As soon as he entered the city, Yang Xiuting smelled a smell like rotting meat.

The streets of Wan'an County have not been cleaned for a long time, and the surface of the bluestone bricks on the ground has been covered with moss. The houses are also dilapidated. The low and dilapidated houses on the street also look dim and damp because they have not been taken care of for a long time, and the wall skin has long been peeled off, and the walls are uneven.

The streets of the entire county were empty, showing a dilapidated scene.

Suddenly, Yang Xiuting heard the cry of a little girl, and he searched for the sound and found that the cry came from a dilapidated hut. So he prepared to go and have a look in the house. Just as he was about to enter the room, Li Langzhong stopped him.

"Wait a minute, Young Master Yang." Immediately, Li Langzhong took out a veil from his arms, "Young Master Yang, please put the veil on, so as not to be infected by the plague." ”

After putting on the veil, Yang Xiuting entered the house, and he saw that there were only a few tattered old wooden beds in the house. The kitchen was small, damp, and smelled musty. In the corner was a little girl, her face was all black, she must have been smoked by firewood when she was using the stove, and there were tears in the corners of her eyes that had not been wiped off.

"Girl, what's wrong with you." Yang Xiuting asked.

The little girl trembled with fear, and she shrank back.

Yang Xiuting saw her fear, and went over to pick her up and put her in his arms, "Don't be afraid, girl, tell my brother what happened." ”

The little girl then said that her parents had died of the plague, and she was the only one left in the family. She probably hadn't eaten for several days, and she was hungry and looked pitiful.

So Yang Xiuting took out some dry food and money from the burden and gave it to the little girl, enough for the little girl to last until the plague was over. And before leaving, Li Langzhong also gave the little girl a veil and told her not to go out as much as possible, and to put the veil on if she had to go out.

After saying that, the two of them left.

After Li Langzhong led Yang Xiuting around Wan'an County, after understanding the situation. They set out for the village, and before leaving, they told the soldiers guarding the city gate: "When His Royal Highness the Prince and the Fifth Prince come, let them go to the village as well." In order to find the source of the plague, it is necessary to start exploring the place where the plague existed in the first place.

The next day, they also arrived in Wan'an County.

They found that Wan'an County was no longer as prosperous as their mother described in the letter, and Wan'an County was in ruins at this time.

The soldiers told them that Yang Xiuting had gone to the village to check the root cause of the plague, but Xiao Jue decided that he would not be in the mood to manage the plague after burying his mother first, so he asked the five princes to go to the village to assist them first.

Because of the plague, it is not appropriate to hold too grand a funeral. And Princess Yu didn't like to be noisy before her death, and Xiao Jue didn't want to disturb the cleanliness behind her mother, so Xiao Jue built a tomb for Princess Yu in a secluded mountain forest next to Wan'an County. This mountain forest and water are clear and beautiful, Xiao Jue thought that his mother should like this place.

Looking at his mother's coffin, Xiao Jue's eyes revealed a sad look again, Sheng Zi'an found that he didn't speak after he found out, but just held Xiao Jue's hand tightly, what Xiao Jue needed at this time was companionship.

When the construction of the tomb was completed, King Yu also rushed over. He hadn't seen his son for many years, although he didn't like Princess Yu, but Xiao Jue was his own flesh and blood after all, and it was impossible to say that he didn't miss him.

"Jedigo." King Yu saw Xiao Jue.

After hearing the voice, Xiao Jue was stunned, as if he had lost the ability to command his own actions, and stood there motionless like a log, and after a long while, he turned his head to King Yu and said, "Father."

Xiao Jue's father and son met for the first time in so many years, and they were not as excited as ordinary people, and they quietly felt that the air next to them was frozen, and the two didn't say a word.

"Hello father, I'm Sheng Zi'an." Sheng Zi'an saluted King Yu, and this embarrassing scene was finally broken.

Only then did King Yu notice Sheng Zi'an on the side, he saw that Sheng Zi'an's complexion was as white as jade, his skin was better than snow, his skin was delicate and delicate, and his goose egg face looked beautiful and moving. King Yu is still satisfied in his heart, and this woman can be regarded as worthy of Xiao Jue.

"Father, mother passed away, please mourn." Xiao Jue said that he knew that his father would not be sad, but the face work that should be done still had to be done.

"Hmm." King Yu didn't say much. Xiao Jue also expected this result, his father has always been so indifferent to his mother since he was a child.

Xiao Jue ignored King Yu's indifference and continued: "Since you have come here, let's go to the mourning hall to see my mother." ”

King Yu arrived at the mourning hall and looked at the coffin in front of him, thinking in his heart, Princess Yu has been working hard for herself and Xiao Jue all her life, if it weren't for someone else in her heart, she should have become a very good husband and wife with Princess Yu, and King Yu's heart immediately welled up with a trace of guilt. Soon he shook his head to sober himself up, and the only person he loved in his heart was that person.

"Father came all the way, he must be tired, it must be tired, it is better to rest early." Xiao Jue said.

"No need, the border is complicated, I can't stay here longer, since I have seen your mother, I will leave for home." King Yu did not have a trace of nostalgia on his face, and was indifferent as if the deceased person was not his wife.

Xiao never expected that his father would be so indifferent that he couldn't even wait for the time of his mother's burial, and then the anger in his heart surged into his heart. Since King Yu was so anxious to go back, Xiao Jue naturally didn't keep him anymore, "Since that's the case, then father be careful all the way." ”

After saying that, King Yu was ready to set off.

"Qi Yu Shizi, if his subordinates have to be repaid." A soldier hurried in.

"Tell me, why are you in such a hurry?"

"This—" The soldier looked at King Yu in hesitation.

"But it doesn't hurt to say it."

"Just now, the soldiers from the village came to spread the word that the fifth prince was unfortunately infected with the plague!"

"What? The Five Princes are also here? He also contracted the plague? Before Xiao Jue could speak, King Yu's voice came first, and he acted as if his own son had been infected with the plague.

"Isn't my father still leaving? The son has to deal with things, and he can't care about sending his father out of the city. Xiao definitely didn't have any hope for King Yu, and now he just wanted King Yu to go back quickly, so that he could see that he was upset.

"Are you leaving for your father? My father thinks it's extremely inappropriate to go back now, so I'd better wait for your mother to be buried and go back for my father! After all, husband and wife. "That's not what King Yu thinks in his heart, this fifth prince is the son of the woman that King Yu has always loved in his heart.

Aiwu and Wu, in King Yu's heart, the five princes are even more important than Xiao Jue, and now that the five princes are infected with the plague, how can he leave with confidence. I must wait for the fifth prince to recover before leaving, otherwise I will feel uneasy.

Xiao Jue thought that his father knew that he was guilty and planned to stay, so he agreed.

"Then father go and rest." King Yu stayed.

After King Yu left, Xiao Jue had a headache and said: "The fifth prince was infected with the plague, how can this be good, if something really happens, how can I explain it to the emperor."

"It's okay husband, you forgot that I am a medicine man, put my blood into medicine, and the five princes should not have any major incidents." Sheng Zi'an comforted.

"How can this work, treat a fifth prince, and so many people are also infected with the plague, the husband will not let Zi'an do this." Xiao Jue frowned, and said with a solemn face. Sheng Zi'an has shed a lot of blood for herself, and her body has become very weak. So this plague, he won't let Sheng Zi'an continue to do this.

The discussion was fruitless, and Xiao Jue and Sheng Zi'an also rested early.

Because there were still a few days before the day of Princess Yu's burial, Xiao Xiao left for the village the next morning.

"Zi'an, you're here." When Yang Xiuting saw Sheng Zi'an, he felt that his fatigue for many days had been swept away. After not seeing Sheng Zi'an for many days, Yang Xiuting's longing in his heart had already overflowed, but he knew that his thoughts were wrong, so he had been suppressing his feelings.

Then Yang Xiuting told them in detail about what he had discovered in the village for so many days, and that he was helpless against this plague even under his tutelage of medical saints, which made Yang Xiuting feel very frustrated.

When Xiao Jue saw Li Langzhong, he thanked Li Langzhong first, and took a thousand taels of silver tickets to give to Li Langzhong. Li Langzhong felt guilty that he failed to cure Princess Yu, and it was his responsibility to treat the disease and save people, so he did not receive the money given by Xiao Jie. Li Langzhong also told Sheng Zi'an that he and Yang Xiuting had not found the source of the plague until now, and his most important discovery now was that the plague might be transmitted through the air, and gave everyone a veil he made.

Sheng Zi'an couldn't help but praise Li Langzhong's medical skills when he saw the veil, this kind of modern thing was actually made by Li Langzhong, although it looked a little simpler, but it still played a little role.

Listening to Li Langzhong's words, Sheng Zi'an had a little idea in his heart, "I once saw a precedent for a similar disease in an ancient book, this is not like a simple plague, as long as you don't come into contact with the patient, you won't be infected." This type of airborne infection is called a viral infection. People infected with the plague may be contaminated with viruses when they talk, touch and use things, and healthy people breathe these viruses or I think the veil is too thin to fully resist the invasion of the virus,"

Naturally, the medical skills of the ancients were not strong enough to detect the spread of the virus, so this is the reason why they have not found the source of the plague for a long time.

"Virus? Never heard of it. There is also such a medical book, the old man has never seen it, I wonder if the princess can tell the old man that this is the ancient book? ”

"Zi'an, I've never heard you talk about it." Yang Xiuting also said.

They both wondered what kind of book would record such a mysterious thing.
