"Because the places where the water passes are different!"

A group of idiots, Jia Ping'an just fooled around.

The key is……

"Duke Qin is invited."

Qin Ping is here.

"Excuse me, Mr. Qin, how do you drink the water from the well in the past?"

"Sweet." Qin Ping said: "When I was young, and I was greedy for cold in summer, I would drink the well water directly. The sweetness is still unforgettable for me. But then it gradually changed, and the taste was weird. In recent years, it has become more and more delicious. It's not good to drink."

"Those rotten things gradually soaked in." Jia Pingan knew that what he had heard was false, "There are two ways. One, don't drink raw water, this is the iron law. Second, disinfect!"

"disinfect?"

Jia Pingan nodded, "Everyone, please take a look."

"Lime!"

The water in the well was emptied, and lime was thrown down from the top. Someone looked at it, but Li Yuanying, who was throwing lime, made a big move and even lifted the lime.

"Someone's eyes!"

The official covered his eyes and screamed.

"Get water! Here's water!"

Wang Zhongliang asked someone to help him to wash his eyes with the well water dug earlier.

"If you want to make him blind, just wash him with water." Jia Pingan looked indifferent.

"What do you mean?" Wang Zhongliang turned around and looked at him.

"Quicklime is highly corrosive, and it will react strongly when it meets water, burning..."

This group of pampered guys have never touched quicklime at all.

Jia Pingan got a handful of quicklime and sprinkled it in a bowl of water.

laugh!

Got mad.

Wang Zhongliang went limp all over, "Then what?"

"Here's the oil."

Isn't it fragrant with vegetable oil?

After washing the eyes with vegetable oil a few times, the official screamed: "A certain person must be blind, blind!"

"I can't be blind." Jia Pingan looked at his eyes, but they were corroded, but it was not serious, and it would be fine after a while.

"Go home and raise them."

Someone helped the official back, Wang Zhongliang asked, "Why?"

"I said..." Jia Pingan wanted to say that you didn't understand, but he still explained, "Quicklime will react when it meets water, releasing a lot of heat..."

The bowl of water was a little hot.

"Then why can it be disinfected?" Wang Zhongliang felt that this was unclear.

Jia Pingan deeply misses those years of study, "Because many germs have a substance called protein, quicklime can not only generate heat when it meets water, but also generate strong alkali... Heat cannot sterilize, but strong alkali can make the protein of those germs lose active, thereby completing the disinfection."

Everyone was dumbfounded.

Jia Pingan smiled wryly and said, "It's not that a certain person doesn't want to explain, but it's that he can't finish explaining for three days and three nights."

"A certain person is willing to listen for three days and three nights." An official seemed very interested.

"But you have to learn from scratch."

"Yes, I am eager to learn."

"It's a new learning." Jia Pingan said with a smile, "You have to learn it from scratch...that is a whole set of knowledge system, are you sure you are ready?"

"system?"

This is an unfamiliar word.

"Yes, for example, the protein mentioned before, such as the bacteria mentioned earlier, and how quicklime forms a strong alkali."

This is a huge system, and the official feels terrible just thinking about it.

"Is this new learning?"

"Correct!"

Quicklime goes down for disinfection, and no water is taken later.

"Is quicklime mixed with water poisonous?"

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

Three days later...

The wells that have been disinfected several times and cleaned several times are filled with water again.

"The taste has changed!"

Wang Zhongliang took a sip and said in surprise: "Although it still has a strange taste, it is a bit sweet."

"Boil it and drink it."

Jia Pingan ordered the well water to be boiled, and then made tea, and a group of people drank it by the well.

"...Jia Pingan drinks the most."

Wang Zhongliang also drank a lot, "He just drank soup like a meal, and asked people to add salt."

"It seems that there is such knowledge in the new learning." Li Zhi is not interested in the learning of the Imperial College, but he is quite curious about the new learning.

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

"Those mud and rocks?" Li Zhi figured out the truth, "I remember someone said that when I looked at the clear stream in the southwest, I felt bitter after drinking it, and I would die immediately. Later, someone went up and found that the source had Rotting leaves, and colorful pebbles..."
