The man's voice is slow and magnetic, and his breath is burning like fire.

Spray it on your ears like an ant nibbling.

Jiang Fuyue subconsciously shrunk her neck and murmured, "if you want to add sin, what can I do?"

Xie Dingyuan sighed and stared, "of course it's none of your business. I blame you for your beauty."

Jiang Fuyue reddened her cheeks and suddenly closed her eyes: "I'm sleepy."

"Well, have a good sleep and go out tomorrow."

"What if I can't get out?"

"I'll go out." his steady voice had a calming magic.

"OK."

……

Scenic area, hall.

The uniformed police lined up in two lines, accompanied by police dogs.

All the special police of linhuaibei district were dispatched and the search work was carried out quickly at the command.

It soon disappeared into the darkness.

Civilian search and rescue teams are also in place. Although the former lacks the momentum of uniformity, the tools and equipment at hand are all showing their professionalism.

"Here we go, brothers --"

"Yes!"

The three teams diverged in the southwest, northwest and due west directions.

"I'm a good boy. What's the origin of the missing two? Even the special police team sent out collectively!"

"I heard it was Professor Xie."

"Which Professor Xie?"

"Which other Professor Xie do you say? Nova virus, C99 vaccine."

"God! It's him! Don't have an accident. Our country can't lack him. Half of the country is here, whether it's biological defense or chemical warfare!"

"Isn't it? Once something happens to this, the whole China will have to be shocked."

"We all work hard to find people as soon as possible, which can be regarded as making contributions to the country and the people."

"Then hurry!"

"Go, go..."

Let's go together.

Ling Qingzhou stood in front of the window and had a panoramic view of the scene.

Yi Hansheng: "don't worry, with Xie Dingyuan, she will be fine."

After a long time, I heard him say, "where are the three small ones?"

"Followed behind the team to help."

Ling Qingzhou frowned: "nonsense!"

Yi Hansheng sneered, "it's easy to say. Go and stop one? Can you stop it?"

“……”

"As the saying goes, it's better to block than to drain. It's better to let them leave than to let them escape. Maybe they can really help."

"I'm afraid I didn't help. I added a lot."

Yi Hansheng turned his eyes: "your son is much more useful than you think. Don't think you are capable. You can carry things. They are not bad."

……

After midnight, the temperature dropped again and again.

Jiang Fuyue leaned against the man's chest, curled up slowly in a comfortable sleeping position, and finally huddled herself into a ball.

The originally shallow sleeping man suddenly opened his eyes and found that the girl in his arms was shaking.

His eyes were suddenly cold: "Jiang Fuyue?"

"..." no response.

"Jiang Fuyue!" he continued.

Still not.

"Jiang Fuyue! Can you hear me? Wake up!"

Finally, "... Hmm? What's the matter?"

"Open your eyes and look at me."

Jiang Fuyue struggled to open her eyelids, but her pupils were scattered: "you, call me?"

"You're shaking."

"It doesn't matter. I'm just... A little cold."

The man subconsciously held her tighter and suddenly said, "you're having a fever!"

"... no wonder you are soft and weak."

"Don't sleep yet." Xie Dingyuan got up.

As soon as Jiang Fuyue grabbed his waist, it was completely a subconscious action, like grasping a hot water bag to be robbed in winter, or the only ice stick in his hand in the hot summer. It was more appropriate to use conditional reflection——

"What are you doing?"

The man's eyes showed helplessness: "I'm not leaving. I just want to check your legs."

If it is a high fever caused by inflammation of the wound, it will be in trouble.

"Why, don't you want me?"

Jiang Fuyue angrily withdrew her hand and argued, "I can't bear the temperature on you."

"Oh, that's why I can't bear it."

"You are so cheeky," he said weakly, and the lethality was about zero.

Xie Dingyuan smiled and his eyes showed joy: "I think your duplicity is better than usual."

Jiang Fuyue: "..." listen, is this what serious people should say?

The professor's design collapsed.

Xie Dingyuan got up and went straight to the girl's feet. Due to the limited roll up of her trouser legs, she couldn't see her whole left leg.

He was afraid of other wounds. In a moment of silence, he suddenly said, "can you take off your pants?"

Jiang Fuyue was so dizzy that she almost fell asleep again. When she heard this sentence, she immediately disappeared her pajamas and woke up——

"What are you talking about?!"

"Take off your pants to check the condition of the whole leg. Now you can only see the lower leg, so..."

Jiang Fuyue gritted her teeth: "do you have to take it off?"

Xie Dingyuan: "yes."

"... then take it off."

The man was surprised: "me?"

"Yes, I am now. Do you think I can take off my pants by myself?"

Xie Dingyuan: "... Oh."

Ten minutes later, the man carefully peeled the girl's left leg out of the trouser barrel.

The skin color is snow-white, the lines are symmetrical, and no fat can be seen.

It would be a perfect work of art if it weren't for the purple knees and red swollen ankles.

The tentacle warms up, delicate and soft.

Xie Dingyuan carefully checked every place and determined that there was no obvious trauma. Only then did he quietly breathe a sigh of relief.

Jiang Fuyue raised her head and said, "how about it?"

"It's not an inflammation of the wound, it's just an ordinary fever."

Jiang Fuyue also breathed a sigh of relief. She was very clear about the consequences of wound inflammation in this environment.

Seriously, it's not impossible to burn a fool and amputate something.

"Then help me put on my pants."

"... oh."

The man put on his pants for her without complaint, moving light and light, and avoiding the injury as much as possible.

When he lifted it up, he accidentally touched his thigh. The greasy touch made the man's heart palpitate.

It was cold and more than ten degrees below zero, but he stubbornly held back a hot sweat.

"... OK."

"Thank you."

“……”

Jiang Fuyue hugged her arms and trembled slightly because of the cold. Seeing that the man was still in place, like a brick, she couldn't help but urge: "you lie back!"

Xie Dingyuan was shocked.

Jiang Fuyue's eyes showed doubts: "

What's he doing?

Finally, he adjusted his breathing and suppressed the surging heat in his body. Xie Dingyuan got up, turned back to his original position and lay down beside Jiang Fuyue.

The girl automatically stuck it to his arms.

When the warmth hit, she sighed with satisfaction.

Then

The man had just relaxed and his body was stiff again.

Although there was no trauma, the fever continued.

Jiang Fuyue felt her eyelids drooping uncontrollably. Xie Dingyuan kept talking in her ear: "don't sleep, shall we continue to ask questions?"

“……”

"Jiang Fuyue?!"

“……”

"You open your eyes."

"Xie Dingyuan, you are noisy."

The man breathed a sigh of relief: "can you straighten out the hair on the coconut?"

"What?"

Xie Dingyuan: "imagine a sphere with hair on the surface. Can you comb all the hair flat without leaving a pinch of hair like a chicken comb or a twist like hair? [1]"

Jiang Fuyue blinked, "... No."

"Why?"

"I guess."

"You guessed right."

Jiang Fuyue: "why can't you comb all the hairs? It has something to do with... Topology?"

"HMM. hairy ball theory, have you heard of it?"

"Browell?"

"HMM." Xie Dingyuan nodded, "in mathematical language, on the surface of a sphere,

There can be no continuous unit vector field. When it is extended to higher dimensional space, it means that for any even dimensional sphere, the continuous unit vector field does not exist. [1]

Jiang Fuyue: "if applied to meteorology, because the wind speed and direction on the earth's surface are continuous, according to the hairball theorem, there will always be a place with wind speed of 0 on the earth."

Xie Dingyuan: "therefore, cyclones and eye of the wind are inevitable."
