The sand spread out, revealing two iron pipes inside.
The original two iron pipes have been welded together.
The craftsmen worked quickly and in a short time, they connected all the iron pipes together and connected them to the pipes at both ends of the hot water heater.
Then, Li Ke directed a dozen craftsmen to carry a box outside the Tai Chi Hall.
The box was as tall as two people, and there was a huge iron pot on top. There was an iron pipe diagonally below both ends of the iron pot, extending down and connected to the iron pipe on the left side outside the main hall.
Under the big iron pot, there is a huge stove.
Li Ke gave the order, and the craftsmen began to light the fire.
Everyone was stunned.
At this time, Li Ke came over and said, "Father, my lords, it's cold outside the hall, so you should wait inside the hall. In half an hour, it will be as warm as spring inside the hall."
Li Er and others walked into the Tai Chi Hall with curiosity. Although the craftsmen were sweating profusely due to their busy work, the others standing aside had their legs and feet numb from the cold.
When everyone walked into the hall, they only listened to Li Er's instructions: "Someone, please remove all the braziers!"
In order to see what Li Ke was up to, Li Er also risked his life.
Feeling sorry for Quan Wanji, he started eating snot again.
Everyone only heard Li Ke's voice coming from outside.
"Add charcoal! Make the fire louder."
"Release the water!"
"Change the water!"
"Let the water go..."
Immediately, the ministers in the palace felt that the four iron monsters placed around them were emitting heat. Someone touched them lightly with their hands, only to find that the iron monsters were very hot to the touch.
In a short time, the entire hall became warm.
Half an hour later, following Li Ke's order, the doors and windows in the hall were closed. It didn't take long for the entire hall to feel extremely warm.
This kind of warmth is different from roasting charcoal fire. When you roast charcoal fire in cold weather, your front will be hot, but your back will be extremely cold. In the entire hall, only the brazier is warm, and it will not affect other places at all.
, because this hall is really too big.
But now, the four iron monsters are emitting heat, making the entire hall feel as warm as spring.
Li Ke walked in and said proudly: "Father, I succeeded!"
Everyone was speechless.
Just now, everyone thought Du He and Li Ke were bragging, but with the facts in front of them, no one dared to issue any further orders.
On the contrary, everyone was very surprised by Li Ke's set of things.
This is a good thing that no one has ever seen before.
Li Er was also very curious and asked: "Ke'er, what is that thing you put in the hall? Why does it generate heat?"
Li Ke said: "Father, this is the hot water tablet developed by the teacher, Erchen and others. It is specially used for group heating in winter. This hot water tablet is very convenient, has balanced heat, and is safe. It will not cause the problem of brazier heating."
It accidentally caused a fire, and it is very clean and does not leave any dust!"
Everyone nodded in agreement.
With more than a dozen braziers in the Tai Chi Hall, white specks will appear on the heads of many people within a short period of time, but this hot water tablet avoids this situation.
Furthermore, fires occur in Chang'an City every winter. The cause of the fires is very simple. Even if the government gives repeated orders, there are still many people who accidentally light their houses on fire while baking charcoal fires, and even burn themselves.
As soon as the hot water tablet appeared, these two big problems were solved.
However, when Li Er saw that his Tai Chi Hall had been covered up beyond recognition, his mood was not so beautiful.
He turned to look at Du He: "Du Qing's house, this hot water heater is a good thing, but... it looks a little rough. Also, it looks rough in workmanship. Can you think of a way to change it?"
Du He stood up and said: "Your Majesty, this set of equipment was specially built by me to give to your Majesty. It costs a lot of money. Of course it is no problem to change it, but... I have already spent all the money of the Dream Group.
Ku, for the time being...I'm afraid it can't be changed."
Li Er and others all widened their eyes.
"Marquis of Huyi County, how much does this hot water tablet cost?" Someone asked in surprise.
Du He waved his hand: "First of all, this set of equipment is not much. It costs 3,000 yuan. It is mainly for research and development. In order to develop this hot water heater, I spent a full month and led fifty craftsmen around the clock.
, a total of fifty sets of optical equipment have been built... The research and development expenses, when added up, are actually not much, just two hundred thousand yuan."
Two hundred thousand dollars?
Not much...
Actually not much...
Everyone wanted to beat Du He to death.
This guy's expression really deserves a beating.
However, this thing is unprecedented after all, and it doesn’t matter if the research and development costs are high. Everyone can understand it.
Li Ke, on the other hand, was so shocked that he could not speak.
Others don't know it, but he is very familiar with the research and development process of this hot water tablet.
This thing was actually developed by Du He, Yuan Qingfeng, Lu Hao and him, a total of four people, in less than two days.
The whole process cost less than 3,000 guan.
The equipment in front of me was also built overnight by the craftsmen of the R&D center. It was very rough and cost only about 500 guan.
This Du He...is too bragging?
However, he didn't have the guts to expose Du He on the spot.
As he spoke, he said with a smile: "Father, gentlemen, I guarantee that what the teacher said is true... Don't look at the ugly appearance of this hot water tablet, it represents the highest level of Datang's technology."
At this time, Wei Zheng came over, rubbed his hands, and asked: "Du He, so you can install your hot water heater in my mansion?"
Du He nodded: "Master Wei, you are really smart. You can see the function of this hot water heater at a glance. Yes, this hot water heater is designed for people to warm up. It can eliminate the need to build different houses of different sizes.
You can also put one or several hot water tablets, but the price is naturally much higher."
"How much does an ordinary main house cost?"
"At least two thousand strings."
Snapped.
Wei Zheng slapped his thigh and said: "I bought it... I have always had the habit of reading at night. The weather has been cold recently. Although the brazier can keep me warm, after a long time, I feel dizzy. The most important thing is that it makes me feel dizzy.
Several of my robes had big holes burned out. When it was really dangerous, I now have this hot water heater, which is tailor-made for me. I decided to install one for the study in my house even if I wanted to sell it.
"
Wei Zheng was an upright official, and he didn't care about making money. His family was not well-off, but when he saw the great effect of this hot water tablet, he resolutely decided to do it.
When everyone heard this, they reacted one after another.
Yes, such a good thing is much more advanced than the brazier. If I don’t buy a set of two for my house, I will not be able to live up to my high status in the court.
When Du He saw this, he thought to himself, this is all business!
