At this moment, Ye Guyun and the three of them left the laboratory and moved to Archmage Osma's luxurious study, not to prepare for any serious and profound academic discussion, but to show the two of them his treasures over the years. Pen % fun % Pavilion www.biquge.info

A large, thick, dusty hardcover book with a locked surface was removed, with a line on the cover that read, "Osma's Works."

The archmage was very proud, Frank was very excited, and Ye Guyun was very happy, and he couldn't be more happy.

"Presumably this is as priceless as Avis's notebook!"

"Such treasures can only be hidden deep in the bookshelf and sealed in dust...... What a waste! What a pity...... I can't bear it!"

"Why do they always have a lot of treasure but don't know how to use it?...... Well, it's not their fault, the whole world is limited by the thinking of the whole era......

The archmage returned to his seat with the hardcover book in his hand, wiped away all the dust with a wave of his hand, then went to the lock, opened the book, skillfully turned to a certain page of it, looked up at the two of them, and said with a smile: "This is a record of the old man's life's work!"

However, before he could say anything, Frank, who couldn't wait, had already preemptively blocked his next words: "Hey, my esteemed teacher! You have it! Don't show off! I know, the book is very good, and you are also very good, okay? Should we hurry up and get to the point?"

"Stinky boy!" the archmage glared at Frank hatefully, turned his head, and said to Ye Guyun, "I still don't understand why I have to use that design......" he shrugged, "but if it were to arrange the insulation, I would have a better option here than the magic circle." ”

The archmage shoved the open book in front of the two of them.

"This is one of my prides, an alchemical paint that can withstand high temperatures. Originally, it was used on top of armor, but with just one layer, it can be turned into an excellent fire resistance equipment. Guess who's this for?"

"Red Dragon, or Fire Elemental!" Frank blurted out.

"Aha! it's the Red Dragon!" the Archmage smiled, striumphant, "When I was young, my companions and I swore a crusade against a red dragon that was a curse. But you know, the Red Dragons are not idle, they are definitely one of the most powerful species in the main plane, and even the most professional, experienced and excellent adventurers dare not say that they will be able to win the battle, so we were still very young at the time and had to make a lot of meticulous preparations. It was in response to the red dragon's terrible flame breath that I developed this fire-resistant paint. ”

"And then?" After a pause, the curious baby Frank couldn't help but urge.

"Later, ahem, I forgot, it doesn't matter, don't mention it. Let's hurry back to the topic......" The archmage turned his head, forcibly ignored Frank's dissatisfied eyes, and said to Ye Guyun seriously, "I think this fire anti-paint will definitely be able to meet your requirements, as long as you brush a few thick layers on the inner wall of the kiln, it can play a good role in heat insulation, and you don't have to bother to arrange additional magic circles!"

Ye Guyun gave a thumbs up, but he didn't speak, he didn't know what words to use to describe his ecstatic mood at this time-overjoyed, smiling, happy, ecstatic, let's go together! I, Ye, didn't pick someone, and I didn't know how to pick it!

Originally, it was precisely because he couldn't make refractory bricks that he tried all kinds of excuses to urge the archmage to arrange the so-called heat-insulating magic array, but he never imagined that the solution he got in the end would be much more than expected--alchemical paint that can withstand the flames of dragons? This is not scientific! I know with my toes that this meow is definitely better than ordinary refractory bricks! It is more than enough to replace it! Oh no! This seems to be a bit overkill...... Now, not only the lime kilns that are urgently needed in front of us have been settled, but also the various furnaces that will be used in the smelting industry, which will be rolled out on a large scale in the future, have also been solved.

Fantasy is good, fantasy is wonderful, fantasy is all kinds of awesome and there is no need to explain! I love this fantasy world!

After the excitement, he calmed down and began to consider the most practical series of problems, so Ye Guyun hurriedly asked: "What are the indicators of this coating? Is its performance stable enough? What is the service life? Is it easy to prepare? and what is the cost?"

Archmage Osma was so dizzy by this string of words that he felt in his ears that he didn't know where to start for a while, so he opened his mouth, but then he couldn't say a word. Ye Guyun didn't care either, because when he turned his head, he realized that he was thinking badly, and there were many issues that didn't need to be considered at least temporarily, such as service life, preparation difficulty and cost.

This is not a light industrial product that needs to be manufactured on a large scale, but just an interior paint that needs to be used in a few smelting furnaces (or cement kilns) in a single city, and the amount used is extremely limited.

Just think about performance.

Waving his hand, Ye Guyun asked again: "Please tell me first, how many degrees Celsius can this coating withstand?"

As soon as the words came out, I was dumbfounded again, this world obviously does not have the concept of Celsius.

Ye Guyun had no choice but to say it again: "Can you specifically describe the flame resistance of this paint?"

Well, fire resistance, that's fantastic!

Archmage Osma finally understood this time, and after thinking about it, he replied, "I'm sure that it can withstand the flame breath of the Red Dragon in the prime of life three times head-on, it can effectively insulate the wearer from the heat on the surface, and it can reduce the continuous fire damage by 80%!"

These descriptions are really not what I wanted......

Ye Guyun then asked, "What is the power of the flame breath of the prime-aged red dragon?" I mean, is there any specific representation of the image, for example, it can melt something in an instant......

However, Archmage Osma was clearly misunderstood: "Oh, Saphius, can I understand that this is your question of the prime-aged red dragon or me?"

"No! Ye Guyun could only smile bitterly, "I just want to know the data, the exact data in detail." ”

"Data, what data?" the archmage wrinkled his old face, full of puzzlement, couldn't figure it out, simply didn't get entangled, shook his head, and began to explain, "The power of flame breath? well, it must be able to easily melt stone - in many stories of evil dragons attacking the city, you can always see the description of the battlements on the city wall being melted by a breath, and it must be able to melt steel - ordinary iron shields can't hold twice, armor can't be separated, and even some magic treasures with better texture can't last long!"

The archmage spread his hands: "So, when he thinks he will win, the red dragon always tries to avoid using the spit attack, because it is easy to destroy all kinds of equipment, treasures and gold coins that the target may carry! Hmph, the red dragon is such a greedy and evil reptile!"

Ye Guyun actually didn't listen to the sarcasm at all, and he had already pondered to himself.

Not to mention the stone, it can melt steel, proving that the temperature of the flame breath is at least higher than the melting point of the steel, which is high enough, and considering the "drag" of its attack mode, (the relatively diffuse covering contact attack in a short period of time is similar to that of a flamethrower, but the persistence is obviously much worse, and most of the time the contact with the object is not sufficient in terms of time or area), and the reverse deduction shows that its real temperature may be a standard higher than the melting point of steel - it has to be said that the "spitting" of these big reptiles It's horrible.

However, this fire-resistant coating invented by the archmage can withstand such terrible heat! This means that when used as a refractory material, it is definitely far beyond class!

Merely......

Three times, this fire resistance paint can only withstand the instantaneous heat from the dragon's breath three times......

Thinking of this, I have an idea.

Raising his head, Ye Guyun looked at the archmage who had been paying attention to him: "Mr. Osma, I think this paint still needs to be improved. ”

The archmage was stunned when he heard this, and asked with a little hesitation, "Performance... Not enough?"

"No!no!" Ye Guyun hurriedly denied, "In fact, the fire resistance of this paint is greatly surplus, we are only used as a heat insulation for the calcination kiln, and it does not have to reach the level of being able to withstand the dragon's breath!"

"So?"

"Frankly speaking, I think the performance of your fire resistance coating is too extreme, yes, it can withstand extremely terrifying instantaneous high temperatures, but it only has a very limited service life......" Ye Guyun stretched out three fingers, "Three times, it's really too little, this is completely unacceptable! Think about what kind ......of environment is in the calcining kiln?

"I see!" exclaimed Frank, clapping his palms, "if you want to use this paint in a calcining kiln, you must make it more balanced and adapt it to the application environment in the calcining kiln!

"Yes. Ye Guyun smiled and nodded, "Of course, it is the most perfect to be able to do it without degrading performance!"

"Is that possible?" asked Frank.

"Then I'll have to ask Mr. Osma. Ye Guyun turned his head to look at Archmage Osma.

The archmage kept brushing his beard, frowning and pondering for a long time before pouting and saying, "It's difficult, but it's not impossible. It's just that...... The cost of such a paint would be extremely high! It would be a ridiculous number! It would be extremely unrealistic! It would be extremely cost-effective! So I don't think there is a need to research, manufacture, or even discuss it. ”

"It's not necessary? How could it be!" Ye Guyun immediately retorted, "How can there be only one product for fire anti-coatings? There are medium and low-end universal ones, and there should also be high-end special ones! Moreover, in any case, cutting-edge technology has its own place of application! Even if you can't find it now, you will definitely be able to find it in the future! The current investment should be a technical reserve for the future!"

After a pause, he said: "In fact, it can be done smarter, more reasonable, more scientific and more profit-seeking." According to the fire resistance, from the highest can resist the dragon's breath, to the lowest can tolerate the melting point of stone, such a wide range, can be divided into a number of different grades, research and development of corresponding products, in order to meet the different needs of different markets! Of course, this needs to be realized one by one by Mr. Osma -- don't be too troublesome! This is a business that can bring a lot of wealth! If you want to make your life a little more prosperous in the future: easily maintain the dignity of the nobility without worrying about research funds...... You just can't miss this. Besides, at the end of the day, it's just a slight improvement on an existing product!"

"Tsk!" ...... the archmage flattened his mouth, "you don't even know how much work is involved in this......" he shook his head and sighed, "But after all, I don't have to say yes obediently?

"Hey, my teacher, how do you say it like you're reluctant......" Frank teased without knowing whether to live or die, and then he was imprisoned by Archmage Osma with a wave of his hand, and the blue energy rings were tightly bound to his body, and even his mouth was sealed.

"Stinky boy, sit down, shut up!"

Regardless of the distress look handed by Frank, Ye Guyun knocked on the table: "Next, let me tell you a complete account of Mr. Osma's work tasks in the next few days......"

"Phew, I'm not old enough to remember!" the archmage glared at Ye Guyun, "Isn't there just three things to come and go? Arrange and operate the magic circle to produce a batch of so-called 'cement' that is urgently needed; study how to arrange the magic calcination kiln; study the fire resistance coatings of various grades! In order! Yes and no?"

"Your Wise ......"

Ye Guyun hurriedly offered his praise, but was interrupted by the archmage before he could speak.

"I'll state that fire resistance paint must be my last unplanned research! It will be interesting, but I can't spend my precious time again and again on the '' things you have come up with! Sephoeus, you must give me a clear letter! When will the real chemical research begin?"

Ye Guyun suddenly became stumped: "I can only say, as soon as possible." I'll compile Fundamentals of Chemistry as soon as possible, and when the time comes, you'll be able to do as much research as you like......"

"I hope so. ”

"Definitely!" Ye Guyun had no choice but to solemnly promise again, his eyes moved, and fell on the "General Catalogue of Osma's Works" spread out on the table, his heart was itching, he couldn't help it, and tried to ask, "Mr. Osma, can I take a look at this masterpiece of yours?"
