"Grandpa Xiao, what are your instructions for summoning the little one?" Seeing that Zhang Dafu had won the favor of Xiao's father-in-law, Liu Fuhai couldn't help but be a little anxious.

"Well, do you know the casting process?" Xiao Chen asked.

"I understand, the small one is a craftsman, and he can deal with gold, silver, copper and iron, I don't know what my father-in-law wants to build?"

What Xiao Chen wants to build is a boiler.

He plans to install a modern heating system in the store.

In fact, the palace also has its own heating system, which is the so-called 'fire heating', which is to lay many underground fire tunnels under the palace, and then dig a pit about two meters deep outside the palace as a stove to burn charcoal.

The hot air is conducted to the ground in the palace through the underground fire channel, which not only has a large heat dissipation area, but also has a very uniform heat dissipation area, and there is no soot and dust pollution, which is basically the same as our current floor heating system.

But only the emperor, the queen mother, the queen mother and the concubines have this kind of treatment, and no one else in the palace can enjoy it.

Xiao Chen didn't.

If the test can be successful, then I will definitely install a set in my house when I go back......

This is also his first invention in ancient times as a modern person.

The advanced concept directly stunned the expert Liu Fuhai.

"Oops! No wonder the big guys say that Gonggong Xiao is a Wenqu star, such a subtle thing is not something that mortals can imagine! “

In fact, the heating system is not very complicated, and the construction principle is quite simple.

First you have to cast a large boiler to hold water, then connect it to the various rooms with metal pipes, and then install radiators to dissipate heat.

After the boiler water is boiled, it will automatically circulate until all the pipe radiators are all hot water, and the heating effect will be achieved.

The boiler room can be built outside the yard, so there is no safety hazard of causing a fire.

The royal superintendent had skilled craftsmen, and there were no problems in building boilers and tubes, but there were two problems that could not be solved.

The first is that with the current sand turning process, the heating radiator with a more complex structure cannot be manufactured, and even if it is barely made, it may not be usable.

The second question is how to connect the pipes? Nowadays, there is no electric welding technology, but soldering is available, but it is not reliable, as long as the water pressure is high, it is easy to leak.

"The radiator is not done, as long as the pipe is made thicker and bent into a snake shape, it will have the same effect." Xiao Chen solved the first problem in one sentence.

"As for the method of connecting the pipes, it is also very easy, as long as the clay, lime, fine sand, egg white, and glutinous rice soup are pasted in the connection according to a certain proportion, and then wrap a few more layers of water-soaked gauze ......"

"Oops! Don't say it, Gonggong Xiao's method is only afraid that it can really work! Grandpa Xiao, say that you are not a god descending to earth, no one will believe it! Liu Fuhai had a very smart mind, and he was overjoyed immediately after a little silence, so much so that he didn't choose what to say.

"Well, whether it works or not, let's try it first." Of course, Xiao Chen would not tell him that his grandfather in his previous life was a retired worker in the boiler factory......

After a long time in the storage hall, I couldn't stand the cold, so I found an excuse to leave.

I was holding my breath and laughing again, sir, I was obviously promoted to a Bingbi eunuch, a dignified three-class, but I didn't expect to become an archivist!

Where to reason?

I can only find the queen.

"That's the way it is!" When I arrived at Kunning Palace, I told Murong Yueqiu about today's experience, and the more I talked, the more angry I became, and I felt like a wretch!

"Look at the way you are angry, what? Can't stand this little grievance? Unexpectedly, the queen not only didn't get angry, but also looked at Xiao Chen with a smile.

Is there a mistake with this lady? I'm your man!

I was so miserable outside, but it was your face that I lost?

Let's just say that the damn Gong Shouli didn't even look at his mother......

"I remember that the ancient sages once said that the heavens will descend on the people, and they must first work their muscles and bones, starve their bodies and skin, and suffer their minds......"

No, it doesn't make sense for you to say this, mother.

I'm just a eunuch, okay?

But I don't want to take on any big responsibilities at all, whoever likes to be should go!

It's rare to cross once, I just want to be glorious and rich, enjoy wantonly, have a beautiful wife and concubine, and live a lifetime with left and right hugs.

It can be seen that the queen is not my confidant, if you are like this again, I will not be rare for you!

"I'm just a little eunuch, but I don't have any great ambitions...... In short, this eunuch is too depressed, so it is better to simply quit and concentrate on serving Niangniang. ”

"Nonsense, this is sealed by the emperor, if you don't want to do it, don't do it? But I told the emperor, you still serve as the head of Kunning Palace......"

I can't bear you.

Murong Danqiu glanced at Xiao Chen's lower body as he spoke, and suddenly his cheeks were full of peach blossoms.

"Really? It's so good, it's mainly because the minions are reluctant to let you go. ”

Xiao Chen immediately captured the deep meaning of the queen, and immediately leaned over to say something affectionate to her.

Who knows, the eunuch outside suddenly came to report, saying that the prince came to ask for peace.

Murong Danqiu frowned slightly, gently pushed Xiao Chen, and then said lazily: "Let him come in." ”

"Then the minions will retire first?" Xiao Chen said busily.

"Don't go, stay here with me." Murong Danqiu's expression was a little strange.

"Son, please Empress Sheng'an!" The crown prince Li Xian held his head high, strode in, and bowed to Murong Danqiu.

"Excuse me." Murong Danqiu's voice was cold.

It seems that he doesn't treat this prince very much.

"I haven't seen her for a few days, and the queen is getting more and more vibrant." The crown prince raised his head with a smile and stared at Murong Danqiu intently.

That's a bit of a faux pas.

"The prince is busy with official business, and the palace won't keep you much, Xiao Chen, send the prince out for me." A trace of anger flashed in Murong Danqiu's eyes.

"Erchen misses the queen very much, how can he give an expulsion order when he meets, he is really a ruthless person." Prince Li Xian's words were almost joking.

It's not rude, it's rude!

Equivalent to flirting.

Xiao Chen, who was watching coldly, was greatly surprised.

Could it be that this prince actually has any bad thoughts about the queen?

Damn, that's too much!

It's a beast!

He took a step forward, bowed down, and said loudly: "His Royal Highness the Prince, please!" ”

The prince glared at him fiercely, but he didn't get angry, "The minister will retire first, and then come back to greet the queen." ”

"If the prince is busy, he doesn't have to come."

"If you want to come, if you don't see the queen mother for a few days, your son's heart will not be steady."

"Prince, please!" Xiao Chen's teeth itched when he saw his hippie smiling face, and he almost couldn't help but fly up and kicked him out of the palace gate directly.

Outside the palace gate, the prince stopped and stared at Xiao Chen, his expression unkind.

"Xiao Chen, do you think that if you have made a small contribution to your father and the emperor, and you can despise the lonely king by relying on the queen's waist?"

"Minions don't dare!" Xiao Chen was shocked when he heard this, and the chrysanthemum tightened.

What the? Why are you coming at me?
