[Dongyang Castle], deep underground.

This is a large-scale nest, different from the traditional ant nest structure, not only is the area much larger, enough to be the size of a coffee table in the human world, but also the overall shape is a flat, regular oval.

In addition, in order to stabilize the ceiling, some wooden sticks were used as pillars in this nest, and the ceiling and four walls were also smoothed with clay and baked with fire, and a lot of charcoal was piled up in the corner to ensure that it was protected from moisture.

A large number of fluorescent bacteria are planted all over the four walls like no money, and although the nest is not as bright as the outside, it is also like installing LED lamps, providing enough light for the ants working inside.

Anyway, the worker ants working inside rely more on their antennae than compound eyes, and they feel that the light is bright enough now.

This is a newly built ballista workshop in [Dongyang City], where hundreds of worker ants work, and dozens of large worker ants serve as managers.

The large workers and workers were divided into arrays, some of which were responsible for processing wood with copper and stone tools, some for gluing and rope tying, some for attaching locust or grasshopper tendons, and some for making bowstrings from hemp fibers and ant silk.

Although there is no assembly line in the workshop, the production has been carried out in stages, and the efficiency has been greatly improved.

If you ignore the humble factory buildings, the dim lighting, and the ants at work, this is simply a workshop or a small factory in the human world.

Such a ballista workshop, here is the second, there is another not far away, and in another place, a third ballista workshop is under construction. At that time, the ballista production capacity of the Divine Angel King's Legion will be increased again.

Not only the ballista workshop, but also the workshop for giant arrows for ballistas, the pottery and stone shell workshop, and the slinging workshop are also nearby.

Near the combustion chamber, there are bronze casting workshops, stone tool workshops, pottery workshops, and charcoal burning workshops, which are convenient for the use of nearby fire sources.

In addition to military use, there are fermentation workshops for processing food, pickling and smoking workshops, etc.

This is the industrial center of the entire Divine Envoy King Legion, producing a large number of finished products that far exceed the technological level of this world.

In addition to production, there are also a large number of large worker ants engaged in scientific research.

Although the protagonist has been directly in [Dongyang City] for very little time, he will still specify scientific research goals from time to time, and even directly provide a plan, so that the little secretary II of the scientific research group will lead the big workers to carry out scientific research.

For example, now, the little secretary II and the others are experimenting with the flammable liquid in the mysterious ball according to the protagonist's idea.

This is a dangerous job, so the experimental site is located in the most remote part of the ground, far away from important facilities such as combustion chambers, granaries, and workshops.

Moreover, during the experiment, the large worker ants will also hide far away, and only the worker ants are responsible for operating according to the requirements of the information packet in their minds.

The experiment has been going on for more than a week as of today, and the experimental nest has collapsed four times, and dozens of worker ants have died for various reasons.

But today, the little secretary II finally got some results and hurriedly reported to the protagonist.

Previously, the protagonist has learned through reasoning that the light blue liquid in the Mystery Ball burns in the air, and that the Mystery Ball can explode when heated or spontaneously combusted, also due to the liquid inside.

Although it is impossible to analyze the composition of this light blue liquid, the protagonist is also imagining that there is a way to keep the light blue liquid after leaving the mystery ball, and it can be used more conveniently according to the amount, instead of being able to save the mystery ball one by one, which needs to be detonated in a dangerous way.

They instructed the worker ants to use a simple gravity stone hammer to smash open the mysterious ball, let the light blue liquid flow out, and then experiment with various methods to avoid the spontaneous combustion and spontaneous explosion of the light blue liquid.

Once, after the pale blue liquid came out, the ants used loose sand to absorb the liquid. Results: Failed, the sand turned pale blue began to spontaneously combust, but did not explode.

Another time, the charcoal particle adsorption was switched, and it was found that the charcoal adsorption capacity per unit volume was larger, the spontaneous combustion time was longer, and there was no self-explosion.

In another experiment, the worker ants threw the cracked mystery ball directly into a clay pot filled with water, the light blue liquid had a lighter gravity than water, floated above the water, and then began to burn violently uncontrollably, causing a huge explosion, the experimental nest collapsed, the gravity stone hammer was damaged, and six worker ants participated in the experiment died.

After repairing the experimental nest chamber and gravity stone hammer, new experiments were conducted. This time, the cracked mystery ball was thrown into a clay pot filled with liquid grease, and the pale blue liquid sank under the grease without burning. After standing for about three days, the light blue liquid is still stable. It can be seen that this liquid can be stored in grease for a long time.

In the next experiment, the large worker ants asked the grease to be replaced with ant glue that had not yet solidified, and the reaction of the light blue liquid was the same as the previous experiment, after the ant glue dried, it became a thick film, and the light blue liquid was sealed in a clay pot, and there was no spontaneous combustion and spontaneous explosion for three days.

In addition to these experiments, there have been some cases of failure, resulting in deaths and injuries, which will not be repeated.

In addition, the little secretary II also carried out some experiments on his own.

She had a worker ant drink a light blue liquid stored in the grease during the experiment, and the hapless worker ant was quickly burned to ashes by the spontaneously combustible liquid in its body...

Later, the second secretary asked another worker ant to drink the liquid in the waste mystery ball, which was no longer heated, but the worker ant was not burned to death, but soon fell into continuous unstoppable diarrhea, and finally died of dehydration that night.

But before the worker ant died, the little secretary II received a message from her tentacles that the liquid tasted similar to fluorescent bacteria.

Worker ants often have to go to shifts to plant fluorescent bacteria on the fecal culture medium, and their tentacles have been exposed to fluorescent bacteria and understand the taste of fluorescent bacteria, so they can feel this way.

The little secretary II felt that she had found something, and she quickly asked the ants to find some fluorescent bacteria, which were everywhere in [Dongyang City].

After mashing the fluorescent bacteria in a clay pot with a wooden hammer, some turbid pale blue liquid was obtained, which emitted a stronger light than usual when it came into contact with the air, and quickly dimmed.

When the liquid mashed by fluorescent bacteria is filtered and clarified by hemp fiber plants, the resulting clear liquid is very similar in color to the liquid in the waste mystery ball.

When the worker ants touch it with their antennae, they think that the two taste the same. A worker ant was ordered to drink the fluorescent bacteria extract, and died of diarrhea more than half a day later.

The little secretary II quickly passed on a series of results of the experiment to the protagonist with the flying knight expeditiously.
