doctor knife in hand

The room with fifty petri dishes was locked by Song Heng's order, and no one except Lu Jin could enter.

At the same time, Song Jiajun, who followed him to watch the whole process of production, also received his military order that Lu Jin must not reveal a word about the development of new drugs to anyone.

What's more, when talking about the people in the Duke's mansion, their mouths are stricter than anyone else's.

Regardless of success or failure, strict confidentiality is required.

Although Song Heng doesn't know the principle, he understands its value.

No matter how nervous Song Heng was, Lu Jin only cared about the efficacy of his penicillin.

This extraction process was calculated by him over and over again. He had confidence in himself, but even so, he still felt a little uneasy.

According to the medical and technological level of this era, there is no hotbed for penicillin to be discovered at all, because Lu Jin, who traveled through time, brought the possibility.If it is really successful, he doesn't know how much impact it will have on this era.

Maybe it's better, maybe it's worse. Lu Jin, a small person, can't imagine it. What can be seen now is that there will be more soldiers surviving in the Great Chu army, and the balance of victory will be tilted more towards the Great Chu.

Seven days later, all the people gathered again in this temporary laboratory of the British government, looking eagerly at the fifty numbered porcelain whiteware placed on the table.

With the lid on, no one knows what's going on inside.

"Abai, you set it up, Alan, you record it."

After Lu Jin finished speaking, the brothers and sisters glanced at each other, and suddenly felt that their shoulders became heavy.

The two teenagers stood by the table, Sun Bai looked at Lu Jin and said, "Master, I'm over it."

Lu Jin nodded, there was no sound around, it was so quiet, it seemed that even the sound of breathing was subconsciously lightened.

Sun Bai then stretched out his hand to the No. [-] Petri dish, but before he could touch the lid, he suddenly heard a swallowing sound, which immediately attracted his attention.

General Pang rubbed his hands together and whispered, "I'm nervous."

No one laughed at him, because everyone was in the same mood.

Sun Bai took a deep breath and lifted the lid.

Following his movements, someone subconsciously took a step forward and stared at him.

"how is everything"

Sun Bai watched for a long time, and when He Lan came over, he shook his head and said, "No change."

It is impossible to succeed all at once. The concentration of No. [-] is the lowest, and failure is also expected.

Lu Jin said, "Continue."

Sun Bai then lifted the second cover, this time he didn't dawdle like the first time, after observing, he said, "No change."

"Alas" came a small sigh from around, it seemed regretful.

However, Lu Jin's expression did not change, and he only urged, "Go on, the changes should be obvious at a glance, and there is no need to dawdle."

Sun Bai nodded, and after flipping two, he was quick to strike.

"Number three has not changed."

"Number four has not changed."

"No change to number five."

"NO.15 unchanged"

He lifted fifteen of them in a row, but so far he hasn't found the white circle that Lu Jin mentioned. He couldn't help but look up at Lu Jin, who frowned slightly and said, "Go ahead."

Sun Bai then continued to lift the lid.

"NO.16 has not changed."

"NO.17 has not changed."

"NO.18 has not changed."

"NO.40 unchanged"

He paused for a moment, and suddenly there was a shadow beside him. Lu Jin walked over and looked down at the lifted petri dishes, all of which were of the same pale yellow color.

"Master" Sun Bai and He Lan called softly.

Before, Lu Jin could comfort himself that the concentration might not have reached the standard, but now, he suddenly wasn't sure if something went wrong during the process.

Penicillin actually failed

While thinking wildly, I suddenly heard Song Heng say, "There are still ten more, let's keep going."

Hearing this, Sun Bai glanced at Lu Jin, who nodded slightly.

"Number 41 unchanged."

"Number 42 unchanged."

Seeing that there were fewer and fewer left, Lu Jin's face became more and more serious. Everyone was prepared for this, but when Sun Bai opened the last one, he said with difficulty, "NO.50NO.50No Variety"

After speaking, he lowered his head, not daring to look at Lu Jin's expression.

As a record, He Lan also wrote those three words very sadly.

For a while, just like the beginning, there was still no sound around, and everyone looked at Lu Jin.

Lu Jin looked at the fifty petri dishes that were opened, all of which were light yellow in color, and told him that what he did before was wrong.

He was a little lost for a while, he didn't know which step he was wrong.

Song Heng walked along the table, glanced at the table lightly, then put his arm around Lu Jin's shoulder and said, "This is a failure, right?"

Lu Jin nodded.

"Although I don't understand these things, I haven't heard of a discovery that no one has ever made before. It can be successful the first time." Song Heng comforted, "So don't be depressed, such a magic medicine always needs several trials. Only twists and turns can be born."

"That's right, Ah Jin, your step by step is so complicated that most people can't even think of it. It's already very powerful." Little General Pei said.

The others also nodded, "Doctor Lu, don't worry, the battle hasn't started yet, just take your time."

"Just now, ordinary doctors can't do it. Doctor Lu is really Doctor Lu."

Lu Jin was a little embarrassed by the praises one by one, Song Heng laughed and said, "Okay, let's all go back, although it didn't work, but we still kept our mouths tightly shut, no one is allowed to speak, even the closest confidential."

"Yes, Doctor Lu, take a good rest."

After dinner, Lu Jin sat in the gazebo with her cheeks on her hands, looking at the stars in the sky.

In the starry sky without pollutants, those twinkling stars are particularly bright, large and small, covering the entire night, making people unable to help but immerse themselves in the splendor of the stars.

Although it is summer, there is no El Niño phenomenon, and the temperature at night is not too hot.

"I just ate a little for dinner, and I'm still thinking about the day's affairs." Song Heng came over with a plate of taro cakes and put them on the stone table. This is Lu Jin's favorite snack now. When I came back from the apprenticeship, I made some new tricks of my own, and the taste was even better.

Lu Jin took one, took a bite, and smiled slightly, "It's delicious."

Song Heng was relieved, and ate one too.

"I've been thinking, which step is wrong here? In theory, it all works." Lu Jin asked puzzled.

Song Heng naturally couldn't answer, so he could only listen to him.

"I went back and looked at the process again, and recalculated step by step, but I still don't know how to make changes. I know that these steps are a bit too simple, and there may be a loophole somewhere, but I can't think of it."

Song Heng said, "Then don't think about it for the time being, the more you dig into the horns, the more clueless you will be."

It is true to say so, but how can I control my thoughts?

Lu Jin remained silent, Song Heng raised his hand and gently brushed the corner of his mouth, wiping away the crumbs.

"You are just a person, not a god. How can you cover everything about Ah Jin? You are an excellent doctor, serious and responsible, with superb medical skills. In my eyes, you are already very good. Sometimes I wonder how you learned With this kind of ability, even if Miracle Doctor Hua is still alive, he might not be able to teach an apprentice like you, but looking around the world, no one can hold you back."

Lu Jin didn't expect Song Heng to start praising him in a serious manner, which made people feel hot and ashamed, but the corners of his mouth couldn't help but curl up, and his mood became joyful.

Song Heng looked at him, sneered in his heart, and continued, "Xiao Pei is right in what he said. Abducting you here is the most correct thing I have done in my life."

"I'm really so good." Lu Jin felt that he was not talking about himself.

Song Heng affirmed, "Naturally."

"Song Heng, do you really like me?"

"No, let's not separate in this life." Song Heng got up, walked in front of Lu Jin, bent down, and kissed him lightly on the brow, "So don't frown anymore. We will go to the city in two days. How about escaping the summer heat, I have a Zhuangzi, warm in winter and cool in summer, let’s go and relax together"

Lu Jin hummed lightly.

Having said that, Lu Jin was still a little unwilling. It was just dawn, so he got up and went to the simple laboratory.

No one had touched all the utensils since he left that day. He stood by the table, picked up the petri dishes of staphylococcus and looked at them one by one, carefully observing them.

But if there is no white circle, there is nothing, and it should not change after one more day.

"So where is the problem?" Lu Jin rested her chin and looked around the table one by one at all the utensils used in the refining process.

Not long after, Sun Bai and He Lan also came, and they were also worried about this place. After all, they had worked hard with Lu Jin for so long, but failed in the end.

But Lu Jin couldn't see anything, how could these two boys who seemed to understand half understand find out.

It was Uncle Fu who wandered over and asked, "Master Lu, do you still want the rotten fruit of Changqingmao? Zhuang Li is asking, if you want, someone will take it."

"Master, let's do it again, maybe we will succeed this time," He Lan suggested.

Lu Jin felt that it made sense, "Okay, if it still doesn't work, it means that there is a problem with my steps."

The second time I did it, I became more proficient. After a while, the Penicillium was collected, the culture medium was made, and it was grafted.

Staphylococcus does not need to be collected outside, and can directly use the colony of fifty pale yellow coccus culture medium as the strain.

Then there is a seven-day wait for the Penicillium to grow and produce penicillin.

During this period, Song Heng took Lu Jin to Zhuangzi to escape the summer heat and enjoy the coolness, and by the way, live the world of two people.

Seven days later, the two returned to the mansion, extracted and separated again to obtain a penicillin solution, and dropped it into a petri dish for Staphylococcus to see the final experimental results.

The steps are the same. Although Lu Jin feels that the result will not be different, she still holds a hope in her heart.

However, after all, a miracle did not happen to him.

The culture medium of Staphylococcus did not change.

"So it is inevitable. I have missed a key point, and I must find it out." He was not too disappointed this time, but made a decision to fight penicillin to the end.

Now that everything is safe and sound, he has plenty of time to do research.

But accidents always happen without warning, just like the fire.

No, it's not without warning, it's just that dull people don't realize it.
