The Lone Star of the Tang Dynasty

Although this question is not a mystery for the ages, it has caused a lot of waves in Li Er's heart. His eyes widened as he looked at the wooden door on the ground, his heart full of doubts.

Empress Eldest Sun, Du Ruhui, and even Li Junxian, who had been standing quietly, also focused their eyes on the wooden door, as if they were expecting something.

The

maids Mian'er and Ying'er, who were following behind Li Changge, looked at everyone's expressions, and the corners of their mouths involuntarily hooked up a smile. They seemed to have foreseen what was going to happen next, and they felt a little smug in their hearts.

Regarding everyone's reaction, Li Changge was not surprised. He clearly remembered that when Mian'er and Ying'er first saw this ice cellar, they were also stunned.

"Childe, is this cold storage used to store ice cubes?" Li Er couldn't help but ask, his voice revealing a bit of disbelief. Because in his cognition, ice cubes are naturally formed, how can they be stored artificially?

Li Changge looked at Li Er, smiled slightly, shook his head and said, "Of course it's not used to store ice cubes." This cold storage is used to store other things. As he spoke, he stretched out his hand and pointed, "Meat, vegetables, melons and fruits...... And so on, you can save it here. Ice cubes, on the other hand, are made and then put in. "

As soon as Li Changge's words fell, Du Ruhui, Empress Changsun, Li Junxian and Li Shimin were all stunned. Their eyes widened and they looked at Li Changge as if they were looking at a monster. Ice cubes, which God froze, how could they be artificially made? This simply subverted their cognition.

"Childe, how is this possible?" Empress Eldest Sun couldn't help but ask, her voice revealing a bit of surprise.

"What means did you use to do this?" Du Ruhui couldn't help but ask, his eyes looking at Li Changge were full of curiosity.

Even Li Junxian, who had always been silent, couldn't help but blurt out: "Impossible! Ice cubes are a godsend!"

"What's impossible?" Li Changge looked at everyone and said lightly, "Using the saltpeter method, the matter of making ice, and the small skill of carving insects." "

"The method of saltpeter?" Li Er and the others were stunned when they heard this, they looked at Li Changge, as if they were waiting for his explanation.

"Isn't saltpeter a medicinal material for alchemy?" asked Empress Eldest Sun suspiciously, "You can also make ice with saltpeter?"

Li Changge looked at everyone's shocked expressions, and couldn't help but feel a little funny in his heart. He had expected such a reaction from these people. For him, these things are all too commonplace. But for the sake of everyone getting along well, he decided to explain it to these people.

"A certain amount of saltpeter is used to carry out a chemical reaction through a set of simple equipment, and this chemical reaction is a relatively rare endothermic reaction. As a result, it can take away the heat from the water, causing the moisture to keep the temperature lower, and finally until it freezes. Regular storage of saltpeter ice in the cellar can maintain a low temperature environment for the storage of perishable foods such as meat. Of course, you can also make dim sum in the summer,......," Li Changge explained slowly.

With his explanation, the expressions of Li Er and the others gradually changed from shock to abruptness. They looked at Li Changge's eyes full of admiration and curiosity. It is truly impressive that this young man knows such a magical skill.

"What is a chemical reaction, and what is an endothermic reaction?" Li Er asked curiously, "Can it actually suck away heat? Is this an immortal technique?"

Li Changge couldn't help but be a little speechless when he heard this. He glanced at Li Er, shook his head and said, "This is not some kind of immortal art. Both chemical reactions and endothermic reactions are phenomena that exist in nature. It's just that you haven't been exposed to it before. "

As he spoke, he looked back at Mian'er, "Mian'er go get some ice cream." "

"Childe, it's only early spring, and you said that eating ice cream hurts ...... stomach," Mian'er said with some concern when she heard this.

"It's fine, not once in a while. Go ahead. Li Changge waved his hand.

"Yes, Childe. Mian'er answered, stepped forward and squatted down to open the wooden door on the ground.

A dimly lit passage slowly opened, revealing a deep staircase below. The little maid's figure was light, and she walked carefully down the stairs.

At the same time, streams of white vapor churned out of the passage, carrying a biting chill in the face.

Li Er and the others stood at the entrance of the passage, only to feel a cold air flow sweeping over in an instant, making them shiver. They realized that the environment in the depths of the cellar was probably much colder than the outside.

It was early spring, and although ice cubes were not uncommon, such a large amount of cold air had never been seen before. Everyone was secretly surprised in their hearts, and they were even more curious about the ice-making technique that Li Changge said.

After a while, Mian'er walked up the stairs with a large wooden plate. Seven or eight small porcelain bowls sit on a wooden plate, each containing a round ice cream topped with slices of fruit of various colors, which are bright and attractively colored.

Li Changge smiled and invited everyone to the living room to taste.

There is a fire in the living room, and it is as warm as spring. Everyone sat around the fire, roasting the warm fire, and the chill on their bodies gradually dissipated.

Cotton presented the ice cream to everyone one by one.

Li Er and the others glanced at each other, and then couldn't wait to taste it. After just one bite, the sweet taste instantly blooms in the mouth, and the cold taste makes people feel extremely comfortable.

"What is this? It's so sweet and delicious!" Li Er exclaimed.

"The perfect combination of fruit slices and milk is simply a delicacy in the world!" Empress Changsun couldn't help but praise.

Although Du Ruhui and Li Junxian did not speak, their eyes were full of amazement and satisfaction.

Everyone agreed, and for a while there were continuous admiration in the living room. Although they are royal nobles and are accustomed to all kinds of delicacies, they are completely conquered by this ice cream at the moment.

Li Changge looked at everyone's satisfied expressions, and couldn't help but feel a trace of pride in his heart. He smiled faintly, and then said, "It's called ice cream, and it's a dessert I created in my spare time. It's a bit of a hassle to make, but once you get the hang of it, it's not that hard. "

Everyone nodded in agreement. They are well aware of Li Changge's talent and wisdom, and they are naturally convinced of the kind of food he created.

Du Ruhui looked at Li Changge, his eyes were full of appreciation and curiosity. He couldn't help but ask, "Childe's ice-making technique is really magical. I don't know if Gongzi has ever considered promoting this ice-making technique to Chang'an City? I believe it will be sought after by many princes and nobles. "

Li Changge was slightly stunned when he heard this, then shook his head and said, "Although Chang'an City is prosperous and lively, it is not what I wanted. Besides, the art of ice making requires the use of materials such as saltpeter, which is quite cumbersome to mine and use. I'm too lazy to bother with this god. "

Du Ruyan couldn't help but be a little disappointed when he heard this. He thought that Li Changge would use this ice-making technique to make great achievements in Chang'an City, but he didn't expect that he didn't care about it.

However, Du Ruhui also knew that Li Changge's character had always been like this, since he didn't want to do something, no one could force him. So he could only sigh helplessly, and then changed the subject.

Everyone chatted for a while, and Mian'er and Ying'er left the living room to prepare lunch at some point.

It's time for lunch in a blink of an eye, and the Datang custom is to only eat two meals a day plus supper, and normally skip lunch. But Li Changge wants to entertain everyone, and Li Shimin and Empress Changsun will naturally not refuse.

At this time, there was a tempting aroma from the back kitchen, and Li Changge said with a mysterious smile on his face: "It's almost time, please come with me." Today I would like to invite you to taste my special teppanyaki. "
