Daqin: Check in at the beginning of 18 and ask Zulong to abdicate

"Since the heating effect of the kang I designed is not bad, I plan to ask the masons to build more."

Ying Zigao hurriedly said, "First build a kang for every rest room of your Ouchi guards!"

"Thank you, Your Majesty!" Hearing these words, the chief guard couldn't help but feel hot, and hurriedly agreed loudly.

After dismissing the chief guard, Ying Zigao said to the accompanying eunuch, "I have decided to build a kang for the eunuchs and maids' resting rooms!"

"Thank you, Your Majesty!" The accompanying eunuch hurriedly agreed with excitement!
"By the way, ask the masons to recalculate the cost and man-hours required to build the kang, and report it to me!"

Ying Zigao then said seriously: "The cost of heating the kang overnight is also calculated from this!"

"Your servant understands!" The accompanying eunuch hurriedly agreed.

Before you know it, it's dusk.

Ying Zigao had just finished eating the egg stewed noodles from the imperial kitchen when the craftsman in charge rushed to see him.

"Your Majesty, I have come to announce the good news to Your Majesty!"

When the craftsman in charge saw Ying Zigao, after paying homage, he said seriously.

Ying Zigao asked with great interest, "What's the happy event?"

The craftsman in charge hurriedly said: "Your Majesty, I have manufactured a heating system with all cast iron components according to your Majesty's instructions!"

"All done?" Ying Zi regained his energy immediately, and asked hastily, "Where are these components placed?"

"It's stored in the warehouse of the imperial garden!" The craftsman in charge said hurriedly: "The heating system in the solar greenhouse has also been replaced with cast iron components. After testing, the effect is much stronger than the original ceramic components!"

Ying Zigao hurriedly said, "I want to take a good look!"

As he spoke, Ying Zigao strode to the imperial garden.

Walking into the solar greenhouse, Ying Zigao felt a gust of warm wind blowing towards his face!
When I looked up, I found that all the heating pipes and radiators in the solar greenhouse were made of cast iron!
"Good job!" Ying Zi said.When he strode to the heating pipe, he couldn't help reaching out and touching it.

"Your Majesty, be careful!" The craftsman in charge and the accompanying eunuch hurriedly said loudly!
Of course Ying Zigao would not touch the heating pipe directly with his hands.

Putting his hand aside and feeling the heat of the heater, Ying Zigao said loudly, "Well done! The effect is indeed much better than Tao Guan!"

"Thank you, Your Majesty!" the eunuch in charge said hurriedly.

"Since the cast iron heating parts have been successfully produced, they have also been tested."

Ying Zigao nodded in satisfaction, and continued, "Hurry up and install heating in my imperial study and bedroom!"

"The minister obeys the order!"

The craftsman in charge quickly agreed.

In the early morning of the next day, Ying Zigao called the chief guard to the main hall.

Seeing that the chief guard came to the main hall, the ministers couldn't help being surprised.

Although the chief guard has a high official position and high status, he will not go to the hall except for special periods.

"Could it be that the emperor is going to make another big move?"

Looking at the chief guard, the ministers couldn't help but feel worried!

"My dear friends, you must be curious why I let the head of the guard go to court today."

Seeing the surprised faces of the ministers, Ying Zigao said seriously: "I asked the chief guard to come and tell everyone about the heating effect of the kang!"

"Your Majesty, what is this kang?" the left servant of the Ministry of Industry asked hurriedly.

"This kang is a heating device newly designed by me!"

Ying Zigao hurriedly said: "After the design, I have asked the craftsmen to build a kang in the rest room of the Ouchi guards, and use them to keep warm when the Ouchi guards are resting!"

Hearing this, the ministers couldn't help being shocked!
They really didn't expect that Ying Zigao invented a new heating device!
The Zuo servant of the Ministry of Industry was even more energetic, and asked earnestly: "Your Majesty, I dare you, what is the heating effect of this kang?"

Ying Zigao hurriedly said: "I called the head of the guard this time to tell everyone about the heating effect of the kang."

While talking, Ying Zigao said to the chief guard: "Talk to all the ministers about the kang!"

"My minister obeys the order." The chief guard hurriedly agreed, and then said seriously: "The heated kang invented by your majesty has a very good heating effect! Just put firewood and coal bricks into the door of the kang, and after lighting it, you will soon be able to let the heat out." The kang is getting hot!"

"After lying on it, the whole body is warm, and you don't feel cold at all when you sleep!"

The chief guard went on to say: "The young guards in Ouchi usually have trouble sleeping in winter, and wake up from freezing before dawn. Now that there is this heated kang, each sleeps heavier than the other. When they should be on duty in the morning, they have to sleep again. I, the head of the guard, shouted one by one!"

Hearing this, the ministers couldn't help laughing one by one.

The left servant of the Ministry of Industry hurriedly asked seriously: "Your Majesty's kang is so effective for heating, what is the structure? How was it built?"

"This heated kang is to build the wall of the kang with mud bricks, leave a hole and cover it with mud slabs or thin stone slabs. The stone slabs are covered with mud and smoothed, and then the kang mats are spread."

Ying Zigao hurriedly said patiently: "This job is very simple, and the requirements are not high. An ordinary bricklayer in the countryside can do it well!"

The left servant of the Ministry of Industry nodded.Then he asked seriously: "Your Majesty, what is the cost of this kang?"

Ying Zigao hurriedly said: "The cost of the heated kang is mainly the labor and masonry materials of the masons.

It takes at most one day to build a kang, and the building materials needed are also the most common folk mud bricks and clay!The cost added up is no more than fifteen yuan! "

"The cost is only fifteen cents!" Hearing this, the ministers couldn't help being shocked!
The cost of a briquette stove is [-] Wen, which is already very low.

Unexpectedly, the cost of this heated kang is lower than that of a briquette stove!
"Your Majesty, the cost of this kang is very low."

The left servant of the Ministry of Industry was slightly taken aback, and then asked: "What about the cost of fuel?"

"The fuel can be ordinary firewood, straw, or briquettes made of coal powder and loess!"

Ying Zigao continued, "The cost of fuel is even lower!"

The left servant of the Ministry of Industry, Qiao Zhener, showed his true character again, and asked hurriedly, "Your Majesty, is the cost of coal bricks lower than that of briquettes?"

Unexpectedly, the left servant of the Ministry of Industry kept asking the emperor, and the Minister of the Ministry of Industry couldn't help but secretly became anxious.

This subordinate who was busy thinking about himself kept winking.

The left servant of the Ministry of Industry turned a blind eye, and still looked at Ying Zigao with a straight face!
"The briquette is made by mixing one part of plum powder and three parts of loess evenly to make coal blocks and then dry them in the sun!"

Ying Zigao said patiently.
