After staying in Dengzhou for two days, Liu Bu immediately returned to the brigade University and was ready to command the battle there.

The main members of the Liu family usually live in the governor's Yamen of Dengzhou. Even the old Buddha often lives in the backyard of the governor's Yamen of Dengzhou. There is no doubt that Dengzhou is the political center here, and the Liu family has temporarily settled their families here.

Miss Kong will also live here when she comes back from her provincial mother guining and handle the backyard affairs of the Liu family as her mother.

Liu Bu quickly returned to LvDa, which was also recognized by many people. After all, everyone knows that the war will start soon, and Liu Bu is the sea god needle there. As long as Liu Bu is there, he is not afraid of problems.

Moreover, the troops of a regiment were accompanied. Since Liu Jiajun publicly executed Kong Youde and Geng Zhongming, their reputation reached the peak.

Countless people crowded into their recruitment office and scrambled to sign up for the army. Even those who could not join the army joined their production and Construction Corps.

The concept of the production and Construction Corps is a plan that Liu Bu thought of when he was in disaster relief last year. They can't settle so many victims. After all, they can't just give food and arrange work, but choose to work for relief.

After they have dispersed all these refugees, they are reorganized according to the units of a regiment. They work at the regiment level and engage in production activities. They usually plough land and mine, train in slack farming, serve the people when they enter and serve as soldiers when they leave. They are responsible for protecting local areas, traffic lines and public security.

In fact, this is no different from the previous guard station system, but it has changed its name. The difference is that these soldiers of the production and Construction Corps have free people, are not hereditary, and have salaries, money and food. Unlike the former guard station soldiers, the land is greedy for officials, and their money and food have been embezzled and become slaves to officials. They are all free people now, Be responsible for the service contract signed with the Liu family. If the contract does not expire and leave, you will face a fine.

By establishing production and Construction Corps, they have settled a large number of refugees and stable places, which is also a reason why they can recover quickly. The influx of a large number of refugees also gives them a large number of labor force. If these labor forces are not used properly, they will be a disaster. If you make good use of them, they will be a good labor force.

Moreover, many of them have received military training and have a good foundation in martial arts. These people are soldiers of the army after a little training.

Liu Jiajun is now expanding on a large scale. It is certainly impossible for him to choose thousands of people like choosing a servant and a door-to-door son-in-law at the beginning. As long as he meets the conditions for joining the army, he will make an exception.

We should know that Liu Jiajun has used a large number of muskets, and the physical requirements for using muskets are not as high as those of cold weapons. It takes at least a year or even longer to train a soldier with cold weapons, but it only takes three to six months to train a Musketeer. They are now rapidly expanding their army. Liu Jiajun is due to Liu Bu's vote in Yangzhou, They have made a lot of money, so that they have no worries at all. They just need to expand and recruit desperately. As long as there is someone, they dare to recruit.

Now even the imperial court dare not recruit people like this. Only Liu Jiajun dares to do so.

The influx of a large number of refugees from other places has caused great damage and burden to the place. Only the Liu family can accommodate these refugees and turn them into their own strength. This is unexpected for those who want to weaken the Liu family and bring down the Liu family by expelling a large number of refugees here.

Therefore, their current military strength has rapidly expanded to 50000 people, which is quite powerful enough to protect themselves in troubled times.

You know, these troops are not rubbish like the imperial army. They can be regarded as elite and compete with JianNu.

Liu Bu took a warship and returned to the brigade University. This time, Zheng zining did not set out with the army, but also handed over the command to Liu Bu, who commanded the three generals under his command.

Liu Bu did not know how to use the Navy and naval warfare, so he delegated power to three senior commanders for coordination.

On the one hand, they sent a fleet to support them. Once JianNu besieged their city, they would provide artillery support at sea, while the other fleet went up along the north of the Yalu River and swept across the Yalu River to eradicate the JianNu forces on both sides of the Strait and prevent them from moving towards North Korea, Another fleet is responsible for providing them with logistical support and transporting a large number of personnel.

Liu Bu occupied southern Liaoning, but did not take southern Liaoning as a territory to operate, because at present, it is very inappropriate to cultivate in southern Liaoning, because even if the ox is like Liu Bu, he is not 100% sure that he can hold southern Liaoning. If they can't resist the army of building slaves and the other party sweeps in, their farming here will become a marriage for others.

Moreover, Liu Jiajun's strength has increased greatly. They don't lack that money and food at all. What they have to do now is how to fight JianNu, and guarding southern Liaoning is victory.

As for food, they can continue to provide them by sea. As long as southern Liaoning is used as a base to contain JianNu and as a wound to bleed JianNu, that's all.

When Liu Jiajun raided southern Liaoning, he hit JianNu seven inches and hit their key points, so that they couldn't carry out a series of plans. Whether attacking Mongolia, going south to Daming and north to North Korea, they didn't dare to let go.

JianNu's family and business are small, so they must be very cautious in every step. They can't learn from Daming. Daming can lose a hundred times, but as long as they lose once, they will be doomed, so they dare not take risks.

In the process of JianNu's rise, all their strategies seem to be very risky, but in fact they are very conservative. They are all stable. For example, when Dongjiang town was there, they did not dare to invade the Ming Dynasty and loot the customs. After they successfully eradicated Mao Wenlong in Dongjiang Town, they dared to go south and loot the Customs on a large scale, Because they don't have any worries at all.

Now it's different. If Liu Jiajun is allowed to garrison troops in southern Liaoning, they can attack Liaoyang, their heartland at any time. If they enter the Ming Dynasty through western Liaoning or Mongolia, they can easily be copied by the Ming army and cut off their way back.

That's why Huang Taiji was so angry that he ordered to ban Qi's eight banners and horses and go south with all his strength. He must level Liu Jiajun in southern Liaoning within a few months.

The first to arrive was the white flag led by Dourgen.

Although they seized Amin's military power in Haizhou City, and jirhalang was in charge of his troops, they waited in Haizhou for a few days. They thought that the Ming army would take the initiative to attack Haizhou, because only when they captured Haizhou, they would be able to complete the control of the four guards in Southern Liaoning and achieve strategic perfection.

Who knows they were wrong. Xiao Ning, the garrison general of the Ming army, has been stationed in Gaizhou city. The army has stood still in the city, but has been strengthening urban defense.

However, they didn't wait in vain. Through interrogating the soldiers, they learned that Liu Jiajun's muskets were very powerful. The configuration of muskets reached more than 80% of the army. This is an all musketed army.

In the face of such a strong army, if they rush forward rashly, they can only die. Although the firearms of the Ming army are very pit father, any general realizes that no one can stop the gun. As long as they are hit, they must be dead.

However, JianNu also summed up many ways to deal with muskets in the long-term war with the Ming army. This is shield car.

In the extremely tragic Hunhe war, they suffered heavy casualties. Although they quickly captured Shenyang Zhongwei City, they lost a lot in the Hunhe war, so Nurhachi killed 70000 soldiers and civilians after capturing Shenyang Zhongwei city.

That is, in this war, they put away the heart of belittling Ming arms and guns. Nurhachi has repeatedly stressed that shield vehicles must be used when fighting with the Ming army.

So while they were waiting, Dourgen ordered the craftsmen and soldiers to make a large number of shield cars and giant shields to deal with the Ming army.

Seeing that the Ming army did not dare to attack Haizhou, Dourgen took the initiative to lead his white flag and directly besieged Gaizhou.

In advance, Dourgen sent a large number of detailed works to inquire, but the Ming army was very strict in this regard. He sent many detailed works to investigate the military situation, and at least half of them could not return.

Both sides inevitably sent rangers to repeatedly hunt and hunt within these tens of miles, and soldiers were killed every day.

JianNu easily captured many big cities when sweeping the land of Liao town. They can easily capture these cities because they often send spies to the city before attacking the city. As long as they attack the city, the spies in the city can easily attack the city while the defenders are not on guard, They even bribed the garrison generals of the Ming army.

But this time they couldn't use these means. Although they sent troops to inquire about the news, half of them didn't come back. With such heavy casualties, they didn't dare to send spies into the city.

They also sent envoys to lobby Gaizhou city's General Xiao Ning, hoping to persuade him to surrender to the city. Who knows, the envoys sent to lobby were beheaded by Xiao Ning on the spot and hung their heads on the city gate.

Dourgen scolded angrily. He said, "the Ming people, as a state of etiquette, don't they know what it is to fight between the two countries without cutting envoys? It is said that Ben Baylor ordered to capture Gaizhou city and kill the city for three days without leaving chickens and dogs."
