Things from Another World

Tang En took a brief look at the files that Fiona had sorted out. When he was away these days, Fiona wasn't idle, and everything he told him was done well.

"Well done, universal alloys are very versatile and must be mass produced."

After Tang En said, I still feel a bit regretful. If he studied chemistry, physics, and materials on Earth, he might be able to find a way to understand the elements that make the ordinary steel qualitatively change. One of the two herbs has become a catalyst for magic metal, which allows the characteristics of magic metal to be integrated with ordinary steel. The performance is greatly improved. If you can figure it out, you can find a way to use thistle and silver thread. Medium and large-scale extraction of the corresponding elements directly synthesize universal alloys. How much can the production efficiency be improved?

It's a pity Chen Chen can't do it ...

Fiona shrugged, squinting at Down, and then said blankly: "The other is that the results of the midterm exam have come out. I think it is necessary to give you feedback on this matter. The problem is very big now."

"Well? Didn't everything for the exam be given to Pamela."

"Because the students are very resistant to the test ... even the appearance of the test has caused students to complain about you."

Fiona looked at Tang En with a strange look: "Elia even complained to Miss Elsa several times."

Tang En heard a smile and said, "What I want is this effect, let them enjoy the fun slowly. I haven't taken out one lesson, one practice and three years of college entrance examination, and five years of simulation. They should be grateful."

Tang En at this moment is full of wickedness. He intends to experience the suffering he has experienced for these innocent and ignorant children, and then calls it "the heaven will descend to the people of Sri Lanka."

Although Fiona didn't understand what Tang En was talking about, it was clear that it was not a good thing. She spread out her hand and said, "After finishing the papers, Ms. Pamela did a subtle review based on the students' grades and their good direction. She wants to teach students according to their aptitude, so that each student can master what they are best at. "

Tang En frowned: "Is it a bit early? They have just come into contact with basic education, and they don't see their respective talents. Basic education must be accepted compulsively and completely."

"You can discuss this matter with Ms. Pamela."

"Tell me to tell her, I don't have time."

Tang En shook his head, took out some small things and threw them on the table: "The next few days, I'm going to study something ... By the way, go and help me find Otinija, I'll ask her something."

Fiona glanced at it and found that it was some small unclear part, and nodded and left.

"Deep-sea torpedo ... although it is quite simple ..."

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

The power is not a problem. The problem lies in the resistance of deep sea torpedoes to water pressure. Although the oval structure can effectively reduce water pressure, the deepest part of the abyss sea can reach 4 kilometers. Can the torpedo withstand such a strong water pressure? It's a big problem.

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

The key point is how to fire the warhead.

Those small parts on the table floated in front of Tang En, quickly assembled into a mini torpedo. When he beckoned, a spray of water appeared in the air, and then wrapped the mini torpedo, and Tang began to pressurize continuously.

When the pressure increased by about 50 times, the apparent deformation of the mini torpedo has already occurred, which indicates that the material is not strong enough to resist the next pressure.

Tang En frowned: "Surely a single-layer structure does not work. This is only fifty times the pressure, which is only equivalent to about a thousand meters of water ... then replace it with a double-layer composite structure."

He recalled the material structure that had been seen on the earth, and remembered that there is a double-layer pressure-resistant shell structure that adds horizontal support rods (ribs) between the two layers of the next wall, and then fills the sandwich with high-pressure gas to improve the shell's resistance Compressive strength to achieve a stepped pressure drop stress state.

He did it as soon as he thought about it. After the water polo was scattered, he immediately started making another mini torpedo.

It didn't take long for Eutinia to push in the door: "Is something wrong?"

Tang En glanced at Otinia, then stunned: "What are you doing here?"

Eutinia's silver hair was quite beautiful, as soft and smooth as satin in the moonlight, but at this moment her hair was covered with weeds, and her clothes were a little messy, like in the grass It was a goddess, but this image was simply ruined.

Otinija did not answer Tang En's question, but repeated: "Is there something wrong?"

"of course."

Tang En pointed to the sofa: "Sit."

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

Otinija had just picked up a piece of shortbread and was going to bite it. When she heard it, she immediately put it back alertly: "What?"

"Uh, you eat, I'm not using you to do bad things."

Tang En was made to cry and laugh at her vigilance, but Otinija didn't respond at all, but just stared at him, the girl's deep eyes were full of vigilance.

"Okay, then I'll talk straight."

Tang En sighed and said, "The other day we went to the Abyss Sea and settled a group of chaotic creatures near the Broken Isles. There was also an ancient deep-sea Warcraft called Leviathan. This deep-sea Warcraft was eroded by the original chaotic creatures. , And the native chaotic creature came from the abyss door inside the terrifying murloc territory under the deep sea, and now we want to close this abyss door. "

"You go to sea?"

"Of course I can go to the sea, but that doesn't solve any problems. Now I think of a way to use a carrier to send the astral crystal to the gate of chaos."

"Detonate?"

"That's right, it's detonating the astral cube!"

Tang En snapped his fingers and said, "The power of the astral crystal explosion is quite considerable. It can directly destroy the space near the gate of chaos and completely destroy the gate of chaos. Well, although it will leave a little sequel ..."

Otinija sipped her hot tea lightly and nodded: "It works."

"I know it works, because I blew up a door of chaos while at sea."

Tang En said with a smile: "The sky is still cracking, if you can, help fix it?"

Utilizing the power of Otinija, the efficiency of repairing space will be greatly improved. Several legendary strongmen need a month to do things well, and the real shrine may only need a swipe to solve the problem.

"Is this what?"

"It's really hard for you to say a few more words. The thing that bothers me is how to detonate the astral cube."

Tang En looked at the expressionless Eutinia helplessly, and explained patiently: "I used the big smashing technique before the detonation, but I could not transform a legendary spell into a magic array in a short time. Form, and I ca n’t get enough material to provide the magic required for the legendary spells, I ’ve wanted to ask you if there is a solution. ”

Only then did Otania understand Tang En's thoughts. After thinking for a moment, she lowered the tea cup, raised her finger very carefully, and wrote a godly rune in the air. After the golden rune was formed, it was directly transformed into The entity was captured by Otinia, and she passed the rune of God's Word to Tang En. Boundary crystal). "

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

Tang En carefully accepted the rune of God's Word. His body was obviously created by the gods. When he touched this Rune of God, he still felt a very hot force burning his soul and body.

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

"Well."

Just writing a rune of God's words, Eutinia's face became very pale, and she looked a little tired, but imagined that she had weakened to the present strength after leaving the realm of God.

Otinija picked up another shortbread and stared at Don.

[Is there anything else? 】

Tang En felt that his brain-tonicity was supernatural, and he could see what she wanted to express from Eutinia's eyes.

"No more, no, oh, right ..."

Otinija looked at the shortbread that had taken a bite and glared at Tang En.

Tang En wiped the cold sweat on his forehead: "That is, after exploding, please help me to repair the subsequent space cracks ..."

Otinija didn't even say a word this time, eating cookies and drinking hot tea in silence.

In the end, Tang En was kicked out of the room by the embarrassment of silence.

After the most critical problem was solved by Otinija, it means that the next thing that Tang En needs to solve is the compression structure of deep sea torpedoes.

Whether the double-layer compressive structure can withstand the pressure of the deep sea, just need to make another experiment to test it.

Driven out of the study, Tang En went directly to the Magic Energy Engineering Research Institute, found a vacant research room, and started tinkering.

With previous experience, he quickly made another model this time, and then started the pressure test. This time, the results were very smooth. The deep-sea torpedo underwent a hundred times pressure before it slightly deformed. .

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

But after half a day of experimenting, Tang En patted his brain and suddenly returned to his mind.

The purpose of building a deep-sea torpedo was to blow up the Gate of Chaos. It was originally a one-time consumable and did not carry passengers inside. He only needed to send the warhead to the Gate of Chaos to achieve the goal.

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

Thicken!

As long as you use a thick enough shell, you can guarantee the completion of the task!
