More and more people are flocking to the hospital, diagnosed with the disease, and sent to the observation center.

There are more and more patients, and Gu Li is busy all day long, and she has no time to eat or sleep. But even so, the disease is spreading rapidly at an uncontrollable rate.

After heavy rains, pathogenic bacteria spread in all directions with the flow of water, infiltrate the soil, and contaminate objects, but if you are not careful, you can contract the disease.

The entire Changning City was panicked, and rumors were spreading. The cure rate of this disease is indeed not high, so everyone in the city is afraid of contracting the disease and wants to leave.

From the point of view of preventing the spread of the disease, it is natural that people should not be allowed to go out of the city at this time. The government has long issued a ban on anyone leaving the city at will.

But such a ban is bound to offend many people. There are already rumors among the people that this epidemic is because of the tyranny of the emperor, which angered the heavens, so God sent this disaster.

The emperor was worried day and night, and he could not ignore the will of the people, and he was already planning to issue an edict against himself.

Gu Li has been in the observation courtyard for the past few days, and has not left even a step. However, no matter how hard she tries, there are still many people who fail to save her and leave this world forever.

The people in front of him went in and out, coming and going, and Gu Lijue's heart was numb. Too much grief, too much helplessness, little by little, again and again, as if invisibly, paralyzed her nerves.

Suddenly there was a sigh behind him.

Gu Li looked back and saw that Mei Zhangyuan had arrived next to her at some point.

"If I had adopted your advice earlier, it wouldn't have caused the predicament we are in now." Mei Zhangyuan sighed.

If the body that had been buried had been dug up and cremated and re-buried, it would not have been the way it is now. But at that time, no matter who it was, they felt that this move was too anti-ethical and moral, and they would not accept it, let alone adopt it.

No one expected that maintaining ethics and morality would have to pay such a heavy price.

Gu Li showed a bitter smile on his face and did not reply.

"Mei Zhangyuan, I'm going to leave tonight and go to the laboratory to have a look. I'll bother you to arrange my work again. Gu Li said to him.

"There you go." Mei Zhangyuan nodded.

Mei Zhangyuan is over fifty years old, but like Gu Li, he has been sleepless during this time and sticks to this place.

In the evening, Gu Li and Mei Zhiyan went out of the city together and went to the hot spring courtyard.

In the petri dish in the laboratory, you can immediately know whether the penicillin prepared this time has an effect.

The two put on isolation gowns and entered the laboratory, Mei Zhiyan opened the cover, and Gu Li came to record.

Mei Zhiyan lifted the lid of the first petri dish and observed the situation inside.

"One, no change."

Gu Li's heart sank, and she also raised her eyes to look over there.

In the first petri dish, there was a large patch of golden staphylococci scattered around, and there were no small white spots in it.

She had high hopes for this experiment, so it seemed that it might not work.

"It's okay, there are nineteen more." Gu Li smiled and said.

The petri dish has not yet been fully uncovered, and it is too early to say that the experiment failed.

Mei Zhiyan's eyes above the mask also diffused a little smile, and he nodded, uncovering the lid of the second petri dish.

"Number two, no change."

"Hmm." Gu Li responded softly and recorded it.

"Three, no change."

"Four, no change."

……

"Eleven, no change."

Gu Li's heart sank little by little, could it be that this experiment was going to fail again?

The last time it failed, it was because there was no sterile experimental environment. But this time, with the help of Yan Qing, she already has a sterile environment, isn't it okay?

If she fails again this time, then she really doesn't know what to do.

Perhaps, there is such a thing as penicillin, which will not appear in this era at all. She wants to make the impossible possible here, which is her wishful thinking.

At the moment when Gu Li lost his mind, Mei Zhiyan reached out and opened the next petri dish.

"Twelve—"

His voice pulled Gu Li's thoughts back.

Gu Li held a pen in his hand and hung it on the paper, waiting for him to continue.

It's nothing more than those three words: no change.

However, Mei Zhiyan did not speak again.

Gu Li was suspicious in her heart, and was about to ask him what was wrong, when she suddenly heard him say, "Doctor Gu, come and take a look." ”

Gu Li put down the pen and took a closer look, and saw that in the No. 12 petri dish, in the middle of a large piece of golden yellow, there was a small light yellow circle.

It's not a small white dot, it's light yellow, which doesn't mean that the experiment was successful, so Mei Zhiyan hesitated.

Seeing this light yellow dot, Gu Li was also stunned, and then said, "Continue to uncover it." ”

"Hmm." Mei Zhizhi said in response, and lifted the lid of the No. 13 petri dish again.

Inside this petri dish, there is still a small light yellow dot, which is a little lighter than the small dot in the No. 12 petri dish.

"Go on." Gu Li said again.

Mei Zhiyan continued to lift the lid, and uncovered four in a row.

When he opened the seventeenth petri dish, the hand holding the lid trembled.

Gu Li also saw it, and her heartbeat suddenly missed a beat.

I saw that in this petri dish, in the middle of a large golden colony, there was a small white dot. The boundaries are clear and clearly visible.

Gu Li's eyes were staring at the little white dot tightly, with mixed feelings and mixed feelings in her heart, and she didn't know what to say or how to react.

She actually went to ask Mei Zhiyan: "This, this should be considered a success, right?" ”

Mei Zhiyan was surprised and delighted, and replied in a slightly trembling voice: "It should be, it should be." ”

Before the words fell, the two tacitly looked at each other and laughed.

"Yes, it worked! Little white dot, the experiment was successful! Gu Li reacted at this time, and said incoherently in surprise.

There were still three petri dishes left, and Gu Li opened the lid all at once, and saw that inside each of them, there was a cute little white spot that was clearly visible.

Looking at it, two lines of tears suddenly fell from her eyes.

She succeeded, really succeeded, and in this era, found a way to make penicillin, and succeeded in making it.

In the future, these penicillins will be used in clinical surgeries and will save thousands of lives.

Gu Li cried with joy, as if she saw hope and the dawn of the future.

Mei Zhiyan was also excited, and asked Gu Li, "With this medicine, can it really treat infections?" ”

"Really!" Gu Li had tears in her eyes and laughed loudly.

Mei Zhiyan nodded solemnly, and her eyes also sparkled.

They are all healers, and they have the mission of saving lives and helping the wounded, so at this moment they can understand how excited and uplifting each other's hearts really are.
