After finishing the conversation with Luhua Army, Dongmu looked at the towering city wall not far away.
If you want to quickly get to Fengmang area from here without any preparation, the towering city wall in front of you will be the most troublesome.
Not to mention Yang Yu and the striped gecko clan who have climbing abilities, the other beastmen with sharp teeth and claws have no ability to climb over this towering city wall.
The city wall built by humans is nearly 30 meters high and can accommodate ten carriages running in parallel. It is constructed of large square stones. It is simply a pipe dream to want to make a big hole in the wall.
This also shows from the side how incredible the collapse of the city wall on the eastern front was.
The goddess of luck is very busy and has no time to help them kick the city wall again.
There is a very long distance from here to the open central area. Going around this city wall will probably take a lot of time and delay the rescue.
What should we do
Dongmu himself is not a very thoughtful general, but fortunately he is willing to listen to other people's ideas and suggestions.
He has always believed that when encountering a problem, everyone can find a solution quickly by thinking together.
Dongmu naturally called all the officers to hold a meeting to brainstorm.
Some people said that siege ladders could be used, but unfortunately the ladders were too short compared to the towering walls.
Some people say that they can dig tunnels, but this is also a very time-consuming method. After all, humans laid a very deep foundation when building this wall.
Some people say that magic can be used to build an ice staircase. In this kind of weather, the ice staircase is not easy to melt. However, considering the height of the wall, the amount of ice needed to build the ice staircase is enormous. Even if all the magicians work together for several days and nights, it may not be completed.
Many plans proposed in succession were rejected by Dongmu.
But he still kept a few that looked reliable and would use them when he had no other choice.
Yang Yu always felt that this kind of work that required sending people to higher places was somewhat familiar. Later he remembered, isn’t this an elevator
Unfortunately, building an elevator here is just a pipe dream.
It would be nice if we could pack up the soldiers and take them 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 TV.
But Yang Yu felt that something like a crane must be an epic item, and it would be extremely difficult to get it from the vast prize pool.
What’s even more difficult is that you don’t even know if there is such a thing in the prize pool.
Even if there is one, it is not necessary to use a crane. A breaker or a tunnel boring machine will do.
Just make a big hole in the city wall, so that the Rose Empire can neither repair it nor not repair it.
To be more simple and brutal, you can just take a bunch of explosives and blow up the wall.
It’s good, but the problem is that it’s really just something we can only think about.
Yang Yu couldn’t find those excessive things in his system for the time being.
However, when it comes to cranes and elevators, Yang Yu came up with a solution.
Although there are no high-end goods such as cranes, tunnel boring machines, breakers and excavators, there are still a few physics textbooks.
Yang Yu remembered that when he was watching anime, he once saw someone use a pulley system to lift a tree that was several times heavier than itself.
If you can find the chapter about pulleys and review it carefully, you may be able to find a solution.
In order to go all out, Yang Yu quickly made up an excuse, left the scene immediately, and found a place to look for the answer in a book.
Yang Yu drew the lottery many times and unknowingly had collected a complete set of physics textbooks from junior high school to university. There were even words x2 and x3 appearing in the upper right corner of the books.
Hard work pays off. Yang Yu found the chapter about pulleys without much effort, reviewed it carefully, and gradually built up the best plan in his mind to help the army climb the wall.
In the tent, Dongmu listened to one suggestion after another, but still couldn't find a suitable one, and shook his head secretly.
At this moment, Yang Yu ran back with a piece of paper.
"General, I have a great idea. Here are the designs."
Upon hearing that Yang Yu had a solution, Dong Mu took the design drawing from Yang Yu's hand and took a look. Wow, what was this drawing like? The lines were all crooked and it was impossible to tell what was being drawn.
Dongmu looked at Yang Yu's painting, then looked at Yang Yu, not knowing what to say.
"It's normal that you don't understand. I once lived in the human world for a while. Please wait for me for a while. I'll find someone to make a sample and come back soon!"
After saying that, Yang Yu disappeared completely in the tent.
Dongmu sat in the tent, folded his hands, and tapped his arms with his index fingers. About half an hour later, Yang Yu came back in a hurry with a white model in his hand.
Except for the thin ropes, whether it is the pulleys, the brackets, or the ice surface representing the city wall, the rest is made of ice.
That’s right, Yang Yu asked Bai Jin to make small parts for this model, and then he built it himself.
The ice created by ice magic can be made into ice cubes of various shapes as long as the direction of the magic power is controlled before releasing the magic.
It goes without saying that the common ice cubes for cooling off the heat can be made into spherical shapes, and other shapes are not impossible.
It is said that there was once a powerful and perverted ice magician who liked to use ice to replicate the girls he saw. He could also make the ice move to serve him. He built a palace with ice magic in an extremely cold land and enjoyed his wonderful harem life.
As a result, he later forgot to cover himself with a blanket and was frozen to death by his own ice sculpture.
Making these little gadgets like pulleys is much simpler than making ice sculptures, so of course Bai Jin can make them.
only
At first, Bai Jin didn't know what Yang Yu was talking about, nor did she know how to make what Yang Yu asked her to make, until Yang Yu taught her what three views were, and then took out a compass and ruler to make three views of each part.
After leaving the library, Bai Jin was no longer as impatient as before. He was able to calm down and follow the teachings of Li Yan and Tiko, "If you want to reach the peak of magic, you must be down-to-earth and lay a solid foundation," and he laid a solid foundation over and over again from the beginning.
Recently, Bai Jin's speed in learning magic has increased significantly, and she has become more aware of the mysteries of magic. After learning [Multiple Casting], she has vaguely grasped the key points of [Air Dance] and [No Chanting], and is also learning new area attack magic.
I heard that a truly great magician is never restricted by his own skills, but can perform any kind of magic he wants.
Bai Jin could see that Yang Yu took this risk not only to survive the demon king.
His target must be the Demon King. As long as he can defeat the Demon King, there is no need to be nervous.
I must become the person who can stand beside him.
Since Bai Jin had not fallen behind in her studies during the war, it was not difficult for her to make the gadgets that Yang Yu requested. Each one was exquisite and beautiful, and had good strength, just like a real piece of glass.
Thanks to Bai Jin, Dongmu had a good impression of the model and stared at it with interest.
Yang Yu raised his mouth slightly and said:
"General, now let me tell you about the function, principle and usage of this thing. It is actually very simple."
