The Destroyers spent most of the day on the platform on top of the mound, busily carrying corpses, destroying protective nets, and even trying to gnaw and dig through the sturdy concrete shell of the anthill.

The flying knight in the air was already tired from circling, so he found a safe branch in the linden tree and stopped to rest, and after a while he recovered before continuing to take off.

This year seems to be colder than yesterday, much colder than the previous days, and windy. Compared with the good days when it warmed up a while ago, flying in today's weather is really a great test of physical perseverance.

But now that the Flying Knights are unable to return to the [Bridgehead], the entrance and exit there are blocked by the Destroyer, and the Flying Knights have to endure the torment of continuing their mission until the enemy retreats in the evening.

By four o'clock in the afternoon, all the ant corpses outside had been emptied by the destroyers, and even the drowned destroyer corpses in the trenches had not been spared.

At this time, the protective net was almost destroyed, most of the parts fixed to the city wall were bitten off, and some of the wooden wedges that were fixed and pierced deep into the concrete of the city wall were lifted by these destroyers with brute force.

All that remained of the remnants of the protective net was the top fastened to the trunk of the linden tree, and there were still a few anchor points left at the bottom, which were in tatters swinging in the cold wind, completely defenseless, and the vicinity of the anthill was full of falling broken ropes.

It was only by this time, with the sun still more than an hour before the sun set, that the Destroyers began to assemble a small group of men and horses to attack the [bridgehead] underground lair.

The first wave to attack was only a dozen small destroyers, and in the underground defense, the outermost was a squad of the 5th Legion.

The original duty of this squad was to be on guard, and once they saw an enemy attacking, they would quickly warn them, and then retreat to the preset battlefield nest in the rear.

But the Destroyers were too few to attack, and in the main passage wide enough to pass through a large beetle, the team quickly surrounded most of the Little Destroyers, and then killed the encircled enemies at a slight cost, sparing only three Little Destroyers.

The little destroyer who retreated quickly attracted more companions, and the five big destroyers were followed by about twenty small destroyers, and they fought violently into the hole.

The front-line Divine Envoy Wang team did not hesitate to retreat under the commander's order, and at the same time sent a messenger to warn the rear.

The Great Destroyer itself isn't very fast, and it's not as agile as the smaller Bighead Ant in the twisting passages. And although the Little Destroyers are fast, I don't know why they just don't exceed the Big Destroyer, and they keep moving slowly behind the Big Destroyer.

The god made the squad of the king's legion safely retreat to the preset battlefield, and the fate of this squad could be abandoned, as long as they succeeded in warning them, it would be worth it even if the whole army was wiped out. But the slow actions of the Destroyers allowed them to avoid their doom.

On the battlefield, there will always be some troops who will be forced to die because of the overall situation. For example, the troops behind the palace when retreating, the first troops when attacking fortifications, and so on.

An iron army, in which the soldiers know that the task must be carried out resolutely and resolutely, in order to be invincible. And most armies are unable to "treat death as home".

But in the ant army, basically all the commanders and soldiers have this consciousness and can sacrifice for the sake of the collective, which is why the war in the ant world is more cruel.

When the pursuing Destroyer troops arrived at the narrow preset battlefield, they had just emerged from one end and all entered the battlefield when they encountered a salvo of two ballistas from the other end.

Such a distance is exactly the distance at which the ballista can exert its maximum power, and the battlefield is long and narrow, so the ballista does not choose to fire scattered bullets, but directly fires boulder shells.

Boulder projectiles rampaged through the ranks of the Destroyer, tossing over a long line of enemies, leaving blood and flesh everywhere.

At such close range, even the carapace of the Great Destroyer could not stop the boulder bullet from passing through, and the Destroyer who hit him head-on was shattered into a mess, and his companion behind him was also injured by the boulder bullet that pierced through his body.

With just one shot, two boulder bullets killed or injured five Destroyers, and the smaller Destroyers behind also suffered a lot of losses.

The ballista was being reloaded, and one of the remaining lightly wounded Great Destroyers with a few small Destroyers attempted to pass over the dead and badly injured corpses of their companions and kill them towards the ballista.

However, the team of the Divine Envoy King who was covering on the side quickly caught up and blocked the way to buy time for the ballistas in the rear.

When this team completed its mission and retreated, more than a dozen soldiers were killed, including the troops behind the palace.

The rewound ballista fired a volley of shotshots, killing the small group of destroyers.

Upon learning that the enemy is attacking the underground defenses, the protagonist has already left the monitoring room and gone underground.

He was not satisfied with the timely defeat in the battle he had just received. Although the defenders eliminated more than thirty enemies at the cost of a dozen warriors, the protagonist felt that there was room for improvement.

The first is that the ballista fire rate is too slow, and the gap between them is too long, requiring the defenders to sacrifice a lot of money to buy time, and this attrition is also terrible to accumulate in a long battle.

And when two ballistas are fired at the same time, judging from the on-site information package, the power is somewhat excessive. If the combat effectiveness of two ballistas fired at the same time is 100, then in fact, one ballista can reach 80, and the marginal utility of the other ballista is greatly reduced.

The protagonist immediately instructs the ballista in front of them to fire at an interval of 15 seconds during the next battle.

The reload time of a ballista is about half a minute, which increases with the fatigue time of the shooter team, but 15 seconds is basically the best solution for fire continuity.

In addition, with the preset length of the battlefield, the enemy will not be able to rush to the ballista in fifteen seconds unless he rushes with all his strength without reservation, and if it is properly coordinated, it is completely possible to delay the time without the defenders risking their lives.

The ants don't have a concept of seconds, but the males still have a sense of time, and after the protagonist describes this time as the time to suck up three drops of honeydew, the Ballista Squad Commander has learned exactly when to fire.

The Destroyer quickly organized a third wave of attack, which was about the same as the second wave and was quickly routed, but this time the defenders still sent their troops to delay the enemy for a short time, as the small Destroyer quickly approached the ballista.

This time, the defenders killed more than two dozen Destroyers at the cost of three deaths, but two Destroyers escaped.

These three waves were clearly tentative attacks by the enemy, and by this time the sun was already very close to the horizon, and the enemy would not last long even if he continued to attack.

Tomorrow is the time when the pressure on the underground defense line is the highest!
