The old man not only has to keep an eye on Sanqi, but also has to pay attention to his own ghost ideas at all times.

Suddenly, she regretted it.

It's better to kowtow every month than to report any ideas!

Ding Xuewei only felt that she lifted a stone and hit her own feet, and after being speechless for a while, she took the initiative to talk about ice making.

After listening to the principle of ice-making for a long time, he immediately sent someone back to the city to inform him of the stay, turned around, and asked, "What else did that grandmother teach you?" ”

"Ugh!" Ding Xue scratched slightly.

After a while, her eyes were full of determination: "Grandma only taught me the wonderful use of the two recipes of strengthening the spleen and stomach and dispelling dampness of typhoid fever, but did not teach me anything else. ”

“··· What else is inadvertent? The prefect asked, his eyes sharp.

If you were an ordinary child, you would definitely not be able to stand his kind of gaze, what kind of person is Ding Xuewei, leaders from all over the world are used to seeing it... On TV, on mobile phones, I really see a lot.

I basically didn't feel the pressure on him.

After scratching her ears in embarrassment, Ding Xue shook her head slightly: "I can't think of anything else." ”

The prefect frowned slightly, and his eyes became more and more aggressive, but unfortunately, Ding Xuewei is still the kind of person I want to learn from in more ways, but I just can't remember it.

A typical dead pig is not afraid of boiling water.

"Adult, this kid is indeed a little clever, but he is also very clever, and many things will only bring back some memories when they are faced." Old man Ding cautiously helped.

Ding Xue blinked slightly, looking innocent.

Human consciousness is uncontrollable, and most people who are unconsciously in contact with things will only remember, show, and think deliberately in the same unconscious situation, and most of the time they will not get the desired results.

Those deep and sharp eyes just stared at Ding Xuewei, and when she thought she was going to be forced, her eyes converged.

"After that, if you think of something, just try it, and if you need it, you can report it to the government."

Ding Xuewei was still thinking about the silk before, but now, she has no idea at all.

It's not that she's selfish and doesn't know how to share with others, but she's afraid that she's too provocative and provocative.

At this time, she was a little skeptical that she had made a mistake in her choice to keep a simple life at that time.

If you drill up at that time, this family will have to enjoy it in the capital!

There is no regret medicine in the world, even if you are really cheated by yourself, what else can you do except admit it, restrain your good mood, and experiment seriously.

That day, Chen Qing brought back a lot of saltpeter, and Ding Xuewei was naturally not soft when he started the experiment, and the customized ice bucket had not been delivered yet, so he could only use the things he had prepared before.

The big pot and small barrel, the round pot and the bamboo, all the things prepared before, were arranged for it at one time, and the dozen or so people who were accompanying the prefect were all commanded by Ding Xuewei.

"Don't shake your hands, don't let the water stop flowing, my lord."

"This lord, you move faster, so slowly, where you need to absorb the heat of the water in the jar, the temperature outside is enough."

"Uncle Zhang, don't move, what should you do if you move away from the cold air!"

"Your Excellency! Are you cold, cold is right, cold means that saltpeter melting will really absorb the heat next to it, this is half the success~"

Obviously, she did an experiment in junior high school, and she knew how to do it in one step, but Ding Xuewei did not ascend to the sky in one step, but spread out a piece of boss, first put water or saltpeter first, add more water at one time or slow down with thin water, but any idea that could be tossed, she let it toss, it was the prefect who was solemn and calm, and lost her reason in her chaotic pace and voice like ants in a hot pot.

Her mind is full of this adult she shouted!

"Xue Wei ~ Yes, there is ice slag, there is ice slag!"

The old village chief didn't know what the ice cubes looked like, but he knew very well what the ice ballast looked like, and the old village chief, who accidentally saw the scum in the jar, jumped up and squinted like a three-year-old child who begged for rock sugar gourds.

"Really?"

Ding Xue asked slightly and walked towards the two.

Old man Ding and the old village chief are in a group, the old man Ding puts saltpeter, and the old village chief stirs the water in the ceramic jar.

Their group is not only the size of a jug, but also a lot of water.

At this time, no one should be the one who succeeds!

The doubts in his heart were instantaneous, and when Ding Xue squatted down to the two of them and saw the generosity of Old Man Ding's saltpeter, he immediately understood.

Being stared at by Ding Xue's speechless gaze, Old Man Ding suddenly understood that he had done something wrong, and when he started again, the pile of saltpeter turned into two.

However, the water in the pitcher had begun to freeze, and there was a large amount of saltpeter in the water that had not melted, and he just didn't put it in it anymore, it was enough!

"There is really ice slag, it seems that more water and more saltpeter is the right way to make ice." Ding Xue slightly retracted her mind and burst out.

The crowd who originally wanted to come and see suddenly rested, and they should pour water and pour water, and they should put saltpeter on the ground.

——

"Oh, there you have it, I have it here!"

——

"Ahh Ice, ice! ”

——

"Wow! Out of the ice, hurry, hurry, more! ”

One after the other, one after another, a series of voices rang out, and after a few moments, another sound rose and fell.

——

"It's frozen, the water in the bamboo tube is frozen!"

——

"It's a clump, the ice in the jug is clumped!"

——

"It's completely condensed, and you can't take it out!"

"There is indeed a lot of water and saltpeter, more than that, and you have to move fast." The prefect summed up the experience.

The big man in the group with him nodded hurriedly: "What the adults said is extremely true." ”

"I didn't expect that when saltpeter melts, ice cubes can be generated!" The prefect sighed: "So many doctors haven't discovered this secret!" ”

The master bookkeeper held his breath and straightened his waist: "Forget it, forget it, those quarrymen who mine saltpeter, I'm afraid they will be annoyed!" ”

"If you can be sure that the melted saltpeter can be reused, then you don't have to worry about the dog days in the future!" Looking at the main book, the prefect is another sentence "The price of saltpeter is not high, not to mention that the average person can afford it, at least the developed industrial chain will not be much high-end, when the average person is in urgent need, it can be consumed, if there are fewer people who die of heat in summer and autumn, then, this ice-making matter will become a major event for thousands of households!" ”

The main book was overjoyed: "Xuewei, this little girl, has made a great contribution again!" ”

The prefect unconsciously raised his eyebrows: "If saltpeter can really be used again, this time, she will definitely get a lot of rewards." ”

It is very rare for an official to think about problems based on the people, and it is even more difficult for those who can remember their merits after thinking about the people.

The two adults suddenly found that Ding Xuewei had disappeared.

At some point, her voice was gone!

With a turn of his gaze, he caught the figure, and unconsciously, the two approached.

“！”

“！”

A roar every day, begging for tickets, asking for collections...
