As an official, the best privilege is that the leader moves his mouth and his subordinates break their legs. Although Cheng Huaimo and the other second generations are not Zhang Nan's subordinates, after Zhang Nan assigned the task to a few of them, they still carried it out very seriously.

After all, after coming out of the military academy, the word obedience was deeply imprinted in the heads of the four of them.

Cheng Huaimo maintained order in the front yard to ensure that the people carried out the activities of taking goods and repaying money in an orderly manner, while Li Dejian chose a person who could weigh two catties and write according to Zhang Nan's instructions.

Li Chongyi and Yu Chi Baolin were on the side to help carry things, and Xiao Song was responsible for moving the big wooden barrel for Zhang Nan, after all, after adding saltpeter and water, the wooden barrel was not ordinarily heavy, and Zhang Nan, a scholar who was almost powerless, couldn't lift it at all.

However, before Cheng Huaimo's four second generations maintained order, there were some small episodes.

Cheng Huaimo and the others arrived much earlier than the people, because many things had to be prepared in advance, so when Cheng Huaimo and a few people came to the post house, Zhang Nan was preparing to make ice with saltpeter.

"Big brother, it's so hot, you run so fast, these people are so enthusiastic that they almost ate a few of our brothers alive." Cheng Huaimo fanned himself with his big hand.

Although the season is already the little tail of summer, it is still hot in the middle of summer in Qiongzhou, Zhang Nan estimates that it will be twenty-five or six degrees, plus the people surround Cheng Huaimo and them, so the heat should also be.

"It's hot, watch your big brother make a trick for you." Zhang Nan said with a smile.

"What a trick." As soon as Zhang Nan said this, the four second generations surrounded them, although they were the sons of the prince, but since they entered the military academy, let alone drinking flowers and wine, they almost couldn't get out of the gate of the military academy, so life was so boring that it was impossible to describe.

Now they find the most interesting thing is to watch Zhang Nan come up with some new things, such as the knight XV on the way to Qiongzhou.

Cheng Huaimo and Wei Chi Baolin even looked for Zhang Nan privately, hoping that Zhang Nan could get them such a car.

But after listening to Zhang Nan's offer, both of them invariably chose to give up.

Although they are the children of rich families, there is no surplus food in the Guogong family. What's more, what Zhang Nan wants is not surplus food, what he wants is simply life.

"I'm going to put on a show for you today, dripping into ice, believe it or not." Zhang Nan asked with a smile.

Several people shook their heads after hearing this, on such a hot day, not to mention that the dripping water turned into ice, it was difficult to find two places.

Zhang Nan smiled and took out a bag of saltpeter, and then stirred the water in the barrel with his hands, there are still prerequisites for saltpeter ice, one is that the amount of saltpeter must be large, and the other is that the water should be cooler.

Fortunately, saltpeter is not expensive to sell in the system, and Zhang Nan spent very few points to exchange for twenty bags.

Zhang Nan picked up the bag full of saltpeter, and then poured it all into the large wooden barrel, and then the water in the wooden barrel began to condense into ice at a speed visible to the naked eye.

The barrel then began to bubble white, and Zhang Nan, who was standing next to the barrel, suddenly felt a chill rushing to his face.

Cheng Huaimo's eyes straightened when he saw this miraculous phenomenon.

Several people walked quickly to the barrel, and then stuck their hands into the ice pile, feeling the cool smell of summer.

Yu Chi Baolin said in an unbelievable tone: "Big brother, this is really ice. While speaking, Yu Chi Baolin also grabbed the ice slag with his hand and wiped it on his face.

There is no way, who made Yu Chi Baolin the most burly of these four people? If you are big, you have a high calorie, so Yu Chi Baolin is also the most afraid of heat among the four people.

"If it's fake, how about it, I'm still okay with this hand." Zhang Nan said with a smile.

As a result, no one paid attention to him at all after Zhang Nan finished speaking, and the four second generations were eager for a fierce man to plunge into the wooden barrel to feel the coolness, and Cheng Huaimo even took advantage of Zhang Nan's inattention to stuff the ice slag into his mouth.

After Zhang Nan saw it, he felt stopped: "This thing can't be eaten, unless you want to have a loose stomach, it's better not to import this thing." ”

Saltpeter is actually potassium nitrate, and potassium nitrate itself is a laxative, how good is ice made of potassium nitrate dissolved in water?

It's better to eat this ice than to take laxatives directly.

However, it was obvious that Cheng Huaimo did not take Zhang Nan's warning to heart, but said with a smile: "Big brother, I'll just eat a little, it's no problem, a body like ours won't get sick at all." ”

After Cheng Huaimo finished speaking, he stuffed another mouthful of ice slag, Zhang Nan had never eaten what the ice made of saltpeter tasted like, but Zhang Nan didn't think it tasted much better. But Zhang Nan didn't bother to tell Cheng Huaimo anymore, there are some things, you still have to suffer a loss to remember.

Although the people seem to be crowded with people in the notice, as long as they come one by one, the things in their hands can still be solved quickly, after all, the price given by Zhang Nan is the same price as a stone of abalone, but there will be someone there who can really catch a stone of abalone? What's more, the people who caught abalone chose to find Huanghuali after changing the first batch of abalone.

After all, it is not easy to catch abalone enough to weigh enough, but the huanghuali of the three is easy to find, so Zhang Nan received Liu San's two huanghuali and a lot of abalone in the morning.

Zhang Nan looked at the quantity and felt that it was enough to create a hunger marketing. So he explained to Li Dejian, if there are still people here to exchange money in the afternoon, they will all be accepted, and as for the abalone, they will not be accepted for the time being, after all, Zhang Nan has decided to go back to Chang'an first.

Before leaving, Zhang Nan also deliberately explained that he would find a good doctor for Cheng Huaimo in advance, but Zhang Nan saw that Cheng Huaimo had eaten a lot of such laxative ice. In case Cheng Huaimo pulled out his large intestine, Zhang Nan still had to prepare in advance.

In the afternoon, Zhang Nan found a few carpenters in Qiongzhou City, split the two huanghuali pears, and Zhang Nan asked the carpenters to make all the woods into beads, and made holes and threaded them into strings.

In addition to the wood in the heart of the tree, Zhang Nan asked several other carpenters with better craftsmanship to carve a few small ornaments.

After doing all this, it was already when the sun was about to set, Zhang Nan loaded the abalone into the car, and then put the finished cultural toys in a bag, and finally hit the knight XV and began to drive towards Chang'an City.

On this trip to Qiongzhou, Zhang Nan can be said to have gained a lot and returned with a full load.
