Hua Tuo didn't know......

The reason why Cao Shuo has so much infamy is because he can brush points!

Every time he saw the slot-like points in the system, Cao Shuo's heart blossomed.

At this time, because of the vigorous publicity of Cao Shuo's magazine, the first recruitment of medical students was still very smooth, and the people who signed up were similar to those who came to study metallurgy at that time.

Many poor families came to Cao Shuo to sign up for the magazine, hoping to use their medical knowledge to make a living in the future.

In this way, Cao Shuo's medical school was in full swing.

But......

The money was also thrown out one by one.

Including the metallurgical class opened by Cao Shuo before, it costs nothing to come here to study.

Moreover, it is also important to eat and live.

That's a huge expense!

But in order to fully popularize knowledge and eliminate illiteracy, Cao Shuo can only do this.

Although many people have learned knowledge from Cao Shuo, there are still some people who feel that reading is useless and would rather stay at home and do nothing.

In this day and age, even if you pay people to come here to study, some people may not come.

In addition, there is the problem of lack of money.

Even if Cao Shuo has basketball, football, glass mirrors, and tolls, it is difficult to recover the money in a short period of time.

Cao Shuo also roughly calculated before, according to the current progress, it is estimated that it will take five years to return to the cost.

"Hey...... Now the winery is almost ready, and now it's really time to watch this wave. ”

Cao Shuo thought silently in his heart.

In this era, there is no such thing as distilled liquor, but Cao Shuo knows that if he really puts this magical liquor into the market, he will definitely be able to detonate it among the people.

And......

Cao Shuo also planned to sell this distilled liquor to southern China on a large scale, so that the people there would be intoxicated with drunken dreams and death.

In this way, it can also corrupt their fighting spirit by the way.

After a few days, Cao Shuo was idle and ready to go to Cao Cao to brush up some experience, and heard Cao Cao discussing the two brothers of the Yuan family.

Now they are all hiding in the Wuhuan area, as long as Cao Cao sends troops, they basically can't resist, they are either exterminated or surrendered.

But this trick also has drawbacks......

Cao Cao was too far away from the Wuhuan area.

However, now Cao Shuo's main road has also been built in Youzhou, and now is the best opportunity to surprise Wuhuan.

"We are sending troops this time, we should put the weather factor first, remember not to underestimate!"

In the discussion of Cao Cao's advisers, everyone attached great importance to the weather in Wuhuan.

After all......

Wuhuan is near the Great Khing'an Mountains, and once it is winter, it is difficult for Cao Jun to resist the weather in that area.

If nothing is done to protect against the cold, the war will be troublesome until winter.

Although it is said......

Cao Cao wouldn't be stupid enough to wait until winter to crusade against the two of them, but these questions had to be thought about before setting off.

What if the war didn't go so smoothly and was dragged into winter by the two brothers of the Yuan family?

In this day and age, how to keep out the cold has always been a big problem.

"Haha, daddy, is this in trouble? I have an idea that can perfectly solve the problem of keeping out the cold! ”

At this moment, Cao Shuo ran to everyone with a smile and said.

"You...... Can it be solved? ”

Hearing this, everyone's faces were full of doubts.

"Cao Shuo, what do you think, is it the oblivion you found in Bingzhou?"

Cao Cao asked Cao Shuo with a confused expression.

"Well, it's just a solution to the indoor heating problem!"

Cao Shuo smiled and continued: "Dad, do you remember that I came back from the Xiongnu and brought back something called cotton? ”

"Huh?"

Hearing the word cotton, Cao Cao began to recall: "Cotton...... That thing doesn't look good at all! ”

After thinking for a while, Cao Cao looked at Cao Shuo vigilantly: "Have you come up with any new tricks to pit Lao Tzu?" ”

Cao Shuo: "......"

He didn't expect that now Cao Cao had been victimized with paranoia.

No wonder, it's really hard to farm points now!

"Ahem...... Daddy, that cotton is not for seeing. ”

Cao Shuo cleared his throat and said to Cao Cao seriously: "The benefits of cotton are in terms of keeping out the cold!" Compared to something like a reed poplar cattrum, I really don't know how many times better! ”

"Huh?"

Hearing that cotton could keep out the cold, Cao Cao's eyes suddenly shot a look of surprise.

"The fruit of the cotton can be picked and filled in the clothes, with this thing, it is enough for the soldiers to move outdoors in the cold Wuhuan!" Cao Shuo said leisurely.

"This ...... Is it true? Cao Cao still didn't believe it.

You know, keeping out the cold is a problem that everyone wants to solve in this era!

Cao Shuo looked at Cao Cao's bewildered appearance and smiled: "Dad, if you still don't believe it now, you can go out with me to have a look!" ”

"Okay!"

Cao Cao didn't say a word, and directly led the strategists to follow Cao Shuo to the cotton field.

Now Cao Shuo has been planting cotton for nearly a year, and the area is also very extensive.

These cottons, in fact, were specially prepared by Cao Shuo for the soldiers, and now they happened to meet Cao Cao's Northern Expedition, and they happened to hit the muzzle of the gun.

The strategists took off their shoes and went to the cotton field to take a look, and they were all overjoyed:

"This thing is really much better than any poplar catkins!"

"Yes, yes, yes, stuffed into the soldier's clothes, the effect of keeping out the cold must be good!"

"It is estimated that it is enough for our Northern Expedition, and there is a kang invented by Cao Shuo Gongzi at night!"

……

Cao Shuo only smiled slightly when he saw this scene, turned back to Cao Cao and said, "How is it, Dad, I, Cao Shuo, didn't cheat you this time, right?" ”

"Aha, you are really my good son!" Cao Cao was now laughing happily.

"I guess you don't know that cotton can not only keep out the cold in winter, but also weave cloth!" Cao Shuo said leisurely: "The clothes made of this thing are really much better than any silk linen, and when worn in cotton cloth, it can be said that you don't feel any pain of friction!" ”

"Huh? Can this cotton still be weaved? ”

When everyone heard this, they were immediately surprised and delighted.

The benefits of cotton are too many!

"Come, see how this cotton becomes cotton!"

Cao Shuo smiled, and then led everyone to a cotton factory that had been opened before.

Most of the people working here are women, and Cao Shuo has completely sorted out the workflow for them a long time ago.

Now these women come to work in Cao Shuo every day, and Cao Shuo pays them to start work.

"Wow!"

When Cao Cao saw such a cotton factory, he almost jumped up with excitement.

This is to be done all over the country...... I don't know how many benefits there are!
