"Lord!"

At this moment, a herald rushed in, panting and said to Cao Cao:

"Now there is a person outside the door who asks to see him, claiming to be Xiliang Ma Chao!"

"Ma Chao!"

Liu Bei's face suddenly bloomed with a smile:

"Ma Chao is a peerless ruthless man, the real king of Xiliang, and now he has taken refuge in him...... Is this the benefit that Mr. Pang Tong said? ”

In this regard, Pang Tong just smiled slightly, and then said:

"Yes, Ma Chao will definitely come to the lord's place, and it is also the only place for him to go!"

"Hahaha, let's go out and meet him!"

Afterwards, Liu Bei took everyone out of the city to greet his general Ma Chao.

Since then, Liu Bei has gained another general, and his strength has risen a little more.

And Cao Shuo at this time is here...... is still paying attention to the word development, and he doesn't care about the actions of Liu Bei and Sun Quan at all.

Cao Shuo deeply knew that it was not the troops and generals who changed the current battle situation at all.

In the face of absolute hard power, Liu Bei's lies are as fragile as a blank sheet of paper.

Now Cao Shuo is working on a new generation of artillery.

Mortars are powerful and easy to carry......

But in the face of siege, it is completely useless.

What Cao Shuo is studying now is an anti-tank gun, which is useful for siege cities.

The drawings of this anti-tank gun, Cao Shuo had drawn out by lottery before, and now he is letting his metallurgists start to study it.

Although according to the current Cao Shuo's craftsmanship and level......

It was a bit difficult to make an anti-tank gun that was exactly like a modern one.

But after the drawings have been modified and reduced in equal proportions...... If you go and make the original, you might be able to make it.

Can...... There is also a huge problem with the casting of anti-tank guns.

That is the material copper.

Looking at the whole of China, in fact, the storage of copper is quite good.

But now in the Three Kingdoms period, it was very difficult to mine iron ores, and copper was still a rare item in this era.

There are relatively large copper mines in China, but most of them are now in Jiangxi, that is, Sun Quan's territory.

Cao Shuo has also been sending people to collect copper and prepare to start casting forts.

It doesn't take too much, a maximum of a hundred mobile anti-aircraft guns, which can definitely change the current situation of the battle.

As for making ...... out of pure steel

It's completely useless now, and the level of smelting simply can't do it.

Although Cao Shuo now has all the alchemy treasures, it is estimated that he will have to wait hundreds of years to make something as pure as a steel cannon.

Therefore, now that Cao Shuo wants to change the tide of the war and smelt steel, the only thing he can do is to quickly find copper mines, collect copper ores, and then go to anti-aircraft guns.

Cao Shuo can now imagine what kind of scene it was like to have soldiers carry a hundred anti-aircraft guns to fire at the city wall when he was fighting against Liu Bei.

At that time, even if they are defending the Great Wall, they will definitely collapse directly.

As for the stratagem or something......

It's even more.

Then, it's time to swipe your points!

On this day, Cao Shuo was busy with work, and when he was idle, he went to Cao Cao to play (brush points).

But as soon as he arrived at the door, Cao Shuo learned that Cao Cao was now sick.

"Ah......h

Hearing this, Cao Shuo himself was slightly stunned, and then realized that Cao Cao was no longer the old man who had seven times a night.

It seems that Cao Cao's health is not good.

"Doctor...... I'm a healer! ”

At this moment, Cao Shuo was stunned.

Originally, the skill that Cao Shuo obtained by lottery with merit points was medical skills.

Although this skill is not very practical in normal times, it can play a key role when someone around you is sick.

And Cao Shuo's own other exploits are worth ......

It has been exchanged for smelting skills and physical skills, and now there are a lot of merit points in the warehouse.

"Hey, see my dad!"

Cao Shuo smiled slightly, and walked towards Cao Cao's mansion with his hands behind his back.

Cao Shuo won a lot of medicines in the lottery before, but none of them were used by Cao Cao.

Because......

Cao Cao's health was very good, and in history, Cao Cao lived for a long time.

But even so, Cao Cao is now an old man, fighting in the south and north all the year round, and his body is naturally unbearable.

"Get out of the way, I'm coming to see my dad!"

Cao Shuo pushed away the guards at the door and crept in.

In the inner room, an old man's voice came:

"Prime Minister Cao, I have now prescribed you three pairs of medicines, which can temporarily relieve your headache."

"I guess I'll feel a lot better after eating, and you have to pay attention to your body!"

"Headache is a disease, generally because of restlessness, consuming too much mind to boil out, you are now in a hurry, you should pay more attention to the body."

……

"Hahaha, doctor, thank you so much this time."

Cao ** Lang laughed: "I have improved a lot after taking your medicine before, and it is estimated that there will be no problem in a few days, as for the consumption of mind, there is no way, right?" ”

"I hope Prime Minister Cao Cheng can recover soon, and the villain will retire first."

At this moment, the old man turned his head, and Cao Shuo suddenly realized who this old man was.

Hua Tuo!

What a miracle healer!

Can you let him go now?

"Doctor Hua Tuo, your reputation for excellent medical skills is resounding throughout China, and my father has been ill for a long time, why don't you stay here now?"

At this moment, Cao Cao sat up straight and said to Hua Tuo with a smile on his face.

"Thank you, Prime Minister, but the villain still has to save the people, and I can't be in one place all the time, I'm really sorry." Hua Tuo said euphemistically to Cao Cao.

"If you have been in Xuchang now, I can let you open the best medical hall, and it would be good to help the world like this!" Cao Cao still continued to stay.

"I just want to go to more places and try to see more people, thank you so much." In this regard, Hua Tuo still refused.

"Then you go down and rest first, I asked someone to prepare the best courtyard for you, rest for a few days first, and by the way, you can see the people in Xuchang and the like." Cao Cao was not too reluctant, and let Hua Tuo go down to rest first.

At this time, Cao Shuo happened to have a face-to-face with Hua Tuo.

"Hua Tuo's divine healing!" Cao Shuo said to Hua Tuo with an innocent face.

Immediately, the two exchanged pleasantries and did not speak again.

The reason why Cao Shuo did not directly express his retention to Hua Tuo was because he felt that now was not the best time.

I'll visit you later...... The effect will be a little better.

Now it's better to go see Daddy first.

"Cao Shuo, you're here!"

Seeing Cao Shuo, a smile bloomed on Cao Cao's old face.

"Dad, are you okay now?"

Saying that, Cao Shuo also paid attention to Cao Cao, and prepared to directly prescribe medicine to Cao Cao.

Although it is said...... Traditional Chinese medicine is actually more powerful than Western medicine, but now Cao Cao still has to go to the court every day to deal with official affairs, but it is better to do both!
