According to the records in the history books, the detection of the wind and ground motion instrument is still relatively accurate. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 infoEven if you can't get to the area, you can still detect it as long as there is ground movement.

However, Yu Nianniang accurately told Chi Langyi that the area of ground movement was in Xincheng, Gansu, and that there would also be ground movement in Longxi.

Not to mention this era, even in modern times, no one dares to be so sure.

Chi Langyi held the pen in his hand and looked at Yu Nianniang with a serious face: "Have you figured it out?" Isn't that a small matter? ”

Yu Nianniang nodded: "It's clear." "If it was just divination or other methods, she wouldn't be so sure, but given the special nature of her ability, tracing the past and predicting the future, she must be very confident.

"And ......" Yu Nianniang looked back at Chi Langyi with a serious face: "If the court does not deal with the post-disaster casualties and health prevention and control in a timely manner as I said, there will be more trouble." ”

"What's the trouble?" Chi Langyi frowned.

"Plague!" Yu Nianniang said lightly.

Chi Langyi's pupils shrank.

"At this time, it is the beginning of spring, everything is recovering, the weather is warmer, people and animals often die after the ground moves, the corpses of people and animals are quickly eroded, and there are some sewage, garbage and other dirty water and dirt that no one manages, which will also form a source of infection, at this time there will be a large number of flies, but also parasitic lice. The most important thing is the water problem......" Yu Nianniang told Chi Langyi all the work she remembered after the modern earthquake, swept her eyes, and the disbelieving expressions on the faces of the eleventh and others, she said: "Don't think I'm alarmist, if these things really happen, it's too late, prevention is more important than cure." ”

Then Yu Nianniang hooked the corners of her mouth and looked at Chi Langyi: "Great opportunity, do you want to do a business?" ”

Chi Langyi paused to lift the pen, and turned his head to look at her: "What business?" ”

"After the earth moves, it is easy to cause plagues, mainly because of water pollution, to put it bluntly, rainwater pollution, which can lead to viruses and bacteria. Moreover, in the case of a shortage of food, food, and water, it is easy to break out intestinal diseases, so it is necessary to dispose of excrement. It is also necessary to have clean water, food, personal and environmental hygiene, and flies. This requires a good job of disinfection. At the same time, there are also requirements for the location of the camping...... "After all, the conditions in modern and ancient times are very different, Yu Nianniang just said the important part of the attention, and the specific way to do it is the affairs of the court."

Whether it is food, drinking water, or washing water, it must be clean and unpolluted. Water can be transported from other places, and places near the mountains can be taken from high places in the mountains.

Flies, mosquitoes, etc., can be expelled by fumigation.

But......

"Miss Yu, what do you say have to do with business?" Eleven doubtful words.

Yu Nianniang glanced at Chi Langyi, who was lying on the desk, and the master's brain was easy to use.

"Isn't that a business opportunity?" Yu Nianniang looked at Eleven.

Eleven looked confused.

Yu Nianniang sighed: "So, you can prepare some related medicinal materials." Even if you don't sell it, someone else will sell it. It is better to prepare enough medicine in advance and sell it cheaper, that is, to make money and have a reputation. ”

Eleven's face was stunned, and then he hesitated: "What if those medicinal materials can't be used?" ”

Yu Nianniang pursed her lips: "Of course, it's best not to use it." I've told you everything I know, whether the thing will be used or not, whether anyone will use it, then I don't know. ”

As soon as these words came out, several people present frowned.

Although the atmosphere of the court is very positive, the subordinate officials from all over the country have always had the consciousness of the emperor far away, and they often think about themselves first before they manage the people.

Yu Nianniang's method doesn't seem to be much, but it is troublesome to do, I am afraid that some of the officials below will try to save trouble, and the consequences will be unimaginable.

Di Sha looked at Chi Langyi: "Childe, your subordinates must remind the prince when they see this, otherwise there will really be a plague like what Miss Yu said, and the consequences will be very serious." "The first is the carbonization of living beings; The second is that the crown prince is in charge of the country for the first time, and if it is not handled in time, it will greatly reduce his status in the hearts of the people, the court, and the emperor!

Chi Langyi knew this, so he wrote all Yu Nianniang's words in the letter, and finally asked Yu Nianniang: "Then how to do this disinfection?" ”

"The food and drink were clean, and the dishes were boiled in boiling water. As for the corpse, it should be disposed of as soon as possible, and it is best to choose cremation, so that the source of infection will be cut clean......"

Everyone was stunned, and even Chi Langyi had a shocked expression.

Yu Nianniang knew that these ancients couldn't accept it, so she had to say: "I know that it is difficult for the people to accept, if it can't be cremated, then it must be buried as soon as possible." Otherwise, as soon as the body decomposes, the bacteria will quickly spread...... You can buy quicklime in large quantities and sprinkle it on some polluted water sources, excrement, and soil to prevent bacteria from growing......"

In fact, quicklime disinfection has been available for a long time, but it is not used much.

After the letter was written, Chi Langyi immediately flew a pigeon to return to the capital, and at the same time repeatedly reminded the prince that if he wanted to prevent the plague, he must follow Yu Nianniang's method.

He was worried that the carrier pigeons would not arrive, so he sent another eleven fast horses to rush back to the capital day and night.

When the prince received the letter, he was very shocked, and he didn't care to ask the emperor for instructions first, so he immediately sent someone to hurry to Gansu with the holy decree.

The people who sent the holy decree galloped all the way, non-stop, day and night, without sleep, in order to send the holy decree to Gansu as soon as possible, they only ate one meal a day, also on horseback.

When the horse is tired, he immediately changes horses when he goes to a place, and when he is tired, he changes people. All the way non-stop. Ten horses were killed, and each messenger was almost paralyzed from exhaustion, with a layer of skin on both legs and legs worn off, and when he took off his pants, there was a large patch of blood. In the end, it finally took less than half a month to arrive in Gansu.

*

Three days after the Xincheng land, Yu Nianniang arrived in Luoyang, divination and flying pigeons, and it took a total of one and a half days for the prince to make a decision.

After sending the holy decree away, the crown prince hurriedly explained the situation to the emperor again, and in the emperor's reply, he was very satisfied with the eldest prince's treatment. The prince breathed a sigh of relief in his heart.

Natural disasters can't be avoided, but man-made disasters can. The crown prince knew that this was the time to test himself, and if he did well, then the throne would be secure.

Don't think that he can sit back and relax if he is crowned prince, it is not without princes who have been abolished because of mistakes in previous dynasties.

So, the prince wrote another letter to Yu Nianniang and Chi Langyi: "Since we already know the approximate location of the ground movement, we must think of ways to control the disaster, minimize the loss, and do a good job of prevention in advance......"

But Gansu is too far from Luoyang.

On the second day after sending the letter to the capital, Yu Nianniang pushed another hexagram, this time she saw clearly and heard more accurately.

The ground movement in Longxi turned out to be seven days later.
