Tro Leader Beak Town, not long ago officially changed its name to 'Tro Magic Academy Attached Middle School' - in a large classroom in the middle school of the original Birdbeak Town Lord's Academy, an experimental class of chemistry and magic is being carried out.

The teacher on stage is called Mr. Link. If you only look at the face, the dull skin is full of wrinkles, and the sparse gray hair that cannot be distinguished from its true color is even more old, and half of the body is buried in the loess. However, his real age is only in his fifties, and his voice is full of energy, as evidenced by his relatively strong body and the normal skin exposed outside the half-amputated sleeve below his neck.

Rumors among students say that Mr. Link had his face disfigured when he was young due to a failed magic experiment, and that he had barely recovered to this state after treatment. Another theory is that he drank homemade magic potions all year round. But no matter what, there is no delay in giving nicknames such as 'Old Monster', 'Old Fire Demon', and 'Chemical Maniac' on his head, and it seems that giving teachers a terrible nickname is a common way for students to relieve stress in the face of study pressure.

However, Mr. Lin Ke doesn't seem to care about this, but is a little complacent about this nickname, even if he leaks his mouth in person, it is just a verbal reprimand, and there is no further punishment. You must know that in the school rules, the lightest insult to the teacher is to run five laps of the playground, and the heaviest punishment is to withdraw from school.

"The specific principle of this metal displacement experiment has already been explained in class, so I will not repeat it. However, another point needs to be reminded that all the consequences of not following the experimental procedures are your own responsibility. For example, Luckfield, who burned his hair by the alcohol lamp last time, and Piris, who burned his sleeves last time......"

At this point, the experimental classroom suddenly burst into laughter. Mr. Lin Ke was not annoyed, only tapped the table to signal quiet, and then asked the squad leader indifferently, "What's the matter?"

The class leader blushed and stifled a smile and explained, "It was Pitipis who burned his sleeves, and Piris means horse manure in lingua franca. ”

"Oh, it's my accent problem, I ask this leather ...... Well...... The classmate who burned his sleeve apologized. Mr. Lin Ke also smiled and waved his hand to apologize. Because the townspeople of Birdbeak come from all over the United Kingdom, the accent issue has caused many jokes and misunderstandings in various walks of life, and most of the townspeople have become accustomed to it and expressed understanding, and only the school students will enjoy it. However, due to the peculiar appearance of Mr. Link, the smile frightened the students, and the remaining laughter quickly disappeared.

After a small episode, Mr. Lin Ke took out a glass test tube and a thin iron bar, and continued: "The reason why I remind you again is because the experimental equipment this time is different from the last few times. This highly transparent special glass test tube five copper coins, this iron bar one copper coin, if damaged or lost, according to the price. I think your parents will be willing to teach you a lesson when they see this kind of bill. ”

The students are no strangers to this kind of fine mechanism, but they are secretly careful and pay attention to the experimental equipment in front of them.

Link nodded with satisfaction at the students' reactions, and said, "But I'm also personally offering a small reward to those lucky ones who have the same talent for fire magic as me. As he spoke, he posted a piece of paper on the blackboard behind him, which was painted with five gradient color blocks from blue to green, "When iron reacts with copper sulfate solution, the color of the liquid in the test tube will change from blue to green, and whoever can use the fire magic medium to hinder or reverse this reaction process can get the corresponding reward if the color of the solution stays at the stage shown in the diagram at the end of the class." ”

The students whispered about the specific rewards on the blackboard, from the most basic 'one time late to be penalized' to the highest level of 'one copper coin' or 'final chemistry plus five points', and each reward was heartwarming in every sense of the word. Then several students with a talent for fire magic quickly became the focus of attention, asking if they could help their brothers.

Seeing that the classroom was about to be chaotic again, Link smiled slightly, patted the table, and said in a loud voice, "The experiment begins!" With that, he stepped off the podium and pondered a question that had nothing to do with the classroom as he surveyed the situation: What would a loud and catchy name look like?

Like most fire magicians, Mr. Link is an amateur apothecary, or more accurately: a powerhouse of demonic addiction. And not long ago, he was lucky enough to make a breakthrough in his private brewing research, and the blind cat had developed a magic addiction potion that made people want to stop drinking it.

Not surprisingly, Link, as the developer of the specialty drug, was also the first addict. In less than 20 days, Link was 'uncomfortable' without drinking 500 milliliters a day, and he could only work and live normally after drinking 1,000 milliliters.

At this point, Mr. Link had to face a problem: making raw materials. The main food is very simple, and it is not difficult to use a few common fruits, but the last three special plant fruits that must be 'space-teleported' are very expensive, and no matter how cheap they are, they can't hold up a large amount, and the single life that has greatly improved since coming to Birdbeak Town has rapidly deteriorated, and even when I went to the slums last time to 'solve my physiological needs' I can't remember clearly.

Selling the specialty potion was the only option, and after a visit to the three new pubs in the centre of Birdbeak Town and the famous 'Red Chinese Restaurant', only one of them was willing to try to sell them, and Mr. Link had to come up with a good name for it.

It is not difficult to understand this kind of cold reception, the threshold of the magic addiction potion is there. Regardless of the water magic warrior's hard resistance to damage, even if it is a fire magician, he does not dare to rashly drink unfamiliar magic addiction potions, as for the other two systems and ordinary people, drinking one dies the other, and the market share is really limited.

However, after nearly a year of teaching chemistry, Link has not opened the door to a new world, not only allowing him to give up the promotion of rings from six rings to seven rings, but also greatly improving the fine changes and understanding of fire magic, the same magic, now only sixty percent of the strength can cause a significant double effect, and finally and most importantly, is a clear and open mind.

For example, in the past few days, according to some theories in chemistry books, Link has begun to separate the ingredients of special magic addiction potions, trying to eliminate impurities and toxicity, on the one hand, it can be more efficient to prepare medicines, and on the other hand, it can lower the threshold for drinking.

While Mr. Link was wrestling with a few alternative names, his train of thought was interrupted by the sound of glass breaking, and following the prestige, it turned out to be the most frizzy bear child, whose name sounded somewhat similar to the lingua franca horse manure.

Too lazy to blame anything, while motioning for everyone to continue writing the experiment report, Link walked back to the podium and made a note on the blackboard, then took out a new test tube and put it in the hands of the bear child with a bitter face, and joked: "I heard that you also broke the equipment in the morning physics class, plus this test tube, I suggest you go to the school doctor's office after school to get some healing ointment, which will probably be used at night." ”

There was laughter in the experimental classroom, and at the same time, they all guessed why the 'old fire demon', who was usually not smiling, was in a good mood today. At the end of the lab class, Mr. Link finally decided on the name of the potion: Green Mist, which was very fitting for the fluttering feeling after drinking it. At the same time, fifteen rewards were distributed as agreed, although there were only nine fire-type magic talents in this class, as for any insider trading, it was regarded as a small care for the juniors of the peers.

In the evening, he changed into a hooded outfit and came to the tavern with five bottles of green mist potion. In the midst of the noise, I whispered a few words to the bartender at the bar, and while waiting, I watched the surrounding drinkers drink the so-called alcoholic beverages newly developed by Tro Ling, and laughed out loud. Mr. Link, who had tasted the alcoholic beverage, knew that it was nothing compared to his own blue mist potion.

He fantasized a little about the situation where the drinkers were all holding the green mist potion, so he shook his head, as long as he maintained a certain amount of transactions, he was afraid that he would not be tired of doing so much. After a while, he was led into the back hall by the attendants.

"Sir, you're finally here, what do you call it? The white-skinned man who claimed to be the tavern steward greeted him warmly as soon as he saw him, and his attitude was a 180-degree turn from the last time.

Mr. Link was secretly happy in his heart, his face was impassive, he nodded and said indifferently: "Call me old bark." "Like last time, deliberately having a rough voice, revealing half of an old and densely wrinkled face under the hood, and dressing up as a very old person, can be regarded as a kind of self-protection that is not rigorous. When he was a teenager, he used to be a little mixed in the slums in his hometown, and Link, who had not set foot in the artisan area half a step in adulthood, only remembered this little trick.

The tavern steward greeted him warmly, and then introduced himself for a while, and then hesitated: "I don't know if you ...... this time."

Link didn't talk nonsense, and took out all five pot-bellied glass bottles from their wide hooded robes, "Green Mist Elixir." ”

"Good name!" the tavern keeper gave a thumbs up, then rubbed his hands together, "If there are five more bottles, the shop is willing to raise the price by thirty percent." ”

Mr. Link shook his head, "There are only so many, there are no idlers in Beak Town, and I can't make this thing at home every day." ”

This birdbeak town is a more concentrated and efficient artisan area, most of them are craftsmen, and they are a little idle for a short time in winter, and with the war with the Vorke Kingdom at the end of winter, everything is turning at a higher speed, and the words 'no idlers' are the truth.

"Understood! understood!" the tavern steward echoed with a smile, hesitated for a moment, and then said tentatively, "I wonder if Mr. Old Bark has considered specializing in this business?"

Directly shook his head and refused, after all, at this time, in Mr. Link's heart, as long as he had Qingwu to drink every day, he would be satisfied, and selling part of it was just to ease the economic pressure. As for opening a factory and running a business as advertised in the onion newspaper and becoming a millionaire, there is no interest at all, so where can the so-called 'sense of achievement' and 'superiority' have the medicinal effect of the Qingwu Elixir come refreshingly.

And there is a bachelor, and he is not too young, and after death, I don't know who will go to the cheaper money.

Don't talk nonsense with the tavern steward, complete the transaction smoothly, and agree on a share of two bottles a day, take the money and leave. At the moment before entering the gate of the community, Mr. Link, who always felt that something was wrong, paused, frowned slightly, thought for a moment, turned into a shop selling household utensils of all sizes at the entrance of the community, and bargained with the clerk for a long time, and then held a large steamer to settle the bill.

The moment I went out, I glanced left and right, and the street scene under the street lamp seemed to be normal at first glance.

Pedestrians in twos and threes, or walking in the corner, or workers returning late from overtime, or drunks returning from leisure and entertainment in the town center, several large passenger floating pallets speeding by, and a larger large floating pallet called a bus slowly stopped, and after many people went up and down, it slowly started.

With a light snort, he remembered that he was already a seven-ring, and under normal circumstances, the nine-ring powerhouse would not want to kill him instantly, and Link wanted to go home directly. But now, the cowardice of the unknown forces still prevails, and they think of a way to get rid of the tracking for a while. I have to say here that all kinds of criminal investigation TV series and movies still have a certain educational significance, and people who have not received this kind of education have really simple ideas. So, in the cool breeze of a midsummer night, Mr. Link simply walked around the neighborhood and swaggered into the house.

However, after the next few transactions, Mr. Link became more and more sure that things were not simple, but after thinking about it, his poor imagination did not give any reliable guesses, and he didn't know anything about his own power, which made Mr. Link start to be irritable, and he took advantage of the situation to increase the amount of green mist potion to drink, and incidentally, increased the amount of sales.

In terms of life, in addition to the teaching tasks of the affiliated middle school and the routine street patrol tasks of big citizens, he has devoted all his time to preparing Qingwu potion, and the smooth transaction process and the continuous inflow of money have also made him forget the research direction of eliminating toxicity and lowering the threshold for drinking.

It wasn't until he came home from work one day that Mr. Link noticed that there seemed to be something strange in the room, and his brain, which had been soaked in the green mist potion for a long time, barely turned a few times, and then he realized that all kinds of household items had slight displacements, especially in the kitchen of the part-time laboratory, where there were definitely more than one or two dishes that had not been washed for many days.

scolded a dirty word from his hometown, but Mr. Link was at a loss, first a kind of anger at being snooped on, and then he was afraid, what kind of hanging he looked like after drinking a large amount of green mist potion, Link himself knew quite well. If the home was invaded at that time, even an ordinary person could easily stab himself to death with a knife from the kitchen.
