The protagonist has been very angry these days, and the object of his anger is the natives who are not restless in the southern hills.

Originally, the protagonist's expansion in the southern region went according to plan and went very smoothly.

The Divine Envoy King's Legion concentrated the forces of the three legions and easily wiped out the area around the "Southern City", destroying several tribes of scythe hunters and ants, and opening up a new territory with three outer fortresses as barriers.

The Divine Envoy King's legion even sent an expeditionary force to march all the way along the valley, eliminating some of the closer and larger scythe-hunting ant tribes and eliminating hidden dangers.

At the same time, the protagonist also captures the eggs and larvae of the coveted scythe ant hunting ants during the battle, and these eggs and larvae are immediately sent to the "Southern City" to be carefully cared for, ready to train them to become excellent scout warriors of the Divine Envoy King's army when they break the pupa and become adults.

Although the eggs and larvae were limited in number, no eggs of queens and males were found. However, the protagonist knows that ordinary occupational ants can also lay eggs, and without the interference of the queen's inhibitory hormones, some occupational ants can fully develop into fully fertile queens by giving them nutritious food.

In this way, as long as a few more males are tamed, the protagonist has the opportunity to build a colony of his own Scythe Hunters, and constantly provide the best scout warriors for the Divine Envoy Legion.

In addition, there is another piece of good news that originally made the protagonist very happy - the paving ant colony that was originally ambushed brought a big surprise to the protagonist.

These colonies of paver ants were also housed in the "Southern City", living under the watchful eye of the Divine Envoy King's legion, and gradually expanding in size.

At first, the protagonist doesn't think that the paving ants have much significance for his power expansion, and even despises this race.

In terms of combat effectiveness, paving ants are only worker ants, and their combat ability is far inferior to that of professional soldier ants of big-headed ants.

From the perspective of searching for food and engaging in agricultural work, there is no advantage that both paving ants and large-headed ants can be competent.

In such a comparison, it is calculated that in addition to their amazing fecundity, the paver ants do not have too many specialties that can be valued by the protagonist.

Keeping a paving ant colony that belongs to one's own, in the protagonist's opinion, is more of a pacifying measure for the individual wisdom of the Floating Leaf King, as well as a kind of collector's habit of his own ant race.

But gradually, the protagonist discovers in his daily contact that the paving ants still have two brushes, no wonder they can suppress a large number of other races on the north bank of the Great River, and establish a huge empire far beyond the kingdom of the big-headed ants.

Because of a chance incident, the protagonist discovers that the immunity of paver ants is very strong.

At that time, there was an ant plague in the "Southern City", and many big-headed ants, including the soldiers of the Divine Angel King's legion, were infected by the ant plague.

The patient shows weakness, mildew in the crevices of the carapace, and begins to have difficulty eating. Over time, these infected people will die of weakness.

This kind of ant plague or similar diseases occur from time to time, as long as it does not spread in a large area, in the past, the big-headed ants let the patients die.

The protagonist still has some experience in epidemic prevention when he was a human being, and all he can do is isolate the infected and send ant hands to dig quicklime to disinfect the nest and other basic measures.

However, when the protagonist inspects various parts of the "Southern City", he discovers that the infected members of the paving ant colony have quickly recovered.

It turns out that once the paver ants find out that they are infected with ant plague, they will constantly lick their outer carapace and disinfect themselves with saliva. Some healthy paver ants will also "treat" their sick counterparts in this way.

After observing it, the protagonist discovers that the saliva of the paver ant contains an ingredient that inhibits and kills the virus, but the saliva of the big-headed ant does not contain this ingredient.

Subsequently, the protagonist orders the paver ants to take care of the sick big-headed ants, and the spread of the epidemic is quickly contained.

Later, in practice, the protagonist discovers that the saliva of the paver ant is also effective for many common ant diseases, whether it is a paver ant, a big-headed ant, or a hunting sickle ant, and there is no distinction between class ants, queens, males, and larvae.

In addition to the saliva they carry, they are also good at finding plants and herbs, and know the therapeutic effects of some plants for specific diseases.

It is no wonder that as a highly fertile ant, the size of a single colony of paver ants is often tens of thousands or even hundreds of thousands, and the density of each nest is extremely high. If you don't have the ability to fight infectious diseases, you can easily be wiped out by the plague.

What's more, the ancestors of the paver ant had a more scavenging diet, they did not hunt much, but preferred to collect fresh or rotten insect carcasses for food. This lifestyle habit inevitably brings in contact with a large number of germs, which exacerbates the hidden danger of disease in this group.

In order to combat the threat of germs, paver ants gradually evolved bacteriostatic saliva and learned to use natural plant aids (many animals use natural plant minerals to cure diseases, an experience that can be passed on to future generations).

On the other hand, the hunting sickle ant and big-headed ant races, which rely on hunting, grazing, and gathering as their main food sources, do not have this racial talent, and they are less threatening to face diseases, but once encountered, they have nothing to do.

The protagonist immediately makes full use of this racial characteristic of the paving ant. In this way, the paver ant was soon given the mission of "doctor".

Not only are there a group of "Paving Ant Doctors" stationed in each nest under the protagonist's influence according to the proportion, but even the Paving Ant Medical Team is also stationed in the various Divine Envoy King Legions, the scientific research team of the Little Secretary, and the workshop of "Dongyang City".

The big-headed ant and the paver ant, the old enemies who have been fighting for thousands of years, have achieved peaceful coexistence and win-win in this way.

Opened up the territory of the south, obtained the larvae of the sickle hunting ant, and discovered the use of the paver ant. It seems that the protagonist's career in the southern hilly region is developing smoothly and his influence is expanding rapidly.

Although these indigenous scythe-hunting ants in the southern hilly areas are very strong in combat, the number of warriors of a single tribe is too small to resist the large-scale attack of the Divine Envoy King's army.

Therefore, the protagonist miscalculated the security situation in the southern region for a while, thinking that he could sit back and relax.

But at this moment, who would have thought that those indigenous tribes of sickle-hunting fierce ants who didn't know whether they were alive or dead would actually unite and gather unprecedented combat power.

This tribal alliance not only attacked the fortress garrisoned by the Divine Envoy King's legion, causing some casualties, but also seriously threatened the safety of the "Southern City".

This has actually harmed the interests of the protagonist and forced the protagonist to take action.
