When he returned to the room and looked at Jiang Li, seeing that he was still sleeping with a slight snoring, Li Nuonan exhaled lightly, returned to his bed, covered the thin quilt tightly, and then began to fall asleep. Pen fun and pavilion www.biquge.info

And Jiang Li, who he didn't notice, suddenly opened his eyes, glanced at him, shook his head, and then closed his eyes again.

Early in the morning, the sun shines through the window, and it is a bit dazzling. Li Nuonan reflexively took his hand to block it, but soon, he felt that this was not the bed he was used to sleeping in, and sat up from the bed with a shock.

"Awake?" Jiang Li sat on the tea table and glanced at him.

Li Nuonan didn't know why, he first looked his clothes up and down, and saw that they were all as strict as before going to bed, so he calmed down and said, "Wake up." Why are you so early?"

"I don't need to sleep too long. Jiang Li replied.

After saying this, he continued to play with one of the things in his hand. Li Nuonan didn't pay attention to it for the time being, got up and washed up first, cleaned himself up, and then went back to clean up the bed.

"Huh!" Li Nuonan finally noticed the extraordinary object in Jiang Li's hand at this time, and saw that it was a black spar, with a layer of luster flowing on it, very textured, and he knew at a glance that it was not an ordinary stone. His body shook, as if he had thought of something.

"Do you know this spar?" Although Li Nuonan's expression changed slightly, he still caught it for Jiang Li, so he asked.

Li Nuonan frowned lightly and said, "I'm not sure, otherwise, you can take a closer look at me." ”

Jiang Li didn't doubt that he had him, so he threw it directly to him.

This spar was obtained from the Yin family's treasure house, there were only a few pieces in the entire library at that time, Jiang Li was sure that they were not mortal, but his knowledge was limited, and he hadn't figured it out for a while.

Li Nuonan put the spar in his hand and rubbed it, the more he touched it, the more he couldn't put it down, that kind of warm and mellow touch, where can ordinary stones have, even people who don't understand it at all know that it is not simple.

He already had an idea in his heart, and he injected his true qi into the spar, and suddenly four colors of light were stimulated in the spar, and four huge energy were constantly fluctuating.

"That's right, this is the Four-Element Black Crystal!" Li Nuonan exclaimed in surprise.

"Quaternary Black Crystal, what is it?" Jiang Li asked.

"Haven't you heard of the Four-Element Black Crystal?" Li Nuo gave Jiang Li a strange look. Jiang Li nodded helplessly, speaking of the common sense of the mainland, he is indeed very bad, he has a chance to make up for these foundations, otherwise he will suffer a lot.

Li Nuonan saw that he really didn't understand, so he explained: "The four-element black crystal is actually an energy crystal naturally condensed by the mixing of yuan qi according to the rules, which is combined with pure heaven and earth essence qi, spiritual energy, elemental body, and alien energy, which can directly absorb the energy that cultivators need and transform it into internal qi, which is an extremely luxurious cultivation treasure!"

Jiang Li heard something about it, being able to condense the pure external qi between heaven and earth into such a high-density spar, I am afraid that the energy contained in it is very large, and asked, "How can you say that it is extremely extravagant?"

Li Nuonan said: "First of all, because this four-yuan black crystal is very expensive, it costs at least 30-500,000 mixed yuan coins for a piece, and it is difficult to see it in the market. It's still expensive, if you use it to absorb energy for cultivation, it will be very fast to enter the realm, but because it contains four kinds of energy, and ordinary cultivators only need to absorb one, three-quarters of the energy of Black Crystal will be wasted. But even so, the energy it can provide is considerable, much stronger than the cultivation that usually relies on simply absorbing external qi!"

"Can you only absorb a quarter of the energy?" Jiang Li still understands this, in fact, the formation of this four-element black crystal is very similar to the mixed element spiritual liquid, and most of the energy forms of the mixed yuan continent need to be combined according to the rules and proportions of the mixed element qi, otherwise it cannot be truly formed and stabilized. Jiang Li guessed that using this four-element black crystal to cultivate must be done in one go, absorbing a quarter of the energy of a spar at one time, otherwise only absorb some and put it aside, the ratio of the four energies inside the black crystal will be biased, and it will soon collapse.

"It sounds like a good thing, do you know what other uses it has?" Jiang Li asked.

Li Nuonan said: "There are really not many people who use it for cultivation, because it is too loser, at most it is some very big forces, and the background is amazing, so they will use these black crystals to absorb them, of course, even if they are them, they can only provide some seedlings with amazing talents, otherwise they will not be able to bear it." I've heard that its biggest use is to refine the mixed element spiritual liquid and support the operation of the formation, such as the teleportation array, if it is a relatively short-range distance, it is generally used black element ore, but when the distance is very large, such as cross-border teleportation, then it must be used Four-element black crystal, and black element ore is not good at all!

I have also heard of some top schools, such as Wang Ting and Fanli, the two most famous top universities in the East and West Continents, there will be large-scale cultivation formations in them, they use the four-element black crystal as the energy stone, in fact, the most efficient use of the four-element black crystal, it is estimated that it is this kind of big array, because there are students in various cultivation directions in the school, the four energies of the four-element black crystal can be fully used, of course, to be able to make this kind of big array, and even the power to smash the four-element black crystal like this, there are not many in the whole continent! I think refining the mixed element spirit liquid is estimated to be able to use the energy of the four-element black crystal very efficiently, of course, I am not familiar with the methods of the spirit liquid refiner, and I am just guessing!"

Li Nuonan said a lot, Jiang Li felt that it was still very reasonable, and his so-called tour guide had made some contributions now.

Jiang Li suddenly had an idea about the use of the four-element black crystal, but he didn't want to test it in front of Li Nuonan, so he continued to ask: "It sounds like this kind of black crystal is very good, do you know if there are these crystals in the real ruins?"

Li Nuonan was surprised when he heard that he wanted to buy a four-yuan black crystal, and said, "You have so many mixed yuan coins?" A piece of four-yuan black crystal will cost 300,000 mixed yuan coins when it is the cheapest and very lucky, and if you buy a few pieces, it will be a million dollars, and it is not surprising that Li Nuonan is so surprised.

"It's not rich, but this four-yuan black crystal is of great use to me, and it's no problem to save a few dollars. Jiang Li said this, not to mention the idea of using the four-element black crystal in his heart, since he would also need this kind of crystal when refining the mixed yuan spiritual liquid in the future, Jiang Li would naturally be as good as possible. He still has a lot of money in his pocket, enough for him to buy some.

Li Nuonan once again re-examined Jiang Li, when he first saw him, he was bargaining with the soldiers at the city gate, and he also tried to be cheap in terms of food and housing, and he couldn't see that he was a wealthy person at all. I didn't expect him to casually say that he would save a few pieces of four-element black crystal. Then his net worth must be at least a few million mixed yuan coins, otherwise it would be impossible to come up with such a large share to buy Black Crystal.

"I don't dare to say in other places, there is really this kind of black crystal sold in the real market, I have seen it in the small black market. In the real ruins, the most miserable life is the one who has no cultivation, and there are people with relatively low cultivation, for the real strong, this is a good place to pan for gold, where dragons and snakes are mixed, there are all kinds of evil people, and at the same time, any treasure may be circulated. This is also a good place to eat black, of course, provided that your strength is strong, strong enough!" Li Nuonan said.

"Is there a small black market?" Jiang Li became interested. For Li Nuonan's later words, there is also overlap with his thoughts, which is why the real ruins are in such a desolate area, and they have not fallen for thousands of years.

"Where is the place where the most powerful people live here?" Jiang Li asked again.

Li Nuonan pursed his lips, his action was very charming, fortunately Jiang Li didn't look at him, otherwise he would have to scold him like a girl, and said: "In addition to the black market, it is probably the martial arts arena, which is not only the place where the most powerful people gather, the most chaotic, and the most violent and bloody in the real ruins, but also the place where the most money gathers, known as the cornucopia of the real ruins!"

"Cornucopia, what do you mean by that?" Jiang Li blinked.

"In other cities, there are many rich people who will go to the martial arts arena, do you know why?" Li Nuonan's gaze moved to Jiang Li.

"Rich man, martial arts arena, are you going to see the excitement?" Jiang Li touched his chin and smiled.

"Hehe, there's nothing wrong with watching the excitement, but it's a bit Sven. Li Nuonan's eyes showed disdain, "Rich people, most of them pursue excitement, and the martial arts arena knows how to use the psychology of that kind of person, and every important battle will be opened to gamble, betting on who will win." Rich people throw a lot of mixed yuan coins into it, seeking passion! More of them are purely pursuing blood, depending on the fight to the death, and the more cruel those rich people are, the more excited they will be, and the more money they will throw! In the end, it is not the master of the martial arts arena who makes a lot of money!"

"Oh?" Jiang Li was even more interested, what did he come to the True Ruins for? First, he came to this place that was closest to the True Demon Battlefield and was inhabited, trying to explore more information about the True Demon Battlefield, and secondly, the need for training, a place like the martial arts arena could be said to be the most suitable for him. And now in order to dissolve the ghost weapon and slash the moon, he needs to comprehend the heart of martial arts, and this kind of place is also the best place to go, Jiang Li has the opportunity to say that he has to see everything.

Originally, Li Nuonan told Jiang Li about the martial arts arena, which meant to remind and warn him, because the money is not so easy to earn, the place in the martial arts arena is too cruel, and there are still few people who want to go there to make money or practice, not to mention the injured, there are countless deaths, that kind of ghost place, you can avoid it!

But as soon as he finished speaking, he saw Jiang Li's eager expression, he was really speechless, he dared to express his tone too inadequately, he didn't feel the warning meaning between his words? Forget it, anyway, he told him the truth, his life is his own, and whether he goes to the martial arts arena or not is his business.

Jiang Li didn't think too deeply about it for the time being, and had the opportunity to learn about it and then look at it. He said to Li Nuonan: "The information I told me today is good, you can go out to get some lunch now, and come back at noon." ”

Li Nuonan didn't even eat breakfast, why did he ask him to go to Zhang Luo for lunch, and he didn't have to come back until noon, isn't this a clear support for him? But Li Nuonan has nothing to say, who made Jiang Li his employer now, after answering Jiang Li, he closed the door and left the room.

Jiang Li bolted the door of the room, closed the door shut, and took out all the four-element black crystals he had from the night hat, a total of three. There are probably millions of mixed yuan coins here, which is not much money for the Yin family, it is estimated that this four-yuan black crystal is relatively small in circulation on the market, and it is not of great use to the Yin family, so there is only such a little inventory.

Jiang Li held one of them in his hand, sat down on the couch, and began to exercise.

When the immortal true qi was injected into the four-element black crystal, just like what Li Nuonan had done at the beginning, the black crystal emitted a four-colored light. Jiang Li began to try to use the True Qi to absorb the pure Heaven and Earth Essence Qi ingredients inside, this process was not difficult, and soon a stream of pure energy was introduced into the body along the True Qi, and was quickly absorbed by the flesh and body.

"This four-element black crystal, it's really easy to use!" Jiang Li just tried it a little, and realized its wonders, this kind of refining energy is much faster than simply refining external qi, and the cultivation speed will also increase several times.

"Okay, no problem with the first step, try that. However, this is not the focus of Jiang Li's upcoming experiment, he began to increase the amount of immortal true qi injected, due to the excessive external force of trying to refine the four-element black crystal, not only the heaven and earth essence qi components in the black crystal, but also the aura components, elemental body components, and alien energy components were all brought into Jiang Li's body.

Jiang Li didn't dare to go too far, he only brought in a small part of the four energies, and then stopped the injection of immortal true qi, and he was not sure if his idea could really be realized.

He began to constantly change the attributes of the internal qi in his body, from the true qi of martial cultivation, to the true yuan of Taoist cultivation, to the magic power of technical cultivation, and the alien energy of the cultivation of the supernatural, constantly trying to refine all the four-element black crystal energy brought in.

At first, Jiang Li was not used to it, but in the difficult exploration, because it involved the rapid switching of internal qi among the four attributes, Jiang Li was also doing it for the first time, so it was inevitable that it would be tricky.

However, due to Jiang Li's internal qi as he wanted, it didn't take too much time for him to slowly adapt to it, and the energy of the four-element black crystal did not appear to run wild in this internal qi transformation, and was slowly absorbed by Jiang Li's body, and finally completely eliminated.

"It's a success!" Jiang Li's eyes were excited.

"Since this four-element black crystal is naturally condensed by four pure external qi energies, ordinary cultivators can only absorb a quarter, that is really too wasteful, if the four energies can be used to the fullest, then it will be absolutely unbelievable, and the mixed yuan coins worth three or five hundred thousand are not a loss!" Jiang Li's heart was full of joy," My internal qi attribute is special, and I can transform among the attributes of the four cultivation systems, so I was wondering if I could directly absorb all the energy of this four-element black crystal, it seems that it works in theory, and I will try to gradually increase the absorbed energy to see if there is any problem!" )
