After the familiar space was distorted, Yanis's figure was revealed, with a hint of doubt on her face.

"Lord, how do you know I'm here? ”

"It's simple, because the familiar feeling you had been with me all the time has suddenly returned, and I know you're back. Xu Yi replied with a smile.

"Familiar?" Annis wondered. "What's that like?"

"I can't tell. Anyway, if you're next to me, even if I can't see you, there's always a strange feeling that lets me know that someone is around. Xu also explained.

"And if other elves were around you with shadow magic, wouldn't you be able to find out?" asked Janiss.

"It's not quite the same. Xu Yi shook his head. "Maybe it's because you've been with me for a long time, even if you hide with me with the Shadow Concealment Technique, I can feel that it's you, but if it's another elf, then I may not be able to find out. If anything, maybe it's because of the smell of you that betrays you?"

"Smell?" Annis frowned slightly, and looked down at her body to sniff. "It doesn't smell special. ”

Xu Yi also had the urge to lean over and sniff it, but thinking that it would be too abrupt to do so, he suppressed this impulse, smiled, and changed the topic: "Okay, stop gossiping." How did you get on your solo business trip?"

"Oh, I met with Patriarch Sluby, Patriarch Monto, and the Elders, and relayed to them what you had to say. Then they asked me to bring something back and give it to you. ”

Annis untied a large backpack from her back and opened it to reveal a pile of iron lumps of various colors.

Xu Yi was taken aback: "You can't have carried so many things all the way from the Falling Rain Forest, right?"

"yes. What's wrong?" Annis asked curiously.

Xu Yi was speechless.

Such a large backpack is also full of all kinds of iron lumps. The weight is more than 100 catties.

Yanis carried such a heavy backpack and ran more than 200 kilometers from the Falling Rain Forest, it should be said that the elves are very talented. Or should I say she's stupid?

"Don't abuse yourself like this next time. I just asked you to bring back one or two samples that Patriarch Sluby said, but I didn't say that you should carry so much. Aren't you too serious?" Xu Yi shook his head and said.

"It's all samples. Yanis pulled out a stack of papers from the compartment of her backpack and handed it to Xu Yi. "This is the list given by Patriarch Sluby, saying that it is marked with the recipe of each sample and the results of their initial tests, and I want to show it to you. ”

"It's all samples?" Xu Yi glanced at his backpack, thinking to himself that there are only more than twenty kinds of at least there, could it be that the Norma tribe has actually researched so many new alloy steels in one go in the past few months?

If that were the case, the dwarves would have had a terrible talent for material craftsmanship.

However, after reading the list, Xu Yi was a little crying and laughing.

It turned out that these so-called samples were actually just the inspiration that the Sluby patriarch received from Silver Leaf Steel. During this time, various strange ingredients were constantly added to the molten iron, including cow dung powder.

It is strange that the so-called alloy steel produced in this way can have any special effect.

However, after checking the results, Xu Yi found that the twenty-three alloy steel samples that Patriarch Sluby asked Yani to bring over were really effective.

Aside from some characteristics such as "shattering when knocked", which made Xu Yi almost vomit blood, one of the alloy steels listed as "No. 17" by the Sluby patriarch actually showed excellent performance in a series of real products, reflecting extremely strong corrosion resistance and high temperature resistance.

Xu Yi is still very satisfied with being able to emerge such an alloy steel with special characteristics in so many useless research results.

This kind of steel with high-strength, corrosion-resistant, and high-temperature resistance can be used in a wide range of applications, and if the characteristics of stainless steel can be added, countless new types of magic machines can be developed with this steel.

"Good. I'll see, which No. 17 alloy steel is......" Xu Yi rummaged through his backpack and found an iron lump with the word No. 17 engraved on it.

This dark red iron bump is extremely heavy in the hand, and the density is significantly greater than that of ordinary pig iron. It seems that the dwarves have added special ingredients to it. The internal structure of the entire steel has been altered.

Xu Yi couldn't help but feel a trace of emotion in his heart.

Although the Sainz continent has found more than the earth in terms of technology, it can always find some advantages that are not available on the earth.

Taking silver leaf steel as an example, it is not easy to make alloy steel with excellent characteristics like silver leaf steel on earth. However, on the continent of Sainz, it is only necessary to add the ubiquitous Silver Leaf Grass powder to the molten iron.

As for the current No. 17 alloy steel, which has corrosion resistance and high temperature resistance. According to the list given by Patriarch Sluby, it is nothing more than the addition of several equally common plant stem and leaf powders to the molten iron. It has not been refined by any special process at all.

"What the hell is this principle?" As a rigorous engineering student, Xu Yi was really puzzled by this strange phenomenon.

But this is the reality, and Xu Yi finally had to explain that the Sainz continent and the earth are different after all.

Seeing that Xu Yi had finished reading all the samples, Yanis reached into her arms, took out a small box, and handed it over.

"This is what the elder asked me to bring to you, saying it was a gift for you. Yanis said.

"What is the gift?" Xu Yi opened the box curiously and found that there was a delicate model of a villain lying in this small wooden box.

The figure is shiny all over, with the exception of the bright golden yellow hair, which is a pale milky white color.

Xu Yi touched it and found that this villain model should be made of plastic.

However, what surprised him the most was that this carved villain was Steele!

Look at this though only less than twenty centimeters tall. But it is incomparably finely carved, and Steele's face is perfectly presented. Even the model where every hair is slender and visible, Xu couldn't help but exclaim. "It's so beautiful! If Steele sees it, he'll love it very much." Yanis, thank you Elder Elucia for me, I am very pleased with her gift. ”

Yanis smiled sweetly: "The elder said that this is a gift for a friend, no need to thank you." In addition, the elder said that after seeing this gift, you should understand what she meant. ”

Xu Yi glanced at the villain in his hand, and then rubbed it with his fingers. Nodding: "That's right, I see." ”

Elder Elucia asked Annis to bring this gift, undoubtedly to tell him that the Nightsong Clan's research on plastics had met Xu Yi's requirements.

looked into the wooden box again, and sure enough, in addition to this villain in the wooden box, there was a transparent milky white and square plastic lying at the bottom.

Xu Yi picked up the piece of plastic, first leaned close to his nose and sniffed it vigorously, but not only did he not smell the expected stench. Instead, he smelled a faint fragrance and nodded with satisfaction.

Then he put the plastic on the ground, picked up a thin sharp stone on the ground, and watched under the surprised gaze of Janis. Aim the sharp corners of the stone at the plastic on the ground and smash it hard.

"Poof—"

The stone slammed into the plastic with a muffled thud.

Xu Yi took the stone away and took a serious look. It was found that there was only a very small pit on the surface of the plastic, and the rest of the plastic was not affected in any way.

"Good. Whether it's smell, hardness and flexibility, it's okay, and then it's the most important test. ”

Xu also picked up the plastic again. Pinched in the palm of his right hand, the magic power in his body surged, and after a while, a thick cold air seeped out of his right hand, and in an instant, the surrounding air that seemed a little warm because of the entry into May turned into an extremely cold.

Level 6 Water Magic-Frozen Nova.

This is the first level 6 magic that Xu Yi has mastered not long ago.

Once the magic of Frozen Nova is cast, it can rapidly cool the surrounding air, and the temperature will be lowered differently depending on the magician's magic and mastery of the magic.

It is said that if a magister casts this magic, it can even freeze a stone directly at the lowest time.

And although Xu Yi cast this magic is not so exaggerated, it can also quickly reduce the surrounding temperature to below zero.

A moment later, a small area of snow powder fell around Xu Yi's right hand, and the entire right hand became white and even a little transparent because of the effect of this magic.

Yanis looked at Xu Yi's right hand, her big eyes full of surprise.

Although she is currently majoring in some special elven magic and has not yet begun to learn elemental magic, she certainly recognizes the magic that Xu Yi is using as a frozen nova.

After following Xu Yi for so long, she knew very well that Xu Yi was actually a magician with the strength of a fifth-level magician, and he was able to use sixth-level magic, which had already surprised her very much, and what surprised her even more was that Xu Yi was able to maintain this magic for so long!

Although the range of this magic was limited to Xu Yi's right hand, and the mana consumed was greatly reduced, he was able to maintain it all the time, and maintained it for so long, not only to prove that his mastery of this magic was far more exquisite than that of ordinary magicians, but also to prove that his magic power was no weaker than that of a sixth-level magician.

Yanis couldn't help but think of Steele's relays of Camilla's evaluation of Xu Yi.

"If this kid had focused on magic, he would have a good chance of becoming a powerful magister. ”

Thinking of this, Yanis couldn't help but feel a little more regret in her eyes when she looked at Xu Yi.

After following Xu Yi for so long, of course she knew very well that Xu Yi really loved the research of magic machinery.

Even if he would spend his time studying magic, in Yanis's opinion, it was probably to make it easier for him to study magic machines.

If he had devoted all his time and energy to the study of magical machines, then Annis was sure that with his talent, he would definitely become a powerful magister.

Xu Yi on the side didn't care what Yanis was thinking, and still observed the plastic block in his hand intently.

Seeing that the plastic block had not shown any signs of deformation over time, Xu Yi smiled with satisfaction.

After insisting on casting the frozen nova for a few more minutes, Xu Yi reined in his magic and lifted the magic.

Due to the rapid temperature change on the surface of the plastic block, the newly formed layer of frost turned into water droplets, and then merged into streams and slid down the smooth surface.

Xu Yi carefully observed the surface of the plastic block and found that the small pit he had pierced with a stone just now was still the same, without the slightest change.

"Great!" Xu Yi looked at the plastic block in his hand, showed a happy smile, and turned to Yanis and said, "Yanis, haven't you kept asking me what value you elf clan contains?

Yanis looked at the ordinary piece of resin in Xu Yi's hand and wondered in her heart.

It's an ordinary resin that can be found everywhere, so why do adults think it's a treasure......?
