"It's made of the refraction and reflection of light. The Demon King cleared his throat and said in easy-to-understand words.

There was no whip, but Sitina still created the conditions for herself to wave the whip of the little history brand, and "slammed" in the air and slapped the invisible blackboard, with an expression of "you are the worst class I have ever had", and continued to explain in more easy-to-understand words that even if the slime listened to it, he still had no reaction: "That is to say, I used my magic power to condense a huge piece, well, about this big." ”

The demon king stretched his arm as much as possible to draw a circle, and felt that the circle drawn by his current body really could not reflect the true size of the real thing very intuitively, so he had to withdraw his hand stupidly, pointed to the sky and said: " Huge ice cubes, but this is not an ordinary ice cube, but a new move that I invented after integrating my knowledge of optics, although it hasn't been named yet, but that's okay, in short, it's the huge ice cube that meets me after the opposite scene is illuminated by light, and it will reflect back and eat its own consequences. ”

Xiao Mo muttered in a low voice: "What is the meaning of self-retribution, obviously it will not have any effect." ”

Sitina raised her eyebrows and said, "What does it mean that it has no effect, then I ask you, what if you encounter an advertisement while watching the video?"

"Advertising?" Xiao Mo tilted his head and thought for a moment before replying, "It seems that all I watch are without ads, because it's a paid channel." ”

The Demon King was sniped in an unexpected place, so he had to indignantly express his disdain and contempt for the bourgeoisie in his heart, and then continued: "Then there are always times when you encounter programs that you don't like to watch, right?"

Xiao Mo held his chin, and then nodded emphatically: "Although you can learn a lot from the documentary of the bad old man, it is really annoying to watch it all the time." ”

Sitina breathed a sigh of relief, but she still pretended to have an expression of "I expected you to say that", and waved Xiao Shi, who didn't know when it turned into a feather fan again, and said, "What should I do at this time?"

Everyone looked at each other, and Mr. Lance didn't need to say that this kind of thing had always been done by the deacon, and the rest of them looked at each other with blank faces and almost asked each other, "Ah, you don't know."

"Tsk. The Demon King looked at Silver dissatisfied, looking at her with the eyes of a teacher looking at his most proud student.

Silver nodded and replied without changing his face, "What is the video? Can I eat it?" Silver was a little hungry. ”

“……”

The best student in the open class raised his hand to go to the bathroom, and Teacher Sitina waved his hand in hatred...... The feather fan, found that it was no longer a whip, so I had to fan it twice, and then said slowly: "Of course it's a change of channel!" That is to say, the light from the opposite celestial imaging is reflected back by the ice mirror like a mirror, as for why the ice mirror looks so big, it is the use of refraction away, in fact, it is not as big as it seems, but because of the optical illusion, it has a great feeling. ”

Xiao Mo whispered: "This behavior is not the same as changing the channel at all, right?"

"Why is it different, do you think that the ice mirror I set up is only used to reflect the opposite side? Then you are wrong, hum. The Demon King snorted and said, "This is a leap forward in the development of the slime industry, and it only needs to be powered on to transform the ice mirror into a big screen that can play movies." ”

Xiao Mo raised his head and looked at it, although it can be inferred from the words of the Demon King, the actual size should not be as exaggerated as standing in the sky, but at least there should be an ice mirror as high as a building, while secretly marveling at the strong strength of the Demon King, he said: "But ice should not be conductive, right?"

The little scientist waved his hand and said, "Of course ice doesn't conduct electricity, so you still need to install cables in the ice mirror, well, I think five kilometers long should be enough." ”

The corners of Xiao Mo's mouth twitched, such a big project is not so easy to do, and he doesn't even know where the edge is.

It's just that the Demon King said that it was very likely that it was Gnavelle who caused such a weather change, but now it is only separated, which really makes the rebellious knight who can't confirm whether there is a threat a little knotted, not to mention that the defense of such an ice mirror with entertainment function is still a question worth thinking about, if it is broken in the next moment, then you have to warm up first.

The princess of the kingdom, who also had knowledge of magic, frowned and asked Xiao Mo one step ahead of him, "Sitina-chan, although your magic power is very strong, can an ice mirror of this size really have enough defensive effect?"

Whether it is an ice wall or an ice shield, it is necessary to condense magic power to have excellent resistance to blows, this is the common sense that Laetia knows, and a huge ice mirror like Sitina is a huge version of the ice wall to put it bluntly, but even if the demon king's abundant magic power wants to condense such a huge ice wall, it should not be able to guarantee the defensive power.

Sitina smiled mysteriously and nodded, "The defensive effect is not for fun, but only after actually experiencing it. Saying that, the Demon King put Xiao Shi's glasses on the bridge of his nose, and then stretched out his middle finger...... Of course, she didn't mean to use the function of the middle finger most often, she just pushed her eyes, and then said coldly: "When did you have the illusion that I didn't use the mirror?"

"Clam?" Laetia looked dazed, but she still understood one thing, the Demon King seemed to be full of confidence in the ability of the Ice Mirror, and the fact that there was no sound of attack from behind the Ice Mirror could also confirm that the other side was shocked by the sudden change and did not attack, or that the attack had been launched but had no effect, but both of these two points were acceptable in either case.

So Laetia stopped talking, but began to ponder how to add drama to the brave master.

Yes, in order to let her master get more excellent character attributes in this fake play, Laetia took the initiative to increase the role for everyone, and all this was done without the knowledge of the brave and the demon king, and the reason for concealing the master is very simple, there is no need to say more.

As for the reason for concealing the Demon King, Laetia really can't guarantee that she can control a character like the Demon King who is comparable to the level of the actress and loves to add drama to herself at every turn, of course, whether she can hide it depends on whether the Demon King can find more interesting things on this island, but now it seems that the anomaly in front of her still makes the Demon King have a strong interest.

Laetia breathed a sigh of relief.

And this moment's laxity was finally captured by the Demon King.

See-through Sitina gave a meaningful look in her eyes.
