The Legend of Immortal Yun

"Diffusion effect? ​​How to understand this?" Sheyang asked curiously.

Li Yun was slightly startled. For him, a concept like the diffusion effect was as simple and natural as drinking water. He came to it as soon as he opened his mouth. However, it was not an easy thing to explain it to Sheyang, because this was originally the fourth generation of the universe. Concepts involved in super civilization.

If you want to explain it, you have to explain a lot of other things to Sheyang. This is not because Li Yun wants to hide his secrets, but because it is too troublesome...

"This... the effect of light reflection on rough and smooth surfaces is somewhat different..." Li Yun tried to speak as simply as possible.

"Reflection of light? Will the light be reflected back? It seems that a mirror can divert a little light, but it won't reflect back to the sun, right?" Sheyang asked suspiciously.

"Of course it's impossible! Well, let's not talk about light first, let's talk about these two items. Senior, do you think their surfaces are the same?"

Li Yun took out two pieces of fortune gold and showed them to Sheyang.

As soon as I hold Sheyang in my hand, I can't help but feel refreshed!

"What kind of items are these? Why do I think they are so special?"

"Senior, don't worry about whether they are special or not, just talk about their appearance?" Li Yun said.

"These... they all look similar on the surface, but the one on the left looks rougher to the touch."

"Senior, why not take a closer look with your spiritual consciousness and see what they are on the surface?"

"good!"

Sheyang observed it with interest, and soon felt a little uneasy!

"Impossible! How could there be such an item?!"

"Senior, what did you find?" Li Yun teased.

"The surface of the piece on the left is uneven and the arrangement is very irregular and varied. It is obviously natural! But I have never seen such an object that looks like gold but not gold. I don't know what its magical use is..."

"Where's the one on the right?"

"The right side... is smooth! Everything is smooth, smoother than the water surface, not even a single flaw!!!" Sheyang exclaimed in disbelief.

"Senior's power of spiritual consciousness is indeed powerful! Now, let's see what the difference will be when the same beam of light is projected on them..."

"You mean,

Let me shine my spiritual light on them? "

"No! It would be difficult to see the effect clearly. In fact, in the eggshell space we are in, the light is in a diffuse state, but it is difficult for us to detect it. So, what do you want to see clearly? It’s a diffusion effect, so it’s best to test it with a laser beam,” Li Yun said.

"Laser? What is a laser?!" Sheyang was stunned.

Li Yun was startled, and sighed secretly in his heart. If he pulled it out like this, he would have to pull out so many concepts. It would be too troublesome!

This is still communicating with a great wise man in this world. If he communicates with other people, he is afraid that he can't even talk about it!

"Laser is a type of light, but it still belongs to the category of light." Li Yun said simply.

Before Sheyang could react, he thought slightly, and the eggshell space was completely darkened. A beam of laser suddenly appeared and was projected on a piece of star luck gold on the right. The result can be clearly seen that this beam of light is incident. The angle is refracted!

"Senior, have you seen it? This is the effect of light shining on that smooth surface!" Li Yun reminded.

It was the first time that Sheyang saw this magical experiment. He was very excited and said loudly: "Yes, why can this light condense and not disperse?"

"Well said! This is a characteristic of laser. It is indeed very different from ordinary light." Li Yun praised.

"What is the difference?"

"Let's talk about this slowly later. Now look at the one on the left."

This laser beam hit the rough surface of Xing Yun Jin again on the left. She Yang made a "wo" sound, and he was a little excited again, because he saw that this beam of light was scattered by the surface of Xing Yun Jin. The situation was very different from the previous one. no the same!

"This situation is the diffusion effect! The diffused light will continue to diffuse when it hits other surfaces. If it is rough, it will continue to diffuse. Since the surfaces of many objects in the real world are rough, it will basically A diffusion effect occurs, so that even if the sunlight is just shining outside the window, the space inside the window will become brighter due to the continuous diffusion or scattering of sunlight..."

"So that's it..." Sheyang suddenly realized it, and was very happy that he understood another truth!

Moreover, more importantly, he saw Li Yun's experimental process. This method was something he had never been exposed to before, so it greatly broadened his horizons!

It can be said that seeing the experimental process is more meaningful to Sheyang than knowing the experimental results. If he can make good use of it, he can imitate this method, do more experiments, and explore more principles. Come.

Thinking of this, Sheyang said excitedly: "Thank you for your luck! I really benefited a lot today!"

"You're welcome! It's much better to communicate with a wise man than to play the piano with a cow!" Li Yun said with a smile.

"This..." Sheyang was startled, his face turned extremely red, his heart was beating wildly, he felt bad!

Because, in the communication process between me and Li Yun, I was almost like a bull, and Li Yun was the piano player. It was hard to understand something, but I was so excited that I couldn't calm down. The gap between the two was so big. Already? !

This made it almost impossible for him to muster the courage to ask questions again, because the more questions he asked, the more ignorance he would reveal.

Li Yun secretly laughed in his heart. Of course he wanted to seal Sheyang's mouth by saying this, otherwise he would chatter around him like a bird, and then he would stop working.

He didn't care about Sheyang. After finishing his work here alone, he returned to this eggshell space when he was about to leave. He found that Uncle Sheyang had been watching the sun through the lens, his expression a little dull...

"Senior, shall we go back?" Li Yun tried to ask.

But Sheyang seemed to have no reaction and was still in a daze...

Li Yun was helpless, his consciousness stimulated him, and he finally reacted.

"Ah? Xiao Lun, is the sun really burning? I'm really worried..." Sheyang asked loudly.

"So senior is worried that the sun will die? In fact, you don't have to worry at all. Didn't I tell you a long time ago? It can burn at least ten times longer." Li Yun comforted.

"But...even if it takes more than ten times as long, what will we do if it burns out?!"

"Find a new one. Maybe you can leave there before it burns out!"

"Leave there? Without the sun, we may have nowhere to go! Besides, even if we can leave, what about the other lives in this world? Will they all be doomed?" Sheyang asked.

"This...if their abilities have not evolved and no one else comes to save them, then this may be the fate waiting for them..." Li Yun sighed.

"What?! This is going to be a big problem!"

"Senior, there is nothing we can do about this. Because for some people from low-level civilizations, their fate is to be annihilated in the dust of the universe together with civilization, waiting to be replaced by new civilizations. In this universe, like this Maybe too many things have happened..."

"Oh my god!!!" Sheyang was stunned when he heard this, and his expression changed drastically!

Li Yun continued: "If people of low-level civilization want to change their destiny, they must make a comprehensive breakthrough, cross the huge gap in front of them, and enter a higher-level civilized world, so that they have the opportunity to continue to survive and develop. Until the end of that new civilization..."

"Xiaoyun, how do you know so much?! Can you help us achieve such a breakthrough?" Sheyang asked excitedly.

"Well... I'm still making progress right now. I don't know much about it. As for helping you, I'm not that big-hearted. Maybe I want to ask you for advice..." Li Yun said quickly.

"No! No no! I can already see that your knowledge is much higher than ours. Even the prophets in our clan cannot know more than you! You have even simulated our ultimate form. But we ourselves have no idea, not even any direction! What I have seen and heard from you these days shows that I am not even qualified to be an apprentice in front of you! I have decided, I want to study under you and lead our Sun Clan to make progress together in the future!"

"What?! This is absolutely impossible! This is absolutely impossible!!!" Li Yun's hair stood up all over his body when he heard this, and he immediately refused!

"What I decide cannot be changed! Even if you refuse to accept it, I will definitely follow you!" Sheyang said loudly.

"You?! Senior, you are just two rays of spiritual consciousness, and you are about to betray Uncle Sheyang's body. How can this be done? Isn't this hole dug too big?" Li Yun reacted and teased.

"This...if the main body had the same experience as me, it would definitely make such a decision! Because our thoughts are basically the same." Sheyang was startled and argued.

"That's just the senior's idea. Your body may not necessarily have the same idea. I've seen this happen many times." Li Yun said with a smile.

"Okay, no matter what my true identity decides, I have decided to follow you from now on!" Sheyang said shamelessly.

"Senior, I can't stop you from making any decision. However, I have many things to do and many cultivation tasks. It is impossible for me to be with you often so that you can get more benefits. Moreover, I may not always do what I say. It's better than the Tao of your True Yang Clan, so I hope your expectations won't be too high, so you won't be too disappointed in the future!" Li Yun said tactfully.

"No problem! I believe in my own vision and judgment. Even if I am really wrong, I will not regret it. Don't worry!"

"I still hope that senior will think twice and rush back with the chaotic matter as soon as possible, so as not to delay your research mission. If he can't study how the sun was born and can't participate in the clan competition, won't it be troublesome?"

"This... just like what you said, if he keeps researching in the wrong direction and doesn't look back, then you might as well let him study it later and wait until I bring you to meet him..."
