()ps: Thanks to "Yuemeng Ruihui" for the valuable monthly ticket, and thanks to "nykfany" for the tip.

"What do you want to buy, sir?" The middle-aged man walked up to Ito Cheng slowly, put his hands in the pockets of the white coat he was wearing, and asked Ito Cheng with a smile on his face.

"These are all alchemy potions?" Itocheng turned his head and looked around, looking at the red or blue, green or purple potions in the glass cabinets standing in front of the walls on both sides, which were about the size of a thin chemical test tube. asked the little bottle.

"Yes." From Ito Cheng's words, it was seen that Ito Cheng was the first time the middle-aged man entered this kind of shop and nodded.Then, without Ito Cheng asking, he took the initiative to introduce, "Those red ones are therapeutic medicines, which can heal wounds when applied externally or internally. Those blue ones are spiritual medicines, which can stimulate the brain to forcibly produce mental power when taken internally. Those green ones The purple ones are body strengthening potions, which can increase the user's strength to a certain extent. The purple ones are specialization potions, which can temporarily increase a person's concentration level, and can be used to complete spellcasting and scientific research..."

"Of course, if you don't need these things, you can also buy these things. For example, the pink one is a scar remover. After applying it, any scars can completely disappear within three to four days. And this ink Se whitening potion, yellow se odor-removing potion, blue slimming potion, etc..." Then the middle-aged man pointed to something in another window and introduced.

"This group of alchemists are really good enough to keep pace with the times, and they even understand that women are easy to make money." Ito Cheng, who was listening to the middle-aged man's introduction, secretly said speechlessly.

"How do you sell your potions?" Ito Cheng asked after the middle-aged man finished his introduction.

"What kind of potion are you asking about?" The middle-aged man turned his head to look at Ito Cheng again and asked.

"For example, that healing potion." Ito Cheng asked with his eyes on the bottle of bright red potion.

"That depends on the purchase method you choose." The middle-aged man who also focused on the healing potion said, "There are generally three transaction methods in alchemy shops like ours. One is ordinary money and goods transactions. The most simple and clear, as long as you pay the corresponding amount, the medicine is yours."

"One is a barter transaction. For example, you take out some things that you don't need, but I may need, and exchange them according to a certain value ratio. This kind of transaction method is generally more suitable for mercenaries or bounty hunters. "

"The last one is to solve the transaction." When talking about the last one, the middle-aged man paused, and then continued, "If you have no money and no items that I think can be exchanged, but you think you have enough Knowledge. It can be used in this way.”

"Can you elaborate on the third way?".Ito Cheng, who still doesn't understand the third method, looked at the middle-aged man and asked.

"Okay." The middle-aged man nodded first in response.Then he continued, "Since my brother can find this place, he should know about the existence of people like us alchemists, and when we study alchemy, we often encounter various problems. Some of us can do it day after day. The answer was obtained in the experiment of ri. Some of them are still inexplicable. And the third trading method is produced in response to this reason."

"As long as you can answer the puzzle I left, then according to the value of that puzzle in my heart, you can exchange it for a corresponding amount of alchemy potions!"

"It's a great way to trade." Ito Cheng, who figured out the third way to trade, sighed softly.

"Yeah." The middle-aged man also agreed with emotion.

"Now. Customer, which transaction method do you choose?" Then the middle-aged man calmed down and asked again, returning to the topic.

"Tell me about the first two first." Ito Cheng tilted his head and thought for a while before deciding.

"Yes." The middle-aged man agreed, and then introduced, "If the first transaction method is used, then the price of the light healing potion is [-] dollars a piece."

"Hiss..." Ito Cheng, who was completely shocked by the value of the potion, took a light breath subconsciously.

"If you follow the second method, you only need to take out one moon firefly, and you can replace it with three light healing potions, or one primary healing potion." Wei Wei, a middle-aged man who saw Ito Cheng's performance in his eyes Smiling, he continued without a pause.

"Moon firefly...you mean the kind of moon firefly that only grows in the grand canyon that is more than [-] meters deep and has an underground river flowing through the bottom?" Ito Cheng tilted his head and asked the middle-aged man beside him. .

"It seems that the guests know these things very well." The middle-aged man looked at Ito Cheng with some surprise and said.

"Forget it, I haven't been to any deep mountains and old forests recently, so I still use money to buy them." Ito Cheng ignored the surprise of the middle-aged man and shook his head slightly.

"Then what kind of medicine is the customer going to buy?" The middle-aged man was just surprised, and didn't think that Ito Cheng knew how strange the moon firefly grass was, so he returned to the topic after hearing the words and asked.

"Light, primary, intermediate, and advanced healing potions and mental recovery potions, monograph potions, memory potions, and body strengthening potions, three each." After carefully browsing the potions in the window, Itocheng said.

"Okay." The middle-aged man nodded, turned around and went back behind the counter, leaned over to open the alloy safe below, extracted the medicine Itocheng needed from it, and put it in a small freezer. He re-locked the safe for the first time, and stood up holding the small freezer.

"Customer, the total is 110 U.S. dollars." The middle-aged man put his hands lightly on the small freezer and said, looking at Ito Cheng who walked to the counter.

Although he had estimated the value of these medicines, Ito Cheng, who still didn't expect to break one million, twitched his mouth, then took out an International UnionPay bank card and handed it to the middle-aged man.

"By the way, are there any precautions or contraindications for using these medicines?".Ito Cheng asked the middle-aged man who took the bank card and worked on the credit card machine.

"Yes." The middle-aged man explained while operating, "First of all, these medicines must be stored at a temperature below five degrees Celsius. Otherwise, they will slowly lose their efficacy at room temperature."

"Secondly, after opening the medicine package, use it within 3 minutes, otherwise the energy of the medicine will evaporate and disappear in the natural air, not only will it no longer have the original effect, but it may also produce toxicity."

"Please write down the words." At this time, the middle-aged man handed the bank card and credit card back to Ito Cheng and said, and then continued as Ito Cheng signed with a pen, "Finally, the effects of these medicines are all caused by the strong effects on the human body." Stimulation, so after use, it will produce different side effects according to individual differences of each person."

"For example?" Ito Cheng asked after handing back the signed credit card slip to the middle-aged man.

"Take therapeutic medicine as an example. Because the healing effect is achieved by stimulating the body's self-healing ability. Therefore, after the medicine is effective, the human body will experience high fever, high energy consumption, strong hunger or ischemic dizziness reaction, etc." The middle-aged man who swiped the card and put it away said, "So if you want to use healing potions, it is recommended to use them in a safe place after the battle."

"Uh...then trouble you to tell me something else." Ito Cheng continued to ask with a look of astonishment when he found that these alchemy potions did not seem to be as good as he imagined.

"Okay." The middle-aged man agreed.Then Ito Cheng explained the possible sequelae after using the medicine he bought.

"It seems that when giving the medicine to Emma and the others for research, it is necessary to remind them to find a way to deal with these sequelae." After listening to the middle-aged man's story, Ito Chengxin said.

"Thank you boss. I'm leaving." Then Cheng Ito lifted the small freezer and smiled at the boss.

"Go slowly, don't send it off." The middle-aged man looked at Ito Cheng and said.

Itou Cheng nodded.Carrying the small freezer, he turned around and walked out of the Martin Pharmacy, and continued to wander around in other shops.

And after visiting two alchemy pharmacies and buying alchemy potions such as Sensitive Potion, Perception Potion, and Agility Potion that were not available in Martin Pharmacy, Ito Cheng walked slowly to a weapon shop.

"Iron Metal Weapons Shop." Ito Cheng read softly while looking at the store sign.Immediately without hesitation, he stepped into the equipment store.

This equipment store may be famous, or for some people, equipment is more popular than medicine, so it is not like the previous few medicine stores. There is no one else in the store except the boss, but there is a man and a woman. Two guests are present.

Ito Cheng, who saw the boss greeting the guests, didn't bother, and browsed the weapons on the shelves on both sides.

"It's fucking expensive." After browsing a few weapons, Ito Cheng, who looked at the price written under the weapon, couldn't help but cursed inwardly.

But it's no wonder Ito Cheng wants to curse people, just the dagger that Ito Cheng is looking at now, which is no different from ordinary daggers, costs more than 8 US dollars, or nearly 50 RMB!It is enough to buy a house in a second-tier city.

"Guest, are you satisfied with this weapon?".Just when Ito Cheng was speechless about the price of the dagger, a male voice suddenly rang in his ear.

Ito Cheng looked in the direction of the sound, and then a middle-aged man who was about 1.9 meters tall, burly, square face, with short blond hair, looked about forty, and was about to walk up to him came into view into Ito Cheng's eyes.

"Can you tell me about the characteristics of this dagger." Ito Cheng nodded to the middle-aged man, pointing to the dagger in front of him and said.

"Of course." The middle-aged man smiled heartily, then reached out to take the dagger on the shelf, and while showing it to Cheng Cheng, he introduced, "This dagger is a special alloy made by alchemy, with a special flame. The dagger made by the forging method is characterized by its exceptional sharpness, it can easily cut through a ten-centimeter-thick alloy steel plate without any fracture, and it does not have the reflective properties of metal."

When it comes to the lack of reflective properties, the middle-aged man blocked the light in the store with his body, and danced the dagger in his hand twice in the shadow formed by his body as a demonstration.

"Are there no other features besides this?".Ito Cheng shook his head slightly and asked.

"The specificity of this dagger is the pursuit of sharpness. If you want to have unique attributes, maybe the dagger over there can meet your needs." The middle-aged man shook his head, put the dagger back on the shelf, and pointed Said another dagger not far away.

"Oh?" Following the middle-aged man's fingers, Ito Cheng also saw the dark dagger.

"This dagger is still forged using a special alloy produced by alchemy and a special flame in a special way, but it is different from the previous dagger. The metal used in this dagger is not very sharp, but it has super high The amount of energy conduction can strengthen and condense the power used to strengthen the attack power." The middle-aged man who brought Ito Cheng to the dagger reached out and took the dagger and handed it to Ito Cheng.

Ito Cheng was not polite when he heard the words, and mobilized a little energy to run on the dagger in his hand.In an instant, there was only a soft sound of "exposure", and a silver-white light of the air blade immediately protruded from the dagger, exuding a sharp and extremely cold feeling.

Along with the sound of the dagger, a man and a woman who were choosing weapons by themselves also subconsciously set their eyes on Ito Cheng and the dagger in his hand.

"And not only that, this dagger has an inlay on purpose, and some strange energy crystals can be installed to add additional attributes to the dagger." The middle-aged man who was satisfied with the effect of the dagger said proudly.

"Strange crystal?" Ito Cheng, who grasped a certain word in the middle-aged man's words, said in his heart calmly, "It's probably the crystal on the broken alchemy stick."

"Boss, do you have strange crystals for sale here?".After dissipating the energy and returning the dagger to the boss, Ito Cheng asked tentatively.

"There are so many, but they are not as rich as crystal specialty stores." The middle-aged man said with a slightly embarrassed face when he heard the words.

"May I take a look at it?".Ito Cheng asked curiously.

"Okay, please come with me." The middle-aged man nodded and said, then walked back to the counter with Ito Cheng, shortly took out four or five specially packaged boxes from the drawer under the counter and put them on the counter table superior.

"Guests, please take a look." The middle-aged man placed the boxes in a straight line in front of him, and introduced them one by one, "This red one is an energy crystal of the fire attribute, this blue one is a water attribute crystal, and this white one It is of the ice attribute, this golden one is of the sharpness attribute, and this blue one is of the wind attribute..."

"How do you sell this kind of crystal? I mean according to the money-goods transaction model." Ito Cheng picked up the white crystal that was almost exactly the same as the crystal inlaid on the scrapped alchemy stick in his hand and asked.

"58 dollars each." The middle-aged man said very simply.

"..." Ito Cheng, with a slight twitch at the corner of his mouth, put the crystal in his hand back on the table, and said in his heart, "Go to the office above and ask how much the special crystal manufacturing formula costs to buy. This thing is really expensive. It’s too profitable.” (To be continued. Mobile phone users, please go to read.)
