Supreme Pharmacist System

　　　　 Zhou Wen followed the old lady to the inpatient ward and found out that her son was not suffering from a minor illness, but advanced liver cancer, and time was running out.

After 　　 and other male nurses helped Guo Bochun wipe his body, the old lady sat on the bedside, tremblingly opened the insulation box, picked up a plastic spoon, and fed the bony, bloodless old man on the bed.

　　 Zhou Wen looked at it with the eyes of true vision. This little old man is named Guo Bochun, 72 years old this year, and the old lady Zhang Jieru, 93 years old this year.

"I will not eat."

　　 "Be obedient, take a bite."

　　 "Hmm..." At the old lady's repeated requests, Guo Bochun ate a spoonful of rice with soup, but as soon as he swallowed it, he immediately vomited it out in the next second, "Oh...cough cough cough..."

　　 The old lady put down the lunch box and took up the bedside paper towel to wipe it.

　　 Zhou Wen, who was standing by, also helped, and at the same time asked: "Where are his children?"

　　 "They are all dead."

"what……"

　　 Zhou Wen was a little embarrassed.

　　 The old lady said with a deep smile: "My grandson was a firefighter. He rushed into the fire to save people and never came out. He was only 22 years old that year, and he should be about the same age as you now.

　　 The second grandson is JC, but also died on duty. "

　　 Zhou Wen's body stiffened, and an unspeakable soreness blocked his throat, "Your grandchildren are all amazing people!"

　　 "Yes!" The old lady sighed with a smile, revealing infinite sadness.

　　 After wiping it off, the old lady continued to feed. Although Guo Bochun could not eat, she insisted on swallowing.

　　 Then he vomited again soon.

　　 After vomiting, Guo Bochun experienced intermittent pain. At first it was just "humming", but then it became heart-piercing.

　　 Zhou Wen knows that most patients with advanced liver cancer will have severe pain.

　　 is mainly caused by the rapid enlargement of the tumor, compression of the liver capsule, traction pain, and tumor necrosis to stimulate the liver capsule, and some are caused by the rupture and bleeding of cancer nodules on the surface of the liver.

　　 Looking at Guo Bochun's appearance, the cancer cells have completely collapsed, and analgesic drugs such as Mexcontin and pethidine hydrochloride have no effect on him.

　　 Although the old lady had seen life and death a long time ago, she couldn't help but wet her eyes when she saw her son wailing on the hospital bed, but she was helpless.

　　The only thing she can do is to use her wrinkled palms to hold her son's hand tightly, giving his mother the strength.

　　 Zhou Wen is a sentimental person, he can't see such a scene the most.

　　 I can’t help if I want to help...

　　 "No!"

　　 At this moment, Zhou Wen suddenly flashed a flash of light in his mind, and he thought of the "biological pain relief formula".

　　Although this drug cannot treat liver cancer, it should relieve Guo Bochun’s pain and allow him to enjoy a moment of peace in the last moments of his life instead of dying in endless pain.

　　Biological painkillers have a simple production method. The extraction of plant raw materials is the same as that of animal genomic DNA extraction, but the method is slightly different, and the experimental equipment is readily available.

　　The only question now is, do you want to help?

　　 Just then, a familiar reminder sounded in my ear, [ding! The task conditions have been fulfilled. Do you want to submit the task immediately? 】

　　 Zhou Wen was stunned, and after the reaction came, he was suddenly ecstatic.

　　 Hope day and night, unexpectedly, when he almost gave up, the task was actually completed like this.

　　 He opened the system page, clicked submit, and then saw that the task of becoming a full-time employee was really completed.

　　 At the same time, a task prompt popped up again.

　　 [Task: Zhang Jieru's wish.

　　 Explanation: Guo Bochun is suffering from illness and pain. She hopes that there is a medicine that can relieve his illness.

　　Requirement: Produce biological analgesics within 48 hours, and relieve Guo Bochun’s pain.

　　Reward: 500 subject experience, 500 points, one opportunity to open the box (black iron)]

　　 Before Zhou Wen can check it carefully, the phone in his pocket rang, but Wu Yan called.

　　 Zhou Wen walked out of the ward to connect.

　　 Wu Yan said beamingly: "I can tell you one thing, your organization is already down."

　　Although Zhou Wen already knew it, he was still very happy, "I'm so happy to hear the voice of the senior sister, should your system be down?"

　　 Wu Yan participated in the hospital’s public recruitment examination at the end of last year, and wanted to change from a contract worker to a career editor. At that time, her results were quite satisfactory, but she had not been notified or announced.

Wu Yan let out an "um" and couldn't restrain her excitement and said, "Thank you this time! According to the boss, Lin Huaidong, the head of the expert team of the Provincial Center for Disease Control and Prevention, was in front of us at the special meeting on epidemic prevention held yesterday. The leaders of the Municipal Health Bureau praised you and the business level of our hospital by name, and asked the whole province to learn from our hospital!"

　　 Zhou Wen said excitedly: "Fuck it, really?"

　　 "Really! Then the boss pushed forward and submitted my admission score and your employment information again, but I didn't expect it to be approved today."

　　 Wu Yan is so happy.

　　 This time it was the light of Zhou Wen. The top leader was happy and passed her a big pen. Such an opportunity is rare in a lifetime.

　　According to the current situation, like Jiang Hexuan, Wei Zhaogong, Dong Wenying, and Xu Jiajia, they will want to change the organization in the future, I am afraid it will be extremely difficult.

　　 The two chatted for a while, and Wu Yan said that she would treat her to dinner.

When Zhou Wen heard this, he quickly said: "Forget it, I will have a numb scalp when I eat now, and I will talk about it later. And I think we should not talk about this matter. We have to consider the mood of Xu Jiajia and Wei Zhaogong, you say What?"

　　 "Well, you are right. I was so proud~"

　　 The two chatted for a while before they hung up.

　　 Zhou Wen put away his phone, turned his head and glanced at the ward.

　　 The old lady grabbed her son's hand, muttering something in her mouth, as if she was telling him about childhood.

　　 No matter how old a son is, in the eyes of his mother, he will always be a child.

　　 Zhou Wen’s surging mood was poured cold water on his head by the tear-jerking scene in front of him.

　　 He looked deeply at the mother and son in the ward, then turned and left the inpatient department.

　　……

　　 Zhou Wen first went to the big pharmacy, spent 20 yuan, bought all the several medicinal materials that needed to be used, and then returned to the reagent preparation room of the testing center, and began to prepare the needed reagents.

"For example, EDTA, NaCl, SDS, glucose, sodium diethyldithiocarbonate, PVP, mercaptoethanol, RnaseA mother liquor, chloroform, pentanol, ethanol solution, NaAc, etc., a total of more than 20 kinds.

　　The ratio of each extraction buffer and reagent is different, and has strict requirements.

　　 Fortunately, Zhou Wen has learned about reagent equipment during this period, otherwise the reagent equipment level alone would stump him.

　　 After two hours, I finally prepared all the reagents needed.

After 　　, he returned to the comprehensive laboratory on the sixth floor.

　　 Wu Yan has left, and there is no one in the comprehensive laboratory.

　　 Zhou Wen turned on the system and took a look. When he was preparing the reagents, the task had already triggered the conditions and started automatically.

　　 Then he started making biological painkillers.

　　 First is to extract the DNA of medicinal materials.

　　 Add extraction buffer to a 50ml centrifuge tube, and then preheat it in a water bath at 70°C;

　　Put 10g of the purchased salvia miltiorrhiza leaves into mortar, UU reading www.uukanshu. Com is then ground into powder after adding liquid nitrogen, immediately pour it into a preheated centrifuge tube, shake it vigorously, and keep it in a 70°C water bath for 30 minutes.

After 　　, add the chloroform/pentanol/ethanol solution, mix it upside down and let it stand for 10 minutes at room temperature to separate the water and organic phases...

　　 The upgrade of biochemistry gave Zhou Wen a deeper understanding of the reaction of organic chemistry, making it easy to conduct experiments, and with the assistance of the true vision eye, every step of the reaction is clear.

　　 Now that DNA extraction is a piece of cake for him, there is no failure at all.

　　The only problem is that the first time I do plant DNA extraction, it will be slightly rusty, and the speed will be a little bit slower.

　　 Three hours later, a high concentration of Salvia miltiorrhiza DNA was extracted.

　　 This is just the beginning.

　　 Next, extract "Water Decay Clothes".

　　 The same steps, the difference is that with the first experience, the second time is more handy and faster. It only took two and a half hours.

　　 After the extraction of the water-stale clothes was completed, he was just about to continue with the extraction, who knew his stomach was groaning.

　　 Looking at the time again, it is already 8:30 in the evening, no wonder.

　　 But Zhou Wen didn't want to eat, because there are 5 strains of DNA to extract.

　　 I have to do DNA amplification when I look back, so time is not enough.

　　 Finally, he took out a natural and pollution-free apple from the system inventory.

　　 He thought of the poisonous oath he had made last time, and said to himself: "This is the last time, whoever eats it again is not a human being."

　　 After hesitating for three seconds, he held up the apple and took two mouthfuls, and swallowed it directly before the taste was transmitted to the brain...
