After Chen Ying's words, Hua Yujiao said firmly: "Listening to the principal's words, this female master is afraid that she will only hurt her epidermis, and it should be fine." It's not that the slave boasts, but the slave's medical skills make it so that as long as it is a traumatic injury, even if there is only one breath left, the slave can pull people back from the ghost gate. ”

"Leave a line" finally came back to his senses at this time, and also helped on the side: "Principal, rest assured, Sister Lan is the best at treating external injuries, and the gold sore medicine handed down by her ancestors is miraculous, and the medicine can cure even the most serious injuries." ”

After speaking, she glanced at Hua Yujiao, and suddenly sneered: "Sister Lan is determined to be the number one poison doctor in the world, and often makes some sugar pills. ”

Hua Yujiao was poked in the foot by her, and she couldn't scold her immediately, but because Chen Ying was on her side, she couldn't say anything, so she could only throw a knife at her.

This scene in Chen Ying's eyes also reassured her.

"Leaving a line" is very familiar with Hua Yujiao, and the doctor she introduced must not be wrong.

When the group entered the flower hall, Xue Rui's injuries had been cleaned, so Chen Ying ordered someone to carry her to the couch and set up a screen.

At this time, Hua Yujiao smiled, took the medicine box in her hand, looked very serious, bowed to Chen Ying, and turned behind the screen.

In the next treatment process, Chen Ying gave carte blanche to "leave a line", and ordered Zhishi to stay, telling her to "go to the laboratory building to find me if there is something", and then confessed to Hua Yujiao, and left with Xunzhen.

The origin of the strong acid substance in Xue Rui's hand is not yet known, and the laboratory building must be investigated.

When Chen Ying rushed over, Chen Han and Li Nianjun both sat honestly in the rest room and listened to Chen Xiang's words.

Chen Xiang had already heard about Xue Rui, and when she knew that the things she was holding were likely to come from the laboratory, she immediately knew that this must be the fault caused by Chen Han and Li Nianjun again.

Chen Ying's arrival can be regarded as a disguised relief from their encirclement.

She invited them to the laboratory and immediately asked, "Have you ever experimented with alum and saltpeter?" ”

The substances contained in alum and saltpeter, together with some technological techniques, can produce concentrated sulfuric acid.

Hearing this question, Chen Han and Li Nianjun glanced at each other, and Chen Han raised his hand and shouted "report" in accordance with the regulations of the girls' school.

Chen Ying nodded with satisfaction and smiled at her: "Very good, please tell Master Chen about it." ”

Chen Han then got up and said, "Report to the principal, half a month ago, Xiao Lizi and I ...... Li Nianjun...... Classmate, I took the green alum from the warehouse, and a few other things, and put them in the distillation pot to boil, and then added something else, and the smell of cooking was very pungent, and I accidentally spilled a little, and my clothes belt was also eroded. ”

Her face was a little ugly, and her voice lowered: "Because I was in a bit of a hurry that day, what did we get out of that sour water, the two of us have only been thinking about it for a long time, and we ...... Didn't think about it either. ”

She held back her voice and lowered her eyes to silence.

She also knows about Xue Rui, if she says that she has no shame in her heart, it is impossible. It's just that she has never been in the habit of admitting her mistakes to others, even if she feels guilty at the moment, her head is still high.

Chen Ying didn't blame him, and asked, "Then how did this sour water get into the hands of Master Xue again?" You gave it to her? ”

"Report to the principal, we don't." Chen Han raised his eyes, but his eyes were very firm: "Classmate Li and I have never taken anything out of the laboratory. ”

Li Nianjun also nodded on the side, his face was as pale as paper, and he raised his hand timidly and said, "Report ...... Report to the principal, the students have something to say. ”

Chen Ying didn't say anything, only nodded in agreement.

Li Nianjun got up, lowered his head and said in a low voice: "Principal, I don't blame Master Chen for this, it's all the student's fault." On that day, Master Chen left beforehand, leaving the students alone. Because the students had forgotten that day, when they remembered that the sour water was still in the pot, the students thought that they would come back to clean up after cleaning the classroom, and they didn't lock the door, so they went back to the teaching building first. ”

"After that, did you come back and lock the door?" Chen Ying asked.

Li Nianjun shook his head, so sad that he almost cried: "The student ...... that day After cleaning the classroom that day, I helped the acting principal move the exam papers, so I forgot about it. When the students came to the lab the next day, the sour water was gone. The student thought it was burned dry, so it didn't ...... Didn't think much of it. ”

She rubbed the corners of her eyes with her sleeve and sobbed: "Principal, the student is wrong, the student hurt Master Xue, and the student is ......."

"This matter has nothing to do with classmate Li, it's all my fault." Chen Han interrupted her loudly, and her eyes were a little red: "Classmate Li is a student, but I am a master." The student is at fault, and the sin lies with the Master. If the principal wants to punish me, I am the only one who will be punished. ”

She straightened her back, bit her lip and twisted her eyebrows, trying her best to show the momentum of the teacher, but the hand hanging by her side was trembling slightly.

Chen Ying looked at her for a while and sighed: "In this matter, you did it wrong, and I did it wrong." ”

Chen Han and Li Nianjun were both taken aback, and they both looked up at her.

Chen Ying shook her head and said nothing more.

It has become clear that the two Madahars produced strong acids by accident. And Xue Rui probably happened to pass by the laboratory and hid this strong acid by his side.

After all, she had had had a terrible experience and lacked a sense of security, which was purely instinctive and probably not even aware of it.

Putting his thoughts down, Chen Ying looked at the two of them and said loudly: "Do you know what is the biggest mistake you have made? ”

She glanced at Chen Han and Li Nianjun in turn, and said in an accentuated tone: "Your biggest mistake is to treat scientific experiments as child's play. ”

She showed a look of regret and seemed to sigh: "It is true that the unbridled imagination is the torch that lights up the light of science, but if there is no precise deduction, fine calculation, and accurate measurement that follow, how is the difference between scientific experiments and dancing gods?" ”

When the two of them heard this, they were silent.

Chen Ying looked at them, did not continue, and instead began to announce the punishment of them.

"Chen Han, as a master, but you were so casual in the process of experiments, and finally caused the students to make a big mistake, I will punish you in the name of the principal to clean the toilets of the whole school for a month." Chen Ying took the lead, and then turned to Li Nianjun:

"Give you a month to complete two math study problem books, and the accuracy rate must be 90%."

At this point, he glanced at the two again: "When you have completed the punishment, when will you be able to enter the laboratory building." ”

"Yes, Headmaster." Li Nianjun cried, and the shame on his face became thicker.

The punishment could be said to be very light, and she was excited.

Chen Han was unconvinced.

"Didn't the principal say he was also at fault? Why not be punished? She was so stiffened by the neck that her eyes almost shot out of her eyes.

Chen Ying said calmly: "At the morning meeting next month, I will review in public and go to the kitchen to be a helper for a month." ”

Chen Han choked, and he had nothing to say.
