As soon as Galileo and Bruno saw Duke, he said in an extremely excited tone: "My lord, I have successfully developed the thermometer you asked me to develop!

"Very good Galileo, you really deserve the title of the founder of modern science!"

Duke praised him sincerely, sure enough, a cow is a cow, even if the world is different, the level that should be played is still played, he didn't expect the thermometer to succeed so quickly. At the same time, Galileo's scientific literacy also made Duke full of confidence in hydraulic transformation!

But Galileo looked at him at a loss and asked, "My lord, what is the founder of modern science?"

Hearing this, Duke knew that he had leaked his mouth again, but fortunately they didn't understand what it meant, so he quickly changed the topic and said: "Galileo, Bruno, I called you two here this time, there is an important experiment that you need to find a way to complete, that is, to transform the existing hydraulic machinery to make them more efficient!"

Hearing Duke suddenly say this, it still made the two scientific pioneers a little dazed, and the lord's mind jumped too fast, he would actually pay attention to this.

"My lord, what do you need us to do?"

Although Galileo didn't understand what Duke wanted to do, what Duke had done during this time had made them have absolute trust in Duke.

"I need to make gears that match different sizes, and I can make them fit into each other, and then drive them through the gear ratio, so that I can make a breakthrough in the transmission efficiency of the waterwheel, do you understand?"

What Duke is talking about is the most basic gear transmission method in later generations, just like a bicycle, through the chain to drive different gears, pedal a circle and the wheel can be turned several times, if you change to smaller gears, dozens of times are possible.

This is also the key to the development of water power in ancient China on the earth, which was left far behind by later Europe. When China's water cone is still slowly smashing rice with a wooden hammer, the hammer forged by hydraulic power has begun to touch the threshold of industrialization, and it is no wonder that this efficiency of hundreds of times is not lagging behind. At the same time, the change of hydraulic transmission mode is also the basis of the industrial revolution in the future, after all, even if the later generations enter the electric age, the transmission mode is still the same.

It's just that Duke didn't graduate from engineering machinery after all, and he didn't know what to call these things in the European world, so he could only describe them in the modern language of later generations, and then only Galileo himself understood. That's why he called Galileo, if you were an ordinary person, you really wouldn't want to understand what you were saying.

However, in Duke's memory, gears had already been invented, and even in medieval clocks and watches used gear sets, Galileo and they probably understood what they were saying, right?

It's just that after seeing the blank expressions on the faces of Galileo and Bruno, Duke understands that he is playing the piano to a cow, which is almost a communication between people in two worlds, how can they understand what they want to express?

Just when Duke felt extremely painful and didn't know how to describe his thoughts in the words of this world, Bruno suddenly asked tentatively: "My lord, are you talking about transmissions?"

Duke was stunned when he heard Bruno say the word transmission, and this set of gear combinations is actually commonly known as transmission. It's just that how did Bruno know such a thing as a transmission, which is completely beyond the product of the current scientific and technological civilization, could it be that the pioneers of medieval science were also time-travelers?

"That's right, it's the transmission, Bruno, how do you know?"

"I once met a goblin scholar whose steam engine looks like it used gears, and I feel that what you described, my lord, is very similar to the transmission that the goblin scholar said. ”

If Duke was just surprised before, now Duke doesn't know what to use to describe his mood at the moment.

Damn! This world not only has a transmission, but also steam power, which means that his previous assessment of the world's scientific and technological level is all wrong! But there is one thing Duke is very puzzled, then why Storm Castle is still so primitive, and even in memory, the French Emperor has not appeared any steam technology products, which seems very unreasonable.

"Bruno, where is the goblin scholar, can you find him?"

Duke hurriedly asked, if he really finds this so-called goblin scholar, then he will directly enter the stage of the first scientific and technological revolution, although the steam age is not very good in the future, but the efficiency can beat the current productivity! It is no exaggeration to say that the industrial age is not the same level as the agricultural age.

"I'm sorry Lord, but I can't find this knowledgeable goblin scholar, he may have been hidden in the depths of the Dark Forest. You should know that the thousand-year-old war of the five races has made humans and other races a feud, and it is already a coincidence that I was able to meet the goblin scholar, and it is impossible for him to stay in human territory for a long time. ”

Hearing Bruno say this, Duke instantly felt a sense of disappointment, although he didn't remember goblin technology. But he is still clear about the battle of the five tribes, and it should be said that there are very few people on this continent who do not know this period of history.

Originally, the most fertile area of the Europa continent cohabited five main races, namely humans, dwarves, elves, orcs, and sea tribes. However, as the population began to increase, especially the fertility and strength of human beings, all races began to fight for their own living space.

The end result was that the five races fought for hundreds of years, and finally a thousand years ago, under the leadership of the Holy See Knights and Mages, humans became the masters of this fertile continent. The other four races have basically taken refuge in some dangerous and unknown remote areas, and at the same time, hundreds of years of fighting have also made the five races a feud, and there is almost no contact, so it is difficult to meet other races, let alone find goblin scholars.

Seeing the disappointed expression on Duke's face, Bruno continued to add at this time: "Lord Lord, although I can't find a goblin scholar, but I have done some research on his steam engine at the beginning, and I think I should be able to make a similar transmission." ”
