At about two o'clock in the afternoon, Cheng Yan finished his afternoon nap and walked downstairs. She yawned while rubbing her sleepy eyes, "I'll go back and get a change of clothes first, and then I'll work again...... Huh?"

She looked at it and saw that Cheng Yun was sleeping soundly on the counter, without making a sound at all.

It's like dead!

Cheng Yan sighed helplessly, walked through the hall, pushed open the glass door and walked out.

The sun at the end of June was so scorching that she frowned, stretched out her palm to cover her forehead, and still swept her Mobike back on.

Almost as soon as she left, the old man happened to come back from outside with a shopping bag. Thinking of the shopping experience just now, the old man will still show a little embarrassment.

He glanced at Cheng Yun, who was sleeping on the counter, and carried his clothes upstairs, and when he came down, Cheng Yun had already woken up, and his face looked much better than before.

"Well, I'm back. Cheng Yun said hello.

"Hmm. The old master nodded, took out a few tickets from his pocket and handed them back to Cheng Yun: "This is the money left over from buying clothes, return it to you." ”

"Well, there's no need to be so polite......" Cheng Yun glanced at the ticket, and was suddenly a little stunned.

Good fellow, he seems to have given the old man a total of 400 yuan, after all, the clothes are cheap in summer, and he is not rich! As a result, the old man left him with more than 350 yuan......

"Where did you buy your clothes?" he asked.

"That city seems to be the capital of your country, let's call it Yanjing. Then there is a place called Xizhimen, there is a market in Xizhimen, I see that there are a lot of people squatting there to pick clothes, since it is so popular, it should be not bad. The old man said.

"Yanjing!!" Cheng Yun looked at the table below, and then continued to stare at the old master incredulously, "You went from Jinguan to Yanjing in two hours!!"

The old master smiled faintly and said, "Yes." You slept for two hours and your spirits seem to be much better than in the morning!"

"Really?" Cheng Yun was stunned, no longer entangled, and sighed, "It may have something to do with the sleep just now." By the way, I keep repeating the first step of meditation before I go to bed, and I feel a little tired after each meditation, but I immediately feel a little more energetic, right?"

"......" The old master was silent for a while, and then showed a somewhat embarrassed expression, "It's been too long since I was born, and I've almost forgotten it." However, the results should tell us something. ”

"Then when my sister wakes up and hands over the shift, let's move on to the next step!" Cheng Yun was a little excited, "By the way, what's the name of this meditation method?"

"Well, I think about it...... It seems to be the basic meditation method for beginners in the Iron Horse Kingdom, the seventh set, a simplified version. The old man's words extinguished all his expectations.

"......" Cheng Yun.

As if seeing the gloom in his expression, the old master immediately added: "But I have optimized it, and the meditation method is much more scientific than the meditation method implemented at the beginning, and the effect should be better." ”

"At the beginning...... It should be ......" Cheng Yun couldn't help but be a little silent, "The Iron Horse Kingdom is the kingdom that expanded to Yanhu hundreds of years ago, is it still there?"

"It's still there. The old master affirmed the strength of this ancient kingdom, "But it seems that it has been reduced to a third world country." ”

Cheng Yun squeezed out a far-fetched smile at him, immediately got up, and walked out of the counter: "You help me take a look, I'll go up and see if Cheng Yan has woken up." ”

As soon as he was about to go upstairs, he saw Cheng Yan wearing a sunhat and a big watermelon in his hand and pushing open the door from outside and walking in, looked at him, and said, "Awake?"

"Uh, when did you go out?"

"Just now. Cheng Yan said, glancing at the old man lightly.

"Then you come and guard, I'll go upstairs and rest first. ”

"Wait!" Cheng Yan shouted.

"Huh?"

"I brought you melatonin and sleeping pills, I bought them before and didn't finish them. Cheng Yan calmly took out half of the watermelon that had been cut in half and put it on the counter, inserted a spoon in the middle of the red melon, and then stuffed the other half into the refrigerator containing the drink, before taking out a small bag and throwing it to him, "The dose of melatonin is 5mg, you take one piece first and try it, if it's not enough, take two tablets." If you don't have sleeping pills, it's better not to take them, so I finally prescribed them. ”

"Okay. Cheng Yun took the medicine and went upstairs.

The old master followed him very calmly, while Cheng Yan stood in the cash register, looking at their backs, and a glimmer of light flashed in his eyes.

node space, Cheng Yun sat cross-legged.

"Master Faye, I think we can study the space-time nodes first, and then have a little time left over to learn meditation methods. Cheng Yun raised his head and said to the old man, he had lost most of his interest in the 'National Primary School Radio Gymnastics'.

"Good. The old master smiled and didn't say much, "Then let's study how to distinguish the energy recovery of traversers and props today." ”

"Hmm!" Cheng Yun was still sitting on the ground.

It had been proven countless times before that the old man's experiments did not require his physical cooperation, and in this space, it didn't make sense at all in what position he was in.

With a wave of his hand, the old man took out the big staff again, and paused twice at his feet—the staff that looked particularly angry seemed to have no effect other than to make the old man look more like a mage and to cooperate with some of his habitual movements.

"Let's start with a standard, set it up as a percentage, and then break it down to the energy scale. …… I can clearly perceive the total amount of energy and existing reserves of myself and the scroll, and you also have a certain ability to perceive the life and objects that enter this space, then it is very simple - as long as you confirm which part of the feeling you perceive is related to our energy, and then find out which part of it changes and correspond to the standard, it will be fine. ”

"Good!" Cheng Yun said.

"In previous experiments, I mostly shared the results with you, but this time you shared the results with me. "Maybe the old master will not need this research result in his life, but he just has a paranoid pursuit of knowledge.

"Good!" Cheng Yun said.

"Now I'm helping you to amplify your perception, and you have to remember every feeling you can feel. ”

"Good!" Cheng Yun said.

An hour passed.

"This research will be put aside today, it will not be completed in a short time, and we will move on to the next research project first. The old mage paused again, "I took the time to think about it last night, although I haven't had time to analyze and verify the formula, but I think your control over this space should be more than that, I think we can try to explore in this direction." ”

"Good!" Cheng Yun said.

"You're a ...... Alas!" the old man shook his head, "then let's get started." ”

"Okay!" Cheng Yun's expression was dull.

It was as if he had gone back to the old days, when he was in high school.

Teacher: Because sinB(sin²A+cos²A)=√2sinA, right?

Cheng Yun: Hmm.

Teacher: So sinB=√2sinA, right?

Cheng Yun: Hmm.

Teacher: Now the results are out, right?

Cheng Yun: Hmm.

Teacher: What is the result?

Cheng Yun: ......

About an hour and a half later—

"Well, that's all for today. The old master smiled and said, "You learn meditation quite quickly. ”

Cheng Yun sat on the ground and put away the meditation aid card, feeling that he was already a waste.

He looked up at the old master, but he didn't move, but asked, "Lord God, I'm actually curious, is there a god in your world? I seem to have heard you say the word demon. ”

"God, what is God?" the old man looked at him and smiled helplessly, "The original god was just an answer in people's hearts, and its purpose was to explain why the world and life are the way they are, and the reason for this is just a tool that people fantasize about filling the gaps in their cognition and eliminating their inner fears and fears. ”

Cheng Yun was stunned: "What about later?"

"Later?" the old man's expression became even more helpless, "You have to understand that any god in the broad sense does not exist, and any god in the narrow sense is not a god. We mages know this all too well. Because in the long development of our world, too many races and individuals who claim to be gods or who were once revered as gods have been pulled down from the altar by the rapid advancement of magical technology. ”

"That's it!" Cheng Yun frowned, "Then what kind of world is your magic world?"

"Our world?" said the old man, "Speaking of which, the background of our world is quite different from your world! The difference lies in the difference in subtle rules, so we don't have natural science, and it is difficult for us to give birth to natural science, because before natural science, we already had magic." We have a longer feudal era than you, those primitive wars we have lasted for tens of thousands of years, and then the development of civilization has changed everything, including magic and spellcasters......"

"Magic is no longer used to rub fireballs, and no one has formed a mage warband into a caster...... We began to use magic to make weapons, to create cities with magic, to build bridges across canyons and roads across deserts, to take us out of the planet and explore our plane with magic......" The old man looked at him and seemed to be a little fascinated by what he heard, and couldn't help but laugh, "But kid, these are just external differences after all. ”

"In addition to the difference in background, the climax and decline of culture, the rise and fall of war, the establishment and rise of the kingdom, and then to the ruin, kindness, greed, order, violence, rules, desires, these are always the same!" the old man looked at him and said, "People in two worlds are actually doing the same thing. I notice that people in your world also like to use a metaphor, the wheel of history, do you know why?"

"Why?" Cheng Yun asked, "Isn't it because the wheels will crush everything, and will leave everything behind and become the past?"

"Because the wheel is a circle, and the cycle repeats. The old master drew a circle in the air with his hand, and the white lines emerged, gradually evolving into the ancient style of the carriage wheel, and turning it suddenly, "When the wheel of history rolls and turns, even if it keeps moving forward, it is just a different era background to stage the same story!"

"Yes...... Really?" Cheng Yun narrowed his eyes at the dripping wheel.

He didn't refute, and he didn't have the heart to think about how to refute, even if he always found a flaw if he wanted to.

The old man has lived to be 1,200 years old.

A thousand years may not seem like a long time, but for ordinary people, it is tantamount to a long road with no end in sight. Therefore, ordinary people may never imagine what a spellcaster who has lived for thousands of years is like—how he thinks, what experiences and observations he has, more than we can imagine, or hopelessly pedant.

Cheng Yun didn't want to think about it because he was very sleepy.

The experiment with the old master helped him a lot, and he also learned the second, third, and fourth steps of meditation from the old master, and the old master said that he should be able to deal with it temporarily, and he wanted to go back and sleep and try it.

In order to avoid accidents, he helped the old man order takeout before going to bed, and chose to deliver it from six o'clock.

This move proved to be very sensible, because he slept straight into eleven o'clock at night, without dreaming or insomnia. When he woke up, he almost wanted to scream.

Insomnia is horrible!

It was also the first time he realized that a good night's sleep could be so comfortable!

It's a pity that I'm a little hungry.

When Cheng Yun stumbled down from the upper floor, he saw that Cheng Yan seemed to be entangled at the cash register by a young man about twenty years old who was dressed neatly and neatly.

Cheng Yun's sleepy eyes suddenly opened.
