< and , gloated, but thought that they were still too weak.
So he came up with the idea of having them use <>.
"Poison gas is good. Soil contamination is not bad either."
These ideas came to him through a demon tribe with an implanted needle.
"Yes, this is good.
First, they used a poison gas that could be easily prepared.
Chlorine gas.
Electrolysis of seawater produces chlorine at the anode.
It was a very simple scientific product for <>.
Packaged in a sealed container, it was handed to the < with an embedded <> and transported to the front line by <.
This gas is yellowish-green in color with a peculiar odor at normal temperature and pressure, and is corrosive and highly toxic.
Since it is heavier than air, it flowed into trenches and basements and invaded many people.
It is said that this was the poison gas used by the Germans in World War I.
In fact, there is an effective neutralizer for chlorine gas.
It is <>, a chemical used to remove chlorine from the water supply when keeping goldfish and tropical fish.
In World War I, hypo-impregnated gas masks were developed, but chemistry was not advanced in the Ars world, and chlorine gas was used for a considerable period of time and was effective.
It was the Golem unit that disabled this poison gas.
If the golem does not need to breathe, crude or otherwise, the poison gas is of no use.
The human forces, led by several golem squads of 10 units, were able to hold off the invasion of the , even if only temporarily.
The human side also developed chemical weapons.
<.
The Golem units, which were impervious to chlorine gas, sprayed the <>.
This technology is said to have been brought about by a mysterious entity, but it is likely that the <> used some means to teach it to the <>.
This caused the defeat of the <> soldiers and turned the battlefield into a wilderness of death.
In other words, the plains here and there became a land that could not produce the food that the <> desired.
The <> was beginning to show signs of a quagmire.
* * * *
"......, that's how I guessed the <> were playing their part."
"Thank you very much, Mr. Turles. You have been very helpful."
The moderator, Jin, thanked him.
"Ah, in this way, the veil of the mysterious is being lifted one after another. I am sure that this will serve as a wake-up call for future generations.
Vivienne, the <>, is excited.
"Well, I'll tell you a little bit about the latter part of it."
"Oh, please."
Now Arnold is to speak.
* * * * * * * * * * * * * *
In the year 3153, life on the side of <> changed drastically.
Until then, the war had seemed to be a distant affair, and the war was thought to be fought under a distant sky.
When they learned that more than 10,000 civilians were killed in what is now the Kingdom of Franz ...... in what was then the , they quickly became aware that the war was something close to home.
As a result, the entertainment industry went into decline and the economy began to decline.
Civilians, realizing that the war was not going well, lost their desire to purchase goods.
More and more people evacuated from the western part of the Kingdom of Daynar, the main battlefield, and the north-central part of the Kingdom of Leonard.
More than one or two towns that used to be bustling with people have disappeared and turned into ghost towns.
Some nobles had shelters built in the basements of their houses.
There were many people who fled to the Ing region...... present day Kingdom of Egelea and Elias Peninsula, which seemed to be far away from the war.
But in the , <> rangers were using magic and were appearing in those peaceful looking regions.
They were carrying out so-called and executing operations to unsettle the hearts and minds of the people.
In other words, there was no absolutely safe and secure land in the sphere of existence on the side of <>.
Wealthy people had their own golems and automata, but by this time resources were scarce and manufacturing them was time-consuming, so privately owned golems and automata were being taken away from the people.
It was around this time that Arnold had his nearly 100 Golem automata taken away.
In 3154, Arnold was also commissioned as a magical engineer.
After a short training period, he was assigned to the Golem Research Institute in the capital city of Esia.
There, Arnold achieved great success.
< by more than 30 percent. And with almost no loss of performance.
For this achievement, Arnold is made an apprentice technical officer.
And again he takes the credit.
He developed a set of commands to avoid that occur in the when a golem that has been malfunctioned or wrecked in battle is gathered into a single unit.
This led to a significant increase in the use of waste materials, and Arnold was promoted to the rank of technical officer.
He was even put in charge of a military workshop.
He was also given the task of building a facility further underground from the basement of the fort at Fort Lutgula.
* * * * * * * * * * * * * *
"Well, that's why I built the < at Fort Rutgula," Arnold finished.
Arnold finished.
"Thank you. <
"But that's how it was supposed to be, isn't it? But that's how it was supposed to be.
Vivienne is also puzzled.
What she meant by "messed up" was that they had promoted a newly recruited civilian to an officer's rank, even though he had done well, and had even put him in charge of the project.
Normally, a civilian would have been assigned to a supervisor as a "consultant" to gain experience.
However, in the latter half of the war, it seems that there was a shortage of human resources to the extent that they could not afford to take such a long time.
"Well, it is almost the end of the . <?
Vivian reacts to Jin's words.
"I think it's difficult because it happened suddenly without any warning.
"I see. ......"
Then the old man spoke up.
"I see. Can you do it?"
After a few tens of seconds of silence, the old man began to speak.
