This nest chamber, which serves as a preset battlefield, is designed to be very narrow and long, about three or four decimeters long, and only accommodates two or three mysterious ants side by side in width.

This nest is long enough for the ballista to fire any ammunition that can easily hit the side where the mysterious ants come in, and still maintain enough lethality.

If the mysterious ants want to break through this line of defense, they must fill it with their lives.

Considering that it is not easy for countless mysterious ants to get out of the long and narrow passages and enter the battlefield, and then they are confronted with ballista stone shells like a fierce wind and rain, which are bound to suffer heavy casualties.

And as the corpses pile up, the actions of the mysterious ants will only become more and more affected.

And even if you are lucky enough to rush over, there are covering troops next to the ballista, and they will desperately cover the ballista to be transferred to the new preset battlefield in time.

If the mysterious ants dare to continue their attack, one battlefield of death awaits them.

This scene is quite similar to the tower defense game that the protagonist played in his previous life, where a group of NPC monsters follow a crooked path, constantly encountering attacks, and finally being wiped out before they reach the point.

With targeted defensive positions in mind, the more the protagonist thinks about it, the more confident he becomes, and the rich experience of tower defense in his previous life makes him feel that his design is enough to make any mysterious ant army besieging the city go to nothing.

After designing the blueprints for the defenses, the protagonist gives them to the worker ants and puts them in charge of the construction.

Since the main structure of the [bridgehead] has already been completed before, and the ant mound was basically completed last night, it is not easy to rebuild it now.

Fortunately, the most difficult part of the underground defense is mainly used in winter, and it is still too late to start construction.

If the mysterious ants appear and attack in the near future, they will have to rely on protective nets, fortifications, and ballistas on the ground to defend themselves. And the legion of the Divine Envoy King stationed here is not vegetarian.

- I'm the dividing line -

Construction is in full swing in [Bridgehead], and the protagonist arrives at the warehouse at this time.

Here, the mysterious orb in the body of the mysterious ant captured in the battle last night was quietly stored, mixed with a pile of debris, and did not seem to be particularly valued.

Yesterday, after seizing the orb, the protagonist attempts to smash open one of the oval orbs, but it causes an explosion that causes the Praetorian Guard to suffer heavy losses.

However, this explosion convinces the protagonist that these orbs are definitely of great origin, and a part of the troops escorts the remaining orbs to the [bridgehead] and places them in this warehouse.

Just now, the protagonist has always felt that he has missed something, although the protagonist is often busy, which is a common thing after the crossing, but the protagonist rarely has this feeling that he feels that something is important but can't remember.

Wandering around the lair until they reach the warehouse, the protagonist remembers the mystery ball.

The orb seems to have a magical power that makes people forget about its existence, and if it weren't for the protagonist standing in front of them, the ball would not even attract the attention of the worker ants who come and go.

The ants that placed the mystery balls also seem to have been affected, otherwise the protagonist had specially explained that he would have to escort and place these mystery balls, and his warrior would not have been able to pile them up so casually, and he would not have reported back to himself.

This ability of the Mystic Ball seems to be similar to that of parasites, which can also make ordinary ants ignore their existence, and only male ants and trained worker ants have some resistance.

Looking at these mysterious balls, the protagonist asks the worker ants passing by to dig them out and prepare to study them again.

The dangerous exploding oval balls are still the same as when they were first dug out of the ant's body, while the smaller balls are slightly smaller and the protagonist finds them darker.

This is not due to the illusion caused by the light of the underground fluorescent bacteria, the two mysterious balls, the oval and the perfect round mysterious balls were originally exactly the same color, but now there is a significant difference visible to the naked eye, which is seen under the same light source, it cannot be the cause of light.

It seems that the two mysterious balls are not the same, and perhaps the internal structure is not the same. Will the oval mystery ball explode? Will the round mystery ball explode?

The protagonist is not sure, and he doesn't dare to take another risk, in the current underground narrow space, if he causes another explosion, he won't have time to hide, and he won't have the good luck of last time.

The protagonist asks the worker ants to fiddle with the mysterious ball of the perfect circle over and over again, without seeing any clues, it is a perfect circle with a dull black-brown ball, with a broken "thread".

At this time, a worker ant in charge of fiddling with the mystery ball suddenly raised its head, raised its antennae, and opened its jaws wide, making a highly vigilant appearance.

Her unusual behavior also caused a chain reaction among the other worker ants, who nervously looked around and groped with their tentacles to see where there was danger.

The protagonist has good eyesight, and he looks around and doesn't notice anything unusual. But the performance of worker ants does not seem to be fake, and ordinary ants do not lie at all.

So the suspicious protagonist called the worker ant over and asked her.

The worker ants said that their antennae received signals from alien ants, so they immediately became vigilant.

Signals of alien ants?

The protagonist's heart moves, and he looks at the mystery ball, which the worker ant has just fiddled with with with its antennae.

The protagonist also puts the tentacles on it, but the mystery ball is as usual, and the protagonist doesn't receive any information from the tentacles, just like putting the tentacles on a rock.

And just now, it was not only that one worker ant whose antennae touched the mysterious ball, all the worker ants would touch the object with their antennae when they fiddled with the object, and no other worker ant had abnormal behavior.

Could it be that the worker ant is nervous?

But the protagonist hasn't heard of any ants with mental problems, especially worker ants and soldier ants, who have a low level of intelligence, and it is estimated that it is not the minimum intelligence threshold for mental illness...

The protagonist doesn't care, and motions for a worker ant to continue fiddling with the mystery ball, although there is no clue from the appearance, but the protagonist wants to try again.

As a result, after a while, another worker ant suddenly became vigilant, looking like a great enemy.

The protagonist's heart moved, and when he asked, he replied in the same way, and the worker ant said that he had received information from ants of other races.

The protagonist looks at the mysterious ball and makes contact with the tentacles, but there is still no response.

Do you have to wait? The protagonist simply learns to fiddle with the mystery ball over and over again like a worker ant.

Suddenly, a message appears out of thin air in the protagonist's mind, which is coming from the tentacles.

The protagonist looks closely, and one of his tentacles just touches the "thread" where the mysterious ball is disconnected, and it turns out that there is a USB-like connection!

The message that the protagonist receives in his mind is simple: "Destruction... Ants..."
