"Create ice cubes? Your Highness Sean, you hired a water magician?" Sophia looked confused.

Water magicians can create ice cubes, like Vivian.

However, making ice cubes requires a lot of magic power, and ice cubes cannot be sold at a high price, so few water magicians are willing to make large quantities of ice cubes, and only occasionally make some and sell them to nobles who are not short of money.

But what does the water magician’s creation of ice cubes and saltpeter have to do with each other?

Sophia waited quietly for Sean to continue.

…

"No, we can make ice cubes without the involvement of a water magician. The answer is to use saltpeter." Sean answered.

"But Your Highness Sean," Sophia raised her hand: "Isn't saltpeter used to make gunpowder?"

"It can make both gunpowder and ice, so saltpeter is a treasure."

As Sean explained, he ordered the Silver Hand recruits to find an iron basin and a large wooden barrel.

The wooden bucket is a bucket used by residents in the town to hold drinking water. It is about half the height of Sean and about one meter in diameter.

Sean asked two soldiers to fill the barrel with a quarter of water, and then put saltpeter into the water.

…

After the saltpeter dissolved in water, it began to absorb a large amount of heat. The two soldiers also found a large wooden stick and stirred continuously to speed up the dissolution of the saltpeter.

But Sean still disliked the speed of saltpeter dissolution, so he secretly used magic power to control the violent movement of water molecules in the bucket to speed up the dissolution.

In just five minutes, a layer of fine water droplets appeared on the outer wall of the barrel, white water vapor also appeared on the water surface inside the barrel, and ice slag gradually began to condense on the water surface.

At first, Sofia still didn't believe that saltpeter could make ice. If saltpeter could make ice, then this mineral must have been famous a long time ago. How could it be unknown now?

But seeing this scene, Sophia opened her mouth in surprise.

What His Highness Sean said is true! Saltpeter can indeed make ice!

…

She stepped forward and touched the wall of the barrel covered with water drops. Her tentacles were extremely cold. Sophia couldn't help but exclaimed:

"I didn't expect that saltpeter melted in water can achieve such an effect! No wonder, Your Highness Sean, you want to collect saltpeter on a large scale. If you can produce ice cubes in large quantities, this will be great news for people in the hot summer!"

At the same time, Sofia also asked curiously: "But Your Highness, how do you know where the saltpeter is and how it can be used to make ice?"

Saltpeter has never appeared in the Principality of Lane before. Her father Olga dug the saltpeter mine behind the coastal plateau according to Sean's instructions. How did His Highness Sean know the specific properties of saltpeter?

"Of course it was guided by the God of Light." Sean said casually, and then continued: "Okay, let's try making ice cream!"

At the same time, Sean also said to Windsor: "But this is the first time to make it. The raw materials are not enough and the taste is not up to expectations. You have to be mentally prepared."

"It's okay. I just didn't expect ice cream to be made in such a simple way! I thought ice cream was a high-tech product from the Middle Ages!" Windsor laughed.

Seeing that Sean had made ice cubes, the steps behind making ice cream were very simple. Windsor just didn't expect that the ice making process was so simple.

...

Sean asked the Silver Hand recruits to go to the castle kitchen to get some milk powder, sucrose and glutinous rice flour, put them into a clean iron basin according to the proportion, add water and stir.

It is worth mentioning that cane sugar and glutinous rice flour are both luxuries in the Principality of Lane. If you want to sell ice cream on a large scale in the future, it would be better to switch to honey and corn flour.

After mixing, Sean put the iron basin into the wooden barrel that was almost freezing.

After a while, when ice forms in the basin, the "ice cream" is ready.

Although the thermal conductivity of the iron basin is very good, the whole process is just a heat transfer process, and Sean can't do anything. The freezing time in the iron basin is too slow.

After Sean waited for 5 minutes, he saw that there was no sign of ice condensing in the iron basin, so he simply gave the ice-water mixture to Windso and Sophia without waiting:

"When it freezes completely, it will be ice cream, but it will take a long, long time. You guys should try these first. Now you can also call it a 'cold drink'."

Sofia took the "cold drink" and tasted it. It was ice cold. It felt good to drink it in the summer.

"It feels very good to drink this beer in the summer... Of course, for mercenaries, they prefer cold beer."

"You have reminded me!" Sean's eyes lit up: "We don't have to stick to making ice cream, cold beer, cold watermelon and other fruits can also be sold... By the way, Sophia, are you willing to follow

Shall I go to Port Kapur with you? All your expenses on the way will be borne by me."

Faced with Sean's sudden invitation, Sophia was surprised, but she immediately replied: "Of course I am willing!"

"Okay then, go and prepare. We will set off in two days."

"Okay, Your Highness Sean. I'll go back first!" Sophia said goodbye to Sean.

...

After Sophia left, Windsor said to Sean: "Sir, this is not the only ice cream in my memory, there is a better one that should have eggs and cream in it."

"Oh, that's another way to make ice cream. We'll try it slowly in the future. Windsor, you go ahead and work on it. I'll be fine here alone."

"Okay, sir." Windsor said goodbye to Sean without asking any questions and left.

But Windsor is indeed very busy. He is going to Port Kapur tomorrow and he still has a lot of things to prepare.

After Windsor and Sophia left, Sean used saltpeter to make some ice cubes and threw them into the [Dimensional Backpack].

With the help of saltpeter, ice cubes that originally required a lot of magic power to be made can now be made with very little magic power.

These ice cubes can be saved for emergencies.

…

After finishing his work, Sean returned to the castle study and started reading, quietly waiting for nightfall.

As night fell, after dinner, Sean went to the basement. This was the time he had arranged to communicate with Khadgar by passing notes.

But today is special. Sean broke through level 30 today, and a lot of big things happened in the territory. It was difficult to explain it clearly with a note, so Sean wanted to send the message that he wanted to talk to Khadgar face-to-face through the portal.

That end.

Khadgar also quickly emerged from the portal and came to Sean.

"My lord, congratulations on reaching the Silver level!" Khadgar congratulated Sean.

"Khadgar, I broke through the Silver level and joined the mage profession. Can you teach me how to have the 'Raven Form?'"
