The days of the safe zone passed day by day, and the black flu finally spread in the survivor base in Yancheng. Walking on the road, you can see people covering their mouths and noses with scarves and collars everywhere, and you can also hear coughing everywhere.

The fatality rate of this disease is about 3% according to the statistics of the T-City Research Institute. This data is not low in the flu, which makes the already understaffed Yancheng survivor base even worse.

The power of black flu for ordinary people is like a small cold, it is not very serious, and the fatality rate is also very low, but for the supernatural, the fatality rate of the disease is as high as more than 40%, as if it is a virus that specializes in restraining the supernatural.

The ability is precious, and the tasks that can be performed cannot be stopped, let alone the slightest sloppiness. Before the vaccine was developed, there were more paraphiles dying of illness in the Yancheng survivor base than those who died because of the mission itself, and the bodies of the paraphiles were carried out for cremation every day.

Even Zhou Chenghua, Xiao Miao and others are in danger of themselves, but Minister Zhou has a tense face as before, so that people can't see any fear.

At this time, Tan Yue's other task was completed.

【Ding Dong!】 Task 9: Raise a school of turtle fish, reward: 4000 energy points. 】

Tan Yue raised her eyebrows and said, "System, why do you give so much today?" ”

The system twisted: [Isn't this a flu recently...... The system makes it convenient for the host to save those patients......]

"I thought you'd just post the task."

[Ah, thank you for the good ideas provided by the host!] Ding dong! Released side quest: Use the Turtle Fish to quell the flu at the Yancheng Survivor Base. Reward: A pair of Reiki-powered gliders. 】

Every time the "......" system releases a temporary mission, the rewards are bizarre.

"Let's go, then." Tan Yue said.

"Dawn! Let's go! ”

"Meow~"

……

Tan Yue told Gu Zhuoran the news of the turtle fish, so the two went to the manor together.

The manor has been expanded, and the alien warriors that could be seen here some time ago are gone, leaving only a small team of people who protect the safety of the manor.

Tan Yue came straight to the small lake, who expected that the pearl turtle fish would swim too fast to catch it.

Suddenly, her sleeve was pulled off.

"Qin ...... Qin Heng? ”

The little dragon pointed to the lake with its wings and barked again.

"You mean, you can help catch the fish?"

Xiaolong volunteered to scream.

Tan Yue put the little dragon in his hand on the ground, only to see it fly into the air, hovering above the lake, staring at the bottom of the lake with sharp eyes, and suddenly a swoop swept across the lake, and when it flew up again, the dragon claw caught a four-eyed, six-legged pearl turtle fish.

Tan Yue caught the big fish jumping around, and the little dragon screamed and flew above the lake again.

The fish fell into her hand, squirmed for a moment, and spit out something stained with slime from her mouth - Tan Yue looked closely, it was a pearl!

Gu Zhuoran observed with interest on the side, and said from time to time: "Magical." ”

"Dean Gu," she asked, "Do you know how many Aliens there are in the Yancheng base?" ”

Gu Zhuoran thought for a moment and said, "If I remember correctly, there are more than two thousand four thousand. What's wrong? ”

Tan Yue was ashamed, the number of supernatural people in his own base still needed to be known from the population of T City.

She was a little embarrassed: "It is true that the pearl turtle fish can be immune to black flu if eaten, but we can't raise enough fish to eat more than 2,000 people in a short period of time." ”

"It's a problem." Gu Zhuoran also thought about it.

Tan Yue suddenly thought of something, opened the card page of the system mall, and rummaged through it.

Sure enough, there is more than one kind of creature that can resist the plague. There is also a kind of spirit animal, called the green ploughing bird, which is recorded in the "Classic of Mountains and Seas" as "there is a bird, its shape is like a magpie, the green body and white beak, the white eyes and white tail, the name is called green ploughing, it can resist the epidemic, and its song is self-calling".

Tan Yue had a conjecture, she asked the system: "The system, the principle of the green cultivator bird to prevent the epidemic, can it be understood as emitting a special kind of radiation, which can stop the spread of infectious diseases within the radiation range?" ”

[The host guessed correctly, the special phenomenon about green cultivators recorded in the "Classic of Mountains and Seas" is indeed a kind of radiation. 】

"If this kind of radiation can be simulated and replicated, won't the source of the epidemic be cut off?"

[The host is right, based on the current research progress of the Institute, it is already possible to simulate a specific broadcast for a long time.] This line of thinking works. 】

Tan Yue felt a burst of excitement, and said tentatively to Gu Zhuoran: "If I have a radiation source whose radiation can stop the spread of the epidemic, is there a way for the research institute to broadcast this radiation?" ”

Gu Zhuoran's eyes lit up: "What do you mean?" Do you have this radiation source? ”

Gu Zhuoran became excited and began to say some terms that Tan Yue didn't understand.

Tan Yue was overwhelmed by his sudden enthusiasm, and decided to exchange the cards first.

It cost her 4,999 energy points to exchange for cards, and Tan Yue stroked the gold-edged SSR card, feeling that the whole card was saying "use me quickly, use me quickly".

She resisted the urge and decided to go back to the base and use the card again. She must first find out whether the research institute has the ability to broadcast largely, otherwise it is very dangerous to rashly show her hole cards.

I don't know if Gu Zhuoran saw something, he said to Tan Yue: "If you want to take a look at the research results of the institute in this area, of course we can show you." ”

……

An hour later, the Yancheng Underground Base Research Institute.

In the center of the boxy room was a huge piece of ore, and Gu Zhuoran introduced beside her: "This is a kind of ore that has been dug deep in the mine in the past two years, which can simulate the various radiation it absorbs. We use it with a device to amplify radiation, and it can do what you said. ”

"How many such ores are there?"

"A lot, enough."

"Can you show us your hole cards now?" Gu Zhuoran and Dean Xiao had obvious irrepressible joy in their eyes.

Tan Yue nodded, his spiritual power covered the card, and suddenly a blue and white bird appeared on the desk.

It is a very beautiful bird, with white feathers around its eyes, white tail feathers, and a gorgeous cyan color covering its body parts, which makes people feel that it is a strange color that cannot be blended with paint.

Tan Yue said to the green cultivator in a heartfelt voice: "Can you use your ability against that piece of ore?" ”

The green cultivator bird cried, flew above the ore, and then slowly landed and lay on it.

It's like hatching eggs.

Tan Yue: "......" feels weird.

The inside of the colorless ore lit up with a cyan glow, and after a while, the whole body glowed, and there was a bird lying on it, which looked strange and gorgeous in the laboratory.
