Ask Sword

An autumn rain blew, and the weather in Chang'an became cold and humid. Li Wei, who was staying in the academy, complained about the anti-tide in the dormitory, so he asked Li Ang for a talisman and stuck it on the quilt.

The sudden change of weather also caused many coughing patients to appear in Chang'an City. Li Ang was a little worried about this, so he went to the ward to observe and found that the symptoms of the patients were wind-cold, stuffy nose, runny nose, itchy throat, that is, a cold .

The doctors in the ward are not surprised by this, it's just a mere wind and cold, compared with the horrors of malaria, phlegm, and tuberculosis, it's nothing worth mentioning, and it's not clear why Li Ang pays so much attention to it.

"Cold is not scary, just be afraid of influenza"

Li Ang said silently in his heart.

In the memory of the other world, the great flu in the early 20th century directly infected one-third of the world's population and killed at least 20 million people.

The secondary disasters caused by manpower shortage are even more incalculable.

Cities with high population density and high circulation will always have various strange symptoms. With the two to three million people in Chang'an City, it is not very strange for Li Ang to have any symptoms.

He couldn't explain to the doctors in the ward what a virus is, so he had to use his influence to make the ward clean and isolate, and prepare enough medicines.

After he went back, he published an article in the academic journal, demonstrating the relationship between wind-cold and other diseases and wearing a mask, and proved that wearing a mask can significantly reduce the probability of suffering from wind-cold.

I hope this will allow more Chang'an citizens, especially those with wind-cold symptoms, to wear masks.

‘Tsk, why do other people only need to enjoy the joy of pretending to be slapped when they travel through time, while I have to worry about various diseases. '

Li Ang sat on the seat, rubbing his temples to relieve the pressure.

After nearly a year of research, the sanitation in Chang'an City has improved a lot compared to before. At least every household bought soap and soap, washed their hands frequently, did not drink unboiled water, and took the initiative to kill mosquitoes and rats.

Since Li Ang published a paper on dissecting mice, giving detailed examples of diseases that mice may cause,

The people in Chang'an City hated rats even more, and they worked harder to exterminate rats. .

It made Li Ang dream that there was a fat-headed and big-eared mouse being hung from the street lamp, howling and screaming, "Shushu, I really have to reopen."

Weird dream.

"Sunrise!"

Yang Yu hurried over from the door of the classroom, sat down on the stool with a bang, lowered his voice and said excitedly, "Did you hear that?"

Li Ang was a little speechless: "What did you hear?"

"The mission of Haotian Daomen."

Yang Yu patted the table, and said in a high-spirited tone: "For the first time in fifty years, Mount Taihao sent an official mission to Chang'an. Now it has entered Xijing, and it will arrive in Chang'an after a while."

Li Ang pouted, "So?"

"This is a big deal."

Yang Yu said excitedly: "The mission is led by Cardinal Xinxiu, one of the four Cardinals Haotian. My grandfather heard about it and ate an extra bowl for dinner. Others who heard the news have already started preparing flowers in advance And the red carpet."

"Is it that exaggerated?"

Li Ang couldn't help being speechless.

Taihao Mountain and the Academy have never dealt with it very well. The last time they sent people over was to celebrate the birthday of the Holy Empress—and it didn’t take long for the Holy Empress to fall, and the late Emperor took over.

At that time, Haotian Daomen felt that the time had come, and sent a mission to Chang'an, claiming to preside over the enthronement ceremony of the late emperor, but was directly dismissed by the academy.

The enthronement of the kings of the Southern Zhou Dynasty, Xijing and other countries was presided over by the cardinal priests of Haotian Daomen. There is also divine power above the imperial power. If the cardinal priests are not satisfied, in theory, they even have the right to change the emperor.

Only the State of Yu, which has a school palace, is not subject to this control.

As a result, the relationship between the two parties has turned cold, and there has been no communication for fifty years.

However, the conflict between Mount Taihao and the Academy did not affect the devotion of the people of Yu State to Haotian. Every household still wears Haotian bells and Haotian bells, and often goes to temples to burn incense, pray, and pray for blessings.

Li Ang himself was not very pious, and he was completely indifferent to the so-called visitors from Taihao Mountain. And Yang Yu, who came from a pious family, was looking forward to it very much, chatting non-stop beside him.

When a cardinal or priest walks in the world, both sides of the road must be crowded with pious people, laying a red carpet for him and sprinkled flowers.

When the cardinals and priests come to Chang'an, they will definitely take the Suzaku Avenue. At that time, I don't know how many fanatical believers will go there a few days in advance to set up tents, lay down on the floor, and sleep there sooner or later, just to be close to each other when the mission passes by. The cardinal's distance.

'. How does it sound, the one who is coming is not the cardinal priest, but the new Apple mobile phone? '

Li Ang complained silently in his heart, and it's hard to say that feudal superstition is not advisable - Haotian Bell and Haotian Bell can really have an effect on aliens, suppressing evil spirits to a certain extent.

'Forget it, as long as it doesn't affect my study and practice. '

Li Ang shook his head, ignored Yang Yu's self-talk, and focused on the book.

Tread Tread.

The sound of footsteps came from far to near, and Miao Zhengqing, the supervisor of the palace, walked into the classroom, and Xi Yangyu came with him.

Xuegong Jiancheng is an official position set up by the imperial court. He is responsible for communicating information with the Xuegong. He usually only shows up on important occasions and will not interfere with normal classes.

"cough."

Xi Yangyu coughed lightly, and the conversation in the classroom immediately quieted down.

Miao Zhengqing walked to the front of the stage, cleared his throat, and said loudly: "I think all the students have heard the news more or less. In a month or two, the mission of Haotian Daomen will come to Chang'an City.

One of the reasons they came here this time was to re-establish contact with the State of Yu.

The second is to conduct academic exchanges with the academy. "

"Um?"

Li Ang raised his eyebrows, academic exchange?

Is there any place where Haotian Daomen and Xuegong can exchange academic knowledge?

You must know that the contradiction between the two parties has a long history. Taoism believes that everything is created by Haotian, and it has its own perfect and eternal laws.

The Academy develops Neo Confucianism, observes celestial phenomena, and concludes that the orbits of stars will change constantly, and some stars will even appear and disappear out of thin air.

There are also some scholars who study philosophy and ask questions. If Haotian loves the world, why does he create all kinds of eerie and strange monsters, and set up an endless sea full of dangers to hinder the world from exploring.

Even the senior Su Zi, because Haotian Daomen repeatedly criticized him, directly uttered the wild words of "the changes of the sky are not to be feared, the ancestors are not lawful, and human words are not enough to be sympathetic", which made the Taoist sect very angry.

One of the purposes of the Academy is to explore the laws of nature, and it has nothing in common with the Taoist who wants to maintain the majesty of Haotian, let alone academic exchanges.

Sure enough, Miao Zhengqing immediately added: "The scope of communication is not limited to poetry, calligraphy and painting, rhythm, talent, etc.

There are also competitive exchanges in practice.

Students of all ages can participate.

In addition, students of the same age from Xijing, Southern Zhou, Turkic and other countries will also come to Chang'an to participate in the conference.

As for the specific matters, we will wait for the mission to arrive and give further notice. "
