definitely give him a holiday after fighting this time, and now I will send someone to find him!"

"Yes!"

The herald turned around and ran, and at this time, the strategists and generals also happily began to discuss:

"This is a great opportunity to pacify the great cause of the north!"

"Indeed, thanks to the god man of Cao Shuo Gongzi!"

"It's the last battle."

……

Cao Cao listened to these words, and his heart was also very happy.

These words are all about patting their own asses on the side, which is a comfortable batch!

"Lord, son, he ......"

And at this moment, the herald returned, with an expression that wanted to say nothing and stopped.

"What's wrong with him?"

Cao Cao once again had an ominous premonition in his heart.

"Childe said he didn't have time now, he wanted to run a school and a magazine, let you run them yourself."

The herald swallowed and continued:

"Childe also said that if you can't even kill the three brothers of the Yuan family, you won't have a father like you......"

"Poof!"

Many of the strategists present couldn't hold back and laughed out loud.

"This shaft!"

Cao Cao trembled with anger and threw a punch at the table.

At this time, Cao Shuo was still studying the knowledge of metallurgical technology.

The reason why he didn't want to go to the Yuan family with Cao Cao to clean up the portal was mainly because Cao Shuo knew very well in his heart that with Cao Cao's strength, it was too simple to dispose of the three brothers of the Yuan family.

Moreover, in addition to schools and metallurgy, Cao Shuo still has to continue to promote corn, potatoes, and sweet potatoes, which are fresh crops that people have never seen during the Three Kingdoms period.

Cao Cao also had to continue to recharge his batteries and study the knowledge of chemistry upward.

These made Cao Shuo dream back to the third year of high school, and he was not even interested in playing with his wife at night.

In addition, Cao Shuo came back from the Xiongnu this time and brought a good thing.

Cotton.

Now the people here in Cao Cao wear clothes that are either made of silk or linen.

And cotton, a crop, is perfect for both cold and comfort.

Cotton clothing is so important for improving people's living standards.

Simply from the aspect of cold protection, cotton can greatly improve people's life happiness.

Nowadays, people use leather clothes for the rich, while those who don't have money fill them with catkins or reeds, and wear a few more clothes to resist the cold.

Before Cao Shuo arrived, many people froze to death in the cold winter every year.

Now Cao Shuo's main goal is actually to conquer the world, but for now he still has to solve people's life problems.

In fact, Cao Shuo had also thought about this problem before, but he had never found cotton seeds in the store, but he found it this time when he went to crusade against the Huns, which was also a huge harvest.

In addition, there is wool.

"Now the Xiongnu are also Han, you can raise more cattle and sheep, although the transportation is inconvenient, but at least it can ensure the supply of meat in some areas."

Cao Shuo thought silently in his heart.

Now the territory of the Xiongnu is already the grazing land of the Han Dynasty!

"There is also milk, although it can't be transported, but it can be made into milk flakes, dried milk, it's almost the same!" The more Cao Shuo thought about it, the more happy he was in his heart.

And now Cao Cao is thinking about the Northern Expedition to find the three brothers of the Yuan family.

Although Cao Shuo was really too lazy to go over this time, he still gave Cao Cao a good thing.

This is the military rations, compressed biscuits.

You know, the role of grain and grass in war is too great.

In a long-term battle, whoever has more grain and grass reserves will have a greater chance of winning.

In addition, Cao Shuo has also been improving the magic of compressed biscuits.

After continuous experimentation, Cao Shuo's compressed biscuits can be produced on a small scale.

So, before Cao Cao set off, Cao Shuo directly entrusted Guo Jia to give this thing to Cao Cao.

"Lord, this is a sample of Xinshi military rations that Gongzi asked me to send, this thing is easy to carry, such a small piece is a meal!"

Guo Jia took the biscuit and began to introduce it to Cao Cao.

"Can this thing be used as a meal?"

Hearing Guo Jia's voice, the strategists and generals all gathered around.

"According to what Cao Shuo Gongzi said, he fought against the Huns, and he usually eats this thing."

Guo Jia glanced at the crowd lightly and said, "This compressed biscuit has also made a great contribution." ”

"This ...... Is it really that amazing? ”

Jia Xu picked up the biscuit and looked at it, with disbelief written on his face.

"You can try it, it's all samples."

Guo Jia said, took out a snakeskin bag of compressed biscuits and distributed them to the strategists and generals: "This is cooked food, everyone can eat it directly." ”

"Oh? Is this cooked? ”

Hearing this, everyone became more and more curious, holding a biscuit and stuffing it in their mouths like chickens.

"This ...... Like a stone! ”

Everyone complained, but after eating a whole piece, they also found that the compressed biscuits were not very difficult to eat.

On the contrary, it is sweet and has nuts in it.

Better than the main food!

And this is the Three Kingdoms period, and the things eaten outside are even more outrageous, all of which are air-dried steamed buns, thin rice porridge and the like.

The generals ate the compressed biscuits, and they all wanted to snatch the snakeskin bag in Guo Jia's hand.

"In addition to eating dry, this can also be boiled in water."

As he spoke, Guo Jia continued to show it.

Break the compressed biscuits and throw them into a pot of boiling water, and they will turn into a pot of paste in a short time.

"This ...... It's okay to look at it. ”

Yu Ban looked at this thing with a grin.

Try to imagine that you can eat this thing on the battlefield, it is really a fairy meal.

And the volume of this compressed biscuit is still very small, not to mention easy to carry, but also to resist hunger.

No matter how you look at it, this is an artifact.

"Lord, this thing is simply an artifact invented by Cao Shuo's son!"

Jia Xu couldn't help but sigh at this time.

"A good thing indeed."

Cao Cao looked at the happy appearance of the strategist general, and he couldn't help laughing in his heart.

Sure enough, it's a unicorn, who can invent this divine thing.

Anyway, it's really stable when it's going to war!
