Although in the battle in the first two days, the Northern Expeditionary Army of the big-headed ant kingdom on the defending side, based on the geographical advantage and sufficient preparation in advance, had the advantage on the battlefield.

However, the powerful Paving Ant Barbarian Army showed no signs of being discouraged, and for the next few days, they continued to attack every day.

And as the flow of water in the stream became less and less, and the water surface became narrower and narrower, the effort paid off, and the dead branches and fallen leaves that the paving ant barbarian army threw into the stream every day finally joined together, completely covering a large section of the stream, and even the flowing water could not wash it away.

In this way, the paving ants no longer need to build pontoon bridges every day, and the big-headed ant army is unable to destroy such a huge bridge in addition to defense, and the big-headed ant army's most powerful assistant and most important moat these days is useless.

After breaking through the natural danger of the stream, the Paving Ant Barbarian Army dragged the battle into the usual ground decisive battle. After several days of unusually bloody and brutal fighting, tens of thousands of corpses were left behind on both sides.

Such heavy casualties did not make the offensive of the Paving Ant Barbarian Army hesitate or halt somewhat, but the Big-Headed Ant Army was forced to switch to the nest defense the next day - they could not afford such a high-casualty battle, even if the enemy suffered heavier losses.

From this day on, the battle of "Target Ding" turned into more brutal street fighting, although there were no large regiments fighting, but in every underground passage, nest and entrance, there were dense fighters on both sides.

In the narrow battlefield underground, no warrior was able to retreat. No matter how brave the warrior was, he was blocked by his companions behind him, and he could only keep dealing with the enemies that poured out in front of him, and finally after being exhausted, he was killed. The brave and the cowardly, the strong and the weak, will not escape the ultimate fate of death.

Even though the Big-Headed Ant Kingdom Army has an advantageous class of troops such as soldier ants that are suitable for small-scale street battles, under the offensive of the Paving Ant Barbarian Army regardless of casualties, and their tactics of digging around while attacking, the shallow underground nest is still lost.

It wasn't until night approached and the Paving Ant Barbarian Army withdrew that the Big-headed Ant Army regained its lost territory.

But the paving ant barbarian army did not "leave nothing" behind, before retreating, they dug the shallow nest full of holes, each passage and nest has countless new entrances and exits to connect to the nearby area, and the entire shallow nest was dug in all directions, so that the big-headed ant kingdom army could not use every narrow space to resist.

And the only main entrance and exit from the ground has also been expanded countless times, making it convenient for the paving ant warriors to enter and exit.

Even if the Big-Headed Ant Kingdom Army organized a team of troops to work overnight, after all, it was easy to destroy and difficult to build, and it was impossible for them to repair all the damage in one night.

Therefore, the next day, when the paving ant barbarian army, which had already warmed up in the sun, attacked again, the big-headed ant kingdom army lost the shallow nest with a faster speed and greater casualties.

Fortunately, the Big-headed Ant Kingdom Army was ready to hold on to it at the beginning, and they have been "digging deep holes and accumulating grain", and they have expanded the underground part of the "Target Ding" a lot, and built the soldiers' living rooms and granaries at the lowest level, so there is not much loss of the already scarce stored grain.

The battle continued for another week, and every day there would be a new lost area in the underground part of the "Target Ding" that the Big-headed Ant Kingdom Army was holding onto, and it was completely destroyed, making the Big-headed Ant Kingdom Army unable to repair it.

After more than half a month of fighting, the defenders of the big-headed ant kingdom have lost nearly half of their troops, and with the wounded, their combat effectiveness has dropped by more than half.

Although the Paving Ant Barbarian Army is not having a good time, in the battle to break through the stream and the underground nest, it is the attacker who needs to suffer greater losses. However, the Paving Ant Army, which has the advantage of troops and materials, can still hold on.

The Big-Headed Ant Army couldn't hold on, and even one of the only four remaining senior commanders, General King B, was killed in a defensive battle in the middle area because the command post was suddenly dug through by the enemy.

After days of controversy, the police lord and the other two kings finally reached an agreement.

In the evening of that day, not long after the withdrawal of the Paving Ant Barbarian Army, the Big-Headed Ant Kingdom Army began to retreat overnight.

Although ants are rarely active at night, this is not absolute, ants sleep for a short time and often work in the nest at night. In an emergency, going out is not a difficult task.

Twenty-nine legions were evacuated from Target D, carrying the remaining food with the corpses of both fighters, the rest of which had been largely eaten by the corpses of the soldiers on both sides, and retreated to the next lair.

At the beginning of the war, the defenders assembled at "Target D" had 60 legions, but now less than half of the fresh forces have withdrawn, which shows the intensity of the battle.

After a small midnight march, the withdrawn Big-headed Ant Kingdom Army successfully arrived at "Target C" under the bright night light, and joined the garrison left here by the previous King of Public Security A, and the strength of the army reached 30 regiments again.

The march was not without twists and turns, and the gradually decreasing temperature at night caused many soldiers to freeze, and the large army, which was already carrying a large amount of supplies, could not take these soldiers away, so they could only leave them behind, and only the male ants would be rescued. The warriors who were thrown down, in the cold night, in the night full of countless fierce insects, it was almost impossible to see the next day's sun.

But this loss was acceptable for the large forces that arrived safely at their destination.

The entire army began to frantically expand the lair overnight, especially the space on the ground floor of the lair to accommodate many warriors and supplies.

And it is a miracle that the remnants of the army who remained in the "Target Ding" held out for three days without a grain of food.

These remnants consisted of only about four legions, all of which consisted of wounded soldiers who were badly wounded, who had no food, and which was taken away by the large army. In this case, they still abandoned most of the nests under the leadership of the remaining male commander, and held on to the strongest bed of the ant king and queen, blocking the momentum of the strong attack of the paving ant barbarian army.

When there is no food, they feed themselves with the newly created corpses of both the enemy and the enemy, and when there is no water source, they drink the droplets of water condensed on the walls of the lair. This lone army was not overwhelmed by the influx of enemy troops like a black tide until the enemy dug through the walls around the last position.

Under their desperate cover, Target C's large force had a few precious days to reinforce its defenses.

This will have a significant impact on the future of the battle, as Target C does not have the Stream Danger. But the Big-Headed Ant Kingdom Army has adapted to the street fighting tactics of the Paving Ant Army, and has set out to deal with it!
