In the Liuli Chamber of Commerce, a man in a wide black robe and a black cloak sat in front of the gorgeous jade counter, lightly tapped the jade counter, and said in an extremely hoarse old voice: "Help me exchange these first-level crystals, half into first-grade dark crystals, and half for second-level crystals." ”

"Oh, you're a crystallizer. ”

The young teller in green clothes turned his head a little excitedly, with sleepiness in his eyes, and first glanced at the old man in strange clothes, but he sneered in his heart, isn't he a crystallizer, in the Liuli Chamber of Commerce, the young teller thinks that he has seen more big scenes and big people, not to mention the crystallizer, even if he is a crystal array master, he has seen a lot.

I despise it in my heart, there are always some crystallizers who are pretentious, and pretend to be mysterious, and come to the Liuli Chamber of Commerce to hide their identities in black robes and black clothes, he has seen a lot of this kind of person, either to raise his own value, or to be a pure fool.

Crystalline is a unique name for the dark crystal that can be used by the source provider to directly absorb the source qi of the inner heaven and earth for cultivation after refining.

Crystallizer and Crystal Array Master are two professions with similar names, but their status is very different, because the Crystallizer is not talented enough, he cannot draw and outline the crystal array, he can only refine the dark crystal, so his status is undoubtedly much lower than that of the Crystal Array Master.

But despite this, the status of the crystallizer is still much higher than that of the ordinary source, so although the young male teller despises the surface in his heart, he does not dare to show it too much.

This old man in strange clothes was naturally Lei Yuan, who made Xiaoyu put on makeup and changed his appearance, and he didn't care about the young man's subconscious contempt, and took out all the first-level crystals in one go.

"This, so many first-level crystals!" The sleepiness in the young man's eyes dissipated at once, and he almost didn't scream out in shock, because what was placed in front of him was a full more than seven hundred first-level crystals!

With so many first-grade crystals, it would be difficult for even a high-grade first-grade crystallizer with rich refining experience to come up with them at once, because even the best first-grade crystallizer would need nearly a month of full-load refining to refine and accumulate seven hundred first-grade crystals!

With such a big stroke, could it be that this mysterious old guy is a second-grade crystallizer?! The young man guessed in his heart, his face couldn't help but become much more respectful, the first-grade crystallizer he could still despise it in his heart, but the second-grade crystallizer, he didn't dare to offend him no matter what.

"Wait, my lord, this is too much, small...... The little ones can't be the masters. With that, the young man immediately turned around and ran to the room inside, and after a while, a middle-aged man in a purple robe with a faint sense of nobility walked out.

The middle-aged man's eyes swept over the first-level crystals glowing with pure red light on the counter, and a gleam flashed in his eyes, and then stepped forward and said with a smile: "Hello distinguished guests, please forgive me for the inconsiderate hospitality, the contemptible person is the president of the branch of the Liuli Chamber of Commerce in Qinghe City, Gu Nan." ”

Lei Yuan under the black robe nodded silently, but he was a little surprised in his heart, how could he surprise the other president, well, it seems that he has to evaluate the influence of the crystal array master on the god of life.

Gu Nan picked up a piece of first-grade crystal, and said with a smile: "The distinguished guest took out seven hundred first-grade crystals at once, which is really a big deal, if the contemptible people are not mistaken, the refining and coloring of these first-grade crystals turned out to be flawless ten colors, and the first-level crystals of ten colors are rare in this Qinghe City." ”

The higher the purity of refining, that is, the higher the color, the more heaven and earth source qi retained by the crystal, and the more precious it is, and the ten color crystals show that the refining of the dark crystals is perfect.

"Xiao Zhou, immediately according to the request of the distinguished guest, these seven hundred first-grade crystals, half of which were exchanged for first-grade dark crystals, and half for second-grade crystals. Gu Nan's words changed and he commanded.

"Distinguished guest, the exchange of dark crystals for dark crystals of the same level is generally exchanged according to the refining fineness at a multiplier of 2-4, and your first-level chemical crystals are ten percentages, so they are naturally exchanged according to 4 times. Gu Nan looked at the old man in front of him with a smile and said respectfully:

"And the exchange of first-level crystals for second-level crystals is a ratio of one to ten, but there is really no ten-quality second-level crystals in the Chamber of Commerce, so let's do it, distinguished guest, I will exchange ten first-grade crystals for the ratio of one or two second-level crystals, you are satisfied?"

Hearing this, the young man who was about to go to the warehouse to exchange was shocked, this was the first time in all these years that he had exchanged chemical crystals and dark crystals according to the top exchange ratio.

"Yes, yes. Lei Yuan pretended to be calm, he is not a real crystal array master, although he roughly understands the exchange ratio of dark crystals and crystals, but the ghost knows that there are so many ways.

After a while, two jade boxes were placed in front of Lei Yuan, and Gu Nan smiled and said, "Distinguished guest, there are a total of 1,400 first-level dark crystals and 42 second-level chemical crystals, you can count them." ”

Saying that, Gu Nan took out a piece of warm lilac inscription jade and put it in front of Lei Yuan: "Hehe, distinguished guest, in a month, the Liuli Chamber of Commerce will hold an auction that will only be organized once every six months, this semi-annual auction is different from the usual auction, only the distinguished guests who have received the invitation of the purple inscription jade in Qinghe City can participate, and there may be something you need at the auction, if you are interested, you can come and have a look." ”

Lei Yuan glanced at it, reached out and picked up the lilac jade, and picked up the two jade boxes very rudely and left directly.

Seeing this, Gu Nan still chuckled and didn't have any dissatisfaction.

"President, I think he is a second-level crystallizer at most, is he worthy of your treatment?" said the young man Xiao Zhou suspiciously.

"Hehe, Xiao Zhou, your experience is still too shallow. Gu Nan smiled and shook his head, "Do you know what it means to be a first-grade crystal of ten colors?"

Xiao Zhou shook his head blankly, isn't it just that the old guy's refining experience is more sophisticated?

"No matter what grade of crystallization, if you want to refine it into a perfect ten colors, if you are just a crystallizer, no matter how high his grade is, it is impossible. ”

"This distinguished guest is at least a second-class ...... Crystal Array Master!" A faint shock flashed in Gu Nan's eyes.

"What?!" The young man's face turned pale, his body trembled slightly, and at the same time, he was afraid for a while, fortunately, fortunately, he had not offended the adult before.

......

Back at the residence, Lei Yuan immediately opened the two jade boxes, looking at the bright and clear dark crystals and chemical crystals inside, his mouth almost cracked with laughter.

"Ouch, I'm Cao, the crystal array master is really the most profitable industry in the world!"

Feeling that the source power in his body had almost only recovered three layers, Lei Yuan suppressed the urge to use the Phantom Cracking Purple Pole Array again to refine this thousand-four hundred first-level crystals.

He took out two second-level crystals with his backhand, and looking at the rich dark orange light shining on them, Lei Yuan frowned slightly, "Although this second-level crystals can be directly absorbed, there are obviously many impurities. ”

The purple mangs in his hand suddenly appeared, and in a moment, all the impurities of this second-grade crystal dissipated, and it became a ten-colored second-grade crystal.

If it was seen by other crystallizers who were desperately working and could only refine eighty percent color crystals at most, they would have created a ten-percent color second-grade crystal so easily, and it was estimated that they would vomit blood on the spot.

"Is there still half a month left? Lei Yuan's brows sank slightly, "Next, let's cultivate wholeheartedly." ”

Half a month later, I must get the opportunity to enjoy the moon with Lan Liluo, and I must figure out in front of her what is going on!

Lei Yuan never believed that there were too many coincidences in this world, and Lan Liluo and Han Xian'er, except for their different temperaments, their appearances were exactly the same.

Even if Xiaoyu confirmed that she was not Han Xian'er, Lei Yuan would not believe it, it was just a simple perfect coincidence!

When he heard about the banquet half a month later from Liu Xiaobai's mouth, this seemingly crazy thought popped up in Lei Yuan's mind, and since the thought was generated, it was destined to be impossible to disperse.

Because, it's about the girl he has been ashamed of all his life!

Converting the first-level crystals for cultivation was a plan he had made a long time ago, but the sudden change in the Phantom Cracking Purple Polar Array made him decide to directly exchange the second-level crystals.

The cultivation effect of the second-level crystal is not comparable to the first-level crystal.

Calming down, Lei Yuan meditated on the bed, closed his eyes, and the source power around his body began to run slowly, and soon after, the orange crystal in his hand trembled vaguely, and a wisp of pure heaven and earth source qi was stripped out, and it was slowly refined and absorbed by Lei Yuan.

Time passed so slowly.

In the following days, Lei Yuan practiced for eight hours a day, five of which were used to cultivate the source power, and the other three hours were used to cultivate the D-level source technique, the Splitting Stone Palm, which he had only just become a small success!

On the night of the fourteenth day, Lei Yuan, who was meditating on the bed and closing his eyes, suddenly opened his eyes.

"Is it finally time to break through?"

Lei Yuan, who had already consumed a full twenty pieces of second-level crystals, felt that the source power in his body seemed to be strong to a limit, and put away a piece of second-level crystals in his hand that had not been completely consumed, Lei Yuan gathered his mind and began to concentrate on feeling the thin primordial source qi between heaven and earth.

The source qi between heaven and earth is obviously many times thinner than the source qi in the crystal, but it is more natural and more suitable for the thunder source that is about to break through.

Wisps and wisps of heaven and earth source qi were gradually incorporated into the body by the thunder source, and after the source qi walked through the body source vein twice, it slowly merged into the dantian source force cyclone.

Suddenly, the source force cyclone in the Lei Yuan Dantian shrank slightly, and then suddenly enlarged, and after a moment of disorder, it slowly calmed down again.

"The apprenticeship level is complete, it's finally here!"

Lei Yuan opened his eyes, not too happy, looked at the night outside the window and the bright moon hanging in the sky, Lei Yuan got up, walked a long distance, and came to a bamboo forest.

This Split Stone Palm is worthy of being a D-level source technique, although relying on the Phantom Cracking Purple Pole Array to refine the Xuanyuan Primary-Order Source Core can be forcibly cultivated, but even if there is a cheat of the Source Technique Mirror Space, it is difficult to enter the realm again after Xiaocheng.

D-level source technique, it really deserves to be a source skill that can only be fully controlled by a general-level source.

Coming to the bamboo forest, tomorrow night will be the much-anticipated anniversary celebration dinner of the Outer Pavilion of the Deserted Pavilion, and the current disciples in the Pavilion are either cultivating frantically or are busy preparing, and no one should disturb them when they cultivate the source technique in this place.
