Seeing that it was Gao Jin, the prince was angry at him for losing face, so he could only roll his eyes and stare at him, and said with a wry smile:

"Gao Jin, this is called coal, not coal, how many times have I told you, you just can't remember, besides, haven't you learned the ability of loneliness? I said it's okay, it's okay, that's okay, after it's built, let Jiang Wulang and them go in to test it, and before the results of the test come out, this prince won't go in first, it's okay! ”

Gao Jin nodded with satisfaction and said with a sneer: "In this way, the slave maid thinks it is the safest." ”

That's good.

Yuan Zhi snorted and ignored it, burying his head in reviewing the large pile of documents before the case.

The craftsmen are building a fireplace and a chimney passage of the fire kang in the Qinzheng Hall, the Zhengyang Hall, and the West Study according to the structural drawings drawn by the prince.

The prince works these days, and he handles affairs in the front hall of Shaoyang Palace.

After a while, Xu Xinchun came over to annoy the prince again, telling about the difficulties of promoting coal in the capital.

The old concept of hundreds of years really can't be reversed for a while.

"Lord Xu, the common people dare not use it, they think it is poisonous, because they don't understand the use value of coal, no one has used it like this before, if this prince takes the lead in using it, it is very safe, then it can play a role in promoting among the people, at least this winter, every winter in the future, everyone will not have to be frozen again."

Yuan Zhi put down the Zhu pen in his hand and said.

"It is a good thing that His Royal Highness has the world in mind and cares about the people, but this kind of unknown and unpredictable and dangerous thing is best not to be done by the East Palace himself in the future, there are all kinds of yamen below, thousands of people who eat imperial grain, and some things are handed over to the yamen to do."

I didn't expect Xu Xinchun to have this face, so he would nag and annoy.

"Okay, Prince Ben understands, Lord Xu, you should hurry up, you have to tell you, the entire renovation project of the East Palace is only allowed for ten days, you make it clear to the head of the Ministry of Industry and the internal chamberlain, there must be no mistakes."

Yuan Zhi gave a counter-advice in retaliation, which was equivalent to issuing an eviction order.

"Wechen understands that the prince's order has been issued, and those who can't carry it out will be engaged in military law, and Wechen will retire." Xu Xinchun bowed his hand and took his leave.

Witnessing Xu Xinchun leaving, Yuan Zhi was also full of feelings.

Since he was in charge of the country, he has been in a high position and has many sycophants, and there are very few people who are loyal and disobedient.

Although Gao Jin and Xu Xinchun are verbose, and sometimes you can't get off the stage, with these people by your side, you can often keep yourself sober.

In the past few days, inside and outside the imperial city and even in the capital, both officials and ordinary people know that the East Palace is doing some heating renovations, building fireplaces, etc.

The key is that the prince wants to use charcoal for heating, which is a change from the charcoal that has been passed down by his ancestors for hundreds of years.

and claimed to have found a solution to the toxic problem of carboniferous.

So far, the eyes of millions of officials, soldiers and civilians in the capital have focused on the East Palace.

On the fifth day of the first month of November, after this morning.

The East Palace seems to have entered the New Year state in advance, and the inner courtyard is generally not allowed to enter and exit ordinary people, and it is also crowded.

The fireplaces in the prince's west study, the Qinzheng Hall and the Shaoyang Hall were lit and burned, and the big kang was also burned.

After a while, a stinking and black smoke came from the special smoke exhaust ducts in the walls, rising from the rooftops into the sky.

The crowd watching outside the East Palace, except for the palace maids and eunuchs, were mostly members of the royal family, and everyone's faces couldn't help but change, and the soles of their feet retreated together.

The crown prince stood in the courtyard with his hands crossed on his waist, and the guards tried to persuade him to leave, but he smiled and stood still.

Ding Jiu, the general of the Qianniu Guard and the captain of the guard, Jiang Wulang, Sun Tiancang and other Qianniu guards tightly surrounded him and waited for him.

It seems that this thick black smoke is like a devil, and it will suddenly turn and attack the prince.

They looked nervous, but their positions did not move in the slightest.

This kind of posture, the prince is still satisfied.

In most cases, especially when going out, the personal guards must consciously surround the prince.

But there is one exception, that is, when the prince wants to meet others, he just can't stand in the way, and there can only be a few people on the left and right.

On the other side, Xu Xinchun, Gao Jin, Wei Changjin and other ministers also stood steadily, staring at the special chimney on the roof with blazing eyes.

After a stick of incense, the black smoke on the chimney gradually faded, which meant that the coal had entered a normal combustion state.

Yuan Zhi estimated that the fireplace and the large and small kang heads at this time were almost burned, so he said to everyone with a smile:

"Okay, now you can go in and have a look and experience the benefits."

As soon as the words fell, Jiang Wulang was already a tiger jumper, and rushed into the main hall of the west study first.

Several other Qianniu guards also entered the living room and bedroom of the west study.

Ding Jiuyi, the head of the guard, waved his hand, and more than a dozen Qianniu guards surrounded the prince and prevented him from moving his steps.

Over there, the Qianniuwei General Xie Bi, Zhonglang General Fan Hu and the others all turned around and took a look, nodded with a smile, and a satisfied smile appeared on their faces.

It's a very effective measure.

Sister-in-law Zhang, who rushed in Jiang Wulang's good friend, was biting her lip with her teeth and staring at the dynamics in the room with a nervous expression.

If after a while, people don't come out, and the people outside are ready to go in and save people.

Fortunately, after a while, the door of the west study opened first, and Jiang Goro appeared at the gate.

I saw that his face was full of red light, and he shouted: "Your Highness, it is so hot in the main hall of the study, there is no poisonous gas!" ”

Several other guards also came out of the house one after another.

They were all intact, and in unison, they said that the room was warm, and it was like two seasons away from the outside.

"Oh oh..."

Everyone flocked into the west study like children, and the results of the experience were all like what the prince had described before.

In this room, it's like spring, and outside is the cold winter when snowflakes are starting to fall, like two worlds.

"Well, nerds, let's be convinced." Yuan Zhi said aloud to the ministers.

"His Royal Highness the Crown Prince is a man of God, and we are ashamed of ourselves." Xu Xinchun and others gave up one after another.

"Several officials from the Privy Council and the Zhan Mansion are here, since this matter will soon spread after the coal flue gas is resolved, the next step is to comprehensively promote the entire palace city, the imperial city, and even the Jingshi."

"If there are not enough civilian personnel, that is, the army will be sent to assist, and the personnel and establishment of the army will be discussed and decided by the generals of the military hall, in short, the problem of heating should be solved in Beijing before the end of the year, so that the people can have a good and peaceful year."

"Jindi Coal Mine is about a thousand miles away from Beijing, and the transportation cost is very high, and the imperial court needs to look for it in the Qin-Shaanxi region, such as the mountainous area of Xianyang, and the Ministry of Industry has established a Mineral Resources Department, and the head Lei Jingtian is appointed as the chief supervisor, from the third rank."

"Yes."

The ministers surrendered their hands to the command.

Seeing the tired but happy demeanor of the ministers, Yuan Zhi was both happy and a little apologetic.
