Night.

Fang Yuan turned on the lamp and looked through the file of the "Mutant Creature Wounding Case in Riverside Park" in his room, hoping to find some useful clues.

At three o'clock in the middle of the night, the door creaked open.

Fang Xiaozhu rubbed his eyes in a daze and walked in.

"Sleepwalking?" Fang Yuan stared back at her.

"It's not."

"Then why don't you sleep? It's three o'clock in the middle of the night. ”

"I dreamed that Xiong Ba was hanged, so pitiful, I reached out to save Xiong Ba, but I couldn't touch it, so I woke up."

Fang Xiaozhu walked to the table as he spoke, looked at the file on the table, and asked, "What are you looking at?" ”

"The file of Xiong Ba's case, I want to see what clues there are." Fang Yuan replied.

"I'll watch it too." Fang Xiaozhu sat on Fang Yuan's lap as he spoke.

Fang Yuan hurriedly blocked the photo on the information with his hand, and said solemnly: "It's too bloody, go back to sleep." ”

"I'm not afraid."

Fang Xiaozhu pushed Fang Yuan's hand away with his hand, and after seeing the bloodstain map, he said, "This is not very bloody." ”

This photo really doesn't show much blood.

Fang Yuan discovered this when he first saw this photo that day, but he didn't pay much attention to it.

Now that he suddenly heard Fang Xiaozhu say it, a flash of inspiration suddenly flashed in his mind.

"That's right. There isn't a lot of blood on this picture. But in the car that day, Zhou Xiaopeng said that the injured person had lost too much blood and had too low heme and needed to be hospitalized. ”

Fang Yuan's mind raced into thought.

With so little blood on the ground, how could he lose so much blood?

Upscale in an ambulance?

There was a doctor in the ambulance, and it was impossible to bleed so much in the car.

There's definitely something wrong with that.

……

The next day.

Fang Yuan rushed to the hospital and questioned the injured person who was hospitalized.

"Can you describe that day?"

The injured person was not in a good mood and said, "Didn't they all say that they were bitten by a panda?" I didn't expect something so cute to bite so hard. I just thought I was unlucky, and I didn't want to think about that night anymore. ”

"It doesn't have to be a panda bite, so please say it again."

"I don't want to say any more." The injured refused to cooperate.

"I'd advise you to say it again."

"You go, don't bother me again!"

Fang Yuan's eyes sank, he reached out and pinched the iron bed frame of the hospital bed, pinched it hard, and smiled at him: "Say it or not?" ”

When the injured man saw the bed frame that was pinched into twisted flowers, he swallowed and said, "Okay, comrade, what do you want to ask?" ”

The nurses around looked back, with strange expressions on their faces, and they wanted to speak but didn't dare to speak.

Fang Yuan smiled at them and said, "I'm sorry, I didn't control my emotions, I'll help you straighten it out later." ”

Next.

Fang Yuan began to ask, "Tell me how that thing bit you." ”

"It's to pounce on me from behind, to grab my back, to bite my shoulder, just here, here near my neck." The victim pointed his hand to the shoulder and neck, where the bandage was still tied.

"What was it like?"

"It hurts, it hurts to death, how else can I feel?"

"How long has it been biting? How long does it take for someone to come to your rescue? Fang Yuan continued to ask.

"It's hard to say, anyway, when I felt bitten, it was longer than a century, and I thought I was going to die." The injured recalled.

"Does it only bite you in this place? No other actions? Such as tearing, shaking, and the like. Fang Yuan asked again.

The injured man frowned and shook his head slowly, and replied, "No, it will bite me and I won't be able to move." ”

Fang Yuan felt a little strange.

Generally speaking, wild beasts such as lions, tigers, and bears, if they want to kill their prey, will shake their heads and tear them after biting, tearing the wound, which will make the prey bleed faster.

Fang Yuan went to the doctor who performed the first aid that night and asked about the situation: "How much blood did this injured person lose that night?" ”

"The injured person lost a lot of blood, more than 2,000, almost 3,000 milliliters." The doctor replied.

"I don't know much about blood volume, can you briefly explain what the concept of blood loss is two or three thousand milliliters?" Fang Yuan asked again.

"Two thousand five hundred milliliters, which is almost half the blood volume of the human body. At this level of blood loss, even lying down, the brain will be deprived of oxygen, leading to shock. The wounded man was very dangerous that night, and if he had been too late, he would have died. The doctor explained simply.

Fang Yuan took out the photo of the blood stains at the scene and asked, "Doctor, do you look at this photo, it looks like a trace of two thousand milliliters of blood?" ”

The doctor took a look at it and said, "How is it possible, this is a maximum of two or three hundred milliliters of blood." ”

"Then it's not right, this picture is the blood stain left on the ground when the injured person was injured, if the blood stain is only two or three hundred milliliters of blood. Could it be that the injured person lost blood in the ambulance? ”

"That's impossible, if the injured person can shed 2,000 milliliters of blood in the ambulance, then the doctor in the car can directly fire him." The doctor said with great certainty.

Fang Yuan looked at the video in the ambulance again, and could confirm that the injured person did not shed much blood in the car at that time.

There was not much blood shed at the scene.

There wasn't much blood in the ambulance either.

The wounded lost two or three thousand milliliters of blood.

Where did this blood go?

Fang Yuan had actually thought of one possibility, and the only one.

Blood was flowing into the stomach of the wounding monster.

After the mutant creature bit the wounded, it did not tear, but rather bited.

What are you doing?

The obvious answer is to suck blood.

It's a blood-sucking creature.

Although pandas can also eat meat, their staple food is bamboo, which does not suck blood.

What sucks blood?

The first thing that comes to mind for most people is definitely vampire bats.

However, in fact, most bats do not suck blood, and bats mostly feed on insects.

Of course, vampire bats do exist in the world.

However, of the more than 900 species of bats in the world, only one bat sucks blood.

And this bat is small and not ferocious.

Because the nutrition of blood is not high, it cannot grow much by sucking blood.

Of course, the possibility of mutated vampire bats cannot be ruled out.

However, according to Lu Xiuwen's account, the creature that committed the murder that day ran away, and if it was a mutated vampire bat, it should fly away.

Therefore, Fang Yuan could basically be sure that it was not the vampire bat that committed the murder.

In addition to vampire bats, those who like to suck blood are vampires.

Of course, there is no such thing as a vampire.

However, it is possible that the Awoken has awakened a vampire-like ability.

Fang Yuan found a new clue and immediately returned to the Super Management Bureau to find Zhou Xiaopeng.

"I've found a new clue, the mutant creature that committed the murder sucked blood, and sucked two or three thousand milliliters of the man's blood. You can help me check what mutated creatures like to suck blood. ”

"How can I check this? You go to Professor Lu. He is a biologist. Zhou Xiaopeng said.

Fang Yuan thought about it, felt that it was the same, and said, "Then you help me call him and ask him where he is." ”
