After Liang Chenglei led the First Army to Pingnanzhou in the north, he launched military operations along the Jing River and its many tributaries, and the road was actually smooth.

Most of the main forces in Pingnan Prefecture had already been lost in the Battle of Jingzhou and the Battle of Zhenbeicheng, and the few remaining troops were simply unable to resist such a large corps of the First Army.

Bei'an Prefecture in the north has never looked like a big state, and even if it has sent troops south to assist in the battle, it has not sent many troops.

As for Gaoqing Prefecture and Ningwu Prefecture, these two states are now too busy to take care of themselves, they themselves have already suffered heavy losses in the Battle of the Southern Front of Jingzhou and the Battle of Jingshi, and in the follow-up in the northeast of Jingzhou, they will continue to face the continuous attack of the Second Army led by Ye Keming, and it is difficult to even protect themselves, and it is impossible to send troops to help.

Nanhu Prefecture in the west, they are also under great pressure, facing the threat of the Third Army in the east, and the threat of the Fourth Army along the Luo River in the west, especially the Fourth Army is on the south of the Luo River, thinking every day that they want to kill along the Luo River, in this case, they are not able to send reinforcements.

When the surrounding states are unable to protect themselves, Pingnan Prefecture can only get limited help from Bei'an Prefecture, but just with this help, how can it resist the First Army led by Liang Chenglei.

The First Army Corps led by Liang Chenglei had three corps, one cavalry corps, two heavy artillery, and a front-line combat strength of nearly 200,000 people, and a large number of heavy weapons, equipped with a large number of medium and large-caliber rear-loading artillery of 150 mm caliber, 120 mm caliber, and 100 mm caliber, and also had the fire support of various artillery fleets under the Jinghe Subfleet.

They simply can't have a head-on confrontation!

This is also the reason why the First Army was able to quickly advance and penetrate deep into the hinterland of Pingnan Prefecture after moving north.

In order to remedy their inferiority, they resorted to shrinking their forces while sending troops around the line of attack on the Imperial Army's logistics.

This caused the First Legion to suffer a certain amount of trouble, but this trouble was not fatal, at most it made the rear transportation of the First Legion more troublesome, and sent more troops to carry out armed escorts.

But even so, Liang Chenglei doesn't plan to give them too many opportunities.

This kind of harassment and resistance of the enemy army also needs to be supported by the large rear, without a solid territory in the rear, they simply cannot maintain the army, their army can not achieve the end of the territory, and can still get into the ravines and ravines to play hide and seek with the Imperial Army, they do not have the organizational ability, not to mention, and their army itself cannot be willing.

If you can fight, you will fight, and if you can't fight, you will surrender, this is the normal choice of the troops of the state and town.

Therefore, Liang Chenglei decided to adjust the battle plan, no longer to spread out the troops to try to control them in an all-round way, but to concentrate his forces, capture the state city of Pingnanzhou and several other important cities in one go, and then go all the way to Bei'an to capture their state capital and major cities.

When these medium-sized and large cities are defeated, then the local feudal regimes of Pingnan Prefecture and Beian Prefecture can basically be declared extinct.

Even the feudal regime was destroyed, so the remaining resistance was naturally gone.

When this decision was made, the First Army Corps also began to shrink its forces, and did not even care that some counties and towns in the central and southern regions were still controlled by the enemy, but directly concentrated its forces, taking each army as the main direction of attack, and at the same time marched to the state city of Pingnan Prefecture and the counties and counties.

When the First Army began to concentrate its forces, the enemy continued to harass and attack, but the First Army quickly took the major cities.

On September 18, the Fourth Army under the command of the First Army Corps captured the state city of Pingnanzhou, and the Third Army and the Seventh Army also captured the county towns of many counties in succession.

On October 2, the First Army conquered the county town of Yanqiu County in the northern part of Pingnan Prefecture, and declared the county towns of the 11 large and small counties of Pingnan Prefecture, all of which fell under the control of the Imperial Army.

Pingnan Prefecture ordered Zuo Pingshu to resist to the end and died in the battle in the city of Yanqiu County.

Immediately afterwards, the First Army did not stop its pace, but continued to go north to Pak Anju, and he wanted to take advantage of the cold winter in the north to completely take Pak Anju.

On October 4, the vanguard of the First Army Corps had entered Bei'an State, seized the fort of Ningbei County, the southern gate of Bei'an State, and opened the checkpoint leading to Bei'an State in the upper reaches of the Jing River.

Subsequently, the army, under the cover of the naval gunboat force, killed and wounded the hinterland of Bei'an.

Bei'an is located in the north, and further north is the severe cold and frozen land zone, because the geographical environment is not very good, and the climate is not good, so the population is small, and the agriculture can only be said to be average, and its own strength is weak.

Although they tried to mobilize 50,000 troops to resist stubbornly, the 50,000 troops they mobilized at the last moment did not resist stubbornly according to their wishes, but when the First Army arrived, under the leadership of senior generals, they surrendered and revolted on the spot cleanly.

Pakan State, without even putting up a decent resistance, was completely taken by the First Army, and the town of Bukan State was destroyed.

The First Army quickly moved north, and after successively capturing Pingnan Prefecture and Bei'an Prefecture, the situation of the unification war of the Daheng Empire changed dramatically.

The army and navy forces of the Lin Dynasty, relying on the Jinghe River, divided the northern states.

The remaining four prefectures, Ningwu Prefecture and Gaoqing Prefecture, as well as Nanhu Prefecture and Northwest Prefecture, basically no longer have the possibility of continuing to resist stubbornly.

This kind of general situation can be seen clearly by many people, including the feudal towns that control these areas, so the attitude of these feudal towns has also begun to soften.

At this time, Lin Ziran ordered to send an order to the above-mentioned four states that were still resisting, reiterating the preferential policy of surrendering to sincerity, and also issued a strongly worded threat for the first time during the unification war: If you don't surrender now, then you won't have a chance to surrender in the future!

This threat has shaken many people, and many generals in the four states have already begun to bypass the feudal towns above and directly contact the Imperial Army to revolt anyway.

Although the feudal towns of the four states still want to resist stubbornly, well, in fact, their resistance is not to resist reunification, in fact, they themselves know that reunification is already a contemporary trend, and they cannot resist it no matter what.

Their stubborn resistance is just hoping that through stubborn resistance, they can win some voice for themselves, so that they can win a better way out for themselves in the follow-up peace negotiations, for example, they can continue to be the state commander with actual military and political power, and continue to be a feudal town that does not listen to the tune.

But the feudal towns want to let the troops under their command continue to fight and win a better future for themselves, and the generals under their command are not stupid, and they will not be stupid to be a stepping stone for the feudal towns above.
