Settle Down In Tang Dynasty

When he was interrupted, he was not interested in tasting tea. Xue Langtang and Huangzhi put away the tea jar and prepared to take it back to the auditorium.

This cheeky appearance, caused Pingyang Princess do not have a deep look, but also did not say anything. Xue Lang was about to leave when Princess Pingyang suddenly said, "I almost forgot the business!"

Xue Lang quickly clasped his fist: "Your Highness, please say so." Princess

, your highness said, "the nitre you asked for, I've been asked to find it. Is the two car enough?"

Xue Langhan: "Your Highness, you have more than enough. You can't use it for several years."

Princess highness smiled: "enough is enough, only if it is not enough, even if it is unnecessary. What's the relationship between this saltpeter and the ice cellar? Why does Youyang say that you need saltpeter to build an ice cellar? "

This is a chance to put on the door!

Xue Lang laughed and asked, "Your Highness, is the ice cellar ready?"

"It has been dug for a long time, and it has been waiting for the saltpeter. Now the saltpetre has arrived, only waiting for Youyang."

princess's Royal Highness has been matched. Xue Lang said: "now that the saltpeter has arrived, it's better to hit the sun than to choose a day. Let's prepare a few large pots and smaller ones, which are thinner and smaller than the wooden ones. The coarse ones are fine and easy to use."

"Go and buy it."

Princess Pingyang gave an order to the left and right, and someone rushed to prepare. You see, in ancient times, the landlord class was so sour and sour that it could only be done by using one's mouth, and its own servants would break their legs.

The ice cellar was built in the back of the farm, close to the foot of the mountain. It was a cave. It was cool and dry. After the craftsman inspected it, he found it suitable, so he changed it into an ice cellar. By the way, it is used to be called ice well.

The party went to the farm. Xue Lang still rode his bike. His royal highness was riding a horse, watching Xue Lang ride her bike leisurely along with her horse. She looked quite curious about it. It seemed that she was very interested in bicycles. When we arrived at the farm, we did not disturb the people in the village, but went straight to the ice well.

In ancient times, ice storage was a very delicate and expensive thing. Only the powerful class could enjoy ice in summer. Therefore, at the ice well, houses are built on the ground. After the ice is stored, people should be sent to watch over.

Xue Lang asked people to move the saltpetre and the basin to the spare room, and asked people to carry water. Just as he was about to play a trick of freezing water into ice, Princess Pingyang suddenly said, "all of you, all of you, go out. Step back ten feet. If you come near without any reason, tie it up first!"

"Here it is Princess

, with a solemn face and strict command, wanted to avoid herself. Xue LAN laughed and said, "Your Highness does not need to avoid suspicion. This is just a simple chemical reaction. Speaking of it, summer is coming soon. Your highness, we might as well do the business of selling ice? If I give you skills, your highness will give you people and materials. Your subordinates will take 40% and your highness will take 60%. Will you

Princess Pingyang turned her eyes and said, "two eight! I eight you two

You're two! Your family is two!

But this can't be said. Xue Lang coughed and said, "Your Highness, there are too many of them! Technology is very important, although simple, but without the technology I provide, this business can not be done. My subordinates have been very kind. As long as 40% of the investment is made by your highness, 60% will be allocated to you. How good! That's the deal? "

Princess Royal smiled, "37! You three, I seven

Even if the beauty dimples like flowers, Xue Lang was not moved: "no! Four or six! "

This is what Xue Lang just remembered. Selling ice is more cost-effective than selling Hand-made Soap. As long as there is saltpeter, there is no cost. Every summer is the peak sales season. Nowadays, we can't store ice in every house? Besides, ice storage is a very troublesome thing. If there is a ready-made one and the cost is not too high, I believe many people are still willing to buy ready-made ones.

Xue Langyou said: "Your Highness, this business has a head. As long as you keep the technology secret, you can do it every year. Except for saltpetre, it's almost a business without capital! You can do it anywhere! Four or six, will you? "

Xue Lang lobbied Princess Pingyang. Princess Pingyang asked, "why is Youyang so persistent in making money? But the salary is not enough? "

Xue Lang shook his head and said, "if I'm the only one, the salary will be enough. However, now that there are more ah Lin, I may get married and have children and support my family in the future. Salary is not enough. Naturally, I should plan more and save money first

Pingyang Princess pondered: "this reason is reasonable."

Xue langlian said in a hurry: "it's not only reasonable, it's just to the point."

Princess Pingyang laughed and said, "yes! He fanren was appointed to be a merchant without forgetting the merchant's habits. "

this Xue Lang does not comment, Princess Royal your own decision.

everything says, with the character of Princess Royal, since promised, naturally will not change again. Xue Lang finally had a stable income to make a living, and his energy was higher.

did not let the Royal Highness avoid him. He put pottery pots in a big basin. Both of them were irrigated with water. Then he took a wooden spoon, spoon and a spoon to stir the crushed nitre into the big basin of water.

stirred and stirred, the water in the pot became colder and colder, and soon it condensed into ice.Princess Pingyang couldn't help blinking her eyes for several times, but she was calm. Besides blinking a few more times, she didn't ask questions. She only watched Xue Lang finish one pot, and then made another. After several operations, she made a lot of ice.

These pots are open. Someone took the earthenware basin with ice and baked it on the fire. The ice melted and poured out easily.

Princess Pingyang has been watching Xue Lang operate several times, but she can't help asking, "why is this? Why can water condense into ice

Because of Xue's quick explanation. According to the principle of chemistry, saltpeter contains a substance called potassium nitrate, which can absorb the heat in water when dissolved in water, so the water condenses into ice. However, the ice condensed by saltpetre water can't be eaten directly. Therefore, separate the ice in the pot with a separate pottery pot. If you eat the ice in the pot, it will be OK. In addition, the ice in the basin, when the water is poured out, the impurities can be thrown away. After boiling, the precipitated crystals can be reused

princess's Royal Highness listened with longing: "chemistry is such a magical discipline. I really want to see it. When will Youyang write chemistry for me to see? "

Xue Lang heard the pain of eggs. Chemistry is a subject that he began to contact in the third grade of junior high school in modern times. It shows that learning chemistry needs other subjects as the foundation. Princess Pingyang didn't learn the knowledge of other subjects, how to learn chemistry! So, is this a good example of lifting a stone and hitting your own foot?

Xue Lang had to perfunctorily say: "if you have the right opportunity, you will write it out to your highness."

The implication is that if the opportunity is not suitable, it will not be written, and your highness will not have to read it.

Princess Pingyang didn't know whether she knew the meaning, but nodded calmly. After a little meditation, he said, "I'll ask people to build some big ice wells to store some ice. After summer, this business can start."

"Your Highness, enjoy your cooperation."

Xue Lang happy to the Royal Highness Princess. The princess smiled and nodded, and turned back to the mansion.

She left Xue Lang and sent people to her house. First, she learned how to make ice from Xue Lang, and then Xue Lang could get rid of her body and direct on the other side. When these people started making ice, she would fill the ice well first.
