Chapter 669 It’s Difficult for a Mouthless Girl to Communicate

Tang En briefly looked through the files compiled by Fiona. In the past few days, Fiona had not been idle when he was away, and she had completed all the things she had assigned to him.

"Well done. Universal alloy has a very wide range of uses and must be produced in large quantities."

After Tang En finished speaking, he still felt a little regretful. If he had studied chemistry, physics, and materials on Earth, he might have been able to find a way to build a set of equipment to find out what elements make ordinary steel qualitatively change. Then A certain element in the two herbs has become a catalyst for magic metal, allowing the properties of magic metal to be fused with ordinary steel to greatly improve its performance. If you can figure it out, you can find a way to get it from gray thistle and silver thread flower. If the corresponding elements are extracted on a medium and large scale and directly synthesized into a universal alloy, the production efficiency will be improved more than just a little bit?

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

Fiona shrugged, glanced at Tang En, and then said expressionlessly: "The other thing is that the midterm exam results have come out. I think it is necessary to give you feedback on this matter. There is a big problem now."

"Huh? Didn't I leave all the exam matters to Pamela?"

"Because students are very resistant to exams... and even because of the appearance of exams, students are full of complaints against you."

Fiona looked at Tang En with a strange look on her face: "Even Illya complained to Miss Elsa several times."

Tang En chuckled when he heard this: "This is the effect we want. Let them enjoy the fun slowly. I haven't even put out one lesson, one practice and three years of college entrance examination and five years of simulation. They should feel lucky."

At this moment, Tang En was full of bad taste. He planned to let these innocent, pure and ignorant children experience the suffering he had experienced, and then he said euphemistically, "When heaven is about to entrust great responsibilities to these people, they must first suffer in their determination."...

Although Fiona didn't understand what Tang En was talking about, she knew it was not a good thing. She spread her hands and said, "After Ms. Pamela finished marking the papers, she conducted a detailed evaluation based on the students' grades and areas of expertise. By adjusting the curriculum and classes, she hopes to teach students in accordance with their aptitude so that each student can master what they are best at."

Tang En frowned: "Isn't it a little early? They have just come into contact with basic education, and they can't see their own talents yet. Basic education must be compulsory and complete."

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

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

Tang En shook his head, took out some small things and threw them on the table: "In the next few days, I want to study something... By the way, go and find Otinia for me. I have something to do with her."

Fiona took a look and found that they were some small parts that she didn't know how to use. She nodded and left.

"Deep-sea torpedoes... Although it's quite simple..."

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

Power is not a problem. The problem is the resistance of deep-sea torpedoes to water pressure. Although the oval structure can effectively reduce water pressure, the deepest point of the abyssal sea can reach four thousand meters. Can the torpedo withstand such strong water pressure? It's 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 strong. Using magic waves to transmit control signals may be interfered. The best option is to use the ubiquitous water element in the deep sea. to achieve communication and control.

The most critical part is how to activate the warhead.

The small parts on the table floated in front of Tang En and were quickly assembled into a mini torpedo. As soon as he waved his hand, a cloud of water appeared in the air, and then enveloped the mini torpedo. Tang En began to pressurize it continuously.

When the pressure increased about fifty times, the mini torpedo had already undergone obvious deformation, which showed that the material was not strong enough to withstand the subsequent pressure.

Tang En frowned: "Sure enough, a single-layer structure is not feasible. This is only fifty times the pressure, which is only equivalent to the strength of about a thousand meters underwater... Then replace it with a double-layer composite structure."

He recalled the material structures he had seen on Earth. He remembered that there was a double-layer pressure-resistant shell structure that added transverse support rods (ribs) between the two partitions, and then filled the interlayer with high-pressure gas to increase the shell's resistance. compressive strength, thereby achieving a stepped pressure drop stress state.

He did it as he thought, and after scattering the water balloons, he immediately started making another mini torpedo.

Not long after, Otiniya pushed open the door and walked in: "Is something wrong?"

Tang En glanced at Otienia, and then he was stunned: "What are you doing?"

Otinia's silver hair is quite beautiful, as soft and smooth as satin under the moonlight, but at this moment, her hair is covered with weeds, and even her clothes are a bit dirty, as if she is in the grass. She was rolling around. As a goddess, this image simply ruined her outlook.

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

"certainly."

Tang En pointed to the sofa: "Sit."

After Otiniya sat down, Tang En brought her a cup of tea and some homemade refreshments, and then said: "I encountered a problem, and I want to use your power to solve it."

Otinia had just picked up a piece of shortbread and was about to bite it. After hearing this, she immediately put it back down alertly: "What?"

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

Tang En was dumbfounded by her vigilance. Unfortunately, Otinia didn't respond at all, but looked straight at him. The girl's deep eyes were full of vigilance.

"Okay, then I'll just tell you."

Tang En sighed and said: "We went to the Sea of ​​Abyss a few days ago and eliminated a group of chaotic creatures near the Broken Islands, as well as an ancient deep-sea monster called Leviathan. This deep-sea monster was corrupted by the native chaotic creatures. , and that native chaotic creature comes from the abyss gate inside the territory of the Raging Wave Murlocs under the deep sea, and now we want to close this abyss gate."

"Are you going to the sea?"

"Of course I can go to the sea, but that won't solve the problem. Now I have thought of a way to use a carrier to send the astral cube crystal to the Gate of Chaos."

"Detonate?"

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

Tang En snapped his fingers and said: "The power of the astral cube crystal explosion is quite impressive. It can directly destroy the space near the Chaos Gate and completely destroy the Chaos Gate. Well, although it will leave some sequelae..."

Otinia took a sip of hot tea and nodded: "It's feasible."

"I know it works because I blew up a Chaos Gate while we were at sea."

Tang En said with a smile: "There is still a hole in the sky. If you can, can you help repair it?"

Using the power of Othinia, the efficiency of repairing space will be greatly improved. It would take a few legendary powerhouses a month to complete the task, but the real gods may be able to solve the problem with just one stroke.

"That's it?"

"It's really hard for you to say more words. What bothers me is how to detonate the astral cube crystal."

Tang En looked helpless at the expressionless Otiniya, and patiently explained: "I used the Great Disintegration Technique when detonating it before, but I couldn't transform a legendary spell into a magic circle to release it in a short time. Form, and I can’t come up with enough materials to provide the magic power required for the legendary spell. I’d like to ask you if there is a way to solve it.”

Only then did Otinia understand what Tang En was thinking. After thinking for a moment, she put down the tea cup, raised her finger very carefully, and wrote a divine rune in the air. After the golden rune was formed, it directly turned into The entity was caught in Otinia's hand. She handed the divine word rune to Tang En and said: "Put this together with the astral cube crystal. When it comes into contact with the Chaos Gate, it will detonate (the star)." Boundary crystal)."

"If I'm talking to you and my brain power isn't strong enough, I won't know what you're talking about."

Tang En carefully accepted the divine word rune. His body was obviously created by the gods, but when he came into contact with this divine word rune, he still felt a very hot power burning his soul and body.

That is the power of God, a realm that cannot be touched by mortals.

"Long-winded."

After just writing a divine rune, Othiniya's face became very pale and she looked a little tired. One can imagine how weak her power has been after leaving the divine world.

Otiniya picked up another piece of shortbread and stared at Tang En.

【Is there anything else? 】

Tang En felt that his ability to think things through was amazing. He actually saw what Otinia wanted to express in her eyes.

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

Otinia looked at the shortbread that she had already taken a bite of, and glared at Tang En.

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

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

In the end, it was Tang En who was driven out of the room with a silent and embarrassing aura.

After the most critical problem was solved by Otinia, it meant that the only thing Tang En needed to solve next was the problem of the pressure-resistant structure of the deep-sea torpedo.

Whether the double-layer compression-resistant structure can withstand deep-sea pressure only needs to be tested by making another experimental product.

After being kicked out of the study, Tang En ran directly to the Magic Energy Engineering Research Institute, found a vacant research room, and started tinkering.

With the previous experience, he quickly made another model this time, and then started the pressure test. The result this time was very smooth. The deep-sea torpedo suffered a hundred times the pressure before it showed slight deformation. .

The main reason is that Tang En does not have professional tools for filling high-pressure gas. It is difficult to accurately control the internal pressure using wind magic. After all, it is difficult to simulate the deep sea environment in experiments on land.

But after experimenting for a long time, Tang En suddenly came back to his senses as he slapped his forehead.

His purpose of building a deep-sea torpedo was to blow up the Gate of Chaos. It was originally a one-time consumable, and it did not carry passengers inside. It only needed to be able to send the warhead to the Gate of Chaos to achieve its purpose.

As for the space inside the deep-sea torpedo...it has a use!

Thicken!

As long as you use a thick enough shell, you're guaranteed to get the job done!
