Hygiene has always been a major issue closely related to health.

Datang people also pay more attention to hygiene, for example, the Qingming Canal is river water, but Chang'an people only use it for cleaning, sprinkling and sweeping. And all that is drunk is well water.

Well water is safer and more hygienic than river water, which is the most simple concept.

"The accumulation of decay gradually polluted the canal water, and the canal water soaked through the ground...... Here we want to talk about the source of well water, the source of well water is divided into two types, one is diving, what is diving? It is the water source that is nearby and is soaked in, as is the case with the well here, and its water source comes from the water of the Qingming Channel......"

Yu Chi didn't interject and felt uncomfortable, Xun Yu suddenly realized, "Sir, the rotten water will soak into the well, and then the person who drinks it will get sick. ”

Jia Ping'an has always wanted to clean up his problem, and Li Yuanying's reaction was the most positive, and he slapped it.

"This king teaches you a lesson."

Li Yuanying said it rightly, and when he saw Wei Chi Xunyu's hideous face, he couldn't help but regret it a little.

This stupid black boy won't be ruthless to this king in secret.

Jia Ping'an nodded, looking at how a certain student was stunned, but he secretly hated in his heart, and he was ready to turn around and clean up this guy.

"How so? Can...... How to prove it? Some officials questioned it.

Today, Jia Ping'an said that he wanted to unravel the root cause of the people's ease of getting sick, and Li Zhicai sent someone. But Jia Ping'an opened his mouth to something they didn't understand, and they were confused.

"If the water in the well comes from a ditch, why does it taste different?"

Some of the wells in Chang'an are bitter, and some are sweet.

"Because the water passes through different places!"

A group of fools, Jia Ping'an fooled casually.

The key is......

"Invited Gong Qin."

Qin Ping is here.

"May I ask Gong Qin, how is the water from the well at home before?"

"Sweet." Qin Ping said: "When the old man was still young, he was greedy for cold in summer, so he directly drank well water, which was sweet and unforgettable. But then it gradually changed, the taste was weird, and in recent years, it has become more and more unpalatable. ”

"The rotten stuff is soaking in." Jia Ping'an knew that hearing was false, "There are two methods, one of which is not to drink raw water, this is an iron law." Second, disinfection! ”

"Disinfection?"

Jia Ping'an nodded, "Everyone, please take a look." ”

"Sprinkle lime!"

The water in the well was hollowed out, and the lime was sprinkled from above, and someone on the side took a look, but Li Yuanying, who sprinkled the lime, moved a little bigger, and actually raised the lime.

"Someone's eyes!"

The official covered his eyes and screamed.

"Get water! There's water here! ”

Wang Zhongliang asked someone to help him over, and prepared to wash his eyes with the water from the well he had dug earlier.

"If you want him to be blind, wash it with water." Jia Ping'an looked indifferent.

"What do you mean?" Wang Zhongliang turned to look at him.

"Quicklime is highly corrosive, and it will react strongly when it encounters water and burn ......"

This group of pampered guys has never made quicklime at all.

Jia Ping'an made a handful of quicklime and threw it into a bowl of water.

Laugh at!

Offended.

Wang Zhongliang softened, "What about that?" ”

"Got oil."

Doesn't it smell good with vegetable oil?

After washing his eyes with vegetable oil, the official screamed, "I must be blind, blind!" ”

"No, I can't be blind." Jia Ping'an looked at his eyes, but they were corroded, but not serious, just raise them for a while.

"Go home and raise it."

Someone helped the official to go back, and Wang Zhongliang asked, "Why is this?" ”

"Said ......" Jia Ping'an wanted to say that you don't understand, but still explained, "Quicklime will react when it encounters water, releasing a large amount of heat ......"

The bowl of water was a little hot.

"And why does it disinfect?" Wang Zhongliang felt that this was indescribable.

Jia Ping'an deeply misses those years of study, "Because many germs have a substance called protein, quicklime can not only heat up when exposed to water, but also generate strong alkali ...... Heat cannot sterilize, but strong alkali can inactivate the proteins of those germs, thus completing the sterilization. ”

Everyone was stunned.

Jia Ping'an smiled bitterly: "It's not that I don't want to explain, but it is estimated that I can't finish explaining it for three days and three nights." ”

"I'm willing to listen to it for three days and three nights." One of the officials seemed interested.

"But you have to learn from scratch."

"Yes, I'm studious."

"It's a new school." Jia Ping'an smiled, "You have to learn from scratch...... That's a whole body of knowledge, are you sure you're ready? ”

"System?"

It's a strange word.

"Yes, for example, the protein mentioned earlier, the germs mentioned by such and such a person, and how quicklime produces strong alkalis."

It's a huge system, and the officials feel terrible just thinking about it.

"Is this the new learning?"

"Yes!"

Quicklime goes down to disinfect and no more water is taken later.

"Is quicklime poisonous when mixed with water?"

"In the end, another substance is formed, and the well water can be washed several times."

Three days later......

The well, which had been disinfected several times and cleaned several times, was filled with water again.

"The taste has changed!"

Wang Zhongliang tasted it and said in surprise: "Although it still has a strange taste, it is a little sweet." ”

"Boil and drink."

Jia Ping'an had the well water boiled, and then tea, and a group of people drank it by the well.

“…… Jia Ping'an drank the most. ”

Wang Zhongliang also drank a lot, "He just drinks soup like a meal, and he also makes people add salt." ”

"It seems that there is such knowledge in the new school." Li Zhi was not interested in Guozijian Zhuxue, but he was quite curious about Xinxue.

Jia Ping'an said that everything has a root, and the water in the well comes from the underground water, and the groundwater cannot be born out of thin air, it comes from the soaking of rain, river water, and seawater. Why is some well water sweet and some bitter? One is to look at the water source, and the other is to look at the way of soaking. ”

"Those dirt and rocks?" Li Zhi figured this out, "I remember someone said back then that when you look at the clear stream in the southwest, you can feel bitter when you drink it, and then you will die. Later, someone went up and found rotting leaves and brightly colored stone mounds at the source......"

It's easy to figure it out.

Wang Zhongliang felt that the emperor was really smart, "Your Majesty is wise. ”

"There are a lot of wells in the palace, and Jia Ping'an's method is used to get quicklime to disinfect."

The emperor is always the one who is most afraid of death, and Li Zhi hates that he can't disinfect his residence with quicklime.

As a result, a disinfection operation was launched in the palace, and the quicklime was thrown in, and some palace people shouted: "What a big fish, turned over the white belly." ”

Wu Mei was far away, and Zhang Tianxia behind her said: "After Wu Yangbo was disinfected, someone bought a house immediately, and others are still waiting......"

"Your Majesty asked quicklime to disinfect the well in the palace, which is to help." Wu Mei smiled, "They have made money, you have to remember Your Majesty's goodness." ”

When the news came that the palace was disinfecting the wells with quicklime, the houses immediately became fragrant and sweet.

"They rushed to buy it, and a few relatives came to the house, talking about their friendship for many years, and Aya said that Aweng could make decisions, so they went to see Aweng, and they were scolded by Aweng......"

Yu Chi Xunyu looked very proud.

Wei Chigong has gone back to cultivation since the last time he bubbled.

"All of my family was sold." Li Jingye was very melancholy, "I asked Ah Weng to stay in two houses, and in the future, a good gold house was hidden, and the result was ......"

He pulled back his shirt and turned around, seeing two fuchsia marks on his back.

"Ah Weng has two sticks in his hand." Li Jingye sighed: "But it doesn't hurt at all, I feel that Ah Weng is afraid that he is old, brother, you said last time that the older a man is, the worse he is, why don't you find a few female prostitutes to try Ah Weng?" ”

"The Guild of England discounts your legs." Wei Chi Xunyu found a sense of IQ superiority in Li Jingye.

"What's the matter, it's not pleasing to the eye?" Young people are like this, they have to do something wrong with a word.

Wei Chi Xunyu sneered: "I'm afraid you won't succeed? ”

Li Jingye got up and said, "Go out." ”

"Get out, get out."

The two went out, and Li Yuanying asked, "Mr. doesn't care?" ”

"If you don't die, you can do it." Li Jingye and Wei Chi Xunyu both belong to that kind of excess energy, and it is better to fight.

Woohoo!

Outside, Wang Lao Er took Xu Xiaoyu to watch the battle and analyzed him.

"Li Langjun has more strength, and Wei Chi Langjun has more changes."

"And who can win?"

Wang Lao Er pretended to be an old driver, "Of course it's Li Langjun." ”

Before the words fell, Li Jingye punched Yu Chi Xunyu's shoulder.

"Stop!"

Wei Chi Xunyu squatted on the ground, covered his shoulders and scolded: "Where did you get so much strength? ”

"Born." Li Jingye looked invincible and lonely, and sighed.

"Who can be a match for so-and-so? Who? ”

Jia Ping'an, who was inside, couldn't help but laugh when he heard this.

"So-and-so."

Someone behind him responded, Li Jingye jumped around, and then scratched his head and said, "Don't joke about the princess." ”

Gao Yang made a fortune again, and the small leather whip was inlaid with a few gems, and Jia Ping'an was a little greedy when he saw it.

"Many relatives in the clan came to me, saying that it was good to support the elderly in that place, and if I didn't sell it to them, I didn't respect the old, and I said that if I didn't respect the old, I wouldn't respect the old, what's wrong?"

Gao Yang is a person who is soft and not hard, except for Master Jia, of course.

She said disdainfully: "Later, Xiao Ling persuaded me to sell it, and I made a lot of money at once, but this money is too much and troublesome, and it is annoying to watch." ”

Jia Ping'an put his cheek on his cheek with one hand, "Do you know why it can be sold so well?" ”

Gao Yang shook his head, "I only need money, what else does it matter." ”

"Your Majesty has asked the well to be disinfected with quicklime in the palace."

Jia Ping'an felt that Gao Yang was unconscious, "I have made money, remember to send some good things to the palace." ”

Have a conscience!

But Jia Ping'an was not ready to give.

"Lang Jun, our family has spent a lot of money on dredging, and we have borrowed money, and we didn't make much money by selling the house to fill the shortfall."

Du He was very heartbroken, and felt that his own Langjun had planned like this, and he had done it in vain, which was very unfair.

"Don't worry."

Jia Ping'an didn't worry about this at all.

"Wuyang Boke?"

Du He went to open the door.

Outside the door was a middle-aged man, who smiled and said, "A certain is the steward of the Liang family, who came on the orders of Ah Lang." ”

He turned around and said, "Bring it here." ”

Du He was still puzzled, when he saw several carriages coming slowly.

"Ah Lang said, Xiao Jia did a good job this time, the Liang family made a lot of money, but the draught did not forget to dig the well, this is a thank you gift."

Truckloads of money were pulled in.

And then there's that.

"From a certain British government."

"So-and-so is ......"

The carriage was endless, Du Hexi couldn't close his mouth, and asked Cao Er to hurry up and get wine and food to entertain the guests, and he had to take someone to put the money into the warehouse, and by the way, he was very busy.

Jia Ping'an came out to say a few words at the beginning, and then went back to the study.

After cleaning up, Du He came to the study and said, "Lang Jun, the treasury is full, if there is any more money, our family will have to build a warehouse." ”

This product is not good, and then counted the people who sent the money: "The princess didn't come." ”

"Don't count on that over there."

Jia Ping'an and Gao Yang's way of getting along doesn't need to be like this, if Gao Yang sends money, it will be cliché.

"Lang Jun, now that I think about it, why are those people so eager to sell the house?" Du He thought something was strange about this.

"Someone's pouting behind their backs."

Jia Ping'an ordered: "Call the lender." ”

Later, the man who lent the money came.

"The Jia family never defaults, let's come according to the contract, calculate the interest day by day, and settle it today with interest."

The man's face turned green.

If you borrow for a short period of time, the annual interest rate of 8 cents is really not high.

Jia Ping'an repaid the money not long after he borrowed it, and he earned it reasonably, but it looked like a desperate loss of dirty pants.

After he left, Du He was a little curious, "This person is so kind." ”

"He was digging a pit, thinking that the Jia family would not be able to pay back the money within half a year, so the money was considerable. But who would have thought that a certain person had never thought of borrowing for a long time, so his purpose was frustrated, and the person behind him was going to cry. ”

……

"Wang Shangshu, what kind of disinfection did Jia Ping'an get quicklime, and those houses were all sold."

Zhou Xing knelt in front of the desk, his face ugly.

Wang Qi put down the needle and thread, slowly raised his head, his eyes were extremely cold, "Quicklime may be sterilized?" ”

"I don't know."

"Why would those people buy it?"

"It is said that the palace is also disinfecting the well with quicklime."

Who can have the nobles in the palace spare their lives?

Wang Qi looked at him blankly, the corners of his mouth slightly curled, "So...... All of our plans have failed? ”

"Yes!" Zhou Xing lowered his head, and the sense of humiliation made him want to go crazy.

"Not only did he reverse the situation, but he also used our money to buy a house and made a lot of money, that is, all the money he spent dredging was back, and he still made a profit."

Wang Qi's gaze slid and he looked at a long needle on the table.

Zhou Xing's body trembled, "Yes." Someone wanted to lend him money when he was desperate, so it would be more difficult for him......"

"But you failed." Wang Qi's face gradually turned red, he gasped, tearing his clothes, "It's uncomfortable!" ”

Chen Erniang was just outside the door, she heard this, but she didn't turn back.

Zhou Xing hurriedly went over to help and opened Wang Qi's mind.

Wang Qi gasped, suddenly grabbed Zhou Xing's wrist, stared at him deadly, and hissed: "Did you lose to him?" ”

Zhou Xing subconsciously said: "No, we haven't lost yet." ”

Wang Qi sneered: "Will he wag his tail and beg for mercy? ”

This man is crazy!

Zhou Xing nodded, "Definitely." ”

"It's Wang Shangshu!" Wang Qi suddenly laughed, "Lost, this time he lost, he actually thought of a means to transform the canal into a garden, it's better than that!" Someone is not as good as him, hahahaha! ”

This man is not crazy!

Zhou Xing's heart was relieved.

Wang Qi clenched his wrist, "But you let people lend it to him, it's stupid." You say, "What should I do with you?" ”

Zhou Xing's heart tightened, "A certain wish to be punished!" ”

Wang Qi said coldly: "Look up." ”

Zhou Xing raised his head, and Wang Qi waved his right hand.

A sharp stinging pain came from his cheek, and Zhou Xing couldn't help but scream.

"Ahh

Wang Qi pricked his cheek with a long needle, gasping and said, "Incompetent, hurt someone who is embarrassed and stabbed you to death!" Pierce you! ”

Chen Erniang felt that something was wrong when she heard this voice, she was too crazy, so she glanced at the room.

Zhou Xing knelt there, his head tilted almost like an iron bridge, and Wang Qi was poking his cheek with the needle he was doing. His cheeks were flushed, his eyes were red, and he was kicking and screaming......

Chen Erniang was shocked in her heart and quietly avoided it.

Wang Qi was confident and almost arrogant, but after being hit by Jia Ping'an again and again, he gradually became like this.

The more she thought about it, the more terrible she felt, so she said to someone and quietly went out.

When she arrived outside the imperial city, she said that she had something to ask to see Jia Ping'an, who was a hundred horsemen.

The sergeant guarding the door saw that she was plump, and couldn't help but say ambiguously: "Uncle Wuyang is handsome, you are also suitable." ”

What's appropriate?

Chen Erniang was puzzled.

She was standing outside, a few sergeants chatting behind her.

"It's good to wait for this."

"Why?"

"I know it hurts."

"It's just too powerful."

"Wu Yangbo is powerful at first glance, would he be afraid of her?"

"Yes! This woman is plump and has come to look for Uncle Wu Yang several times, so it can be seen that she secretly likes him. ”

"Take the secret out."

Chen Erniang felt hot all over, and the embarrassment made her want to find a crack in the ground to get into.

"Erniang?"

Jia Ping'an's voice came from behind him, and Chen Erniang turned around, "Jia Lang." ”

Why is this woman so crimson and shy?

Jia Ping'an subconsciously felt that she had a fever.

"Jia Lang, I have a relative who is sick......

"What are the symptoms?"

This woman actually came to ask this, which made Jia Ping'an feel a little funny.

But be serious, and make a show of concern.

Chen Erniang glanced at him, saw that he looked focused, with a concerned expression, and couldn't help but feel a little guilty in her heart.

"The patient was originally proud, but later frustrated, his temper became worse and worse, and he also liked to do needlework, and when arguing with others, he liked to prick people with needles...... When he looks at people, his eyes are cold, but he is crazy when he loses his temper. ”

"It's perverted." Jia Ping'an asked casually: "Male or female?" ”

Chen Erniang hesitated.

Just a moment, Jia Ping'an almost burst out laughing.

The patient was originally proud, Wang Qi was known as a scholar, but no one appreciated it, and this arrogance and confidence made people speechless.

Later, he was frustrated, and after meeting Jia Ping'an, Wang Qi was hit several times, and the so-called Shangshu talent suddenly became a joke.

That thing actually started to embroider?

"It's a man." As soon as the words came out, Chen Erniang felt relaxed.

"That's perverted."

Jia Ping'an said very seriously: "These people are moody and ruthless, although they are relatives, you have to be careful." ”

Wang Qi was actually made a pervert by him......

Also play with needlework.

Jia Ping'an instantly thought of the sect leader.

……

There are also book friends with monthly passes...... Ask for a ticket.
