Demon King, Don’t Run Away Chapter 650: I tell you, physics changes life

After finishing the conversation with the Luhua Army, Dong Mu looked at the towering city wall not far away.

Without any preparation, if you want to rush from here to Fengmang area quickly, the towering city wall in front of you is the most troublesome.

Leave aside the climbing abilities of Yang Yu and the striped gecko clan, the other orcs with sharp teeth and claws have no ability to climb over this towering city wall.

The city wall built by humans is nearly thirty meters high and can accommodate ten carriages running in parallel. It is made of large square stones. It is simply a fantasy to open a big hole in the wall.

This can also be seen from the side, how incredible it is that the wall on the eastern front collapsed.

Goddess of Luck is very busy and has no time to help them kick on the city wall.

There is a long, long distance from here to the open central area. Going around this city wall will probably take a lot of time and delay rescue.

What should we do?

Longmu himself is not a very good thinking general, but fortunately he is willing to listen to other people's ideas and suggestions.

He has always believed that when encountering a problem, only by thinking together can we find the solution the fastest.

As a matter of course, Dong Mu summoned all the officers and held a meeting to brainstorm ideas.

Some people say that a siege ladder can be used, but unfortunately the ladder is still too short facing the towering wall.

Some people say that tunnels can be dug, but this is also a very time-consuming method. After all, humans laid a very deep foundation when building this city wall.

Some people say that you can use magic to build ice stairs. In this kind of weather, ice stairs are not easy to build. However, given the height of the wall, the amount of ice required to build the ice stairs is orders of magnitude. All magicians add up. It may take several days and nights to complete, but there is no chance it will be completed.

Many of the plans proposed in succession were rejected by Dong Mu.

But he still kept a few that looked reliable and would use them when there was really no other way.

Yang Yu always felt that this kind of work that required transporting people to high places was a bit familiar. Only later did he remember, isn't this an elevator?

It is a pity that building an elevator here is tantamount to wishful thinking.

It would be great if the soldiers could be packed away...

In Yang Yu's world, there are also props that can easily lift heavy objects to high places, such as cranes.

It would be nice to have a station.

But Yang Yu felt that something like a crane must be an epic or above-level item. It would be extremely difficult to get it in the vast prize pool.

What’s even more difficult is that I don’t even know if there is such a thing in the prize pool.

Even if there is one, it doesn't have to be a crane, a breaker or a shield machine used to dig caves.

It is not right to just open a big hole in this city wall and let the Luo Ze Empire repair it, nor is it not to repair it.

To be more simple and crude, you can just take a bunch of explosives and blow up the wall.

Good or good, the problem is that we can only think about it.

In Yang Yu's system, those excessive things cannot be found yet.

However, when it comes to cranes and elevators, Yang Yu has come up with a solution.

Although there are no high-end products such as cranes, shield machines, breakers, and excavators, there are still a few physics textbooks.

Yang Yu remembered that when he was chasing fans, he had seen someone using a pulley block to lift a large tree that was several times heavier than himself.

If you can find the chapter about pulleys and review it carefully, maybe you can find a solution.

Unable to do anything else, Yang Yu quickly made up a random reason, left the scene immediately, and found a place to look through books to find the answer.

Yang Yu entered the lottery many times, and before he knew it, he had collected a complete set of physics textbooks from junior high school to university. The words x2 and x3 even appeared in the upper right corner of the books.

The hard work paid off. Yang Yu found the chapter about the pulley without much effort, reviewed it carefully, and gradually constructed the best plan in his mind to help the army climb the wall.

......

......

In the camp, Dong Mu listened to one suggestion after another, but still couldn't find the right one, so he shook his head secretly.

At this moment, Yang Yu ran back with a piece of paper,

"General, I have a great idea, here is the design."

As soon as he heard that Yang Yu had a solution, Dong Mu took the design drawing from Yang Yu's hand and took a look, Huo, what is this drawing? These lines are twisted and twisted, and I have no idea what the drawing is. thing.

Long Mu looked at Yang Yu's paintings and then at Yang Yu, not knowing how to evaluate them.

"It's normal that the general can't understand. I've lived in the human world for a while. Please wait for me, general. I'll find someone to make a sample and I'll be back soon!"

After saying that, Yang Yu completely disappeared from the tent.

Dongmu sat in the tent, folding his hands and tapping his arms with his index finger. About half an hour later, Yang Yu ran back in a hurry, carrying a white model in his hand.

Except for the strings, whether it is the pulleys, brackets, or the ice surface representing the city wall, the rest is made of ice.

Yes, Yang Yu asked Bai Jin to make small parts for this model, and then built it himself.

The ice created by ice magic can create ice cubes of various shapes as long as the direction of the magic is controlled before releasing the magic.

Not to mention the common summer-repelling square ice, it is easy to create a spherical shape, and other shapes are not impossible.

It is said that there once was a powerful and perverted ice magician who liked to use ice to carve the girls he saw. He could also make the ice move to serve him. He used ice magic to build a palace in an extremely cold place. , enjoy your wonderful harem life.

As a result, he forgot to cover himself with a quilt and was frozen to death by his own ice sculpture.

Making these little gadgets like pulleys is much easier than making ice sculptures. Of course Bai Jin can make them.

Just...

Bai Jin didn't know what Yang Yu was talking about at first, nor how to make what Yang Yu asked her to make, until Yang Yu taught her what three views are, and took out a compass and ruler to make each part. three views.

After leaving the library, Bai Jin was no longer as impatient as before. She was able to calm down and follow the teachings taught by Li Yan and Ti Ke that "if you want to climb the peak of magic, you must be down-to-earth and have a solid foundation", and started over and over again. Lay your own foundation again and again.

Recently, Bai Jin's speed in learning magic has increased significantly, and she has become more and more aware of the mysteries of magic. After [Multiple Casting], she has vaguely grasped the key points of [Dance in the Sky] and [No Chanting]. The new Range attack magic is also being learned.

I heard that a real great magician never sticks to his own skills, but just picks up whatever magic he wants.

Bai Jin can see that Yang Yu is taking this adventure not only to survive from the devil...

His target is definitely the Demon King. As long as he can defeat the Demon King, there is no need to be afraid.

You must be the person who can stand by his side.

Since she did not miss any study during the war, it was not difficult for Bai Jin to make the gadgets Yang Yu requested. Each one was exquisite, beautiful and strong, just like a real piece of glass.

Thanks to Bai Jin, Dong Mu had a good impression of this model and stared at it with interest.

Yang Yu raised the corners of his mouth slightly and said:

"General, let me tell you now about the function, principle and usage of this thing. It is actually very simple."
