As for Cao Shuo...

He was ready to hide from the world and the court that he was researching unearthed guns.

Because it will be a long time before the earth gun is really put into the battlefield.

And now the smelting of metals also needs to be gradually upgraded, and there is really no need to shout about this matter.

Cao Shuo went out of the mansion and went directly to the Institute of Science and Technology.

Here, it is the location where Cao Shuo is looking for someone to study the steam engine.

And the drawings of the steam engine were also drawn by Cao Shuo a long time ago, but they have never had a chance to use them.

Moreover...

The steam engine is really too difficult, even Cao Shuo, who came from the postmodern era, has been studying it for a long time.

Also, it takes a lot of time to build a steam engine.

Welding technology of this era... It's really bad, all Cao Shuo can do is continue to research.

The key to the steam engine is how to be airtight and use the right metal.

From that point alone, it's definitely a problem.

If the parts are not connected tightly enough, the steam engine will explode and fall apart as soon as it starts.

And there is also a lot of research on the use of metals.

But fortunately, Cao Shuo is not in a hurry.

At present, the research direction of the scientific research institute is gradually developing towards a good place.

In addition, the production of parts for the steam engine is also a very difficult task, which requires a lot of experiments.

After taking a closer look here, Cao Shuo came to Cao Cao's mansion again.

The reason for coming here is also very simple, it is to brush up on experience...

"What? We have a Goryeo envoy here? ”

But just when Cao Shuo arrived at the door, he suddenly heard such a news.

"What? Now the Goryeo envoy is coming? ”

Cao Shuo was also confused, and then came directly to Cao Cao: "Dad, the envoy from Gaoli, what's going on?" ”

"Haha, I'll tell you about it!"

As soon as Cao Cao saw Cao Shuo, he laughed and said:

"Now Goryeo has sent an envoy who is willing to make an offering every year and become our courtier!"

"Hehe..."

Cao Shuo smiled coldly and said directly:

"Dad, you don't think that if you do this, Goryeo will be grateful to you, right?"

Now that Cao Cao has occupied the north, the Goryeo clan has been suing for peace, and only today did they receive the envoy.

And Cao Shuo to them...

There is not the slightest bit of goodwill.

"Cao Shuo... Do you think there's something wrong? Cao Cao saw Cao Shuo's sudden seriousness, and said with a puzzled expression.

In Cao Cao's view, this is a good thing.

After accepting Goryeo as his courtier, he can receive a large amount of money every year, and.. What a thing to be proud of!

In ancient and modern times, no one in China and abroad has ever been able to accept Goryeo, but now that Cao Cao has succeeded in making them surrender, isn't it worth rejoicing?

"Dad, have you forgotten the Huns and the Wuhuan clan?"

Cao Shuo smiled and said:

"Back then, when our Han army was strong, they bowed down to us and paid the tribute every year."

"But once we are in crisis, they will take advantage of the opportunity to make a mess and grab the territory of the population."

"Now is the time when we are strong, they will definitely turn into licking dogs, but once there is a problem, their true nature will definitely be exposed at that time!"

...

"This.."

Cao Cao listened to these words, and immediately began to think.

At the same time, the other strategists in the hall were also lost in thought.

I have to say that what Cao Shuo said is indeed very right.

Just now they felt that it was a supreme honor for Goryeo to come to pay tribute!

"I think what Cao Shuo Gongzi said is right, but..."

At this time, Jia Xu stood up and said:

"But it's a good thing that they're coming to pay tribute now! And we are so strong now that for at least fifty years, Goryeo will not fight our idea! ”

"Hehe, in fifty years, what about fifty years from now?"

Cao Shuo sneered and asked Jia Xu.

Cao Shuo, who is very familiar with history, does not want to see the Han Dynasty invaded by foreigners again.

In the original history, the collapse of the Jin Dynasty was inseparable from the invasion of foreign tribes.

Although Cao Cao is now strong and invincible in foreign wars, no one in the north can fight with Cao Cao.

But...

Who would dare to say after that?

Fifty years is a long time for a person, but in the long river of history, it is as small as a speck of dust.

In other words, who dares to guarantee that the generation after Cao Ang will not be invaded by foreign races?

At that time, if there is a little accident, Goryeo will definitely take the opportunity to make trouble!

"Cao Shuo, you... What does that mean exactly? ”

Cao Cao calmed down, took a deep breath and said.

As a monarch, Cao Cao actually understands Cao Shuo very well.

The thousands of generations of the Han Dynasty are not Cao Cao's alone, but since Cao Cao is capable now, he has to pave the way for those who follow.

Just like Qin Shi Huang, the reason why he has been trying his best to redeem his troops is that he hopes that the Han Dynasty will not be invaded by foreign tribes.

If you want to develop, you must be internally unstable.

But Qin Shi Huang was very sorry, because the economy and agriculture could not keep up, and finally led to his own demise.

Speaking of Yang Guang, he has also been expanding his forces throughout his life.

But to say, what did he do wrong?

Yang Guang's development of military strength was to stabilize the Han nation.

This general idea was not wrong, but he, like Qin Shi Huang, lost in a hurry.

In the end, it led to the misery of the people and the overthrow of the dynasty.

And Cao Cao at this time, because of Cao Shuo's relationship, is completely different.

"What we're going to do now is actually quite simple!"

At this time, Cao Shuo smiled slightly and said:

"Now there are too many alien races in the north, we can make them all submit, if they oppose it, directly send troops to exterminate it!"

"For those who have submitted to us, we will send troops directly to station, and then quickly build concrete roads, and then convey our culture to them, so that their descendants can be infected by us."

"Only by doing this can we really eliminate the foreign races and make the Han immortal!"

...

Cao Shuo knows the importance of culture best.

At that time, all the foreigners were barbarians, and it was only a temporary prosperity at this time, and it would be difficult to say at that time after a few hundred years.

Why is Huaxia the first of the four ancient kingdoms?

Because in the land of China, no matter how turbulent it is, the culture is always the Chinese civilization.

This kind of culture, which binds all the people together, is still a great nation even if there are any changes.

"This..."

When everyone heard this, they were very impressed.

Cao Shuo's understanding was completely beyond all the strategists, and the generals were all contemplative at this time:

What exactly is force for?

This question lingers in everyone's minds.
