The legendary dragons like to pile up gold coins in their nests. In fact, when the Dragon Clan Lords arrive, a pile of useless metals is definitely a pain in their homes. Lord Pukasto obviously has no interest in gold mines and continues: "There are many coal mines and iron mines in the kingdom. Some rare mines are at the border, and there are many good things in the Gondora Mountains in Tasman."

For Roddy, such information was crucial. After he thanked him repeatedly, the lord left because he had to study the calculus.

Roddy picked up the stone and injected magic. A light curtain was projected directly in front of him. He adjusted the direction and saw the proportional projection of the territory of the Kingdom of Karen on the wall. Light spots of different colors were marked on the map, and the text noted above showed the approximate reserves and types of ore veins, as well as the types of associated ore...

Roddy had a deep understanding of the power of the dragon clan before, but this time he was still scared by the strength of the Black Dragon Lord - in such an era when mining was basically based on Mongolia, what Pukasto did was no different from satellites.

Such a message alone is a big gold for the leaders of the kingdom - or even a million gold is hard to find - the important foundation for the agricultural society to move towards industry is the first step of having sufficient energy and ore. Now, these two biggest problems have been solved by the Black Dragon Lord in three days.

Roddy didn't expect that he would receive such a gift before he was about to leave, but he stared at the map for a while and felt a little worried: he was not a real-time strategy game. The Karen Kingdom is not a large population. Whether it is mining or building roads and railways, the expenses and labor are astronomical, and he still has an army to support, and even a fleet to build...

He suddenly understood the reason why most ancient Chinese emperors were criticized by later generations: no matter what decisions he made, the lower-class people would be tortured... The so-called "prosperity, the people suffer, the people suffer, the people suffer" is nothing more than this.

Holding her chin and staring at the map in a daze, Kardashian knocked in and saw what Roddy was studying. She glanced at her and found out about it. Seeing that the other party was looking over, she threw a metal ball in her hand: "Pacasto is so neat, the problem has been solved."

Roddy didn't even turn his head, and a magically condensed tentacle caught the ball. He took it over and looked at it and found that the metal ball was extremely round, with a polished surface and heavy in his hand. He was familiar with the drawings and knew that this was the bearing bead used by the aircraft propeller, and it was also the only bottleneck for long-distance navigation.

He thought it would take some time to conquer it, but he didn't expect the Black Dragon Lord to solve the problem casually. Roddy was surprised and couldn't help but feel excited: "Is it really done? How much strength has increased?"

"The data shows that at least three times. The durability test is being done, but judging from the current situation, it can pass the test." Kardashian also sighed a little: "Pacasto personally helped increase the smelting temperature, and used spells to make a batch of beads according to the standard model, and there was almost no measurement error."

Roddy pulled the corners of her mouth, thinking that this was much stronger than the amazing "level eighth-level workers" in China's state-owned enterprises.

"Now I can see that compared with the technology on earth, the development level here is really a bit abnormal - the basic level of ordinary people is too low, and even the temperature measurement method is very primitive, and things made by the dragon lords can't match those of high-precision machine tools."

Kardashian said and exhaled: "But the bearing problem has been solved, you can finally get off."

"That's it, but after reading this picture, I'm afraid I'll have to trouble you a lot of things."

Kardashian eventually volunteered to stay in the Kingdom of Karen, helping Roddy take charge of the research department, and monitoring the cabinet - if all the core forces are gone, Sally played by Nora alone is not enough. The cabinet's power is too great at present, and under absolute power, the problem of corruption is bound to exist.

The devil invasion made Roddy dare not slacken, but the nobles could not all be willing to "serve the people."

Since Kardashian learned Roddy's secret, she is very enthusiastic about the application of "earth technology". The research and development of guided missiles has entered a new stage. Compared to finding clues in another continent, she actually tends to stay here to continue research.

So at this time, Kardashian agreed very happily: "Tell me, are you going to dig those mines? Anyway, the dragon clan is very idle. If you post a task to exchange points, someone will definitely be willing to help cast spells."

"The mining matter is second, mainly... the finances are tight now."

Roddy sat back on the chair and sighed helplessly: "For efficiency in war, most roads rely on magic to shape and solidify, and the train tracks also cost a lot of money. Now he has tried his best to open a line, but what's next? Maintaining the continuous transportation of trains is too much; if it is not transported, the cost of road construction will be in vain."

"The research department said that the effect is very good. The cargo transported is more than a hundred times more than a carriage, and the profit is... "Kardashian was stunned and suddenly reacted: "Are you saying... the energy supply?"

Roddy nodded: "I haven't made such a big deal before, but now I understand that there are so many things that I'm really doing too much."

He began to count with his fingers: "The high elves had sufficient crystal reserves at that time, but they did not engage in national transportation. Moreover, their magical abilities were strong, so there was no need to consume too many crystals in wars. But what about us? The war to Rashiman required a lot, and the trade share was also quite large. Now, the trucks that built roads, trains that kept running after opening, planes that were about to sail across the ocean, etc., all need crystals, and each one was not a one-time, but a huge consumption quota for a long time..."

If we only rely on the transformation of magic crystals and the collection of precious element crystals from nature, at the current consumption rate, the Karen Kingdom will not be able to provide it at all.

Kardashian immediately realized what he wanted to do: "Are you going to use the technology of the earth as an auxiliary? Nuclear power is definitely not a good idea, internal combustion engine? Oil..."

Roddy quickly waved his hand: "Be realistic, we can't just look at the current industrial level of cutting-edge mages. After making internal combustion engines, only the laboratory can handle processing accuracy, and mass production and maintenance are too difficult."

He raised his hand and pointed, and the tentacles condensed by magic on his back spread to the map of the stone projection. In a few seconds, it became the current road map of the kingdom.
