The correct way to open the sprite

"e2, energy is equal to mass multiplied by the square of the speed of light. This is something I casually wrote into my physics textbook. Do you know what this formula represents?"

"The mass equation, what does it mean?"

Feng Yu smiled: "Yeah, what does it mean?

You see, I casually wrote the ultimate forbidden curse of our world into a book that everyone can read, and no one will take it seriously. "

"Forbidden Curse" Cromwell was very sensitive to this word.

"It's far more than a forbidden spell. It's equivalent to how to use a forbidden spell. In other words, if you master it, you can use the forbidden spells we have."

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

"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. You can't blame me for that."

"You're a very bad boy. You tricked me into learning advanced mathematics. Now I feel like my magic power doesn't work smoothly."

Feng Yu said with a smile: "Don't you know the hearts of good people? Go and ask, Anthony and Dempsey are also studying advanced mathematics. Am I also deceiving them?"

"You are not cheating, but you are evil-minded. I understand that advanced mathematics is like a forbidden spell. Not all magicians can learn it. Even if you learn it, it is of no use."

"Whether you are right or not, advanced mathematics cannot be learned by everyone, because it is too obscure and profound. But it cannot be said that it is useless.

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

Because mathematics is the foundation of science, mastering a large amount of mathematical knowledge is like mastering a god-level staff for the study of other sciences.

Forget it, let's not talk about it.

You see, the most important pouring operation is about to begin. "

The magicians have completed the steel welding work in the first section and have withdrawn from the construction site.

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

After a brief and cursory inspection of the steel structure, concrete began to pour into the steel structure.

"Is this the secret to 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 dug mountains and mines. The dwarves' royal city was built with this kind of stuff, but they used this kind of stone powder to replace the big rocks.

And we have something similar there, but the usage is a little bolder.

We first made the corresponding wooden mold. In order to make this project fast and strong, the mold was replaced by a steel plate welded directly to the outside of the steel structure.

In this way, after the stone powder poured into the mold dries, it will become a huge whole, just like it was carved out of a complete large stone.

But you know, stones are very hard, but also very brittle, and the steel bars inside greatly enhance the toughness of this stone powder building, so that the stones made of dried stone powder will not break. "

Cromwell was stunned: "So whether it is here or in the various buildings in Cattail City, a large amount of high-quality steel is used inside, and this steel has been sealed inside since then and cannot be taken out."

"Well, that's true."

"This is too luxurious"

"It's not bad. There are large reserves of steel ore veins in the Great Wasteland and the Snow-capped Mountains. Otherwise, we really wouldn't be able to support such an effort."

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

Oh my god, the foundation is nearly two meters deep, and the walls on both sides are more than one meter thick. Do we really need this thickness?"

Feng Yu pointed to the steel plates that replaced the wooden molds and said, "Do you see those little protrusions on them?"

"What's the point of that?"

"Those are the reserved welding points. When we get the magic-hating iron, we will use the magic-hating iron to refine the steel plate, and then weld a layer of magic-hating steel plate on top of the ordinary hard steel plate."

Cromwell sneered: "You don't have to think about it. The Demonic Iron of the Brocade Empire will never be sold to you."

"Who said I wanted to buy it in Brocade Empire."

Cromwell said in surprise: "You have found a vein of Devil-weary iron ore in the wilderness. This is really a treasure land."

"I'd like to, but it's a pity that this doesn't exist. But we have found the seller and are already hooked up. It won't be long before we have the Demonic Iron to use."

“Where did you get the mermaid?”

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

"You don't want to use the Titanic Kun to transport heavy demon-throwing iron, do you?"

"This can only be done in the early stage. As for the future, we will find a way to process the demon-weary iron into iron ingots in the place of origin and then transport them back."

Cromwell pursed his lips. He was about to say something sarcastic, but he thought that the person who said these words was the boy who built Cattail City with his own hands, so he took back the words that came to his lips.

The Dharma Saint couldn't help but believe it, because all the series of things this kid had done were considered miraculous to Greg.

"Super fortress, the surface of the Demonic Iron, 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 show up near my home, they must pay the price."

Cromwell smiled and said: "You, a foreigner, are more confident in winning the plane war than us natives."

“That’s because your eyes have always stayed on this three-thirds of an acre of land called Gerien.

People without thought, he must worry about.Plane war is Grean's immediate concern. "

Cromwell smiled and said: "Why, where are your eyes?"

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

"Are you serious?"

"Otherwise" Feng Yu asked.

"Don't talk about the stars and the sea, even the high altitude is beyond your imagination." Cromwell looked like he had come before.

Feng Yu wanted to laugh, but in the end he didn't say anything, but he felt that the so-called magical power was just a bit magical, nothing more.

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

Seeing the indifference on Feng Yu's face, Cromwell suddenly became panicked.

"Is it really true?"
