When Roll led the army from "Hunting Ground City" to return to the main nest "Qingqiu City", according to the protagonist's order, he left a flying knight unit stationed in "Waterfront City" to monitor the movements of the Northern Expeditionary Army on the north bank of the Great River.

In the past, "Waterfront City" also had a team of flying knights stationed there. However, as the war became tighter, they gathered a large army and temporarily moved to the "Hunting Ground City".

Due to the adjustment of the command system of the Flying Knight Legion of the Missing Dragonfly Eagle, the new Flying Knight unit in "Waterfront City" is commanded by the Locust Jackal, and the establishment is only ten Flying Knight and their fly mounts.

Previously, due to the fierce fighting in the Northeast Battlefield, the Flying Knights focused on the Northeast Battlefield and the vicinity of the Main Nest, and they had not flown across the Great River to reconnoiter the north bank for a while.

But it doesn't matter, anyway, the Northern Expeditionary Army can't cross the river.

Due to the changes on the south bank of the river, although "Dongyang Castle" has already made a rope bridge to replace, the protagonist has no plans to repair the rope bridge for the time being. Now the river is its own natural barrier, blocking the Northern Expeditionary Army that is at odds with him.

Due to the rebellion of the Great Banyan Tree, the protagonist's original planned foothold on the north bank of the Great River, the "bridgehead", has fallen to the enemy. The original plan to cut off cross-strait news and stabilize the Northern Expeditionary Army also came to naught.

Before the battle in the Northeast Battlefield, the reconnaissance of the Flying Knights had already discovered that the Northern Expeditionary Army had mobilized the main force to the "bridgehead".

If it weren't for the broken rope bridge and the obstruction of the river, the "Waterfront City" would inevitably face an attack from the north bank of the river.

Now, the protagonist needs to concentrate on all the old territories of the big-headed ant kingdom on the south bank of the Great River under his command, following the elimination of the old-fashioned king forces and the Western Alliance, the Divine Envoy King Legion and the Queen Ant inheritance faction are also frequently rubbing off, and another big war is imminent.

At this time, the protagonist naturally does not want any variables.

However, after the flying knights of "Linshui City" resumed their routine reconnaissance of Hebei, they found that there were changes in the Northern Expeditionary Army and the Paving Ant Barbarian Country.

- I'm the dividing line -

The first time the locust jackals led a team across the river, and when they circled low, they noticed an anomaly - there were too few ants moving outside the "bridgehead" nest.

The size of a nest can be estimated by the number of ants that move outside, and generally speaking, the number of ants that move outside accounts for about one-tenth of the nest population.

If this ratio is lower, then the food in this nest will not be able to make ends meet, and it will not be a long-term solution.

Anything higher than this ratio will affect the construction and repair of the nest, the care of larvae and pupae and eggs, and the daily rest of ants.

When the main force of the Northern Expeditionary Army gathered in the "bridgehead", this military base was greatly expanded and built into one of the largest giant cities on the north bank of the Northern Expeditionary Army. At its peak, the Northern Expeditionary Army stationed tens of thousands of soldiers here.

In order to maintain food consumption, a large number of ants have to go out to hunt and gather every day. Fortunately, the land along the river is fertile, the vegetation is verdant, and there are many insects, so the Northern Expeditionary Army can not only solve the garrison's military rations by foraging, but also feed back to other auxiliary nests.

But now, the density of ants seen by the locust jackals is not even one-tenth of what it used to be.

There is only one explanation, and that is that the Northern Expeditionary Army transferred the main forces away.

Although the Northern Expeditionary Army was stationed in the "Bridgehead" before and did not threaten the protagonist, this is the closest place to the evil Divine Messenger King.

After learning from the Great Banyan about the protagonist's sinister intentions towards the King's Conference and the Main Nest, the Northern Expeditionary Army completely stood on the opposite side of the Divine Envoy King's legion, and even the King of Public Security, the Senior Brother, who was close to the protagonist, also drew a line with him.

For this reason, the Northern Expeditionary Army no longer even attacked the Paving Ant Barbarian Country, but stationed the main force in the "bridgehead", waiting for an opportunity to cross the river.

Bizarrely, the Paving Ant Barbarians seem to be quite cooperative with the Northern Expeditionary Army, not only did they not launch a counteroffensive in the winter that was most favorable to them, but even after the beginning of spring, they did not gather forces to attack the territory of the Northern Expeditionary Army, and seemed to have abandoned the few nests that were captured.

Now, the Northern Expeditionary Army has actually left! Could it be that the paving ant barbarian army has come over?

- I'm the dividing line -

The protagonist is also surprised to receive information from the locust jackal, but in the absence of more information to analyze, he is also confused, so he can only order the flying knight to expand the reconnaissance area on the north bank of the river.

A day later, the latest information arrived, and the main force of the Northern Expeditionary Army was indeed fighting against the Paving Ant Barbarian Army.

However, to the protagonist's surprise, the Northern Expeditionary Army is not struggling to resist the onslaught of the Paving Ant Barbarian Army, but is taking the initiative to attack, and has already occupied several new secondary nests of the Paving Ant Barbarian.

Judging from the reconnaissance, the Northern Expeditionary Army took the initiative to attack and marched to the hinterland of the Paving Ant Barbarian Country in the northwest, aiming directly at the nest of the Paving Ant Barbarian State in the south.

Different from the two-level ruling system of "main nest - secondary nest" of the big-headed ant kingdom, the paving ant barbarian kingdom with a wider territory is a three-level ruling system of "main nest-sub-nest - secondary nest".

The sub-nest is the largest nest in a large area of the kingdom, with a large number of ant populations, and even a large male ant meeting, which usually has the power to directly command the secondary nest in the area.

Each nest is equal to each other, and has no right to interfere with the rule of other regions, and only obeys the orders of the main nest.

The split nest is the ruling core of the region and the backup of the main nest. If the protagonist is reincarnated in the Paving Ant Barbarian Country, even if the main nest of the Paving Ant Barbarian Country is raided and conquered by the protagonist like "Qingqiu City", it is impossible for him to quickly control the entire north bank of the Great River, and each branch nest will replace the function of the main nest in turn, and the protagonist can only uproot all the branch nests little by little in order to achieve the goal.

The nests of the Paving Ant Barbarians are generally stationed with a large number of troops to deal with regional wars. For example, the southern expedition every winter is undertaken independently by the southern region.

Now, the Northern Expeditionary Army actually wants to attack a branch nest with only tens of thousands of soldiers, which is extremely unexpected by the protagonist. You must know that the territory and ant mouth ruled by the southern part of the Paving Ant Barbarian Kingdom are comparable to the entire Big-headed Ant Kingdom!

But what is even more unexpected for the protagonist is that the paving ant barbarian army is almost defenseless, according to the battle situation sent back by the flying knight, the secondary nests of each paving ant barbarian country are fighting on their own, and the number of troops is so small that they are unable to fight in the field, and they are all trapped underground.

Last autumn, the Paving Ant Barbarian Army also assembled troops to launch a small-scale counteroffensive, and at one point wanted to drive the Northern Expeditionary Army down the river.

Now, this army is gone, and the Northern Expeditionary Army is only three secondary nests away from the southern nest of the Paving Ant Barbarian Country, and it can be reached in two days after marching with all its might.

But until now, after the Flying Knights expanded their reconnaissance to the southern nest, there was still no sign of the Paving Ant Barbarian Army assembling to block or counterattack.

The number of paving ants on the ground of the southern nest is scarce, and it is not at all obvious that there are a large number of ants......

In addition to the anomalies within the Paving Ant Barbarian Country, the protagonist is also vigilant to see that the Northern Expeditionary Army has made great progress in tactics!
