Nightboat has a good memory, she has memorized all the runes in the room during that time, and then drew all the runes on it according to her memory, and when all this is ready, she began to put these runes on the ground as if she were in a secret room.

She hadn't discovered the mystery of these runes when she was in the room before, but at the last moment, a wisp of yin wind came in and blew away the paper on the ground, probably because of fate and providence, and Yezhou finally found the mystery in those scattered papers.

After arranging everything, Yezhou picked up the pen and began to connect the lines according to the information on it, and after a while, she finally stopped, and the connected lines finally formed a circle.

Yezhou frowned: "This is ...... Array?"

Yezhou is not familiar with things like magic circles, but occasionally I have heard people talk about a sentence or two, when she is in the source of the vine, Hu Ying will also draw a formation when she opens the boundary seal, this array is similar to what she found in the source vine city.

"What's going on? Why is there such a thing in that room? What is this array for?"

What kind of accidental coincidence could she believe, if that secret room was left by Tuo Jiang, then this array must have been left by her, but why did she put this in the secret room? and why would she use such a secret way? Wouldn't it be nice to draw the array directly?

Yezhou had a puzzle in his head, and wanted to figure everything out by the way, but now it seems that things are getting more and more complicated.

Just as Yezhou was thinking seriously, suddenly the door of the classroom was opened, and Yezhou turned his head to look, only to see Mr. Sun walking in with a tired face.

"Yezhou, what are you doing here, and making a mess of the classroom?" asked Mr. Sun.

"I found something and I'm researching it, but I haven't figured out the truth, so I'm bothering Mr. Sun to take a look. "Night Boat Road.

Mr. Sun walked over and looked at the magic circle drawn on the ground, a little stunned.

"This is a circle, what are you doing studying this?"

"Mr. Sun doesn't know the use of this magic circle?"

Mr. Sun looked at Yezhou like an idiot: "I'm a pharmacist and not an alchemist, what are you doing studying these things if you have nothing to do?"

Yezhou was stunned: "Alchemy?"

"Why? You don't even know about alchemy? Then you still study magic circles? This kind of magic circle is generally something that can be used in alchemy, and it is very weird, there are no more than ten people who can do alchemy in the sky, and it is really not famous here, and because alchemy is too secretive, people have always had opinions about it, even more than the opinions of the pharmacist. ”

When Yezhou heard this, it suddenly dawned on her, it turns out that there is alchemy in this world, and she has never heard of it.

"Mr. Sun, I wonder if my mother also studied alchemy when she was alive?" asked Yezhou.

"You said that she is the strongest pharmacist in the world, and she is so focused on this, how can she have the time and interest to study alchemy? Anyway, I have never heard her mention it. ”

Mr. Sun's words made Yezhou stunned for a moment, and his eyes became entangled again, Mr. Sun saw that she was not in the right state, and asked, "What's wrong? Why did you suddenly ask about this? Could it be that you want to be an alchemist?"

Yezhou shook his head: "It's not that I want to be, I suspect that my mother was proficient in alchemy before she was born." ”

"What?"

Mr. Sun's face was puzzled, and Yezhou patiently explained to him the secret of the mysterious room and the runes, and gradually Mr. Sun's expression sank.

"Are you saying that the circle you drew was actually left by Ruojiang, and that Luojiang is likely to know alchemy?"

Yezhou nodded: "I don't know what kind of thing the pharmacy is researching, but I guess that my mother is likely to have added alchemy to her research, because alchemy is not popular in the sky, my mother didn't dare to tell others about it, in order to avoid being caught by others, so she hid the alchemy circle representing the research in this way in the soul crystal." ”

Listening to Yezhou's speculation, Mr. Sun still couldn't believe it, he had known Ruojiang for more than ten years, and they were together every day when they were researching, but he had never heard Ruojiang talk about alchemy.

"How is this possible, the medicine master and the alchemist are completely different, the power of the medicine master is healing, and the principle of alchemy is exchange...... Exchange. ”

When he said this, Mr. Sun suddenly paused, as if he had thought of something, his expression gradually became weird, Yezhou looked at each other suspiciously, but Mr. Sun didn't say anything, just wrote down the magic circle in front of him, and then left in a hurry.

Ye Zhou couldn't help frowning when he looked at the other party's back, but he didn't step forward to ask, and Ye Zhou was studying the magic circle for a long time in the future.

She searched through almost all the books in Qingdu Academy, but just like Mr. Sun said before, there are very few alchemists in Tiandu, and the records about alchemy are even more pitiful, she borrowed all the books on alchemy, studied day and night, and finally only figured out the principles of alchemy.

Equivalent exchange.

Yezhou sat alone in the classroom, probably so engrossed that he didn't even notice that there was an extra person behind him.

Qi Ran had been standing behind her for a long time, looking at the books in front of the other party, he couldn't help but raise his eyebrows.

"This is a book about alchemy, why did you suddenly remember to read this?"

Qi Ran suddenly spoke, and Yezhou was frightened by him, and turned his head to look at the other party.

"Why are you here?"

"On the way, I met Shuituo and them, and they said that you have been strange lately, so I will take a look. ”

"They like to worry about it. ”

Qi Ran smiled: "They care about you very much." ”

Yezhou didn't deny it, and continued to study things, Qi Ran looked at her for a while, and left quietly, but soon he came back with an extra hot porridge in his hand.

"I heard you didn't eat this morning, so let's eat something first, don't go hungry. Qi Ran said.

Yezhou was stunned for a moment and reached out to pick it up, but just as she was about to touch the bowl of hot porridge, Qi Ran's hand suddenly loosened, and the porridge fell upside down on the table, staining the book in front of Yezhou.

Yezhou paused and looked at Qi Ran in confusion, but Qi Ran just smiled softly and his eyes fell on the soiled book.

Yezhou followed his gaze, the two sheets of paper on the book were watermarked by hot porridge, and the contents of the two pages were combined, Yezhou looked at it carefully for a while, and suddenly realized that something was wrong.

"What is this?"

Nightboat pointed to the overlapping part of the book, which had only a small outline, but it looked very strange.

Qi Ran replied calmly: "That's a person, do you know what the taboo of alchemy is?"
