"Do you know how big it is?" Li Qingyuan suddenly said to Zhen Han.

??? Zhen Han was also taken aback by the old man's words, and only relieved after a while, this should be called himself, what day is big? Zhen Han didn't quite understand the meaning, but after thinking about it, he replied: "Eh, that master, the sky should be more than six million meters high, if you calculate its volume according to pi, it is... ”

???“ What?" Li Qingyuan was stunned by Zhen Han's answer, and said?

Originally, Zhen Han planned to calculate the volume of the sky, but before he finished the calculation, he was directly interrupted by Li Qingyuan, and the two were not on the same channel at all.

In fact, you can't blame Zhen Han, I don't know how to answer how big you are, and Zhen Han has recently been enchanted with junior high school textbooks, which can be regarded as putting what he has learned into practice.

In the end, Li Qingyuan will also come to his senses, and understand that this young man doesn't understand what he wants to ask at all, of course Li Qingyuan knows mathematics, and he also knows how high the sky is, but he didn't ask this.

"Apprentice, it's not this that the master asks you, what the master asks about your opinion of this world, and how big this world is. Li Qingyuan tried to explain to Zhen Han.

??? Isn't this a meaning? Zhen Han didn't quite understand what this old man wanted to express, Zhen Han still thought that this old man was going to test himself?

Zhen Han thought for a moment and continued to answer: "Master, the place we are in is in a solar system in the Milky Way, there are eight planets in the solar system, and we are on the third planet from the sun, on Earth, how big that day is, I don't know, it should be very large, the unit should be at least light years converted, I haven't learned there yet." ”

Hearing Zhen Han's answer, Li Qingyuan almost choked back his internal injuries, it seems that this kid doesn't know what he's asking at all, has the outside world changed so much? Do you know the Milky Way, and what the hell is light year? Li Qingyuan felt that he was a little out of touch with the world, and he hadn't been out for fifty years.

"Hey, apprentice, I'm not asking about this, forget it, I'll talk about it myself, do you know that our world, that is, the solar system you just said, forget it or say it smaller, it's our earth, do you know what it contains, what its rule system is?" Li Qingyuan thought about it and continued to ask.

What does the earth contain? This question is so abstract, what is the system of rules? Does this mean the rules of physics?。。。 That's a lot of fun, and if you do, you'll have to say it for a long time.

Zhen Han finally thought about it and replied: "Master, the earth contains a lot of things, and there are many things that humans have not discovered, and there are more than 10 million species found now, from the blue whale in the sea to the microorganisms such as viruses, and I can't say a lot, but when the time comes, you can check it on the Internet to know, the rule system, there are a lot, such as gravity, gravity, by the way, and the recently discovered gravitational waves." ”

What Zhen Han said made Li Qingyuan lose his temper suddenly, there are many things that Li Qingyuan doesn't know at all, check it on the Internet? What the hell is that? Look it up, are there so many species on the earth? The blue whale in the sea Li Qingyuan knows, but what is a virus? And what is the gravitational wave in the rules?

Originally, Li Qingyuan was going to ask Zhen Han about his understanding of this piece of heaven and earth, of course, Zhen Han's answer was not wrong, Li Qingyuan wanted Zhen Han to understand how big the sky is and how small he is, originally wanted to guide Zhen Han to understand that life is too fragile, and then a series of guidance to let Zhen Han understand some of the circumstances of the evolutionary.

But what I didn't expect was that I would make this apprentice stunned, has the outside changed so much? At the beginning, Li Qingyuan traveled around the world and saw that human beings had invented a lot of things, especially the steam engine, and Li Qingyuan felt that it was like that after a general understanding, he didn't feel anything.

As for the guns and cannons, they were made from the leftovers of the ancestors at that time, that is, they were surprised that they had a complex structure, and these guns and cannons didn't cause much damage to Li Qingyuan at that time, so they didn't do it.

"Okay, that teacher will go to the Internet to check, you don't need to say it. Li Qingyuan had no choice but to interrupt.

Zhen Han also stopped, I really couldn't understand what this old man wanted to ask himself?

Li Qingyuan was silent for a long time and finally decided to jump straight to the topic, let's not talk about the others, the outside world is changing so fast, and there are the rules of gravitational waves just now, it seems that he has to go out to understand it, compared to the previous rules, the new rules are born, it seems that human beings have a good understanding of the new rules, and they should really go out to understand.

"Apprentice, what do you think of internal strength?" Li Qingyuan thought for a while and asked.

"Ah, the internal strength is very powerful, one palm can kill a cow, and it can also point points, making people unable to move, oh yes, and that light skill, can the master teach me light skills? I have liked light skills since I was a child. Zhen Han was originally just guessing, but now that the old man asked directly, Zhen Han was even more excited, and hurriedly said.

Zhen Han used to be a fan of martial arts, and he loved what light skills there were, and he especially liked it, and even sometimes Zhen Han learned to meditate with people on TV, and then hit the grape leaves in the distance with one palm, if there happened to be a wind blowing, the leaves moved, but Zhen Han was excited, thinking that he had succeeded in cultivating internal strength.

Li Qingyuan didn't feel anything at first, thinking that there was still a magic of internal strength outside, but when he heard Zhen Han say some acupoints, he felt that something was wrong when he couldn't move, and finally Zhen Han said light work, and finally moved back, otherwise I don't know how much this style of painting is crooked.

"Apprentice, our cultivation of internal strength is not to fight and kill, but to stimulate potential, so that we can continue to evolve, as for light gong, after you accumulate enough internal force in your body in the future, teach you the teacher if you use the internal force to transport the mental method to your feet, then you will practice more, this is not in a hurry. Li Qingyuan finally found a channel to talk to Zhen Han, and he also had confidence in his heart.

"Then when I teach you the internal exercises, I need to explain a few things to you, and you can remember them. Li Qingyuan said.

When Zhen Han heard that he was about to obtain the internal exercises, his whole person trembled with excitement, for a person who is a fan of martial arts, there is nothing more exciting than this.

"First of all, because you are an adult, your meridians have been formed, so you can't refine too much essence every time, otherwise it will be easy to damage your meridians, and you have to spend most of your time every day to nourish your meridians with essence temperature, and there are other problems that will be said after the teacher teaches you the exercises, now listen well. Li Qingyuan explained the steps of refining the essence, and then a few meridians and a few acupuncture points.

Refining is actually very simple, that is, sitting down and meditating, by concentrating the mind and the bottom of the heart, there will be a faint sense of qi at this time, but what kind of meridians, acupuncture points, Zhen Han doesn't know at all, and he doesn't know where they are.

Originally, Zhen Han was going to ask, but then I thought about it and took out my mobile phone to check it, the signal here is not too good, but it is no problem to check the information.

Li Qingyuan saw Zhen Han take out his mobile phone a little inexplicably, and then saw Zhen Han open the mobile phone and check it, and then Zhen Han found out a map of the meridians of the human body, this scene surprised Li Qingyuan, what is the thing in this apprentice's hand? So powerful, I originally planned to say the meridians of the human body, and then guide Zhen Han through my own internal force, so that Zhen Han understood the location of the meridians and acupuncture points, but I didn't expect Zhen Han to use his mobile phone to find it out directly.

Li Qingyuan is becoming more and more curious about the outside world.
