After Heiry become the new king of Junshin Kingdom which is now called Heiryspere Republic. Heiry had focused on their agriculture and Constructions, but their military forces was also cannot be ignored. Even Heiry was just newly crowned as the king their military strength is one of the most feared in terms of strength.
They have 50,000 active Knight's from the past administration, in the past it was 80,000 but since the defeat of the former king it dropped into 50,000 their individual strength goes to Class C to Class B(+). They also have Undead soldiers from Ains, 500 Death Knights, 200 Death warriors, 200 Skeleton Archers, and 1,000 Skeleton swordsman. Demiurge had also given Heiry two of his 5 Demon Generals, Barbariccia and Alocer. Rimuru had also given Heiry the "Blue Numbers" so that Heiry will have a. flying unit in case a war emerge. In addition Heiry's power which is the Ultimate skill "Summoner" which allows him to summon anyone of his strong allies.
All in all Heiry's Army is one of the most formidable forces in the continent next to the Falmuth kingdom and the Equilibrium Kingdom. It has a total number of 54,000 troops, Heiry assigned "Erza Scarlet" to command his entire Army.
Erza has divided the army into 3 Units, The Melee Unit, Range Unit, and the Flying Units. She categorized the troops according to their style of battle. Alocer will be the commander of the Range squad, Sebas will be the commander of the Melee squad with Tuare as his assistant Commander, while Barbariccia will be the commander of Flying Unit.
With these military force even low in terms of number but their formidable in strength, They can colonize even big countries.
Heiry had assigned Shuna to be his vice president "Shuna I want to assign you as my vice president in this nation, is that okay to you?" Shuna replied "It would be my honor to be your vice president Heiry-sama."
"I will be needing your help to improve this country." But the truth is he just want to pass his obligations to Shuna.
3 months have passed and Heirysphere Republic is massively getting economically advance, leaving behind other Nations specially the Dessert Kingdom. One day the most trusted man of the Dessert Kingdom's prince was spying at the Heirysphere Republic, he was stunned seeing the advanced economy pf Heirysphere Republic.
He came back to his king reporting all that he saw at the Nation. "Your Highness I came back to tell about the updates at the Junshin Kingdom" He said while kneeling at the front of the prince. "I thinks it is now impossible to conquer their Nation no, They've appointed new Leader it's Heiry the Adventurer and the Kingdom is now called Heiryspere Republic"
The prince was surprised hearing the news, "Please continue" he said to the spy "Yes! their country is now economically advance compared to our Kingdom. They've build 20 meters long walls across their whole country separating from other countries, on the top of the has Magical canon's that can show around 300 meters distance. Also Undead legions and The Knight's of their Nation has been roaming around ensuring the safety of their people."
"I see, so now there's no way we can defeat them". The prince said "Yes! after they defeated us in our first attack, their force have become a lot stronger."
Suddenly one soldier have interrupted their conversation. "Prince Elrick!, a diplomat from the Heirysphere Republic has come."
It was Narberal Gamma and Delta who came to give Heiry's message to the Prince of the Desert Kingdom. "Your Highness! May I ask your name?" When Nabe said these words a soldier said "How disrespectful you are?, how dare you said such thing to the prince of the Desert Kingdom."
Delta got triggered to the soldier and shot him using her Paralysis Bullet. The soldier got paralysed, Prince Elrick has apologize to what his soldier said and ask what they wanted. "I am Prince Elrick the ruler of these Kingdom, may I asks what you've came here for!?
"We're here to pass Heiry-sama's message to you!" Nabe then said all that Heiry wanted to say "By the way Heiry-sama wanted to have a personal conversation to you Prince Elrick, he wanted you to visit at the Heirysphere Republic."
The Prince was determined to go to the Heirysphere Republic, but his loyal warriors were hesitant "Prince Elrick! These might be a trap, don't go with them!" they said having Uneasy mind. "I know but we should do these or else it will be the end of our Kingdom"
The prince come with Nabe and Delta to the Heirysphere Republic, while they're traveling Delta found that Nabe was a little nervous, "Nabe why are you looked so nervous?" She ask. "N-no I'm alright" She replied while blushing, next to her was Price Elrick, he ask "Are you alright Miss Nabe?" Nabe blushed more hearing what the prince said.
It turns out that Nabe fell in love with Prince Elrick at first sight. The reason why she also have a feeling of love is because she's not an NPC that Heiry had created, The only NPC's that Heiry created was, Rimuru Tempest, Ains Oowl Gown, Mavis Vermilion, Zeref Dragneel, and Macarov Dreyar. The other NPC's he have is not really an NPC that he created, they are what called the villagers of the Empire Maker game, Just like the Goblin tribe of Gobta, Rimuru found them at a forest in the game and he decided to rule them and so as the other member of Heiry's family.
After a day of traveling they have arrived at the Heirysphere Republic, Prince Elrick was surprised and amazed by the growth of the Nation. Heiry would like to talk to Elrick to discuss some matters.
"Prince Elrick I'm happy that you came here" he said. "And so I am, I'm happy that you invited me in your Nation."
"Well I would like to say sorry to you for what the previous administration in our Country where they have claimed your territory without your permission."
"But I am afraid I can't give it back to you, I'm sure the people in my Nation will not allow it"
"Oh! no it's okay I forgot about the matter for a long time ago, since the day you have defeated us in that war I already concluded that I can't just get it back!"
"Hmmpp, but don't worry I will make a way to help you, and so I want to make a treaty to your Kingdom." Heiry said formally"I already had a treaty with the Equilibrium kingdom and the Falmuth kingdom." Elrick was surprised hearing these "H-how did you make treaty to that countries, I heard that their economy is so advance than the other countries"
The next seconds Rimuru and Macarov, came to the meeting hall, "Heiry-sama you called us" Rimuru said while bowing down to Heiry.
Yes, thank you for coming, Rimuru and Macarov. I wanted to introduce you to Prince Elrick and discuss the possibility of a treaty between our nations."
"It's a pleasure to meet you, Prince Elrick. We've heard much about your kingdom."
"Indeed, we've heard that you are a skilled leader and a worthy ally. We look forward to working with you."
Elrick got even more surprised seeing two of leaders of the riches county bowing to Heiry. "These two are my loyal servants and part of my family" Elrick was stunned with what he knew "Wh-what so basically these two Kingdoms is your domain!?"
"Hmmpp! we can say it that way!"
"But why do you want to have a treaty to our country, you'll gain nothing From our country it's just a country full of Sand."
"I'm honored that you would want to make a treaty with us. But what do you hope to gain from it?"
"As I mentioned earlier, I believe we can establish a mutually beneficial arrangement. Your kingdom has valuable resources that my nation could use, and we can provide you with the water you need in exchange. It's a win-win situation."
"I see so it's settled then"
After Their meeting Prince Elrick goes back to his country, bringing the good news.
