On both sides of the Haihe River, there is a scene of chaos. For the first time, the forts along the river have been set on fire.

In the darkness of the night, the Mongolian Daru Hua Chibatulu, who had abandoned Haijin Town, was riding a horse and standing on a raised plateau, staring blankly at the surroundings.

Why haven't Yanjing's reinforcements come yet? How could Great Mongolia be born to watch the Han army come and go freely in the hinterland of Yanyun?

This Han army and horses deep into the coastal river are only about 10,000, and they are not big soldiers, although they can fight, but with the soldiers and horses of the Great Mongolia, they can be killed by using people.

But why did the Great Khan of Jinlianchuan seem to be frightened, why didn't he dare to send troops to fight these Southern Barbarian Han people?

Not only did he send large soldiers over, but he also sent an edict to Hebei and Yanyun Zhulu, ordering them to stick to the city, clear the wilderness, and not fight with thieves in the wilderness.

The Mongols were strong and clear, and they did not dare to fight with the Han Chinese!?

Moreover, this group of Han people who came along the Haihe River is not the same as the soft Han army that likes to "commit no crime in autumn". I heard from a few Semu people who escaped from Haijin City for nine lives, saying that after the Han people who killed them entered Haijin City, they arrested all Semu and Mongolian women as slaves!

What's more, all those who resisted or were useless were killed on the spot, and many of them were wounded in previous battles......

This style looks like a Mongolian!

Moreover, they will not let go of the Han people in Haijin Town! They were all organized into a team, boarded the boat and pulled away under the "protection" of the soldiers, and all went to the lower reaches of the Haihe River.

After taking away the Han people and Semu people in Haijin Town, these two days. Chen Jiajun extended his claws to the fortresses on both sides of the Haihe River. All the people in the fort (of course, all Han Chinese) were forced to board ships and evacuate, just like the people of Haijin Town! Where the fortress resists. All of them were blasted away!

Tonight, this group of Han robbers is setting fire to the stockades along the Haihe River again!

Straight sissy thief's. It's about grabbing a handful and leaving! If the Great Khan's reinforcements don't come, the Han robbers will really flee, and the wives and daughters left behind by the unlucky Mongols in Haijin Town will never be recovered. The Mongols' wives and daughters actually robbed the Han people, and they didn't dare to take it back, how could there be such a ridiculous thing in this world!?

However, this Mongolian Daru Huachi did not expect that Chen Dexing had no intention of grabbing a handful and leaving. Although he has gained a lot on both sides of the Haihe River this time, the population alone has reached no less than 50,000 - considering that the total population of the northern Han region is about 10 million, this number is really a lot!

As for the riches, they are even more abundant. Both sides of the Haihe River are also considered a happy land in the northern Han land, after all, it is directly under the jurisdiction of Kublai Khan. Haijin Town is also the first commercial port in Yanyun. Or the old battalion of the Mongolian naval army.

There are no less than 100 ships in the sea alone! There are also twenty spinnakers that have already been built! Together with the timber for the shipbuilding, the freshly sewn sails, and the craftsmen, they all fell into the hands of Chen Dexing! They were also pulled together to Tanggu Port in the lower reaches of the Haihe River.

And this Tanggu Port and the Tanggu City that coexists with it are the strongholds that Chen Dexing plans to stay on the land of Yanyun for a long time - blocking Kublai Khan's door, and he can slap Kublai Khan in the face at any time!

If Kublai Khan could endure such a thing, then he would not be a big sweat, but a big shrunken turtle!

Just as the fortresses on both sides of the Haihe River were set on fire, the initiator of this qiē, Chen Dexing, who was soon to be called "Ming Kou" or "Ming Thief" by the Mongols, had also retreated to the mouth of the Haihe River. He was standing in the cabin of the battleship "Thunderbolt", looking at the dark and dreary Tanggu City construction site and muttering silently.

Tanggu City is divided into two cities, north and south, and the north city is built in a small river loop called Guojiabao, facing the river on three sides. Only the northern side is easily accessible land. It is now protected by ditches and wooden fences. Within the wooden fence, watchtowers, forts and wharves were also built, and cannons could be erected on the forts to block large sections of the Haihe River.

Tanggu South City is located in the southeast of Beicheng. It faces the north city across the river from east to west (because of the meandering of the river, the north and south cities face each other from east to west). The two cities were planned to be connected by pontoon bridges, with each other as horns. Because the north city is upstream of the south city. Therefore, when the Beicheng Fort blocked the river, the banks of the Nancheng were ideal wharves and berths. More than 200 ships of all kinds crowded there, forming a long queue of more than 10 miles. The area of the southern city is also larger than that of the northern city, and the wooden fences and moats for defense are built in the south and east of the city, of which the east of the city is based on a large saline-alkali beach (beach), which is estimated to be the location of the port of Tianjin in later generations.

The reason why this is so is that the General Staff of the Northern Expeditionary Army believes that Kublai Khan is very likely to deploy troops to counterattack immediately after the Northern Expeditionary Army lands. Therefore, the Northern Expeditionary Army needed to build fortifications in the shortest possible time.

But contrary to Chen Dexing's expectations, Kublai Khan seemed to have incarnated into the Teenage Mutant Ninja Turtles, no matter how Chen Dexing slapped his face, he just didn't show his head. Except for a few Mongol cavalry wandering on both sides of the Haihe River, covering the battlefield, there was no trace of the Mongol army!

And Chen Dexing, who lacked cavalry, was reluctant to scatter his only 1,500 cavalry out to search, and he couldn't figure out Kublai Khan's deployment for a while. It was still calm before the storm, and I didn't dare to take it lightly, so I could only urge the people to hurry up and build Tanggu City one day earlier, so that I could put my heart down one day earlier.

The sound of footsteps sounded behind him, and Chen Dexing looked back and saw that it was Zhang Shijie, the military division of the General Staff. Although Zhang Shijie was not very familiar with water warfare, his skills on land, especially his familiarity with the Beidi and Mongol armies, was definitely the first among the Northern Expeditionary Army. That's why he got the position of military advisor.

"What are you doing here, my lord? There is nothing to look forward to, Tanggu Beicheng has begun to take shape, and there is nothing to be afraid of even if the Tartars come. According to the battle to the death of the city, if there is no cannon and thunder made by the king, this city may be difficult to defend. But with cannons, thunder, ...... For the current city defense of Tanggu, give me 5,000 soldiers to block 100,000 Tartars! ”

Chen Dexing smiled faintly: "If only there were really 100,000 Tartars gathered in Tanggu." We use 15,000 people to hang 100,000 Tartars here in Tanggu, as long as there is a stalemate, the north and south heroes know how to choose. That Yidu Xianggong will not always be rubbing, as long as Yan Yun is here to fight well. We at least have the land of Liaodong and Goryeo. ”

Zhang Shijie sighed: "Is the king worried that Yidu Xianggong will not send troops?" This is not necessary, Yidu Xianggong is a little soft, but Yidu Bing is still very strong. The Han army in the area of Xu Pi has also always obeyed Yidu. I heard that Shuntian Zhang Rou and Jinan Zhang Rong are ready to attach to Yidu. Yidu's available soldiers should be no less than 100,000. This is the capital that can become a hegemon, and Yidu Xianggong will not do nothing...... It's just a pity! ”

This is a pity, naturally Chen Dexing can't enter Yanjing.

Chen Dexing shook his head: "There's no pity, we can't take this Yanyun in the first place...... Even while Kublai Khan's army was outside, he barely fought down, and he didn't have enough strength to hold it. Moreover, the people of Yanyun have let the Tartars rule for a long time, and they have long been afraid of it to the bones. How many people do you see these days?

This day is not in me, and Kublai Khan also occupies some, if you go deep into the hinterland of Yanyun, you will lose the geographical advantage. If I have 50,000 land divisions, I should fight bravely, take Yanjing quickly, close Juyong, and pacify the northland. But I only have 15,000 troops, and I am alone in the depths, and I have no chance of victory.

In this battle, my purpose is not to claim the title of emperor according to Yan, but to pull Kublai Khan off the horse, let the Han marquis of the Central Plains rise up against him, and let Ali Buge and Kublai Khan continue to fight against him. ”

That's the benefit of knowing where history is going. Chen Dexing knows very well who the big boss of this era is, not Ali Buge, not Li Pu, not Jia Yidao, but Kublai Khan! If you want to reverse the general trend of the Han family, you must try your best to weaken the big boss of Kublai Khan.

But the big boss is the big boss, even if he is slapped in the face by someone blocking the door, he will not show any flaws. The imaginary bloody battle at the mouth of the Haihe River seems to be going to happen.

Chen Dexing shook his head, turned around and walked towards the cabin, and Zhang Shijie hurriedly followed. Instead of going to his bedroom, Chen Dexing went into the cabin used as a temporary headquarters. The oil lamps and candles inside were still lit, and several staff officers were whispering about the plan for the army to march out. Seeing Chen Dexing and Zhang Shijie coming in, they stood up and saluted.

"Go ahead." Chen Dexing just whispered an order, and then came to the wooden table where the construction drawings of Tanggu City were placed, and Zhang Shijie also followed.

The drawings show two very strange-looking castles, which are not at all the same as the current stockade enclosed by two wooden fences. The drawings show two castles that resemble bastions, of course, not built on all sides, but on the side close to the land, there are cannon-prismatic bastions and concave polygonal defense systems.

It is a defensive system consisting of two bastions protruding from each end of the city wall, a sunken wall and a wide moat—this defensive system is the inevitable product of the extensive use of artillery, and the protruding bastions can use the side fire of the cannon to block the route of the attack on the city wall. At the same time, two or more protruding bastions can provide fire support to each other. There are almost no dead spots for shotguns!

"The Mongols don't know when they will come, and relying on a wooden city is always unpleasant, and they have to build the fortress as much as possible." Chen Dexing tapped the drawings lightly and said in a low voice, "Military Division, I will leave 2 divisions and artillery brigades for you, and the people brought from Goryeo will also be left." The north and south castles are to be repaired within three months. You don't need to ask about anything else, just repair the city. If the Mongols come to provoke, don't go to war. ”

"I understand this!" Zhang Shijie nodded, and said with a smile: "King, don't worry, Kublai Khan was a shrinking turtle in Yanjing, and I didn't come out of the Tanggu wall, no matter how tempted the Mongols were, they always repaired the city with their heads bored, and they didn't go out."
