Du Dian looked at the powder in some bottles and jars on the table next to her. These bottles and jars were labeled, but there was no text on the javelin, but all kinds of peculiar symbols were drawn, some were the sun, and some were the sun and the five-pointed star overlapping. , some are hooks, and so on.

"What is this?" Du Dian asked.

Nightingale saw the bottle he was pointing to, and said strangely, "Don't you recognize this symbol?"

Du Dian thought for a while, then shook his head and said, "I don't know."

"Don't tell me you haven't memorized the basic alchemy symbols yet?" Nightingale asked in surprise.

It was the first time Du Dian heard the words "alchemy symbol", and he was slightly stunned. Fortunately, there was a mask to cover it, so that the other party did not notice the expression. He secretly said in his heart: "Alchemy symbol? The function of the symbol is usually used to mark something. , I see, this should be something similar to a mathematical symbol."

This is not recorded in Rothyard's Alchemy Notes. Du Di'an guessed that it was too elementary, so there was no meaning to record it, and immediately said: "Yeah, I haven't memorized it yet, all my things have been left with my teacher. My teacher is dead, and the things have been seized by the goddamn Holy See, do you have a complete collection of alchemy symbols here, can I borrow them?"

Nightingale looked at him suspiciously, but after hearing that Du Dian called "The Holy See of Light" a "damn", he dispelled his doubts, and pointed to a shelf next to him, where there was a thick book with a black cover, "There, Take it and see for yourself, but remember not to break it, I have this one."

Du Dian nodded quickly, "Thank you very much."

Picking up this book of alchemy symbols, Du Dian was just about to open it and take a look, only to hear Nightingale say: "Go to another place to read, such as a small warehouse, I'm going to experiment."

Du Dian came over knowingly and came to the small warehouse she was referring to, which was a little messy, with tools for cleaning the alchemy room and some broken filters.

Du Di'an didn't care either, just sat there casually and flipped through the alchemy symbols.

I saw a dazzling array of alchemy symbols displayed in rows, with text explanations below the symbols. Du Di'an soon saw the sun symbol he saw earlier. Among alchemists, this represents gold!

"No wonder there is golden powder in the bottle, and the amount is very small." Du Di'an murmured and continued to read.

Time passed without knowing it.

Du Di'an was completely immersed in it, carrying these symbols with his heart. Through the explanation at the beginning, Du Di'an knew that this alchemy symbol originated from the astrological symbol of the fortune teller. With the decline of the fortune teller, the astrological symbol has gradually evolved into an alchemy symbol by the rising alchemist, and it has become a unique alchemical symbol system.

After the alchemist completes the experiment, the recorded content is usually a pile of alchemy symbols. If you are not an alchemist, you can't understand it at all. Therefore, memorizing this book of alchemy symbols is the basic requirement of an alchemist. one!

When Du Di'an was a third of the way down, he heard the voice of a nightingale from outside the warehouse door: "Is the hound there, it's getting late, it's getting dark, we're going home, do you want to stay here all night?"

Du Dian was stunned for a moment. He didn't expect time to pass so quickly. He immediately closed the book and opened the door. Seeing Nightingale and the poisonous snake standing at the door, he said, "I'm going back too, let's go together."

"That's fine." Nightingale nodded.

The poisonous snake glanced at the book in Du Dian's hand and smiled: "When Nightingale told me, I still didn't believe it, I didn't expect you to know this by heart, tsk tsk, you are an apprentice among apprentices, um, you should be called an apprentice, haha"

When Du Di'an heard his joke, he smiled slightly and said, "I have a poor memory, and my back is slow."

"I think you love to be lazy." The viper said in a tone of "I understand you": "At the beginning, I had a headache when I carried this, and I tried all kinds of excuses to escape, but in the end, my teacher forced me personally, I just The one who will memorize it is Nightingale, who has a smart mind. I heard that it took only about a week to memorize this one, so what a shame for me who has memorized it for half a year!"

Nightingale smiled and said, "How can you say it so exaggeratedly? I didn't know it well for a week, and it took half a month to fully memorize it."

"That's also very powerful." Viper said sadly.

Du Dian put the book back in place and said, "Are you coming tomorrow?"

"Of course." Viper said without even thinking about it.

Nightingale shook her head and said, "I'll see the situation. If there's something wrong, I won't come. If there's nothing wrong, I'll come over."

Du Dian nodded and said, "I'll come over tomorrow too."

"Okay, it's getting late, let's go back." Nightingale looked at Du Dian and the poisonous snake and said, "Which one of you will go first?"

"I'll go first." The poisonous snake was not polite, waved to Du Dian, came to the corridor outside the hidden wall, and climbed out.

"We'll go out in a few minutes," Nightingale said.

Du Di'an nodded, knowing that she was worried that she would go out too much at one time, which would easily attract attention, and if she left one after another, everyone had time to sort out their masks.

After a while, Du Di'an left the second. He climbed into the alley and saw that no one was paying attention to the street at the entrance of the alley, so he put away his mask, but he still wore a mask on his face, covering most of his face, and wearing mask on the street. It is not an alternative, and most of them will be considered by others to have a disease, and no one wants to get too close.

Just as Du Di'an was about to go home along the shortcut, he suddenly smelled a familiar smell, and couldn't help but be startled, a ray of light flashed in his eyes, turned, and walked towards the other side of the street, walking with his head down.

Not long after Du Di'an left, a little boy appeared at the entrance of the alley, frowned and looked at Du Di'an's departure direction, and said to himself a little angrily: "I'm still wearing a mask, so be careful!" Saying, Taking a deep look in that direction, he turned and left in the other direction.

Not long after he left, at the corner of the street, Du Di'an appeared sideways, looking at the back, frowning slightly, I didn't expect that the poisonous snake did not leave after coming out ahead of time, but hid beside him, probably to see his true nature. face.

"It seems that we can't take it lightly in the future." Du Di'an secretly said, and at the same time firmly remembered the other party's face, this is a fatal handle of the other party in his hands!

Du Di'an tilted his head to look at the alley. It was estimated that Nightingale was about to come out at the moment. He thought about it and gave up the chance to peek at her real face. After all, she didn't treat herself like this.

Turning around and leaving, Du Dian went around a few streets to make sure there was no familiar smell around and came to the corner of a street. When there was no one, he quickly took off his black robe and rolled it up, then quickly left here and took a detour home.
