Only then did Shen Liufeng know what was in that big leather bag.

It was the blood of the wolf.

If the living creature is killed immediately, the blood will immediately stagnate and coagulate, and it is impossible to take out a large amount of blood. Xue Yan was able to take out so much wolf blood because he slit the wolf's neck, but he didn't let it die immediately, but held it down when it was dying, until he had enough of his blood, before taking it out. The wolf was killed.

A dying beast is the most ferocious.

It wasn't until he got closer that Shen Liufeng could see clearly that Xue Yan's robe was also torn a few times. From the cracks in his sleeves, one could see the deep wounds on his flesh.

Shen Liufeng looked at it and felt his eyes hurt.

The genius doctor stepped forward, weighed the skin in his hand, and said, "Huh, so many? Enough is enough."

He said before that he asked Xue Yan to get more blood because he knew that the blood of dead things was hard to get, so he wanted him to kill two more wolves in case the blood was not enough. But didn't expect that this man was so ruthless and ruthless that he could actually take blood from a living wolf.

Xue Yan hummed, her voice scarily hoarse.

"I'm going to pack up the things I'm going to use," said the genius doctor. "I can't make it at night. You help me remove the wolf bone first. I will use it. When the sky is clear, we will leave."

Xue Yan responded without raising his head. He turned around and dragged the wolf outside the door a little bit. Using the light from the open door, he pulled a stool and sat down beside the wolf's body.

The genius doctor went into the house by himself and packed up the medicinal materials and utensils.

Shen Liufeng was bored sitting alone in the room, so he simply dragged a chair and sat opposite Xue Yan.

Xue Yan had already pulled out his dagger and started to dismember the wolf's body. Although his face was already showing signs of exhaustion, his swordsmanship was clean and neat.

Seeing Shen Liufeng sitting over, Xue Yan's subordinates paused without lifting his eyelids, and said, "Go back, don't get in the way."

Shen Liufeng had to move the small stool back awkwardly.

"Is this wolf so big?" he asked without words.

Xue Yan hummed: "Head wolf."

Shen Liufeng was shocked.

"Good guy, you killed the alpha wolf?" he said.

Xue Yan put the peeled wolf skin aside.

"It's big," he said. "Blood."

This tone is understated, like picking radishes when shopping for vegetables.

Shen Liufeng swallowed his saliva and set his eyes on his arm again.

There were obvious scars scratched by the wolf's sharp claws. The wound was deep, and the flesh at the wound turned out slightly.

Shen Liufeng said: "You have an injury, don't you need to let the genius doctor bandage it before you leave?"

Xue Yan looked up at Shen Liufeng.

"You talk so much all the time?" he said.

Shen Liufeng snorted.

"Either stay away or keep your mouth shut." Xue Yan retracted his gaze, his tone was light, but he carried a frightening sense of oppression. "It gave me a headache."

He hadn't slept for several days in a row, and now he's holding on to his energy, all because of Jun Huailang.

But that didn't prevent him from being exhausted all over his body, and he didn't feel much pain. He only felt that his temples were throbbing, making him very dizzy.

Shen Liufeng did not dare to speak.

Xue Yan lowered his eyes and went on to do the task at hand.

Then, he stopped again.

He looked up at Shen Liufeng.

Under the dim light, there was a warm fire in his eyes, but it didn't warm his amber eyes at all. Even Shen Liufeng, who had thick nerves, noticed the badness in his eyes.

He...he didn't speak just now?

Hearing Xue Yan speak.

"Don't tell Jun Huailang a word about my injury," he said.

Shen Liufeng:  …

He didn't quite understand what Xue Yan meant by saying this, but since he said it, Shen Liufeng nodded in agreement.

Xue Yan withdrew his gaze and went to dismember the wolf.

Shen Liufeng breathed a sigh of relief and couldn't help but murmur in his heart.

King Guangling is really strange. He is extremely cruel to the people around him and himself. How could he be so careful when he arrived at Huailang?

But that's right, Huailang is so lovable, he must not even be able to resist the hard-hearted King Guangling.

——

When it was slightly dawn, Xue Yan had already piled the clean wolf bones in the magic doctor's room.

The genius doctor handed the blood bag and the packed package to Xue Yan.

"Bring one?" Xue Yan weighed the skin bag, a little puzzled.

The doctor nodded.

"Whether it is useful or not, you will know when you arrive in Jinling," he said.

The three of them rode their horses all the way out of the mountain.

When they got to the bottom of the mountain, the magistrate of Yangzhou was already waiting at the mountain pass and prepared a carriage for the divine doctor. There were six carriages in that carriage, all of which were good horses, and they ran no slower than horses.

Shen Liufeng, who had been knocked to pieces by the horse for a long time, quickly got into the carriage with the genius doctor.

The three of them rushed back all the way and arrived at Jinling at noon.

After the carriage entered the city, it rushed all the way to the Governor's Mansion without stopping.

Now the imperial physicians brought by Xue Yan are all in the governor's mansion and placed in several courtyards. When they came back, the doctors were arguing hotly, but without exception, none of them had found the cause.

It's very strange that this epidemic is a fever on the surface, but it can't be cured.

Although they argued fiercely, none of them actually had an idea.

When Xue Yan came, he saw them arguing together like headless flies.

Seeing the scene in front of him, Xue Yan's face suddenly sank.

For a while, everyone was silent, and no one dared to speak.

"This king brought you to Jinling just to make you quarrel?" Xue Yan's voice was hoarse and cold, making everyone shudder.

They serve in Chang'an and the imperial city all the year round. Who doesn't know that His Royal Highness King Guangling is not only extremely favored, but also especially violent?

The genius doctor glanced at them and saw the famous doctors huddled together like a row of quails.

The magician burst out laughing.

"Don't attack them." He said gracefully. "Aren't you trying to save people? Take me to see the patient first - is there one in this yard?"

Xue Yan's eyes froze.

He hummed and said to Jinbao, who was waiting beside him, "Lead the way."

Jin Bao didn't dare to delay at all, and hurriedly led the genius doctor to the place where the cases were placed in the small hospital.

The two patients placed in the small yard were the first to have a fever, and they have not been cured until now, relying on medicinal materials to hang their lives.

Xue Yan followed the genius doctor into the yard.

The genius doctor paused, turned around and asked, "What are you doing here, aren't you afraid of the disease?"

Xue Yan only said: "I'll take a look with you."

Naturally, he couldn't see anything, but the doctor saw that he was in a hurry.

He smiled and didn't stop him any more, and made a gesture of invitation to Xue Yan.

The two people in this hospital are very ill. When they entered, there was no one else in the room, only the two people on the bed in the room, with their eyes closed tightly, their faces flushed with sickness, they were already breathing more and less.

Xue Yan frowned.

The genius doctor saw his deteriorating expression and could roughly feel it. Xue Yan frowned, definitely not worried about these two people.

As for why...

Presumably in this cold-hearted King Guangling, there must be someone who is extremely important to him, who also contracted this disease, so that he can feel so empathetic and rush to Yangzhou as if he was dying. Dig yourself out of the mountain.

The word "love" is amazing. The genius doctor has been in the arena for many years and has seen it a lot.

He smiled without saying a word, walked to the bed and went to see the doctor.

After looking, hearing, and inquiring, he took out the finger blood from one of the patients and examined it carefully. After a while, the genius doctor smiled lightly and said, "Sure enough, I guessed right."

With that said, he said to Jin Bao, who was standing beside him, "Go find an official in charge."

Jinbao hurried out and brought an official in.

That official was the chief official who followed Jun Huailang to repair the embankment before.

"I ask you, when did this epidemic happen?" he asked.

The official in charge hurriedly said: "About ten days ago, there was the first case."

"What happened in the place where the disease broke out before that?" he asked again.

The official thought: "The place where the epidemic broke out was the prison in Jinling where prisoners were held. A few days before that, there was a big accident on the dam, which injured some workers. His Royal Highness made the decision and imprisoned all those workers. already."

The doctor laughed.

"That makes sense." He looked at Xue Yan. "The wolf blood I asked you to collect is also useful."

Several people in the room looked at him.

I saw him find a pen and paper, and write the prescription smoothly. While writing, he also pulled out the medicinal materials from the package he was carrying.

"When oranges grow in Huainan, oranges are oranges, and when oranges grow in Huaibei, oranges are oranges. Have you heard of this saying, Your Highness?" he said.

Xue Yan nodded.

Seeing the genius doctor, he continued: "Lingnan is full of miasmas, mountains and lakes, especially in the southwest. The terrain there is narrow and the diet is different from the Central Plains. In addition, the people in the mountains always have their own food, while outsiders eat it. Something that cannot be done. Over time, the people there, especially the bandits who have lived in the mountains for a long time, have some toxins in their blood, and they can resist it themselves, but it is different for outsiders. "

Xue Yan frowned: "You mean, the workers in Jinling mixed in with the bandits in the southwest?"

The southwestern border is the vassal area of ​​the King of Yunnan.

With a stroke of his pen, the genius doctor finished writing the prescription.

"These, you have to check it yourself." He put the prescription on the table and said. "Send someone to boil the medicine. Use wolf blood as the medicine. You don't need much, just take the medicine. If I guessed correctly, one medicine will be effective."

Xue Yan looked at Jinbao.

Jinbao hurriedly sighed, trotted all the way with the prescription in hand, and went out to ask someone to boil the medicine.

"Send a copy to the deceased ovary in a while." Xue Yan said.

There was no need for Xue Yan to mention this at all, Jin Bao responded repeatedly and ran out.

The genius doctor sat down leisurely.

"You don't have to blame the imperial physicians," he said. "They stay in Chang'an all day, what incurable diseases have they seen? The old man travels the world, and naturally he has more knowledge than them."

Xue Yan responded and got up.

"The prince you mentioned is the one you saved that day, right?" The genius doctor looked at him with a playful look in his eyes.

Xue Yan looked back at him calmly, without any signs of dodging: "Yes."

The doctor laughed.

Xue Yan said: "I will arrange for someone to find you a place to live, you can do it yourself."

Saying that, he turned around and went out.

What are you in such a hurry to do? It must be guarding that person.

The divine doctor kindly reminded: "You don't have to wait. If you still want your life, you might as well go to sleep first."

As a doctor, he can see at a glance that this person's energy has long been overdrawn, and he is now hanging with a breath of air.

Xue Yan's footsteps did not stop.

"I'm going to watch him wake up," he said.
