She took out the crockpot she had brought out of her home, carefully scraped it with a bamboo skewer, and collected it little by little into the crockpot.

About a pillar of incense, a full clay pot was collected, and there were still a lot of white crystals on the wall, and it didn't seem to be missing a little bit because Su Wanyu scraped a jar down.

After getting the things, Su Wanyu quickly got out of the thatched hut and ran out a few steps, until she couldn't smell the stench, she took a few breaths and took a breath of fresh air.

Chun Tao on the side was also inhaling heavily. After relieving her breath, Chun Tao asked suspiciously:

"Miss, what is this?"

Su Wanyu smiled and said, "This is saltpeter, and our Su family's net worth may depend on it." ”

"Miss......"

After a while, Su Wanyu and the others went home.

After entering the house, Su Wanyu went straight to the stove and took a wooden basin for washing her face. Draw water from the well and fill the basin with water. He took a small copper kettle and filled it with half a pot of well water.

She placed the copper kettle in the center of the tub and dipped it in the well water. Then she slowly poured the saltpeter that had just been scraped from the hut into the wooden basin.

Chun Tao stood aside, looking at Su Wanyu inexplicably.

Su Wanyu still had that uncertainty in her heart, and because the matter of ice making was beyond the cognition of this era, she didn't say it to anyone before the final result came out, including Chun Tao.

At this time, Su Wanyu stared closely at the wooden basin and copper kettle, and her heart was pounding.

I saw that the water in the wooden basin slowly condensed, and a layer of ice floated on the surface.

Gradually, the well water in the copper kettle also became sick. It's not very solid, but it's really winter.

Cracks on the ice bloom like flowers.

It turns out that this thatched house has been used for a long time, and saltpeter will be produced on the wall. Whereas, saltpeter enters the water and absorbs a lot of heat. The temperature of the well water is much lower than the temperature of the air. In an instant, a large amount of heat is sucked away. The temperature of the water drops sharply, and when it reaches below freezing, it condenses.

And this copper kettle is an excellent medium for heat conduction. The well water in the copper kettle also froze all at once.

The water in the tub already contains saltpeter, and it is no longer possible to eat it. But the ice formed in the copper kettle is clean and edible.

Su Wanyu's heartbeat gradually calmed down, but her eyes became hot.

Her eyes were warm and her heart was full of mixed feelings. In the darkness of the land, there will eventually be a door for people to see the light. In times of confusion and confusion, there will eventually be a path that allows people to see hope.

Su Wanyu picked up the cup, took out a piece of crushed ice with her hand, put it in her mouth and chewed it, it was refreshing and cool. In this hot summer, it is indescribably comfortable.

"Miss, this, this is ......" Chun Tao's gentle eyes were full of incredible shock.

Su Wanyu nodded with a smile: "This is ice." ”

Aunt Wu, who was kneading dough in the stove room, couldn't help but rub her eyes with her hands when she saw this scene. It didn't even occur to her own hands full of flour.

With this kneading, the flour comes into view.

"Ouch." Mother Wu called, I don't know if it was because of the pain in her eyes, or because of the surprise that Su Wanyu made ice.

"Aunt Wu, be careful." Su Wanyu hurriedly said: "Wash with water." ”

"Miss, is this the ice you made just now?" Mother Wu didn't have time to take care of her eyes and asked.

"yes, it's made of ice. We're going to open a cold meal and make money on ice. Su Wanyu said.

"It's really not my presbyopia." Mother Wu said.

Su Wanyu shook her head with a smile, patted Mother Wu, picked up the cup, and entered the main house where Mrs. Su was.

"Mother, what do you think this is.?" Su Wanyu raised the curtain and said to Mrs. Su with a smile.

"What an old man, still like a child." Mrs. Su said angrily, saw an irregular ice cube in Su Wanyu's hand, and said, "Where did the ice come from?" ”

Su Wanyu told Mrs. Su the ins and outs of ice making one by one.

"Really?" Mrs. Su said: "It's really unbelievable. ”

"Really, trutruly, truer than pearls." Su Wanyu said

Seeing that Su Wanyu was serious, Mrs. Su asked suspiciously, "Wanyu, when will you learn such skills?" ”

Su Wanyu hesitated, she had no way to tell Mrs. Su the truth about this question, so she closed her eyes and said nonsense: "Mother, it's all miscellaneous."

Mrs. Su said: "You, don't study hard, learn some messy things." ”

The original owner was born in a wealthy businessman, and her family was not strict with her homework. Mrs. Su thought that with her family's wealth, she could always make her daughter worry about food and clothing in this life.

Therefore, Su Wanyu is illiterate, so she doesn't study any homework, but is interested in miscellaneous books and novels, and she reads idle books to pass the time when she has nothing to do on weekdays. Now, Su Wanyu has passed this hurdle by mistake.

Mrs. Su said, "It seems that this summer, we also have ice to eat." ”

Su Wanyu said: "Mother, it's not just ice to eat, we sell the ice." Or open a cold food restaurant, you can make money to pay off debts. ”

Mrs. Su was silent for a long time. After that, she sighed slightly and said: "The price of this ice is not cheap, and it will make money to sell it, but my mother's biggest hope is that you can marry a good family as you wish, be plain and bland, and live happily." ”

Su Wanyu said: "What my mother said is right. But making money is not contradictory to marrying. You can make more money and have more dowry.

Besides, I still have my mother and Cheng Ze, with this ice, we can open a store, we can pay off our debts, and both my mother and Cheng Ze can live a good life,"

Su Wanyu said softly: "You should take medicine in the future." She looked at Mrs. Sue, her long eyelashes blinking.

Mrs. Su stroked Su Wanyu. There is hope, who wants to go that dead end. The method she had thought of before was also a last resort, so she nodded slowly and said:

"It's very hard to do business and open a store, and you have to show your face."

"Mother, it's not hard, you must give it a try if you have such a good opportunity." Su Wanyu said.

Mrs. Su looked at Su Wanyu's eyes full of hope and confidence, and she couldn't bear to refuse, so she said:

"Yes, it's okay to try."

Su Wanyu pulled out a big smile and looked at Mrs. Su.

Mrs. Su said angrily: "You kid, you and Cheng Ze are really two different temperaments.

Ever since you were a child, you've loved to read messy books and think about weird things. Cheng Ze likes to read sage books, exactly like his father. ”

"What books does Daddy like?" Hearing Mrs. Su mention Master Su, Su Wanyu was a little interested.

"He, he likes those subsets of scripture and history, I don't know, I think he is going to take the top exam. Others say that he is an honest and trustworthy Confucian businessman, but I think he is a nerd in reading. Mrs. Su said, a smile in her eyes.

"Why didn't Dad take the top prize?" A man who looked like a dumbfounded scholar appeared in Su Wanyu's heart.

"Before I married him, he went to the capital to study. Later, when he came back to inherit the family business, he stopped studying. Mrs. Su said.

Saying two words about Master Su, Mrs. Su had a look of remembrance on her face, and her face was sad.

Su Wanyu didn't dare to mention Master Su's affairs anymore, and started a family routine with Mrs. Su until nightfall.
