In the tin room, Zheng Jing was sitting at the table, concentrating on drawing a complex formation formation array on the table with white chalk.

Xuanqing just asked him to come back to prepare, and didn't say anything specific to prepare, so Zheng Jing naturally came to the aspect that he was most interested in.

Zheng Jing's biggest concern now is undoubtedly the level of alchemy, he is eager to rush up the proficiency of alchemy, the current alchemy has to be drawn into a formation before every time it is cast, and the reading time is simply a cheat, and it is something that you don't even think about relying on alchemy to fight.

On the table in front of him, in addition to the alchemy array being depicted, there is also a piece of graphite, which is Zheng Jing's whim, alchemy is the ability to understand, decompose, and reconstitute objects, scientifically speaking, it is to change the atomic structure of objects, in addition to being used for fighting, it can also accomplish many magical things.

Zheng Jing made the last strokes on the refining array, wiped the sweat from his forehead, and looked nervously at the piece of graphite placed in the center of the refining array. The main component of graphite is carbon, and at the same time, carbon is also the main component of diamonds, and theoretically, by changing the arrangement of carbon elements, cheap graphite can become expensive diamonds!

Of course, Zheng Jing is not short of money now, but even if he can accumulate the level of alchemy and make some extra money by the way, why not do it?

Alchemy unleashed! The refining array on the table erupted with a strong light, and the graphite dissolved little by little in the light of the refining array, turning into the most basic carbon element, and then reconstituted according to Zheng Jing's thoughts, Zheng Jing held his breath and waited for the final result.

Finally, after a violent flash of light, the light in the refining array disappeared along with the lines of the refining array on the table, and many carbon elements that had not had time to be rearranged together also dissipated, leaving behind a transparent object on the table that looked like a piece of glass slag and was difficult for people to notice without looking closely.

"That's it?" Zheng Jing couldn't even swing his fist to release his emotions now, and after his body was transformed, he didn't feel tired when he fought in the Thunder Dragon Gang's lair last night, but depicting this complex refining array made him collapse.

It seems that refining to the level of atomic structure is not something he can play with now, feeling that his efforts are not proportional to the reward, Zheng Jing was very depressed, and subconsciously touched the two sage stones in his pocket that were still glowing with a warm breath, according to the knowledge of alchemy in his memory, this is a magic weapon that can be refined at will regardless of the laws of alchemy, if you use this thing, even if you want to refine a fist-sized diamond, it should be easy, right?

After hesitating for a while, Zheng Jing still gave up the idea of using the Philosopher's Stone, the Philosopher's Stone made from the human soul as a raw material was too precious to be used casually. That's all it takes now, at least refining diamonds is by far the most effective way to increase your alchemy proficiency.

Picked up the piece on the table that was indistinguishable from the glass, found a piece of cloth and wrapped it, Zheng Jing smiled bitterly, no matter how small the mosquito is, it is still meat, find a place to see how much it can be sold.

called Guo Jia, I made an appointment yesterday to go out together today, but I was going out anyway, so I just called her to join her.

The two said that they met on a commercial street not far from Zheng Jing's warehouse, Zheng Jing deliberately changed into a decent set of clothes, washed his face carefully, and combed his hair before he went out, but he didn't expect that when he arrived, Guo Jia was already waiting at the agreed place.

"I really can't stand you idiot, I want to eat with you and come out to play together, you always push back, and it's hard to come out once and come so slowly, if you change to another girl, who will take care of you." Before Zheng Jing got closer, he saw Guo Jia pouting and complaining.

Zheng Jing scratched his head a little at a loss and said, "But, in terms of time, I'm not late, right?" ”

"Ah, I really don't know what to say." Guo Jia held his forehead with a defeated expression: "You made two more mistakes, first, if you are late than a girl on a date, you will be late!" Second, if a girl says you're wrong, you're wrong! Don't argue, the more you argue, the more wrong you are, you don't understand this bit of common sense, are you ready to masturbate for the rest of your life? ”

"This ...... This one...... Let's not discuss this anymore, shall we? Zheng Jing swooped for a long time, his face was red, and he didn't think of how to respond to Guo Jia's accusations, he used to be busy from morning to night for a living, how could he have the heart to study how to please girls?

"Poof—hey." Seeing Zheng Jing's embarrassment, Guo Jia couldn't hold back her laughter, she was wearing a cartoon T-shirt today, and the lower half of her body was a pair of denim shorts, showing her slender snow-white legs and slender figure to the extreme, this smile made her more lively, Zheng Jing's gaze couldn't help but stay on her smiling face for two more seconds.

"I'll forgive you this time, let's go." Guo Jia stepped forward as she spoke, and naturally grabbed Zheng Jing's arm and wanted to pull Zheng Jing, but Zheng Jing didn't move.

"What's wrong?" Guo Jia, who had already taken half a step, looked back at Zheng Jing suspiciously.

"Can you wait, do you know if there are any big jewelry stores nearby?"

As soon as she heard about the jewelry store, Guo Jia smiled again: "Oh? Enlightened, do you know that you bought a gift to please me? I'm not going to say no. ”

Zheng Jing didn't explain much, and was quickly taken by Guo Jia to a very large jewelry store on this commercial street, and as soon as he entered the door, a young female saleswoman greeted him.

"Hello sir, what is the need?" With a smile on her face, the saleswoman looked at Zheng Jing, and then looked at Guo Jia next to Zheng Jing, which was a customer with great purchase potential.

Zheng Jing glanced at the various dazzling diamond rings and jewelry on the counter next to the door, and asked, "Do you buy diamonds here?" ”

"Huh?" The saleswoman was stunned for a moment, the first time she met a man with a woman to a jewelry store who did not buy things but sold things, even if it was to sell things, she had seen people come here to sell gold, silver, and diamonds for the first time.

Guo Jia also looked at Zheng Jing in surprise, didn't this guy still pour the family bucket yesterday? Why did he run out to sell diamonds again the next day? This business span is too big, right?

"Come with me here."

The saleswoman took Zheng Jing to the counter specializing in diamond jewelry, and there was a man who looked a little older sitting behind the counter, and after the saleswoman explained Zheng Jing's intention, the man raised his head and looked at Zheng Jing in surprise, and said, "Take out your things for me to see first." ”

Zheng Jing didn't hesitate, and directly took out the transparent substance that had just been refined and put it on the counter. The man behind the counter put on a pair of glasses, leaned his head in front of the transparent substance, and after taking a closer look, his brow furrowed.

"Raw ore?" The man scratched his head, raised his head and glanced at Zheng Jing, who was dressed in ordinary clothes, with suspicious eyes, and doubted in his heart, this could not be stolen, but it was not right, country Z is not the main diamond mining country, even if you want to steal, it is difficult to find a place to steal.

In fact, Zheng Jing lacks some common sense in this regard, he simply wants to sell the diamond, but in fact, what he refines is not a diamond, but a diamond, the difference between the two is like furniture and wood, a piece of mined diamond must be cut, polished, and processed to be a fine diamond that can be sold and made into jewelry, and Zheng Jing's piece is just an unprocessed diamond.

"You wait here for a moment, I'll go upstairs and ask our manager." After the man dropped a sentence, he took the diamond brought by Zheng Jing and went upstairs.

While waiting, Zheng Jing took a closer look at the well-processed and cut real diamonds on the counter, and at this glance, he found that these diamonds that would reflect dazzling light under the light were no different from the one he had refined.

But this is all a trivial matter, Zheng Jing remembered the shape of these diamonds, and the next time he refines them, he can adjust them a little.

However, Zheng Jing didn't have to wait too long, and the man at the diamond counter came back soon.

"Your luck is good, we happen to have a master here who knows how to cut diamonds, the purity of your diamond is good, we are willing to spend 2,000 yuan to buy."

Although there was a big gap between 2,000 yuan and Zheng Jing's expected price, he didn't lack this money, so he didn't think much about it, so he sold the diamond at a price of 2,000 yuan. The salesman was secretly happy, the master who knew how to cut diamonds said that the impurity content of this diamond is almost none, it looks similar to synthetic diamond, but the hardness is by no means artificially made inferior products can be compared, although the volume is not large but the shape is very regular, as long as it is cut out completely, it can be sold for at least tens of thousands, and the commission in the middle is of course indispensable to him.

After selling the diamond, Zheng Jing also wanted to take Guo Jia to see the jewelry, but at this time, he suddenly heard a noise from upstairs, and asked the clerk suspiciously: "Is there something wrong with you here?" ”

"Don't you know? We're having a jewelry show here today, and it's upstairs. ”

"Can I go up and have a look, then?"

"Yes, but it's ......" The clerk saw that Zheng Jing and Guo Jia were dressed very ordinarily, and wanted to euphemistically say that they were all high-end products, not the place they should go, but when they turned their heads, they found that Zheng Jing had already taken Guo Jia's hand and walked up the stairs.
