"The boiling point of water at one atmospheric pressure is called a heat rate. If you change it to Celsius, it is 123.4 degrees. ”

In the transit space, Chen Yi looked at the thermometer in the device and recorded it in a notebook with a pen.

Among the wizarding apprentices, there were already more accurate units of measurement, from length, weight, to temperature. The difference is that these units are only defined for the convenience of wizard slots for experiments, and ordinary people hardly use them.

A unit like heat doesn't mean much to ordinary people.

However, when dispensing potions, it is quite important to have a temperature unit. Because the processing of various raw materials is almost always at high temperatures. As for whether the number is one or one hundred and twenty-three .four, there is not much difference. They just need to have a standard to refer to.

For Chen Yi, it is of great significance to change to a unit on the earth. In modern society, in terms of the accuracy of measurement, it is absolutely beating the other world.

When wizards prepare potions, it is like doing a chemical experiment, adding a little more or less of a certain material, and the temperature is high or low, which will lead to the failure of the preparation.

However, as long as there is no error in the material ratio and every step in the whole process is carried out in strict accordance with the requirements, the results of the experiment will not be deviated.

Recently, he has been soaking in the transit space, doing a lot of experiments, and successfully improved a more precise formula, the amount of each ingredient, refined to a few tenths of a gram. The temperature is also controlled to less than 10 degrees Celsius.

To optimize this recipe, he experimented dozens of times. The materials he had accumulated when he opened a pharmacy in Porter City were consumed.

He estimated that the materials were worth more than a thousand gold coins. I have to say that learning to refine potions is really very expensive, and it is not something that ordinary wizards can afford.

And that's just the simplest of things. The effect is to refresh the mind, and after taking it, it can make people concentrate and improve the efficiency of meditation. It is an indispensable auxiliary medicine for some apprentices who are severely eroded by negative energy and cannot concentrate.

At the auction, he had seen this potion in auction, and the transaction price was about five bottles of one magic stone, which was very stable. In other words, only if the success rate exceeds 20%, can we guarantee that we will not lose money.

This is not easy, there are as many as seventeen kinds of materials for this potion, and each material has to be processed first, if one of these materials is not handled properly, it will lead to the failure of preparation.

For third-order apprentices, there are not enough means to monitor subtle changes in temperature, and many times, relying on the experience accumulated from repeated failures. When you first start learning, the success rate is often miserable.

As soon as Chen Yi came up, he bought several sets of chemical experiment equipment with the idea of chemical experiments, as well as an industrial-grade temperature sensor.

In the beginning, he also kept failing, and then he kept adjusting. It was only at the eleventh time that the formulation was finally successful, and then, according to the data of the successful time, the success rate began to increase significantly. By the end of the day, the success rate was close to 90%.

"It's so easy to make money with a civilization backed by it." He sighed in his heart that even if he didn't sell gold and silver in the future, he would be able to earn countless fortunes just by dispensing medicines.

Of course, to rashly sell potions in large quantities is to seek death. The three major organizations will never let go of a good pharmacist, and will definitely try their best to recruit him into the organization, and will not allow him a chance to refuse.

"The difficulty of preparing the 'Burning Elixir' is much more complicated than this elixir, and Black Sunshine only has one plant, so it must be guaranteed to be successful at one time."

He wasn't sure right now, and thought to himself, "It seems that we have to go to the anomaly, collect more materials, and improve my proficiency." ”

It's been a month and a half since the last time I left the Atlas.

"I don't know what's going on over there, has it calmed down."

He was thinking about the situation in the other world, and what he was most concerned about, "Did Drew succeed?" ”

Drew's situation at that time was extremely bad, and impacting the wizarding realm was his only chance, and if he succeeded, he jumped into the dragon gate and let him roam the vast world. If you fail, you will only die.

"Let's go."

He hung the "Judgment" behind him, put on a loose black robe, activated the ring, and traveled to the other world.

Whew-

The biting cold wind, carrying snow particles to his face, he looked up at the gloomy sky, and the falling snow was full of beauty.

"It's snowing."

As a southerner, it was the first time he had seen the scene of snow with his own eyes, and he was somewhat happy in his heart, reaching out and watching the light snowflakes fall on his palm, bringing a trace of coldness.

In the blink of an eye, the snowflakes had melted into droplets.

He looked up and saw that the mountains around him were covered in a layer of white.

Glancing back at the mountainside not far away, Drew was hiding. Behind this hill is where Potter City is located.

"Drew, I hope you've made it."

He thought silently, withdrew his gaze, and left in the opposite direction of Potter City.

He has too many secrets, and he is reluctant to meet a wizard before he has the corresponding strength, even if for now, this wizard is friendly to him.

He was unwilling to put his safety on the possible goodwill of others.

Ask yourself, if he finds out that Percy is hiding some kind of secret, he will definitely try to find out, if it is a great chance to find out that Percy's secret, can he resist snatching it?

…………

"My lord, there is Rose City ahead."

On the carriage, a middle-aged man who looked like a steward said respectfully to Chen Yi.

Chen Yi lifted the curtain and looked at the city not far away, just looking at the tall city, which was more majestic than Potter City, and nodded slightly at the middle-aged man, "Okay, let's enter the city." ”

This middle-aged man is the steward of this caravan. Chen Yi walked halfway and happened to run into this caravan and asked to go along. When the steward of the caravan saw that he was wearing a black robe with gold edges, he did not dare to refuse, and gave him the best carriage, and waited carefully along the way.

From the mouthful of the steward, he also roughly figured out the major events that had happened in the past month or so.

As he had guessed in advance, the three major organizations had sent official wizards to investigate the matter, and the entire city of Potter had almost been turned upside down. During this period, many unorganized apprentices were implicated and liquidated for no reason.

The most famous of them is one of the top apprentices in Potter City, on a par with Drew. When facing a wizard, the slightest disrespect, was burned to ashes by a fireball, once again showing the world the strength of the wizard.

As soon as Chen Yi heard it, he guessed that the three major organizations were killing chickens and monkeys, and Drew had killed so many people from the three major organizations, if there was no explanation, it would be a big loss of reputation for them, since they couldn't find Drew, then take the apprentice with the same name as him to vent their anger. Let others know what will happen if you offend the three major organizations.

This is the sorrow of the weak, even if you make compromises, when the strong want to kill you, they only need a trivial reason, and even, they don't even need a reason.

Today, the three wizards are still in Potter City.

As for Drew, no one has found his whereabouts so far. There is no news of the appearance of a new wizard, whether he is dead or alive, Chen Yi is not clear.

He was going to go to Shengyao City to join Nina and the others. The destination of this caravan is the Rose City in front of them, and after entering the city, they are about to break up.

"By the way, I heard that there is a wizard looking for a great knight on a bounty, is there such a thing?" Chen Yi suddenly remembered the matter of Marcas's bounty, stopped the steward, and asked.

"Yes, sir."

"That was before the Porter City Auction." The son of a mentor at Ulis'an Academy, who was killed by a Grand Knight, offered a bounty on a bottle of 'Lynn' if he could catch the Grand Knight and bring it to him. ”

"Lynn's potion, that's a big deal." Chen Yi had a peculiar smile on his face.

The steward said, "At the beginning, many people were moved, and the first to find him were eight third-order apprentices, and as a result, these eight adults all died. Dying under an extremely terrible magic weapon, before the auction, was the most sensational thing. ”

"You know quite a bit." Chen Yi glanced at him.

The steward smiled flatteringly, "We went about doing business everywhere, and we heard more news. ”

"Well, that's good." Chen Yi took out a bag from his arms, "This is your reward." ”

With his rich experience, the steward knew that it was a bag of silver coins, and the number was dozens, and he said in fear, "It is my honor to serve adults, where do I dare to ask for my lord's money." ”

"Take it." Chen Yi casually threw his hand on the table, "Tell me about the appearance of that big knight." ”

"Thank you, sir." The steward glanced at his expression carefully, trembled his hands, held the bag of silver coins in his hand, and hurriedly said, "That big knight is very recognizable, he is an Oriental, with black hair and black eyes, yellow complexion, his height should be slightly shorter than that of adults, and he should be good at swordsmanship." ”

Chen Yi listened to his description and asked, "Isn't there a portrait?" ”

"Nope." After the steward finished speaking, he added, "I think such an obvious appearance can be recognized at a glance even without a portrait." ”

Chen Yi looked at him and couldn't help but smile, "Yes, such a look is indeed easy to recognize." ”

The steward didn't know what he was laughing at, so he could only laugh with him.

"Alright, there's nothing else to do, you can go out and get busy. Once I'm in the city, I'll leave on my own. Chen Yi restrained his smile and said to him.

There was a sense of relief in the steward's eyes, and he said, "Yes, sir." ”

After the steward went out, he lifted the curtain again, looked at the majestic city, the Rose City, and thought of a name in his heart, "Sauron Family......
