Peek at my diary, Cao Cao dominates the Three Kingdoms

Like in the Western Han Dynasty, there was a man named Chunyu Yi in Shandong,

He has been fond of medicine since he was a child. In order to study medicine, he traveled around and learned various medical skills and prescriptions.

But in the end, he still did not choose a doctor as his career, but became a head of Taicang who managed the granary and ate the imperial grain.

There is another person we are more familiar with, that is, the later Changsha prefect Zhang Zhongjing.

Zhang Zhongjing also liked medicine since he was a child. In order to study medicine, he devoted himself to research and read medical books extensively.

However, he himself came from a bureaucratic family, and later he was able to serve as the prefect of Changsha County by virtue of his qualification of "holding filial piety and honesty", and he did not choose the profession of a doctor.

Therefore, although Tai Shici would be a little surprised, he would not find it unbelievable.

Tai Shici also sought medical treatment everywhere for his old mother's illness. He saw many doctors, big and small, but there was no good effect.

Seeing that his old lady's health was getting worse and worse, Tai Shici was not to mention how anxious he was.

At this moment, hearing that Lu Yan seemed to be able to cure illnesses, Tai Shici's hope was kindled again.

Lu Yan's keen senses allowed him to immediately discover Tai Shici who was hesitant to speak,

But because he only has the medical skill of "not stabbing people to death", he can only say with a wry smile: "I have just started to study medical books. If I am not good at studying medicine, I dare not treat people's diseases without authorization."

When Tai Shici heard this, the light in his eyes quickly dimmed, "I just started studying medicine... It seems that I still can't have any hope..."

However, Lu Yan changed the subject and said:

"However, I have already sent someone to look for the genius doctor Hua Tuo. If he can be found, Zhicai's illness will not be a major problem."

These words seemed to be addressed to Guo Jia, but they also seemed to be addressed to Tai Shici.

In Lu Yan's letter to Tai Shici, he did not mention treating his mother's illness.

After all, there is no shadow of Hua Tuo yet.

If you draw a big pie too early and fail to realize it, it will only push people further and further away.

"Hua Tuo!!!"

Of course, Hua Tuo and Tai Shici had also heard of the genius doctor.

The most widely circulated rumor is this:

There are two military officials, both with fever and headache, with the same symptoms,

But the prescription Hua Tuo gave them was quite different.One used sweating medicine and the other took laxative medicine. The two felt strange, but they both recovered after taking the medicine.

It turned out that after Hua Tuo's examination, he knew that one was an exterior syndrome, which could be resolved by sweating; the other was interior heat syndrome, which was difficult to treat without diarrhea.

There are other big and small stories, anyway, they are talking about Hua Tuo's medical skills, God!

Guo Jia seems to be very worried about the health of his friend Xi Zhicai, and he also knows that Lu Yan is sending people to look for Hua Tuo.

However, Hua Tuo traveled around the world to practice medicine and see patients.

"Hey... I hope Zhizhi can survive until the day Hua Tuo is found."

Seeing that Guo Jia seemed a little sentimental, Lu Yan couldn't help but said:

"Feng Xiao, you should take care of yourself first. Zhicai has taken my ancestral special elixir, and his physical condition has improved somewhat.

On the contrary, it's you who indulge in sex and wine every day, and sooner or later you will be hollowed out by them! "

When Guo Jia heard this, a mystery that had troubled him for a long time seemed to be solved.

"Hey! When I saw Zhicai last time, I felt that he was much stronger!" Guo Jia murmured to himself, "He coughed when I said a few words to him before, and he would cough if I said a few more words to him." breathless...

But the last time I saw him in Juancheng, I noticed that not only did his face turn ruddy, but he even spoke with strength..."

Thinking of this, Guo Jia stared at Lu Yan with bright eyes, and said, "Good guy! You have such a good thing and don't share it with me?"

After finishing speaking, Guo Jia rushed to Lu Yan's side, and then groped on him: "It happens that I feel a little powerless recently...Hurry up! Take out ten or eight to adjust my body!"

"Get out! Don't touch!" Lu Yan knocked off Guo Jia's hands that were groping in his arms, and said loudly:

"That's the elixir handed down by the ancestor (xi), and I only have one!

Do you think it's eating beans, and give you ten or eight for you to chew and play? "

"Hmph! You're stingy!" Guo Jia also knew that such a magic medicine was not just available,

It's just that he still snorted dissatisfiedly, and then he returned to his seat in a rage.

Tai Shici felt dizzy and wanted to vomit...

His heart had been following the conversation between Lu Yan and Guo Jia just now,

I was lifted up and pressed down, then lifted up again, and finally pressed down again, "It's a mentality, this is it!"

After dismissing Guo Jia, Lu Yan had time to turn to Tai Shici and said:

"Ziyi, I know you are worried about your mother's condition.

Don't worry, once I get the elixir again, I will give it to your mother as soon as possible. "

"Lu Yan! Wo Ri, you are an immortal!" Guo Jia immediately exploded when he heard this, and rushed towards Lu Yan again, "Didn't you just say that it was an ancestral elixir? Isn't it the only one?

Why is it now available again?

You think I'm someone Guo so I can't be fooled? ? ? "

Lu Yan raised his hand one to three feet to block Guo Jia one meter away.

Looking at Guo Jia's flailing teeth and claws but helpless appearance,

A bright smile appeared on Lu Yan's face:

"Feng Xiao, you are just physically deficient, and you don't need a magic medicine like Pei Yuan Pill.

As long as you obediently accept my acupuncture every day, I guarantee that you will regain your glory in a short time! "

Guo Jiana was angry, but now he was blocked by a strange wall of energy invisible to the naked eye, so he could only take a step back and point to Lu Yan to warn:

"Damn! Who said I can't get up? Let me tell you, we're acquainted, if you slander me again, I'll still sue you for slander!"

Guo Jia and Man Chong may not have noticed the peculiarity of the three-foot air wall, they just lived with Lu Yan for a long time, and their nerves are a little numb...

But the insiders Zhao Yun and Tai Shici were shocked!

Zhao Yun's shock was different from Tai Shici's,

He had seen Lu Yan cast a three-foot air wall before, but the three-foot air wall at that time would cause violent vibrations in the air, and people would see a "wind wall" that was visible to the naked eye.

But now, Lu Yan's three-foot air wall has completely calmed down, and the existence of the wall is almost invisible to the naked eye.

"This shows that the master's control of martial arts and internal strength has improved a lot! He really deserves to be an innate master, and his comprehension aptitude is so terrifying!"

Tai Shici was so shocked that he almost pulled off his beard, "What the hell! Am I hallucinating? Was that the breath of innate zhenqi just now? Could it really be innate zhenqi???"

Seeing Tai Shici's stunned look, Zhao Yun moved two steps sideways to Tai Shici's side, put his head close to Tai Shici's ear and whispered:

"Your perception is correct.

Mr. is an innate master!It may also be one of the only two geniuses at this time!

But it’s fine if you know it yourself, don’t go out and publicize it. "

After listening to Zhao Yun's words,

Tai Shici's expression at this moment,

It's like this o.0~!

Chapter 67 The Vision of the Special Forces and the Most Mysterious Department in Chenliu County

When I first met Lu Yan,

Tai Shici thought that Lu Yan was a literati and Confucian general who was good at people's livelihood, government affairs and leading the army.

Tai Shici, who originally decided to serve Lu Yan, was still a little proud in his heart, thinking that Lu Yan had made a lot of money by joining Lu Yan with such a courageous and resourceful talent.

But now he suddenly found out,

Not only is Lu Yan good at military affairs, but also in martial arts, he has reached a realm that Tai Shici couldn't even imagine, an innate realm!

"If you don't leave Donglai County, you don't know that there is another Lu Changsheng in this world!" Tai Shici was filled with emotions, and it was the first time that he realized what it means to be truly human beyond human beings and beyond the sky!

The more he knew about Lu Yan, the more pride in Tai Shici's heart was crushed.

"Even an outstanding person like Mr. Lu keeps learning new knowledge (medical skills) to enrich himself. What can I, Tai Shici, be proud of?"

After knowing that Lu Yan turned out to be an innate master, he finally buried the arrogance in his heart to the deepest part of his heart,

"No wonder Chenliu County has become a place outside the world!

With Mr.'s ability, I, Tai Shi Ci, may not even be able to hold a candle to him in this lifetime!

It is an honor in my life to be able to follow Mr. at your side in this life! "

So far, Tai Shici has completely returned to his heart.

......

Chuping four years, January.

Cao Cao has completely settled in Yanzhou,

The eight counties under the Yanzhou administration have followed the example of Chenliu County and completed the establishment of civilian and military settlements.

However, Cao Cao did not dare to imitate the lijia system and household registration system in Chenliu County, because this system would damage the fundamental interests of aristocratic families and arouse their resistance.

At least until Cao Cao completely controlled his own territory, he didn't dare to offend these local snakes too much.

Chenliu County, which carried out reforms first, is now getting better.

Although the first batch of spices hadn't been harvested yet, relying on the business opportunities brought by the large population flow, Chen Liu's tax revenue almost doubled last year!

Even better,

Boss Cao generously exempted Chenliu County from taxes for three years, so Lu Yan has a lot of working capital this year, feeling like an upstart.

With funds in hand,

Lu Yan began to work hard to improve the infrastructure of the workshop. Technology is the primary productive force. He still firmly remembered this sentence.

In the early years of the Eastern Han Dynasty, someone designed and manufactured a hydraulic blower for metal smelting and casting.

Its principle is to turn the water wheel through water,

Then a series of crankshafts, connecting rods, reciprocating rod devices, etc., convert the circular motion into the linear motion of the bellows.

In fact, if this procedure is reversed,

That is the conversion of the linear reciprocating motion of the piston of the steam engine to the circular motion. Metallurgical leather bags were used in my country's metallurgy at first, and there were four bags in the Warring States Period.

In the Han Dynasty, horse steaks, beef steaks and even water steaks were used.

In the Song Dynasty, there was a wooden fan similar to an accordion, which is a bellows with automatic valves.

Especially by the end of Ming Dynasty, piston blowers had appeared.

However, with the present technology, this level cannot be reached for the time being, and piston blowers cannot be produced.

The method of frying steel appeared in the Western Han Dynasty.

The smelting method is to heat the pig iron to a liquid or semi-liquid state, and then reduce the moss content of the pig iron by blowing air or adding fine ore powder to make it into steel.It gets its name because it needs to be stirred continuously during smelting, just like cooking.

On this basis, there is also a steel made by repeatedly folding, forging and deforming fried steel, which is called Bailian Steel.

Refined iron that has been repeatedly forged, one forged, one weighed and one lightened, until the weight is not lost, the sundries in the steel have been eliminated as much as possible, so that the composition tends to be uniform, the structure tends to be dense, and the performance of the steel is improved. It is very superior.

However, steelmaking and forging weapons are time-consuming and labor-intensive, and can only take the elite route, not suitable for mass production.

Fortunately, Lu Yan has another more powerful technique here, the method of pouring steel!

Lu Yan had obtained the drawings and technical descriptions of "Su Tie Dao: Steel Filling Method" from the system earlier.

But because Chen Liu was the place of the Fourth World War, it was not safe, so I didn't dare to take it out.

Now there is no threat from the outside of Chenliu County, and with money in hand,

Lu Yan began to promote the exploration and application of Guangang method, as well as the forging of Su Tiedao.

Lu Yan wanted Tai Shici to command a special army. In Lu Yan's vision, this army should be an infantry first.

The soldiers of this infantry,
