Inside the Temple of Manna.

An attendant came over to ask Qin Huaidao for advice, saying that the carriage had been pulled in, and there were many things in the carriage, so he didn't dare to move it easily for fear of breaking it, so Qin Huaidao retreated and followed outside.

There were a total of five stoves in the car, but there were a lot of honeycomb briquettes, Qin Huaidao took away the bag of gypsum, picked up a stove, motioned for everyone to move the others, and entered the Manna Hall together.

Everyone gathered around curiously, looking at this simple thing in Qin Huaidao's arms and being a little suspicious, so ugly, can it work? Even Li Er looked at Fang Xuanling with a little doubt in his eyes.

Fang Xuanling didn't know if it could be done, so he motioned to Li Er to be calm and not impatient, anyway, everything was brought, try it and it would be clear, and said bluntly: "Virtuous nephew, show it to everyone and see how to use it." ”

Qin Huaidao agreed, and just as he was about to start, he saw Li Tai, the king of Wei, and Li Chengqian, the crown prince, coming over, the two of them bowed down to Li Er first, and also looked at the stove curiously, Li Tai, the king of Wei, said bluntly: "Father, this thing looks a little simple, if it is given to the people in the name of Zhenguan, I am afraid it will damage the royal face." ”

"That's right, this thing is too ugly, Lord Qin, can't it be made more exquisitely? After all, it will be given away in the name of the imperial court in the future, and it will be crowned with the word 'Zhenguan', which is really inappropriate. Li Chengqian also said.

When you come up, you question, is this to find fault? Qin Huaidao was not happy, and was about to open his mouth to refute, Fang Xuanling hurriedly said: "The appearance of the problem will be discussed later, and the Ministry of Engineering can study it later, and it will look good, the key is whether it can be used, virtuous nephew, try it first." ”

"Yes, try it first, and the old man will find someone to study and study the appearance problem." Duan Lun, the secretary of the Ministry of Industry, agreed.

However, Qin Huaidao's temper came up, and he said coldly: "His Royal Highness the Crown Prince and King Wei are right, it is indeed ugly, so forget it, so as not to damage the royal majesty and the image of the court." ”

When he said this, the audience was stunned, they didn't expect Qin Huaidao's temper to be so rigid, isn't it just a question?

It's just that in this way, the crown prince and King Wei can't get off the stage.

Fang Xuanling still wanted to play a round game, but Qin Huaidao hurriedly said: "The prince and the king of Wei questioned the reasonableness of the things made by Weichen, and Weichen was convinced, there must be a better way to replace it, let the prince or the king of Wei be responsible for this heating thing, Shengshang, Weichen will retire." ”

The ministers looked at each other, this is to be tough to the end, and they all looked at Li Er.

Li Er's face was also a little ugly, reprimanding Qin Huaidao, there is a suspicion of defending the prince and the king of Wei, reprimanding the prince and the king of Wei, Qin Huaidao's words are indeed a bit of a fuss, and even a suspicion of committing a crime.

Qin Huaidao of the Wei Dynasty bowed and said solemnly: "Lord Qin, this king is not questioning your merits, but just talking about the matter, please bear with me." ”

After speaking, Li Er of the Wei Dynasty made a gesture and continued: "Father, since this furnace is named 'Zhenguan', it can't be too casual, the appearance is more exquisite, and it can better reflect the father's care and benevolence for the people, and I implore my father to order that the sons are willing to be responsible for making this furnace." ”

The crown prince Li Chengqian also stepped forward and said: "Father, I am the crown prince, I should set an example, what to do for the people, it is better to leave it to me to do, if you don't do it well, you are willing to be punished." ”

Qin Huaidao saw that this was to grab the credit, pick peaches, and leave in no hurry, he was a little funny in his heart, the stove was given to the people for free, whoever is responsible for doing it, who can harvest the hearts of the people, this Li Er is not dead, the king of Wei and the prince jumped out to snatch the hearts of the people, this is looking for death.

Li Er looked at the crown prince and the king of Wei, his face was a little gloomy, no one knew what he was thinking, and immediately looked at Qin Huai and said, "Huaidao, how about you demonstrate." ”

"Wechen obeys." Qin Huaidao had a premonition that a good show was going to be staged, so he didn't leave, came to the brazier, picked up the tongs and put some charcoal in the stove, and then put a honeycomb coal in it, the charcoal was burning vigorously, and it was easy to ignite the honeycomb coal.

Everyone saw that the honeycomb coal was burning, and there was no poisonous smoke, and the smell was not big, so they all gathered around curiously to watch, Li Er saw a hole below, and asked, "What's the use of the hole below?" ”

"Shengshang, the opening is to facilitate the air flow to enter, to help burn, if you don't use it, you can use a rag cloth or the like to plug it, the fire will burn slowly, but it will not be extinguished, unless it is completely burned through, or the small hole next to it is blocked, and it will be extinguished if there is no gas to enter." Qin Huaidao explained.

When Li Er heard this, he shouted to the waiter: "Quick, that rotten cloth come and try it." ”

Soon, a piece of rotten cloth was sent over, Qin Huaidao took it and kneaded it into a ball, directly blocking the hole below, everyone saw that the small flame that burned suddenly disappeared, and the temperature was reduced a lot, but it was not extinguished, Qin Huaidao opened the rotten cloth, and the flames came out again, and the temperature went up.

"How amazing is that?" Duan Lun, the secretary of the Ministry of Industry, sighed.

Qin Huaidao sandwiched two more honeycomb coals and put them in, just filled them, and explained: "Holy Lord, ministers, it is best to put three at a time, and when the top one is almost burned, you can take out the bottom one and throw it away, put the remaining two back, and fill in another one, and so on repeatedly, to ensure that the fire is not extinguished, and it can be saved, when it is not used at night, it is blocked with a rotten cloth, leaving only the small hole next to it, and the fire will not be extinguished the next morning, so there is no need to light the fire again." ”

"Can you wait until the next day?" Li Er asked in shock.

Qin Huaidao explained: "Of course you can, open it when you do it, seal it when you don't do it, if you boil water, or keep it warm, you can seal it half, just leave a little hole, you don't have to look at it all the time like burning wood, you can free up time to do something else, it's very convenient." ”

Everyone looked incredible and praised it.

Fang Xuanling couldn't help but praise: "This stove seems simple, but it is quite magical, this honeycomb coal is even more peculiar, and it is convenient to burn it if it is left empty in the middle, right?" Virtuous nephews. ”

"I've never seen this thing, it's quite magical, could it be from your "Secret Archive of Things"?" Duan Lun, the secretary of the Ministry of Industry, looked at his feelings curiously and asked.

"Exactly!" Qin Huaidao responded indifferently, and it was just right to have a source, so as not to be suspicious.

"This temperature does not have to be low at all, and the fire is concentrated, and it looks very slow to burn, I heard Fang Aiqing say that it is more cost-effective than charcoal for heating, Huaidao, how about the output?" Li Er is worthy of being the first emperor of the ages, and he looks at the problem and points to the essence.

Qin Huaidao said with reservations: "At present, the output is about 10,000 per day. ”

"Too little, far from enough, my people are thousands, in this way, you do your best to produce, the production of the stove." Li Er looked at the King of Wei and the crown prince as he spoke, and was a little difficult to make a decision for a while.

King Wei hurriedly said: "Father, give it to your sons, and promise to do a good job." ”

"Father, it's better to leave it to your sons, and never let your father down." Li Chengqian also hurriedly said.

Who to hand over to is a matter of national capital, and the ministers are silent.
