Since Li Xiu moved to his new home, the original old house has no longer lived in. The doors are usually locked. Although the flowers, plants and trees in the yard are unattended, they have grown more lushly. The yard is gradually covered with weeds. Standing in the half-person-high courtyard wall, it looks like a haunted house.

However, Li Xiu brought the key to the old house today. Not only did he come, but Ma and Princess Pingyang also came together. After he opened the door, the servants of the princess's mansion immediately cleaned the yard briefly, and then a big cart was pulled in, and a large cart of crushed coal was pulled on the car, which was also what Li Xiu specifically asked for.

"What should I do next?" Mr. Ma came over and threw an iron guy at Li Xiudao. He saw that the iron guy was in a strange shape. There was a cylinder below, a long pole connected to it, and a "t"-shaped handle on the top. I don't know what it is for?

"It's very simple. If you add loess to gravel charcoal, you can take up one part of loess and three to four parts of carbohydrate, and then add water to make it into mud!" Li Xiu said with a smile. What he was going to make was honeycomb coal. I remember that when he was a child, few people would buy finished honeycomb coal. Generally, they would buy some cheap crushed coal to make themselves. The tool he used was the hand-pressed honeycomb coal machine in his hand. He could only make one honeycomb coal at a time. The efficiency was definitely not comparable to that of the machine. But after being proficient, he could produce all the honeycomb coal used for a winter in one day.

The coal slime was quickly adjusted. Li Xiu walked over with a honeycomb coal maker and smashed it hard, causing the coal slime to enter the mold below. Then he found an open space in the yard and pressed the handle above to remove the honeycomb coal. As a result, a cylindrical honeycomb coal with seven holes on it appeared on the ground. Originally, Li Xiu wanted to make a twelve hole, but the craftsman said it was difficult to make it, so he could only make such a seven hole first.

Next, Li Xiu relived the joy of childhood, but at that time he could only watch from the side, but now he could make honeycomb coal with his own hands. However, he soon found that this job was not easy, especially in this hot weather. After a while, his whole body was soaked with sweat, his arms were sore and sore, so soft that it was a little unrestrained.

"Li Ji, take a break, don't get hot!" Princess Pingyang felt a little heartbroken when she saw Li Xiu sweating profusely, and shouted immediately.

Li Xiu was indeed hot and tired, so he took the opportunity to put down the honeycomb coal machine in his hand, and immediately replaced the servants of the royal palace. However, at this time, Ma Ye said with some doubt: "Boy, is it useless to beat these eye-catching carbohydrate cakes?"

"Of course it is useful. Carbonite is a good fuel. You know this without me telling you. As for the shortcomings of the carbonite you mentioned, the honeycomb coal in front of you can solve all the problems." Li Xiu explained with a smile.

"Really or false?" Mr. Ma still said in disbelief when he heard this.

"Of course it's true. The temperature is so high now that these honeycomb coals are almost ready to be used this afternoon. Let's go back and build a stove and wait!" Li Xiu said confidently. He has used honeycomb coal since he was a child, so he still has this confidence.

Seeing Li Xiu so confident, Ma Ye couldn't help but believe it a little. He followed Li Xiu back to his new home, with a craftsman with him. Then, under the guidance of Li Xiu, he built a honeycomb coal stove in his kitchen. Because it was impossible for people to live in the kitchen, and windows were often ventilated, so there was no need to use exhaust pipes. Anyway, there was no such thing as Li Xiu's hometown in his previous life. Only when the stove was erected in the bedroom in winter would he add an exhaust pipe.

After the stove is built, it is best to dry it in the shade so as to prevent the inside of the stove from bursting. However, in order to show the effect to Ma and others, they don’t care about so much. Now people put the straw in the ignition, and added a few pieces of charcoal. At least the inner wall of the stove must be dried, otherwise the honeycomb coal will not be easily ignited.

When it was late in the afternoon, although the honeycomb coal exposed to the sun was still a little wet, it was already available. Li Xiu ignited the furnace again, and the charcoal was burned red, so he put the honeycomb coal in. The temperature of the charcoal was very high when it burned, and Li Xiu kept fanning the air inlet. In a short while, the first honeycomb coal was already ignited, and the light blue flames rose high. It seemed that the coal was of good texture.

"This...this is enough?" Mr. Ma asked again in confusion as he looked at the burning honeycomb coal in the stove.

"Of course, this kind of stove can usually add four pieces of honeycomb coal. Generally, one piece of honeycomb coal can be used to make a meal, or even boil a pot of water and add another piece. Just plug the air inlet, and this honeycomb coal will burn very slowly. When used, the fire inside will generally not be extinguished. Isn't it very convenient?"

Li Xiu briefly introduced the use of honeycomb coal. In later cities, basically no one uses honeycomb coal, and even the countryside uses gas. Thanks to his childhood, he lived in the countryside, otherwise he really didn't know how to use honeycomb coal.

After listening to Li Xiu's introduction, Ma Ye was still a little confused, so it was not his fault, because he basically didn't go into the kitchen and didn't know how troublesome it was to cook and burn the fire.

However, Princess Pingyang was a little excited when she heard this: "So that's it. According to what Li Jijiu said, after using this honeycomb coal, it will not only make the fire easy, but the kitchen will also become very clean. You don't even have to worry about not being able to find dry firewood on rainy days!"

"Wait, this carbonite is so black, where is it clean?" Mr. Ma asked again in confusion.

"Uncle Ma, you don't know that the firewood burned when cooking in the kitchen often has ash flying. In order to attract fire, some straw should be placed in the kitchen, which can easily breed bugs or mice. However, the honeycomb coal is much cleaner. You can make a meal just one piece, without adding firewood in the middle, and you don't have to worry about the size of the fire. It's so convenient!" Princess Pingyang explained again. Although she is a princess, cooking skills are one of the compulsory courses for women in this era, so she is not unfamiliar with the kitchen.

Not only Princess Pingyang said this, Yuechan and several maids also praised the honeycomb coal stove. Liu'er even suggested cooking on the stove today, which was also approved by Li Xiu. So he added a piece of honeycomb coal to it and asked Yuechan to cook a few special dishes. After all, it was time for supper.

The food was ready in a short while. This time, Princess Pingyang did not leave. The three of them sat there and chatted. At this time, Ma finally dispelled his suspicion and said, "Since you all say that this honeycomb coal is very good, it must be true. Moreover, the carboniferous mine is open-pit, so you only need to hire someone to excavate. The transportation can also be transported through water. The cost is very low. In this way, this honeycomb coal seems to be really profitable!"

The more Ma Ye settled the accounts, the brighter his eyes became. Before, he thought that this honeycomb coal was just a fuel like charcoal, and the profit was probably limited. However, except for labor and transportation costs, there was no big cost. Moreover, the profit of a piece of honeycomb coal was indeed very small. However, if there were so many families in Chang'an City, if each of them used honeycomb coal, the profit would be very terrifying.

"Hehe, it's not all. When it's winter, every household needs to keep warm. In the past, charcoal was usually used, but the price of charcoal was too high, and most people really couldn't afford it. However, our honeycomb coal was much cheaper, and I could also design a new stove without worrying about being poisoned during burning. In this way, I can definitely grab the sales of charcoal in winter!" Li Xiu smiled again.

"It's great. Finally, there is a way to make money. In the past few days, I have asked people to increase the output of carbonite. In addition, Chang'an also recruits people and build a honeycomb coal workshop. When you save enough honeycomb coal, you will start selling immediately, and strive to use our honeycomb coal in the entire Chang'an City!" Mr. Ma said enthusiastically at this time. With money, he can continue to buy land and houses.

Seeing Mr. Ma's excited look, Li Xiu stopped him with a smile and said, "Uncle Ma, don't rush to sell honeycomb coal. You have seen it just now. The production process of honeycomb coal is not complicated. As long as the honeycomb coal appears on the market, I am sure that in a few days, someone will find out how to make it. At that time, the money we get will be distributed to others."

"What are you afraid of? The carboniferous ore is in our hands. How can they make honeycomb coal without carbon?" Mr. Ma said without any worries.

"But Uncle Ma, can you guarantee that there is no carbonite ore in other places?" Li Xiu suddenly blinked at this time. Since he wanted to make money, let Mr. Ma make enough, so that he would not bother him with making money in the future.

"What you mean is to block the news first, and then send someone to buy all the carbonite mines that can be found!" Master Ma's eyes lit up when he heard this. He was too excited just now, otherwise he would have thought of this with his wisdom.

"That's right, if Ma Ye only wants to do the honeycomb coal business in Chang'an, then buy all the carbonite mines near Chang'an. If you want to make it bigger, you can go to a farther place to buy more carbonite mines. I can tell you that carbonite will definitely be in the market. Holding enough carbonite mines in your hands is equivalent to having a real gold mountain!" Li Xiu bewitched slightly.

At this time, Li Xiu suddenly thought that if he married Princess Pingyang in the future, wouldn’t the carboniferous mines Ma Ye bought now belong to his children and grandchildren? So this is also considered for his descendants. Thinking of this, he couldn’t help but look at Princess Pingyang next to him, and sometimes he really wanted to marry her home early.
