After entering the kitchen, Xiao Wen discovered that the entire appearance of the kitchen had changed.

Not only was the floor plastered with fireproof and waterproof tiles, but there was also a road that led directly to the icehouse.

Although Xiao Wen knew that the principle behind making a refrigerator was simply to install some semiconductors in a thermostat, through the semiconductors, in the case of electricity, the heat would constantly be transferred from the low-resistance part to the high-resistance part to create cold air. As long as the high resistance part is on the outside, the low resistance part can be used to make a refrigerator.

However, the materials of the burly man weren't powerful enough. Even if Xiao Wen created the semiconductor material, it wouldn't be efficient enough. With the original generator, the refrigeration equipment had no practical value at all.

Plus, Xiao Wen already had an ice workshop, so as long as he dug a cellar, stored enough ice, and placed the food on shelves and boxes, he would be able to get a freezer that was much bigger than the double-door refrigerator.

The door to the freezer was made of wood with wool in it.

This was Xiao Wen's reminder.

After all, no one at home knew that the more insulating the materials were, the more efficient they would be in preserving the cold air.

In addition, Xiao Wen also noticed that there was a long black and grey pipe extending from the outside of the door all the way to the stove.

"Have you already made the biogas pond?" Xiao Wen asked.

Xiao Wen had always felt that cooking with firewood was a very troublesome task. Not only was the smoke large, it was also very inconvenient to control the temperature of the fire.

Thus, although there was no output of coal or gas in the area now, he found a substitute for biogas.

The skill required to create the biogas pond wasn't complicated. After searching the library's information, Xiao Wen didn't even organize the materials and directly took out the most suitable blueprints.

"Yes." Already done. Fortunately, with the help of your masons, the biogas tank will probably need another year to be completed. In addition, those that fill the biogas tank... "Night Fragrance spent a lot of our family's money." Zhou Xian said.

"Night Fragrance …" Xiao Wen was stunned and immediately understood what Zhou Xian meant.

However, he didn't expect that the big man in this world would be so valuable …

But after thinking about it, Xiao Wen understood the reason behind this.

After all, the history of manure technology, although not in the early Han Dynasty. However, manure technology was an agricultural technology after all, and it was a very low-cost agricultural technology, so the speed at which it spread was also within reason.

Therefore, even in the eyes of the large farmers, night incense was a very valuable thing.

However, things like the marsh gas tank required sufficient fermentation materials. If the materials were scarce, not only would it be unable to provide a stable marsh gas, but it would also explode after a bit of sparks appeared …

Although the power of the explosion was average, it couldn't hurt a person. But the damage to a person's San value caused by dung smearing on the wall could be even greater than the damage caused by a bomb to a person's body.

As a result, Xiao Wen didn't let Zhou Xian and Zhou Wei produce this thing on their own. Instead, he asked Zhou Xian and Zhou Wei to buy the night incense to fill up the pond as soon as it was built.

Nowadays, as long as Xiao Wen's kitchen opened the pipe mechanism, there would be a steady flow of biogas flowing out from the pipe. At the mouth of the pipe, there was also a piece of fire rope (see how people used it to ignite the gunpowder before the invention of the flintlock gun).

As long as the biogas tank gushed out, it would become a flame, providing heat to Zhou Xian and Zhou Wei as they cooked.

After looking carefully at the changes in the kitchen, Xiao Wen nodded in satisfaction.

He looked at Zhou Xian and asked, "Sister-in-law, is there anything I can help you with?"

"Mm, I always felt like I was about to get something out of this boiled water cabbage." "Try it."

Boiling water cabbage?

Xiao Wen was shocked. Before Xiao Wen left, he wrote down the Chinese cuisine and some of the foreign cuisines that he thought were delicious for Zhou Xian to study, but he didn't expect her to specialize in boiled water.

Boiling water cabbage was one of the famous dishes in the national banquet of China in his previous life. At the same time, it was also one of the best and most representative dishes in Sichuan.

Many people thought that only those with spicy and numbing flavors would be able to represent Sichuan cuisine. It wasn't spicy food, it wasn't Sichuan food. And Sister Chuan was also known as the "hot chick".

However, the existence of boiled water cabbage did not lack the faces of the non-Sichuan people who had misunderstood Sichuan Cuisine because they did not understand it well. At the same time, he also slapped the faces of the Sichuan people who felt that their hometown's dishes were all spicy and spicy.

But in reality, the boiled water cabbage had yet to appear in this world line.

Because in the original history, boiled water cabbage was created by the famous Sichuan cuisine chef, Huang Jinglian, in the imperial kitchen of Qing Gong palace. Later, the famous Sichuan cuisine master, Luo Guorong, rose to prominence and became a fine product during the national banquet.

The boiled cabbage was made with the cabbage heart of the north, seasoned with chicken soup, and then soaked in chicken oil while the soup was being poured. After cooking, fresh and light, rich and mellow, rich soup, not oily and not greasy, but refreshing and refreshing.

On Sept. 10, 2018, "Chinese Cuisine" was officially announced, "Chinese Cuisine" was ranked as one of the top ten classic dishes in Sichuan.

The main materials selected are cabbage, broth, hens, ham hooves, ribs, dried shellfish, peeled thin chicken breast, all lean pork and so on.

It could be said that boiling water cabbage, even among Chinese cuisine, was a top-notch dish.

As a top-notch old turtle, Xiao Wen had once visited Sichuan in his previous life. There was an invitation from a friend and they had a boiled cabbage.

Although Xiao Wen disdained the idea of using so many ingredients to make such a dish. However, he had to admit that the hot water cabbage was very delicious.

Currently, Xiao Wen's family had a mine. Even if they had ten cats, they would still be able to support him.

He also had the luxury of taking a look at how his sister-in-law had cooked this boiled cabbage.

Not everyone felt so comfortable while Xiao Wen was in the kitchen.

Less than a hundred miles away from the Cloud County, a group of disheveled and disheveled people were riding their horses and running wildly.

From the pig tail at the back of their heads, it could be seen that this group of people had fled after being defeated by Xiao Wen. However, on the grassland, Xiao Wen had betrayed them and captured them.

At this moment, the Manchu constables no longer had their original scale. After a few battles, their group of a few dozen people was already the rest of their group.

At this moment, one of the policemen looked behind him in panic, but found that other than the vast grassland, there was nothing else.

"Master Belle, we seem to have gotten rid of the Huns." He quickly urged one of the commanders near the group leader and said.

"Did you get rid of him?" Belle was overjoyed. He turned his head and saw that the Huns' pursuer had already disappeared.

With a sigh of relief, he ordered the troops to rest.
