"Dreaming?" Mu Yin looked at him in surprise.

"Yes. ”

Cheng Yun briefly described his ability to dream, which was a little embarrassing.

Mu Yin's ability can be said to be against the sky, he can almost completely copy the time and space visitors, compared to his own ability, the difference is too big.

Mu Yin nodded after hearing this, glanced at him again, smiled slightly, and said indifferently: "Actually, there is not much difference, these abilities are just an aid, and they only help us a little in the early stage." You'll soon learn that mortals, no matter how powerful they are, are nothing to us. And you're going to surpass them very quickly, on a big level, and it doesn't make a difference whether you have these abilities or not. ”

Cheng Yun tugged at the corners of his mouth: "When you say mortals, you mean ......"

"Except for us, all mortals. ”

“…… Awesome. ”

"Huh. Mu Yin smiled.

Little Lori soon didn't want to run, so she ran back to Cheng Yun's side, jumped on Cheng Yun's lap, lay down against his stomach, and stretched her head to look at the content on his phone.

Cheng Yun is paying Cheng Yan, she bought a small bottle of sunscreen, as well as a repair cream and a hydrating mask.

Pay next to each other.

After paying, he looked at Mu Yin again.

Mu Yin was standing on the edge of the rooftop, his hands pressed on the railing, looking up at the sky slightly.

In the evening, the sky had gradually darkened, and there was only a hooked moon hanging in the sky, which was a little dim, but there were no stars to be seen.

But in Mu Yin's eyes, the space measured in light years seemed to be skipped, and in front of his eyes were the vast starry sky—rotating constellations, glowing and shimmering nebulae, exploding stars, black holes that had just formed, and even another civilization on the other side of deep space......

What a beautiful picture!

Once upon a time, his universe was like this......

Bustling, noisy......

Suddenly, Mu Yin sighed.

He tilted his head slightly, and the space that had been skipped returned to his eyes—a regular string of small black dots moving not far from here.

Only a moment later, Mu Yin smiled slightly, turned his head to Cheng Yun and said, "I found something interesting. ”

Cheng Yun kept looking at him: "What?"

"Guests. ”

"Guest?"

"A fleet. Mu Yin said lightly, "I don't know why, it seems to be moving towards you." ”

"A fleet?" Cheng Yun frowned suddenly.

"Yes. ”

"What kind of fleet?"

"See for yourself. Mu Yin waved his hand, and a picture appeared in the air out of thin air.

Cheng Yun first looked around before looking at this picture.

In the background of the picture, a dark universe is faintly visible, and a large fleet is sailing through the starry sky. There were about forty warships in the fleet, all of which varied in appearance, with a faint yellow glow from their tails, because there was no suitable reference and it was not known how large the ships were.

"Are you coming this way of us?"

"It's in this direction. Mu Yin made a little joke, "Maybe I'm here to have a friendly exchange with you." ”

"I don't think so. Cheng Yun was still frowning.

"Be optimistic, little one, and maybe come to worship you. Mu Yin said with a smile again.

"I'm not you. Cheng Yun said helplessly.

"That's what gives you experience. Mu Yin said again.

"Maybe......"

Cheng Yun didn't say anything more, just wrote down the incident.

If there is really a fleet that is not good, Cheng Yun is really not afraid of them as long as he calls for the node space.

Mu Yin seemed to remember something again, and said, "Do your relatives and friends know about this?"

Cheng Yun was stunned for a moment, and then replied: "I don't know." ”

"Oh. ”

"What's wrong?"

"I just remembered and asked. Mu Yin waved his hand and said, "I ...... at the beginning."

"What happened to you in the first place?" Cheng Yun found that there was no follow-up halfway through his words.

"I ...... I can't remember. Mu Yin frowned deeply, as if he was a little sad, this was the first time he had shown such an expression since he had been in the Earth Universe for so long.

"Can't remember?"

"Well, I seem to have lost a lot of things. ”

"Why throw it away?"

"I forgot about it, probably because of my brain convulsions, and the thoughts of my youth are always incomprehensible when I think about them at this time. Mu Yin was still frowning, "The first time and space visitor I saw, my best friend at the beginning, my parents who gave birth to me, my relatives...... Even the offspring I gave birth to, in fact, I can't remember many of them. I...... I haven't thought about it for years, I haven't thought about it like I do now. ”

After speaking, he looked at Cheng Yun again and said: "When people are young, in a certain period, in a certain mood, when they encounter special things, they will always make certain decisions that they will regret later. ”

"Taught. Cheng Yun was silent and said.

"I'm just sharing my feelings with you," Mu Yin shook his head.

At the same time, there was a knocking sound.

Cheng Yun turned his head to look, only to see the little mage standing at the entrance of the building, knocking on the edge of the door frame with his hand, and looking at them cautiously: "Stationmaster?"

"Huh?"

"Can I come here?"

"Of course. ”

"Oh. ”

The little mage came over, he glanced at Mu Yin, and said very friendly: "Hello, my name is Cai Zhifei." ”

Mu Yin smiled, "Hello." ”

The little mage glanced at the little Lori who was lying on Cheng Yun's lap and wagging her tail, staring at her tail blankly, as if she was thinking, 'Why does this thing move', and said, "Her Royal Highness Little Lori is also there", and then looked at Cheng Yun inquiringly, and glanced at Mu Yin's direction.

Cheng Yun was a little helpless, and introduced Mu Yin again: "He is also from another world, a trainee mage." ”

The little mage frowned: "Please remove the word apprenticeship!"

However, Mu Yin said very gently: "It's a spellcaster." ”

The little mage immediately smiled, took a dried sweet potato from Cheng Yun's coffee table, and said to him, "You see how good people can talk!"

Cheng Yun smiled at him: "Of course, he has lived for tens of billions of years after all." ”

"That's right...... What!?"

The dried sweet potatoes that the little mage had just put into his mouth fell to the ground: "How many years?"

Little Lori turned her head to the side, stared at the dried sweet potato he fell to the ground, and looked up at him again: "Woo......"

"I haven't introduced you yet. Cheng Yun pointed at Mu Yin, "This is Mu Yin from the Mu Yin universe, a master of time and space, but the difference with me is that he has lived for tens of billions of years...... Maybe longer. ”

“……”

Another thing fell to the ground.

It's the chin of the little mage.

This time it wasn't just the little mage, but the little Lori also opened her eyes wide, round, and stared blankly at Mu Yin.

Mu Yin turned his back to the railing and looked at Cheng Yun with a smile, as if he could see his bad taste.

Reacting to this, the little mage confirmed, "Really?"

"Well, he just came over to knock on the door. ”

"Shhhh

For the next five seconds, the little mage's mind almost shut down, and all that kept echoing was 'I ate at the same table with a Dacheng master of space', 'I poured Sprite for him'......

Cheng Yun was very hurt when he saw this-

Isn't Lao Tzu also the master of time and space?

After reacting, the little mage looked around, quickly grabbed a handful of dried sweet potatoes from Cheng Yun's coffee table, bent down slightly and handed it to Mu Yin on the side: "Your Excellency, please eat dried sweet potatoes......"

Mu Yin took the dried sweet potato: "Thank you." ”

"You're welcome. ”

At this moment, the little mage seemed to be possessed by Zhu Jiayan, and stood respectfully on the edge of the wooden shade, his eyes shining, as if he had seen a great temptation: "Your Excellency, may I ask you a few questions?"

"Of course. "Mu Yin easy-going way.

"Enmm......" Mu Yin agreed so quickly, which made the little mage a little confused, because he hadn't thought about what he wanted to ask at all.

But the little mage's reaction was still very fast after all, communicating with a Dacheng master of time and space, this kind of opportunity could make any mage in the Kunzhen world crazy, and he quickly came up with a question, which Cheng Yun also asked: "How can we humans break through the shackles of lifespan?"

Mu Yin had a very gentle answer.

But it's a little different from what he said to Cheng Yun last time, some places are more superficial, and some places are more profound.

Mu Yin directly pointed out the specific rules that control the lifespan of living beings, including the hypothetical evolution process of this rule, which made the little mage listen to it with fascination. He also pointed out a general direction to the little mage, but as for how to break through the 'shackles of lifespan' that the little mage said and reach a higher lifespan approaching the upper limit, he did not directly tell Cheng Yun the method of reaching the upper limit of lifespan like he did to Cheng Yun.

It took a whole handful of dried sweet potatoes, and the little mage naturally didn't waste this opportunity, and he quickly thought of one question after another...... Some of them are difficult problems that have plagued the academic community of Kunzhen for a long time, and some of them are of great personal interest to him.

The structure of the cosmic barrier, the separation process of chaos and space, and the origin energy at the beginning of the universe and its reverse synthesis......

Mu Yin's answers are very simple, but they can also satisfy the little mage.

After a few moments, the little mage seemed to finally feel a little embarrassed, he took a deep breath, and said, "One last question...... Have you calculated a model of the universe?"

Mu Yin frowned, and then looked at Cheng Yun on the side, and then said, "This problem is too big." ”

The model of the universe involves everything in the universe.

From the basic structure to the laws of operation and all the parameters, if you can understand the model of the universe, you can understand everything about the universe. But human beings will never be able to go this far, and there are many rules in the universe that restrict human beings from going this far, and the upper limit of life span is only one of them.

Mu Yin would never tell a mortal about it anyway.

Otherwise, it will either cause great damage to the universe, or it will lead to the madness or even the destruction of a civilization.

The little mage is still not giving up: "I'll just take a look." ”

Mu Yin still shook his head: "No." ”

The little mage hesitated for a moment, the glint in his eyes flickering, and he seemed to understand something.

Then there is a long struggle with hesitation......

Finally, he gritted his teeth, and had already made up his mind: "As long as I can look at the model of the universe, I promise not to pass it on, and I am willing to die in a very short time to ensure that this secret is not revealed." ”
