The correct way to open the sprite

After returning to the camp, Feng Yu took Allen to wash and dry the snake fruit, then mashed it. Since there was no sugar, he added some honey, mixed it well, and then sealed it in a jar.

"It will take about ten days. Call Dick then and we will try it together. If the snake fruit is similar to the grapes we have there, we will have to transplant the snake vines on a large scale in the future, otherwise we will not be able to satisfy Dick's appetite. "

"If I really do what you said, I won't have to use hard-earned grain to brew the current Agehao."

"Brother, what a good thing"

Allen rolled his eyes at Feng Yu and said: "It's the kind of wine we often drink. I know you dislike it. Aghao is brewed with grain husks, small potatoes and other things to save grain, so It’s not very tasty, but it’s still intoxicating, at least the dwarves won’t dislike it.”

Feng Yu nodded, thinking that swill wine had such a weird name.

"Brother Darren, are you a very big noble in your place?"

Feng Yu asked without understanding: "Why do you say that?"

Allen scratched his head and said, "I see that you are very meticulous in what you eat, drink and use. You don't look like an ordinary child at first glance."

Feng Yu shook his head and said: "I grew up in an orphanage when I was a child. An orphanage is a place that specially adopts children without parents. I don't even have parents. How can I be a child of a noble family?

When I was young, in order to earn a living, I worked in salt fields, hotels, restaurants, and many other jobs. It was not until later that I understood the importance of knowledge, so I studied on my own, and eventually became a A craftsman who can make a lot of money.

In terms of the Greenland continent, you can understand that an unwanted child became a great mage through his own efforts. "

Allen said in surprise: "Is it the knowledge of those machines you made?"

Feng Yu shook his head and said: "These things are only elementary. The kind of things I study can't be made yet. Fortunately, I also know some elementary knowledge, otherwise it would be a joke."

"It turns out that your position is equivalent to that of our great sage. No wonder you can create so many magical things.

Brother Darren, there’s something I want to say”

"Alan, you were the first person I met when I came to the camp. It was you who introduced me to Dick and others and helped me integrate into the camp. Besides, even without those, we are still brothers now. What's the matter? Just say it, as long as I can do it."

Allen was moved and said: "Darren, my good brother, thank you. I just want our halfling children to learn from you, is that okay?"

Feng Yu patted Allen on the shoulder and said, "Why not? Even if you don't tell me, I will talk to you after a while and ask you to introduce halfling children to learn from me."

"Really, that's great. You know, not many of us halflings have magical talents."

Feng Yu smiled and said: "Do you know why I teach the children of the elves?"

Allen shook his head. They all thought that Feng Yu taught the elf children knowledge because of Nicole, but Allen was not stupid, how could he say it directly in front of Feng Yu.

"Because elves have long lifespans, their children are generally older, very sensible, and can read, so it will be easy for me to teach them. If I teach them, they can teach more children.

Haven't you noticed that I have now started giving lectures to my students? I also teach manufacturing techniques to students and some craftsmen, and then let them teach more people.

Knowledge is priceless, but as you can see, knowledge is different from magic. It is not a matter of one person. It requires the unity and cooperation of people who know all kinds of knowledge.

Therefore, I will definitely teach everyone my knowledge. You don’t have to worry about this. Anyone who is willing to learn can come and learn with me. "

Allen said happily: "That's great. You don't know that in the Green Continent, whether it is magic knowledge or other knowledge, it is very valuable. If you want to learn, you must not only be approved by the instructor, but also There will also be a rigorous apprenticeship ceremony, and you will have to serve the teacher for the rest of your life."

"This is a problem of ideas. The reason why the progress of the Green Continent is so slow. My hometown is different. We will spread the knowledge and let all those who are interested and capable to study it and create new ones. Knowledge.

Let me tell you a little secret. We have more than [-] million people with advanced knowledge.

So don't worry, just send someone to learn, as long as you are interested. "

Allen froze in surprise, frightened by the number of [-] million mentioned by Feng Yu.

Just one Darren turned the camp upside down and created so many magical machines and weapons. How powerful would their country with [-] million high-level knowledge talents become?

Feng Yu wasn't lying about this. The total number of college graduates there has already exceeded [-] million.

In the end, the steam water pump failed to use the screw pumping structure that Feng Yu came up with. He made a mistake that he took for granted.

Theoretically speaking, the screw water pump can indeed transport water to the wasteland with a drop of more than 20 meters from the river bank. However, when Feng Yu asked the students to calculate how long the slope flume needed to be built through the Pythagorean theorem, he discovered a serious problem.

Friends who have a certain understanding of steel, or have twisted steel bars on construction sites, must know that once steel reaches a certain length, it is no different from noodles.

If a wrist-thick steel bar is only one meter long, it can be used as a crowbar. You will never be able to bend it solely by manpower. But if the wrist-thick crowbar is 30 meters long, then you only need to bend it. With one end of it fixed, you can easily bend it by moving the other end.

Feng Yu wanted to make a screw with a length of more than 20 meters. This thing was impossible to use. The screw pumping device he saw in reality was less than ten meters long.

Fortunately, the sink hasn't been repaired yet, otherwise this man would be in trouble.

But now with the help of an alchemist, Feng Yu can design a larger, better-sealed steam engine and a more precise ordinary water pump. As long as the copper plate is bent and welded, a sealed copper water pipe can be made. The problem of pumping water is solved.

Such a well-sealed water pump that pumps water through water pipes, driven by a specially made large steam engine and variable speed gear, can pump water at high speed much more efficiently than a screw water pump.
