When he returned to the Li Mansion, seeing that Zhang Bao had not returned, Wei Hong hurriedly sent Zhao Hu to look for him.

As soon as Zhao Hu left, Li Ruohua's ashamed little face immediately became arrogant: "Wei Hong, what I said today is indeed something I did inappropriately, but how can you make me unable to get off the stage in front of my subordinates?" Where do you want me to put my face? What authority will there be in the future to discipline the servants in the house? Forget it now, and never act like this again in the future. ”

No matter how big the mistake of the master is, it is not something that the servant can point fingers at, which Wei Hong can understand: "Then make an agreement between the two of us, as long as the second miss does not do something worrying in the future, Wei will save face for the second miss in front of outsiders." As he spoke, Wei Hong stretched out his little thumb, meaning to pull the hook.

Li Ruohua looked at Wei Hong's little thumb, her little face showed a touch of redness, hesitated for a moment, and still stretched out her crystal clear little thumb to hook up with Wei Hong.

At this time, it happened that a little maid was passing by, Li Ruohua hurriedly retracted her hand, her little face was red and dripping blood, and she whispered: "I'm leaving......" and fled with lotus feet.

Looking at Li Ruohua's Qianqian's back, Wei Hong sighed in his heart, although his surname is spicy, he is just a woman after all.

Wei Hong chuckled and shook his head, and went directly to the 'workshop' next door. With Zhou Dali's help, the speed and quality of the project have been greatly improved, and at this rate, the first batch of sewing machines can be built in a small and a half months.

Zhou Dali handed Wei Hong a glass of water, and kept wiping the sweat on his body with a hand towel: "Son, in order to hurry up the work, we burned all the ten forging furnaces, and the temperature in this room is surging upward, it's really hot, why don't you go out first and cool off." ”

Wei Hong only stood here for a while, and the sweat on his body soaked his clothes, and the sweat flowed out along the cuffs. Looking at the sweaty craftsmen in front of the forging furnace, Wei Hong summed it up in his heart: "Now that the weather is hot, the temperature here is even higher, we have to find a way to cool them down. ”

Zhou Dali wiped his sweat from beginning to end: "How do you cool down?" Or take a break in shifts? ”

"That's not good, we have to drive out the first batch of sewing machines before Boss Li comes back, if we take a break in shifts, there will definitely not be enough time." Wei Hong pulled his sleeve and wiped the sweat on his head, thought for a moment, and said: "Vigorously, where is there ice making in Hangzhou City?" ”

"There's one, but it's not cheap. In the hot summer, some big families are willing to spend money to buy ice, if we use ice to cool down the craftsmen, isn't it a little too ......" Zhou Da Da Dou didn't know a few words, and his language organization skills were not good, and he was stuck in the middle of the words, and his old face was red, and finally he wanted to break his head and come up with a 'big material', which was relieved.

If you use ice to cool down the craftsman, it is indeed too luxurious, there is no such thing as refrigerator cold storage, and there are no chemical preparations, if you want to make ice, you can only rely on natural ice caves, which is very rare in the southern ice caves, and if you have an ice cave, you can also become one of the rich people by selling ice in summer.

Wei Hong thought about it, and suddenly his eyes lit up: "It's too expensive to buy ice, but we can make it ourselves!" ”

"Make it yourself?" Zhou Dali was confused. In my impression, there are only two ways to make ice, one is to freeze naturally in winter, and the other is to use the low temperature of the ice cave to make ice. But now that the conditions for both are not met, how can Wei Gongzi make ice?

Wei Hong's chemistry is not good, but the basic common sense is still known, there are many ways to use chemical reactions to make ice, the simplest of which is that saltpeter dissolves in water, absorbs a lot of heat, and can make water fall to the freezing point.

The use of saltpeter to make ice was first discovered in the late Tang Dynasty, and now it is the early years of the Tang Dynasty. After a brief sorting out of his thoughts, Wei Hong's slightly smiling expression looked quite mysterious: "Dali, where is there saltpeter around here?" ”

"There is a long green mountain north of the city, and there is a lot of saltpeter on it, what does the son want saltpeter?"

Wei Hong just smiled mysteriously and didn't answer, letting Zhou Dali continue to supervise the work. Wei Hong ran back to the Li Mansion as fast as he could, asked Wan Niang for fifty taels of silver, and rushed to the mansion non-stop, and bought the mining rights of Changqing Mountain with fifty taels of silver. In these years, the barren mountains are not worth much, and the reason why Wei Hong bought the mining rights is entirely for the sake of insurance, so as to avoid others from discovering the secret of saltpeter ice making, and also going to Changqingshan to mine saltpeter. As a professional businessman, Wei Hong has a keen sense of smell and long-term vision that ordinary people can't reach, if Changqingshan contains a large amount of saltpeter, he can earn a lot of wealth just by using saltpeter to make ice.

After buying the mining rights, Wei Hong took Zhou Dali and went straight to Changqing Mountain. On the way to Changqing Mountain, Zhou Dali was always confused: "Childe, what do we want that thing for?" ”

In the face of Zhou Dali's questioning, Wei Hong didn't answer, he was really annoyed by the question, so he casually threw out a sentence: "That's not saltpeter, it's silver with white flowers." ”

Zhou Dali was the one who had dealt with Wei Hong in business, and immediately thought of trading: "Silver? Who are you going to sell to? ”

Wei Hong chuckled: "Sell? Even if someone kneels down and kowtows to me in the future, begging to buy it, I won't sell it! ”

Zhou Dali's eyes widened, and he couldn't close his mouth in surprise. My mind is full of question marks and exclamation marks. Wei Gongzi's ability Zhou Dali knew, but this word had an amazing effect, which really made Zhou Dali deeply experience.

What Zhou Dali was thinking in his heart, Wei Hong didn't know, and he didn't have the heart to know, now Wei Hong's mind was full of silver ingots with white flowers, Wei Hong sighed: "In the end, it is the Heavenly Empire, and it is not an exaggeration to say that it is gold everywhere!" ”

According to Zhou Dali's guidance, Wei Hong soon came to the place where saltpeter was collected, and chiseled a thin layer of rock wall above, which was a large amount of saltpeter, and the huge reserves made Wei Hong excited.

In order to make the ice as soon as possible, Wei Hong ignored Zhou Dali's obstruction, rolled up his sleeves and went into battle in person, and the two worked together to fill the carriage in only one hour. On the way back, Wei Hong was in a very good mood, sitting in the carriage, crossing Erlang's legs, humming a little song: "Today, we are ordinary people, I am really happy......";
