Things From Another World

671. Chapter 669 is difficult to communicate with a girl

Dunn simply flipped through the documents that Fiona had compiled. In the past few days when he was not there, Fiona was not idle, and everything he had explained was well done.

“Well done well, the use of universal alloys is very extensive and must be produced in large quantities.”

After Dunn finished, he still feels a little regretful. If he is studying chemistry, physics, and materials on earth, he may be able to find a way to figure out what the elements of the ordinary steel are qualitatively changed. A certain element in the herb has become a catalyst for magical metal, so that the properties of the magic metal can be greatly improved with the ordinary steel. If you can understand it, you can find a way from the gray grass and the silver flower. Large-scale extraction of the corresponding elements directly synthesizes all-purpose alloys. How much more is the production efficiency improved?

Unfortunately, the courtiers can’t really do it…

Fiona shrugged and glanced at Dunn, then said with a blank expression: “The other one is that the results of the midterm exam have already come out. I think it is necessary to give you feedback on this matter. The problem is very big now.”

“Well? Not all of the exams were handed over to Pamela.”

“Because the students are very resistant to the exam… even because of the exam, the students are complaining about you.”

Fiona looked at Dunn with a strange look: “Eurly Ilia has complained to Miss Elsa several times.”

Dunn heard a smile: “What is the effect is to let them enjoy the fun slowly. I haven’t got a class and three years of college entrance examination for five years. They should be thankful.”

At the moment, Dunn is very boring. He intends to let the children who have endured the ignorance of these innocence and ignorance, and then be famous for saying that “the sky will be reduced to the people of Sri Lanka and must first suffer from their minds…”

Although Fiona didn’t understand what Dunn was saying, she knew that it was not a good thing. She spread her hand and said: “Ms. Pamela made a subtle decision based on the students’ grades and the direction of their good after the papers were revised. Course and class adjustment, she hopes to teach students in accordance with their aptitude, so that each student can master what they are best at.”

Dunn frowned: “Is it a bit early? They are just getting in touch with basic education, and they don’t see their talents. Basic education must be mandatory and complete acceptance.”

“You can go and talk to Ms. Pamela.”

“You help me tell her, I don’t have time.”

Dunn shook his head and took out some small things and threw them on the table: “The next few days, I have to study something… Yes, you can help me find Ottina, I am looking for her.”

Fiona looked at her and found that it was some small parts that were unclear and nodded and left.

“Deep sea torpedo… although it’s quite simple…”

Dunn stunned his head, and I am afraid that only he himself knows how big the problem is.

Power is not a problem. The problem lies in the resistance of deep-sea torpedoes to water pressure. Although the elliptical structure can effectively reduce water pressure, the deepest part of the abyss can reach four kilometers. The torpedo can withstand such a strong water pressure. It is a big problem.

In addition, there is a problem of magic energy signal transmission. In the deep sea, the concentration of water elements is quite large, and the interference is also very strong. The use of magical fluctuations to transmit control signals may be disturbed. The best choice is to use the ubiquitous water element in the deep sea. To achieve communication and control.

The most important part is how to stimulate the warhead.

The small parts on the table floated in front of Dunn, quickly combined into a mini torpedo. When he waved, there was a splash of water in the air, and then wrapped in a mini torpedo, Dunn began to pressurize.

When the pressure increased by about 50 times, the mini torpedo has undergone significant deformation, which indicates that the strength of the material is not enough to resist the next pressure.

Dunn’s brow wrinkles: “Sure enough, the single-layer structure is not working, it is only 50 times the pressure, only equivalent to the strength of a kilometer of water… then it is replaced by a two-layer composite structure.”

He recalled the material structure that he had seen on Earth. I remember that there is a double-layer pressure-resistant shell structure that adds lateral support rods (ribs) between the two partition walls, and then fills the interlayer with high-pressure gas to enhance the shell resistance. The compressive strength, thereby achieving a stepped pressure drop stress state.

He thought of doing it, and after diving the water polo, he immediately started making another mini torpedo.

It didn’t take long for Ottina to push the door: “Is there something?”

Dunn glanced at Ottina, and then he was shocked: “Are you doing this?”

Ottina’s silver hair is quite beautiful, it is as smooth and smooth as the satin under the moonlight, but at the moment her hair is full of weeds, even the clothes on her body are a bit dirty, like in the grass. It was a goddess, but this image was too ruined.

Ottina did not answer Dunn’s question, but repeated one sentence: “Is there something?”

“of course.”

Dunn pointed to the sofa: “Sit.”

After Otiniya sat down, Dunn gave her a cup of tea, took some homemade refreshments, and said, “I have a problem and want to use your strength to solve it.”

Otiniya just picked up a shortbread and prepared to bite it. The news immediately put it back in a vigilant manner: “What?”

“Hey, you eat, I am not using you to do bad things.”

Dunn was stunned by her vigilance, but Ottina did not respond at all, just looking at him straight, the girl’s deep eyes were full of vigilance.

“Well, then I will just say it.”

Dunn sighed and said: “A few days ago we went to the sea of ​​the abyss, solved a group of chaotic creatures near the broken archipelago, and an ancient deep sea warcraft called Leviathan, which was corroded by native chaotic organisms. And the original chaotic creature comes from the deep sea, the door of the abyss inside the wrath of the fisherman’s territory, now we want to close the door of this abyss.”

“You go to the sea?”

“Of course I can go to the sea, but that can’t solve any problems. Now I think of a way to use a carrier to send the astral crystals to the door of chaos.”

“Detonated?”

“Yes, it is the detonation of the astral crystal!”

Dunn slammed his finger and said: “The power of the star-shaped crystal explosion is quite impressive. It can directly destroy the space near the door of Chaos and completely destroy the door of Chaos. Well, although it will leave a little sequelae…”

Otiniya licked her hot tea and nodded: “It’s feasible.”

“I know it works, because when I was at sea I blew up a chaotic door.”

Dunn smiled and said: “The sky is still cracking now. If you can, help me fix it?”

With the power of Ottina, the efficiency of repairing space will be greatly improved. It takes a few legends to get things done in a month. The real gods may only need to make a single stroke to solve the problem.

“Is this the case?”

“It’s really hard for you to say a few more words. The thing that bothers me is how to detonate the astral crystal.”

Dunn looked at the expressionless Ottina, but patiently explained: “I used a big cracking before the detonation, but I couldn’t change a legendary spell into a magical array in a short time. And I can’t get enough material to provide the magic needed for legendary spells. I already want to ask if you have a solution.”

Otiniya understood Dunn’s thoughts. After thinking for a moment, she put down the teacup, raised her finger very cautiously, and wrote a descriptive rune in the air. After the golden runes were formed, they were directly turned into entities. In the hands of Otini, she handed the divine rune to Dunn and said, “(Put this with the astral crystal) and touch the door of chaos (it will detonate) (the astral side) Crystal)).”

“Talk to you if you don’t have enough brain power, you don’t know what you are talking about.”

Dunn carefully accepted the rune of the gods. His body was clearly created by the gods. When he touched the rune of the gods, he still felt very hot and burning his soul and body.

That is the power of God, an area that cannot be touched by mortals.

“Hey.”

Just writing a descriptive rune, Ottina’s face became very pale, and it looked a little tired, and it is conceivable that after she left the realm, her current strength has weakened to what extent.

Ottina took another shortbread and stared at Dunn.

[Is there anything else? 】

Dunn felt that his brain-filling ability was super-god, and he even saw what she wanted to say from Ottina’s eyes.

“Nothing is gone, oh, yes…”

Ottina looked at the shortbread that had bitten a bite and glared at Dunn.

Dunn wiped the cold sweat from his forehead: “That is, after the blast, you can help me fix the space cracks that follow.”

Otiniya did not even talk about it this time, silently eating shortbread and drinking hot tea.

In the end, Dunn was driven out of the room by a silent voice.

After the most critical problem was solved by Ottina, it means that the only problem that Dunn needs to solve is the compression structure of the deep sea torpedo.

Whether the double-layer anti-pressure structure can resist deep sea pressure, just need to test another test product.

Dunn, who was driven out of the study, went straight to the Magic Energy Engineering Institute and found a vacant lab to start slamming.

With the previous experience, he quickly re-created another model this time, and then began the pressure test, and this time the results were very smooth, the deep-sea torpedo suffered a hundred times of pressure before a slight deformation .

The main reason is that Dunn does not have a professional tool for filling high-pressure gas. It is difficult to accurately control the internal pressure by using wind magic, and it is difficult to simulate the deep sea environment on land.

However, after half an experiment, Dunn slammed his head and suddenly returned.

The purpose of his deep-sea torpedo was to blow up the door of chaos. It was originally a one-time consumable. The inside did not carry passengers. It only needed to send the warhead to the door of chaos to achieve its goal.

As for the space inside the deep sea torpedo… there is a hair!

Thicken!

As long as you use a thick enough shell, you can be sure to complete the task!
