Upon hearing Zhao Shi's confident answer, Ma Qian'an felt relieved. The flowers he cared for were about to bear fruit. How could he be unhappy? Ma Qian'an excitedly patted Zhao Shi's shoulder and praised him, "Good boy, I know you can do it."

Zhao Shi laughed and flattered him, "It's all the strong support of the leader. Without the care of the leader, I don't have the courage to measure this thing, so I don't have the idea of ​​solving the problems that arise."

"You guy, I'll just say something nice." Ma Qian'an smiled and praised Zhao Shi for being smart enough, knowing how to handle relationships flexibly and likable. Not all intellectuals are dull and not good at interpersonal communication.

"Wait, I'll show you something!" Zhao Shi's shoulder slanted, and he slid off the "bear paw" that Ma Qian'an slapped on his shoulder. He turned around and ran away happily. In the blink of an eye, Zhao Shi ran back, stood still and raised his clenched fist to Ma Qian'an's face and let go.

Zhao Shi spread his hands and held a test tube, which was half full of white crystalline objects.

“That’s it?”

"Yes, that's it." Zhao Shi nodded affirmatively,"

"Has done an experiment?"

"Don't worry! I've done the experiment according to Dr. Qian En's thesis, and all the infected mice have come alive." Zhao Shi couldn't suppress his excitement.

The two of them made such a fuss at the door, attracting Li Zhaolin and Zhou Yucheng. They swept over a lot of instruments that blocked their sight. When they walked closer, their eyes stared at the things held by Zhao Shi's palm.

Ma Qian'an hurriedly greeted him and called Li Zhaolin, "Welcome to check the work."

Li Zhaolin waved his hand, "It's clean and clean, I'm just here to take a look. I heard Jingyu say that the thing you made is better than sulfonamide. I was wondering if I could give me some first."

Zhao Shi then saw Li Zhaolin and Zhou Yucheng. He scratched his head and said in confusion: "Huh? When did you come?" Before Zhou Yucheng could answer, Zhao Shi looked at Li Zhaolin carefully and asked in a vague tone of indetermination, "Are you? You are Commander Li of the Third Route Army? You dare not recognize it. When did you come? I don't know."

Zhao Shi was too focused on his work just now, and he didn't even know when Li Zhaolin and the others would enter the laboratory.

Li Zhaolin was also very satisfied with Zhao Shi's work spirit. He praised him gently, which made Zhao Shi feel embarrassed.

Ma Qian'an looked at Zhou Yucheng who was following behind him and asked, "Old Zhou, why are Commander Li here for?"

Zhou Yucheng took a step forward, avoided Li Zhaolin who was talking to Zhao Shi, and pulled Ma Qian'an and said: "For the sake of the wounded, the last time he hit Ulaga, Zhao Jingfu, the political commissar of the Ninth Detachment, was shot in the thigh. He thought it was not a big problem, but who knew that he would burn when he came back, and the wound became suppurated. He also had surgery and used various drugs to prevent inflammation, but he couldn't control the ulceration of the wound. It's been more than ten days, and Commander Li is anxious." The Ninth Detachment belongs to the Third Route Army and is a subordinate of Li Zhaolin.

"Oh! That's the case." Ma Qian'an understood it, and recalled that he had not seen Zhao Jingfu recently. He was in the hospital and had to go and see it later. This was the old Anti-Japanese Allied Forces. He insisted on it in the Northeast until early July. He received the news and retreated to the Soviet Union, which was later than Ma Qian'an and his friends returned from Yan'an. In history, Zhao Jingfu died in July 40. Now it seems that the guy, the god of death, is still entangled with Political Commissar Zhao.

Saving people is like putting out a fire. After Ma Qian'an understood the situation, he immediately ordered Zhao Shi to take all the penicillin that had been purified and go with Li Zhaolin.

After Zhao Shi's medicine came out, he had not had a human test. After hearing what Ma Qian'an said, he immediately ran to a small cabinet excitedly and took out a large glass bottle of about one liter from it. Ma Qian'an took a look and saw that there was half a bottle of things inside, so he felt a little relieved.

According to historical records, Dr. Qian En's initial purified penicillin is only one teaspoon. According to the capacity of the teaspoon, it will never exceed 15 grams, and its purity is only 50,000 units. Compared with the purity of a million units per gram in modern times, it is really far behind.

After Dr. Qian En found the purified substance, he searched for a long time but no one was willing to try this new drug. It was not until an injured policeman tried Qian En's penicillin when he used up all kinds of treatment methods but failed to work. The results were very effective. He quickly controlled the infection to expand and saw signs of the ulceration of the wound. Unfortunately, there were too few medicines and they were used up quickly. In the end, even the medicine ingredients in the urine excreted by the wounded were recycled. It was still not enough, so he could only see the police die.

Several people asked for a car, and Ma Qian'an drove them to the hospital.

On the way, Ma Qian'an asked Zhao Shi, who was still excited, with concern, "Zhao Shi, what is the purity of your penicillin?"

"There are about 10,000 strains per gram, just 10,000."

"Oh? How do you measure it?" Ma Qian'an became interested. He was always worried that Zhao Shi didn't know the purity and did not know the measurement method. In this regard, he could not "guid" Zhao Shi because he himself didn't understand it.

"It's quite difficult. We first dissolve the bacterial seeds in pure water, then stir evenly extract a certain unit of water droplets, make a slide, check the number of bacterial seeds under a microscope, and then convert the amount of bacterial seeds in a liter of water. Then use these dissolved bacterial seeds to purify after various steps. The crystals that finally come out are probably estimated. Of course, some bacterial seeds must have died during the extraction process and become invalid parts. After mixing the water, the glass slide process is repeated, and it is repeated over and over again, and it is measured like this."

It's really troublesome. Ma Qian'an exclaimed in his heart. This science must be as rigorous as Zhao Shi.

When they arrived at the hospital, several people went straight to the ward. There was only one soldier in the ward taking care of Zhao Jingfu. The soldier recognized Li Zhaolin and quickly saluted.

Li Zhaolin leaned over and looked at Zhao Jingfu who was in a coma and asked the guardian soldier, "Why are they all so much? Are they getting injections on time?"

The soldier replied naively, "I keep cooling the political commissar and take medicine on time. It doesn't work. The wounds have expanded a lot. I heard from the Soviet doctor that it seems that I have returned pneumonia."

Li Zhaolin pointed to Zhao Jingfu on the bed and explained to Ma Qian'an and others helplessly, "This Xiao Zhao is disobedient. The Soviet doctor said that he would amputate him. If he had an amputation, he could save his life. He refused. He didn't believe in the doctor. He also said that he had been injured before, so he survived. This guy was afraid that the Soviets would have surgery while he was unconscious, so he called a naughty green to guard him and refused to allow amputation. Now, it's good that pneumonia is coming, and even amputation may not be cured."

"Zhao Shi, come on! Is there any danger?"

Zhao Shi hesitated for a moment, "It should be no danger. We have done experiments abroad, and I have also done experiments on mice, but I am afraid that if it happens."

"You doctor, don't say something depressed. Is there a better way? Take medicine! I'm responsible."

Under the gaze of everyone, Zhao Shi took out his medical bag, picked out a little medicine from the big bottle and dissolved it and sucked it into the syringe he brought.

Just as Zhao Jingfu was wiping the skin at the injection site, a doctor rushed over under the guidance of a nurse.

The thin doctor who broke in was named Bishkov, who was the attending doctor of Zhao Jingfu. He had been very upset these days. The Anti-Japanese Allied General named Zhao was stubborn and did not cooperate with his amputation request. This kind of injury and this infection could not be controlled at all. What can I do without amputation? However, even if I have surgery now, it may not be too late. Unless Zhao is extremely tenacious and can reduce his fever by himself, it will be a dead end. However, due to the doctor's duties, Bishkov still visited him on time and made various treatment methods, except for amputation.
