Soon, the knight grabbed the two black dogs.

Take out a needle, stick it on the manic person, rub it slightly, pull out the needle and stick it into the dog's body.

Feng Xi waited quietly for the change of the dog.

In less than a moment, a black dog that had been captured began to agitate.

But fortunately, the dog's legs had been tied up beforehand, and now the dog was hanging in the air, roaring wildly.

A few minutes later, the dog died.

This phenomenon made Feng Xi slightly silent, and took out some black dog blood, comparing his blood with that of the manic man.

Because the experimental equipment was not perfect, Feng Xi had to use some soil methods to check, and in the end, it was found that there was something indistinguishable in the blood.

That thing was very contagious, like a mutated virus.

There were some conjectures in his heart, and Feng Xi mixed a piece of sick black-headed blood in clear water for the black dog who did not have a disease to drink.

This time, after waiting for a long time, the black dog is still fine, but his spirit is a little sluggish.

Seeing this, Feng Xi did many experiments again, and finally found that the only way to get sick was blood transmission and saliva transmission.

As long as you don't let those viruses come into direct contact with your blood, there's no problem.

But the point that he will lose his mind, Feng Xi has not discovered the principle, presumably only those bird-beak doctors know.

Thinking of Doctor Bird's Beak, Feng Xi was startled and looked around.

"Did those bird-beak doctors run away?"

At this moment, the king was a little confused, he did not know these things that the bird's beak doctor had done before he came, so he did not give an order to let the knight pay attention.

"No, according to some psychology, if all this was done by the bird-beaked doctors, then they definitely haven't left, they are planning to observe the results."

This is not unreasonable, if this disease has appeared before, it will definitely cause a sensation, after all, this contagion is so strong.

But there is not the slightest record in the history of this kingdom, which means that this virus is the first case.

And the Bird's Beak Doctor has always provided eternal water, according to the 6 major broken vows, the more terrifying and bloody the more likely it is to become a demon.

For this disease, Feng Xi prefers to believe that it is a coincidence, a coincidence created by those bird-beak doctors.

Otherwise, they wouldn't have been lurking in the castle for decades.

The king didn't know that Feng Xi had thought so much, and although he didn't know what psychology was, the bird-beak doctors he had heard from Feng Xi might still be here.

For a moment, the king looked around and felt that there were eyes secretly looking here, which made him shudder, as if there was a thief who wanted to take away his throne.

It made him very uneasy, especially in the dark corners, and the more he looked at it, the more frightened he became.

"Duke Leshbinkosen, watch out for those dark corners, and starting tomorrow, I will search the whole city, and I must find the man with the beak mask."

"Yes!"

Duke Lesbinkerson understood the gravity of the matter, and if it weren't too late, he would have wanted to set out for a search at once.

"King, there is no cure for this virus, it can only be prevented, I will tell some results later, and if I have the opportunity, I will spread the word throughout the country."

"Okay, Mr. Scholar, come with me."

Outside, the king didn't want to stay for a moment.

I'm afraid that something dirty will suddenly rush out of the dark corner, and then let him die here.

Just as the wind was about to leave, Duke Lesbinkersen asked:

"Mr. Scholar, what are you going to do with these things?"

"It's all burned, some suspects are locked up for 7 days, no symptoms are being released, and you will receive the detailed symptoms tomorrow."

"Yes, Mr. Scholar."

"Hmm."

After seeing the king and Feng Xi leave, Duke Leshbinkosen drew his silver sword and killed the two dogs cleanly.

"Throw them all in, and then add more fire to me, and if it can't be cleaned, then you will serve me as firewood."

"Understood!"

Among the many nobles, only Duke Leshbinkosen was a nobleman who personally participated in training all year round.

This also allowed him to practice the martial arts of a knight, and with the knowledge of the duke, his resourcefulness was not bad, but in the face of these invisible enemies.

Duke Lesbinkosen had no choice but to use the old method, to destroy in quantity.

The virus is an invisible enemy for Duke Lesbinkosen, he only knows that there are those corpses, but the silver sword can't kill it, but in the face of fire.

All beings are equal, and they will all be burned.

Among the simple king's residences.

Feng Xi recounted the experimental findings just now, and on the side, the Duke of Rochler wrote a book to record all this.

That's right, Duke Rochler, who was recording the crime, was called over by the king.

As one of the three dukes, the Duke of Rochler has the best recording ability and is the perfect choice for this record.

"Now, scholar, is there anything else besides what you said?"

Now the king really hopes that Feng Xi can say more and better, and as for Duke Rochler, who frequently moves his wrist next to him, he ignores it.

"King, it seems that I can only come to these conclusions from the present experiment, and besides, it is dawn now."

In the second half of the night, the king, the wind, and the Duke of Rochler stayed up all night to prevent and target these manic diseases.

Although it is not clear what caused the disease, rabies can be ruled out.

Because the disease worsens the temperature regulation in the infected person's body, it is likely to cause hyperthermia, killing the virus and the host at the same time.

It can also cause hypothermia, causing the limbs to stiffen, and then the brain to freeze to death.

He is also afraid of water and wind, and he is afraid of all the means by which the outside world changes the temperature.

Some changes in temperature will cause the temperature of the infected body to be disturbed, and the temperature will suddenly rise very high.

This conclusion was discovered by Feng Xi from the manic man who had been cut by the doctor and splashed with water.

The death of animals is also because the virus is too strong, and the temperature that the human body adapts to suddenly envelops the animals, making them very uncomfortable, resulting in death.

This disease had never been heard of before, and Feng Xi decided to find the bird's beak doctors, and only by knowing what they had given Hillington could he know about the causative agent.

"King, the beak doctor must be found, their very existence is very dangerous."

"I know the scholar, now Duke Lesbinkosen should be searching the territory."

"Then wait for news."

——

However, this time the search was destined to be fruitless.

Because, the bird-beaked doctors were watching this scene from the scene last night, but when the fire came up, they quietly left in the darkness of the night.

They are well aware that their identities will not be seen, so some of the escape methods are very skillful, and every time they enter an unfamiliar place, they will prepare several escape routes.

So the knights who were guarding the north and south gates did not notice them at all.

After all, these bird's beak doctors go underground.
