Song Ningyu, who was hiding on the back of his hand, grabbed it in his hand, and found that his palm had been blown up, and he could still see the powder continuing to react in the blood and water, making a hissing sound, all like this, he couldn't throw it for the rest of his life.

"I'm fine, I want to take the bowl farther away." Mu Beiyuan has observed that Song Ningyi's heart is very soft in the past few days, and even if he finds out that he is calculating her, as long as he shows an injured expression, she will still feel distressed.

Song Ningyi frowned, she didn't have to save him.

What kind of experiment did she do, and she would have no points in her heart? However, looking at his painful expression, she couldn't bear it.

He took the spiritual water and slowly rinsed his wounds.

"Gardenia, you don't have to worry, I'm fine." Mu Beiyuan's lips were slightly white, but his voice was unexpectedly gentle.

“……”

"Are you really angry? I was just worried about you, afraid that you would get hurt, so I covered it with my hands. Mu Beiyuan looked very painful and withdrew his hand.

"Don't move!" Song Ningyu said with some displeasure.

"Hiss~, it hurts a little!" After two days of observation, Mu Beiyuan found that she is really a bad person, as long as you pretend to be weak, you will not abandon you if you know that there is fraud.

"I'll tap it, and I'll be fine in a moment." Song Ningyu was cleaning the wound while blowing the most air.

The warm breath spread from the palm of his hand to the tip of his heart, making him fidget, obviously deliberately punishing her for not putting all her attention on herself, but she found that it was indeed herself who suffered in the end.

After a while, Song Ningyu cleaned the wound and bandaged him.

The air in the room solidified again.

Song Ningyu also put her energy into the experiment again......

This time she learned from her experience and added two different things to two bowls of water.

A bowl of water was filled with the crystals after calcining baking soda, and they melted immediately when they were submerged in the water;

Another bowl of slaked lime was put in it, and it was poured down to turn into a bowl of gray-brown lime water, just like Song Ningmo said.

Slowly, the solution of white crystals was poured into the bowl of dirty water.

At this time, she missed her chemistry teacher very much.

I hate myself at that time, why don't I study harder, so that she can use it when she has the opportunity to experiment.

As soon as it is poured down, it slowly reacts, and the dirty water begins to become transparent, and slowly begins to become clean, and the white flocculent matter continues to increase.

The corners of Song Ningyi's mouth flashed with a bright smile, this is it!

The coveted caustic solution is finally complete.

At this time, the cup has slowly become hot, and even a little hot.

"It's amazing, I didn't expect you to do tricks?" Mu Beiyuan said, but the disappointment was still written in the corner of his eyes, because he had waited for so long, he thought that she would bring him some surprise, but it turned out to be too disappointing, and his fingers couldn't help poking the "white flower" in the water.

"Don't move!" Song Ningyu quickly grabbed Mu Beiyuan's outstretched fingers, but-

"Shhh

Song Ningyi had already prepared an emergency plan for this kind of emergency, and put it aside for backup at any time.

Seeing that his fingers were instantly red and swollen, she grabbed his fingers and threw them into the thick bowl next to her.

Mu Beiyuan was a little afraid of this bowl of water, and subconsciously retracted, but was stunned by Song Ningyi's temper.

The sour smell of vinegar kept coming from between his fingers, and the warm and cool water continued to wash away the burning sensation on Mu Beiyuan's fingers.

What surprised him even more was that he hadn't seen flowers in the water, this kind of trick would be staged at a banquet every year, but he couldn't touch the flowers in the water who hadn't seen them.

If this kind of thing is produced in large quantities, can it directly dissolve a person......

Mu Beiyuan suddenly realized this and couldn't help but shudder.

When Mu Beiyuan's fingers were good, Song Ningyu took his fingers out of the vinegar, dried them with a cloth, and smelled the bowl of vinegar by the way, and found that there was no taste anymore, leaving a little white and white crystals in the bowl.

As soon as Mu Beiyuan put his fingers in, he smelled that it was a bowl of vinegar, but now he followed Song Ningyi's gaze and found that the bowl of vinegar no longer smelled of vinegar, and it couldn't even be called coarse, and the white crystals at the bottom of the bowl had also sunk to the bottom.

The burning sensation on his fingers has also gone, and the blisters of a finger are still shouting about what has just happened.

When Song Ningyu put his energy back into the bowl of solution, Mu Beiyuan's palms were still sweating nervously.

Finding a small piece of cotton cloth, separating the white substance in the solution, the movement was extremely gentle, and Mu Beiyuan's heart also went up and down.

Song Ningyu then poured the remaining snake oil from last time into the bowl of water.

The snake oil has solidified, and Song Ningyu only needs to slowly enter it one by one, the clear water becomes turbid, slowly becomes viscous, and the water slowly follows the color of the tongue and becomes milky white.

"It finally worked." Song Ningyu stretched her waist and said.

"It's so troublesome to get a slimy cup of water that you can't drink?" Mu Beiyuan's tone was cold but very disgusting.

"Soap! You'll see results tomorrow. Song Ningyu said happily.

But I feel that this method is really too troublesome, as a modern person, she can't accept it, let alone the ancient people, it will be even worse if she hurts herself again.

Then Song Ningyu experimented with baking soda without heating, directly dissolved in water, and fused with lime slurry, and found that it was also successful.

I suddenly remembered that my chemistry teacher had said that baking soda was turned into water and soda when it was heated, and my face instantly became solemn, and I felt that I had just been a fool.

Fortunately, no one knew, otherwise it would be really faceless, Song Ningyu secretly glanced at Mu Beiyuan,

Fortunately, he was not discovered, and he quietly breathed a sigh of relief.

"You don't need to heat it up, why did you just heat it up once?" Seeing her weak expression, Mu Beiyuan immediately guessed what she was weak about, and said it deliberately.

Song Ningyu, who was poked in the center, was like a cat whose tail was stepped on, and it exploded in an instant.

puffed out his cheeks and said angrily, "I'm willing, I want you to take care of it!" ”

Looking at her puffing out, Mu Beiyuan felt that her mood was inexplicably smoother, and she felt that she was very cute, especially her bulging cheeks, and she wanted to go up and poke it twice when she looked at it.

Mu Beiyuan thought so, and that's what he did.

The fingers poked Song Ningyi's face as if they were not braining, and they also dubbed "snort~".

Song Ningyu was stunned.

"If you're discouraged, don't be angry, then you will be like a kitten with fried hair, and you will be called meow in the future." Mu Beiyuan's face was still faint and expressionless, and he said jokingly.

"You...... Immature! Song Ningyu gently pushed his outstretched fingers and rolled his eyes.

Mu Beiyuan looked down at the fingers that were pushed back by her, and he was also stunned, yes, it was really naïve, when would he make such a childish move.

But, it didn't feel bad, her cheeks were as tender and fluffy as he thought.

"Does it have to be made with snake oil?" Mu Beiyuan hid the throbbing in his heart and said seriously.

"No, it's just that there is only snake oil at home, any oil is fine, as long as it is oil." Song Ningyu replied very casually.

"And what is your favorite oil to make of?"

"Olive oil, or mutton fat" Song Ningyu recalled, remembering that handmade soaps were made of olive oil in the past, as for mutton fat, a very famous soap in Australia seems to be made of mutton fat.

"You probably haven't done it before." What Mu Beiyuan wanted to ask was why she used stones to make pancreas, but even if she asked, she might not be able to answer, so she turned a corner and asked.

Song Ningyu nodded briskly, "Yes, it's the first time to do it." ”

"Then you also learned this from your master?" Mu Beiyuan's heart was beating up and down, for fear that his suspicion would keep her away from him, which would outweigh the losses.

Song Ningyi's eyes rolled, and she said nonsense, "Yes."

In the past, I always had to do laundry, but my master and I didn't want to do it, so he did this, and then I watched it once.

But the things he uses are different from this one, and I also made them tentatively. ”

"Then why do you know that all oils are fine, rapeseed oil is dark green, soybean oil is yellow, animal oil is milky white, it is not a thing at first glance."

"The gentleman who said that he was far away from cooking, you know a lot." Song Ningyu said in disgust.

"Haha, there is no one to take care of me at home, and if I don't cook anymore, won't I starve to death a long time ago?" Mu Beiyuan thought in his heart that if there is a beauty like you, I am also willing to wash my hands and make soup for you.

"Cut," Song Ningyu continued, "oil is oil, although there are many kinds, but you also know that they are all oil." ”

Mu Beiyuan was stunned for a moment, "Your statement is fresh." ”

"Originally, there are good and bad people, some people wear silk and satin, and some people can't afford to eat, but as long as they are people, they only have one life." Song Ningyu's eyes darkened after speaking.

She traded another person's life for another life.

Therefore, she should cherish this life even more, so that the person who gave her life can rest in peace.

Mu Beiyuan didn't continue to speak, sitting silently in the chair, recalling what she had just said.

Yes, people should be equal, but there are too many injustices in the world.

Let people divide three, six, nine, etc.,

She saw it clearly, but it was this transparency that made him feel that she had a sense of reverence for a bodhisattva.

Will she leave quietly after purifying all beings?

No, he's hers,

I won't let her go.

When the soap was formed, Song Ningyu took the meridian and opened it with relish.

Mu Beiyuan saw her reading quietly in front of the clay table, and he had a feeling that the years were quiet.

"Is Ernier in the house?" Footsteps could be heard outside.

"Ah, come in and say." Song Ningyu put down the book and looked towards the door.

Walking in from the door was an elegant scholar in a gray coarse cloth robe, but facing a villain who looked a little sharp-beaked and prone to inflammation.

"Ernier, I heard that you bought a lot of books." The man spoke.

Song Ningyi looked at it, this person was the only scholar official brother in the family who hid her rations, "Yes." ”

"That's right, I know you can't read, and the books were bought for me, so I'm here to pick up the books." Brother Guan said straight to the point.

"I'm sorry, the book was bought by Brother Song Yuan for himself." Song Ningyu frowned.

"Brother Yuan, you are also literate?" Brother Guan spoke, but there was a trace of disdain in his eyes.

"Of course, Brother Song Yuan is a miracle doctor, not only literate, but also has good medical skills. Most of them are medical skills, so I'm sorry I can't give it to you, but there are a few travelogues that you can take and see first. Song Ningyu didn't like the kind of disdainful gaze in the corner of his eyes, and replied quickly.

When Brother Guan heard that there was a travelogue, his brows tightened, and he opened his mouth to teach, "You actually bought a travelogue?" Ernier, it's not me talking about you, you're spending money too much. ”

"Okay, I'll pay attention next time." Song Ningyu responded.

"Forget it, I'm too lazy to say you, bring the book, don't break it, I'll sell it in the town in a while, and I can exchange it for some pen and ink money." As soon as he stretched out his hand, he began to snatch the book in Song Ningyu's hand.

"Books, you can read them, but you can't sell them." Song Ningyu retracted her hand and said solemnly.

"I said that you are illiterate, can you understand, he is still a doctor, if he is a doctor, why don't he treat himself when he is injured and unconscious, he is also a half-hung person at such an age, what kind of books do you read." Brother Guan raised his voice and spoke.

Song Ningyu threw the book on the table, stared at it and raised her voice, "Then you can't sell books!" ”

"It's the end of the month, and I have to pay next month's money, the way the family is now, you are holding a broken book and not letting it be sold, don't you see that I am having a good time." Brother Guan was so angry that he told the truth.

"Hug ...... I'm sorry. Song Ningyi's arrogance retreated suddenly.

Brother Guan thought that he could get the maintenance of the family in exchange for such a shout, but no one came over, but he accidentally heard Song Ningyi's apology, and she would apologize too?

sat down and looked at Song Ningyu angrily.

It's a little strange, usually his whole family comes over to accuse the money-loser, why hasn't any of them shown up today, not even his mother.

Brother Guan waited for a while and didn't see anyone to defend him, so he had to bite the bullet and said,

"Actually, it's not that there is no way, since Brother Yuan is literate, can you ask him to copy the book with me, I can't help it, so I want to ......" Brother Guan is a master who can bend and stretch, and he knows that he can't take the book, but he always has to make some benefits before he is willing to go.

"Oh? Copying books? Is a book copied over and over again? Song Ningyi suddenly remembered printing in her mind.

"That's right, copy a book of 200 texts, as long as you can copy 10 copies, my bundle is enough." Brother Guan raised the book in his hand and said.

"What if you write too much? For example, a hundred copies, will he not want it? Song Ningyu asked.

Brother Guan glanced at him, and said disdainfully, "Even if you copy a thousand copies, the bookstore will accept them, but I don't know if you have the ability to copy so much." ”

Song Ningyu took the book in the hand of Brother Guan'er, a thin one, just over 20 pages,

The cover is wrapped in dark blue burlap, which looks like a book cover, sealed with coarse twine, and a pendant is hung on it, on which is written "Shangshu * Xia Biography"

It seems to be some prose or poetry handed down from the Xia Dynasty.

Song Ningyi raised her eyebrows and said, "Oh." That means you have a market. Bring the book, copy a hundred copies for you tonight, but another condition, Ming'er, you take the book and go to sell it with Brother Song Yuan. ”

She didn't believe in Brother Guan'er, she always felt that he was not a good person, and Mu Beiyuan was more reliable.

"Good. However, if you don't finish copying, then next month's bundle, you can figure out a way. Brother Guan said sarcastically, it's really a village girl with long hair and short knowledge, it's good if you can copy it five times a night, and you want to make a hundred copies, let's talk about it.

"Good!" Song Ningyu nodded confidently, "If it's enough, then you won't have a share in the rest of the money." ”

"Good!" The corners of Brother Guan'er's mouth twitched, and he walked out, looking like he was watching a good show.

Mu Beiyuan took a hundred copies of rice paper, cut it into the size of a book, and began to copy the first one silently, he believed her, as long as she said it, he would do it, even if it was wrong.

Song Ningyu took a radish from the kitchen, cut it into the size of a book, and drained the water on the surface of the radish.

While continuing to look at her meridians, she sat and waited for Mu Beiyuan to copy the book slowly.

About half an hour or so, Mu Beiyuan's first piece of paper had already been copied, and he pretended to be very tired and said, "Gardenia, my hands are injured, and I am still helping you copy books, I am very tired." ”

Mu Beiyuan, who was accustomed to a cold expression, matched such a coquettish tone, this contrast made Song Ningyu couldn't help laughing.

"You...... Ha ha. Song Ningyi almost laughed.

Mu Beiyuan looked at Song Ningyu with annoyance, he showed favor to others for the first time, but he was mercilessly ridiculed.

How can this be reasonable, he is a dignified god of war.

It's so angry!

"Isn't that funny?" Mu Beiyuan was angry, and when he saw that she kept laughing, he became even more angry, "I'll let you laugh, let you laugh enough." ”

Quickly walked to Song Ningyu's position, squeaked Song Ningyu's waist with both hands, and the itchy Song Ningyu continued to laugh while hiding.

"You still laugh......" Mu Beiyuan said angrily, "Don't laugh." ”

While talking, he went to catch Song Ningyi, wanting to squeak her until she admitted her mistake.

Song Ningyu surrounded the table, adding fuel to the fire while dodging, "You can't catch me, you can't catch me!" ”

The two of them played a game of cat and mouse around the table.

"I'll let you escape!" Mu Beiyuan jumped directly in front of Song Ningyu on the table, grabbed her waist with both hands, and kept squeaking her itchy flesh.

Song Ningyi's smiling flowers trembled.

"Don't you dare to laugh at me." Mu Beiyuan didn't even notice that his vest had already fallen to the ground at this time, and he was happy like a teenager.

"Don't dare." Song Ningyu screamed and stepped back.

Without paying attention, with the sound of "ah-", Song Ningyu tripped over a jar in the room.

Mu Beiyuan was just playing with her, he didn't expect her to fall, so he hurriedly pulled hard, for fear that she would fall and break somewhere.

The strength was not well controlled, Song Ningyu was dragged by him, but threw herself into her arms.
