Lianhai Center for Disease Control and Prevention, Laboratory.

The physical and chemical team is conducting a composition analysis of the sent energy stones.

In the emergency office, Gu Yanan put aside the luggage he brought back from the airport and sat at his desk to sort out the summary report of the experience of aiding Africa.

Lu Li and Wang Xiaoxiao were sent to the First People's Hospital to replace Xiao Chu and continue to work on the fat man's family of three.

Zhou Lao and Gao Fei are supervising the rat density survey in the county.

Only Gu Yanan was left in the office.

In the two months in Africa, she participated in the epidemic work day and night, and she was worried about Nan Hanfei, who had surgery in a foreign country, and often dreamed in the only rest time.

Back in Africa, the familiar tropical rainforest made the scenery in her dreams gradually clear, and the dreams were all related to the tropical rainforest, which also stimulated her to recall some memories of the past.

In one of the dreams, in a tropical rainforest with similar scenery, a man and a woman ran wildly in the rainforest holding hands, as if to avoid some danger, and suddenly, a group of black men with weapons rushed out, tied them together, and locked them in a small cabin in the forest.

At that time, this dream recurred many times, and Gu Yanan slowly realized that it might not be a dream, but a part of her vanished memory.

Now that he has just come back from abroad, he has encountered a radioactive energy stone incident, and he has not had time to rest and go back to the office to work, and now he has a terrible headache, Gu Yanan is supporting his head with his hand and preparing to take a two-minute nap.

As soon as I closed my eyes, the image of the rainforest appeared in my mind, the same cabin, the same black man with a weapon, and a man and a woman from before, both with their hands and feet tied, and someone pointed a gun at the man's head.

A gunshot rang out, and the woman flew up and blocked the man.

The bullet passed through the woman's chest and stayed in the man's head.

Gu Yanan woke up in a cold sweat.

She touched the scar on her chest, realizing that the vanished memories had finally returned.

At that time, Gu Yanan followed his supervisor to do a doctoral project abroad, and the topic was about the epidemic of rickettsial disease in the tropics.

As part of her research, she went to the tropical rainforests of Africa to collect specimens, and she met Nan Hanfei in a small village outside the local rainforest.

Nan Hanfei is also doing a doctoral project, and the two have similar research directions, so they have hired the same local guide, and they will accompany each other every time they enter the forest area.

Although Nan Hanfei grew up abroad, due to his parents, he spoke fluent Chinese, and he introduced his major and family background to her.

Nan Hanfei's parents, both naturalists, used his family's savings and charitable funds a few years ago to set up the Global Virus Prediction and Early Warning Network to monitor and warn of viral diseases that could be prevalent around the world.

The tropical rainforest is a natural breeding ground for all kinds of viruses, and Nan Hanfei's parents live here all year round, monitoring the transmission and flow of various viruses from animals to human society.

This profession is given a beautiful name - Virus Catcher.

Nan Hanfei inherited his father's business and also became a virus catcher.

The two talked about their career aspirations, and Nan Hanfei once laughed: "If there were extraterrestrial intelligent beings who wanted to compile an encyclopedia for the life of the earth, 27 of the 30 volumes would be about bacteria and viruses, and only a few would be about plants, fungi and animals, and humans would be just an interesting footnote." ”

Gu Yanan agrees with him, "Yes, in terms of numbers, bacteria and viruses are the rulers of this planet. ”

On a subsequent trip to the rainforest, the two encountered a local rebel force and were taken hostage.

After the gang learned Nan Hanfei's identity, they tried to extort ransom from him as a hostage.

In the process, the two escape, angering their kidnappers.

One of the ringleaders wanted to kill Nan Hanfei, and she flew forward to block the bullets.

The scars on her chest and back were left at that time, and the bruise in Nan Hanfei's brain should also be the sequelae of that time.

Did Nan Hanfei later change his career because of that accident?

Did he come back because of her?

But that doesn't matter anymore, the important thing is that he recovers.

She touched her mobile phone and sent a few messages to Nan Hanfei abroad, "The memory of Africa, I have remembered, are you okay?" ”

"I've never felt that my thoughts have weight, but this time my thoughts have overwhelmed me."

"The flowers bloom on the mo, and the thoughts are missing."

"Love you! Yanan. ”

Although there was no response to the previous message, she believed that Nan Hanfei could see it.

The office phone on the desk rang, Gu Yanan put down the phone, connected the landline, and the voice of Section Chief Li of the laboratory came from inside, "Director Gu, do you guess what ingredients were detected in the energy stone sent by the customs?" ”

"What radioactive elements?"

"Mainly uranium-238 and thorium-232, but also trace amounts of cesium-137, these power stones are uranium ores, more precisely ores containing a variety of radioactive materials."

The fat man who sold these power stones said before that these power stones were purchased from the rocks under a well-known volcano in country T, and the rock layers with radioactive substances often left behind after the eruption of the volcano, it seems that someone developed these rock layers and made them into power stones, but they all know that although these power stones have energy, they are all radioactive energy that can kill people, and people wearing these ores can not only not cure diseases, but also kill people.

Knowing the chemical composition of the second batch of power stones, and now I don't know whether the first batch of power stones contains radioactivity, I want to recover the first batch of power stones through the information provided by the fat man, test them, and track the health of people who have used these power stones.

In the afternoon of the same day.

Lu Li and Wang Xiaoxiao came back from the First People's Hospital, and handed them over to Gu Yanan with the sorted out flow information.

Wang Xiaoxiao was very emotional about the experience of the morning investigation, "This batch of energy stones is really harmful, fortunately it has not been widely circulated, that little girl has been diagnosed with severe aplastic anemia, and it will take a long time to treat it in the later stage, and the situation of his parents is not optimistic." ”

Lu Li: "Sister Yanan, these are the information on the sale of the first batch of energy stones, not complete, but he has tried his best to explain, many energy stones have changed hands, and the final whereabouts are difficult to find." ”

Gu Yanan thought about it, it is not a way to check it like this, not to mention the manpower, and in the end, it may not be possible to find out the whereabouts of all the energy stones.

"Lu Li, you first draft a notice, about the interception of a batch of radioactive energy stones by the customs, it is recommended that people who have purchased similar energy stones go to a professional institution to test for radioactivity, if there is a problem, report to the local disease control department, and we will go over to investigate."

"Okay, I'll write it right away."

Wang Xiaoxiao stared at the information he had just gotten back from the hospital and asked, "What about these people?" Do you still check? ”

"Check! This batch of gemstones has the greatest chance of having problems, so be sure to check! ”

Several members of the emergency team acted separately, and Zhou Lao and Gao Fei also returned from the county.

In order to facilitate the investigation, Gu Yanan sent a letter of assistance to the CDC across the country in the name of the Municipal Center for Disease Control and Prevention, so that the local CDC could assist in the investigation.
