After teleporting back to the Principality of Nazarick, Draco didn't rush back to the Great Tomb but instead wandered around the city.
The tragedy that occurred in the Jura Tempest Federation had also made Draco vigilant.
What if this happened in the Principality of Nazarick?
With such a question in mind, Draco began to think about the city's defense.
Although Nigredo's spiritual field constantly covered the Great Tomb and the city, preventing anyone from setting up a Magic Sealing Formation...
"Wait, why am I being as naive as Rimuru now, only considering the best-case scenario? What if there's an accident..."
"At least I should take some preventive measures..."
After muttering to himself for a bit, Draco continued to think about the problem.
Suppose an enemy used a special magic item to break through Nigredo's spiritual field and set up a Holy Purification Barrier stronger than the Four-Corner Magic Sealing Barrier... Well, it didn't seem like it would have much of an effect on the Principality of Nazarick.
Even if Benimaru and the other monsters lost their fighting strength, there were still 100,000 members of the Demi-human Legion and 50,000 members of the Orc Legion in the city.
"Yare yare, I suddenly realized we have quite a lot of combat power."
"Hmm... defense doesn't seem to be an issue, but if the city's buildings were destroyed, it would be quite a hassle..."
Draco rubbed his chin and thought for a while, then suddenly slapped his forehead.
"Damn, how could I forget the real purpose of forming an alliance?"
Draco established the alliance for technology sharing; the war alliance was just a byproduct.
According to his plan, he could use the former crown prince Pandora's magic item manufacturing technology, combined with the forging skills of Kurobe, Cocytus, and Kaijin, and Vesta's magical expertise.
He could even add the magic scroll engraving technology of Titus, the head of the Ancient Library.
By combining the top technical personnel from the three parties, they could research technological products that surpassed this world.
Incidentally, he also had to seize Clayman's knowledge.
Don't be fooled by the fact that he was the weakest Demon Lord; his magical technology was actually quite impressive.
He had even developed things like electromagnetic waves and magnetic resonance.
Moreover, Draco knew that the Eastern Empire would eventually develop mobile phones, relying on Clayman's knowledge.
When these technologies collided, the changes they would bring would be absolutely immense.
By then, making a product to protect the city from attacks would be simple; any magic-sealing barrier would be trivial.
Just as Draco was wandering and thinking, a call suddenly came from behind him.
"Brother Draco!"
"???"
Since when did I have a sister?
Curious, Draco turned his head and saw a petite girl running toward him.
"I knew it! I definitely didn't misidentify you."
Behind the somewhat cute girl followed a blonde, blue-eyed beauty and a young Black man.
"Oh! It's Reina."
Draco suddenly remembered.
They were Otherworlders who had been summoned to this world by the Kingdom of Falmuth along with him.
The little girl was named Reina, the young Black man was Anderson, and the blonde beauty with Western heritage was named Liana.
After Razen died, they had left the Kingdom of Falmuth, and Draco hadn't paid any attention to them since.
He didn't expect to meet them here.
"Long time no see."
Draco greeted them.
"I neber expected to meet our benefactor here. This is great!"
Anderson said excitedly with his thick accent.
"Mr. Draco, long time no see."
Liana brushed her long hair and gave Draco a wink.
Clearly aware of Draco's extraordinary status now, Liana's behavior carried a hint of seduction.
However, Draco had no interest in her; instead, he was a bit interested in Anderson beside her.
The young Black man's aura was quite strong now—at least, compared to ordinary people.
It seemed he had some kind of fortuitous encounter; his strength had actually reached the peak of A-rank, just one step away from A+ rank.
"Hey, Brother Draco, are you really the king of this country now?"
Little Reina asked curiously.
"That's right." Draco smiled.
"Wow, that's amazing!"
Hearing Draco admit it, Reina cried out in wonder.
"I saw the images in the Recording Stone before and thought my eyes were playing tricks on me; I didn't believe it at first."
Reina's eyes suddenly sparkled.
"Since we've met by chance, I'll play the host properly today."
"It's my treat, let's go eat."
Anderson immediately got excited, rubbing his hands together. "I haven't had barbecue in so long; I'm already drooling!"
"Let's go, let's go, to the barbecue shop!"
Reina also nodded impatiently.
"Uh... just barbecue?"
He was a monarch after all; treating acquaintances to barbecue felt a bit cheap.
But since they suggested it, Draco didn't refuse... In the best barbecue shop on the food street, the four found a quiet seat.
"I want mutton skewers..."
"Give me a pitcher of draft beer..."
"Anything is fine with me."
While the three were ordering enthusiastically, Draco looked around at the interior decor with curiosity.
To be honest, although he was the ruler of a nation, he had never really explored the city properly.
The decor gave Draco the illusion of being back in the real world; it was a truly strange feeling.
Soon, skewers of tender, juicy grilled meat were brought out, along with a large pitcher of draft beer.
The four chatted while eating, and the atmosphere was quite harmonious.
"Speaking of which, have you become adventurers now?" Draco asked.
"Yeah, it's a rare chance to be reincarnated; it would be a shame not to have an adventure in another world."
Then, Reina chirped away, telling Draco what they had been through over the past two years.
After leaving the Kingdom of Falmuth, these Otherworlders began to travel in small groups.
Some relied on the powerful innate abilities of Otherworlders to go to small countries among the Western Nations and become nobles.
Then they began lives of indulgence with all sorts of beautiful maids.
But most became adventurers and made quite a name for themselves.
Reina's trio was a famous A-rank Mithril-level adventure party from the last two years, their fame no less than that of the older generation of adventurers.
The biggest contributor was the strongest member of the trio, the young Black man and captain, Anderson.
"It seems your lives in this other world have been quite exciting."
"Hehehe."
Anderson scratched his head sheepishly. "That's thanks to our benefactor for giving us back our freedom; otherwise, how could we live such a carefree life?"
"It was nothing."
Draco shook his head. "It was just a small favor."
He didn't take it to heart.
"Speaking of which, I remember Anderson was a mage, but now you..."
Draco looked at Anderson in surprise; Anderson was now covered in bulging muscles and looked as strong as an ox, not looking like a mage at all.
"I am indeed a mage," Anderson grinned. "But this is a type of magic application I researched myself."
"Oh?"
Hearing this, Draco's eyes lit up; he loved these strange and quirky magic formulas.
"Absorb the essence of heaven and earth, refine the spiritual energy of the sun and moon, and peer into the true essence of the Great Dao..."
"Huh???"
These lines from Anderson made three question marks appear over Draco's head.
