"Remember to apologize to Mel later, you know? He is now our friend. Pen & Fun & Pavilion www.biquge.info"

Coming to the door of one of the closed rooms, Jiang Liu'er thought about it and didn't forget to add this sentence.

"It's all out to be thieves, what kind of archway to build, why didn't you talk to your mouse friend at first......"

Lingxiu muttered to herself, pursed her lips, and waved her hand casually: "Okay, okay, I know." ”

There was a copper lock hanging in front of the house, which, of course, did not stump our Monkey King.

I saw Lingxiu conjure up a fork and pounded it twice, and then only heard a "click" sound-

The door lock was easily opened.

It seems that she used to do this kind of thing before, and it is said that Taishang Laojun's elixir was stolen by her like this.

After the door was opened, Lingxiu conjured up a bright oil lamp, and suddenly the scene inside the house suddenly became brighter.

You can vaguely see a lot of strange things placed inside.

It's all black, lumps of balls, neatly arranged.

"What are these?"

Lingxiu grabbed a piece casually, took it in the palm of her hand and rubbed it, and immediately stuck her black hand, so she quickly threw it away.

Jiang Liu'er didn't feel dirty, grabbed a piece and looked at it carefully, and sniffed it on the tip of his nose.

Then the eyes lit up: "Is this coal, or is it a finished product after washing and separating impurities with water!" ”

Coal, in fact, has been used in the previous dynasties of the Tang Dynasty, and it first appeared in the Western Han Dynasty, but due to the high cost of mining, it is easy to have mine accidents (water penetration accidents and gas explosions), resulting in the use rate and promotion rate of coal is not high, and finally only rich families can use it.

Ordinary people still continue the tradition of using "firewood" as fuel for eating and boiling water.

I seem to remember that when the Tiger Pioneer General was promoting the law, he once mentioned the matter of "coal mining".

The mining industry in Huangfengling is still very advanced.

"Coal? What is coal? Lingxiu blinked, she didn't know what these black things were.

"Coal is ......"

So Jiang Liuer enthusiastically explained to her the birth, composition, and use of coal.

"After doing it for a long time, it turned out to be a fire......"

After listening to the master's explanation, the girl suddenly lost interest and pursed her lips: "So, what's the use of this thing?" ”

Well, she knows how to do magic, and of course these monsters should all know how to do magic.

At least that's what she thinks.

Everyone knows spells, and as long as they encounter difficulties in daily life, a "xx supernatural power" will be solved in the past.

What a convenient thing!

So, now the question is.

What is the use of these fire-burning things?

Jiang Liu'er didn't speak, and he didn't care about what this apprentice said, in fact, he was already too happy to know why.

Because, for the first time, he saw the real "coal" in this world.

Coal, in his impression, is not only for fire, but also for further civilization.

"Let's go to the other rooms!"

He dragged Lingxiu's hand, and regardless of the black coal sticking everywhere on his hand, he just walked out the door.

“……”

Jiang Liu'er's temperature came from his hand, and Lingxiu moved his mouth, but he still didn't say anything.

Well, although she didn't rule out being caught by the master like this, the girl still decided to wash her hands when she went back.

The two of them went to the second room and unlocked the door as they did.

Then came the aroma of mugs and sausages.

It seems that this room is the legendary "treasury" - Huang Fengling is bartered.

There's nothing to explore in the treasury, just something to eat, but these cured meats and sausages obviously have some processing steps and can be stored for a long time, and these technical monsters can't have them, and they should have been taught to them by Mel - of course, before leaving, Lingxiu didn't forget to grab a sausage to nibble on, she didn't have enough for dinner.

Then there was a third room, still open.

This room is more peculiar.

There were some messy parts in it, scattered all over the place.

Most of these parts are made of steel -

Steelmaking technology has long been available in the Tang Kingdom, and Mel must have learned it from there.

And then look at what these parts look like.

Pipes, plugs, wheels like windmills, a big boiler......

"It's a steam engine! Mel is inventing the steam engine! Jiang Liu'er was so excited that she couldn't control it and shouted.

Lingxiu on the side hurriedly covered his mouth with his greasy hand: "Shhh, Master, be quiet, you will be heard!" ”

The greasy hands had just eaten sausages, and of course, the girl didn't care about that, she couldn't wait to touch the master with both hands.

"Oh, I'm sorry, I can't help it."

Jiang Liu'er controlled her emotions, immediately calmed down, and used a lot of strength to remove Lingxiu's hand that was covering his mouth.

But the excitement in my heart has not been eliminated.

As soon as he entered the first room, he had a hunch that Mel was quietly making a big deal.

Now it seems that he has lived up to his expectations, and Mel is really working on something new.

Something that is simply impossible in this era.

What does the steam engine represent? It represents the industrial revolution and represents a new era.

The China in the dream, as well as the Tang Kingdom where he is located, have all been in a feudal society for thousands of years.

What does feudal society represent? It represents the ox in the plough, the horse in the cart, and the firewood for boiling water.

Jiang Liuer once had the idea of inventing the steam engine.

However, this step is not so easy to achieve, first of all, to design the drawings, to draw the patterns of various instruments, to calculate the internal force area of the steam engine, the pressure, etc., then to start the manual collection of materials, to manufacture according to the drawings (this requires manual supervision, it takes a long time), and finally to test the finished product - anything is not made and can be used, and it has to go through hundreds of thousands of failures.

As with glass, unless you have a lifespan like Mel's, you have to have enough time to teach a group of people first.

Otherwise, it will be difficult for individuals to do it, and this needs to be organized by manpower.

Even Edison, who invented a light bulb that looks simple to modern people, was not alone in the laboratory, messing around like a madman, but with an "Edison team" with dozens of people behind him to support him as assistants, and these assistants are smart people from all walks of life and are highly educated.

Unexpectedly, now Mel actually took the lead, which really made Jiang Liu'er sigh.

It is said that the brains of rats are very different from the brains of humans, and rats can think of things that many people can't think of, and praising a person for being smart can generally be described as "you have a brain like a mouse".

Facts speak louder than words, and it can be seen that this steam engine is still in the process of research and has not been used for practical purposes.

But this is already proof that Mel, the Rat King, is expanding into realms that humans can never imagine.

Well, Jiang Liuer feels like -

This friend of his, it may be better to be an inventor than a politician.
