Although Nanhai Prefecture has not yet been completely unified, the Liangluo region, Guang'an Hexi, and Anlong Hetai region are all under the control of the Southern Navy, and the Liangluo region is the essence of Nanhai Prefecture's industry and commerce.

Lin Ziran, who controls these areas, has enough population, financial resources, and industrial base to maintain an army of more than 200,000 or even more than 300,000 in extreme cases, and is also an army equipped with advanced weapons that can receive regular training and maintain combat capability.

With such a scale of the Southern Navy and the industrial strength behind it, Lin Ziran is confident that he will face threats from any direction, whether it is Quyang Prefecture in the north, Zhongluo Prefecture in the northwest, or Dongding Prefecture in the east, and Ningyu Prefecture in the west.

In a single-line battle, Lin Ziran has enough confidence to rely on the powerful Southern Navy to defeat any of the surrounding states.

Just like the Duke of Meng back then, he had full confidence to launch an Eastern Crusade.

But the problem now is that the South China Navy is not fighting on a single front, or even on a two-front front, but on the western front.

Even if the northwest front is among them, because the strategic value of Hexi County is not too great, plus the terrain and other willingness, it can take a strategic retreat and combine the northwest front with the northern front.

However, the current South China Navy is facing a four-front operation!

Under the four-front operation, even if others did not launch a large-scale siege, they could only fight at two ends in three days, and the southern navy would be exhausted.

In order to change this embarrassing situation, Lin Ziran ordered to hold the eastern and western fronts, strategically abandon the northwest front, and gather more than 100,000 troops to launch a large-scale counteroffensive on the northern front, trying to take down the Quyang Prefecture army first, and then end the crisis of the fourth-line operation.

The Southern Navy also did not live up to his expectations, and the Eighth Division and other troops on the Eastern Front, relying on the defense line of the Hetai Heights, blocked the attack of Yuan Yonghan's troops to the death.

The Sixth Division also put up stubborn resistance, and even took the initiative to abandon some areas, and gradually retreated, gradually killing and wounding the enemy troops, taking advantage of the fact that there was no developed inland river transportation system in the western front, and the enemy's advance could only rely on the situation of advancing on foot, exchanging space for time.

With the situation on the eastern and western fronts initially stable, the South China Navy gathered 100,000 troops to launch a super-large-scale counteroffensive against Quyang Prefecture on the northern front.

No matter what the specific results of the battle are, the southern invasion army of Quyang Prefecture is definitely going to end.

In this way, Lin Ziran also began to set his sights on the eastern and western fronts, and did not say that he would take the opportunity to continue to let the troops move north, and even cross the Luohe Gorge into the territory of Quyang Prefecture.

His request to the troops was to destroy the enemy's living forces as much as possible, and then seize the Luohe Gorge, and finally redeploy in the Luohe Gorge to stabilize the northern front.

Later, it can also appropriately transfer part of the troops to the west to reinforce Hexi County, where there is only a garrison division, a cavalry division and a regiment of deformed and weak resistance, in order to avoid large-scale losses and even carry out a large-scale active retreat, and now it has retreated to Hexi County.

However, the enemy army on the northwest front is actually just like that, there are not many troops, and there are not many heavy weapons, as long as the southern navy has a little more Hexi County, it is not necessary to say that it will launch a counteroffensive, but there is no problem in holding it.

The eastern front is similar, relying on the Hetai Heights, it is not so easy for Yuan Yonghan to kill it.

Now the biggest problem is the Western Front.

From Qingyuan County all the way east, to Luohai City, this area belongs to the plain terrain, but there are no mountains to block it, not even large rivers.

It is an area where there is no danger to defend.

Today, the defense of the Sixth Division on the Western Front is more of a continuous resistance, and the mobile defense of launching a small-scale counteroffensive when there is an opportunity does not mean relying on a solid defensive line to defend to the death.

This also led to the fact that the Sixth Division was actually very aggrieved.

Even if their own side has an absolute firepower superiority in firepower, but the number of troops is too small, and the enemy forces rely on the absolute superiority in strength to constantly carry out strategic detours, but there is no talk of colliding head-on with the powerful firepower of the Sixth Division.

Subsequently, even if a part of the troops of the Second Garrison Division were transferred to the west for reinforcements, it still did not help.

Previously, the Sixth Division had sent reports to Lin Ziran many times requesting reinforcements.

But at that time, the counteroffensive on the northern front was on the line, and Lin Ziran couldn't draw other troops at all, so he could only encourage the officers and men of the Sixth Division to show the spirit of not being afraid of hardship and sacrifice, and resisted step by step.

This resistance, in fact, to put it bluntly, allows them to make a limited retreat.

The bottom line set by Lin Ziran for the Sixth Division is actually very loose, and it is really impossible to retreat all the way to the outskirts of Luohai City.

As long as the Sixth Division can ensure the safety of Luohai City and some areas in the suburbs, ensure the safety of Luohai City and the surrounding industrial and commercial areas, and do not let the enemy destroy the many factories in Luohai City, then the task will be completed.

However, this is the bottom line, and it is a choice that is forced to be helpless in the end.

If it could, the Sixth Division still needed to keep the enemy as far away from Luohai City as possible.

But now, the 6th Division is obviously fighting very reluctantly.

It's not that the casualties were so heavy, in fact, there was no large-scale decisive battle between the two sides, and there were not many casualties on both sides.

The mode of engagement between the two sides is very special, and Ning Yuzhou's men and horses seem to know that the Sixth Division has strong firepower, so they choose a large-scale strategic detour, and at the same time dispatch a large number of cavalry to attack the logistics line of the Sixth Division and small troops.

The strategic detours of the other side caused the Sixth Division to constantly lose the strategic initiative, and the logistics line was frequently in crisis.

At the same time, a large number of small-scale mobile battles made it difficult for the Yugoslav Navy's proud artillery firepower to be brought into play, and most of the time it could only rely on rifle firepower.

When this fight started, the Sixth Division was very aggrieved.

After weighing the situation, Lin Ziran decided to go south immediately, and then reinforce the northern front.

That night, although the battle on the northern front had not yet completely ended, Lin Ziran had already begun to ask the staff to formulate a detailed follow-up battle plan.

It was planned that the First Army would stay on the northern and northwest fronts to continue the follow-up battles and ensure the safety of Guang'an and Hexi counties.

The Second Army began to gradually withdraw from the battlefield and move south by boat, and finally went to the Eastern Front to support the Sixth Division.

The next morning, the forward troops of the Second Army had successfully arrived at Luohe in a roundabout way, and the entire Second Army had already built a complete defensive line on the road of the Quyang Prefecture army's northward retreat.

Then it was announced that Yang Jun's headquarters of the Second Army of Quyang Prefecture were completely surrounded by the Southern Navy!
