"Cement … I've never thought about this. But if we use cement, the raw materials … Oh, that's not a problem. "
Kardashian only remembered who made this map halfway through her words. For Pucasto, finding suitable materials to make cement was a piece of cake.
The cost of building cement roads and bridges was much lower than letting sorcerers cast spells. After all, sorcerers were used by Roddy as senior engineers. It was a great waste for them to do low-level repetitive work.
"You know how to do it from research and development to popularization. The roads we're building now can still be used for a few years. So, after the cement is made, it's more suitable to use it to build bridges on rivers to reduce the travel time between cities. The economy will naturally rise faster. "
The saying "build roads first if you want to get rich" was not a joke. Only when the trade routes were opened could the economy rise faster. The closed agricultural model of stagnant water must be eliminated quickly.
"You said one problem. What about the second one? I don't think the internal combustion engine is as difficult as you said. I think it's enough to produce it for our own use. "
"I'm not an expert on this, so I want to discuss it with you."
Rody did not have the habit of being headstrong and self-opinionated. He gave his own judgment. "We are pressed for time. If we want the train to use a mature internal combustion engine, I am afraid it will take a long time. The difficulty of research and development and the problem of fuel are the main points. I chose the steam engine because there are two large open coal mines in Efta. For trains and ships, the technical difficulty of loading the steam engine is much lower than that of the internal combustion engine. I remember that the steam engine is very simple to operate and easy to maintain … So, do you think it's reliable to use the steam engine? "
Roddy knew there were many kinds of internal combustion engines and the principle of the piston stroke. But knowing was one thing. He was completely clueless about the angle of the crankshaft and how to make the cylinder. But Kardashian was different. She had read about this. It was not impossible for the amazing Dragons in her memory to copy a modern car engine.
But the industrial level of the Kingdom of Karen was a huge gap. Maybe it would be fine in ten years, but now …
Kardashian thought for a while. Unless she could get a group of Dragons to work as workshop workers, each of them taking care of stamping, casting, and processing technology … it would be impossible to build a reliable internal combustion engine. As for oil — he had no experience in things like drilling oil wells to purify it.
Although with the help of magic, it would definitely not be as difficult as the research on Earth, but the problem was indeed as Roddy said: there was not enough time.
"If it's a steam engine … I've seen some blueprints at that time. It seems to be the kind used in trains." There was no need to doubt Kardashian's memory. She nodded. "If there are enough coal mines, steam engines do have an advantage on trains and ships. In this way, we can indeed save a lot of crystal stones …"
"That's right. In fact, we're already leapfrogging the technology tree. After all, we haven't even solved the problem of feeding ordinary people. The contradictions of an agricultural society … "
"All right, all right. You can think about these things. I'll go and execute them." Although Kardashian had lost her identity as a Dragons, she would not think about problems from the perspective of ordinary people. "The Agricultural Research Department has already made some progress. They will start to try it in the spring. Here, tell me which mines to mine and make a list. I'll arrange it."
"Well, I'll write a list for this later."
Roddy paused and suddenly said, "Can you still remember about the internal combustion engine?"
"I've seen the profile of the four-cylinder engine in cars. I only know the principle of the gas turbine, but the precision of that thing is too high …"
There were many kinds of internal combustion engines. The most common was the piston engine in cars. But the ones used in ships and airplanes were the gas turbines … The principle was similar, but the structure was very different. Kardashian's mind flashed with the information of the engine's structure. Her eyes lit up. "You mean … we have to do the internal combustion engine too?"
Roddy looked around and closed the door with a spell. He also cast a soundproof barrier. "The High Elves had such a powerful crystal civilization, but they were destroyed by the Beastmen. I guess it's because magic and the crystals didn't work at the critical moment."
This speculation had actually been partially proven. Roddy could use the crystals to unify the world. But what if the enemy was the demons? What if he was sealed like the High Elves?
Of course, Kardashian had also thought about this. Now that Roddy said this, she narrowed her eyes. "Then … are we just going to develop gas turbines and steam engines?"
"There's never too many ways to deal with the enemy."
Roddy closed the projected map and replied in a low voice.
Hearing this, Kardashian did not say anything, but her eyes shone with excitement.
That night, Rody once again met with Lachman's envoy, Mislan. After a discussion, Rody expressed that the Cullen Kingdom would support the Cullen Kingdom as soon as possible. After that, they signed an agreement regarding the debt they had borrowed from the Cullen Kingdom. The most important part of the agreement was that the Cullen Kingdom would intervene in the war in the form of mercenaries in exchange for debt forgiveness.
The Rahiman Parliament argued endlessly about the amount of debt forgiveness. This was because the Rahiman Sea, which was ruled by the Mages, had never engaged in a mercenary war. Moreover, ordinary mercenaries and the elites of the Kingdom of Karen were not on the same level. Therefore, it was difficult to determine the cost. In the end, the final goal was to "successfully quell the war within a year". If it was completely achieved, 60% of the debt would be forgiven. The repayment period would be extended for two years and the interest would be reduced.
Other than the resources in the Rahiman Kingdom, everything else would belong to the Kingdom of Karen.
In the agreement, Roddy's army had to arrive in Rahiman within four months. This was because there was usually a conscription period for wars. From the time the Kingdom gathered the army to the time the army arrived at Rahiman by ship, it would take at least three months.
Roddy agreed to this agreement after going back and forth on some conditions. He also understood that it was unrealistic to directly forgive all the debts. No matter how many conditions he had discussed, it was impossible. Firstly, the hiring fee was not that high. Secondly, it was the game on the political level.
What the Kingdom of Karen needed now was other things. Needless to say, all kinds of resources and people were needed. The "spoils of war" clause was the main reason why Roddy was interested.
From Houdini and Evelyn, he knew that there were many rich countries and lands in the northern part of the Rahiman Kingdom. As a country that overthrew the religious countries and established the Mages Parliament system, they had always adopted the policy of supporting small countries to fight against Eiseka. They did not conquer these countries one by one. Therefore, if Roddy's army was strong enough, the spoils of war would definitely be abundant.
