"Tuk-tuk-tuk-"

There was a knock on the door, and Akali's round face peeked out from behind the open door.

Seeing that it was Xu Yi standing outside the door, the expression on Akali's face became a little unnatural, and after a pause, he smiled and said, "Lord, you're back." ”

"Hmm. Xu Yi nodded and glanced into the room. "How's it going? Is Vivien okay?"

"The first one to ask when I came back was Vivien......" Akali muttered, turning away. "Come in, Vivien is upstairs, she hasn't slept yet, I'll call her down." ”

Seeing Akali turn around and run up the stairs, Xu Yi looked back behind him, but did not find Yanis's figure.

Looks like the female elf should now use the shadow magic to hide her figure again.

Thinking that she had followed him all the way just now, Xu Yi couldn't help but knock his head with a headache.

Elves are stubborn, and this Janis is especially stubborn.

No matter what Xu Yi says, she just refuses to leave Xu Yi's side, as if Xu Yi will disappear as soon as she leaves.

Xu Yi's persuasion was fruitless, the threat was useless, and he couldn't get rid of it if he wanted to, and finally he could only reluctantly accept this reality.

Fortunately, Yanis doesn't like to show her face in front of other people, and she can use the shadow concealment technique to hide her figure at any time, but it won't affect Xu Yi too much.

Shaking his head and walking in the door, Xu Yi found that this living room was actually neatly tied, and it was not as cluttered as every time he came here before.

Seeing that Akali had already run down the stairs again, Xu Yi couldn't help but ask her in surprise, "Hey, Akali." Have you changed sex? You're actually starting to learn how to tidy up the house. ”

Akali glanced at Xu Yi with some resentment, and snorted softly: "It's not because you always say that I don't clean up the house, adult. ”

"If my words work like that. That's great. Xu Yi laughed, and suddenly realized that something seemed to be wrong. After thinking about it, I looked up and found that a yellowish transparent cylinder was hanging from the roof of the living room with a ribbon.

Something in the transparent cylinder seemed to be emitting a strong light, but when it was filtered by the cylinder, it was dyed with a mild yellowish glow.

The reason why Xu Yi felt that something was wrong was because he suddenly remembered that it was obviously night outside, but inside this room was very bright, as if it was day.

If you rely on candle lighting, you will never be able to achieve this effect.

Glancing at the pale yellow cylinder. Xu Yi couldn't help but shout in surprise: "Hey! you guys have actually successfully researched!"

Akali narrowed her eyes and smiled, "Yes, Lord Grow, this is our newly developed magic lamp, how about you take a look?"

Xu Yi raised his hand, but found that the magic lamp was hanging so high that he couldn't reach it at all.

Just as he was thinking about whether to find a stepping stone to take off the magic lamp and take a closer look, a chuckle sounded from the direction of the stairs, and Evita's voice rang out.

"President, if you want to see the magic lamp. Why don't you look at this in my hand? ”

Xu Yi looked back and suddenly felt that his eyes lit up.

Up the stairs, Evita descended the stairs.

Perhaps because of the late period, she was wearing this loose dressing gown. Although her figure is covered tightly, it adds a sense of laziness, but it is another style and charm.

It attracted Xu Yi's attention even more. It was the glowing thing that Evita was holding in both hands.

It has a circular wooden base and a clear glass shroud of lilac at the top.

At this time, the glass cover was evenly emitting a not very strong light. Because it is covered by a glass cover, it can only reveal a hazy lilac light. Enveloping Evita holding it all over her body actually added a mysterious aura to Evita.

After Xu Yi glanced at it, he was even more surprised in his heart: "Evita, you have even solved the problem of the strength of the magic array?"

Evita smiled slightly, and did not answer Xu Yi's question, but turned sideways and let Vivien, who was hiding behind her.

Seeing Vivian's somewhat shy and dodgy expression under the light purple light, Xu Yi couldn't help but be stunned.

"Vivien, what are you doing hiding behind Evita? Why? Don't you recognize me if you haven't seen me for more than ten days?"

Vivian hurriedly shook her head, glanced at Evita, and saw that Evita nodded to her with an encouraging look, so she hesitated for a moment, moved down the stairs, and slowly came to Xu Yi's side.

When she didn't go to Xu Yi's side, her expression seemed to be very nervous, and when she got to Xu Yi's side, she suddenly breathed a sigh of relief, and her expression suddenly relaxed.

Xu Yi looked at her a little inexplicably, and couldn't help but reach out and touch her forehead.

"I don't have a fever...... I said Vivian, what's wrong with you?"

Vivien's cheeks, which had already shown a few wisps of blush from the shower, turned a little redder and shook her head vigorously.

"It's really hard to guess what the little girl is thinking. Xu Yi could only mumble in his heart, turned his head and beckoned to Evita and Akali: "Come, Evita, you bring the magic lamp in your hand and let me take a look." Akali, you take out the research results of your research these days, and I will see how far you have come. ”

When Evita came over with the crystal lamp, Xu Yi unceremoniously asked Evita to disassemble the magic lamp, and unsurprisingly found a very familiar magic array on the base of the magic lamp.

But if you take a closer look, you will find that this magic array has changed a lot compared with the magic array on the base of the magic crystal that Xu Yi bought with money before or the magic array that Evita drew later from memory.

Xu Yi looked at it for a while, and also found a difference in this magic array, that is, above this magic array, it was also covered with dense and thin weeds. Xu Yi carefully observed it, and only then did he realize that although these weeds had changed color. But it's really fluorescent grass, yes.

Xu Yi thought about it, reached out and pressed lightly on these fluorescent grasses. Then he found that under his light press, the thin fluorescent grass had broken in several places.

Seeing Xu Yi's movements, Evita wanted to stop it but it was too late, and when she saw Xu Yi cut off a few fluorescent grasses, she suddenly showed a wry smile.

"President, have you found a problem?"

Xu Yi glanced up at her and nodded lightly: "This is a very common question, it is not difficult to find." Didn't you come up with a solution?"

Evita shook her head helplessly: "Although fluorescent grass can shine perfectly, it is just dead grass after all. It is very fragile, and no matter what we think, it is difficult to guarantee that it will not be destroyed by external forces. So you see, whether it's the magic lamp hanging on the ceiling or the magic lamp in my hand, the outside is wrapped in a glass cover, just to keep the fluorescent grass from being damaged by external forces. ”

Xu Yi nodded: "This idea is good, the problem is that the limitations are too great." And we can't just take all the air out of the glass enclosure or simply inject some inert gas into it to prevent the material from oxidizing. This design will certainly not last long. ”

Evita looked at Xu Yi a little blankly, she didn't understand what Xu Yi meant by pumping out air, injecting inert gases and preventing oxidation of materials, but she knew that Xu Yi would never talk nonsense, so she didn't put forward any opinions. Instead, he silently wrote down everything Xu Yi said.

At this time, Akali had already taken all their research materials during this time, and Xu Yi immediately flipped through them carefully after taking them.

These materials are very thick, and Xu Yi looks at them very seriously. So it took more than a while to finish reading.

After reading it all, Xu Yi closed his eyes and thought for a moment. Only then did he say to the two: "I found that you two have overlooked a very important issue. ”

Evita and Akali were stunned at the same time: "What's the problem?"

Xu Yi got up and came to the table, and touched the magic lamp that Evita had opened a few times just now. Fished out all the fluorescent grass from the magic lamp, then asked Akali to bring a small bowl, and then poured the fluorescent grass that had been shattered into countless roots, and crushed them into powder with a soup spoon.

Seeing Xu Yi's movements, Akali asked in surprise, "Elder, don't you think that fluorescent grass powder can also absorb the lightning in the magic array to emit light?"

"Why not?" Xu Yi asked rhetorically, pointing to the materials that had been set aside. "Did you find that there is a description in the information about fluorescent grass, mentioning that even if the fluorescent grass withers, it will still absorb lightning and emit bright light?"

"That's right, so we can use fluorescent grass to make this real, if it has to be a living fluorescent grass, then we can't even develop these two magic lights. But what does this have to do with your thoughts, Lord Grown?Withered fluorescent grass is also fluorescent grass, but grinding it into powder is another thing entirely, right?" asked Akali, still puzzled.

Evita also looked puzzled, thinking that Xu Ye was a little whimsical.

Xu Yi smiled slightly: "Since the withered fluorescent grass also has the property of storing lightning and delaying the release of light, then this obviously has nothing to do with the vitality of the fluorescent grass, but the material of the fluorescent grass itself determines this characteristic." Since this is the case, there should not be much difference between the fluorescent grass that is molded and the fluorescent grass that has been turned into powder. Since it is theoretically possible, why don't we try to make a real yàn? The so-called real yàn is to find a way to succeed from 10,000 failures. ”

Hearing this, Evita and Akali couldn't help but nod their heads at the same time, thoughtful.

At this time, Xu Yi had already crushed all the fluorescent grass, and then he asked Evita to set up a thunderbolt circle on the table, and then carefully scattered the fluorescent grass powder according to the trajectory that Evita and Akali had studied.

When he was ready, Xu Yi glanced at Evita and Akali, who were a little nervous, smiled, stretched out a finger, and a trace of magic came out.

With a flash of lightning, the lightning array was instantly activated.

A moment later, a faint light emanated from the fluorescent grass powder that covered the magic array, and in the blink of an eye, it gradually brightened, illuminating all the dark places on the table, and also illuminating the smiling faces of the three people around the table full of surprise.
