The protagonist who sits in the main nest [Qingqiu City] soon receives an experimental report from the little secret II about the liquid inside the mysterious ball, which is hereafter referred to as the mysterious liquid.

The protagonist didn't expect the scientific research team to have results so quickly, and he thought that he would have to wait until he was free to go to [Dongyang City] to participate in the experiment in person to achieve results.

This is a good thing, at least the research group that the protagonist values has the ability to function smoothly and produce results in the protagonist's absence. Although the protagonist also has a lot of guidance, the progress of the scientific research group is still obvious.

The protagonist has a slight complaint about the way Xiao Mi II disregards the life and death of the worker ants, but after a long time in this world, he also accepts this level difference, and it is better to sacrifice a few worker ants for the sake of experiments or battle goals than to sacrifice male ants or large worker ants.

The scientific research team has developed the ability to use liquid grease or solid ant gel solids to preserve the light blue mysterious liquid, so that this liquid has the conditions to be stored and used without the mysterious ball.

The protagonist is curious about the composition of this light blue liquid, and he has some basic chemical knowledge in his mind, but it is not enough to help him judge its composition by relying only on color and properties without the help of instruments and reagents.

For example, there are many substances that will spontaneously combust in the air, such as yellow phosphorus, white phosphorus, sodium, etc.

There are also many liquids with a density greater than water and less than oil, and vinegar is.

Light blue liquids include liquid oxygen, hydrogen peroxide, etc.

But none of the substances can fit all the properties of a mysterious liquid at the same time, perhaps it is a complex mixture.

It is difficult to judge the composition of the mysterious liquid with the current technical means, and the protagonist temporarily abandons the idea of exploration.

He noticed another finding in the experiment report. After preliminary judgment, the extract in the fluorescent bacteria is actually the same substance as the liquid in the waste mystery ball.

The protagonist looks up at the glowing fluorescent bacteria in the nest, and the luster is similar in color, but he has never associated the commonplace fluorescent bacteria with the mysterious orb liquid in the Destroyer's body before.

He believes that the preliminary judgment of scientific research is correct, not only the rational analysis after reading the research report, but also a kind of emotional intuition, the protagonist has always felt that his intuition is quite accurate.

If the mysterious liquid and the fluorescent fungus extract are really the same substance, it means that this substance can be biosynthesized in nature, and the origin of the mysterious orb in the destroyer's body can be slightly clearer.

Previously, the protagonist suspected that the Destroyer was an artificially created biochemical ant, but after the discovery of the skull stone in the swamp area, he became even more convinced that humans existed in this world, at least in history, and left traces.

But the latest experiments have shaken the protagonist's conjecture a little, nature is magical, many animals can evolve some functions that use chemistry, such as insects that emit foul odors, insects that spray acid and even corrosive liquids, is the destroyer a work of nature? Nothing to do with humans?

Putting aside this speculation, the protagonist thinks about it again, since the fluorescent bacteria can extract the liquid in the waste mystery ball, can this liquid be transformed into the light blue liquid that will spontaneously ignite and explode?

If they could, the Legion of the Divine Envoy would have access to a stable source of liquid without having to dissect the corpse of the Destroyer. The used rubbish mystery balls are no longer garbage.

Whether it's a baby warmer or an explosive, the source of the mysterious liquid will be more stable, after all, self-reliance is king, and there is no need to rely on combat capture as the only source of instability.

Therefore, the Eighth Route Army had to set up an arsenal under extremely difficult conditions, and if it only relied on capture, it would not be able to develop and grow.

The protagonist asks the Flying Knight to give orders to the research team, so that their next research focus will be on how to convert the fluorescent fungus extract into a mysterious liquid, and gives some conjectures of their own.

I'm the dividing line

With the deepening of the research on the mysterious liquid, and the smooth implementation of the "New River Opening Operation", the protagonist has realized that the mysterious ball and the mysterious liquid can be applied to new weapons.

The protagonist had already had some ideas before, but because at that time, there was no way to preserve the mysterious liquid after leaving the mystery ball, so the application method was quite limited.

For example, the protagonist imagines a kind of crossbow arrow, and instead of a simple sharpened wooden arrowhead, or a stone, pottery, or copper arrowhead, a mysterious ball is tied to the wooden arrowhead.

When the bolt hits the target with a ballista shot, the sheer force causes the wooden arrow to pierce the mystery ball and cause it to explode.

Such a bolt will be much more powerful than a normal bolt and stone projectile, and can also achieve area damage.

The protagonist also let his subordinates experiment with using the mystery ball as a cannonball to launch it directly with a ballista, but the detonation rate in this way is very low, and the shell of the mystery ball is still relatively hard, and it will not break if it is fired directly if it is not just hit in a solid place, and it is not as reliable as the previous method.

With the successful experience of blasting and opening the river, the mystery ball can also be combined with the tinder shell to be used as an explosive pack, which can come in handy in siege warfare, mining, and construction.

The preservation safety and power of this explosive are much stronger than black powder, and the Divine Envoy King Legion has already had suitable explosives before entering the Iron Age, and in the face of the rampant attack of the destroyer, it has to be said that it is a kind of luck to have such a new weapon.

Now, after the Mystic Liquid can be preserved and used without the Mystic Orb, its application will be more flexible and extensive.

After assigning a mission to the research team, the protagonist immediately organized Anthand to conduct some experiments in [Qingqiu City], and he had a new inspiration.

Anyway, now that the army is being assembled, there are no major combat missions in a day or two, and the protagonist can make the most of these times.

The protagonist hides in a safe place, relying on the messenger to remotely direct the worker ants in a remote and safe place, and first builds a simple gravity stone hammer that requires ten worker ants to pull.

Then smash open the mystery ball and save the liquid in a clay pot filled with liquid grease.

When a mixture of grease and mysterious liquid is applied to the bolt, a film of oil can be observed covering the surface, and the pale blue mysterious liquid sinks to the inside without spontaneous combustion.

The protagonist sends the worker ants outdoors, and the ballista squad fires the bolts.

Sure enough, as the protagonist expected, after the crossbow bolt was launched, due to inertia and friction, a part of the blue liquid under the grease was exposed to the air and began to burn violently, turning the crossbow arrow into a terrifying rocket.

However, a lot of mixed liquid was also left on the ballista's arm, and as a result, part of the crossbow arm was burned, so that the ballista had to be returned to the factory for overhaul...
