Gear city is the most similar city on earth that Donne has seen in prandal in the past two months.

Such a big city is full of the style of Steampunk, huge structures exposed to the air, gears coated with black lubricating oil, pipes spraying hot steam everywhere, and a thick smell of familiar haze in the air

If not for the architectural style of dwarfs and humans, Donne thought he had come to Europe in the 18th century.

Donne found coal and oil not found by the dwarves in gear city. It is precisely because the dwarfs developed and used these fossil fuels that gear city is full of pollution and haze.

Donne has no intention to stop the Dwarfs' development, but for him, magic crystal is a clean energy alternative to coal and oil. The total reserves of this strange thing in prandal far exceed coal and oil. In Donne's view, magic crystal is the world's greatest wealth.

"Are you interested in Blackstone and black oil?"

Croto noticed Donne's vision: "human beings don't seem to explore the value. These two things are very cheap, but the combustion effect is very good. It can bring a lot of heat energy, and the steam engine is very convenient to use."

"Black stone? Black oil? Oh!"

Donne shook his head. "In fact, I know the value of these two things, but I don't like them - seriously, because they burn, the air is terrible!"

Croto smiled. "We really like the taste."

"I hope you won't get any strange diseases. The smell here is really bad."

"We've been trying to find a way, but we haven't found a perfect substitute yet. At the beginning, our ancestors also used black stone and black oil as fuel, but in the records unearthed from the ruins, they later found a stable and efficient energy. Maybe the magic drive you said is a good way before we find that energy."

"Let's work together."

"In a word, we have been studying how to use other means to stimulate the energy in the magic crystal, but now the only achievement is --"

Before croto's voice fell, he heard a dull "boom" in the distance. Croto shrugged: "as you can see, the only achievement is to turn the magic crystal into a bomb. If you can't let the magic crystal, it's difficult to stably release the energy inside."

"Some devices use the energy of magic crystal, but after we restore it, we haven't figured out why they can stably extract the energy of magic crystal. Now we are decomposing in reverse, hoping to understand this problem."

"If this problem can be solved, new energy will not be a problem."

Donne nodded in agreement. Compared with humans on earth, dwarfs actually have more advantages. The world has abundant resources for them to use, and no race competes with them. Moreover, they also have relics left by their ancestors that can be excavated, from which they can master technologies far beyond the current scientific and technological level, which is very helpful to their development.

Donne didn't stay in gear city for long, on the one hand, because the air here was terrible, on the other hand, cloto was so enthusiastic that he couldn't wait to marry those dwarf beauties immediately and settle down in gear city.

Donne hurriedly arranged the teleportation array and returned to forge hammer castle with teleportation.

He did not connect gear city's transmission array directly with forge hammer castle's transmission array, but planned to transit through Ellington.

He is not a selfless person. Since prandal's transmission array technology has been lost, this is his exclusive technology. Of course, we should maximize its value.

He plans to build Ellington into a transfer station. All people who pass through Ellington must pass through Ellington. In this way, with his development, a steady stream of people will gather in Ellington, and many people who see business opportunities will gather in Ellington. Over time, it will become a prosperous commercial city.

Before that, of course, Donne had to hold Ellington firmly in his hand.

Dunn spent an hour at hammerforge, made his first deal with durandon, bought a batch of finished copper ingots, and then sent them back to Ellington.

After returning to Ellington, Donne came to the big square under construction.

This big square is the central area of Ellington he planned, and it is also the transportation hub and transfer station in the future. Donne has his own plans in the areas around the square. Most of them will be his key industries in the future, leaving a small part for his future partners.

"Lord!"

Uncle Depp, who was carrying a huge stone on his shoulder, was helping those people build. When he saw Donne, he came to salute immediately. The huge stone almost hit Donne's face.

This is Elsa's meaning. Since Ellington is so busy now, the guards can't be idle. They can just combine exercise with construction.

"Don't be polite. Go and be busy."

Donne waved his hand and began to build the transmission array.

As a transmission hub, the quality of Ellington's transmission array must be reliable. Donne originally wanted to put it in place in one step, but after taking out the star boundary square crystal, he hesitated and put it back.

Now Ellington's strength is still too weak. If someone covets the transmission array and takes it away, he will lose more than he gains.

So finally, Donne first arranged an ordinary transmission array, the quality is only a little better than forging hammer castle and gear City, and then arranged an alarm magic array. If the transmission array is in danger, you can inform him at any time.

After engraving the spatial coordinates of forge hammer castle and gear city into the core of the transmission array, Donne activated the transmission array. The runes on the transmission array of forge hammer castle and gear city in the distance immediately lit up, resonated with each other and began to establish a stable spatial channel.

After the space channel is established, the space door will not be opened directly. The magic crystal on the transmission array only maintains the space channel. During transmission, the transmission target needs to consume the magic crystal by itself.

Can I collect tolls in the future?

Donne rubbed his chin and got inspiration from online games. Of course, his own transmission can avoid the toll, but in the future, others... It shouldn't be too much to charge double the magic crystal consumed by transmission?

This method is completely feasible!

Donne clapped his hands and laughed.

If Ellington's transmission array extends in all directions and becomes a transportation hub in the future, you can make money just by sitting at home and collecting transmission fees.

Of course, before that, it's more important to have the power to defend the transmission array, otherwise a bully will directly drive people away and collect protection fees. Isn't that making wedding clothes for others?

"But don't think so much now. Develop slowly."

Donne is not in a hurry now, because he has secretly tampered with the three transmission arrays. Only those who have been marked with mana can use them. So far, not many people have been marked with mana.

"The mana mark is still too troublesome. In the later stage, it can be improved. Add an identity recognition system to the transmission array. The transmission array can only be used after handling the stored value card in Ellington... Well, I'm really a genius!"

Donne became narcissistic again. At this time, the light on the nearby transmission array flashed, and a small figure appeared on the transmission array.

"This is Ellington?"

"Croto!?"

"Hey, hey, I can't wait to see the transmission array activated."

Looking at the busy construction scenes around him, croto was a little surprised: "your territory... Doesn't seem to have been built yet?"

"No, it was originally a small town, but I felt that the space for development was too limited, so I made a new plan before it developed, and now it is being rebuilt."

Donne shrugged: "as you can see, it is under construction now. It is estimated that it will be built before the harvest month. After all, there were not many buildings in Ellington."

"Yes, very far sighted. The planning of gear city is also unreasonable, but I can't re plan now. I can only slowly transform it by region."

While croto and Donne were talking, there was another movement in the nearby transmission array. This time, durandon, Brian and Albert came.

"You are one step faster than me!"

Durandon was surprised to see cloto.

Croto said proudly, "dwarfs always go first!"

"Is this Ellington? It looks lively."

Albert looked around. Even though the people around him were busy and out of breath, they all had a smile on their faces.

"Of course," Brian boasted proudly. "You don't know how dead it was before the big brother came. After the big brother came, it immediately radiated vitality. I think Ellington will soon become a big city in the human country."

"What are you proud of, a dwarf!"

Durandon's black face: "this is not your territory!"

"The eldest brother and I are close as a family. Of course, his territory is my territory, not to mention a lot of my credit! Do you see the hammer they use to smash stones? It was made by me!"

Durandon and Abram couldn't bear to look straight at each other: "after all these years, your forging skills are still so bad... You can only show off among humans."

"Hum! Wait and see! When you are shocked!"

Brian turned his mouth. If they saw those machines, they wouldn't be shocked!

Then Donne noticed Fiona waving to him from the window and said, "Brian, show them around. Fiona seems to have something to do with me."

"Leave it to me!"

Brian finally smiled: "well, welcome to Ellington! Next, it's the time to witness miracles!"
