Li Fei's reform also attracted a person's dissatisfaction, that is, Du Fu.

As a great poet, after decades of reading the books of sages, Du Fu was very loyal to the Tang Dynasty court. He used to complain about Li Fei's behavior that seemed to be self-respecting. This time, Li Fei's reform was almost equivalent to separating Andong from the Tang Dynasty and forming an independent kingdom. He was very unsighted and found Li Fei directly in front of Li Fei several times, wanting to resign from the Li Fei's Protectorate Office and leave Andong and return to the Central Plains to express his dissatisfaction.

Du Fu is a talent for doing practical things and has certain talents. How could Li Fei let him leave easily?

"Brother Du, you see that the anti-army still occupies Hebei. It will take some time for the imperial court to wipe out the anti-army in Hebei. At least you can't return to the Central Plains during this period. It's better to continue working in my Andong. Don't think about other things. As long as you think, everything you do is for the happiness of the people, it's enough. I promised Brother Du that only Brother Du is in Andong, and I, Li Fei, will never learn from An Lushan's way of rebellion to bring disaster to the people of the world. How about it!" Li Fei finally promised.

"What you said is true!" Du Fu stared at Li Fei with a sharp look. Li Fei's last promise was the only reason to persuade Du Fu to continue to stay.

"Of course I won't lie to you," Li Fei nodded and made a solemn promise.

"Okay, I will stay and never leave Anton!" Du Fu was moved. He believed that as long as the words said from Li Fei were not lying. He wanted to supervise Li Fei and not let Li Fei rebel like An Lushan, causing disasters to bring disaster to the people.

In the end, Du Fu reluctantly agreed to stay, and Li Fei asked Du Fu to continue to preside over the construction of water conservancy and open up more fertile fields.

Speaking of fertile land, Anton now has a population of more than 7 million. Although Anton exports many monopoly products and is not short of money, it can buy a large amount of food from outside. However, food is related to strategy after all, and it is best to be self-sufficient. Therefore, Anton still needs more fertile land.

The best arable land north of Shanhaiguan is from the Liaohe River to the north to the Northeast Plain in the Songhua River Basin. If the entire Northeast Plain can be opened up, even if the grain output is far inferior to that of later generations, it can at least feed more than 20 million people by itself.

At this moment, Li Fei, the Northeast Plain, only opened up the Liaohe River Basin Plain in Andong and part of the original Khitan. The wider Songhua River Basin Plain is still in the hands of the Uluo tribe and Shiwei tribes. Li Fei is preparing to send troops to make a strategy.

In April, taking advantage of the weather slowly getting warmer, Li Fei ordered Zhang to lead the Fourth Army to garrison Fuyu City, expel or conquer the Uluo tribe and Shiwei tribes to the north, and incorporate the Songhua River Plain into Andong for development.

The Uro tribes had a population of about 150,000 and more than 30,000 cavalry. The Wei and Shi were divided into five parts, with a population of about 170,000 and more than 40,000 young and strong troops.

Although the Fourth Army that Zhang said had only 20,000 people, it was well-equipped, well-trained soldiers, and had comprehensive strength to defeat the Uluo tribe and Shiwei tribes. Moreover, the Fourth Army did not attack the Uluo tribe and Shiwei tribes at the same time, but defeated them one by one, and it would not be a problem to attack the Songhua River Basin.

First of all, the Uro tribe.

After Zhang Shuo led the Fourth Army to 20,000 to Fuyu City, he immediately launched an attack on the Uro territory on the north and west of Fuyu City.

The Fourth Army consisted of 5,000 Andong Iron Cavalry and 15,000 Modao Army. Each soldier was armed to the teeth, and each soldier had a rich war experience.

As a nomadic tribe, the Uro tribe made a living by grazing and hunting. The Uro cavalry has the characteristics of a nomadic cavalry. Unfortunately, the Anton soldiers of the Fourth Army were also fierce. Faced with the attack of the Fourth Army, they not only could not resist, but could not even cause much casualties to the Fourth Army.

"Kill!" Five thousand Andong Iron Cavalry rushed directly into the Uluo cavalry several times their own. The sharp horse spear kept piercing the Uluo cavalry's body and knocked them down.

The Uro Cavalry's scimitar also slashed the Anton Iron Knight soldiers, but the Uro people had poor smelting skills and the scimitars created were no more powerful than bronzes. Unless they used their best efforts, they would not be able to cut through the steel armor on the Anton Iron Knight soldiers.

"Damn it!" Anton Iron Cavalry soldier was slashed in the back by the Uro cavalry. Although he was not injured, he also furious. He held the horse spear in his left hand, pulled out the horizontal sword from his waist with his right hand, and slashed hard at the Uro cavalry.

The Uro cavalry saw him hit the Anton Iron Cavalry soldier, but the Anton Iron Cavalry soldier seemed to be unable to kill him, and no blood was splashed out, which shocked him. When the Anton Iron Cavalry soldier drew a horizontal knife and slashed him at him, he subconsciously used his own scimitar to block it.

"Ding! Puff!" The scimitar was directly cut off, and a ferocious blood mark was cut out from his chest.

The Uro cavalry stared at her eyes in disbelief, her body fell from a horse, and she died with her eyes open.

The 15,000 Modao Army was also divided into three legions, attacking and surrounding the Uluo Cavalry. The Uluo Cavalry who stood in front of the Modao Army were either shot and killed by the Divine Arm Crossbow Rain or chopped into two pieces by the Modao Army.

The Uro cavalry were killed every moment. Although the battle was just beginning, the corpses of the Uro cavalry were already everywhere on the battlefield.

"Boom! Boom! Boom!" Some Anton Iron Knight soldiers threw out shocking thunder, and some thunder bombs were also thrown out in the Modao Formation, constantly exploding.

The Uro cavalry sat down and neighed, running wildly.

After only one stick of incense, more than 30,000 Uro cavalry collapsed completely.

"Kill--" The soldiers of the Fourth Army took the opportunity to chase and kill.

After a whole day of pursuit, Zhang Shuo led the Fourth Army to kill more than 26,000 Uluo cavalry prisoners, and only a thousand casualties were more than one thousand. He won the first battle!

Although the Ulu cavalry fled more than 8,000 people, it was no longer a big deal. Zhang Shuo ordered the Fourth Army to sweep the Uluo territory in four groups in units of regiments.

On April 13, the leader of the Uluo tribe led the remaining more than 1,000 remaining troops to flee westward. After crossing the Daxinganling Mountains, he fled into the territory of the Uighurs in the grasslands in the northern desert. He thought he was preparing to ask for help from the Uighurs.

Zhang Shuo and the Fourth Army easily drank Ma Songhua River, occupied all the territory of the Uluo tribe, and captured more than 100,000 Uluo people.

"Okay, Zhang said it's good, and the Uluo tribe will be dealt with so soon." As the news of the victory reached Liaoyang City, Li Fei was overjoyed and ordered the recruitment of tens of thousands of young and strong people to build Songyuan City by the Songhua River and Baicheng at the connection between the Daxinganling and the Mobei grassland. After the two cities are built, they can firmly control the plains south of the Songhua River. In the future, based on the two cities, they will continue to go north to attack the Shiwei tribes north of the Songhua River, and completely control the entire Songhua River basin plains.

The northern strategy went smoothly. It was only a matter of time to defeat Shi Wei Zhumen and seize the entire Songhua River Basin Plain. Li Fei not only aimed at the north, but also at the Khitan and Xi tribes to the west.

As intelligence was constantly transmitted back from the Khitan and the Xi tribe, Li Fei's opportunity came.
