After Su Jinxiu enriched and cultivated the collected mold, he first filtered it with a coarse cloth, and then added rapeseed oil after filtration, because Su Jinxiu vaguely remembered that penicillin was a water-soluble substance, and adding rapeseed oil could remove fat-soluble impurities.

Then Su Jinxiu adsorbed the penicillin dissolved in the water with activated charcoal, and then added vinegar and alkaline water obtained by boiling the juice with seaweed. Finally, after one filtration, crude penicillin was obtained.

But another problem also arises, the medicine is obtained, but these penicillins have not been clinically tested, and Su Jinxiu is not sure what the consequences will be after these things are injected into the prince, and if they are tested on small animals, small animals that have not had tuberculosis have been tested.

After Su Jinxiu told Cheng Ying the question, Cheng Ying looked at her suspiciously: "These long-haired steamed buns can cure the prince's illness?" Su Jinxiu glanced at him angrily, "Of course it's not a moldy steamed bun, didn't you see that I also added other things?" Don't mess with my things. Now the question is where do we go to find sick critters to test the medicine for the prince? ”

Cheng Ying scratched his head, "How do I know where to find sick animals, but we can find some tuberculosis ghosts to test the medicine for the prince." ”

When she heard this, she quickly shook her head and hurriedly stopped him: "No, how can we use people to test medicines, it is a trivial matter that these medicines can't cure the prince, what if they break others?" This is absolutely not a no-go. ”

Cheng Ying also felt that it was not good to test the medicine with a living person, but there was a deep-rooted thought in his mind: It was the honor of those tuberculosis ghosts to test the medicine for the prince, and the safety of the prince was related to the national community, how could the lives of several people be compared? If the lives of a few people can be exchanged for the prince's recovery, it will be a blessing in the world.

No, Cheng Ying saw that Su Jinxiu's face was very serious, and knew that she would not agree with her idea. Su Jinxiu herself is also at war with heaven and man: what does other people's lives have to do with him, if the prince's illness is not cured, he will also suffer......

What's more, those people have tuberculosis, and they know their fate very well, and they will inevitably die if they don't test the medicine, and if the drug is successfully developed, they will also benefit from it.

Thinking of this, Su Jinxiu hurriedly shook his head and said to himself: "Su Jinxiu, you are also a highly educated modern person, how can you harm other people's lives for your own safety, you must do something and do nothing, you must not do this."

Thinking of this, Su Jinxiu couldn't help but secretly despise herself, turned back to Cheng Ying and said, "You remember I told you, the prince's disease is contagious, you can go and get a little prince's saliva for the small animals, and we can do experiments when they are infected." After Cheng Ying heard it, he suspiciously went to the prince to ask for saliva.

After a period of breeding, Su Jinxiu got eight sick puppies, and she used a homemade needle to inject the puppies under the skin, but disappointing that after a period of time, none of the eight puppies were spared, and all died violently. Finally, after more than 20 days, penicillin was successfully developed to treat tuberculosis.

Su Jinxiu made an appointment with the prince and decided to start trying to treat the prince.

In the early morning of the next day, Su Jinxiu came to the prince's residence with the penicillin and syringe she had developed.

Su Jinxiu hurriedly walked in and found that Cheng Ying was already playing chess with the prince here, the prince heard the footsteps, but he didn't look up, just said lightly: "Are you sure you can cure the disease in this palace?"

She was still a little nervous, but when she heard the prince question herself, the stubborn energy in her heart overcame the nervousness, she raised her head and said calmly to the prince: "The little girl doesn't dare to guarantee that she will be able to cure the prince's illness, but the lives of me and my husband are in your hands, and the little woman doesn't want to die, so there is only one fight."

Seeing her like this, Cheng Ying hurriedly took over the conversation: "Prince atonement, since we went back, Jinxiu has been developing medicines for you, forgetting to sleep and eating, and not undressing, it is really for your condition, I believe in Jinxiu, if I can't cure your illness today, I am willing to die." The prince's face softened slightly: "Since you said so, I will believe you once."

After that, the prince looked at Su Jinxiu, "Come on, how to treat it?" ”

Su Jinxiu took out a homemade syringe and said, "I need to use this thing to inject the medicine into your body, there may be some pain." Although the prince was unheard of about this treatment method, and had a natural resistance to this unknown method, it had reached this point, and the prince simply let go of his guard and stretched out a white hand.

Just when Su Jinxiu was about to be injected, there was a sudden commotion from outside the door, the prince frowned, retracted his hand, and scolded loudly: "What's going on outside the door?" Why the noise for no reason? ”

"Emperor, can't the queen mother come to you to have a look?" A majestic voice directly overshadowed the prince's reprimand. The prince's face turned from anger to shock, but he quickly collected his emotions, the prince smiled, and strode out of the door, "The son didn't know that the queen mother had arrived, and he was disappointed, so please atone for the queen's sins." ”

Soon, Su Jinxiu met the most noble woman in the world - the current queen. This queen was not wearing a phoenix robe that Su Jinxiu often saw in TV dramas in her previous life, but a simple long skirt, and there were two little eunuchs beside her, who followed her step by step.

The queen's face couldn't see the joy and anger, "Emperor, the mourning family heard that you found a wild girl to treat you somewhere, so I couldn't rest assured, so I came to see you." "The prince bowed down and was grateful" There is a concern of Queen Lao's mother, Erchen has recently felt a cold, and happened to hear that this woman has excellent medical skills, so he called her to come over to treat Erchen. ”

The queen's eyes swept over Su Jinxiu's body, causing goosebumps on Su Jinxiu's body.

"This fox was born well, but it's a pity that Su Daji is reincarnated, specializing in sucking human blood. Emperor, you don't take your body seriously, there are doctors in the palace, why bother to find this kind of fox from unknown sources to treat you? ”

Su Jinxiu, who was on the side, was angry when she heard these words. But she knew very well that the woman in front of her was powerful, so Su Jinxiu just lowered her head and scolded her silently in her heart.

"I've seen the queen's mother, Su Jinxiu is the wife of the grass people, not the reincarnation of Daji, she is only thinking about His Royal Highness the Prince's body, and she has never done anything to suck people's blood."
