When Chen Li and Cao Shuo introduced the warship, they went through a lot of difficulties.

Cao Shuo also knew that what was standing on it now was the first warship of the Three Kingdoms era.

During the construction, the craftsmen must have encountered many difficulties, but in the end, they solved them perfectly.

Standing at the bow of the boat, Cao Shuo looked at the rough sea below, and his heart was also very excited.

In the future, there will definitely be more and more warships designed by craftsmen in the Dahan.

"This time I want to go north to Goryeo, and the warship said that it will definitely work!"

Cao Shuo smiled slightly and said to the craftsman beside him:

"You are the ones who have worked hard for the Great Han, I will go back and reward you!"

In history, when Li Shimin first conquered Goryeo, he also relied on landing by sea, and then cooperated with the infantry to flank and easily take it.

And now that Cao Shuo has a warship, he can also attack from both sides, and he has almost a ten-percent chance of winning.

A few days later, Cao Shuo received the news that Goryeo refused to surrender.

"Hehe, this Goryeo clan really won't surrender!"

At this time, Goryeo had also been putting forward conditions, hoping to vassalize the Han and retain part of their culture.

"Now they're thinking too much!"

Cao Shuo just smiled coldly:

"I want to pretend to surrender again, and then make trouble after a while, it's really yours!"

"What are we going to do this time?" Cao Cao asked Cao Shuo, and he also believed that Cao Shuo must have come up with a plan.

"Haha, of course we fought!"

Cao Cao smiled slightly, took out the map and said: "Now that we have warships, we can send thousands of troops to land from the coast, and then send troops from the north to attack, it is not too easy to take down the Goryeo clan!" ”

"You mean... And send troops from the sea? ”

Hearing this, Cao Cao suddenly showed a puzzled look:

"Even if the troops are sent from the northernmost port now, there is still a distance from the Goryeo clan, and during this period, it is easy to have accidents!"

Most of the ships of the Three Kingdoms period were built of wood, and navigation depended on wind power, and the exact time is indeed relatively inaccurate.

In addition, most of Cao Cao's soldiers were northerners and had a natural fear of water.

"Haha, the previous ships were indeed very prone to accidents!"

Cao Shuo laughed:

"Daddy, you don't know that my ship has been built! Although there is only one, it is definitely not a problem to be able to reach 3,000 troops! ”

"What!"

Cao Cao's eyes widened in surprise:

"Three thousand troops? A ship? What does that look like! ”

When the other people present heard the news, their hearts trembled.

One warship can reach 3,000 troops...

How big does that ship have to be?

"If it is really according to the plan of Cao Shuo Gongzi, if there are really 3,000 troops to encircle and suppress from overseas, it is indeed very easy to take Goryeo."

Guo Jia touched his beard and said.

The main reason why the Goryeo clan has not been won before is because there is only one army.

And because of the battle line and the weather, it was impossible for the Han soldiers to travel long distances.

By the time they actually arrived, their strength would no longer be able to compete with the Goryeo clan.

But now there is this line at sea...

Yes, indeed!

"This time, daddy, you just leave it to me!"

Cao Shuo smiled slightly, patted his chest and said:

"I'll personally lead the troops over this time, but I want my dad to keep it a secret!"

The reason why he chose to lead the troops in person is actually very simple, Cao Shuo doesn't want others to know.

For example, a detailed map of the Goryeo clan.

It's not a thing of this era at all.

And with the map, it can be said to be of great help to the march and fight.

And because he is familiar with the terrain, Cao Shuo can also change his battle line at any time.

On the other hand, Cao Shuo had to deal with the relationship between the local residents and the soldiers.

Conquest was not killing, and if Cao Shuo wanted them to accept the culture of the Han Dynasty, he had to distinguish between the Goryeo soldiers and the inhabitants.

For those who want to resist, Cao Shuo will definitely make them suffer, while the innocent civilians will be recovered as much as possible.

"You're going to be ... Why do you want to lead the team yourself? Cao Cao asked Cao Shuo at this time.

"I haven't led troops for so long, so it's time to be active, and... I want my big brother to come with me this time. Cao Shuo said again.

Of course, Cao Shuo did this for Cao Ang's merits.

Now Cao Ang actually has a lot of combat exploits, but if he really convinces others, it still takes a period of accumulation.

"Take Cao Ang... That's great. Cao Cao muttered.

He knew very well in his heart that Cao Shuo was thinking about Cao Ang.

As a father and monarch, Cao Cao was also very relieved to see the coordinated development of Cao Shuo and Cao Ang.

In the past few days, the soldiers of the northern expedition to Goryeo have been ready.

The army set off from the Xuchang barracks, and when it passed through the town, it was also warmly welcomed by the people.

Public opinion is the most important thing in a country, and Cao Shuo actually publicized this northern expedition in magazines very early on.

"If Goryeo has a heart of disobedience and wants to cause chaos on the frontier, he will be punished."

This is Cao Shuo's slogan to the people.

From ancient times to the present, wars need a slogan and appease public opinion.

And now, Cao Shuo's magazine has a very high degree of convincing, and the people believe in the information on it.

The other is the material aspect of the war.

In addition to some necessities such as grain, grass and horses, Cao Shuo also distributed energy drinks to the soldiers.

Coupled with the now newly built concrete roads, they marched very fast.

Only ten days later, the army marched out of Youju and entered the range of Goryeo.

Goryeo is not idle here.

They also received the news that Cao Cao would come over recently, and they have been preparing for battle recently.

However, unlike Cao Shuo, the Goryeo clan did not dare to let people out, and only dared to be obscene in the city.

For some villages outside the city, Cao Shuo ordered that no soldiers should be allowed to intrude, otherwise they would be dealt with by military law.

Now Cao Shuo's soldiers are not short of food and grass, and there is no shortage of fortresses.

If this is to harass the common people again, it is too much.

In addition, even if there were really ordinary people communicating with the Koreans in the city, Cao Shuo didn't care at all.

This time, I came here to defeat the Koreans who dared to fight against the Han and let them taste the power of artillery.

Because of the long journey, Cao Shuo did not choose to bring a lot, and only disassembled five artillery pieces for siege.

In addition, because of the mountains and mountains here in Goryeo, it is really inconvenient to transport artillery, and even if you really bring a lot of it, it can only be a burden.

The purpose of the artillery in this operation is to open the city gates, nothing more.
