Even Lin Ziran himself guessed this possibility, otherwise why would he attack Guang'an County first, not to strike first, first kill the relatively weak Guang'an Army, and then take Hexi County down, and after stabilizing the strategic security in the north, he will turn back to deal with Xu Teng, who has strong troops.

By February, although the Southern Navy under Lin Ziran was secretive and unannounced, Du Zhikuan was already 100% sure that Lin Ziran was going to attack him.

In the face of the life-and-death crisis, Du Zhikuan did not sit still, on the one hand, he continued to strengthen the defense line of Chongguang City and send more troops, and on the other hand, he urgently sent people to Hexi County and asked Hexi County to send troops to help in the war.

What do you say, if you don't send troops again, my Guang'an County will be finished, and once my Guang'an is finished, you won't be able to run away from Hexi County!

As for Hetai County, Du Zhikuan naturally sent people over to persuade Xu Teng to send troops to Anlong County first to disrupt the current situation.

But would Xu Teng do that?

A fool would do that!

Xu Teng was happy to see Lin Ziran's army go north, smash the fortress of Guangcheng, and then move his army westward.

The fight is to be fought, but Lin Ziran has to send troops north to fight Guang'an County first, and then move west after being pinned down by the Guang'an army!

Each feudal town in Nanhai Prefecture has its own abacus.

Lin Ziran wanted to unify Nanhai Prefecture, wanted to kill Guang'an County first, and then take Hexi County through Guang'an County, completely solve the threat in the north and northwest, and then turn around and clean up Anlong County, and finally have a final decisive battle with Xu Teng.

As for Xu Teng, he also thought that Lin Ziran and Du Zhikuan would fight first, and after using Guang'an County and Hexi County to contain Lin Ziran's large number of troops, he would send troops to Anlong County, and then wave his army west into Luohai County after taking Anlong County, take Luohai City, and gain a strategic advantage in dominating Nanhai Prefecture.

Even if they arrived in Hexi County, they didn't want to send troops at the first time, Lin Ziran was not easy to provoke, they also wanted to let the Guang'an Army use Chongguangcheng to consume and contain part of Lin Ziran's troops, and then choose the opportunity to go south directly into Luohai County.

Whether it was Xu Teng's Hetai County or Hexi County, they all believed that the Guang'an Army could effectively use the Chongguangcheng fortress to contain a large number of Southern Navy troops.

With the strength of the Guang'an Army, as long as he defends the Chongguangcheng Fortress with all his might, it is not so easy for Lin Ziran to take it down, if he does not fill in tens of thousands of troops, it will take several months, and it is estimated that he will not be able to gnaw on the Chongguangcheng Fortress.

As for the Guang'an army itself, they actually have some confidence, unless Lin Ziran really dispatches hundreds of thousands of absolutely superior troops, otherwise don't want to easily take the fortress of Chongguangcheng, but if Lin Ziran really wants to dispatch so many troops, it is estimated that the troops in other directions will be extremely empty, and the other surrounding counties will definitely kill them as soon as possible.

Therefore, this situation is unlikely to occur, at least the intelligence of the Guang'an Army shows that although Lin Ziran has dispatched troops, the troops gathered outside Chongguang City are about 50,000 to 70,000 people, although it can be regarded as a heavy gathering of troops, but Du Zhikuan has not sat still, has successively gathered 30,000 main forces in Chongguang City, and more troops continue to arrive in the rear, and it is expected that by the end of the Chongguang City line, it is possible to gather 50,000 Guang'an troops.

But even if he had the confidence to hold the fortress of Chongguang City, Du Zhikuan didn't want to carry Lin Ziran to the death by himself, and let other feudal towns, especially Hexi County and Hetai County, pick up the cheap.

Therefore, when I sent people to Hexi County and Hetai County to ask for help, I said that I would be as miserable as I was, as if the fortress of Chongguangcheng would be lost tomorrow.

In addition, Ningmei County, Qingyuan County, Qiuhua County and even Anlong County, they also got the news that Lin Ziran was about to make a big move, and as before, they all chose to wait and see.

Their strength is relatively weaker, and they are destined to play a supporting role in the unification war in the South China Sea, but that does not mean that they have no other moves.

Once Lin Ziran's troops were blocked outside the fortress of Chongguangcheng, once Xu Teng sent troops to the west, and once Hexi County also joined the war, then they would not hesitate to choose Hu to send troops to attack the Liangluo region.

Even if they are weak, they are not willing to be a spectator, and they are even more unwilling to see a powerful feudal town appear and finally unify Nanhai Prefecture.

For them, the best situation is to maintain the status quo, and the counties will be independent of each other and continue to be their own king of the mountain!

In the face of these external reactions, Lin Ziran continued to unify Nanhai Prefecture by himself!

Lin Ziran didn't even have any intention of changing the battle plan, but continued to implement the northern campaign plan.

What made him so calm was because the battle plan of the General Staff Office gave him confidence.

In order to conquer the Chongguang Fortress, the General Staff Office has formulated a series of complex and huge plans, according to this plan, if everything goes well, the Chongguang Fortress can be conquered within five days, even if it encounters some difficulties, but it should not take more than ten days!

Yes, the estimated time of the Chongguangcheng Battle Plan in the Northern Campaign of the Southern Navy is only five to ten days, which is not at all the one month to three months or even longer as generally estimated by the outside world.

There was only one reason for the staff to make such a battle plan, and that was the large number of breech-loading rifled artillery of the attacking troops, especially a large number of heavy artillery units.

Just those dozens of 150-mm howitzers and dozens of 100-mm field guns.

These 150-mm howitzers are not a new commodity, although there are some technical improvements and advances in the later production, but the overall performance data of the 51-year 150mm howitzer is maintained.

But those 100-millimeter cannons are the latest products of the Nanzhou Machinery Bureau, and their range, power and accuracy are quite good.

After the introduction of rear-loading artillery technology, they directly used a large number of 100-mm front-loading rifled gun barrel technology and production line, and directly modified and designed a 100-mm steel rear-loading rifled gun, which was directly introduced into the equipment after testing by the military, and was finalized as a 52-year 100-mm cannon.

The barrel of the gun reached 30 times the caliber, the total weight of the march was only two tons, and the total combat weight was only more than one ton, and its effective firing range reached 7,500 meters.

Not to mention its weight control, and its effective firing range has reached an astonishing 7,500 meters, so that the effective firing range of this artillery directly exceeds that of the 75-mm field gun by more than 2,000 meters.

At the same time, a 100-mm caliber brings a greater power than a 75-mm field gun.

These 100-mm cannons, along with the short-barreled 150-mm howitzers, would be the main artillery for the bombardment of the Chongguang fortress.

As for those 75-mm field guns and 75-mm howitzers, which are also newly served, they are limited by the factors of slightly smaller caliber and average explosive power, and can only be used as support firepower.

Hundreds of rear-loading guns, plus dozens of large-caliber smoothbore heavy guns that are still preserved.

The commander of the artillery of the Southern Navy Command, Con Deyi, said this: Even if the Chongguangcheng fortress is a turtle shell, we can smash their turtle shell hard.
