In a short time, the narrow passage of Weijia Village was crowded with more than a dozen cattle from the villagers, and these cattle were fat and strong, and they were extremely sturdy.

But among the dozen cattle, there were three cattle, slumped to the ground, not in good spirits, lazily drooping their heads, chewing something in their mouths, a pair of dark eyes swept the crowd at will, and there was no interest in hanging down, leaving only a tail swaying from side to side in frustration.

Li Yuan walked over and squatted down and looked at the cow's abdomen, sure enough, it was a cow, dark red, and there were a few sores, all of which were pus, yellow, and very disgusting, it was indeed a cow suffering from smallpox.

Imperial Physician Xu also squatted down and said in surprise: "Daojun, this cow has moved over, but how can it be treated?" ”

As he spoke, he reached out to the pus part of the cow without any worries, pinched it, squeezed out the pus, put it between his nose and sniffed it, felt a little nauseous, and retched a few times.

"It's not difficult, this cow actually suffered from smallpox, but the immunity of cattle is much stronger than that of us humans, although the smallpox virus infected is the same, but after the cow has passed its own resistance and immunity, it has been able to produce a certain immunity, so smallpox is a mortal disease for people, but for cattle, it is rare to die......"

When the cowherd heard this, he laughed a few words and said: "Several nobles, the villain is called Wei San, my ancestors have been raising cattle since ancient times, and this kind of disease on cattle is not very rare, I remember that decades ago, there was a time, my father called him Huang Sezi disease, and the cow carried it in the past few days. ”

"It's unusual." Imperial Physician Xu praised a few words, after all, he is a medical family, not those foot doctors, so this disease on Niu has never been recorded in medical books.

For the dynasties, although cattle are an important tool for farming, it is strictly forbidden to slaughter them privately, but it does not mean that the Central Plains Dynasty lacks cattle, and who cares if there are a few dead?

"If there is an ulcer on our human body, if we don't treat it carefully, there will be pus. Remember the bacteria and viruses that the poor talk about? They come into contact with wounds through airborne transmission, and the human body acts as a shield to resist those pus, which are part of the bacteria, viruses, and antigens produced by the body. After the cow resists, the pus on the cow carries the antibodies of the cow and the smallpox virus, but unlike the previous smallpox virus, the smallpox virus at this time is basically eliminated, only a small part remains, and the pus is more antibodies against the smallpox virus. Li Yuan explained slowly.

Doctor Xu was dazed when he heard this, his two hands were restlessly under his clothes, and his old face was full of ravines... A little bit of shame!

There are a lot of nouns that I don't understand, but ...... It's amazing!

Obviously, the Emperor Taishang also fell asleep last night and was healed by the Taiqing sage, but why is he using it so easily now, it is so easy, could it be ...... Is it really a difference in aptitude?

Studying God and learning scum can't be compared, who is sadder than whom!

"What Daojun said... Although it is reasonable, it is not a trivial matter to cure the disease, as Daojun said that the snake venom is not poisonous in the abdomen, and the old man also found three roosters to do experiments, but today's smallpox plague also needs experiments, and... It has to be people! Imperial Doctor Xu said solemnly.

Li Yuan nodded, and did not refute, how to treat smallpox He only knew a little bit about how to treat smallpox, and if no one experimented, he would not dare to plant cowpox on people without authorization.

"The cure for smallpox is to plant cowpox, which is to apply pus from sick cows to human wounds. Do anyone dare to give it a try? ”

His eyes swept over the guards who were close to him for personal protection, each wearing Taoist robes, but they were also men who had been killed on the battlefield, and were sent by Li Shimin to protect him and the Taoist temple.

The closest to Li Yuan was the school captain Su Meng, who commanded the five hundred guards of the Taiyi Dao Palace, with swallow jaws and tiger eyes, and an eight-foot man. Half kneeling on the ground and shouted: "The last general is a native of Shanglin Village, Baili Township, Jingyang County, Guanzhong, if he dies this time, please let the last general return to his hometown and be buried with a certain one!" ”

With that, he landed on his knees and knocked on his head a few times. Then he drew the blade from the guard's scabbard and slashed it into his right arm.

Li Yuan nodded in agreement, and said to Su Meng: "If Captain Su successfully tests the medicine this time, it doesn't matter whether it is successful or not." I will thank you, Guanzhong fathers, and 200,000 displaced people will remember your kindness! ”

With a slash, blood gushed out from the dark arm, but Su Meng was not afraid or nervous, but shouted to the nearby guards: "Ma Er, bring the good wine you hid to a certain person, and a certain person will also learn from the second master this time." ”

Li Yuan's mouth twitched a few times, and the scratches didn't need to be so fierce, it was really a coward, and he waved his hand and hurriedly asked Imperial Doctor Xu to come forward to bandage the wound and test the medicine.

Ma Lao Er faced the vicious, wearing a Taoist robe, but when he heard Su Meng's words, he was like a wronged little daughter-in-law, twisting and pinching, but then under Su Meng's glare, he reluctantly uncovered the belt of his trousers, and rubbed out a small black bamboo tube, only three fingers thick, and handed it to Su Meng. scolded and said: "Captain Su, you can't cure my crime, this wine is a certain bottom, and I haven't drunk it at all when I am on duty on weekdays." ”

"How do you look like a." After Su Meng drank the wine in the bamboo tube, he shook his head not only to scold Ma Er, but also to scold Imperial Doctor Xu.

Doctor Xu Tai's medical skills are very good, and he is also very careful, he took out the pus from the little finger of the cow and smeared it on Su Meng's wound, and then bandaged it carefully with a linen, and the wound did not leak at all.

"Alright, just wait for the results of the experiment in a few days." Li Yuan said that he had done his best for the smallpox epidemic this time, and he could only hope that no more people from the Tang Dynasty would die.

But when he turned around, he found that hundreds of villagers surrounded him and Imperial Physician Xu in a semi-fan-shaped arc, and their eyes were hesitant, confused, and a little ... Expectation.

Li Yuan's eyes suddenly lit up, and he found a half-human-high earthen ridge around, stood on it, coughed dryly, and shouted: "Folks, do you know who Poor Dao is? Do you know who is sitting on the dragon chair in Chang'an? ”

The villagers shook their heads suspiciously, and then nodded, who else could be sitting on the dragon chair, the emperor!

"Ahem! The one who sat on the dragon chair was the turtle son of the poor road, and the poor road was the founding emperor of the Tang Dynasty and the emperor of the Tang Dynasty. ”

When the villagers heard this, they immediately fell to their knees, like the autumn wind blowing down the wheat field, and there was a big uproar, and there were tears in their eyes.

And the Wei Zi in the villagers knelt down and shouted: "This is Your Majesty, Your Majesty has never forgotten us and other people, when I was in Chang'an, if it wasn't for Your Majesty, a certain sister-in-law may have been sold, the Emperor Taishang is our benefactor, we can never forget!" “

"Emperor Taishang, we will never be ungrateful!" The villagers cheered up.

"Tsk, God assists!" Walking out of the aggrieved palace, Li Yuan felt the stirring in his heart for the first time, what a simple folks, he felt that he loved them to death.

It feels so good to be praised......
