"Tuk-tuk-tuk-"
There was a knock on the door, and Akali's round face poked out from behind the open door.
Seeing Xu Yihou standing outside the door, the expression on Akali's face became a little unnatural. She paused and then said with a smile: "Mr. President, you are back."
"Yes." Xu Yi nodded and glanced into the room. "How's it going? Is Vivian okay?"
"The first person I asked when I came back was Vivian..." Akali muttered and turned away. "Come in, Vivian is upstairs. She probably isn't asleep yet. I'll call her to come down."
Seeing Akali turn around and run up the stairs, Xu Yi turned around and looked behind him, but did not find Yanis.
It seems that this female elf should have used the invisibility technique to hide her figure again.
Thinking that she had been following him all the way, Xu Yi couldn't help but hit his head with a headache.
The character of the elves is stubborn, and this Yanis is especially stubborn.
No matter what Xu Yi said, she just refused to leave Xu Yi's side, as if Xu Yi would disappear as soon as she left.
Xu Yi's persuasion was fruitless, his threats were useless, he wanted to get rid of her but couldn't, and in the end he had no choice but to accept this reality.
Fortunately, Yanis didn't like to show up in front of other people. She could use the invisibility technique to hide her figure at any time, but it wouldn't have much impact on Xu Yi.
Shaking his head and walking in, Xu Yi found that the living room was actually neatly tidied up, not as messy as every time he came here before.
Seeing Akali running down the stairs again, Xu Yi couldn't help but asked her in surprise: "Hey, Akali, have you changed your gender? You've actually started to learn to clean the house."
Akali glanced at Xu Yi with some resentment, and snorted softly: "Isn't it because Mr. Chairman, you always say that I don't clean up the house."
"If my words are so effective, that would be great." Xu Yi laughed and suddenly realized that something seemed not quite right. After thinking about it, he looked up. Then I found a yellowish transparent cylinder hanging with a ribbon on the roof of the living room.
There seemed to be something in the transparent cylinder that was emitting a strong light, but once it was filtered by the cylinder, it was dyed into a mild yellowish light.
The reason why Xu Yi felt something was wrong was because he suddenly remembered that it was clearly dark night outside. The room was very bright, like daylight.
If you rely on candle lighting, you will never achieve this effect.
After taking a look at the light yellow cylinder, Xu Yi couldn't help shouting in surprise: "Hey! You have actually succeeded in researching it!"
Akali narrowed her eyes and said with a smile: "Yes, President, this is our newly developed magic lamp, what do you think?"
Xu Yi raised his hand, only to find that the magic lamp was hung so high that he could not reach it.
Just when I was thinking about finding a stepping stone to take down the magic lamp and take a closer look, a chuckle sounded from the direction of the stairs. Evita's voice sounded.
"President, if you want to see the magic lamp, why not look at this one in my hand."
Xu Yi looked back and his eyes suddenly lit up.
On the stairs, Evita climbed down.
Maybe it's because it's late. At this time, she was wearing this set of loose nightgown. Although it covered her figure tightly, it added a sense of laziness, which gave it a different style and charm.
What caught Xu Yi's attention even more was the glowing thing held by Evita in both hands.
This thing has a wooden round base, and the upper end is a lavender transparent glass cover.
At this time, the glass cover was evenly emitting a light that was not very strong because it was blocked by the glass cover. It could only emit a hazy lavender light, covering the whole body of Evita holding it, actually adding a mysterious aura to Evita.
After Xu Yi took a look, he was even more surprised: "Evita, you have actually solved the problem of the strength of the magic circle?"
Evita smiled slightly and did not answer Xu Yi's question. Instead, she turned sideways and let out Vivian who was hiding behind her.
Seeing Vivian's shy and evasive expression under the lavender light, Xu Yi couldn't help but be stunned.
"Vivian, why are you hiding behind Evita? What? Don't you recognize me after not seeing me for more than ten days?"
Vivian quickly shook her head vigorously. After taking a look at Evita, she saw Evita nodded to her with an encouraging look on her face. Then she hesitated for a moment, moved down the stairs, and slowly came to Xu Yi's side.
Before she reached Xu Yi's side, her expression seemed very nervous. When she reached Xu Yi's side, she suddenly breathed a sigh of relief, and her expression suddenly relaxed.
Xu Yi looked at her 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?"
Vivian's cheeks, which were already rosy because she had just taken a shower, became even redder, and she shook her head vigorously.
"It's really hard to guess what the little girl is thinking." Xu Yi could only mutter in his heart, turned around and waved to Evita and Akali: "Come on, Evita, take the one in your hand Bring the magic lamp over and let me take a look. Akali, show me the results of your research these days and let me see how far you have gone."
When Evita came over with the crystal lamp, Xu Yi unceremoniously asked Evita to take apart the magic lamp. Not surprisingly, he found a very familiar magic circle on the base of the magic lamp.
But if you take a closer look, you will find that this magic circle is quite different from the magic circle on the base of the magic crystal that Xu Yi spent money to buy before or the magic circle that Evita later drew from memory. changes, it is obvious that Evita and the others have made targeted improvements to this magic circle.
Xu Yi looked at it for a while and discovered a difference in this magic circle, that is, the top of this magic circle was also covered with dense, thin weed-like things. Xu Yi carefully observed it and then recognized it. Although these weeds have changed color, they are indeed fluorescent grass.
Xu Yi thought for a while, stretched out his hand and pressed lightly on the fluorescent grass, and then found that under his gentle pressure, these thin fluorescent grass had several breaks.
Evita saw Xu Yi's movements. He wanted to stop him loudly but it was too late. Seeing Xu Yi break a few fluorescent grasses, he suddenly showed a wry smile.
"President, have you discovered the problem?"
Xu Yi raised his head and glanced at her. Nodding slightly: "This is a very common problem, not difficult to find. Haven't you guys come up with a solution?"
Evita shook her head helplessly: "Although fluorescent grass can emit light perfectly, it is just dead grass after all and is very fragile. No matter what we think of, it is difficult to ensure that it will not be destroyed by external forces. So you see, no matter Is it the magic lamp hanging on the ceiling or the magic lamp in my hand, the outside is wrapped with a glass cover, just to prevent the fluorescent grass from being damaged by external forces. "
Xu Yi nodded: "This is a good idea. The problem is that the limitations are too great. And we still have no way to extract all the air from the glass cover, or simply inject some inert gas into it to prevent the material from oxidizing. This design is definitely It won’t last long.”
Evita looked at Xu Yi in confusion. She didn't understand what Xu Yi meant by extracting air, injecting inert gas, and preventing oxidation of materials, but she knew that Xu Yi would never talk nonsense. So he didn't put forward any opinions, but silently wrote down everything Xu Yi said.
At this time Akali had already brought over all their research materials during this period, and Xu Yi immediately started reading them carefully after taking them.
The materials were very thick, and Xu Yi read them very carefully, so it took him more than an hour to finish them.
After reading it all, Xu Yi closed his eyes and thought for a moment, then said to the two of them: "I found that you two ignored a very important issue."
Evita and Akali were startled at the same time: "What's the problem?"
Xu Yi got up and came to the table. After touching the magic lamp that Evita had just dismantled, she fished out all the fluorescent grass in the magic lamp, and then asked Akali to bring a small bowl, and then broke these into countless pieces. Pour the fluorescent grass in and grind them into powder with a spoon.
Seeing Xu Yi's actions, Akali asked in surprise: "President, don't you think that fluorescent grass powder can also absorb the lightning in the magic circle to glow?"
"Why not?" Xu Yi asked, pointing to the materials put aside. "Have you noticed that there is a description in the information about fluorescent grass, which mentions that even after the fluorescent grass withers, it will still absorb lightning and emit bright light?"
"That's right. That's why we can use fluorescent grass to do this experiment. If we must have living fluorescent grass, we can't even develop these two magic lamps. But Sir, what does this have to do with your idea? ? Withered fluorescent grass is also fluorescent grass, but grinding it into powder is completely different, right?" Akali asked still puzzled.
Evita also looked puzzled, thinking that Xu Yi was a little bit fanciful.
Xu Yi smiled slightly: "Since the withered fluorescent grass also has the characteristics 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. In this case, There shouldn't be much difference between the formed fluorescent grass and the fluorescent grass turned into powder. Since it is theoretically possible, why don't we try it in an experiment? The so-called experiment is to find a way to succeed from ten thousand failures. ”
Hearing these words, Evita and Akali couldn't help but nod at the same time, thoughtfully.
At this time, Xu Yi had crushed all the fluorescent grass. Then he asked Evita to arrange a thunder and lightning array on the table, and then carefully placed the fluorescent grass powder according to the trajectory studied by Evita and Akali. The ground fell.
When everything was ready, Xu Yi glanced at the slightly nervous Evita and Akali, smiled, stretched out a finger, and a trace of magic came out.
There was a flash of lightning, and the thunder and lightning array was instantly activated.
After a moment, a faint ray of light emitted from the fluorescent grass powder covering the magic circle. It gradually became brighter in the blink of an eye, illuminating all the dark places on the table and also illuminating the surprise-filled faces of the three people around the table. Smiley face.
