Early in the morning, Ouyang Rong came to Jiangzhou lobby.

Go directly to Yan Liulang and ask directly:

"Where is the batch of Burning Sky Dragon Oil that Wang Caozhi left behind before he left?"

Yan Liulang immediately replied:

"I reported it to the Ming Dynasty and stored it in the Governor's Mansion. A few days ago, County Magistrate Diao came and took a batch back, but there were too many and there was still a batch that was not taken away. We are going to transport it back slowly."

The Shuangfeng Peak was sealed off in the name of water control, and before the giant Buddha was completed secretly, Wang Caozhi, who went to ask the eminent monk of Donglin Temple to pretend to be dirty, brought back a batch of sky-burning dragon oil from Longcheng County for use. Later, the giant Buddha was successfully placed on the ground without any incident.

In any unexpected conflict, the Burning Sky Dragon Oil will not be used and is currently being transported back to Longcheng County for storage.

Ouyang Rong asked: "How many barrels are left?"

"Nine barrels." Yan Liulang accurately reported the number.

Yan Liulang saw his Mingfu counting his fingers and murmured: "It should be enough. If it's not enough, I can still make some..."

"What's enough?" he asked curiously.

Ouyang Rong shook his head: "It's okay. Don't transport it away yet. Put it in the governor's house and wait for my follow-up instructions."

"Yes, Mingfu."

Ouyang Rong turned his head and glanced into the distance.

Yan Liulang followed his gaze and found that it was over at Prince Xunyang's Mansion...

After giving instructions to Yan Liulang, Ouyang Rong took the car to Prince Xunyang's Mansion.

The remaining Burning Sky Dragon Oil in Dragon City was all used by the Jade Goddess and others to blow up the Di Gong Gate during the ribbon-cutting ceremony.

After it was first seized, it has been stored in the Longcheng County Government Office. The quantity is so large that it has not been used up until now.

But it doesn't matter if you use it up.

Ouyang Rong knew that the method of making the Burning Sky Dragon Oil was passed down from the Jade Goddess. In addition, the Jade Goddess and the Liu family had secretly borrowed it from the Guyue Sword Shop to make it. Some craftsmen remembered the recipe.

Also out of curiosity, he had specifically researched before. Among the ingredients for making Burning Sky Dragon Oil, Ouyang Rong discovered a very familiar raw material - saltpeter.

This is the material of gunpowder. In a sense, the burning dragon oil that can be exploded and ignited has the same goal as gunpowder... In addition, saltpeter can actually make ice. The method is simple, easy and low-cost, but it is only incidental.

It seems that the alchemists of this era have already invented this thing in the process of alchemy, but they regard it more as a magical thing, and even supplement it with Qi refining materials to make current products such as Burning Sky Dragon Oil.

Wait for strange things.

Ouyang Rong nodded lightly.

The carriage arrived at Prince Xunyang's Mansion. After entering, he went directly to his junior sister's boudoir to discuss with her the birthday ceremony in a few days.

When he arrived at the place, he found that there was no one in the courtyard. Ouyang Rong asked the maid and got the answer. He turned and walked to the back garden. A quarter of an hour later, he saw Li Xian's family and his junior sister in a pavilion facing the lake.

Also among them.

A group of people were admiring the scenery at the waterside pavilion, tasting fresh fruits and vegetables, and there were several bottles of wine and jugs exuding white mist on the plate.

When Ouyang Rong arrived, everyone warmly welcomed him.

"Everyone happens to be here, there is something..."

While Ouyang Rong was speaking, Li Dalang grabbed his sleeve and pulled him into the waterside pavilion.

The latter enthusiastically entertained me: "Liang Han, try this pot of ice wine. It's really refreshing."

Ouyang Rong couldn't help but take a closer look.

I found that the fruits and wine were all iced, no wonder they were "foggy", they must have been taken out not long ago.

Now that the weather is getting warmer and we are about to usher in early summer, eating ice cream is really delicious.

But after he reacted, he asked with a puzzled expression:

"Where did all this ice come from?"

Li Guoer looked at it as usual and said, "Ice cellar, otherwise where would the ice come from in this late spring?"

Xie Lingjiang explained: "The ice cubes in the ice cellar are all cut and stored in winter, and are reserved for summer use."

Ouyang Rong stared at the ice cubes, thoughtfully.

It seems that the imperial court of the Great Zhou Dynasty did have a special organization for storing ice, called the Ice Well Service. In addition to storing ice, there were also iced drinks, fruits and vegetables for the royal family and high-ranking officials to enjoy.

However, the current ice storage can only rely on manpower to collect ice in winter, which is inefficient. The production and preservation process is very cumbersome and costly. Therefore, among the people, only wealthy nobles can afford it. Ice is a luxury product more expensive than gold.

However, Xie Lingjiang, Li Guoer and the others were accustomed to this thing.

At present, there are no more than three families in Xunyang City who can afford ice. Huaiye Lane House certainly does not have one, and Xunyang Palace is one of them. This is the ice that the imperial court regularly gives to the palace as usual.

When everyone saw his reaction, they thought he liked ice cubes.

Xie Lingjiang said: "Elder brother likes it, I will have some sent over tomorrow."

Li Xian also said: "Why don't we let the craftsmen go to Tanlang's residence to open an ice cellar, which will also be convenient for storing ice. From now on, half of the ice cubes in the palace will go there."

The corners of Li Guo'er's lips twitched slightly: "Ouyang Lianghan, your study room is called Yinbingzhai. How can we do it without ice? This is not right."

Ouyang Rong said nothing, stretched out his hand to touch the body of the cold wine pot, and suddenly said:

"Is the ice cellar in the palace big? Where is it located?"

Everyone was stunned.

Ouyang Rong left the fruits behind without tasting them at all, and turned around and went out:

"Take me over there and have a look."

After receiving his father's look, Li Dalang followed and led the way.

Li Xian was a little curious and shouted: "What did Tan Lang want to say just now?"

"We'll talk about it later."

Ouyang Rong waved his hands from behind.

…

Ouyang Rong visited the ice cellar of Prince Xunyang's Mansion in the morning.

After leaving, go directly to Pei Shisanniang.

In the woman's house, in the hall.

"What are your orders, Master?"

Pei Sanniang came in with some joy and brought tea and water to Ouyang Rong.

Ouyang Rong rarely came to her residence.

Moreover, after the governor's office meeting a few days ago, after Wang Caozhi and others left, Ouyang Rong told them to rest quietly for a few days and wait for his aunt's birthday ceremony and the Buddha's celebration ceremony.

So I probably haven't seen anyone in the past few days...but today, I came to see her.

Pei Shisanniang had some random thoughts,

But Ouyang Rong's words brought him back to reality:

"Do you know where the ice is?"

"Ice? Isn't it only in winter?"

Ouyang Rong shook his head: "In addition to ice harvesting in winter, where do the ice cubes in the ice cellars in the imperial court come from? Is there any other source, or is there any method of making ice?"

Pei Shisanniang was confused: "How to make ice?"

He stared at this well-informed and beautiful woman and asked, "Well, is there any?"

Pei Shisanniang suddenly nodded: "Yes."

Ouyang Rong turned around: "What?"

"I heard that some gods on the mountain can turn water into ice, so they should be able to make ice too."

Ouyang Rong's mouth twitched and he waved his hand:

"This doesn't count. There is no other general method, right?" "Yes." Pei Shisanniang was confused: "Master, is there any other method?"

Ouyang Rong walked around in the hall and muttered: "Have you not discovered the method of making ice with saltpeter yet... I didn't expect that I would have to do such boring things one day..."

Under Pei Shisanniang's confused gaze, he turned around and asked calmly: "Is ice expensive?"

Pei Shisanniang said seriously: "Expensive, very expensive, but if the master likes it, I can get her, but the number may not be too much..."

"I'll get it out for you."

Pei Sanniang was a little shy like a little girl: "What, sir, do you want to be here?"

She looked around at the terrain.

Ouyang Rong was confused: "What are you talking about? I mean making ice."

In fact, he understood it instantly, and said with a serious face: "I will teach you a method, and you can have as much as you want in the future."

Pei Shisanniang stopped her smile, looked more serious, and asked: "Where did you get it from? The temperature is so high now."
