"But what does this have to do with 'Tangram'?" After listening to Heilong's words, Li Zijun became more and more curious about 'Tangram'!

"In the emperor's opinion, there are seven elements in this world: light, darkness, wind, fire, water, earth, and there is also an element that can change the physical quality of human beings, which we call 'fighting qi', and the emperor thinks that it is biased towards metal!"

"The Emperor used these different elements to form the 'Tangram'!"

"Don't understand?" Seeing Li Zijun, Heilong was still stunned, and couldn't help but ask.

"Do you mean to say that the 'tangram' is made up of seven elements, and it's not as we usually understand it, it's divided into seven parts?"

"It's made up of seven elements, and it's really divided into seven parts!" the black dragon nodded first, then he looked at Li Zijun and shook his head.

Black Dragon's statement made Li Zijun completely fall into contemplation, and after a long time, his frowning brows gradually stretched a little:

"The seven 'tangrams' represent the seven elements in this world, is the emperor trying to tell us that these seven elements are in the correct proportion in this world?" Speaking of this, Li Zijun suddenly felt a flash of spiritual light in his mind, and he immediately seemed to understand something!

"I see?"

"Don't say! Don't say!" The black dragon waved his hand, although only he could hear Li Zijun's words at the moment, he still didn't let Li Zijun put the secret of the 'tangram' into account!

"Now, it's my turn to make the third condition!"

"Wait, didn't you say I could ask three questions?" Li Zijun didn't forget the black dragon's promise to him, and he hurriedly stopped the black dragon dao.

"Boy. I seem to have answered more than just three of your questions, don't be too greedy!"

Li Zijun was stunned for a moment. Only then did he realize that he had asked the Black Dragon multiple questions before, although they were all around the 'Tangram'. But strictly speaking, the black dragon is indeed right. Thinking of this, he sighed softly and closed his mouth in a little disappointment!

Seeing that Li Zijun didn't argue anything, Heilong went on to say his third condition:

"I want three drops of your blood!"

"What, you want my blood, what do you want to do?" Hearing this condition of the black dragon, Li Zijun immediately became vigilant.

"What do you care about me?!Don't talk nonsense, do you agree or not!" The black dragon said and was about to put Li Zijun down.

"Wait!" Li Zijun hesitated, and finally stopped the black dragon.

"I can give you three drops of blood. But I need you to make a promise to me: you will never use my blood to do anything bad, let alone put a 'blood charm' on me and endanger my safety!"

"Who do you think you are? Do bad things with your blood? You can really lift yourself up! Three drops of blood can't endanger your safety, so you can rest assured that I will bleed!" The black dragon glanced at Li Zijun disdainfully and threw a small porcelain bottle in front of him.

"Really, not?" Li Zijun looked at the black dragon, still not sure.

"I swear to the great dragon god: I really won't endanger your safety, let alone do anything bad with your blood!" Although the black dragon acted indifferent, he swore in such a hurry, which still exposed his urgency in this matter.

"Bloodletting is very hurtful, what compensation do you give me this time?" Although Li Zijun noticed the change in the black dragon. But he also knew that he might not be able to give these three drops of blood today. And this doesn't mean that he can't continue to knock on the black dragon's 'bamboo pole', Li Zijun deliberately put on an embarrassed expression.

"I see that you unleash all kinds of magic in almost the same way, with reasonable technique and speed. But in terms of power, it's really not satisfactory!"

"Even your best martial arts, there is a lot of room for improvement in terms of understanding and skill! I have a book here that is a cheat book, which analyzes the characteristics of various elements in more detail. As well as some tips and tricks for using it. I think it's just right for you at this stage, and it should be able to help you improve a lot. If only you are willing to give me three drops of blood. It's yours!"

"Isn't it possible for you to properly ignore the 'damage' caused to you by bloodletting this time?"

"Really?"

"Huh!" Before Li Zijun's words fell, a thick parchment book had already fallen at his feet.

"See for yourself!"

Li Zijun hesitated for a moment. Stooping down to pick up the parchment. He tried to look through the so-called secret book, and it didn't take long for his face to change dramatically.

"Would you really like to give it to me?"

"Squeeze three drops of blood there, and it's yours!" said the black dragon as he raised his claws and pointed to the small porcelain bottle at Li Zijun's feet.

This time, Li Zijun didn't have any delay, and squeezed three drops of blood into the small porcelain bottle in an orderly manner.

"Finally, I have another request, I don't know?" At the moment of the result of the small porcelain vase, the black dragon, who had always been very strong, suddenly became hesitant.

"Please speak!" Li Zijun, who had already determined the approximate content of the cheats at this time, was full of affection for the black dragon, and he nodded to the black dragon almost without thinking about it.

"I heard that there is a perennial Wennuo river in the northern part of the Youlan Continent, can you help me get to its end?"

"I seem to have heard of that place, but I haven't had a chance to go there yet, I don't know where you asked me to go and what to do?" Li Zijun didn't know what the black dragon wanted, he lied here.

"You just need to wear this necklace and stay there for three hours!" said the black dragon, taking out a beautiful men's necklace and carefully handing it to Li Zijun.

"It's that simple?" Looking at the necklace in his hand, which obviously contained great power, Li Zijun asked the black dragon with a little puzzlement.

"It's that simple!"

"Don't you need me to meet anyone or say anything?"

"There shouldn't be such a possibility!But if someone really comes out to see you," Speaking of this, the black dragon paused slightly, and at this moment his eyes became extremely entangled:

"If someone really comes out to see you, she can say whatever she asks you!" the black dragon let out a long sigh and shook his head a little helplessly.

"And after that, I mean what else do I need to do? this necklace?" Speaking of this, Li Zijun's eyes were a little more greedy and reluctant.

"It's already yours! After that, whether or not anyone comes out to see you, you just have to leave!"

"Okay, I promise you!" Li Zijun pondered for a while and nodded solemnly to the black dragon.

"Thank you very much!"

"Can I ask one more question?"

"Don't you think you're a little greedy, boy?"

"I just want to ask about the whereabouts of the two of them! Of course, if you don't want to answer, you just don't ask me anything!"

"That woman acted as a sacrifice when the mirror world was activated, as for that young man, according to the agreement he reached with us before, he has been sent into the passage by us in advance, if there is no accident, you should be able to see him soon!"

"Are you satisfied this time?"

"You mean he's already returned to our world?" Li Zijun thought this was the most reasonable guess, but what he didn't expect was that the black dragon actually shook his head:

"Do you think the mirror world will be so simple? time is not enough, don't talk about him, even those of us 'people' can only stay here and quietly wait for the mirror world to open!"

"Wait until the mirror world is opened? Isn't the mirror world only open to the Demon Domain?" Hearing the black dragon's words, Li Zijun's face couldn't help but change slightly.

"Nonsense! There are two areas in the mirror world, do you know that?"

"Know a little bit about it!"

"Since there are two regions, how can the mirror world favor one over the other and only open to one side?!"

"Doesn't it mean that these two areas have been merged into one?" Li Zijun said as he looked at the black dragon, a little uncertain.

"Anyway, you're also a smart person, why don't you think about it carefully, how can two different spaces easily merge into one?

"Is there something wrong with what I said?"

"The deviation is big!'Mirror World', as the name suggests, is a world where 'mirror' and 'mirror' are separated and unified!"

"'Separation' means that we belong to different spaces, and 'unity' means that we are projected into the same world, that we are united in and outside the mirror!"

"You're saying you're all projected into our space now!"

"It's the other way around! You're being projected into our space! It may sound like it's a bit close to merging with space, but in reality, there's a huge difference. What really merges is the 'scene' inside and outside the mirror, rather than two different spaces inside and outside the mirror!"

"But one thing you think right, if you don't leave us in time, after seven days and seven nights, you will be sent to the Demon Realm!"

"So, wouldn't you also be able to borrow the mirror world to enter our Youlan Continent?"

"Theoretically, but we're never going to do it!"

"Why?" Li Zijun said as he looked at the black dragon with a puzzled face.

"The reason is simple: the gains outweigh the losses!"

"Speaking of which, I have to explain to you the 'fairness' of the mirror world! Those who actively enter the mirror world will have their power reduced by half, and those who try to cross space will have their power halved again. ”

"Take me as an example, after entering the Youlan Continent through the mirror world, my strength will be less than a quarter of what it is now, and at most I will only be a high-level martial artist!"

"What else can I do but die every day? Instead of being so scared, I might as well just 'wipe my neck' to be more happy!" said the black dragon, waving his big head disdainfully.

"I see!" After listening to the black dragon's explanation, Li Zijun nodded thoughtfully.

"Boy, you are indeed very smart, but you have a problem that I don't appreciate very much, but I like very much: you are very easy to trust people!" said him, and the black dragon raised his giant claw and lightly tapped Li Zijun's nose. (To be continued.) )
