Hearing Hu Bao's question, the uncle laughed and said:

"You see there is a vent under the coal stove. If you remove the cover of the vent when cooking, the fire in the coal stove will increase. After cooking and then block the vent in the coal stove, the coal fire will become smaller."

If we cook two meals, we need four briquettes a day and a night. If we only cook one meal and have some roasted sweet potatoes left to eat, three briquettes a day are enough.

A piece of briquettes costs two cents, and three briquettes a day cost six cents. It is much more cost-effective than burning coal. As for charcoal, there is no way to compare. Ordinary people cannot afford charcoal at all..."

When talking about the price of briquettes, the uncle immediately showed a happy smile on his face.

How important briquettes are to the people in winter, only the people themselves know best.

In the past, when coal was burned, the whole room was filled with black smoke and a choking smell, which could lead to death from poisoning.

Nowadays, there is almost no black smoke when using briquettes, and the smell is also very small.

Regarding the issue of briquettes, not only did the uncle not understand clearly, Hu Baoyueyang, Li Ruolian and the other three did not understand it even more.

Of course, only the time traveler Zhu Cixiang knew what was going on.

Briquettes are actually briquettes from later generations. Before being made into briquettes, the coal has been washed with coal washing technology to remove toxins.

Ancient rooms could not be completely sealed, so there was no danger in using briquettes.

The briquette fire is not as big as the previous coal stoves, but there is no problem in boiling water for cooking.

The most important thing is to save coal. In the past, cooking a meal required four or five kilograms of coal, but now it takes fifteen or six kilograms a day.

If you use this kind of briquettes, you only need three briquettes a day.

In the era without briquettes, cooking was very coal-intensive. An average family of five would use at least fifteen or six kilograms of coal a day, and those with a larger population would use thirty or forty kilograms.

Based on the selling price of two kilograms of coal for one penny, a household would spend eight to twenty penny on burning coal a day.

One month is 240 to 600 taels of silver, and a year is 20 to 56 taels of silver.

For wealthy families, this is just a small amount of money.

But for ordinary people, spending a lot of money on fuel is a big deal.

Because for an ordinary family, the annual income is only more than ten taels of silver.

But you can't do it without spending this money. This is the capital of the Ming Dynasty, not an ordinary mountainous countryside. You can just find firewood in the fields to burn.

Without fuel, there is no way to cook. The most important thing is that it can raise the room temperature in the cold winter.

Just look at the quilts and cotton-padded clothes in the uncle’s home and you will know the importance of having a coal stove in the room.

If you use briquettes instead, you only need three briquettes for cooking in a day.

Even if each briquette sells for two cents, it only costs six cents a day, which is a savings of one to two cents compared with the original price.

After a month, I have fifty or sixty cents left, and after a year, I have more than half a tael of silver.

Half a tael of silver is definitely a lot of money for ordinary people.

Moreover, honeycomb briquettes have another advantage, that is, the coal stove will not go out if it is sealed when not in use, and there is no need to bother with re-lighting the fire every day.

Royal Group's briquettes not only brought benefits to the people of Ming Dynasty, but also made some money for themselves.

Of course, even if the profit is very thin, if it can't cope with the huge demand, it won't be a problem to make millions of taels of silver a year!

After leaving the uncle's house, Zhu Cihong visited more than a dozen houses, two of which were considered big ones.

Zhu Cixi found that except for one large household that used charcoal for heating, the rest of the households basically had coal stoves and briquettes, and most of them had sweet potatoes on the coal fire.

With so many households in the capital, Zhu Cixiang didn't know how much briquettes would be used in a year, but he knew that this was a huge income for the Royal Group.

There is no cost for coal, as long as you pay for the work. Briquettes are not all coal. One hundred pounds of coal contains at least twenty pounds of loess, which directly reduces the price of coal a lot.

While bringing warmth to the people of the Ming Dynasty, it also allowed the Royal Group to make some profits. The timely release of honeycomb briquettes on the market made Zhu Cixiang value Shen Wanwan and Li Yun's abilities even more!

"hehe……"

Zhu Cixiang stood beside the ski car and couldn't help but giggle:

"Shen Wanwan, I really saw you right. It seems that Li Yun must have become a talent, hehehe..."

Seeing Emperor Shenwu's silly smile, Hu Bao quickly cupped his hands and said:

"Your Majesty, where will you go next?"

Zhu Cixiang pointed to the dozen quilts and down jackets in the car and said:

"Sent two quilts and two cotton-padded clothes to the uncle's family, and the remaining quilts and cotton-padded clothes are distributed to a few people in need!"

"OK!"

The three of them agreed and immediately picked up their quilts and down jackets and took action...

Zhu Cixiang took the three of them for a long tour of the capital. The entire capital was silent, and only the whistling of the cold wind could be heard.

When Zhu Cihong parked the ski car in front of the gate of the Military War Bureau, the four of them heard the sound of iron banging.

"Your Majesty, the War Bureau has not stopped work?"

Zhu Cixi nodded:

"With such cold weather, water power can no longer be used. The craftsmen must be working purely manually. It's really hard for them. Go in and take a look!"

As soon as the three people jumped off the ski car, the guards on duty immediately reacted from their confusion. They immediately rushed out with rifle guns and blocked the way of the three people!

"Stop, anyone who takes another step forward will be killed on the spot!"

Hu Bao was furious and immediately shouted:

"Be brave, His Majesty Shenwu is here, open the door quickly!"

The leader, General Li Fang, was stunned when he heard this. He looked at the three people dressed in weird clothes and suddenly snorted:

"Take it!"

After the commander-in-chief gave the order, the guards of the Military War Bureau immediately stepped forward to surround Hu Bao, Li Ruolian and Yue Yang, approaching them with rows of shining bayonets.

Feeling the murderous intention of the guard, Hu Bao was shocked and hurriedly took out the Qianqing Palace badge:

"Be brave, open your eyes and see clearly, this is the palace badge of Qianqing Palace, and our family is the eunuch in the hand of Emperor Shenwu!"

Yue Yang and Li Ruolian also immediately showed their Jinyiwei waist cards:

"We are the commander of the Jinyiwei, Li Ruolian, and the commander of the Jinyiwei, Tongzhi Yue Yang. Don't get me wrong, put away your weapons quickly."

The boss looked at the three of them coldly, not looking at their badges at all, but the guards would not attack until he gave the order.

"Where is the imperial decree? We only recognize His Majesty Shenwu's imperial decree!"

Hu Bao, Li Ruolian and Yue Yang looked at each other with anger in their eyes. It was unreasonable for them to follow Emperor Shenwu and not be able to enter the war situation!

If it weren't for the military battle, Li Ruolian, Hu Baoyueyang and the others might have used force directly. Knowing their status in the Ming Dynasty, no one except Emperor Shenwu would dare to ignore them!

Zhu Cixiang just looked at them with a smile. He was not angry at all at the guard's rudeness.

For a top-secret department like the Ming Dynasty War Bureau, the stricter the interrogation, the better, and spies and unrelated personnel must not be allowed to sneak in.

The three of them could not deal with Li Fang. He smiled slightly, then took off his down jacket and waved his hand to the boss:

"Li Fang, open the door!"

Hearing a familiar voice coming from the monster, Li Fang hurriedly looked up and saw Emperor Shenwu showing his true face in Lushan. He was shocked and hurriedly stepped forward and bowed to salute:

"I didn't know that the Holy Spirit was coming, and Li Fangxin deserved to die..."

Seeing the general coming forward to salute, the guards of the Bingzhan Bureau also changed their appearance. They immediately put away their rifles and knelt down on one leg:

"Viva viva!"

Zhu Cixiang smiled faintly:

"Well done, officers and men. It is your duty to guard the military situation. How can I blame you? You can all be spared!"

Li Fang hurriedly led his men to thank him:

"Thank you, Your Majesty, long live my emperor!"

At this time, Hu Bao, Li Ruolian, and Yue Yang realized that it was the four of them's weird costumes and stylish ski cars that caused the misunderstanding among the guards at the Bingzhan Bureau.

They immediately took off their down jackets and exposed their heads. Only then did Mr. Li Fang realize that they were really two senior officials from Jinyiwei and the emperor's personal eunuch.

He hurriedly hugged the three of them:

"excuse me!"

Even though they know the identities of the three people, they still won't let them go without an imperial edict, but the situation is different now. Shenwu is at the scene, who dares to stop them!

General Manager Li Fang hurriedly led people to open the gate himself. Zhu Cixiang flicked his wrist and increased the accelerator of the snowmobile, and the snowmobile roared into the courtyard of the Military War Bureau.

Before Li Fang and others understood what was going on, suddenly a red shadow flashed in front of their eyes. They were frightened and took two steps back. They looked at their Shenwu Emperor in horror...

The earth-shattering shouts outside had alarmed the scientists inside. Bi Maokang and Song Yingxing hurriedly brought Zhao Yuanhua, the three Sun brothers and more than a dozen people out to watch.

They had just come down from the science building when they suddenly heard a strange sound, then saw a red light flash and a red monster parked on the snow in the courtyard.

Everyone was shocked and almost shouted in unison:

"Ah, what is that?"
To be continued...
