Seeing this, Chen Ying sighed silently, and stepped forward to smooth Xue Zhi's back, feeling a little heavy.

Although there were only a few words, and the language was unknown, Chen Ying still understood.

Xue Rui must have another secret story when she was humiliated, and the key to this secret is Xue Zhi.

She lowered her eyes to look at the girl in front of her and opened her mouth, but after all, she closed her eyes and said nothing.

Xue Zhi had stopped sobbing, but the tears were flowing endlessly, and the whistling sound in her throat was occasionally heard, and it was quite difficult to breathe, so it was obviously not suitable to speak again.

Chen Ying beckoned to two maids and whispered: "You send Second Miss Xue back to the quiet room to rest, don't lead her to talk, she needs to recuperate now." ”

The two maids responded and helped Xue Zhi down, while Chen Ying turned back to the flower hall.

The order in the hall has been restored, the upside-down tables, mattresses and other things, all in place, Zhishi took a few servants, removed the debris around Xue Rui, vacated a space, and ordered someone to take a large rag, wipe off the water stains on the ground, unscrew the sewage in a wooden basin, splash the mud outside.

Xue Rui was still unconscious, Xu is wound hurt too much, even if she was unconscious, her eyebrows were slightly frowned, sweat was oozing from the corners of her forehead, and a few strands of hair stuck to her sideburns, adding a little weakness.

Liu's mother is careful, and she didn't know where to find two quilts, covered the key parts of Xue Rui's body, and tried to show people only with wounds.

However, this method can only be used temporarily, and under the continuous washing of the water, the quilt is almost soaked.

"Tell the truth, you can find a few more quilts and replace these wet ones." Chen Ying commanded softly.

Zhishi hurriedly went, and when Liu's mother saw Chen Ying, she also came over and said with a smile: "The principal forgives the sin, and the slave maid makes her own opinion, because she was afraid that the third girl would catch a cold, so she found something to cover her." Again, the hot water was mixed in. ”

"You don't have to make amends, you're doing a good job." Chen Ying bowed her head, raised her eyes and looked around, her eyes suddenly staring.

In the corner by the window, something caught her eye, and she took a few steps forward and leaned down to pick it up.

Xunzhen saw it from afar, afraid that she would want someone to serve, so she hurriedly followed, and took advantage of the situation to stretch out her head and look forward.

Chen Ying held in his hand a total of three things: a small wooden box with the lid opened and a groove dug out of it; a small celadon vase; A cork that has broken a small half.

Looking at these things, Chen Ying turned her head and called softly: "Mother Liu, please come here." ”

After speaking, he said to Xunzhen gently: "You go and get busy with yours, I don't have much to do here." ”

Knowing that she was going to talk to Mother Liu, she bowed and stepped aside, Mother Liu was already close to the left, so she stepped forward and bent down: "What is the matter with Principal Chen's call for slaves?" ”

"Do you recognize these things?" Chen Ying put a few things on the case one by one, and looked at her and asked.

Mother Liu glanced at it, her eyes suddenly flashed with horror, and she said with a white face: "Go back...... Back to the principal, this is exactly what our three girls are doing. ”

She pointed to the celadon vase, and her voice trembled slightly: "The third girl just took this small porcelain vase and poured that strange water on herself." ”

Chen Ying let out a low "hmm", reached out and picked up the small porcelain vase and embedded it in the wooden box.

These two things are obviously a complete set, and the groove of the wooden box is just embedded in the porcelain vase, and it is tightly seamless.

Chen Ying picked up the cork again and tried the size of the bottle, which was just right.

"It turns out that this is how she stores this strong acid." She whispered to herself.

At this moment, the east wind suddenly surged, blowing the window drawer a few times, and her voice was drowned out by the wind, and others could not hear it clearly.

Chen Ying's purpose in returning to the flower hall was to find these things.

Previously, because she was busy treating Xue Rui, she didn't care about it for a while, but now that she has found these things, it is a good explanation of Xue Rui's way of keeping and using this substance.

As for the source of this thing, when he spoke to Xue Zhi just now, Chen Ying had already figured it out.

Except for the experimental building of the girls' school, the Great Chu Dynasty was afraid that it would not be able to find another place to develop this substance.

This thought was born, and Chen Ying felt a sense of absurdity.

Because, if you get to the bottom of it, the source of Xue Rui's self-harm is Chen Ying.

In this year in the capital, Chen Ying continued to send a large number of books, pen, ink, paper, inkstone and other things to the girls' school, in addition, she also purchased a lot of strange things such as dansha, realgar, green alum, cold water stone, saltpeter and other things.

In the eyes of the Great Chu people, these are all Taoist pill practice materials, which is not surprising. In Chen Ying's eyes, this is the best raw material for chemistry laboratory classes, and she uses them as teaching materials.

And that's where the problem lies.

Chlorum can be refined into sulfuric acid;

Saltpeter can be used to refine methyl nitrate.

Sulfuric acid plus nitrate methyl is the basic formula for extracting higher concentrations of sulfuric acid. With the hands-on temperament of Chen Han and Li Nianjun, the possibility of them coincidentally producing a higher concentration of sulfuric acid is great.

Chen Ying exhaled heavily.

If these strong acids are laboratory products, then the way Xue Rui obtained them is easy to find out.

"At the end of the day, it's my management negligence." Chen Ying muttered softly, with mixed feelings in her heart.

When Liu's mother heard this, she didn't know why, thinking that Chen Ying had something to say, so she asked in a whisper: "The principal has something to explain to the slave maid?" ”

Chen Ying was awakened by her voice, thought about it, and said, "You come out with me, I do have something to ask you." ”

One wall spoke, she put away all the things on the case, turned around and walked out of the flower hall, Liu's mother broke her steps, and after a while, the two came to the corner of the corridor, which was where Chen Ying and Xue Zhi were talking.

The sky was still a little overcast, the distant mountains were covered with light mist, the shadows were too shadowy to see, and occasionally the wind came, and the vine leaves "rattled", and the remaining water droplets fell, as if it were raining again.

Chen Ying sat down on the lintel of the stool, slowed down her voice as much as possible, and asked, "Mother Liu, I take the liberty of asking." A year ago, on the night of the accident in Zhaoyuan County, what was the situation in the Zun Mansion, could you please tell me in detail? ”

She paused, and slightly accentuated her tone: "Just now, Miss Xue Er said a few words to me, but she seems to have a deficiency disease, and every time she is emotional, she is angry, I don't want to teach her to work hard, so I have to come to ask my mother." ”

"The headmaster can be a slave." Mother Liu was sincerely frightened, shook her hands a few times, and said with a smile: "You have something to ask, the slave and maid should report everything to you, but don't dare to ask for advice or not." ”

"Mom is so polite." Chen Ying said in a harmonious voice, stretched out his hand and pointed to the lintel of the stool: "You have been busy for a long time, I think you are tired, just sit down and talk." ”

Liu's mother refused to sit, Chen Ying gave in again and again, she thanked her, sat down diagonally, rested her hands on her knees, lowered her eyes and looked at her feet, but did not speak, as if waiting for Chen Ying to ask.
