What do you have that is worth embarrassment for us? However, sometimes once an opportunity is missed, it is missed. I hope you can think about it clearly. "
After Liu Er finished speaking, he left.
The refugee stood there thinking for a long time before going to find his companions.
Liu Er came to Li Qian.
This is a laboratory built by Li Qi'an. There are various things in it, including iron blocks, wood blocks, bamboo tubes, two small stoves, various large and small utensils and tools, and some various Various stones.
"Mr. Li, those refugees are not bad-hearted. They were forced to come in to gather information because their families were kidnapped by the bandits. So, I gave them a chance to see if they were willing to stay. "Liu Er reported to Li Qi'an.
Li Qian was directing Dahei to pour some crystalline things into a large vat. He nodded and said, "You are doing the right thing. You should give them a chance."
After Dahei finished pouring those things, he asked Dahei to pour most of the water into the tank.
I saw water rolling, and there were explosions from time to time.
Liu Er looked at this scene in surprise. Is Mr. Li doing something new?
After the water surface stabilized, Li Qian also put the basin of cold boiled water he had prepared in advance into the tank.
The basin floated on the water, and soon, white ice patterns began to appear on the water.
Liu Er and Dahei both widened their eyes.
As they watched intently, they saw that the water in the tank was completely frozen, and the water in the basin also began to freeze.
Liu Er looked like he had seen a ghost. Does Mr. Li know magic?
After all, it's almost June now. It's freezing in such hot weather. Who would believe it?
Li Qian also watched intently as the ice gradually formed.
It really worked.
Those crystalline things are of course saltpeter.
Salt mines originally contained saltpeter ore, so it was not difficult for him to obtain saltpeter.
He was also on a whim, seeing that the weather was getting hotter and hotter. In his previous life, he was used to living with a refrigerator and all kinds of cold drinks. How could he not get something to relieve the heat?
I thought of making ice with saltpeter.
As a modern person, how could he not know about making ice from saltpeter, but he had never tried it before. After all, there was no need to try it before, and there was no need for him to make ice himself.
At this time, Dahei touched the ice surface with his hand and put it into his mouth to suck on it a few times. new
With a cheerful look on his face, he said, "Brother Qi'an, as promised, this piece of ice is mine."
"Here, are you worried that you won't be able to eat ice in the future? Be careful not to get a bad stomach." Li Qian said.
Dahei also immediately knocked away the basin of ice.
"Mr. Li, what happened just now? How could you make ice in such hot weather?" Liu Er asked in confusion after Dahei left.
Li Qian smiled, "This is actually a natural reaction, these are things called saltpeter." He also pointed to the saltpeter, "When they dissolve in water, they absorb a lot of heat and can cool the water to the point where it freezes." Ice, to put it bluntly, it’s actually nothing.”
Liu Er didn't ask any more questions. After all, even if Mr. Li said it, he didn't quite understand.
He only knew that what seemed like nothing to Mr. Li was a huge miracle to them.
"If those refugees are willing to stay, I will let you take care of them. If not, give them ten taels of silver each." Li Qian returned to the previous topic.
Liu Er couldn't help but said, "Mr. Li actually doesn't need to treat them so favorably. Just let them go. Why give them money?"
"You were also a refugee at the beginning. As you said just now, these people are not bad-hearted. They are all forced to have no choice. Besides, if they work so hard here, they can't be in vain," Li Qian said. .
Liu Er lowered his head, "Mr. Li, I would like to thank you on their behalf."
"Go." Li Qian waved his hand, "Those bandits will come at any time, and we must make some preparations."
After Liu Er left, Li Qian looked at the saltpeter.
Then he shook his head, forget it, it would be too scary to do that thing now, let’s wait until later.
After Liu Er came out, the refugees were already waiting for him.
"Brother Liu, after some discussion, we decided not to stay." The former refugee said with his head lowered.
This was also the result of their discussion for a long time. Originally, he advocated staying, but the others were afraid that the bandits were about to come in, so they all decided to leave.
"In that case, let's go. Mr. Li said that if you leave, each person can get ten taels of silver. You wait a moment and I will get the silver for you." Liu Er said.
The refugees were all stunned.
And Liu Er had already gone to get the money.
"Why do you still give us money?" The refugees looked at each other in confusion.
