For this invasion of the Liuwa Kingdom, Su Yi felt very annoyed, originally after seizing the sixteen states in the southeast, according to Su Yi's plan, the next step would be to start against the other four major military regions of the Han Kingdom, and strive to control the entire Han Kingdom as soon as possible, and complete the task of controlling the Han Kingdom within five years.

However, Su Yi has not yet completed the integration of more than two million troops in the original Southeast Military Region, and in the Liuwa Kingdom in the north of the Han Kingdom, he sent troops to invade the northwest and northeast of the Han Kingdom, and there are two Peta Kingdoms and Voto Kingdoms in the second echelon, which also participated in this invasion of the Han Kingdom, which made Su Yi's previous plan impossible to implement.

When the Great Han Kingdom was facing the invasion of foreign enemies, if Su Yi dared to take the opportunity to attack the other four major military regions, it would definitely arouse the indignation of all the soldiers and civilians of the Great Han Kingdom, which forced Su Yi to abandon the original plan and start thinking about going north to resist the invasion of the Liuwa Kingdom.

On the afternoon of January 25, 1673 in the Han calendar, in a small building of the Southeast Military Region Headquarters in Zhengtaicheng, the capital of Zizhou Prefecture of the Han Kingdom, Su Yi was discussing with Xu Dongke, the new chief of staff of the Southeast Military Region, about the mobilization of the Southeast Military Region to the north.

Su Yi asked Xu Dongke in a deep voice: "How is the integration of the various army units of the Southeast Military Region going?" ”

Xu Dongke then said: "Marshal, according to the reorganization plan we formulated before, the army units of the Southeast Military Region will have ten armored tank divisions, twenty mechanized infantry divisions and one hundred and forty light infantry divisions. ”

In the army establishment of the Han Kingdom, there was originally only an armored tank brigade, and now Su Yi expanded the armored tank brigade into an armored tank division, each armored tank division has three armored regiments, three armored infantry regiments, an artillery regiment, an air defense regiment and a division headquarters, and the division headquarters has reconnaissance battalions, anti-tank missile battalions, repair battalions, transport battalions, etc., the total strength of each armored tank division is about 25,000 people, which is the same as the strength of the mechanized infantry division, and the entire armored tank division has almost 400 main battle tanks. Basically, they are all Type 69 main battle tanks and M60 main battle tanks produced by the system.

The newly reorganized mechanized infantry division and light infantry division of the Southeast Military Region are the same as the army of the Han Kingdom, with a strength of 25,000 mechanized infantry divisions, equipped with a small number of tanks, a large number of armored vehicles, and self-propelled howitzers, and a light infantry division with a strength of 20,000 people, which is not equipped with tanks, but is equipped with many armored vehicles, self-propelled howitzers, and a large number of cannon howitzers.

According to the reorganization plan drawn up by Su Yi and Xu Dongke, the total strength of the army units of the Southeast Military Region will reach 3.55 million, of which the number of army-type combat clones and army-type primary combat biochemical personnel will exceed 1.2 million, and more than 2.3 million officers and men of the former Southeast Military Region will be incorporated under Su Yi's command.

Now Su Yi can buy 40,000 army-type combat clones and 160,000 army-type primary combat biochemical people from the system every month, and if necessary, Su Yi can add another ten light infantry divisions to the Southeast Military Region every month.

Xu Dongke then introduced to Su Yi: "At present, our Southeast Military Region also has 16 air divisions under its jurisdiction, with more than 800 F-16 fighters and more than 800 F-15 fighters, and the navy has 13 aircraft carrier fleets. ”

In the system's goods warehouse, there are also 990 F-14A fighters, 990 F/A-18C Hornet fighters, 800 F-16 fighters and 800 F-15 fighters, as well as 16 aircraft carriers, 32 missile cruisers, 64 attack submarines, 64 missile destroyers, and 64 integrated supply ships.

Since the strength of the air force and navy of the Southeast Military Region far exceeds that of other forces in the Han Kingdom, Su Yi has not allocated these fighters and warships in the system goods warehouse to the air force and navy of the Southeast Military Region for the time being.

Su Yi pondered for a while and said: "Although the various divisions of the army have not yet completed the reorganization, but this time the Liuwa Kingdom invaded the northwest and northeast, and our Southeast Military Region must send troops, which is a matter of national righteousness, as for the battle plan for the other four major military regions, it can only be temporarily canceled." ”

Xu Dongke nodded and asked, "Marshal, how many army units are you going to send to the battlefields in the northwest and northeast?" ”

Su Yi said: "First of all, four armored tank divisions, six mechanized infantry divisions, and 30 light infantry divisions will be dispatched as the first batch of troops to support the northwest and northeast, and as for the air force, we must wait for the first batch of support troops to enter the northwest and northeast regions and establish our own field airfields, and then enter the northwest and northeast. ”

"Marshal, then I will dispatch four armored tank divisions, six mechanized infantry divisions, and thirty light infantry divisions to the northwest and northeast as soon as possible according to your wishes! By the way, Dashuai, do you accept Liu Jiarui's appointment of you as the governor of the southeast? ”

Su Yi sneered and said: "Liu Jiarui usurped the throne and rebelled to ascend the throne of the king of the Han Kingdom, if I accept his appointment, I will also recognize the legitimacy of his succession to the throne, although I will send troops to the northwest and northeast to resist the invasion of the Liuwa Kingdom, but I will not have any compromise with Liu Jiarui." ”

After the Tianjing Military Region under the control of the new king Liu Jiarui, the Southeast Military Region controlled by Su Yi also announced on January 26 that it would send reinforcements consisting of four armored tank divisions, six mechanized infantry divisions, and 30 light infantry divisions to the northwest and northeast regions to join the battlefield against the Liuwa army.

In addition, the Southeast Military Region will also dispatch more than 1,000 fourth-generation fighters from 10 air divisions to the northwest and northeast, and at the same time, a number of aircraft carrier fleets subordinate to the Southeast Military Region will also sail to the coast of the northeast region to protect the maritime frontiers of the Han Kingdom.

Not long after the Southeast Military Region made its statement, the Southwest Military Region, one of the five major military regions of the Han Kingdom, also announced that it would organize an army unit to rush to the northwest and northeast to participate in the battle against the Liuwa army.

However, the Southwest Military Region, like Su Yi's Southeast Military Region, did not directly owe allegiance to the new king Liu Jiarui, and still did not rejoin the sequence of the Han National Defense Army.

Although the new king Liu Jiarui was very dissatisfied with the fact that the Southeast Military Region and the Southwest Military Region did not take refuge in him, in the face of the invasion of the Liuwa Kingdom, Liu Jiarui also did not care about the outside world and must first settle down, and sent many telegrams to Su Yi in succession, hoping that the ten air divisions of the Southeast Military Region could enter some military airfields of the Northwest Military Region and the Northeast Military Region first.

Since the four air divisions of the Northwest Military Region and the Northeast Military Region suffered a surprise attack by the air forces of Peta, Voto, and Liuwa at the very beginning of the war and suffered total losses, the current front in the northwest and northeast can only count on the seven air divisions of the Tianjing Military Region in terms of air force.

Two of the seven air divisions of the Tianjing Military Region are equipped with fourth-generation fighters, and the remaining five air divisions are all equipped with third-generation fighters, while the air forces of Peta, Voto, and Liuwa together have mobilized more than 500 fourth-generation fighters, more than 1,500 third-generation fighters, and more than 600 second-generation fighters.

In the battle with the air forces of Peta, Voto, and Liuwa, the seven air divisions of the Tianjing Military Region suffered very heavy losses, and King Liu Jiarui desperately hoped that the air force under Su Yi could enter the battlefield in the northwest and northeast regions to relieve the pressure on the seven air divisions of the Tianjing Military Region.

Su Yi didn't trust Liu Jiarui, and it was impossible to directly send only the thousands of fourth-generation fighters under his command to the northwest and northeast alone, but Su Yi quickly sent five aircraft carrier fleets to the coast of the northeast region.

The five Kitty Hawk-class aircraft carriers in the five aircraft carrier fleets also have more than 200 fourth-generation fighters that serve as carrier-based aircraft, which can provide a certain degree of air support for the Han Army units close to the coastal areas.

The Kingdom of Peta and the Kingdom of Voto both have a number of aircraft carrier formations, but the aircraft carrier formations of these two countries did not leave their military ports and rushed to the waters of the Han Kingdom, and the naval strength of the Liuwa Kingdom was too weak, so the five aircraft carrier fleets belonging to the Southeast Military Region came to Ruian Port, the largest port on the coast of the northeast region of the Han Kingdom, without any waves.

Although Ruian Port is a civilian port, the Dahan Navy also stationed a small fleet in Ruian Port, with only a few gunboats and a dozen torpedo boats.

Zhao Tianxu, the commander of this small fleet, couldn't help but say with emotion after meeting Guan Yongchang, commander of the third aircraft carrier fleet of the Han Navy: "General Guan, I am relieved that you are here, and now in the entire Ruian Port and Ruian City, there is only a reserve infantry division temporarily formed, and this reserve infantry division is not yet full, only less than 10,000 people, and weapons and ammunition are still very scarce. ”

Guan Yongchang is a navy-type combat clone who was appointed by Su Yi as the temporary commander-in-chief of the five aircraft carrier fleets this time.

Guan Yongchang's military rank is rear admiral, and Zhao Tianxu's military rank is only lieutenant colonel, although the small fleet under Zhao Tianxu belongs to the Northeast Military Region, but after all, it also belongs to the sequence of the Han Navy, so Zhao Tianxu can be said to be respectful to Guan Yongchang.

When Guan Yongchang heard Zhao Tianxu's words, he couldn't help frowning and asked, "Ruian City is the largest coastal city in Northeast China, why do you only have such a small number of troops?" ”

Zhao Tianxu sighed and said: "General Guan, it's not a secret, now an army unit of the Liuwa Kingdom has reached Pinglong City, which is more than 100 kilometers west of Ruian City, and the army units originally stationed in Ruian City have gone to defend Pinglong City, I have always been worried that if the Liuwa Army in Pinglong City is attacked, a part of the troops will be transferred to bypass Pinglong City and directly attack our Ruian City, only with the reserve infantry division of less than 10,000 people in Ruian City, it will not be able to hold Ruian City at all, and the few gunboats and more than a dozen torpedo boats in my hand, It doesn't play a role in guarding the city of Ryan. ”

Ruian City and Pinglong City both belong to Luozhou among the thirteen states in Northeast China, and the capital of Luozhou is Shunxin City, and Shunxin City, Ruian City and Pinglong City are arranged in a triangle.

Only the capture of Pyonglong by the troops of the Liuwa Army is equivalent to opening the passage to Sunshin City and Ruian City, and if they continue south, they can attack Sunshin City, the capital of Nakju, and to the east, they can attack Ruian Port, the largest port in the northeast region.

Guan Yongchang immediately smiled and said: "This time, a lightly armed infantry division of our Northeast Military Region also followed our five aircraft carrier fleets to Ruian Port, and I also asked Colonel Zhao to help me introduce the division commander of the reserve infantry division left in Ruian City, and discuss the matter of our 33rd Light Infantry Division of the Southeast Military Region stationed in Ruian City." ”

Zhao Tianxu said without hesitation: "General Guan, rest assured, the fighting in Pinglong City is very difficult now, and the defenders of Ruian City are insufficient, and a light infantry division of the Southeast Military Region is stationed in Ruian City, there is absolutely no problem." ”

Just as Zhao Tianxu said, the commander of the reserve infantry division who stayed in Ruian City welcomed the arrival of the five aircraft carrier fleets and a light infantry division of the Southeast Military Region, and even took the initiative to express his willingness to lead the reserve infantry division under his command and obey Guan Yongchang's orders.

In this way, the troops equal to the Southeast Military Region can easily control the largest port in the northeast region, and the army units of the Southeast Military Region can also land from Ruian Port in a steady stream and enter the vast northeast region.

On the morning of January 29, 1673, 60 F-14A fighters and 72 F/A-18C Hornet fighters that took off from five Kitty Hawk-class aircraft carriers in the port of Ruian arrived at the battlefield in Sunshin City, the capital of Nakju, and launched an air attack on the Liuwa Army that was attacking Sunshin City.

And also with the Liuwa Air Force, which heard the news, engaged in a large-scale air battle.

The Liuwa Air Force also had nearly 100 fighters participating in this air battle, but unfortunately all of them were second-generation fighters, and they were powerless to fight back in the face of the many fourth-generation fighters that served as carrier-based aircraft.

In the end, in this air battle, none of the carrier-based planes on the side of the Southeast Military Region crashed, but all the 96 second-generation fighters that participated in the battle on the side of the Liuwa Air Force were destroyed, and none of them slipped through the net.

The defenders of Shunshin City, which had been suppressed, also launched a counterattack against the Liuwa Army under the cover of more than 100 carrier-based aircraft, and recaptured all the positions they had lost before.

In this attack on Shunshin, the Liuwa Army gathered a total of ten infantry divisions, with a total strength of 200,000.

The Han Army, which guarded Shunxin City, included two light infantry divisions and four reserve infantry divisions from the Northeast Military Region, as well as one light infantry division and two reserve infantry divisions supported by the Tianjing Military Region, with a total strength of about 150,000.
