The correct way to open the elf

Chapter 379 Magic Resistance Fortress
"E=mc2. Energy equals mass times the speed of light squared. This is something I wrote casually in my physics textbook. Do you know what this formula represents?"

"Mass equation, what does the energy band represent?"

Feng Yu smiled and said, "Yeah, what can it represent?

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

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

"It's far superior to forbidden spells. It's equivalent to the method of using forbidden spells. In other words, if you master it, you can use the forbidden spells we have."

Cromwell said: "If you want to use forbidden spells, you must at least have a magic rank that matches it. Even if a magic apprentice knows how to use forbidden spells, he can't use them!"

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

"You are such a bad boy. You tricked me into studying advanced mathematics. Now I feel like my magic isn't running smoothly."

Feng Yu smiled and said, "Don't be ungrateful. Go ask. Anthony and Demps are also studying advanced mathematics. Am I fooling them too?!"

"You are not trying to trick me, but you have bad intentions. I understand now. Advanced mathematics is like a forbidden spell. Not every magician can learn it. Even if they learn it, it is useless."

"You are right and wrong. Advanced mathematics is indeed not something that everyone can learn because it is too obscure and profound. But you can't say 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 large amount of mathematical knowledge is like holding a handy divine staff for the study of other sciences.

Forget it, let’s not talk about this anymore.

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

The magicians have completed the first section of steel bar welding work and have withdrawn from the construction site.

At this time, the prepared concrete, that is, the stone powder of the Green World, is also ready.

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

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

“It’s not really a secret. This stone powder was invented by the dwarves who mined in the mountains. The dwarves’ royal city was built with this stuff, but they used this stone powder instead of big stones.

We have something similar there, but it's used in a more daring way.

We first made the corresponding wooden mold. In order to make this project fast and strong, the mold was replaced by a steel plate directly welded 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 whole 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 stone powder will not break. "

Cromwell was shocked: "So whether it's here or in the buildings in Cattail City, a lot of high-quality steel is used inside? And this steel is sealed inside and can't be taken out from now on?"

"Uh, that's true!"

"Isn't this too luxurious?"

"It's not bad. There are large iron and steel veins in the Great Wasteland and the Snowy Mountains. Otherwise, we really can't afford all this trouble."

Cromwell said in surprise: "In the face of your weapons 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. Do they really need to be this thick? "

Feng Yu pointed to the steel plates that replaced the wooden molds and said, "See those little bumps on them?"

"What's the point of that?"

"That's a reserved welding point. Once we get the magic-hating iron, we'll use it to refine steel plates, and weld a layer of magic-hating steel plates on top of the ordinary hard steel plates."

Cromwell sneered and said, "Don't even think about it. The Brocade Empire will never sell you its magic-hating iron."

"Who said I was going to buy it in Brocade Empire?"

Cromwell said in surprise: "You found the Demon-hating Iron Ore Vein in the Great Wasteland? This is really a treasure land!"

"I would like to, but unfortunately it is not available. However, we have found a seller and have already established a connection with him. It won't be long before we have the magic-repelling iron to use."

"Where did you get it? A mermaid?"

"From the orcs in the Frostwind Grasslands. Thanks to those extremely bored top magicians of the elves, it is because of their reckless squandering of their long lives to travel the continent that I was able to learn such precious news."

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

"This is the only way for the initial stage. As for the future, we will find a way to process the magic-hating iron into iron ingots at its place of origin and then ship it back."

Cromwell pursed his lips. He was about to make a sarcastic remark, but then he remembered that the person who said this was the guy who built Cattail City, so he took back the words.

The Mage Saint couldn't help but believe it, because every one of the things this kid did was considered miraculous to Green.

"Super Fortress, Anti-Magic Iron Surface, it seems that the bones of the underworld are having some headaches. No wonder you dare to swear that you have a way to deal with the plane gate of the underworld."

"If they dare to show up near my home, they must be prepared to pay the price."

Cromwell smiled and said, "You, a foreign boy, are more confident in winning the Plane War than us natives!"

"That's because your eyes are always fixed on this little piece of land of Green.

If you don’t think about the future, you will have immediate worries. Planar war is Grion’s ‘immediate worry’.”

Cromwell smiled and said, "Why, where are you looking?"

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

"Are you serious?"

"What else?" Feng Yu asked back.

"Let alone the sea of ​​stars, even the sky is beyond your imagination." Cromwell looked like an experienced person.

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

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 restricts their imagination of magic.

Cromwell looked at the indifference on Feng Yu's face, and suddenly he became flustered.

"Could it be true?"
