Do you understand a word I say?
　I call out to the goblin covered in a sack of shrapnel.

'Wow, I know,'
　The goblin replies in a trembling voice.

　Will you learn the human language (Japanese) in earnest when you become a member of the family? I'm impressed by something else when I hear the goblin's reply.

'So it's a coincidence that you came to my dominion territory?

It's not a coincidence!

Then what is the point?

Delivery!　My head asked me to bring you a delivery!

　The goblins call the demon king who created them 'O-head'. In other words, this guy is saying that he came to my control area to bring me a delivery from the Demon King.

''A delivery........?　What?

That's it!

　The goblin sticks his hand inside his waistcoat and holds out a crumpled piece of paper.

　I walk up to the goblin and take the paper from his hand.

　I unfold the wrinkled paper and see a row of beautiful Japanese characters.

　A letter?

　I read the text in the letter.

''Mr. Demon King, whose face and name I don't know, it's nice to meet you. My name is Kanon, the Demon King who governs the dominion area adjacent to your dominion area. The goblin who entrusted me with this letter is called Gobuta. I have informed him not to do you any harm, so I ask him to be polite.

　I have been writing to you to ask you to surrender. I should have come to you in person, but as I am confined to my own domain, I apologize for sending someone else to do it for me.

　If you do not know what surrender is, I will briefly explain it to you. Surrender is an action that can only be used by the Demon King against the Demon King. The Demon King who "surrenders" offers to surrender to the Demon King and gives him the right to rule over his territory and the right to live or die.

　The merit for you is that you can gain my domain. And you can have me as your faithful follower. I have a "B" status in knowledge. I can tell you things you don't know. I think this is a great advantage.

　As a gesture of good faith, I can also tell you the demerit. If you control the Demon King's domain through normal means, your DP limit will be increased by 100. However, if you control the Demon Lord's domain by "surrender" as you did in this case, the upper limit of DP will be increased to 50.

　My lamp of life is running low.

　If you are willing to accept this "Surrender", please contact me at the following number.

　080-x-x-x-x-x-x-x.

　Kanazawa City, XX town, Demon King, Canon

　The letter was carefully spun in legible handwriting.

　In summary, I am dying. Please help me as I surrender. Is that correct?

　It even includes detailed specifications for 'surrender' in a polite way. I like the fact that it even describes the disadvantages.

　The problem is......... "Surrender".　Does such a specification really exist?

　If the letter is true, the master of the letter - the merit of the canon is survival.

　If it is false, what is the benefit of the canon?　A mental attack to make me agonize?　No, it can't be.

　When you think about it, is the letter true?

　I understand the merits of accepting "surrender". As for the disadvantages, it's hard to see them as disadvantages from my perspective right now. If it's an invading opponent, but it's currently a quiet opponent.

　With that in mind, should we accept it?　But hey.....

　I ponder the problems that have fallen and sprung up.

''Please!　I need help with my head!

　As I continued to worry, the goblin in the Zuta bag - was it Gobuta?　but shouts out a plea.

　I walk up to Govt. Govt. and remove the covered shrapnel bag.

'Question. Why do you want to help me so badly?

"...?　Why?　Yeah?

Yes.

It's only natural that I want to save your head. My head is everything to me!

'Of course?　All of them?　

No!　That's part of it, but it's not!　Your head is kind, strong and intelligent it's perfect!　So I want to help!

　The goblin species is generally not smart. Even for the goblin in front of me, his words don't get the point across.

'If you're strong, intelligent, and perfect, why should you surrender?

　It's been a long time since I've had a conversation with anyone other than a yes-man, and I can't help but ask nasty questions and enjoy the act of conversation.

''Ugh..... It's perfect, but I'm not perfect...

　Govt. Govt. spins the words - which are not even incoherent answers - desperately.

'I want you to see this!
Hmm?　...What?

　Govt. Govt. held out with a desperate thought - my gaze is drawn to the silvery white sphere.

　[True Core]........?

Why are you doing this?

It was given to me by the head as a sign of trust.

　[True Core]. The details are unknown, but if the Demon King takes it away, he will control the dominant area, and if it is destroyed by the humans, he will release the dominant area - it is the thing that the Demon King must protect the most.

　Are you in such dire straits to entrust such an important object to a dying goblin?

　In other words - is it serious enough to offer up [true core]?

　Honestly, I can't dismiss the line that it's still a trap. The content of the trap is unknown, but if the risk of failure was only a single goblin in my military family, I would enjoy the conversation appropriately and use it to feed my experience.

　However, when the risk of failure is the 【True Core】.......it's a different story. Isn't that a bit too risky?

　Isn't this a trap?　Are you sure this is an offer of surrender?

　My thoughts tilt to the current of the canon letter being true.

'Okay,'
So your head is... what?　Are you sure?

　Govt. Govt. gives him a scowling, goofy look.

'I can call the number on this letter, right?'

I don't know much about it.
"You don't know...
　I chuckle.

　I operate my smartphone and make a call (call) to the number on the letter.

　

　The unique tone sound is followed by the ringing call sound.

"Hello.........

　A thin female voice comes from my smartphone.

''Hello. This is the Demon King who received a letter from the goblins, is this Kanon-san?

"Hi!　This is the Demon King Kanon from the town of

Theon, the Demon King of XX town.

"Well, um, so, about the letter...

"Is this about 'surrender'?

What do you think of...?

'Well...'

　I hadn't come to my own conclusion yet. In front of me, Gobuta was desperately trying to worship me.

''Um........well.......if I may say so myself, I think I can be of help to you, Sion. I'm a knowledge specialist, or rather, I know a lot of things because I'm a B in knowledge.''

Such as?

''Let's see, Sion-san has evolved into a Demon King (bloodsucking species), the BP needed to grow his status from C to B is 10, and the BP needed to grow from B to A is 50. ...
That's enough. That's enough. I can't judge whether what I'm saying is true or not, but I understand that if it is true, you know a lot of things I don't.

　There were many things in the words Kanon said that I didn't know about inside. I mean, the BP needed to grow from B to A requires 50 BP........

''Then.........''
No, it's the content that counts.
'No!　That's not going to cut it!　Please respond as soon as possible!'

　An impatient voice interrupts my words.

'Are you in a pinch...?'
'Yes!　I'm doomed!　The entirety of my troops guarding the dominion territory has been wiped out!

　The entire regiment guarding the domain of control has been wiped out. Well it's all doomed.

"Understood. I accept your surrender. What do you want me to do?
'Thank you!　Please receive the [True Core] from Gobuta!''

　He takes the words of the canon and orders the Gobuta in front of him.

'Gobuta. It's an order from your head. Give me the [True Core].
Yes, sir!

　Gobuta hands the [True Core] over to me.

''I got it.''
'Thank you. Please respond with a heartfelt 'I acknowledge' after my words.
Oh, yeah.

"I, the Demon King Kanon, renounce my life as Demon King and 'surrender' to thee, Demon King Theon.

　The canon declares, sounding like a song.

'--I approve.'

　I said the words with all my heart.

　--!

　The [True Core] I received from the goblin emitted a dazzling light and disappeared from my hand. At the same time, the area underneath my feet, the space, and the dominant area vibrated violently.
