Of course, it is very uneconomical to kill all the people in Haijin Town. Chen Dexing's current plan is very big, not only to take Goryeo and the northeast, and get involved in Japan, but also to expand his power to the south, east, and west as much as possible, and turn all the wild lands within reach into a part of the future Chinese world!

And, of course, he has to fight against the most powerful empire the world has ever seen, the Great Mongols!

And the population in his hands is too small, basically counting the Koreans in Jeju Island, Ganghwa Island, Jindo Island, Geoje Island, Pusan and other places, and the few residents of Penghu Island, Yizhou Island and Yashan Island, it will not exceed 350,000. Even if you include the people in the territory where the kings of Goryeo can still control zhì, the total population is only 17.8 million.

Such a small number of people will be a large county in later generations, and under the technical conditions of the 13th century, the production that these populations can support is probably less than one-tenth of that of a county in later generations.

Therefore, Chen Dexing will not kill tens of thousands of people with the ability to work at one time. Nor will they let go of the Han people here in Haijin Town......

Under the threat of death, the people of Semu who were trapped on the wooden bridge of the Haihe River all dug out their hearts and thought of the ability to survive. Then one by one, they disembarked from the bridge and threw all their belongings onto a few designated wagons.

"Niccolò, we're going to lose a qiē......" Matteo leaned his head on his brother's shoulder and cried loudly, "We're going to become a slave, it's all over!" ”

"It's better to be a slave than to die, and maybe we'll have a chance to turn over......," Niccolò comforted his brother, but he felt the same despair.

The future of being a slave is clear! This Han Chinese army showed no signs of preferential treatment of the Semu people! Just look at the killing they did on the battlefield just now......

"But Niccolò, I don't know what we're capable of. We don't ...... anything but business and settling accounts," Matteo cried. "They're going to kill me and turn Sophia into a slave girl. Ten or even twenty men her every day, how can she stand it! ”

'How can you not stand it?' That woman is too hard to do, you can't be satisfied alone...... 'Niccolò wanted to tell Brother Sù something he didn't know, in fact his wife was a complete slut, including Niccolò himself, who was in a relationship with at least five wild men!

"She'll take care of her ......," Niccolò still didn't tell the truth, "I think if we show enough talent, the Han men will give Sophia back to you." ”

After using it, of course! Niccolò thought to himself, that wasn't a big deal for Sophia. Maybe she'll still feel like she's going to be alive and well.

"But what are we capable of?" Matteo cried and shook his head.

"What are you capable of?"

The brothers were soon brought before a somewhat brutal-looking officer, and beside him lay several corpses, all of them too old to have any special abilities, and no one could pay a ransom for them—the slave was not to be a slave!

"We ...... We'll do the deal! ”

"That's not going to work!"

What kind of ability is it to be able to do business? Oh, it's a skill, but it's useless. Chen Dexing didn't dare to give them the capital, so he let them go out to do business.

"Niccolò, we're going to die!" Matteo looked at the corpses. The whole body went limp, as if he was soon one of them.

"We know how to make glass, we were apprentices in the glass workshop when we were kids!" Niccolò really came up with something in a hurry.

"Anything else?"

"We, we speak Chinese, Mongolian, Dashi and Latin......"

"Hmm." The officer took out a pen and paper from a soldier beside him. Recorded it. Being able to make glass and speak four languages is indeed a skill. "Anything else?"

"We ...... We also traveled to Dashi, Tianzhu and Nanfan, and knew the routes between the east and the west well. ”

"Okay." The officer nodded. "You're capable." He pointed to his left, "Stand over there." Someone will ask you about your family, and you have to answer truthfully. Because you can live with your family. You can still keep a small amount of property...... If you didn't lie to me! ”

This time I'm really a slave! The two brothers looked at each other and smiled bitterly, and walked together in the direction the officer had pointed.

……

On a lucky ship with a load of more than 2,000 stones, Chen Dexing was standing on the bow with his arms crossed. His attention was not on the wooden bridge of the Haihe River, nor was it on the town of Haijin. There is no suspense in these two places, it is just how many colored slaves were caught, and how many Han merchants were plundered.

Slave...... Absolutely!

Chen Dexing was not an abolitionist. In the 13th century, slavery could not be abolished, the question was who would be the slave?

Of course, slaves also have to have an upward channel, otherwise how to motivate slaves to be positive? For example, these captured slaves were assigned to work in designated workshops, granges, or construction sites according to their talents. They will also receive a small amount of money, which they can save to redeem themselves and their families, and thus become free people.

If these slaves had special talents, they would have been paid more and treated better, such as living with their families, because they could redeem their freedom earlier because they had a higher income...... However, slaves with special talents will be worth more than ordinary slaves, and the ransom will be higher!

In addition, if these slaves can find friends and relatives who are willing to pay the ransom for them, they can also be freed early. But...... The people in Haijin Town can't help them, because these people will also become slaves of the Northern Expeditionary Army!

The second-class color is nothing in Chen Dexing's opinion, but the first-class Mongolia is still quite strong. His attention had now completely turned to the two Mongol thousand-man teams hovering seven or eight miles south of the Haihe River.

After a few glances with a telescope, Chen Dexing could determine that these formations were a little scattered, and the armor banners showed old tartars, and they could not attack the phalanx of his own foot soldiers at all.

These are the old and weak among the Tartars, although they can still fight on horseback, but their combat effectiveness is not good!

The infantry of the two brigades had lined up with their backs to the Haihe River, and they also pushed six cannons and six three-bow bed crossbows forward. He is confronting the Mongols in the distance. There are also several hundred cavalry of the Northern Expeditionary Army, which are also on the shore of the Haihe River, which have stopped their movement and are resting.

"Although the ginger is old, it tastes spicy!" Chen Dexing put down the binoculars and sighed softly.

Growing up in the decades-long war of Mongol conquest, the old pawn is really not so easy to deal with. Whether it is to drive Semu to fight under the city, or to lead the Mongolian horse team to abandon the city and wander, it is undoubtedly the best choice!

The town of Haijin did not have real walls and could not be defended at all. Fighting outside the city was not much different from defending the city, but it allowed the Mongol cavalry to jump to the periphery in time after the shape was unfavorable.

If you let people besiege the city, you can only destroy the whole army. And the two Mongol thousand-man troops who were completely annihilated would not pose any threat to Chen Dexing's rear road. In this way, Chen Dexing did not have to station heavy troops at the mouth of the Haihe River, and he could also sweep his troops around to coerce more Han people in the north.

However, the existence of these two thousand-strong cavalry teams made Chen Dexing unable to let go of his hands and feet, and could only confined to the banks of the Haihe River.

And this kind of flexible and mobile combat method that is not confined to one city and one place is actually the biggest advantage of the Mongolian cavalry over the Northern Expeditionary Army, which is equipped with bronze cannons!

"Your Highness, this is the old tactics of the Mongols, and they are not sure that they will not fight a decisive battle, but they will move around and deal with us. If we send foot riders to follow, they will go around in circles with us. When it comes to maneuvering in the wild, we're far behind them. Otherwise, one day they will be sleepy, and they will not be their opponents. If we ignore them, it will be difficult for our Horse Rangers to send out. The entire battlefield would be obscured by these two Mongol thousand-man troops. We can't grasp the reality of Yanjing, but they are always watching our every move, we can't go to Yanjing......"

Zhang Shijie, the military advisor of the Northern Expeditionary Army, went out with Chen Dexing, he was on the Jinghu and Lianghuai fronts for many years, and was very familiar with the tactics of the Mongols, and he was an expert in the use of cavalry in the Southern Song Dynasty.

Compared with charging and cavalry, the greater role of cavalry is actually to cover the battlefield. In the current war mode, the superior cavalry can cast a large number of horse rangers, and use the method of squad combat to drive the opponent's horse exploration rangers away from the battlefield.

In this way, the battlefield is one-way transparent to the side with cavalry advantage! The side that does not have the advantage of cavalry will become blind and deaf! Just like the Blue Army in the Liberation War, every move is in the hands of the Red side, and they are ignorant of the Red Party's actions.

This side without cavalry superiority can imagine how passive it is on the battlefield!

"It's okay," Chen Dexing shook his head and smiled at Zhang Shijie, "I didn't want to fight Yanjing, even if the Mongols controlled the battlefield. After receiving the population and goods of Haijin Town, let's leave and return to the mouth of the Haihe River to build a Tanggu City! Build a city at the gate of Kublai Khan's house and block his door! I'll see if Kublai Khan can endure this! ”

Zhang Shijie smiled: "If the Tartar can't bear it, he can only touch our copper wall with his head!" However, this Kublai Khan is not an idle person, but I am afraid that he can endure it for a while. ”

Chen Dexing said: "They have cavalry to control the plains, we have warships to control the sea, the decisive battle in Yanjing is not good for us, and the battle with the mouth of the Haihe River is our advantage." This battle depends on how thick-skinned Kublai Khan is! But it doesn't matter if he has a thick skin, when the city at the mouth of the Haihe River is built, we will move to Jinzhou, Liaodong!
