The day after deciphering how the Eighth Prince delivered the message, Daohua got up early and asked Qin Xiaoliu to go back to Ningmen Mansion. At noon that day, he saw him coming with many things.

After Xiao Yeyang saw it, he picked up a transparent conical cup and said, "Didn't you ask me to have Liulichang make these things before? Why did you move here?"

Daohua directed Qin Xiaoliu to put the things in the pharmacy: "You will know later."

Gu Jian pursed his lips and stood watching. Since he had an apprentice, half of the area of ​​his pharmacy does not belong to him. It was even worse this morning. The apprentice occupied some of his space and put a long

The table goes in.

At this moment, watching his apprentice continue to move things into the pharmacy, he felt that there might be no room for him in the pharmacy in the future.

Iron stands, alcohol lamps, measuring cylinders, plastic-tipped straws, distillation bottles, burettes, mortars, jars and other glassware are all placed on the table by rice flowers.

"Okay, you go out, and I will tell you when I get the things out."

With that said, he pushed Xiao Yeyang out.

Xiao Yeyang was withdrawn, looked at the closed door, and glanced at Gu Jian: "Master Gu, do you know what Daohua is going to do?"

Gu Jian snorted: "I'm not the roundworm in her belly, how do I know?" With that, he left with his hands behind his back.

Xiao Yeyang was silent, took a look at the pharmacy and went back to the house. Now that he has cracked the method used by Uncle Eighth Prince to deliver messages, he must make good use of it and try to accumulate more credit. Today is the eighth day of the first lunar month, and Yan Wenkai and the others should go out.

Got an errand.

Daohua worked in the pharmacy for more than two days. On the morning of the eleventh day of the first lunar month, she walked out of the room. As soon as she came out, she jumped up to Xiao Yeyang and handed him a note.<

/p>

"There is my secret on this note, you need to figure it out."

Xiao Yeyang glanced at Daohua who was in a good mood, took the note, opened it, and found nothing written on it: "Did you... take the wrong note?"

Daohua shook her head and said: "How could I get it wrong? Please crack it quickly and let me see what you are capable of."

Xiao Yeyang frowned: "But you didn't write anything on it."

Daohua smiled mysteriously: "You haven't checked it yet, how do you know I haven't written anything?"

Xiao Yeyang looked at the rice flowers, picked up the note and studied it.

Grandma Gu and Gu Jian sat aside and watched, with curiosity on their faces.

Seeing Daohua's proud face, Xiao Yeyang frowned. Gu Jian endured it, but finally couldn't bear it anymore, stood up and walked towards Xiao Yeyang: "Show me."

Xiao Yeyang handed the note to Gu Jian.

Gu Jian looked at the white paper in his hand and looked at his apprentice with some suspicion. Is this girl trying to trick Yang boy on purpose?

Suddenly, Xiao Yeyang received a blessing: "Go, light a candle and come over."

Soon, Defu came over with a candle.

Xiao Yeyang quickly put the note on the candle flame and baked it.

Daohua saw it and smiled: "Okay, you actually know this."

Xiao Yeyang looked at Daohua faintly: "I know this is not strange, but you know it is a bit strange."

Daohua's expression was stagnant. Oh no, she was so proud.

"Ahem~"

Dao Huajian rubbed her neck and said, "I'm so knowledgeable but I can't do that."

Xiao Yeyang did not continue to pursue the matter. Seeing that there were no traces on the fire-baked paper, he asked doubtfully: "Did you use any potion to write on it?"

Daohua immediately asked: "Why, has someone already used potion to write on paper to deliver messages?"

Come on, after hearing this, Xiao Yeyang and Gu Jian both knew what kind of lawsuit Daohua was fighting with them.

Xiao Yeyang: "Of course there is, I have seen relevant records in the palace library, but it seems that there are not many such practices, mainly because the potion is hard to come by." As he said that, he looked at Daohua.
p>

"You couldn't tell me that you were just making potions in the pharmacy these two days, right?"

What she made didn't impress the ancients. Daohua felt a little disappointed. She pouted and went to the pharmacy. Soon, she came out with two glass bottles.

Looking at the colorless and transparent liquid in the glass bottle, Xiao Yeyang and Gu Jian's eyes flashed.

Daohua opened one of them, dipped some liquid into it with a cotton swab prepared in advance, and then smeared it on the paper. Soon, a line of words was revealed on the white paper.

"Xiao Yeyang is a stupid pig!"

Defu was a quick talker. After reading the words on the paper, he immediately retreated with his neck curled up.

Xiao Yeyang watched Defu leave with a chill. After he could no longer see anyone, he picked up the note and read it carefully: "Hey, the handwriting is getting blurry?"

Daohua: "After a while, the words will disappear completely."

Xiao Yeyang's eyes were bright: "This thing is good for delivering news." Jin Lingwei's job is to collect and deliver information, so it is just for this.

Daohua smiled and said, "Isn't it? Although the Eighth Prince's method of delivering messages is secretive, if the messages were more frequent, it would be too time-consuming to search for them word by word."

"Using my potion is not that troublesome, and it is absolutely safe. Unless there is a matching potion for displaying characters, otherwise, even if you ask the gods, you will not be able to detect the message."

Gu Jian suddenly said: "Why are the words on the note so small?"

Daohua immediately raised a smile: "It's because Master has good eyesight that he discovered this so quickly." After saying that, he took out a gold pen as if to offer a treasure, "I use this to write."

Gu Jian took the pen and looked at it: "You are really luxurious, using gold to make your pen."

Daohua smiled: "Isn't it very high-end and classy?"

Gu Jian glanced sideways at her, took the paper, wrote a sentence on it with a pen, and then imitated rice flowers, dipped them in the potion and applied it on it.

Daohua quickly stretched her head and looked over: "What is it written? Let me take a look."

"Yan Yiyi is also a stupid pig!"

Looking at the revealed handwriting, the smile on Daohua's face froze for an instant, and she looked at her master with some words.

Gu Jian was quite happy: "It's a good sum, I'll keep it for my teacher."

When Xiao Yeyang heard this, he became anxious: "Master Gu, can you give me this money first? I will have someone make one exactly the same for you."

Gu Jian quickly put the pen into his arms and said two words simply: "No." After saying that, he walked to Granny Gu and sat down again.

Xiao Yeyang still wanted to persuade, but was held back by Daohua.

"I still have them over there. I asked the master at the gold shop to make a few more and give them to you later."

Hearing this, Xiao Yeyang suddenly laughed: "Okay."

Daohua pointed to two bottles of transparent potion and said: "This bottle is for writing, and this bottle is for displaying words. Don't get confused in the future."

Xiao Yeyang: "Is this made for me?"

Daohua glanced at him sideways: "Aren't you talking nonsense? I don't need this."

The smile on Xiao Yeyang's face became deeper and deeper.

Daohua said again: "You have to use this potion sparingly. The materials for making it are a bit hard to find."

Xiao Yeyang: "Tell me the materials I need and I'll get them." Just as he was about to reach out and put away the potion, Gu Jian spoke again: "Leave some of the potion for me too."

Xiao Yeyang was a little unhappy: "Master Gu, what are you doing with it?"

Gu Jian stared at him: "Can I use it for research?"

Xiao Yeyang: "...Okay, I'll leave some for you."

Gu Jian was a little speechless when he saw him scratching his head. At the same time, he glared at his apprentice angrily. It turns out that girls are outgoing, and when they have good things, they don't know how to honor their master first.
