Chapter 139 Apprenticeship
Nan Rusheng took down the pot, put fine salt in the bamboo tube, and said, "Mother, take a look."

"It's white and clean." Nan Yu said happily while holding the bamboo tube, "Is this good salt?"

"That's right, although it's not the perfect salt, it's still better than the previous one." Nan Rusheng poured out a little and asked Nan Yushi to taste it.

Nan Yushi sipped some, and there was no strange smell, and the taste improved. The salt in the past was a big piece, and when you use it, you can only scrape it with a knife, and the taste is also very fishy. When used in dishes, it affects The taste of the dishes.

"Rusheng. How much does it cost to make this salt?" Nan Yu smacked his mouth and asked immediately.

"I didn't spend any money, I just took some wood." Nan Rusheng chuckled.

Nan Yu finally realized that there was a sound when she was cooking just now, and it turned out that Rusheng was picking up wood, so she asked why there was no more firewood when she turned around, and asked curiously: "The wood turned into ashes, like maple leaves. If the sand is gone, how can it turn into salt, don't lie to your mother."

Nan Rusheng was in trouble. She never said that the half-burned wood was used as activated carbon, so what activated carbon is, she had to explain it again. What's more, she directly told that salt was made according to carbon adsorption and evaporation crystallization.

She had long forgotten about these things, and her mind and shadow had eloped away.

She still remembers what these are for.

What's more, my mother can't understand.

"Matter and matter will react." Nan Rusheng looked at Nan Rufeng and Nan Yushi's puzzled eyes, and continued, "It's like salt will melt when it meets water, and iron will rust when it is permanent."

Nan Yushi is getting old, but he doesn't care about these things, it is enough to have a shadow of one thing in his heart.

Nan Rufeng was different. It was when she was very curious, but she thought about it seriously for a while, why did the salt dissolve into the water instead of the water into the salt grains, and why did the iron rust? Asked: "Sister, why?"

Nan Rusheng: "."

Sorry, she has no balance in her mind and cannot answer this question.

So, using one of the most common methods used by modern parents, he rubbed Nan Rufeng's head and said, "Rufeng, you are still young, you will know when you grow up."

o(*￣︶￣*)o Hey, she is still smart.

Nan Rufeng turned her head and asked Nan Yushi, "Mother, mother, do you know why?"

Nan Yu smiled embarrassedly and said, "Mother doesn't know either."

Nan Rufeng pouted and looked at Nan Rusheng, seeming to say, look, mother doesn't know, how can you lie to a child.

Nan Rusheng just wanted to beat this brother who is not easy to fool, so he forced a smile and said: "The answer to this question is very difficult. I will introduce it to you in a simple way tomorrow. Now let's cook vegetables with this salt and try it." smell."

Nan Rufeng was coaxed into the past. Anyway, he also knew that if he escaped the first day of the junior high school, he would not be able to escape the fifteenth day. His sister was at her house, and when the rooster crowed tomorrow, he would knock on the door.

Thanks to this fine salt, Nan Yu made a four dishes and one soup.

At this time, Ah Hua Banban was kneeling on the ground, raised his arms, and held a teacup, with a smile on his face, the words "I'm very happy today" came to his face, and the voice of milk was milky. With a hint of seriousness in his heart, he said: "Master, please allow the apprentice to serve tea."

Three eyes stared at Nan Rusheng. Nan Rusheng's expression was a little unnatural, but he was full of warmth. This was also the first time for her.

Nan Rusheng took the teacup, drank it down, remembered a sentence, and said lightly: "The doctor is benevolent, and saving lives and healing the wounded is the right way."

"Yes, apprentice remembers." A'hua put her hands on the ground and kowtowed three times.
