Datang: At the beginning, I wanted to rebel against my father-in-law

Chapter 242 Four or two moves!
"Find a rope and a pulley!" Su Feng immediately turned around and saw Zhao Feng and said.

For people in this era, four or two thousand catties is just a legendary existence, or it is theoretically feasible.

but.

It's completely different for Su Feng!

This is the case in this era. Just relying on some common sense of later generations can change many problems, especially the very practical knowledge of physics. If you use it well, you can have earth-shaking changes.

"What is a pulley?" Zhao Feng quickly asked someone to find a rope, but he didn't understand what Su Fang said about the pulley at all, he only knew that it should be a kind of wheel.

But there are many types of wheels, and the sizes and specifications are completely different. If there is a difference, the effect will be different. What's more, he has no concept of this aspect at all.

Not only Zhao Feng, but also Changsun Wuji and others who were watching looked at Su Feng curiously. It has been rare for so long to hear Su Feng say new terms.

Especially Changsun Wuji...

In terms of machinery, Su Feng taught him a lot of knowledge. According to past experience, if Su Feng said something that everyone couldn't understand, it meant that he would come up with something shocking.

"I'll draw a simple sketch for you. You may not be able to do it right now. You can easily make it out of wood!"

"Although there may be some problems with the quality, it can be used in an emergency for the time being. If you become proficient in the future, you just need to make it out of steel step by step!" Su Feng said thoughtfully.

soon.

Zhao Feng put the pen and paper in front of Su Feng himself, and under everyone's concerned eyes, Su Feng simply drew the manufacturing method of the pulley.

This is not a very complicated thing. Even ordinary craftsmen can make it very easily as long as they see their own structure diagram.

Zhao Feng was obviously disappointed!

He also thought that the things Su Feng was working with would be complicated, and that's what they thought, the more complicated things were, the better.

Things that can be made so easily, even if they are useful, are not that big.

of course.

These are just some thoughts in Zhao Feng's mind, and nothing abnormal can be seen on the surface. After Su Feng finished drawing a manufacturing drawing, he took it without any hesitation and went to make it first.

When Zhao Feng was taking the blueprint to make the pulley, Su Feng turned his head and looked at Changsun Wuji, Li Chengqian, and Li Jing with a smile.

"You have also seen the materials here. Each one weighs at least seven or eight hundred kilograms, and I only need a rope and a pulley to transport it away with ease!"

"And it's not just me, any ordinary person can do it easily, and the whole process only takes a short time!" Su Feng raised his eyebrows and said, looking at everyone with deep meaning.

As soon as his words fell, everyone immediately fell silent, and most of them set their eyes on the huge steel.

then.

Recalling what Su Feng said just now, there is always a feeling of unreality.

Although they have seen Su Feng's various abilities, the weight of these materials is in front of them. If a machine as huge as a train is used, it may be understandable that one person can carry it.

But according to what Su Feng said, it can be done easily with just a rope or a pulley. This is really unbelievable.

Even if it's four ounces and a thousand pounds, it won't be so exaggerated, right?
Changsun Wuji, who has always been obsessed with mechanical knowledge, did not express any opinion on this, but suppressed his doubts in his heart.

In this regard, he has followed Su Feng for the longest time, knowing that the other party will not say such things casually, no matter how unbelievable the thing is, it may happen.

But people like Li Chengqian and Li Jing are completely different!

They only want to believe the facts they see. The weight of the materials here is real, and even a dozen people may not be able to move it easily.

With such a simple tool, it is impossible for one person to carry it away, even if it is moved a little.

Looking at the very casual smile on Su Feng's face, they instinctively thought that this might be Su Feng joking with them, and it was also to ease the current embarrassing atmosphere.

"My lord really shouldn't be joking at this time. All the workers here are watching. If after a while the pulley is made, it is impossible to do what he said, then today..." Li Jing lowered his voice and looked at the side. Li Chengqian whispered.

Just look at their current performance as a worker to understand that Su Feng's words have set off a huge wave in their hearts, and many people are constantly rubbing their hands and looking forward to the next thing.

If Su Feng can't finish today, or if he just played

If a joke is defined as bragging, then his prestige in the hearts of everyone will be greatly reduced in the future.

This is the case with many things. For things that have been maintained for a long time, even if you do something that does not match it, all the previous efforts will be in vain.

"It's really a bit reckless..." Li Chengqian shook his head slowly.

At this time, as the prince, it was hard for him to say anything, not to mention, almost all of what Su Feng said before had become true.

All they can do now is to wait silently until Su Feng proves it with facts. If it is really not over in the end, Li Chengqian and others are also ready to use their identities and status to smooth things over for him.

Not long after, Zhao Feng came back with this good pulley under everyone's expectant eyes.

As Su Feng said before, time is running out now, so he only used the best wood to carve several pulleys, just to prove Su Feng's method.

When the pulleys and ropes were placed in front of Su Feng, the look of anticipation on everyone's faces became more intense. They all wanted to know whether what Su Feng said before was true.

Especially the workers who carry steel every day, if everything Su Feng said is true, it will bring them great convenience.

From now on, I no longer need to spend most of my energy on moving materials every day, and I have time to do more things.

"Next, I will demonstrate to you what physical power is!" Su Feng said after taking a deep breath and looking at everyone around him.

His words were mainly for Changsun Wuji, Li Chengqian and others to listen. After all, they all learned physics-related knowledge in the Science Department.

Now is the time for them to open their eyes and really understand the benefits.

then.

Su Feng quickly fixed the rope and the pulley according to his unique method, and finally tied them to a steel rail...
