[Thank you for the reward, Diao Min wants to harm me~]

The Prud Empire has a long history, dating back to the middle of the Fighting Spirits, and the city of Kells has been the capital of the empire ever since, standing tall in countless battles along with the prowess and glory of the Prudians.

After three days of traveling, and finally on the morning of the fourth day, the carriage came to the vicinity of the city of Kells, and Cheruth looked at the mighty and majestic city wall from afar, and I wonder if it was deliberate, the traces on the city wall were not erased by the ruler, but hung there like a medal, as if to tell people that this city, which had survived countless wars, was still impregnable.

Next to the carriage, William and his guards rode on the side, and after three days, William, who acted quite measuredly, made a very good impression on both Herrot and Cheruth, and William seemed to be deliberately increasing his impression in front of Hero - of course, the very self-aware William did not think anything wrong about Herlo, but seemed to want to get the support of Herlo, who had some connections with his own chamber of commerce.

Both Harrow and Cheruth could tell that William was not a man who was willing to be a humble illegitimate child for the rest of his life.

As for Zero, although the injury recovered quickly under Helo's treatment, as the carriage got closer and closer to Kells City, Zero's mood seemed to be getting lower and lower, and the personality that was originally a little cheerful under the efforts of Cheruth slowly became a little dull and silent, which made Cheruth feel very regretful.

Soon, the carriage came to the gate of the gate of the imperial capital of Kells, because the goods entering the city need to be checked, so the group had to wait at the entrance, fortunately there were only two groups of merchants in front, and they were all small caravans with only three or two small carriages, and they would not fly much time to check.

"Miss Herro, if you don't mind, come with me to the Seagull Chamber of Commerce branch in Kells, and the Seagull Chamber of Commerce will be happy to offer you a place to stay here. ”

Behind waiting for the inspection, William, who was on a horse, leaned over to the front seat of the car and said to Helo, who nodded.

"Well, I'm sorry, I've been bothering you for the past few days. ”

"Miss Harrow has always been a friend of the Seagull Chamber of Commerce, and your presence will surely honor the members of the chapter. ”

After learning that their purpose was to travel to the western border of Prude via Kells City, William said that he knew that the branch of Kells City would return to Freeport on the west coast in a few days, and if Harrow and Cerrus were not in a hurry, they could spend a few days in Kells City to relax, and then follow the caravan of the Seagull Chamber of Commerce on the road.

Cheruth, who came out on an adventure for the first time, expressed great interest in the capital of the empire, one of the six major forces on the continent, and following the team of the Chamber of Commerce could save some trouble, so Hero agreed, and they had no reason to refuse William's proposal to settle in the Chamber of Commerce, after all, it was the other party's kindness.

Soon it was their turn, and although the guards at the city gate were obviously not too able to understand why there were ripe red apples this season, after Cheruth gave him a taste with a childlike (pretended) expression, the guards let her go, but Helo took Cheruth into his arms as soon as he entered the city, and lectured her fiercely with two small fists against Cheruth's temples.

"That's the slave's apple!"

"It hurts, it hurts...... Wrong, I know it's wrong, Sister Helo. ”

However, the two men did not quarrel for long, and they were soon taken aback by the sight of the city.

Whether it is the Nolan village or the adventurer's town in Cheruth's memory, or the Prud village and small town that she passed through along the way after leaving the Umel Corridor, the people's clothing, lifestyle and building style are very similar to the medieval Europe of Cheruth's previous life, so Cheruth thought that Kells City was similar in style to those small cities after seeing the tall walls of Kells City full of medieval style, but because it was the capital of the empire, it must be quite prosperous.

However, the first thing Cheruth saw when she entered the city, the tall metal poles with a lamp on top of the road, subverted her judgment.

That, no matter how you look at it, it's a street lamp......

Originally, because it was the imperial capital, the people were brightly dressed, and the main streets were paved with flat and neat stone roads, which were no problem, but on these foundations, a tall street lamp suddenly appeared at intervals on both sides of the road, and somehow suddenly gave Cheruth a feeling that the times had changed, as if this was no longer the Middle Ages, but a Europe that was about to enter the industrial age.

"Oh...... Although I had heard before, Kells City finally had its own urban magic circuit. ”

Harrow's reaction was not surprised but a little sigh, obviously not the first time he had seen such a scene.

"What is that?"

Chelus asked, feeling that she had underestimated the world's magic engineering skills before.

"It's a magic guide engineering technology that just appeared a few years ago, and the magic guide relies on the magic energy provided by the magic crystal to work, you should know this, right? The city magic guide circuit is to set up a powerful enough magic energy extraction circle somewhere in the city and connect it to the magic energy transmission circuit covering the entire city, so that you can uniformly supply energy to the magic guide in the whole city. ”

Sounds so high-end...... It's like an electricity grid.

Cheruth was utterly shocked by the concept of the city's magic circuit, but Harrow's explanation relieved her slightly.

"Ah, but although theoretically this network can provide energy to the home magic guides of the entire city's residents, in fact, because there is no way to extract the corresponding amount of magic energy according to individual needs, it can basically only be used to function for a single type of magic guide. ”

Knowing that Cheruth had a strong curiosity about human magic engineering, Harrow patiently explained to Cheruth.

"Well, for example, the amount of magic energy required for each magic guide lamp to light up is the same, but this size of magic energy can't make a big guy like the magic guide furnace work, and if the magic energy strength of the circuit rises to the level that it can make the magic guide furnace work, then if the magic guide light is connected to the circuit, it will make the magic guide light break directly because of the excessive energy supply, so you understand?"

Cheruth nodded, I see, that is, although there is a prototype of the city's power supply network, but for the energy of magic energy, the people of this world have not yet invented something similar to a transformer like the earth civilization in the previous life, so there is no way to effectively use it.

"It's worthy of Miss Herro, she is really knowledgeable, is Miss Cheruth interested in magic engineering?" William, who was walking on the side, also heard a little sign, and also smiled and spoke, "No wonder the two of you are going to the Kingdom of Lorris, although I haven't been to the royal city of Loris Stoleia recently, but it is said that the urban magic circuit there can already supply energy to a small number of household magic guides, of course, there is a fee." ”

"Really?"

Helo was a little surprised, but she was not unhappy that her own statement was denied, after all, she was only one person, and she couldn't grasp all the information on the entire continent.

"That's right, it is said that it is because Lorris has implemented a new standard for the production of civil magic guides, and some of the civil magic guides with a similar energy supply size to the magic guide lamp have been redesigned by the people of the Lorris National Magic Guide Engineering Institute, so that these magic guides can be driven by the same energy supply as the magic guide lamps on the street. ”

"Oh, it's worthy of being the number one magic engineering kingdom in the mainland. ”

Hero sighed, Cheruth was a little unimpressed, did not find a way to adjust the size of the energy supply but adjusted the energy supply machinery, this is just a symptom but not a cure, not to mention anything else, she can see that it doesn't take too much magic energy to make the magic guide lamp light up, and there shouldn't be many magic guides that can operate with such a little magic energy.

"However, the city magic guide circuit is only the first thing that the Loris Kingdom made a few years ago, I didn't expect the Prude Empire to be introduced into their own country so soon, and the slave family seems to be ...... when I heard that the emperor of the Prude Empire Don't you like such a bold man?"

Harrow asked suspiciously, the Prud Empire and the Kingdom of Loris have always been in a semi-open state of hostility, the magic guide Loris, the brave Prude, just like the Lorris people think that the Prud people are a group of wild people who only know how to fight, kill and kill without civilization, the Prud people also think that the Loris people and their magic skills are just opportunistic, not really powerful.

"Ah, actually, this set of urban magic circuits has only recently been completed, and it has not even been opened except for a few small areas for testing, and it is a set of technology that Butler, the prime minister of Prud, bought from the Kingdom of Loris at a huge cost last year. ”

William explained as he walked.

"Of course, the Lorris only promised Butler to install and debug the network, such as the magic circle composition and rune coding necessary to maintain the network, all of which were directly installed after the finished product was made from Lorris, and the Pruds did not steal anything useful at all, plus there was no climactic magic guide making technology like the Lorris Kingdom, and this circuit had no other purpose except lighting and energy supply, so Butler's political enemies criticized him for doing a rather thankless thing for a while. ”

No, this Butler Prime Minister is really powerful, Cheruth thought to herself, it is easy to say that Shiyi's long skills are easy to control, but in fact, there are really few people who can so decisively abandon prejudice and carry out it under great pressure.

Neither Cheruth nor Grey Wind, who were lost in thought because of William's words, noticed that when William said the name Butler, Zero's body, who had been sitting listlessly in the back of the carriage since entering the city, suddenly moved, and a complicated light flashed in his eyes.

“...... Deed, Cheruth, I'm leaving. ”
