At present, the lowest cost way to occupy the air supremacy is hot-air balloons, but using hot-air balloons to fight is obviously a joke.

Not to mention its poor carrying capacity, slow moving speed and slow control mode, these two points have completely limited the military use of hot-air balloons.

The one that really works is the Skybreaker that croto made.

However, the Skybreaker is obviously a semi-finished product. In Donne's mind, the best air control weapons are supersonic fighters and high-altitude bombers. The former is extremely fast and difficult to defend, and the latter is located at an altitude of thousands of meters. General attack methods can't affect them at all.

In addition, high-altitude bombers can also have variants. High altitude transport aircraft can transport a large number of soldiers to the rear of the theater for encirclement warfare. This mobility is much faster than the current marching mode.

But now there are many technical limitations to realize these things, and only Mithril universal alloy can barely meet the requirements. Take off can be realized by controlling the anti gravity magic array, and the power can be realized by the wind power magic engine. In other words, the wind power magic engine was inspired by the turbojet engine from the beginning, This is a return to its original function.

Just want to integrate these technologies, there are still many problems.

The most important point is that under supersonic conditions, ordinary drivers can't bear this acceleration at all, so they must be apocalyptic, so the number is very rare.

On the other hand, how to fight at supersonic speed?

There is no computer and radar here, so we can't lock the target at a long distance. When we see the enemy, I'm afraid the two sides have collided with each other.

The control of weapons also needs computers, or something similar to computers.

Before solving this problem, the plan of the fighter can only be stranded temporarily. The improved dwarf aircraft and helicopter are the best choice at present. They are fully manually controlled, and the speed is neither slow nor fast. They can fight within the sight distance or avoid conventional attacks.

Although Donne also wants to produce his own aircraft, it is very difficult to build an industrial production line from scratch. He doesn't have the energy and need for the time being. He simply cooperates directly with croto and provides technical support to each other.

Computers are more demanding. It is impossible to restore them completely. We can only think of other ways.

Because there were too many situations to consider, Donne put the priority of this matter behind for the time being. After leaving the magic Energy Engineering Research Institute, he returned to the Lord's house.

"... Mr. Gallian, I told you before that this is naked blackmail! We won't agree to pay this bill!"

As soon as he passed the study, Donne heard Fiona's dissatisfied voice. After being stunned for a while, he entered the study and saw Fiona and Gallian confronting each other. At the moment, Gallian is not Gallian, the branch president of the Star Diamond bank, but Gallian, an arms dealer with a cigar in his mouth.

"However, dear Fiona, you must admit that my people and weapons have played a great role in resisting the animal tide. If I hadn't recklessly consumed a lot of valuable goods, Ellington would have been completely destroyed by the animal tide."

Gallian vomited a thick smoke ring, and Fiona frowned. Fortunately, it was an ornament. There was only a smell of fruit, otherwise she would have driven him out.

"The situation was urgent, so I didn't discuss it with you. I had only one idea: keep Ellington at all costs!"

Gallian said solemnly, "I did it, so it's natural for me to ask for compensation!"

"But we didn't buy those bombs from you at all! You and master croto were angry and took them out to compare!"

What Fiona can't stand most is this. It's obviously the result of the fight between goblins and dwarfs. Why should Lord Ellington's house pay instead?

Kloto got Donne's technical support, so he didn't say anything, but Gallian, a cheeky guy, came directly to the businessmen to deliver the bill - the fourth time in half a month!

It seems that there is no result this time. He is going to stay.

Don couldn't help asking, "what's the matter, your highness Gallian?"

"Lord!"

Fiona and Gallian spoke at the same time. Gallian immediately filled his face with a smile: "thank God, you finally appeared today."

Donne has been busy recently. He has been free to rest these two days. No wonder Gallian feels so sad.

"Lord, your highness Gallian has sent a bill."

"Bill?"

"Yes, about the arms bill consumed in resisting the animal tide."

Fiona took a swipe from the corner of her mouth and handed a bill to Donne: "look."

Donne took the bill and scanned it. Suddenly, he took a swipe at the corners of his mouth and said, "your ability to take advantage of the fire is really perfect, your highness Gallian."

"No, no, no, you're wrong. If you want to take advantage of the fire, I won't pass you the bill at this time."

Gallian waved his hand very seriously: "if I really want to sell at the highest price, I will secretly destroy the stability of the city wall at the critical moment of the animal tide, and then take out this price list when the animal tide is about to break through the city wall. I believe you will be willing to pay in that case."

Donne smiled bitterly. No wonder people say that the heart of arms dealers is darker than ink. Many wars are secretly promoted by arms dealers. Now it seems so.

"But your bill is too outrageous. Look at the price of this magic iron bomb. When you sold it to me last time, it was 5000 gold coins, and now it has risen to 10000?"

"The price of goods rises and falls with the urgency of market demand."

Gallian said with a natural look: "I think it's normal for me to double the price when the animal tide strikes, isn't it?"

Donne was speechless.

"You said you didn't take advantage of the fire!"

Fiona was very angry: "anyway, the bill of more than 50 million gold coins is ridiculous! Do you really know the concept of 50 million gold coins? The tax revenue of the whole Ilus empire is only 20 million gold coins a year!"

"More? Really not much!"

Gallian shook his head and said: "The expensive magic iron bomb alone used more than 2000 gold coins to resist those powerful Warcraft. This is more than 20 million gold coins. The value of the remaining bombs with various functions, such as paralysis bomb, smoke bomb, flash bomb and other special bombs, is really not much! Or do you think the arms we consume are not worth these gold coins?"

"All right."

Donne tasted something. With a flick of his finger, the bill burned to ashes. He said faintly, "tell me your real intention."

Fiona was stunned: "what's the real intention?"

Donne smiled: "he came up with such a bill we can't afford. Don't you think he really wants it?"

"Lord, you are really smart."

Gallian applauded, then quickly put away his cigar, took out another document and said, "please see."

"What is this? Do you want to take the opportunity to blackmail me and join Ellington?"

Donne opened the file as he spoke. After a quick glance, he couldn't help raising his eyebrows and said, "are you serious?"

Gallian said proudly, "of course, this is the plan signed and confirmed by the great leader!"

Donne noticed that a name was signed in a complicated way.

Leviz gold teeth.

Goblin leader, the boss of inkley risk control company.

This document... No, it should be said to be a contract, which made Donne frown.

Not as he imagined, the goblins intend to use this bill to control Ellington. The contents of the contract have nothing to do with Ellington's sovereignty. On the contrary, the terms proposed in the contract are all kinds of cooperation with Ellington.

Rivitz... No, it should be the Star Diamond bank that provides financial support for Ellington, but the requirement is that the Star Diamond bank will obtain technical support for asphalt roads and supply of raw materials. The Star Diamond bank will jointly develop and build asphalt roads between various towns in prandal with Ellington. At the same time, when charging services are implemented in the later stage, the benefits obtained will be divided according to 82. Star Diamond bank 80%, Ellington 20%.

What makes don frown is not that the Star Diamond bank wants to provide funds to build roads, but this profit share.

He knew long ago that the construction of roads could not be completed by Ellington's funds alone, and must be supported by the state and a large amount of funds. However, before he had time to discuss with Victor, the Star Diamond bank smelled the smell of interests and took the initiative.

Goblins are worthy of being commercial wizards.

"You want to invest in building roads. I welcome it."

Donne nodded and continued: "but there are two points I don't agree with. First, the cooperation with the Star Diamond bank is currently limited to the Ilus Empire, and the cooperation of other countries will not be discussed for the time being. Moreover, the partners in the Ilus Empire have to join another one. I need the support of his majesty victor."

Gallian frowned slightly and nodded reluctantly after a long time: "yes, but I believe you will still come to us for partners from other countries in the future."

Donne smiled and said nothing.

According to the Ilus Empire, it is easy to find Victor for policy support because of his unconditional trust, but it is different in other countries. The most difficult thing is the first step. At the beginning, it is difficult to find a partner. The goblins can see their interests with strong financial resources and advanced vision, so they dare to cooperate, but the people in power in other countries dare not take risks.

However, when the road construction in the ilrus empire is completed and everyone sees the huge benefits hidden therein, I'm afraid that people who cooperate will flock to it. At that time, it will be much easier to discuss policy support and cooperation with the rulers of other countries.
