Chapter 13: Men like hands, feet and women like clothes

Biquge EbookFREE.me, the latest update of the Cantonese silly concubine: the latest chapter of Miss Seven Doctors!
Gu Yanxi was taken aback. Although many words were still incomprehensible, he understood the word "poisoning".
"What, poisonous? Let the subordinates do it."
Ye Liuli shook his head, "It's not that I treat death as if I'm dead, but that I just heard that I have tried to refine salicylic acid. I have never tried it myself. I still need to explore myself. How can I guide you? Since there is a risk of poisoning, I'll do it myself, and you all step back. "
"No! The princess must not be poisoned!" Gu Yanxi's voice was firm.
Ye Liuli smiled, "I can't be poisoned, can you? If your prince knew that I had poisoned you, wouldn't you kill me? As the saying goes, brothers are like hands, feet and women like clothes, aren't they?"
Gu Yanxi laughed, "The princess looks away."
Ye Liuli shrugged. "Can't you see, how many years of your relationship with your family's grandfather, I have known him for two days? If we both fell into the water at the same time, he must save you but not me."
"..." Although the truth is such a truth, how can Gu Xixi listen to it? Why is this friendship spoke out of Ye Liuli's mouth, adding some ambiguity?
Finally, the salicylic acid was refined by Ye Liuli and Gu Yanxi together.
The girl heard that it was "toxic", so she wanted to run, and when Ye Liuli asked to leave, she fled.
After the time of a fragrant incense, the water of boiling willow bark has been boiling for a long time. With the heating, the liquid continuously evaporates, the liquid becomes more concentrated and the volume decreases.
"Gu Jun, step back, try not to touch the water and gas," Ye Liuli's voice was calm. "Water vapor containing salicylic acid is corrosive and harmful to the respiratory tract and the retina."
Gu Yanxi wanted to refute, but the other person's tone was convincing with an irresistible majesty.
"The princess is also careful." He simply stepped back two steps.
Gu Yanxi pulled a piece of mask into his mouth, leaning back as far as possible, leaving only a hand wrapped in a towel, holding the spoon and stirring continuously in the pot.
Time passes by every minute.
Finally, the liquid in the pot was completely dried. On the wall of the iron pot, there was a wave of white crystals. This crystal was salicylic acid.
Salicylic acid is not only a raw material for the pharmaceutical industry, it is used for the preparation of aspirin, sodium salicylate, salicylamide, analgesic, phenylsalicylic acid, and Xuefang-67. Used in the dye industry to prepare mordant pure yellow, direct brown 3GN, acid chrome yellow. Used as a rubber vulcanization retarder and disinfectant preservative. It is also widely used in cosmetics, as a preservative in cosmetics, and even in food.
This salicylic acid cannot be used directly. It must be further purified to become phenol, and then aminophenol is reduced by heating and purification with hydrochloric acid and iron powder. The final product is the prototype of modern daily medicine ... paracetamol.
Ye Liuli swears that this is the worst and most dangerous experiment she has done since she was exposed to chemistry experiments in junior high school, but she has to do it.
The day passed almost in the blink of an eye, and it was so late in the evening.
When Ye Liuli collected the final product in a bottle, he almost cried with excitement, feeling as if Columbus discovered the New World of America, as if Robinson opened up a new world on a desert island.
Suddenly there was a loud noise from afar, and then someone ran over, "Master, division, it's not good!"
Ye Liuli looked up and gave a smooth look. It turned out that he was one of the two disciples of the military doctor. Was there something wrong with the King Wang?
