After dinner, Yu Dian was on duty.

Cheng Yun went upstairs to change into a pair of sneakers that were easy to walk, put on a thick down jacket, put on a scarf and walked out.

Cheng Yan was washing dishes in the kitchen, and when he saw him come out, he couldn't help but be stunned, and asked, "Still going out so late?"

"yes, go out and buy something. ”

"Is little Lori going too?" Cheng Yan glanced behind him.

Little Lori was following Cheng Yun with great interest.

Cheng Yun looked back at it and said, "It's not going." I went out and came back soon. ”

Hearing this, Xiao Lori immediately raised her head and looked at Cheng Yun in a daze.

It was bored, and walked back in a state of interest.

Seeing that this human has changed his clothes and shoes, he thinks he is going to take him out to play!

Cheng Yan suddenly looked at Little Lori with wide eyes.

Tang Qingying, who was washing the dishes with her next to her, said again: "Look, this little thing really understands people's words." ”

Cheng Yan nodded: "It's really spiritual!"

Tang Qingying said with a blank face: "That's called a monster!"

After speaking, she looked at Cheng Yun again: "Brother-in-law, where are you going?" I'll finish washing it right away, I'll go with you!"

"No!" Cheng Yan immediately said in a cold voice.

"I accompanied Cai Qing out to buy a guitar, nothing fun. Cheng Yun also said.

"He can also play the guitar?" Tang Qingying was stunned.

"yes, that's a good play. ”

"He's better looking than Ben Yao, and he's still playing music?" Tang Qingying said dumbfoundedly, then glanced at Cheng Yan, and sighed, "We girls are simply uncompetitive!"

“…… I'm leaving. Cheng Yun walked out.

"Brother-in-law, you have to keep your sexual orientation!" Tang Qingying said uneasily.

Cheng Yan glared at her, and then also said to Cheng Yun, "It's cold tonight, so if you come back early, buy me two pot helmets to warm up." ”

Cheng Yun: "......"

In this day and age, mobile phone stores are everywhere.

There are also many piano shops near Yizhou University, and more than ninety percent of them sell guitars. After all, many college students are bored in the dormitory, and when the excitement comes up, they will want to learn a musical instrument and dream of making those innocent and seductive girls fall in love with themselves and then struggle with which one to choose, and the guitar is a very good choice.

Cheng Yun didn't do this when he was in college.

A Redmi 5,799.

I also got a card, fifty yuan.

The little mage didn't have a strong concept of the currency of this world, but he knew that his salary was around 2 or 3 thousand a month.

Nearly a third of it was gone, and he was still very distressed.

Although the hotel has food and lodging, who can not have some pocket money in their pocket? Seeing on the side of the road that there is no money to buy the snacks they want to eat, that feeling is really uncomfortable!

As soon as he walked out of the mobile phone shop, the little mage who was standing at the door of a pastry shop and couldn't walk thought so, and then he looked at Cheng Yun pleadingly, and said, "Station Master, I'm tired from walking for so long, and I consume a lot in winter, buy a cake to supplement a little calorie!"

Cheng Yun was speechless, so he had to buy him a cake.

Not long after, the two walked into a piano shop.

The little mage held the cake in one hand and a small wooden spoon in the other, and it took a long time to scoop a small bite into his mouth. He was reluctant to eat it all at once, after all, he had no money, and he didn't know when he would be cheeky to let the station master treat him next time after eating.

His eyes lit up as he looked at the guitar hanging on the wall.

"Can I try?" he said, looking at his boss.

"Yes. The boss nodded.

"Stationmaster, help me with the cake. The little mage turned to face Cheng Yun, handed him the cake, and then began to take off the guitar on the wall and play it one by one.

While playing, he asked the boss about the price.

The boss saw that although his technique was rusty and he was not very familiar with the posture of holding the guitar, he occasionally played a few notes and was very smooth and beautiful, so he did not quote indiscriminately.

Guitars near universities are generally cheap.

The little mage quickly fell in love with a guitar that the boss quoted for 1200, and without waiting for Cheng Yun to remind him, he skillfully began to bargain with the boss. One moment he said that this guitar had a noise, and another time he said that it didn't look good, and in short, he made a bunch of nonsense.

In the end, the guitar was sold for 800 yuan.

The little mage walked out of the piano shop with a guitar bag on his back, holding a cake in his hand, with a big smile on his face, and he felt that the world seemed to be much better.

"Stationmaster, which way are you going?" he turned his head to look at Cheng Yun.

But I saw Cheng Yun looking down and holding his mobile phone in a hurry to memo, and muttered in his mouth: "800+50+800......"

The little mage's brilliant face suddenly darkened: "Where are there two 800, obviously one is 799." ”

Cheng Yun glanced at him, ignored him, and quickly said, "By the way, there are still ten yuan." ”

"How can there be ten pieces?"

"You lost the bet to me. ”

"Uh......" The little mage's face was dark, and he only felt that if he wanted to eat cake next month, he would probably have to be cheeky enough to let the stationmaster have a treat, and this salary ...... It's really clearly arranged.

"By the way, I still have something I want to ask you!" Cheng Yun put down his phone and said.

"What's the matter, give me money?"

"Don't give money. ”

"What?"

"Have you studied the theory of space-time, especially space, the universe? Cheng Yun didn't rush to say.

"Space-Time Theory...... Space, Space, Space...... Why are you asking this?" the little mage looked at him stunned.

"Do you architecture mages want to learn this?"

"If you ask like that, our Mage in the Department of Architecture doesn't learn the theory of time and space. The little mage paused, "But the theory of time and space, male mages should dabble in a little bit of it, such as learning about it as a hobby, or learning a little bit about it from film and television works and popular science animations." But it's mostly something very basic and conceptual. ”

"Oh. Cheng Yun was a little disappointed.

"What do you mean, let me remind you, I'm a male mage!" the little mage said with a dark face, "And I'm very interested in what the ancient mages have to learn, especially since I'm still a scholar!"

"Huh?" Cheng Yun became interested.

"You probably want to know more about the universe. The little mage quickly guessed his intentions, and then said, "I've read a lot of books on time and space, and I took a course on time and space theory when I was in the Advanced Academy, but I thought it was boring and I just skipped it. However, because my money is always running away for no reason, I bought a lot of books, including many primers on the theory of time and space, recording the exploration of the universe by the sages. ”

"If your personal computer can wake up, right?" Cheng added.

"Yes. ”

“……”

"What do you want to do?"

"Didn't you guess it all, I want to learn something about the universe from you!" Cheng Yun said.

"Time and space?"

"Space is the mainstay. ”

"Time and space are not separate. The little mage said lightly as he ate his cake, "It is a common mistake for people who are ignorant of the theory of space-time to think of time as a physical object that can exist independently, and it proves that your understanding of time and space is still at a very primitive level of perception. ”

"What do you mean?"

This means the difference between ordinary people and scholars. Ordinary people rely on their own perception and imagination to judge a thing - they think it is so, it should be so...... Scholars are detached from ordinary people, and they judge a thing through rational calculation, research, observation, etc., and there are many things that are completely different from what we perceive. ”

"Sounds like a lot of power. ”

"Yes. The little mage glanced at him, "Although my level is low, if you want to study time and space from scratch, I will teach you more than enough." ”

"Really?" Cheng Yun's eyes lit up again.

"Yes, trust me. But in order to make up for the time and effort I spent explaining the theory of time and space to you, can you ......" the little mage squirmed a little, "can you lend me the Kunzhen Ball for research...... After all, I can get a lot of valuable knowledge from Kunzhen Ball, including the knowledge of space-time theory that you want. I can digest this knowledge and feed it back to you. ”

"You're disgusting. ”

"That ......"

"Give you a chance to express yourself!" Cheng Yun said.

"Thank you, webmaster...... Wait, I don't think I should say thank you. The little mage tugged at the corners of his mouth, scooped up another spoonful of cake and put it in his mouth, sipping it.

"Well, that doesn't seem to be the way back!" said the little mage, suspiciously.

"Well, buy a few pot helmets. ”

Back at the hotel, one person had a pot helmet, and the little Lori was also divided into one, and Cheng Yun took the little mage into the node space.

The little mage also moved to the small blackboard of announcements at the front desk.

So, in the empty node space, a small blackboard stands in the air. The two of them took off their coats and threw them aside, one stood in front of the small blackboard with a small staff like chopsticks, on which he randomly drew a circle to represent the universe, and the other sat leisurely not far away, as if there was a transparent rattan chair under the buttocks.

"Teacher Cai's class has started! This student, please take your posture correctly and take knowledge seriously. ”

“…… Hurry up. Cheng Yun said impatiently.

"Please respect the teacher. The little mage said in a weak tone, then pointed to the small blackboard and said, "In view of your novice level of time and space theory, stationmaster, let's start from the beginning of the universe. ”

"Hmm. ”

"Ahem, this student, please cooperate with the teacher more, and you can be more enthusiastic in class. "The little mage seems to have taken on the role.

“……”

"How the universe came to be, in fact, no one knows, and it is almost impossible for people living in the universe to know. All we probably know is how it got to where it is. The little mage pointed to the blackboard with his already repaired chopsticks staff, "A big explosion is the most common way to say it, but if there is nothing, a big explosion is impossible. And the universe is not unique, so you can't say that all universes came from the Big Bang. ”

"Hmm. Cheng Yun thought so.

A large universe such as the Earth Universe could still be formed by the Big Bang, but a hive universe composed of countless planes like the Panyu World could never be formed by the Big Bang.

And whether it is the world of the little mage or the earth, his cognition is actually very narrow, so he has the possibility of refuting many inferences.
