The correct way to open the sprite

Chapter 379 Magic Resistance Fortress
"E=mc2, energy equals mass multiplied by the square of the speed of light, this is something I wrote down in my physics textbook, do you know what this formula means?"

"Mass equation, what does energy mean?"

Feng Yu smiled: "Yeah, what can it represent?

You see, I casually wrote the ultimate forbidden curse of our world into a book that everyone can read, so no one will pay attention to it. "

"Forbidden curse?" Cromwell was very sensitive to this word.

"Far beyond the forbidden spell, it is equivalent to the method of using the forbidden spell. In other words, if you master it, you can use our forbidden spell."

Cromwell said: "If you want to use the forbidden spell, you must at least have a matching magic rank. Even if the magic apprentice knows how to use the forbidden spell, he still can't use it!"

"That's right, but I just want to tell you that I didn't lie to you, it's just that you don't believe it yourself, so you can't blame me."

"You kid is very bad. You lied to me to learn advanced mathematics. Now I feel that my magic power is not running smoothly."

Feng Yu said with a smile: "Don't be ignorant of good people, you go ask, Anthony and Dempsey are also studying advanced mathematics, am I fooling them too?!"

"You are not fooling around, but evil-hearted. I understand that advanced mathematics is like a forbidden curse. Not all magicians can learn it. Even if you learn it, it is useless."

"Whether you are correct or not, advanced mathematics is indeed not something that everyone can learn, because it is too obscure and profound. But it must not be said that it is useless.

After all, science is not magic. Learning forbidden spells is indeed useless for magic apprentices, but learning advanced mathematics is very useful.

Because mathematics is the foundation of science, mastering a lot of mathematical knowledge is like mastering a god-level staff in hand for other scientific research.

Forget it, let's not talk about it.

You see, the most important pouring job is about to start. "

The magicians have completed the welding of steel bars in the first section and have withdrawn from the construction site.

At this time, the concrete that had been prepared, that is, the stone powder of Grian's world, was also ready.

After a brief and rough inspection of the steel structure, the concrete began to be poured into the steel structure.

"Is this the secret of the tall buildings in Cattail City?" Cromwell asked.

"It's not really a secret. This kind of stone powder was invented by the dwarves who started mining in the mountains. The dwarves' royal city was built with this kind of thing, but they used this kind of stone powder instead of big stones.

And we have similar things there, but the usage is more daring.

We first made the corresponding wooden molds. This project was fast and strong, so the molds were replaced by steel plates welded directly outside the steel structure.

In this way, after the stone powder poured into the mold dries, it will become a huge whole, as if it was dug out of a complete big stone.

But you know, stones are very hard, but they are also very brittle, and the steel bars inside greatly strengthen the toughness of this kind of stone powder building, so that the stones made of these stone powders will not be broken. "

Cromwell was stunned: "So whether it is here or the various buildings in Cattail City, a lot of high-quality steel is used inside? And these steels have been sealed inside since then, so they can't be taken out?"

"Uh, that's true!"

"Isn't this too extravagant?"

"It's not too bad. There are steel veins with large reserves in the Great Wasteland and the Xueding Mountains. Otherwise, I really can't support such a toss."

Cromwell said in surprise: "In the face of your weapon attack, I really can't think of anyone who can destroy this kind of fortress.

My God, the foundation is nearly two meters deep, and the thickness of the walls on both sides is more than one meter. Is it really necessary to be so thick? "

Feng Yu pointed to the steel plates that replaced the wooden formwork and said, "See those little protrusions on it?"

"Then what's the name?"

"That's the reserved welding point. When we get the Devil's Iron, we'll use the Devil's Iron to make a steel plate, and weld a layer of Devil's Steel on top of the ordinary hard steel plate."

Cromwell sneered: "You don't even have to think about it, the Brocade Empire's Devil-hating Iron will never be sold to you."

"Who said I would buy it in the Tapestry Empire."

Cromwell said in surprise: "Did you find the demon-hating iron veins in the Great Wasteland? This is really a treasure land!"

"I would like to, but it's a pity that there is no such thing, but we have found a seller, and we have already caught up with it. It won't be long before we have the magic-hating iron that we can use."

"Where did you get it? A mermaid?"

"The orcs in the Cold Wind Grassland. Thanks to those extremely boring top magicians of the elves. It is precisely because they recklessly squandered their long lives and traveled the continent that I learned such precious news."

"You don't want to use the big kun to transport the heavy demon-hating iron, do you?"

"In the early days, this is the only way to go. As for the future, we will find a way to process the demon-hating iron into iron ingots at the original place and then transport them back."

Cromwell pursed his lips. Just as he was about to say something sarcastic, he realized that the guy who said this was the kid who built Cattail City with one hand, and took back the words that came to his lips.

Fa Sheng couldn't help but believe it, because the series of things this kid did, all of them were considered miraculous in Gryen's eyes.

"Super fortress, devil-hating iron surface, it seems that the bones of the underworld are having a headache. No wonder you dare to swear that there is a way to deal with the gate of the underworld."

"If they dare to appear near my house, they must have the awareness to pay the price."

Cromwell said with a smile: "You foreign boy, you are more confident in winning the war of planes than us natives!"

"That's because your eyes are always on Grian's three-acre land.

People without thought, he must worry about.Plane war is Grynn's 'near worry'. "

Cromwell said with a smile: "Why, where is your kid looking?"

"Our journey has never changed, that is the sea of ​​stars!"

"Are you serious?"

"Otherwise?" Feng Yu asked back.

"Don't talk about the stars and the sea, even the high sky is beyond your imagination." Cromwell looked like someone who had come here.

Feng Yu wanted to laugh, but he didn't say anything in the end, but he felt that the so-called magical power was just a little more magical, that's all.

This is not to say that the magic power is not strong enough, but that these casters have limited vision, and their vision limits their imagination of magic.

Looking at the indifference on Feng Yu's face, Cromwell suddenly became flustered.

"Could it be true?"
