Dong Rong still felt panicked in her stomach at this time, and she couldn't eat anything, so she hurriedly waved her hand and excused herself, "No need, Dad, we're not hungry." It's just that I'm a little tired from the journey, so I'm going back to the room. After saying that, she pulled the stupid pillar out of the hall.

Mrs. Cao thought she had pinched her daughter-in-law, she was very proud, and snorted coldly, "Even if she still has some eyes." ”

Old man Cao knocked his chopsticks heavily and reprimanded in a low voice, "How many times have I sued you, you don't care about the pillar." Now that he has married his daughter-in-law, don't mix the affairs of the two of them! ”

Mrs. Cao was extremely aggrieved, and threw down her job and shouted, "What are you talking about, it's true that I'm his stepmother, but haven't I treated him well all these years?" You pat your conscience and say, when you went out to work, you didn't earn much money, but you gave birth to this fool and brought it back, did I say anything? Not only did he not say a word, but he was in pain as if he was his own, and he was taken care of properly with everything he ate, drank, and dressed. Now that my daughter-in-law has also married, will I put on my mother-in-law's shelf and enjoy the blessings of my daughter-in-law? ”

Old man Cao was very annoyed by the old woman's snatching of Bai Yitong, opened his mouth as if he wanted to say something, but swallowed it back for some reason, and finally got up and flicked his sleeves and walked away. Leaving Mrs. Cao grabbing the dishes and smashing her anger, she finally looked at the East Chamber, which was silent, and was even more angry in her heart.

Dong Rong didn't know that Mrs. Cao had recorded all her grievances on her head again, of course, even if she knew, she wouldn't care, and at this moment she was devoting herself to the ice making experiment.

In the center of the east chamber there are two clay pots, one large and one small, the small clay pot is filled with most of the cold water in the big clay pot, and the silly pillar holds the gourd scoop in one hand and the wooden bucket in the other, and carefully adds water to the big clay pot. When the amount of water reached half of the position, Dong Rong opened the oil paper bag in his hand, sprinkled a small half of saltpeter powder into the large clay pot, and then picked up a wooden stick and stirred it vigorously. The saltpeter powder reacted violently when it encountered water, and quickly absorbed a qiē heat from the outside world, so the water in the small clay pot froze at the sight.

Dong Rong's face was overjoyed, and she reached out and knocked on the ice but found that it was not frozen. She frowned and carefully recalled the details of her father's ice-making when she was a child, and couldn't find anything wrong, and then a small hard lump in saltpeter powder fell into the pool and made a tinkling sound to remind her. The saltpeter powder zuò process in this time and space is much inferior to that of modern times, and the purity is much inferior in all aspects, and the proportion of natural application is also higher.

If you find the crux of the problem, it will be much easier to solve the problem. Sure enough, another large handful of saltpeter powder was sprinkled into it, and the ice cubes in the small clay pot froze solidly. Dong Rong picked up a small clay pot and pasted it on her face, feeling a chill in her heart, and she couldn't jump on the spot a few times with joy.

The stupid pillar squatting on the side seemed to be shocked by this magical change, his face changed rapidly, and his eyes looking at Dong Rong contained a lot of exploration and doubts.

Dong Rong was completely immersed in the joy of the success of the experiment, and did not notice his abnormality at all. As the saying goes, a good start is half the battle. As long as she manages it carefully, this small ice cube business may be enough to support her for a lifetime. Of course, the prerequisite is to do a good job of secrecy, if everyone has mastered this method of making ice, she will not be able to sing.

"Zhuzi, we are playing in the water like this today, you must not talk about it to others, you know?" Dong Rong put the ice basin aside and carefully instructed the pillar, for fear that this accomplice would accidentally leak the shocking secret.

Silly Zhu'er nodded, and asked in a low voice, "Can't Daddy say it?" ”

"Can't!" Dong Rong pretended to be vicious and threatened: "If you say a word, I will ignore you in the future, never take you into the city again, and never buy you delicious food." ”

Silly Zhu'er rolled his eyes and responded, "Okay, I have to eat two meat buns a day!" ”

"Are you really stupid or fake?" Dong Rong pinched the stupid pillar's arm with her hand, and scolded with a smile, "I actually learned to rob while the fire is burning, buy, as long as you listen to me, I will buy you meat buns every time you enter the city in the future, right?" ”

Silly Zhuhan smiled and ran out with a clay pot to "destroy the corpse and destroy the traces". Dong Rong was afraid that the Cao family would see it and give a few instructions, but she didn't want to be stupid but she ran away in a blink of an eye, so she had to shut down and carefully calculate what else to add.

Silly Zhu'er hugged the ice basin and avoided the villagers on the road all the way, and soon arrived at Dr. Feng's small courtyard. Feng Lao was about to have lunch at this time, and there was a big bowl of white raw noodles on the stone table in front of him, and a small blue and white porcelain bowl next to him was filled with half a toon shredded pork marinade, which was oily and fragrant, which made people drool.

The old man suddenly saw the disciple coming, so he asked with a smile, "Huaide, why did you come here at this time?" But I don't like the Cao family's food is too coarse, so let's eat a bowl of lo noodles with me. After speaking, he shouted to the breeze on the side to cook an extra bowl of noodles in the kitchen and send it over.

Silly Zhu waved his hand to signal that Qingfeng didn't have to be busy, and then pushed away the dishes and chopsticks and put the ice basin on the stone table. Feng Lao looked at the transparent and clear ice cubes in the basin suspiciously, and asked, "Hey, where did you find the ice, but which big family in the city has opened an ice cellar?" ”

Silly Zhu squinted his eyes and was silent for a long time before he said, "It's not from the city, it's... Dong did it with his own hands. ”

"Dong?" Feng Lao thought for a long time before he reacted, and said in surprise, "You mean, this ice cube is your newly married little daughter-in-law..."

"Yes, I watched her make it." Silly Zhu took over Feng Lao's unfinished words, and at the end carefully explained what he had seen before.
