As soon as Donne returned to Ellington, he went to find Fiona and told her the results.

After receiving the good news of Tarris's cooperation, Fiona was refreshed and felt a lot less pressure in her heart.

Although she has great confidence in Donne, the strength gap is still too wide just relying on Ellington's strength to fight against a country. Now with the support of Taris, even if they can't fight a single soldier, just support will make Gillard have to distract her energy.

After letting Fiona announce the good news, Donne hurried to the magic Energy Engineering Research Institute.

"Lord, the magic pistol has not been produced yet..."

"I know. I didn't come here for that. Call Brian, too."

Nokia ran to call Brian, and Donne sat in a nearby chair and began to think.

In the negotiation with nitro, he promised to provide mining equipment to his satisfaction, but in fact, there is only one magic drill that Ellington can use for mining. Although the magic drill is also very good, I'm afraid it can't meet nitro's requirements.

A complete set of magic energy machinery for mining must be produced, not only for nitro, but also for the future development of Ellington. The increase of mining and smelting efficiency is very helpful to improve the speed of industrialization.

"Big brother, what can I do for you? I'm busy!"

Brian and Nokia came quickly. When they heard that Donne was coming, Elia also ran over, and then threw herself into Donne's arms with a smile.

Donne touched Elia's head and said to Brian, "I have a new idea here. I need you to help me improve it."

"New idea!?"

Brian and Nokia's eyes lit up: "about what?"

"Mine."

After a pause, Donne continued: "at present, what I'm thinking is to replace the steam engine with the magic engine, integrate it with the dwarf subway, and combine the specific environmental conditions of the mine to produce a mining car that can easily transport ore and miners."

Although the dwarf subway has been put into use by them, the dense smoke in the sealed space of the steam engine really affects the experience. If the steam engine and external combustion engine can be replaced with an environmentally friendly and more efficient wind power magic engine, the dwarf subway will undoubtedly become better. If Donne's modern design concept and ELF's artistic talent are added, I'm afraid a miraculous means of transportation will eventually be born.

"The magic energy engine replaces the steam engine to become the power of the dwarf subway? Entering the mine for transportation... I'm afraid it's very troublesome. The environment in the mine is very complex, and all kinds of caves and branches are complex, which requires a set of very complex control methods and as detailed maps as possible."

As a dwarf, Brian has a clear understanding of the mine. Dwarves never use any means of transportation in the mine. They themselves are the best tools. They only need a mining pick.

Nokia calmly analyzed and said: "the complex terrain is not a problem. As long as the track of the fixed line is laid, the forward route of the mine car can be fixed. The structure and shape of the dwarf subway only need to be slightly improved. By increasing the capacity of the car body and shortening the body, it can well adapt to the environment of the mine. Now the problem is mainly the replacement of the power source."

"That's right."

Donne nodded: "the deformation and design of the structure can be solved by your dwarf technical team. Replace the wind power magic engine as the power source, and the corresponding whole power core should be changed. I think you can find inspiration from the magic cultivator."

"If it is shouldering the role of transporting miners and ores, it has high requirements for power. I'm afraid it's difficult for a single wind magic engine to meet the requirements, at least it should be dual wind."

Ordinary wind power magic engine has only one wind magic array, so it is a single wind engine. On this basis, Donne has also developed powerful upgraded engines such as double wind and four wind, but it has not been disclosed to the outside for the time being.

"Go to the warehouse and get the engine yourself. If you need to adjust the structure, come to me. Now you need to make a design drawing of the magic energy harvester, especially how to deal with various special environments in the mine. You can ask Brian to pay attention to dealing with shock absorption, cushioning, loading and unloading. We don't have much time left. Start work as soon as possible."

Don clapped his hands and motioned them to start: "after finishing this, I have another thing you need to study."

Donne is talking about magic cars, that is, electric cars, and magic cars.

This trip to Tarris once again made Donne feel the importance of transportation. Not to mention the road, he was very dissatisfied with the speed of the dragon car alone. He could only run more than 200 kilometers in one day under good road conditions. On the earth, he could drive in an hour.

Now the Star Diamond bank is working overtime to pave the road. With the gradual familiarity with the workflow, the efficiency and speed of paving the road will be further improved, and the main road from Ellington will be paved soon. It is also time to consider the problem of magic car.

Most importantly, if the magic car can be completed, the corresponding heavy transport vehicles and armored vehicles will have certain production conditions. If the war really breaks out, the transportation efficiency of Ellington will be several times that of other forces, which can even determine the outcome of a war.

Nokia left in a hurry. His engineering team needed time to analyze the design drawings of the dwarf subway. The mine car was different from the dwarf subway, but after Donne explained it briefly, they immediately understood what Donne wanted.

The utility model relates to a rail transit vehicle that uses the power of a magic engine to transport the ore from the mine and transport the miners into the mine at the same time.

With the design drawing of the dwarf subway and the mine environment simulation provided by Brian, Nokia said with confidence that the task was not difficult.

"Big brother, are you busy again..."

Elia reluctantly pulled Donne's sleeve and looked at him pitifully, like an abandoned little dog.

Donne sighed: "because there are many things, how is Elia's magic learning recently?"

"Big brother, look!"

Elia immediately showed Donne her recent learning achievements happily. Fireball, ice hockey and arcane ball flew around her and danced around each other. There was extremely pure power inside, but there was no leakage - her control over magic has been strengthened to an incredible degree.

With the help of the magic Energy Engineering Research Institute, during the continuous study of the magic array, her control over magic has been further strengthened. At the same time, Elia also has a profound understanding of magic thanks to the words and deeds of the elf scholar Pamela.

She has not yet awakened the goddess consciousness, but now she is a super magic genius with terrible potential. It is precisely because of Elia that the magic energy engineering research institute can produce a small amount of magic pistols in the laboratory.

"That's great!"

Donne praised her, and then said, "Elia's power is very strong. Now the big brother needs your power and needs you to help produce magic pistols in the Research Institute. This is something that only you can do. Do you understand?"

"Yes!"

Elia nodded fiercely, and all the grievances in her stomach disappeared, leaving only Donne's praise and trust in her. Full of happiness, she agreed to Donne's request without hesitation.

After all, she's only twelve... Oh, she's thirteen now.

Looking at the little girl bouncing back to the Research Institute, Donne was in a complicated mood. He always felt that it was wrong to use children like this, but if her magic talent was not used like this, it would be too wasteful.

Donne shook his head, stopped thinking, and rushed to the Blackstone cave.

The construction of Blackstone cave has been very smooth. After the opening of trade routes with the surface world, the dark elves and red stone dwarfs have obtained a large amount of materials in a short time, and they have also obtained a large amount of food in the transaction with Donne. They don't have to worry about the threat of hunger. After that, they cooperate unprecedentedly.

Not only did they jointly build Datang military factory in Heishi cave, they also began to cooperate to explore the underground world. The huge underground world has complex branches, even broader than the surface world. Such a huge area is enough to meet any of their needs.

With the help of element organisms, the construction of Blackstone cave has come to an end. As an industrial production base, it has already met the standards, but as a living area, it still has some conditions. What these element organisms are finishing is the construction of the living area.

"The central area, metallurgical area, forging area, mold area, finished product area, experimental area, etc. have all been built and can be put into use at any time. The melting furnace does not drain ground fire lava according to your instructions, waiting for you to ignite it in person. The water source refers to underground running water, which can be used whether for drinking or forging. Of course, according to your instructions, the water source is entering the Blackstone cave After that, it was divided into drinking water and industrial water... "

Sitting opposite Donne is Lola's guard captain Haley. She was sent to take charge of the construction of the black rock cave. At the moment, she was secretly aiming at Donne while reporting to him. Her smooth little feet were still rubbing on Donne's legs.

The guy kept winking at Donne, and after a while she went too far.

"How many people... Oh, the dark elves would like to work here?"

"After hearing your reward, more than 200 people are willing to work here, but most of them are men. I'm afraid the queen won't agree to let them leave."

Haley rubbed her toes against Donne's Party Central Committee and said, "those men have no time to practice. Their magic cultivation is very poor. Queen Lola decided to replace a group of elites and come here herself - anyway, the current queen is her majesty lolin, and she has resigned..."

Donne was in a trance. Then he suddenly reacted. Laura, who has always been in charge, is not the queen for a long time. Rowling is the queen

"Hiss, get down to business, don't move!"

"How can I say it's disorderly movement? I'm reporting my work."

Haley pursed a smile and made it worse.
