Fluorescent powder is a very low-level alchemy material. Its biggest function is to attach to an object and emit fluorescent blue light in the dark. Don’t underestimate this fluorescent powder, it is the nemesis of the advanced potion transparent potion. The guy who is sprinkled by the fluorescent powder will be lit all over. No matter how transparent you are, you will have nowhere to hide.

Moreover, although phosphor is a low-level alchemy medicine, its advanced drug flash powder is a very important material. You should know that flash powder explodes when it encounters fire and can flash out extremely bright white light. When facing the enemy, if you are surprised, it is easy to blind the enemy.

Moreover, if you want to make flash powder, phosphor is an indispensable learning technique. Because the pace of flash powder is almost exactly the same, but there are many differences in the materials.

The phosphor is diluted with fluorescent stone and placed in sulfuric acid. After diluting it into mud, the first step of making the phosphor is completed. Then bake, mix and stir the mud-like phosphor. After mixing and stirring the material into a mud, put it in an oven and bake it dry. Then carefully grind it into powder. In this way, the phosphor can be successfully produced.

During the process, it is worth noting that the dilution degree of fluorescent stone is too dry and cannot be turned into mud, and it cannot be stirred with several other materials. If it is too thin, it will destroy the characteristics of several materials and cause it to appear in addition to drying.

Then it is drying, and the drying level also has strict requirements, that is, it is necessary to ensure that the phosphor is baked to a loose and hard level. If it is too loose, it will turn into slag. If it is too hard, it will not be ground into powder. Only when it is not loose or hard can it be successfully ground into a very suitable and perfect phosphor.

It sounds very complicated. In fact, phosphor is the basic of alchemy medicine. Alchemists with more than half a year of alchemy experience can basically make them skillfully.

But Wan Xiang has no experience in alchemy, he only has the theory of alchemy. So the manufacturing of phosphor is very simple, but it is not something he, the guy who made phosphors for the first time, could make. Almost all, most guys who made phosphors failed the first time. Wan Xiang was the same, but he gave himself a dead order, that is, no matter what, he had to successfully make the phosphors in this class.

However, even if this class is a big class, the time is ninety minutes. But Wan Xiang has already spent sixty minutes. The degree to which he barely diluted the fluorescent stone has reached the standard.

And as he tried and explored again and again, all the alchemy students in the classroom were looking at Wan Xiang with sarcastic eyes. Because they had long discovered that Wan Xiang was the guy living with Ifia and Emil. In their opinion, Wan Xiang appeared here to learn alchemy because he had evil thoughts about Pandora, the beautiful witch teacher.

They really misunderstood Wan Xiang. However, Wan Xiang didn't care about their eyes at all. He forgot everything and focused on making it again. And the one just now, who had finally reached the standard, was thrown away without even looking at it.

Either don’t do it, and do it to the best you can!

During the failure of dilution, Wan Xiang has gradually mastered some tricks. Although the fluorescent stone has been diluted successfully, it can barely make fluorescent powder. However, in Wan Xiang's opinion, it has not yet reached the most perfect dilution range. So Wan Xiang threw away the fluorescent stone that had just been diluted without hesitation and continued to fumble.

Maybe no one noticed it. Seeing Wan Xiang throw away the diluted fluorescent stone, he thought this guy didn't understand any alchemy knowledge at all. The sarcasm in his eyes had been exposed again. If it were in the past, Wan Xiang would have been furious. But now, he has been completely devoted to the state of selflessness, and everything around him has been completely ignored.

"Dilution control, you can see the process of fluorostone melting. You can try it, constantly touch it with a glass rod, and feel the softness of the fluorostone. In addition, you should also carefully control the amount of sulfuric acid. You can put the fluorostone first, and then water it with sulfuric acid. If you feel that there is too much sulfuric acid, you can neutralize it with distilled water."

A full of intellectual voice, he skillfully reminded Wan Xiang in his ear. While thinking hard about how to control the dilution level to the best range. This reminder immediately gave Wan Xiang a lit up his eyes. He even forgot to thank him. Wan Xiang immediately discarded the diluted fluorescent stone and began to test it with concentration according to the other party's reminder.

This time, Wan Xiang suddenly felt that all the problems were dissolved in front of him, and the dilution process was very smooth. In a short while, he successfully reached the standard dilution stage. However, Wan Xiang thought that it was not perfect enough. The perfect fluorescent stone dilution point could be further improved. After the improvement, the diluted items and various materials could be successfully blended together. In addition, the baking time could be shortened by 45 percentage points.

Thinking of this, Wan Xiang suddenly stopped all the movements and began to think hard. Everyone saw Wan Xiang stop all the movements

I already thought that Wan Xiang was satisfied and gave up. So, I looked at Wan Jia with contempt. There was no reason, because the one who reminded Wan Xiang just now was Pandora.

Moreover, even Pandora now thinks that Wan Xiang is deliberately attracted to him, so he pretends to be so serious. He is full of dissatisfaction with the reminder just now. His eyes looked at Wan Xiang a little wrong, and there are so many rumors in Wan Xiang. He turned around and prepared to leave the student, return to the podium, and comment on the phosphor made by each student.

However, at this moment, Wan Xiang's eyes suddenly lit up and a smile began to appear on his face. His hands moved again, skillfully condensed a piece of ice, freezing the fluorescent stone into a particularly crispy way. After just dropping a drop of sulfuric acid, it began to mutate.

The fluorescent stone suddenly began to become very soft, as if it had melted, and gradually turned into mud. On the surface, it began to appear like bubbles emerging from the mud in the swamp, and gradually became softer and softer. After more than a dozen breaths, it turned into a perfect mud because of a drop of sulfuric acid.

"It's done!"

Wan Xiang shouted happily, and the expression on his face seemed to be like the first time he went home to seek credit for the children. All the innocent and bright smiles appeared. They were silly and silly. Suddenly, they looked very cute. In a moment, except for not dancing, they were already very innocent and cute.

Everyone was surprised by Wan Xiang's performance at this moment, but at the same time they were attracted by Wan Xiang's new dilution method. Even the witch teacher Pandora's eyes lit up and her unnatural heart praised.

At this time, Wan Xiang became busy again. He added ignition materials to the fluorescent stones that became mud-like after perfect dilution, which increased the effect of fluorescent stones. Then he began to spread the fluorescent stones, as if they were a big cake, and put them in the oven to dry.

"When drying, you should pay attention to the color. After the initial mixing, it will be gray, and then it will gradually spread out blue. When it turns completely blue, the drying level will be completed. Then take it out and cool for about three minutes, and then you can grind it into powder form!"

Wan Xiang didn't raise his head. He just nodded slightly. Now his attention was still very focused, because things had already reached this point. Even the witch teacher Pandora reminded him again. Don't interrupt Wan Xiang's serious and highly concentrated attention. So, Wan Xiang's eyes are still staring at the oven tightly, not even blinking.

Ordinary drying is about thirty minutes. Since Wanxiang uses a special dilution method and spread out method to dry, the process has been reduced to ten minutes. After waiting for ten minutes, it completely turned blue. Wanxiang immediately took out the dried fluorescent stone and placed it on the table to cool slightly for three minutes. He touched it slightly with his hand and felt it started to get a slight cold. He immediately pressed the entire glass trough on the table and shook it gently. The dried items in the entire glass trough were completely shaken into powder.

call!

Wan Xiang breathed a sigh of relief and wiped the sweat from his forehead. He still did not relax, but completed the last step seriously, carefully collected all the phosphors, and cleaned the entire table, perfectly making it slim. The bell of the end of get out of class finally rang at this time.

Finally caught up!

Wan Xiang was filled with joy and emotion because he successfully completed the production of phosphor. Although he didn't know the effect, he knew that he had not failed. So, when Wan Xiang was happily preparing to hand over his work, when he looked up, he was stunned.

Everyone in the classroom was looking at themselves with incredible eyes, as if they were looking at a monster, their eyes full of surprise and surprise.

Wan Xiang didn't know what was going on, but he suddenly saw admiration in everyone's eyes.

how so?

Wan Xiang didn't know that his seriousness and slight slightestness in the manufacturing process had already infected everyone present. Although they were all students who had several years of alchemy experience, they suddenly realized that compared with Wan Xiang, they were so pitiful. Therefore, gradually, their eyes began to change when they looked at Wan Xiang.

The initial irony has become admiration. At the same time, they also realized their shortcomings, which is that they were very unscrupulous. For a moment, admiration and self-deprecation filled the entire classroom. Wan Xiang didn't know what to do, wasn't it just to make a phosphor? Is this...as for this?

Slap~!

Suddenly someone clapped his hands gently, and then he saw the witch teacher Pandora calling all the students' souls back and said, "Okay, that's all for today's class. To be honest, I was very moved by this class." As he said that, Pandora looked at Wan Xiang and asked, "Do you like alchemy potion?"

"yes!"

Wan Xiang answered calmly, and then he heard Pandora continue, "Okay, if you don't understand anything in the future, you can come to me just!"

Wan Xiang's eyes lit up immediately and he said, "Really, I have many problems now, such as this..." As he said that, Wan Xiang shamelessly pointed at Pandora. With Pandora's eyes that were about to collapse, he followed her and lingered.

"I admire you! It's true that he is a master of picking up girls!"

A male student sighed from the bottom of his heart and all the students were misunderstood.
Chapter completed!
