"Cement...I haven't thought about it. But if you use cement, the raw material...oh, that's not a problem."
Kardashian didn't remember who made the map until halfway through her talk. For Pucasto, finding materials suitable for making cement was a piece of cake.
The cost of cement paving and building bridges is much lower than that of magicians to cast spells. After all, today's magician is used by Roddy as a senior engineer, and it is a huge waste to go to do low-level repetitive labor.
"From research and development to popularization, you also know how to do it. The roads we are currently building can last for a few years, so after the cement is produced, it is more appropriate to first apply it to river bridges, so that the travel time between cities can be reduced. , the economy will naturally accelerate.”
The phrase "If you want to get rich, build roads first" is not a joke in later generations. Only when business routes are opened up can the economy accelerate. The closed agricultural model of backwaters must be phased out quickly.
"You mentioned one problem, but what about the second one? I don't think the internal combustion engine is as difficult as you said. I think it is completely sufficient if it is self-produced and used at first."
"I'm not an expert on this issue, so I want to discuss it with you."
Rody is not self-willed, and expressed his own judgment: "We are too short on time. I am afraid it will take a long time to realize the use of mature internal combustion engines for trains. The difficulty of research and development and fuel issues are the key points, and I The reason for choosing a steam engine is that there are two large open-pit coal mines in Efta. For trains and ships, the technical difficulty of steam engine loading is much lower than that of internal combustion engines, and I remember that steam engines are very simple to operate and easy to maintain...so Do you think it is reliable to use a steam engine?"
Roddy knows that there are many types of internal combustion engines, and he also knows the principle of the piston’s power stroke, but it’s the same thing. He is completely blind to the angle of the crankshaft and how to do the cylinder—but Kardashian is different. She has read this information. It may not be impossible for the amazing dragon family in memory to want to copy a modern car engine.
However, the industrial level of the Karen Kingdom is a huge gap. Maybe it will be fine in ten years, but now...
Kardashian thought about it, unless she can make a group of dragons work as workshop workers, one by one taking into account stamping casting and processing technology...or there will be no reliable internal combustion engine at all. As for oil-opening oil wells and refining things, I have no experience.
Although with the help of magic, it will definitely not be as difficult as the research on the earth, but the problem is indeed as Rody said: there is too little time.
"As for the steam engine... I saw some structural diagrams at the time, and it seems to be the kind used on trains." Kardashian's memory is unquestionable, she nodded: "If there are enough coal mines, steam engines do have advantages on trains and ships , so that there will indeed be a lot of spar left..."
"Yes, in fact, we are already jumping the development of the technology tree. After all, the problem of eating enough for ordinary people has not yet been solved. The contradictions of the agricultural society lie..."
"Okay, okay, you can think about these things, and I can execute them." Although Kardashian has lost her identity as a dragon, she will not think from the position of ordinary people: "The Department of Agricultural Research There are already results, and we will start to try it in the spring—here, tell me which mines still need to be mined, list them in order, and I will arrange them.”
"Well, I'll write a list later."
Roddy paused for a moment, then suddenly said: "The internal combustion engine, can you still remember?"
"I've seen the cutaway diagram of a four-cylinder engine for a car, and the gas turbine only knows the principle, but the precision required for that thing is too high..."
There are many types of internal combustion engines. The most common one is the piston car engine, but the gas turbine is used in ships and aircrafts. The principle is similar, but the structure is very different. Kardashian's head popped up the materials comparing the engine structure, and her eyes lit up instantly: "You mean...the internal combustion engine should also be used?"
Rody glanced left and right, raised his hand and cast a spell to close the door and released the sound-proof barrier: "The high elves have such a powerful spar civilization, but they were wiped out by simple-minded guys like orcs. I guess it's probably because of the key. Time magic doesn't work...not even hedrons."
This speculation has actually been partly confirmed. It is no problem for Rody to use the spar to fight the unification war. What if the enemy is replaced by a demon? What if he was forbidden magic like the high elves
Of course, Kardashian has thought about these things, and now that Roddy said this, she narrowed her eyes: "Then...is it just the development of gas turbines and steam engines?"
"There are never too many means to deal with the enemy."
Rody turned off the projected map and answered in a low voice.
Kardashian didn't speak when she heard the words, but there was an inexplicable excitement in her eyes.
That night, Rody met Rahiman's envoy Mislan again, and after discussing, he said that "Karen Kingdom will support your country as quickly as possible", and then signed an agreement on the debt issue of the original loan—the most important It is the conditions for the Kingdom of Karen to intervene in the war in the form of "mercenaries" in exchange for debt forgiveness.
The Rahiman Council is arguing endlessly over the amount of debt relief, because "mercenary troops" have never fought against the Rahiman Sea ruled by mages, and ordinary mercenaries are not at the same level as the elite of the Karen Kingdom, so the cost It is always difficult to define—in the end, the agreement sets the ultimate goal of "successfully quelling the war within one year". If it is fully achieved, 60% of the debt will be forgiven, the repayment period will be extended for two years and the interest will be reduced.
In addition, except for the resources in Rahiman's land during the war, all other harvests belong to the Kingdom of Karen.
The agreement requires that Roddy's army must arrive at Lahiman within four months—because usually wars require a conscription period, from the kingdom to assemble the army, and then the army will go to the port to arrive at Lahiman by boat, three months before and after. .
Roddy agreed to this agreement after going back and forth with some conditions. He also understood that it was unrealistic to directly cancel all debts, no matter how many conditions he negotiated... Firstly, the employment fee cannot be so high, and secondly, It's a political game.
What the Kingdom of Karen needs more now is other things - Needless to say, all kinds of resources and population, the "trophy" clause is the reason why Rody is so excited.
From Houdini and Eveli, he learned that there are actually many rich countries and lands in the northern region of the Rahiman Kingdom. And as a mage-parliamentary country established to overthrow religious countries, they have always adopted a policy of supporting small countries to fight against Iscar... they have not leveled these countries one by one, so if Roddy's army is strong enough, the spoils of war will definitely be indispensable.
After the agreement was signed, Roddy sent the relieved Ambassador Mislan away. And he glanced at the dark night, and stepped to the top of the magic tower.
