The residue after the burning of plants is called wood ash.

Wood ash is an insoluble substance. Because wood ash is the ashes after the burning of plants, it is a mineral element contained in plants, and almost all the plants contain wood ash.

The main component of wood ash is potassium carbonate. When wood ash is applied in equal amounts, the fertilizer effect is better than chemical potassium fertilizer.

Therefore, it is an inorganic farm fertilizer with a wide range of sources, low cost, complete nutrients and obvious fertilizer efficiency.

Ying Zheng understood this principle, but the civil and military officials in the court were not clear about it. He just organized his words to the ministers who were circulating parchment paper and did not speak immediately.

It’s just that he is integrating the relevant things in his memory and then refining them to better make the Qin Empire better.

After all, the final operation of this matter requires the Qin officials to do it, so at this time, all the ministers must understand the principles and the benefits of the implementation of the fire kang.

Where benefits come, the action lies.

This is never out of date.

A quarter of an hour later, everyone present looked at it. Since they were not from Shanggongfang, they questioned the operability of the kang.

In their opinion, Ying Zheng was arrogant, so how could he understand such things?

Sometimes it is like this. It is impossible to judge people by their appearance and recognize people by their status. Such things are absolutely unsatisfactory. Judging people by their appearance is the shallowest.

"Your Majesty, is this kang feasible? Will my husband let him lose one or two tests?" In the end, Wang Wan told the question, after all, this was equivalent to questioning Ying Zheng, and the others lacked confidence.

"good!"

Ying Zheng did not make any excuses because this matter was simply unarguable. He was a noble emperor, so how could he be proficient in such a lifelike thing?

The talent is different, and it doesn't make sense at this time.

So, at this time, Ying Zheng did not say much, and nodded directly to Zhao Gao: "Transfer to the public to send a hatred to the court--!"

"promise."

Nodding and agreeing, Zhao Gao turned around and left. Compared with the other ministers in the study, Zhao Gao believed that the fire kang was feasible. This was not because he understood it, but because he believed in Ying Zheng.

This trust is special!

In Zhao Gao's view, Ying Zheng is the most dazzling god in this world and this era. The name Ying Zheng is almost walking with God for the people of the world and for all living beings.

...

Half an hour later, Gongshu Qiu walked into the study and bowed solemnly to Ying Zheng: "I, Gongshu Qiu, pay homage to Your Majesty, Your Majesty for thousands of years, and the Qin Dynasty for thousands of years!"

After taking a look at Gongshu Qiu, Ying Zheng nodded slightly: "You don't have to be too polite to be a good friend of Gongshu, just keep your body flat!"

"I thank Your Majesty!"

When Gongshuqiu stood up, Ying Zheng chuckled and said, "Husband, you are the best craftsman after Lu Ban. You can see if the kang is feasible."

At this time, Wang Wan handed the parchment that had been circulated to Gongshuqiu and said, "My husband, this is the drawing..."

"The kang is extremely important for this time and to resolve the snow disaster in the future. My husband loses and is troublesome!"

"Um."

Nodding, my husband took the parchment. At this moment, he didn't agree to anything. As a master, a master who always adheres to the spirit of craftsmanship, he knew in his heart that he could never easily draw conclusions without seeing anything he had seen with his own eyes.

After opening the drawings for about a quarter of an hour, Gong Shuqiu spoke and said, "From the parchment paper, the so-called tray kang is built with a wall of kang with bluestone. There is a flue in the wall of kang with flat bluestone. The stone slabs are covered with mud and flattened. After the mud is dried, it can be used.

"The kang has a stove mouth and a cigarette mouth. The stove mouth is used to burn firewood. When the smoke and hot air generated by burning firewood passes through the walls of the kang, it will generate heat, which will make the kang produce heat."

"In the end, the smoke is discharged from the smoke outlet of the kang through the chimney. On the drawings, the kang is built in the south of the room and accounts for nearly half of the room. It is surrounded by three walls, and the south is a large window."

"The structure "stove-flue-chimney" in the kang forms an effective thermal cycle that can store and achieve the heat in each part of the kang, and smoothly discharge without leaking smoke."

At this moment, Gongshu Qiu faced everyone's eyes and said, "Although I didn't see the real thing, based on my years of experience, it is feasible to have a kang."

"But the specific situation requires physical verification, but the effect will not be much worse!"

...

The words of Gongshu Qiu made all the civil and military officials in the study very happy. They knew in their hearts that if it was feasible, once the fire kang was launched, countless people would be alive.

As a minister of the Qin Dynasty, this is a great achievement.

"Um."

Nodding, Ying Zheng knew in his heart that Gongshu Qiu had basically expressed the characteristics of the fire kang, but it was still a bit incomplete.

After a thought came to mind, Ying Zheng decided to add: "The kang consists of three parts: a stove, a kang body and a chimney. The stove connected to the kang can cook, and the kang body can not only keep warm, but also sit and lie down."

"After the burning of straw, branches, etc., the temperature will be very stable, which is very suitable for the long winter north and northwest. In addition, the burning kang needs to be filled with half of the dry soil first, so it is easier to heat up."

"I call the ashes after the burning of straw, branches, etc., grass and wood ash. The ashes on the medical field can dispel cold and reduce swelling, eliminate symptoms and break accumulation. The main treatments are major stalkaria, carbuncle and ulcer meat, etc."

"The same wood ash mixed with dry soil, and after continuous burning, can be used as fertilizer to fertilize the soil, allowing the crops to grow more vigorously..."

...

Some problems are too profound.

Ying Zheng didn't want to mention it, but when he thought that such things would be common in the future, he blurted out everything he knew.

He was the emperor of the Qin Empire. Even if this was absurd, all the civil and military officials in the court could only accept it.

After this incident, Ying Zheng saw the possibility of igniting the technology tree. After all, he is the emperor. Some things only require one sentence and no explanation.

Zi said no wonder that the strange powers and the gods are in chaos!

If an ordinary person had any wonderful ideas, under such a situation as the Great Qin Empire, he would most likely be imprisoned, sent to the Mausoleum of Mount Li, and be questioned.

However, under the absolute imperial power, everything breeds the best times, especially the emperor who controls all this, not others.

When he thought of this, Ying Zheng was overjoyed. After this incident, he saw a shortcut, a shortcut that made the Qin Dynasty boundless forever.

...

The thoughts flashed through his mind, and were almost suppressed by Ying Zheng one by one in an instant. He knew in his heart that the most important thing at the moment was to deal with the snow disaster.

As for the others, there is time.

As soon as he thought of this, Ying Zheng looked at Gongshuqiu: "Honey, how long will it take to build a kang between you?"
Chapter completed!
