God-level Consort of the Tang Dynasty

Inside lay four icy-looking iron monsters, which were as tall as a person when they stood up. There was an iron frame outside, and thin iron pipes wound back and forth more than 20 times in the shape of a snake inside. It looks very ugly, like crooked melons and jujubes, and has no aesthetic feeling, so it looks like an iron monster.

This is the hot water tablet.

At the bottom of the hot water chips, there is a nozzle respectively.

Under Li Ke's command, the four iron monsters in everyone's eyes were moved to the Tai Chi Hall and placed in the four corners.

Then, the craftsmen carried the iron pipes one by one into the Tai Chi Hall, and simply connected the two previous iron pipes with the hot water sheet.

Li Ke turned around and looked at the blazing flames from the earthen stove under the steps. The pig iron in the earthen pot had turned into molten iron. The bottom was red, but blue flames had already burst out from the surface.

For some reason, Li Ke felt a little nervous.

He turned to look at Du He.

Du He stood by the pillar, smiling and nodding at him.

Encouraged by Du He, Li Ke's mood suddenly calmed down, so he shouted: "Get out of the way!"

Everyone hastily stepped aside.

I saw six craftsmen, using three wooden sticks to pass through the ears on three sides of the big earthen pot, and working together, they quickly lifted the earthen pot up.

In the clay pot is full of molten iron.

The craftsmen walked into the Taiji Hall, and Li Er and others followed suit.

I saw that at the place where the two iron pipes were connected, several craftsmen had been waiting, and they had already wrapped the connection with a wooden box.

A craftsman stepped forward, took out a huge wooden ladle, and poured molten iron into it three times in succession.

The wooden box burst into flames, emitting a puff of blue smoke, and there was a pile of sand inside.

……

(Thanks to [Xi Youhuahe] [21. The Mark of Little Happiness] brothers for their rewards, and thanks for their support!)

Chapter 483 It's All Business

The sand spread out, revealing the two iron pipes inside.

The original two iron pipes have been welded together.

The craftsmen were quick with their hands and feet, and in a short time, they connected all the iron pipes together and connected them to the two ends of the hot water sheet.

Then, Li Ke directed more than a dozen craftsmen to carry a box to the outside of the Tai Chi Hall.

The box was as tall as two people, and there was a huge iron pot on top. The two ends of the iron pot were slanted downwards, and there was an iron pipe extending down to connect with the iron pipe on the left side outside the hall.

Below the big iron pot, there is a huge stove.

Li Ke gave an order, and the craftsmen began to light the fire.

Everyone was stunned.

At this moment, Li Ke came over and said, "Father, my lords, it's cold outside the hall, you'd better wait in the hall. After half an hour, I will ensure that the hall is as warm as spring."

Li Er and the others walked into the Taiji Hall with curiosity. Don't look at the busy craftsmen sweating profusely, but the others stood aside, but their legs and feet were numb from the cold.

Everyone walked into the main hall, only listening to Li Er's order: "Come here, remove all the braziers!"

In order to see what the hell Li Ke was up to, Li Er also went all out.

Poor Quan Wanji, he started eating snot again.

Everyone could only hear Li Ke's voice coming from outside.

"Add charcoal! Bigger fire."

"Let the water go!"

"Change the water!"

"Put the water..."

Immediately, the ministers in the hall felt that the four iron monsters placed around were exuding heat. Someone touched them lightly, but found that the iron monsters were very hot.

In a short time, the entire hall became warm.

Half an hour later, following Li Ke's order to close the doors and windows in the hall, it didn't take long for the entire hall to be extremely warm.

This kind of warmth is different from charcoal fire. In cold weather, the front of the charcoal fire is hot, but the back is extremely cold. In the entire hall, only the brazier is warm, and it does not affect other places at all. , because this hall is really too big.

But now, the heat emitted by the four iron monsters made the entire hall 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 say anything.

On the contrary, everyone was very surprised by Li Ke's set of things.

This is a good thing that everyone has never seen.

Li Er was also very curious, and asked: "Ke'er, what is it that you put in the hall? Why does it have a fever?"

Li Ke said: "Father, this is the hot water sheet researched by the teacher with Erchen and others. It is specially used for group warmth in winter. This hot water sheet is very convenient, the heat is balanced, and it is safe. There will be no brazier heating. Accidentally start a fire, and it is very clean without leaving any dust!"

Everyone nodded in agreement.

With more than a dozen braziers in this Taiji Hall, white flakes would appear on many people's heads in a short time, but this hot water sheet avoided this situation.

Moreover, fires break out in Chang'an City every winter. The reason for the fires is very simple. Even with repeated orders from the government, there are still many people who accidentally set their houses on fire while cooking charcoal, and even burned themselves.

As soon as the hot water tablet appeared, it solved these two big problems.

However, when Li Er saw that his Tai Chi Hall had been covered beyond recognition, his mood was not so beautiful.

He turned his head to look at Du He: "Du Qing's family, this hot water tablet is a good thing, but... it looks a bit rough, and 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 as a gift to His Majesty. It is expensive. Of course, it is no problem to change it, but... I have already exhausted the money of Dream Group. Ku, for the time being...I'm afraid it won't change."

Li Er and the others all stared wide-eyed.

"Houyi County Marquis, how much does this hot water tablet cost?" Someone asked in surprise.

Du He waved his hand: "Let's talk about this set of equipment first, it's not much, and the cost is 20 guan. It's mainly research and development costs. In order to develop this hot water tablet, I spent a full month with fifty craftsmen without sleep. , A total of [-] sets of optical equipment have been built... The research and development costs, added up before and after, are actually not much, just [-] yuan."
