After hoarding billions of goods and traveling through the book, he farmed in another world to suppo

This ice water was made by Xiao Li using the method of making ice with saltpeter.

Put saltpeter into a wooden barrel after filling it with water. When the water starts to solidify, put the bamboo tube into the barrel. When the water is almost solidified, take it out and you will get ice water.

Xiao Li also sent a large bamboo tube of ice water to the other two carriages and whispered some instructions to them.

In this era, only wealthy families could afford ice, and they would store it in cellars during the cold winter and take it out to use in the hot summer or sell it to others at a high price.

At that time, ice would even be more expensive than rice. Ordinary people often couldn't even guarantee enough food and clothing, so how could they be willing to eat a bite of ice?

Not to mention that when you are in a hurry, in this remote countryside, even tea stalls selling water are rare. You can imagine how precious this sudden ice water is.

Everyone was not stupid. Although they were curious about how he made the ice water, no one asked him. When drinking the ice water, they acted like thieves, afraid that outsiders would discover them.

Shen Congzhou and Yu Qingshan were the calmest among them. They had both been to the capital and knew that ice could be made.

Just like the papermaking technology is in the hands of a few major families, this lucrative business can only be done by them.

The method of making ice was also monopolized by the royal family. Even if ordinary people could find a way to make ice or store ice cubes in winter until summer, they could not compete with the royal family for business.

Even if someone can really get a piece of the pie from those people, it will not last long. At the very least, he will lose his family property, and at worst, he will lose his life or even his entire family will be wiped out.

Over time, everyone knows that some things cannot be touched easily, and even family members will do so secretly.

Shen Congzhou was just surprised that the young master could even make ice, while Yu Qingshan moved from Shen Congzhou's carriage to his and sat in the driver's seat with him.

Along with him came a gourd for holding water. He drank a mouthful of ice water with great satisfaction before asking Xiao Li in a low voice, "Any more? Give me some more."

Xiao Li glanced at the old Taoist priest who was almost holding the gourd to his face, and looked at him indifferently, "No more."

"Mr. Xiao, didn't you lie to me?" As he spoke, Yu Qingshan's eyes were almost glued to the covered wooden barrel next to him.

Xiao Li ignored him and just said, "If you're not afraid of any problems after eating it, there's definitely more in the bucket."

"Huh? Why?" Seeing that he didn't stop him, Yu Qingshan simply took off the lid of the wooden barrel and looked inside.

When he saw the ice cubes mixed with the water and an unknown object at the bottom, he put the lid back on with an embarrassed look on his face. "I don't have to drink this, but why do the stones inside look a little familiar?"

As he frowned and tried to recall what that thing was, Xiao Li's extremely calm voice came from the side.

"Xiao Shi, don't you Taoists like to add this stuff when making elixirs?"

"What did you just say?" Yu Qingshan suspected he had misheard. "Can Xiaoshi make this... thing?"

He was indeed familiar with Xiaoshi. Even though they in Qingshan Temple did not have the hobby of refining elixirs, this thing could relieve heat and they would occasionally use it in the temple.

But he had never seen one as big as a fist.

The water in the wooden barrel was a little turbid, and there was floating ice on the water surface. He took a quick glance and did not recognize it.

"Otherwise, guess where this thing came from?" Xiao Li glanced at the gourd in his hand, then retracted his gaze and continued to look forward.

Since leaving Nan'an County, the carriage he was driving had always been leading the way, so he had to pay attention to the road conditions at all times, so as not to drag the horse-drawn and ox-drawn carts behind into the ditch.

"I didn't expect that this small stone could be so useful." Yu Qingshan sighed.

Thinking of what he had just said about Taoists loving to make elixirs, he couldn't help but explain, "Although Qingshan Temple is also a branch of Taoism, ever since the Taoist master passed away after taking the elixir he made, the Taoist master has strictly forbidden the disciples in the temple to make elixirs anymore.

Since my generation of disciples, few have studied alchemy, and most have delved into medicine or fortune-telling."

He spoke so confidently that Xiao Li only asked him, "Are you sure?"

He was stunned for a moment, and after a while he frowned and asked, "What do you mean, Master Xiao?"

Xiao Li felt that it was okay to keep on walking in silence, but since there was a boy who brought wealth to chat with him, he didn't mind saying a few words.

"Nothing, I just wanted to ask if you're sure?

If your master was refining the elixir without telling you youngsters, or letting others refine the elixir secretly, how could you be completely unaware of it?

After all, in my impression, no matter which branch of Taoism, they are all very keen on alchemy.

Of course, not all of them are refined with fire. Some medicines are made into pills. In your Taoism, they should also be considered elixirs, right?"

Yu Qingshan had no way to refute this, "Mr. Xiao is right. Our Qingshan Temple is mainly engaged in refining medicine and alchemy...

"That's never happened to me. My master is a man of his words. Since he's such a kind man, he certainly wouldn't come here secretly."

But what he didn't expect was that his words would be severely overturned by his master on the day they arrived in the capital.

"Really?" Xiao Li raised the corners of his lips and smiled meaningfully. It didn't look like he believed it at all.

Yu Qingshan opened his mouth, not knowing what to say, then he closed it awkwardly and leaned aside with his eyes closed to rest.

At night, Xiao Li placed an ice bucket on each carriage, told them that the ice and water inside were not edible, and then let everyone rest.

Because of the extra ice bucket, everyone got a good rest throughout the journey, both during the day and at night.

Compared to the students around them who were too hot to concentrate on reading, they all looked quite energetic, except for occasionally feeling sore all over from sitting in the carriage.

Even Bao Ge'er, who was nearly four years old, looked lively and energetic, which amazed the students who were traveling with him.

It’s not that no one was curious about why they were in such good spirits, but when they saw the indifferent look of their leader Xiao Li, a group of them were the first to retreat.

In addition, the men in their group are all tall and strong, even the old Taoist priest who looks to be in his seventies or eighties is in good spirits, which makes people dare not provoke them easily.

After all, you're unfamiliar with the place, and if you start asking people how they're able to travel so quickly, who knows if it's an ancestral recipe? How is that any different from coveting someone else's ancestral property?

In short, those who have dignity are too embarrassed to ask, while those who are shameless are afraid of their large numbers.
