--Bee!　Bee!　Bee!　Bee!　Bee!

　An unfamiliar electronic sound echoes from the smartphone at hand.

　--?

　

　In order to confirm the identity of the electronic sounds, I look into the screen of my smartphone.

　--!

　Seeing the words projected on the smartphone screen, I was intensely confused.

　Huh?　Huh?　What?　What does it mean?

　The text on the smartphone's screen -- "War has been declared by the Demon King, Arisa.

　A declaration of war?　I know what the words mean. We're going to war now!　It's like you're announcing to them that you're not going to let them know that you're there.　In fact, me and Demon King Arisa are at war in a way. The problem is--

　Why would a smartphone - the system - notify you of that?

　If you look closely, the color of the words "Declaration of War" is different from the others. What does it mean....

　I tap on the word "Declaration of War".

When you make the 《Declaration of War》, the sworn force and the sworn force will no longer accept attacks from third parties.

　The effect of "declaration of war" lasts for 720 hours.

　If the sworn force fails to take more than half of the sworn force's territory within the effect period, the sworn force and half of its territory will be released to Rowe as a penalty.

　During the period of Declared War, all special effects for both the pledged and sworn forces disappear.

　The pledged force will not recover any CP during the duration of the Declared War.

　The sworn force can choose to cancel the "declaration of war" once they have taken control of more than half of the sworn force's territory.

　Once the player has declared war, he is not able to perform the war declaration for 720 hours after it ends.

　For 1 hour after the declaration of war, both the sworn and sworn forces gain the power of pseudo-peace.

　Declarations of War can only be activated against opponents with superior numbers or levels of control.　　　　　　　　　　'

　I carefully read the explanation displayed on my smartphone screen.

　To put it succinctly, Demon King Arisa has come to challenge me to a titanic battle. Since this is a fairly strong offensive strategy, the disadvantages of the side that launched the 《Declaration of War》 are quite significant.

　When I heard the explanation of the 《Declaration of War》, there were two points that caught my attention the most.

　One was the loss of the special effects. In other words, it meant the disappearance of the [Demon Restriction] applied to the controlled area. The number of invaders, which had been limited until now, was also abolished. It could be said that this was indeed a plunge into a state of war.

　The first is the Pseudo Peace, which is granted for one hour after the Declaration of War.

　I hurriedly take control of my smartphone to check the status of the controlled area.

"Pseudo-peace (53 minutes left).

　I was given 53 minutes to prepare the defense.

　Well what do we do now?

　Spread out a map of Kanazawa City and consider the preparations for defense.

　______________.　　　　　　
　○○○●●●　　　　
　

　There are four control areas adjacent to Demon King Alisa's control area. If we take the long way around, there will be more control areas that could be invaded... but in order to take the long way around, we'll have to cross humanity's land. If that happened, it would be picked up by the internet news, so they would be able to respond in time to deal with it.

　If so, the four adjacent areas of control would be the ones that needed to be addressed immediately.

　Divide up the subordinates into four areas of control.... no. If the enemy concentrates his forces in one area of control, he will not be able to defend it.

　Where can we attack?　No, we need to discard our preconceived notions of concentrating our forces on one area of control.......There is naturally the possibility that they will invade all four areas of control at the same time.

　My subordinates lined up in front of me are watching my troubled figure in silence, and time is ticking away even as they are pondering.

　--!

　Looking at the faces of Lina, Chloe, and the rest of my subordinates, I remembered exactly how it was when we were invading the Demon King Alisa's control territory, and one idea came to mind.

　Demon King Arisa had connected each of the dominant realms he controlled with a [Transfer Device].

　If a similar plan was used, wouldn't it be possible to deal with all the situations?

　I use my smartphone to execute 【Domination Domain Creation】. I connect the 【Transition Device】 to the hierarchy of the dominant domain, which is different from the four locations that are supposed to be attacked from my current location.

　Then, I will transfer all of Lina's household members and the subordinates that were waiting for them to be transferred one by one.

　With this, the maximum strength of my forces is concentrated in one place. Next, from the place where I concentrated my forces, I connect the four control areas that are expected to be attacked with the 【Transition Device】.

　In this way, you can send your subordinates to the attacked area of control at the right time.

　Next, traps are placed in two control areas in preparation for the case of the four areas being invaded simultaneously.

　In the first location, 【Poisonous Swamp】 and 【Poisonous Fog】 were set in large quantities. Demon King Alisa's subordinates are a fairy species. The poison can be expected to be effective. If we place only Living Mail, which is poison void, we won't be invaded prematurely.

　In the second location, I set up 【Pithole】, 【Dung Pool】, and a large number of shields. The aim was to lure the goblins that were expected to rush in in large groups into the 【Pithole】. By deploying Dark Elves, Goblin Archers, and Lilimu, who were excellent at long-range attacks, the goal was to kill the goblins that fell into the 【Pithole】 with long-range attacks.

　The remaining two locations are all-out warfare. If there are traps that are poorly placed, some of the subordinates, including Lina, won't be able to demonstrate their abilities. We will only set up those cloaking objects that will give us an advantage in defense, and we will repel the attacking enemies with our own strength.

　What we need to think about later.........is what happens after we successfully defend ourselves.

　Demon King Arisa failing to invade and liberating half of the controlled territory is the second worst ending for me.

　The point is to find out when to counterattack.

　The number of Demon King Arisa's control area is 9....up to the 9th level, so it's up to 9 levels.......hmm?　Wait.

Canon!

　I shout out the name of the canon - the search tool - loudly.

'Yes,'

　The search tool floats up to me in a huff.

"Do you know about The Declaration of War?
Yes. Ah!　I thought you suddenly became flustered, but did you declare war?
Tell me the conditions under which I can declare war.

　I ignore the canon's question and pose the question.

''Yes. Let's see, the 《Declaration of War》 is that the Demon King whose level has grown to 10--
All right. All right.
'What?　Huh?　I haven't explained the terms yet.

　The answer I wanted to know came out of Kanon's mouth as soon as possible.

　In the first place, how was Demon King Arisa able to declare 《Declaration of War》?

　If it's only the conditions listed in the explanation, it would be strange if I wasn't able to make a 《Declaration of War》 to a level 9 Demon King Arisa when I was level 8.

　If that's the case, do I need a special procedure like the 《Surrender》...?　--no. The answer was level.

　That meant that the Demon King Arisa's level was 10, which meant that the hierarchy of the ruling realm was also 10.

''Lina.''
What?
'How much time do you think it would take to traverse one level of the hierarchy of the dominant domain?　We can consider the enemy to be very few.
'Yes. If there are no interruptions I would estimate six hours at most.
I see.

　Knowing the answer I want to know, I enter into my thoughts again.

　The number of the Demon King Arisa's dominion area is 9....it's up to 10 levels.......so 9 x 10 levels x 6 hours ÷ 2 (Lina + Chloe) = 270 hours. 　As a backup, if we add 2 days to the total, it will be 13 days.

　The duration of the 《Declaration of War》 is 720 hours. In other words, 30 days, if we could eliminate the invaders within 17 days we'd win the war?

　The plot to victory was in sight.

'Pseudo-peace (7 minutes left)'

　All that remained was to wait for the Demon King Alisa to invade.
