Don briefly flipped through the documents that Fiona had organized, and in the last few days when he was away, Fiona had not been idle, and had done everything he had explained. Pen "Fun" Pavilion www.biquge.info

"Well done, universal alloys are very versatile and have to be produced in large quantities."

After Tang En finished speaking, he still felt a little regretful in his heart, if he studied chemistry on the earth, he might be able to find a way to get a set of equipment to figure out what the elements that make ordinary steel qualitatively transformed, and one of the two herbs has become a catalyst for magic metal, so that the characteristics of magic metal can be fused with ordinary steel, and the performance can be greatly improved, if you can figure it out, you can find a way to extract the corresponding elements from gray thistle and silver thread flower on a large scale and directly synthesize a universal alloy, How much more than a little bit of productivity improvement?

It's a pity that the concubine really can't do it......

Fiona shrugged, glanced at Donn, and then said expressionlessly: "Another is that the results of the midterm exam have come out, I think it is necessary to give you feedback on this matter, there is a big problem now." ”

"Huh? Isn't it all up to Pamela to take the exam? ”

"Because students are very resistant to exams...... Even because of the appearance of exams, students are full of complaints about you. ”

Fiona looked at Don with a strange expression, "Even Illia has complained to Miss Elsa several times. ”

Tang En smiled when he heard this: "That's what you want, let them enjoy the fun slowly, I haven't taken out a lesson and a practice and a three-year college entrance examination and five-year simulation, they should feel lucky." ”

At this moment, Don is full of evil taste, he intends to let these innocent, pure and ignorant children feel the suffering he has experienced, and then he will say in the beautiful name "Heaven will descend on the people, and the people must first suffer their hearts"......

Fiona didn't understand what Don was talking about, but she knew it wasn't a good thing, she spread her hands and said, "After Ms. Pamela finished grading the papers, she made a slight adjustment to the curriculum and class according to the students' grades and directions, and she hoped to be able to teach each student according to their aptitude, so that each student can master what they are best at." ”

Tang En frowned: "Isn't it a little early?" They are only now in contact with basic education, and they do not yet see their talents, and basic education must be accepted compulsorily and completely. ”

"You can go and talk to Lady Pamela about this."

"You tell her for me, I don't have time."

Don shook his head, took out some small things and threw them on the table: "In the next few days, I will study one thing...... By the way, you go and help me get Otinia, I'll find her for something. ”

Fiona looked at it, saw that it was some small part that she didn't understand, nodded and left.

"Deep-sea torpedoes...... It's pretty simple......"

Don rubbed his head, I'm afraid only he knows how big the problem is.

The power aspect is not a problem, the problem is the resistance of the deep-sea torpedo to water pressure, although the oval structure can effectively reduce the water pressure, but the deepest part of the abyssal sea can reach four thousand meters, and whether the torpedo can withstand such a strong water pressure is a big problem.

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

The most critical point is how to excite the warhead.

The small parts on the table floated in front of Donn, quickly combined into a mini torpedo, and as soon as he waved, a splash appeared in the air, and then wrapped the mini torpedo, and Donn began to pressurize continuously.

When the pressure is increased by about fifty times, the mini-torpedo has already undergone obvious deformation, which indicates that the strength of the material is not strong enough to resist the next pressure.

Tang En frowned: "Sure enough, the single-layer structure will not work, this is only fifty times the pressure, which is only equivalent to the strength of about a thousand meters under the water...... Then replace it with a double-layer composite structure. ”

He recalled the material structure he had seen on the earth, and remembered that there was a double-layer pressure-resistant shell structure, in which a transverse support rod (rib bar) was added in the middle of the two layers of partitions, and then the interlayer was filled with high-pressure gas to improve the compressive strength of the shell, so as to achieve a stepped pressure drop stress state.

He did it as soon as he thought of it, and as soon as he dispersed the water balloon, he began to make another mini-torpedo.

It didn't take long for Otinia to push the door in: "Something? ”

Don glanced at Otinia, and then he was stunned, "What are you doing here?" ”

Otinia's silver hair is quite beautiful, as smooth as satin in the moonlight, but at the moment her hair is full of weeds, and even the clothes on her body are a little dirty, as if she is rolling in the grass.

Instead of answering Donn's question, Otinia repeated, "Something?" ”

"Of course."

Don pointed to the couch, "Sit." ”

After Otinia sat down, Don brought her a cup of tea, took some homemade refreshments, and said, "I have a problem, and I want to use your strength to solve it." ”

As soon as Otinia picked up a piece of shortbread and was about to bite into it, she immediately put it back vigilantly when she heard this: "What? ”

"Well, you eat, I'm not using you to do anything bad."

Don was made to laugh and cry by her vigilance, but unfortunately Otinia didn't respond at all, just looked straight at him, and the girl's deep eyes were full of vigilance.

"Okay, then I'll get straight to the point."

Tang En sighed and said, "A few days ago, we went to the Abyssal Sea, and solved a group of chaotic creatures near the Shattered Islands, and there is an ancient deep sea demonic beast called Leviathan, this deep-sea demonic beast was corrupted by the original chaos creature, and that primordial chaotic creature came from the abyssal gate inside the Angry Waves Fishman territory under the deep sea, and now we want to close this abyssal gate." ”

"You go to the sea?"

"Of course I can go to the sea, but that won't solve any problems, and now I've thought of a way to use a carrier to send the astral crystal to the Chaos Gate."

"Detonate?"

"That's right, it's to detonate the astral crystal!"

Tang En snapped his fingers and said, "The power of the astral crystal explosion is considerable, it can directly destroy the space near the Chaos Gate and completely destroy the Chaos Gate, although it will leave a little sequelae......"

Otinia took a sip of the hot tea and nodded, "Feasible." ”

"I know it works, because I blew up a Chaos Gate while I was at sea."

Tang En smiled and said, "There is still a crack in the sky, if you can, help fix it?" ”

Using the power of Otinia, the efficiency of repairing the space will be greatly improved, and what it would take a few legendary powerhouses to do well in a month may be solved by a true god with just a few strokes.

"That's it?"

"It's so hard for you to say a few more words, the thing that bothers me is how to detonate the astral crystal."

Tang En looked at the expressionless Otinia helplessly, and patiently explained: "I used the Great Cracking Technique when I detonated it before, but I couldn't transform a legendary spell into the form of a magic array release in a short period of time, and I couldn't get enough materials to provide the magic power required for the legendary spell, I want to ask you if there is a way to solve it." ”

Otinia understood Donn's thoughts, and after thinking for a while, she put down the teacup, raised her finger very carefully, and wrote a divine rune in the air, after the golden rune was formed, it directly turned into an entity and was grabbed by Otinia's hand, she handed the divine word rune to Don and said: "(Put this together with the Astral Crystal), when it comes into contact with the Chaos Gate, it will detonate (the Astral Crystal)." ”

"If you talk to you, if your brain is not strong enough, you must not know what you are talking about."

Tang En carefully accepted the Divine Word Rune, his body was obviously created by the gods, and when he came into contact with this Divine Word Rune, he would still feel a very hot power scorching his soul and body.

It was the power of the gods, a realm that could not be touched by mortals.

"Long-winded."

Just writing a word rune, Otiniah's face became very pale, and she looked a little tired, you can imagine how weakened her strength has now after leaving the divine realm.

Otinia picked up another piece of shortbread and stared at Donn.

[Anything else?] 】

Don felt that his brain replenishment ability was already superb, and he could see what Otinia was trying to express in her eyes.

"No, no, no, oh, yes......"

Otinia looked at the shortbread she had already taken a bite of and glared at Don.

Tang En wiped the cold sweat from his forehead: "That's it, after the explosion, please help me repair the spatial cracks that appear later......"

Otinia didn't even say anything this time, silently eating shortbread and drinking hot tea.

In the end, it was Don who was kicked out of the room by a wordless awkward aura.

After the most critical problem was solved by Otiniah, it meant that the only thing that Donn needed to solve next was the compressive structure of the deep-sea torpedo.

Whether the double-layer compressive structure can resist the pressure of the deep sea only needs to be tested by making another experiment.

Kicked out of the study, Don went directly to the Magic Energy Engineering Research Institute, found a vacant research room and began to tinkle.

With his previous experience, he quickly rebuilt another model this time, and then began pressurization tests, and this time the results were very smooth, and the deep-sea torpedo was subjected to a hundred times the pressure before it appeared slightly deformed.

The main reason is that Donn does not have a professional tool to fill high-pressure gas, and it is difficult to accurately control the internal pressure if he uses wind magic, and it is difficult to simulate the deep-sea environment in experiments on land.

But after experimenting for a long time, Don En slapped his head and suddenly came back to his senses.

The purpose of his deep-sea torpedo is to blow up the Chaos Gate, which is originally a one-time consumable, and it does not carry passengers inside, so it only needs to be able to send the warhead to the Chaos Gate to achieve the goal.

As for the space inside the deep-sea torpedo...... There's a hair!

Thickened!

As long as you use a thick enough shell, you are guaranteed to complete the task! (To be continued.) )
