Liu Bu's strategy is a little different from that of sun Chengzong and Yuan Chonghuan, that is, he can build cities, but his way of building cities may be a little different from that of Daming. Daming builds cities on land, and Liu Bu's plan is to build cities all the way up the Liaohe River after they have a firm foothold in the southern Liaoning Sanwei, The place where the city is built must be along the river and can be reached by his Navy. As long as his Navy can arrive, it can quickly provide artillery support for them. Liu Bu believes and superstitious that if his Navy can be combined with his Navy, no army can defeat him and pose a threat to them.

Liu Bu's self-confidence stems from the fact that his warships have red cannon. These naval guns are the most powerful in the world. One shot can't be resisted by flesh and blood. The so-called shield car, a sharp weapon to deal with firearms, is actually a joke.

However, his cannons also have many shortcomings. The biggest disadvantage is that the red cannons of this era are generally bulky. They are generally up to 2000 kg, and the weight is up to 3000 kg, which means that dozens of people have to be sent to pull. Even if it is a horse, it needs more than 50 or 60 horses to pull, and this is still built in a flat and plain place, If there are any difficulties, the difficulty coefficient will double.

For example, when they were ready to chase Amin's troops, the enemy soldiers were very smart. They saw that the Ming army wanted to transport these heavy weapons against them, so they destroyed the road, that is, they ordered people to dig some pits and ditches on the road. In this way, it's not easy for you to transport your red cannon.

Liu Bu has acquired a large number of red cannon through trading with the Portuguese, and now they have mastered the technology of manufacturing cannon. They are in mass production. Their cannon can quickly equip his troops, but there is one such problem, that is, the transportation of cannon is still a difficult problem. In this era, there are no cars and tractors, Even there are no tires. If you want to pull these cannons, you can only rely on manpower. If you encounter bad roads, it is a disaster. If you encounter rain and muddy roads, you can't move. At that time, the combat effectiveness of his army will be greatly reduced and he will not be the opponent of others.

But they are not completely helpless. They have come up with various ways to transport their cannons, but they all involve huge human and material resources.

However, their navy is different. Their navy can be used at any time as long as the cannon is fixed on it, and they can move quickly on the ship. Liu Bu calls their navy a mobile fort, which exists as the support of infantry (at present).

Therefore, Liu Bu's plan is to build cities along the rivers and rivers, and then extend his power here. He does not pursue the five-year leveling of Liao as boasted by yuan Chonghuan. If five-year leveling is not ten years, ten-year leveling is not twenty years. As long as he builds all the way along the Liaohe River, he will eventually occupy Liaoyang and drive JianNu back to hetua.

Therefore, Liu bu he's current policy is very clear, he will not take the initiative to attack the island, and will not even attack Liaoyang or Guangning, etc., he has no interest in getting through the corridor of the Liao Xi corridor. He can not see a lot of woodlouse in Liao Yu. He knows these people will not be used for him, he can not control them, even these people. I'm afraid it will become my own burden. It's better for everyone to do their own work.

The imperial court is so stingy to give him an empty title. Do you want him to send troops to work hard? Therefore, Liu Bu directly ignored the imperial court's orders.

What he has to do now is to build their fortifications in the three cities based on the cities. They will build a three-dimensional fortification here, waiting for the slaves to attack them.

If other families or armies want to gain a foothold in southern Liaoning, there is an unavoidable problem, that is, the problem of food. Therefore, they inevitably let the army become a production and Construction Corps, farming while fighting, which can save manpower and material resources.

However, such problems will also lead to the counterattack of the same enemy, because JianNu is very familiar with the skill of the Ming army, that is, when you cultivate the land, he will not stop it, but when your rice is mature, they will send troops to rob, if they can't rob, they will send troops to burn, if they can't burn, they will send troops to prevent you from collecting, both sides for food, Repeated battles and contentions.

It can be said that the Ningjin defense line built in the Ming Dynasty is actually a product of this tactic. This is because JianNu controls the vast Liaohe plain. If they cultivate recklessly in this area, their food problem can be completely solved as long as they come out in two or three seasons. You know, in future generations, this is the granary of the world, A lot of arable land can be reclaimed, and the land here is also very fertile. If seeds are planted, it is possible to harvest in autumn without much fertilization.

Therefore, the imperial court will spend huge human and material resources and stick to Jinzhou. The biggest advantage of sticking to Jinzhou is that it can threaten the Liaohe plain at any time. As long as the slaves are built to farm, the imperial court can secretly send cavalry out to destroy and destroy their farming, so that they can't farm here and get more resources.

This is why many people believe that Jinzhou is a chicken rib and a place of little strategic significance. The Ming army must stick to it. Sun Chengzong and Yuan Chonghuan always stick to Jinzhou. That is the role. As long as Jinzhou still exists, they can threaten the whole Liaohe plain and prevent the construction and utilization of this piece of cultivated land.

Even Huang Taiji now has the same plan, that is, to quickly send an army to attack Liu Jiajun who entered the southern Liaoning Peninsula. It is best to drive them out. If they can't be driven out and destroyed, they can also stop him from farming, so that they can't be self-sufficient here, and all his food will have to be transported from Daming, It will increase their costs and increase their burden. It will certainly be unsustainable over time.

But his idea is doomed to fail, because Liu Jiajun has extremely strong shipping capacity. They can transport grain here in whole ships without fear and risk. Even the cost of grain they get is lower than the folk price, because their ocean fleet can even buy grain as far as Siam and Vietnam and then send it by sea, Its grain price is far lower than that of Daming.

Another is Huang Taiji. He doesn't know how rich Liu Jiajun is. Even when he knows it, he will marvel that Liu Jiajun can't be so rich, but Liu Bu can boast that I am really so rich.

You JianNu really think that marshal Ben captured here to manage the south of the Great Wall, but you are completely wrong this time. I just want to turn this place into a flesh and blood mill and a military training ground.

Liu Bu always had an idea that he came here to prevent JianNu from entering the Central Plains. This is also a matter of changing history. He still has some doubts about whether he can change history, but there is one thing he can do, that is, his Liu family army can no longer fight the roving bandits. The roving bandits are just a domestic contradiction, He wanted to fight JianNu. Even if he died with JianNu, it would be good for the later Han people.

It's not nice to say that even if the rogue invaders broke through Beijing and established a new Dashun imperial dynasty, he is also a Han Dynasty after all. The sons of the Han Dynasty can continue here, but if JianNu gets it, this is another different result. Therefore, he would rather spend his army against JianNu than fight the rogue invaders.

Let the imperial court send sun chuanting, Hong Chengshou, Lu Xiangsheng and others to fight the current roving bandits?

On the same day, mizhu and his men immediately led their troops south after delivering a good report to Denglai. Sure enough, when they led their troops south, they also easily captured Fuzhou and Jinzhou. There were not many JianNu soldiers here. As soon as their army arrived, the other party raised its flag and surrendered.

Because Liu Bu now learned the skill of building slaves, that is, before attacking the two prefectures, he ordered the soldiers to shoot countless arrow books with bows and arrows into the city, that is, he made an oath that if they surrendered, they would make no mistakes. If they dared to resist the king of the Ming Dynasty, chickens and dogs would not stay on the day of the city's destruction. In short, he wanted to kill the city. None of the building slaves would stay, and all of them would be killed, These people saw the great momentum of the Ming army, defeated their main force and captured their two main generals alive. In this case, they simply could not resist the Ming army, so they wisely chose to surrender.

After the two slave building armies announced their surrender, the Ming army officially controlled the Sanwei in southern Liaoning.

Of course, southern Liaoning is a relatively large place. Sanwei can only be said to be his relatively huge city. He controls Sanwei, and it is impossible to say that he controls the whole southern Liaoning, but they control these places. In addition, they have Liu Jiajun to cruise at sea. They can really say that they have completed their control over southern Liaoning.

Instead of sending troops to attack Haizhou and become a complete general army in southern Liaoning, as everyone imagined, Liu Bu and his team will wipe out JianNu in some castles in other parts of southern Liaoning and completely wipe them out. Liu Bu is ready to turn this place into a main battlefield and a place to fight JianNu. There will be no JianNu left here, Just as they treated the Han people, they all killed or became slaves. It is impossible for them to rely on these small castles and towns here or escape into the mountains to fight the Ming army. Liu Bu can't leave these future troubles. You know, these small forces can't pose any threat to him now and can't do anything to him, However, if the other side is fighting between the two armies, he can sneak into the food channels of the Ming army and inquire about their intelligence, causing a lot of trouble. Liu Bu knows what the Anti Japanese war behind the enemy is and how powerful this tactic is. He must first settle in and suppress the outside world.
