In the middle of the night, when Chen Xiaodong woke up, Chen Xiaodong looked at the clock, it was three o'clock in the morning, Chen Yun and Blue did not return to the dormitory at night, the dormitory was empty only Chen Xiaodong, Chen Xiaodong took a shower, changed his clothes, left the dormitory, and went to the alchemist research institute of the school, he wanted to borrow the equipment of the alchemist research institute.

The Alchemist Institute of the Mar Academy was not famous in the Arad continent until one person came to the Alchemist Institute of the Mar Academy, and that was Norton.

Norton proposed the idea of striving for innovation, as well as new alchemy methods, and Norton's efforts made the Alchemists' Guild officially recognize that if Norton wanted to join the Alchemists' Guild, then there would be a place for him, but Norton refused, preferring to be the director of a research institute at Maar College than to go to the Alchemists' Guild.

Chen Xiaodong sneaked all the way to the research institute, this time he planned to refine the dark series of potions, if it was discovered, then things would not be so simple, not to mention that the identity of the alchemist was one of Chen Xiaodong's hole cards.

Chen Xiaodong paid a hundred credits to enter a laboratory, which made Chen Xiaodong a little painful, don't look at the credits of the research institute to ask for so much, in fact, it is not much, the equipment of the Alchemist Research Institute of Mar Academy is no worse than that of the Alchemist Guild.

Chen Xiaodong checked whether the door was completely locked, and then took out a bunch of dark series materials and put them on the table, ready to start refining the lowest level of dark elixir, Dark Water.

Dark water is tantamount to poison for ordinary people, but it is undoubtedly a good thing for magicians, magicians often use dark water to summon some special monsters, and use dark water as an intermediary to make contracts, and later found that most of the magicians who have used dark water for a long time will have a great change in temperament, although this potion is not very harmful, all the empires on the Arad continent directly banned this potion, but there will still be people secretly refining it in private.

The refining power of the dark water is not very high, and there are fewer and fewer alchemists refining the dark water potion, after all, the reputation of refining this forbidden medicine will always be not good, which has caused the price of the dark potion to soar a lot recently.

Three hours later, Chen Xiaodong, who had lost three dark crystals, successfully refined a bottle of dark water, looking at the dark crystal left on the table, Chen Xiaodong wiped the sweat on his forehead and breathed a sigh of relief, if there was no dark crystal in failure this time, while the feeling was still there, Chen Xiaodong invested the fifth dark crystal in a while, and in the end he was not disappointed, five crystals produced two bottles of dark water, this harvest made Chen Xiaodong a little surprised.

Looking at the two bottles of dark water in his hand, Chen Xiaodong took out a bottle of fanatic potion, hesitated for a while, and finally seemed to have made up his mind, mixing the fanatic elixir with the dark water, the moment the two elixirs touched, they reacted violently, like boiling water, and after a while, a dark red elixir was produced.

Chen Xiaodong picked up this strange potion, frowned, took it to the detection instrument next to it, and dropped two drops of the elixir on the instrument, and the instrument showed an unknown elixir, the effect was the same as the evil elixir, but the effect was smaller than the evil elixir, specifically the low-level evil elixir.

Chen Xiaodong also had a flash of inspiration, only then did he think of what the result would be when the two drugs were mixed, Chen Xiaodong deleted the analysis records of the instrument, cleaned up the dark materials in the laboratory, and opened the vent, because the lease of the laboratory was one day, which was enough for the dark aura of the laboratory to dissipate.

After Chen Xiaodong left the laboratory, a figure appeared in Chen Xiaodong's laboratory, rummaging next to the instrument, and then the instrument appeared with the analysis data just now, and the figure sighed: "The combination of medicine and medicine? The power of science, it's great! ”

……

Chen Xiaodong left Mar Academy, it was seven o'clock in the morning, Chen Xiaodong had a meal in the school cafeteria, and then went to the black market to sell his potion, on the way Chen Xiaodong met the stall owner who sold him dark crystals, and the stall owner's stall also had five dark crystals on it.

"I want these dark crystals." Chen Xiaodong stood in front of the stall owner and pointed to the five dark crystals and said.

"Is that you?" The stall owner reacted, the person in front of him had just bought his own dark crystals a few days ago, which alleviated his urgent need, and then the stall owner added: "These crystals are the same price as last time." ”

"Deal." Chen Xiaodong said indifferently, as if he didn't want to have more to do with the stall owner, the stall owner also took out the badge in surprise, and after the transaction between the two was completed, Chen Xiaodong added: "If you have dark crystals, you can keep them and sell them to me." ”

After Chen Xiaodong finished speaking, he left the stall, and the stall owner looked at the back of Chen Xiaodong leaving, thoughtfully, what does this person need so many dark crystals for? The stall owner was also confused, so he simply didn't think about it so much, and after selling the dark crystal, the stall owner cleaned up the stall and left.

Chen Xiaodong found the medicine ghost after wandering around for a while, the medicine ghost was lying on the stall sleeping, Chen Xiaodong walked to the medicine ghost's stall, took out the dark water and put it on the table in front of the medicine ghost, and said to the medicine ghost: "How much can it be worth?" ”

The medicine ghost got up from the stall, opened the lid and smelled it, dipped a little bit of dark water and tasted it, and said in amazement: "This dark water is in good condition, and I can give you 1,000 gold coins." ”

Chen Xiaodong didn't respond to the medicine ghost, and seemed to acquiesce to the price, then took out the bottle of the mixed potion of fanaticism and dark water, and said, "What about this bottle?" ”

The medicine ghost was a little surprised, it was the first time he saw this dark red potion, he took it from Chen Xiaodong's hand, and looked around suspiciously, he had never seen this potion, he opened the stopper of the potion, and then took out the instrument, the instrument said that there was no such content, the medicine ghost dipped a little medicine and tasted it, the medicine ghost was very surprised, and the medicine ghost fell into silence.

"It's a new potion, isn't it?" The medicine ghost asked suddenly.

"Hmm." Chen Xiaodong responded.

"I don't want to price this potion, so let's do it, you don't sell this potion to anyone except me, I'll go find the one above me... Ahem..."The medicine ghost stopped talking, coughed twice, as if he had just said more, and added: "I'll go to my friend above and ask about the value of this potion, this is a 10,000 gold coin card, you take it first." ”

The medicine ghost took out two cards, a gold coin card with a denomination of 1,000, and a golden card with a denomination of 10,000, this kind of gold card can be taken out in the money village of the Arad continent, Chen Xiaodong took the two gold coin cards and said to the medicine ghost: "Yes." ”

Then Chen Xiaodong left the medicine ghost's stall and went to other places to buy alchemy materials, which was also Chen Xiaodong's 'second pot of gold'.

After the medicine ghost cleaned up the stall, he quickly left the black market, the medicine ghost went to a tavern in Huttonmar, there was only one bartender in the tavern, and there were no other customers, the medicine ghost walked to the bar and sat down, and gently took out a sign from his arms, the bartender handed over a glass of wine, and secretly scanned the medicine ghost's brand, the bartender nodded, and the medicine ghost left the bar after drinking, and walked to the door of the toilet, the medicine ghost put on another mask, pushed open the secret door of the toilet and walked in.

Inside the secret door is a secret passage, and soon the medicine ghost walked out of the secret passage and came to a secret room, there are more than a dozen in the secret room, wearing masks like medicine ghosts, holding a brand like the medicine ghost, but the numbers on it are different, and everyone saw that the medicine ghosts not only snorted coldly.

The medicine ghost didn't pay attention to these people, pushed open a door in the secret room, walked in, there was a tall figure inside, saw someone pushing the door open, a little annoyed, saw that it was a medicine ghost, the tall figure gave up the idea of reprimanding, the tall figure said to the medicine ghost: "No. 21, why did you leave the black market?" What's the urgency? ”

"Godfather, someone has sold a new type of dark potion on the black market, which is a low-grade evil potion, I have come to ask if this potion can be monopolized?" The medicine ghost took out Chen Xiaodong's bottle of potion and offered it with both hands.

"Oh? I'll give it a try. The man who was called the godfather by the medicine ghost took the potion, observed it, and then tasted the potion, it seemed that he didn't feel like it was enjoyable, and drank the whole bottle, and the godfather was full, and the godfather's eyes lit up, and he said to the medicine ghost: "This thing is good!" It's probably a third-level potion, and on the 21st, you've done a great job. ”

"Don't dare, it's the godfather's credit!" The medicine ghost was terrified.

"What I say is yours is yours." The godfather gave him a meaningful look.

"I'm willing to go to the soup for my godfather!" The medicine ghost seemed to have figured out the godfather's unexpected words, and knelt down directly to take an oath.

"Do your own job, I will receive as much as I want from this potion in the future, minimize the outflow, and purchase the price of 3,000 a bottle." The godfather gave the order to the medicine ghost, and seemed to be satisfied with the medicine ghost's attitude, and then added, "That alchemist has a good time to woo you." ”

"I just gave him 10,000 gold coins and told him not to sell potions." The medicine ghost responded.

"Keep an eye on that alchemist." The godfather nodded, the 21st was very clever, and waved his hand, signaling that the medicine ghost was leaving, and the medicine ghost bowed, and then left the tavern.
