The cannon fodder through the book will live to the end

The most urgent thing is to test it first to know whether the bitter nitrate works well and whether it can make ice.

When he arrived at the cinnabar courtyard, Tao Anran saw Qu Zhishui open a small drawer in the upper corner of the traditional Chinese medicine cabinet, and took out the bitter nitrate tightly wrapped in oil paper.

Qu Zhishui put the bitter nitrate on the table, unwrapped the wrapped oil paper, revealing the white particles inside.He asked: "Princess, is this the saltpeter you are looking for?"

Tao Anran stared wide-eyed, looking serious.But in fact he didn't see anything.After all, he had never seen saltpeter.But just try it out.

He looked around and ordered, "Bai Lu, go fetch a basin of water."

A basin of water was brought, Tao Anran poured all the bitter salt into the basin under the watchful eyes of several people.The water in the basin did not react at first, but condensation soon appeared.The temperature in the basin began to drop, and some thin ice crystals began to appear.

Tao Anran was overjoyed, he was 100% sure that this was the saltpeter he was looking for.

Before all the water condensed into ice cubes, Tao Anran said urgently: "Hurry up, Hanlu, go and buy all the bitter nitrate on the street."

Others were also surprised by this phenomenon. After hearing Wang Hao's words, they realized that this bitter nitrate can play a big role in this hot summer.Han Lu only had time to respond, and ran out in a hurry.He wants to take people out to buy bitter nitrate.

Qu Zhishui looked at the thin ice in the basin and was amazed.He only regards bitter nitrate as a medicinal material, because it is cold in nature and slightly poisonous, so every time he uses it, he is careful and only takes the fine powder.Unexpectedly, putting so much bitter nitrate in water can freeze.This was really an eye-opener.

Dang Gui was also surrounded by the water basin, seeing the cleanness of the ice cubes in the basin, he couldn't help asking: "Master, is this ice cube edible? It looks so clean!"

Tao Anran heard this, but had no time to stop it.I heard Qu Zhishui say: "Danggui, where did you memorize your medical books? Let me ask you, what was put in the basin just now? How much?"

Dang Gui replied obediently: "Back to the master, there was bitter nitrate in the water basin just now. It's about four or two weights."

With a solemn face, Qu Zhishui continued to ask: "Then what is the medicinal property of bitter nitrate, and what is the usual dosage?"

When Dang Gui heard this, she also knew that she had just said nonsense.But the master looked serious, so he had no choice but to reply: "Bitter nitrate, bitter in taste, salty, cold, and slightly poisonous. It is mainly used for breaking firmness, diuresis, detoxification and swelling, etc. When using it, you can take three qian pills for oral administration, or an appropriate amount. External application."

Qu Zhishui nodded, and then asked: "Since you know all about it, why did you ask me just now. Now tell me, can the ice cubes made by bitter salt be eaten?"

Danggui lowered her head, and carefully replied: "Master, I was wrong. Ice cubes made of so much bitter nitrate cannot be eaten."

Qu Zhishui's face softened slightly, and he sighed: "Danggui, you have also studied medicine with me for several years, and you have memorized a lot of medical books. When you encounter some small things, learn to think for yourself, don't always think about asking why. Teacher. What if the teacher is not by your side one day. Forget it this time, and next time, the teacher will punish you for copying books."

Dang Gui replied in a low voice, "I understand."

Tao Anran looked at this master's disciple, so it was not easy for him to interrupt.It wasn't until the two of them finished their conversation that he said, "Although the ice made directly cannot be eaten, we can put a bowl of water in the ice, and then the ice formed by the water in the bowl can be eaten." ."

Speaking of this, Tao Anran thought of popsicles.Popsicles are almost the same principle.Put water in ice, even if there is something in the way, the water will quickly turn into ice.

Tao Anran looked at Danggui who was still a little depressed, and comforted him: "Danggui, don't be unhappy. After Hanlu buys the bitter nitrate, I will treat you to a popsicle."

Dang Gui raised her small face, she didn't feel sad immediately, only curious.He quickly asked, "Princess, what is a popsicle? Is it delicious?"

Tao Anran smiled, sure enough children are foodies!He replied: "This will be kept secret for now, and you will know when you eat it. I will go back and make some preparations, and I will send it to you when the time comes."

After he finished speaking, he took his leave and left Dansha Courtyard, and returned to Xueji Courtyard.

Back at Xueji Courtyard, Tao Anran immediately asked Bai Lu to prepare various fruits and milk, some of which were peeled and cut into small particles, and some were manually squeezed into juice.Of course the most important thing is to make some popsicle models.

You don't need to make a special model, you can directly use a bamboo tube or a teacup, or a cup.The difference lies in the thickness of the surface in contact with the ice, the thicker the ice, the slower it will freeze.

And there happened to be a set of bamboo and wood teacups in the Xueji Courtyard. I don't know what kind of bamboo it is made of, and it smells like bamboo when brewing tea.Tao Anran likes to use it to drink hot tea in winter.Of course, the most important thing is that the wall of the cup is smooth and not thick.As long as it is matched with a few small sticks, it is just the right popsicle model.

Han Lu soon came back with bitter nitrate.But not much, about two or three catties.But it is more than enough to use now.

He couldn't wait to ask someone to prepare a large basin of water, and pour some bitter nitrate into it.Then put the cups of prepared popsicle solution into the water, and put a few bowls of water directly in the empty space.

Tao Anran waited by the water basin until the water in the bowl froze, and the popsicles in the teacup also succeeded.After the popsicle is unmoulded, it looks like a success.

Tao Anran took out the ice cubes in the bowl, ground them into fine ice, and added the prepared jam and fruit cubes, and a fruit smoothie was ready.

Good food needs to be shared with others, Tao Anran asked to send two popsicle smoothies to Dansha Yuan.He will share the rest with Xiao Jingyu.And he knew that Xiao Jingyu didn't like the hot weather either.

It doesn't take long to put the popsicles out after they are taken out.Moreover, Tao Anran hadn't seen Xiao Jingyu since the morning.It hasn't rained recently, and his heart has been anxious and busy with this aspect.So Tao Anran decided to personally send some popsicles and smoothies to care about.

In Mo Yuntang's study room, the atmosphere was not very good.Today was a peaceful day until Qian Mancang returned home in a hurry and brought bad news.

Xiao Jingyu lowered his voice and said, "Say it again, what happened to Jiangnan?"

Qian Mancang replied with a tired face: "Floods have occurred in the south of the Yangtze River. Since this spring, there has been abundant rain in the south of the Yangtze River. In May, it has been raining continuously. Then, the section from the Yellow River to Yingshuikou broke the embankment. The subordinates just came from there. On the way back, I saw that the farmland and houses were submerged, and the affected area may be more than three or five counties."

Xiao Jingyu endured it, but finally couldn't hold it back, and raised his hand to pat the table.He said angrily, "What are those officials doing? Since it's raining continuously, don't you know how to reinforce the embankment earlier?"

Qian Mancang didn't speak, and let the prince vent.It's natural to vent anger when you get this kind of news.If the lord saw the flood with his own eyes and the victims were everywhere, he might not only say a few words, but he might kill people with a knife.

Fortunately, Xiao Jingyu quickly controlled his temper.Qian Mancang took advantage of the situation and continued, "When I was halfway back, I heard that the imperial court had already made arrangements for the waterlogging in the south of the Yangtze River. It is said that it was arranged for King Liang to go straight to the south of the Yangtze River with the relief money and grain."

Xiao Jingyu nodded and had no objection to this arrangement.Among those in the imperial court, sending Xiao Jing to resign was a way of expressing the importance of the royal family.But this time things are done well, he can also gain the reputation of the people in the south of the Yangtze River.Just see how far he can go.

It's just that the imperial court distributed relief silver and food to the south of the Yangtze River. If there is a severe drought in the northwest after that, the imperial court may not have enough relief silver and grain.

Xiao Jingyu then asked, "Then how much food did you purchase this time?"

When this topic was mentioned, Qian Mancang sighed and said: "I originally brought enough silver and goods, and it was not a problem to buy some food. But it coincided with the flood, and there was a shortage of food in the surrounding area. Where there is food, the price has been rising all the way. The amount of food was already five or six times the usual amount. Therefore, the subordinates tried their best to only buy half of the expected food. And..."

Xiao Jingyu frowned, "And what? Why are you hesitating."

Qian Mancang hurriedly replied: "And without permission, my subordinates used the princess' share of the past two months without permission. Only in this way can I buy half of the food."

Xiao Jingyu fell silent for a while, he didn't expect this to happen.This time, we only bought half of the expected food, and we don't know if we can pass the current barrier.However, no matter how much the concubine's share is, he will never use it, and only leave it to him as private money.But this time the situation is special, he can understand.

Xiao Jingyu thought for a while and said: "Put the food in a safe place first. As for the share of the princess, it will be recorded in the account first, and then given to the princess when there is surplus money. If the princess asks, the king will explain it. This time the situation It's special, but it's best not to use the princess' share in the future."

Qian Mancang nodded, making a note in his heart.He is essentially a businessman, and he values ​​credibility the most.It is also a kind of psychological pressure for him to use the princess's money without his consent.Now that the prince is the guarantor, he will not face the princess shamelessly.

Tao Anran took the food box to Moyun Hall, and went all the way to the outside of the study without any hindrance.Someone was waiting outside the study, and when they saw him coming, they immediately knocked on the door and shouted: "My lord, my concubine is here."

Soon he heard, "Come in."

Tao Anran entered the room with the food box, but she was not ready to say anything.He saw not only Xiao Jingyu alone in the study room, but also Qian Mancang, whom he hadn't seen for a long time.Unexpectedly, Qian Mancang was also here. Fortunately, he brought enough popsicles and fruit smoothies.

But when he saw the money in the warehouse, Tao Anran couldn't help thinking that there hadn't been any new taels in his big cash box for a long time.When I saw him this time, I probably came to give myself a share.

So after being greeted by Qian Mancang, Tao Anran said without hesitation: "You are back, so my share has also arrived. It should be two months."
