"Enough, enough!" said old Eugene, bouncing off the recliner like a ball, and pounced on the gold coin.

Wow, old Eugene took a handful, then let go, and couldn't help laughing as he watched the gold coin slip through his fingers and fall to the ground with a seductive sound.

"Go get the magic stone!" Downton walked to the counter.

This time, old Eugene did not slack off, as fast as a rabbit with an arrow, ran to the storeroom, and took out a suitcase.

Lifting the lid, inside is a small grid like a chessboard, and magic stones cut into fist-sized shapes are neatly placed.

"It's all high-grade magic stones, one hundred kindlands per gram. "Old Eugene has made an offer, ready to slaughter this hillbilly severely.

According to the magic energy contained in each gram, the magic stone is divided into lower grade, middle grade, upper grade, excellent grade, and excellent grade, and the corresponding price is also different.

A top-grade magic stone is already more valuable than gold of the same weight.

"Top-grade, don't you say it, take the litmus reagent to test!" Downton picked up a magic stone and observed, the cutting surface was smooth and well handled, but it didn't mean that its content was high.

"Haha, I don't have litmus here. Old Eugene had a smile on his face, but he was chuckling in his heart, and secretly said that it was terrible, and he met someone who knew how to do it.

Litmus is a blue pigment extracted from lichen plants that live in dark and humid environments, and its properties are blue powder, which is a commonly used indicator of magic energy concentration.

After dissolving in water at room temperature, when it comes into contact with the magic stone, it will be stimulated by the magic energy to cause the conjugate structure to change, resulting in a discoloration reaction, from light to dark red, the higher the concentration of magic energy, the darker the color.

There are ten color ranges listed on the litmus color card, and by comparing them, you can accurately distinguish the quality of the magic stone.

Downton has a younger sister who went to school at St. George's School of Magic, and she has helped her buy magic stones, and she has experience, and even if she doesn't understand it, there is still a magic book, and she will definitely not suffer a loss.

"You can go and buy it, it's definitely in the grocery store in Old Grande. "Downton didn't bother to debunk old Eugene, litmus is the basic medicine of potions, and any apothecary can find a box.

"By the way, I remembered, and there was a bottle. Seeing that he couldn't blind Downton, old Eugene was reluctant to spend money, and took out a thumb-length and coin-thick dark brown bottle from the counter.

"If you don't, I'll come!" Downton looked old Eugene in the eye and placed the magic stone in front of him.

Old Eugene couldn't help it, so he pinched the rubber dropper, sucked some litmus liquid, and dripped it onto the magic stone.

The original purple liquid immediately faded and faded.

"Look, such a dark color is definitely the best grade, that's right, you will be charged a hundred gold coins per gram, and it will be cheap for you. "Old Eugene chattered a lot, just didn't take a color card to compare colors.

"Your Potions Master qualification is fake, isn't it? Even if I don't look at the color card, I know that it's just a medium-grade magic stone, old Eugene, how many people have you pitted?"

Listening to the faint mockery in Downton's tone, Old Eugene's face couldn't hold back, and he was a little embarrassed, as a half-potions master, his vision and experience were still a little, and he knew that what this kid said was right.

"A hillbilly actually knows the litmus reagent, and he can distinguish the grade of the magic stone without looking at the color card, is there any heavenly reason?" Old Eugene slandered, agreeing with Downton's answer, "Seventy gold coins, no less." ”

"Ten gold coins at market price, you dare to multiply them, keep them moldy!" Downton turned and left, he had had enough of this guy.

"Wait, well, fifty gold coins, no less. ”

Old Eugene hurriedly ran a few steps to La Downton, although Morning Mist Town is the largest town on the border, but less than the peak season of the year, the caravans do not come, and his apothecary store has almost no business, after all, the town is full of bitter Haha civilians, and there are few demons.

"Seven!" Downton continued to haggle.

"You're asking for my life, this price, minus transportation costs, storage fees, is not profitable at all. Old Eugene spat and recounted the difficulty of life.

"One price, seven folds, seven gold coins per gram, this quality of magic stones, I want as many as I want. Downton shook the gem in his hand.

"Seven percent off is too little, what? all of them? You wait!" Old Eugene immediately wrenched his fingers, calculating how much he could make from this transaction.

Downton knows the character of old Eugene, this guy is greedy, but he has no corresponding business talent, and when he sees a little benefit, he wants to grasp it in his hands, which is much worse than old Grande.

"Seven folds is too little, can you add a little more?" Old Eugene begged, but he didn't know that this attitude had already exposed his idea of agreeing to the deal.

"I changed my mind, six folds, do you like to sell or not, I'll go to old Grande, except that there is no medicine, his goods are more complete. Downton lowered the price again, and he suddenly remembered that there was so much dust piled up on the box, which means that it has not been touched for a long time, and it is obviously impossible to sell.

Old Eugene hesitated, and sold it at a six-fold discount, which was already lower than the original purchase price, but he kept it, so he could only press the bottom of the box, and look at the market price of the medium-grade magic stone, ten gold coins per gram.

This means that a pound of magic stones, worth 5,000 gold coins, ordinary magic people can afford to consume, they often use low-grade magic stones, just in battle, they have to use it before they are willing to absorb magic energy.

The main customers of the pharmacy are the mercenary groups that escort the caravan, and some of them will have enough magic stones, and they will definitely not let the black-hearted merchants make more money.

In battle, there are drawbacks to absorbing magic stones, which are far less time-saving and labor-saving than directly drinking magic energy potions, so magic stones are more used in the magic industry such as forging, magic potions, and alchemy.

Demonic beings are generally willing to absorb magic stones when they hit the ranks, and they are not willing to use them in their usual cultivation.

Seeing that Downton was about to walk out of the store, old Eugene compromised, after all, such a rich customer could not meet one for several years.

"Don't go, I'm selling!"

Once the decision was made, Old Eugene moved quickly, and it took ten minutes to count the gold coins, estimate the gems, and complete the transaction.

This is a small profit from Downton, but he can't be happy when he looks at the twenty catties of medium-grade magic stones, which are actually worth 60,000 gold coins.

If a magician wants to improve his strength quickly, he needs to absorb a large amount of magic energy, and relying on the free magic energy in the space alone is far from enough, he has to use magic stones and potions to make up for it, which means money.

"It's no wonder that the Robinson trio will be happy when they first discover that the dungeon's magic energy concentration is five times higher, no wonder as long as they find a region with a high magic energy concentration and report it to the country, they can get a hereditary earl title at the very least. ”

Downton sighed with emotion, only after becoming a demonic can he intuitively understand the importance of magical energy, no matter what plane it is, they are the most strategically valuable resources.

If you want to become a strong person, you don't have resources, maybe it's possible, but it's too much of a waste of time, how many decades can you waste in a person's life?

"Elaine, brother is sorry for you!" Downton sighed, he thought of that talented sister, if he could provide her with enough resources, I am afraid that she would have been promoted to the war rank, right?

Downton clenched his fists, he must improve his strength as soon as possible, kill the three Robinsons, and delay for one more day, so that they can absorb one more magical energy.

"Where did you get your money?" said old Eugene, blinking two big eyeballs, full of curiosity.

"Bought it for someone else. Downton said casually, he used to think that his money bag was full enough and he was a rich man, but now it seems that he is still a poor ghost.

"I'll just say, how can you have so much money?" Old Eugene scratched his belly, rolled his eyes, and smiled, "Do you want to buy some stone skin potions to defend yourself?" Take so many magic stones out of the house, be careful of being robbed." ”

"Take a bottle and see!"

This time, Old Eugene was no longer afraid that Downton would break the potion, so he picked out more than a dozen potions and put them on the counter.

"Liliang potion, agility potion, can double your liliang and agility in ten minutes, only fifty gold coins!"

"I don't want these, is there a potion to replenish magical energy?" Downton picked up a bottle of potion and saw that it was labeled with Swift Shadow, which was a potion that increased speed for a short time, and it was good for escaping.

"Quick-acting magic energy potion, only one bottle is needed, and it can replenish all the magic energy of a soul second-order. Old Eugene patted his chest and proudly sold, "This is a potion made by the Royal Potions Master himself." ”

It is a two-inch long test tube with a rubber stopper on the top of the bottle.

It contained a pale pink liquid, and Downton shook it and saw a lot of particles.

"You can see the quality of good or bad, that's what you call seeing the undead, if I don't pit you this time, I will be restless when I sleep." Old Eugene spat on the benefits of the potion, blowing the sky.

Downton didn't understand, but he knew that with Old Eugene's character, he would definitely not take any good goods, and nine times out of ten he would pit himself.

"For the sake of the large number of magic stones you bought, one hundred gold coins, you take this bottle of speed magic potion. "Old Eugene put on a 'you've earned' look on his clothes and tried his best to sell them.

"What do you think?" Downton took a few steps back, took out the tome, opened it, and wrote a question.

The Grimoire unleashed Soul Detection, and a green light swept over the potions on the counter.

"You're a magician?" said old Eugene.

"A bottle of discarded potion that should be destroyed, after drinking, it will replenish some magical energy, but the side effects are greater!" Homer said on the page.

"What about the other potions?"

"It's all discarded medicines, is this a garbage disposal plant? According to the Pharmacy Law, no pharmacy is allowed to buy or sell discarded, expired medicines. Homer was quickly relieved, how could the Potions Guild have time to take care of this kind of border town?

"No, I can't afford it. Downton put down the potion, took his suitcase, and turned to leave.

"Eh, don't go, count you cheaper, seventy, no, fifty gold coins. Old Eugene shouted at the top of his voice to chase Downton, "Twenty is all right?"

"Keep it for yourself!" Downton shook off old Eugene's hand
