[Comprehensive] The painting style of time travel is wrong

When the four of them were invited into the huge tree house by Tang Xuening, the "sage of the earth", they realized that compared with the huge appearance, the inside of the tree house was actually quite small - not because of how thick the outer wall was, but because The girl stuffed it full with all kinds of sundries.

Countless things they could name but couldn't name were piled up on rows of wooden shelves rather crowdedly, and between the wooden shelves were placed all over the place with strange shapes and useless wooden or iron components.

A hollow iron pipe as high as a person on the ceiling circles around the house, a wooden water turbine and an iron-making furnace with orange-red flames are at the other end of the room, and Yin Hong’s iron blocks are still on the iron felt next to the furnace , Seeing these few people finally understood why the girl seemed so impatient when they came to visit.

On the other side of the door, there are a huge number of "bark" hanging on the wooden frame, with all kinds of weird but regular patterns and dense markings drawn on them, which almost makes people feel dizzy at first glance. The "secret sign" - all this makes the black-haired girl look like a legendary mysterious alchemist.

Several people in this "hut" that is obviously beyond the current era, with the permission of the girl, several people quickly found something they were interested in.

Rowena showed great interest in the hanging blueprints, Helga admired the porcelain piled up in one corner with a surprised expression, and Godric was curious on the other side Looking at the various iron pipes and bearings on a row of shelves.

"You've done a pretty good job of being a liar, and if you weren't a Muggle I'd probably believe you were a really powerful wizard."

However, Salazar, who decided that the girl was just a liar, snorted coldly. He just looked around and asked the girl directly:

"Science—well, if it's not something you made up to deceive us, but it's real. So what does the arcane do?"

"Well...can do a lot of things."

A small bench was cleared out of the messy "garbage". After seeing the other party's disgusted expression, the girl simply sat down, thought for a moment and replied to Salazar:

"Produce tools, cure disease, increase food production...it can do a lot of things that lead to productivity improvements."

"Productivity (Note 1)? What does that mean? Are you referring to your alchemical codes?"

Rowena, who was holding a piece of sheepskin and trying to decipher the "signatures" on the drawing, heard this, and walked over curiously to join the conversation.

"I've never seen such a complex and difficult to decipher code before, maybe we can communicate in this regard."

Yes, in that era when the value of knowledge was unparalleled, in order to ensure that their research would not be obtained by others due to theft or other reasons, scholars and wizards always liked to use various inexplicable codes to "encrypt" their achievements.

However, the girl here has nothing to do with the issue of confidentiality, but she feels that it is difficult for her to explain to an ancient man thousands of years ago what advanced mathematics and relativity formulas are, let alone the further time theory after this—even if the person who asked the question In the original, it is known for its wisdom.

On the other hand, the girl admitted that she herself only learned these theories and formulas from the previous world, as for how she derived them and how to explain this theory to others...

Hahaha, the weather is really nice today.

"Um……"

The girl hesitated for a moment, how to explain the concept of "productivity" in the simplest way, thought for a while and said:

"Think of it as a power that earns lots and lots of gold."

"gold?"

Salazar sneered again, waved his wand and tapped lightly on the pile of debris around him.

Then, under the surprised eyes of the girl, a small pile of neat gold coins appeared there.

"You mean this?"

"Wait... wait, I remember..."

Feeling that her three views had been impacted, the girl subconsciously just uttered the words, and suddenly remembered something and closed her mouth suddenly.

Let’s not talk about the consequences of not being able to tell the “original work” to a few people. Just the five exceptions to the basic law of Gamp’s transformation deduced by countless movie fans (Note 2) are full of loopholes if you think about it carefully—— Though it shouldn't exist in this day and age.

Yes, even if the Transformation Curse really can't change gold and silver, can it change banknotes?

Are banknotes any different from pieces of paper to wizards?

You must know that Muggles' shopping can also be exchanged for the gold and silver used by wizards!

If this is the case, then the financial collapse of the wizarding world is at most as bad as the Gringotts exchange procedure.

——But if you think about it this way, then there are problems with those who rely on the difference in the price of gold between the wizard and the mortal world to make a lot of money, and even go further and want to use this method to kill the economy of the wizard world! ——

The girl suddenly opened her mind:

[Facing the influx of "Muggle" currencies, the deflation in the market of a large amount of gold that has been taken away, and the cross-travelers who are triumphantly trying to control the wizarding world in this way, the wizards smiled slightly, and turned into a big Pile banknotes into tons of gold—come on, hurt each other, and see if the outside shoppers turn into waste paper first or the wizard’s finances collapse first, who is afraid of whom~]

But thinking about it this way, the two rebellions (Note 3) in history of the goblins who are responsible for managing Gringotts-controlling the finances of the wizarding world are also full of shady scenes.

What did Kissinger say about the comer?

——Whoever controls the right to mint currency controls the world.

Think carefully! (Note 4)

"So can science do anything we can't?"

Just when Salazar was suspicious of the girl's reaction, he frowned and was about to say something.

Curiously playing with an iron pipe, Godric, who made a crisp sound with his sword from time to time, walked over and curiously inserted into the conversation:

"For example, can science make people fly?"

"of course can."

The girl held her head high and nodded amidst the surprised expressions of several people.

"really?"

Hearing the news, Godric's eyes seemed to light up.

He ran over with surprise on his face and said happily:

"Although none of the magic I know can make you live for thousands of years, but I can..."

"Wait a minute, Godric."

Salazar interrupted his friend, and he asked the girl:

"So what's the price to pay if you use the 'scientific' method to fly?"

"Proper training and plenty of fuel."

The girl answered.

"that's it?"

Godric, who had calmed down, asked back with some doubts.

Bravery is not the same as recklessness. In this era without St. Mungo's healer, a stupid and reckless little wizard will not survive to adulthood.

"Is there really no need for other conditions?"

"let me see……

Maybe...probably...there are still five to ten years of special development—unlucky and a few more years, a population of about a few thousand people...

Wait, looks like I don't remember any oil fields in mainland England...

Then it may be necessary to buy some kerosene from Byzantium for refining and processing..."

The more the girl spoke, the lower her voice was, because she saw the expressions of "you're joking" from the four people on the opposite side.

——There is no gene lock, no base vehicle, and no optical brain. The development of science has always been a process of accumulating, and the early development is so slow. Moreover, building aircraft, even if it is only for manufacturing aircraft, requires some pre-technology ?

——Requires high-strength metal, high-strength metal processing and forming technology, oil exploration and refining technology, rubber sealing technology...

——Even if you know all these technologies, you still need workers who mine ore, workers who screen ore, workers who are in charge of casting, and workers who can understand your drawings and reproduce them with steel!

——You need to train these workers one by one, if you can give them time to familiarize themselves with honing their skills, if you can provide them with enough food, shelter and even remuneration!

[Those powerful people who have developed steam engines and steam engines in ancient times in more than ten years, can you talk about your experience?Wait online, hurry up! 】

"Well ... it should be possible in ten to 15 years."

"How long can it fly? How far? How high?"

Compared with his three-dimensional companion, Godric seems not to give up on this opportunity that allows him to fly.

"Does the magic power consume a lot?"

"No magic power is required at all! But the original plane that has been developed in the past ten years can also fly..."

The girl decided to tell the truth with a bitter face.

"Probably a little higher than my house, flying about a few hundred breaths and about [-] steps away."

In this era of development for more than ten years, it is already very huge to be able to manufacture an aircraft of this level, which is enough to stand shoulder to shoulder with the four great inventions of ancient China.

In other words: this kind of aircraft may not be built yet...

"Oh……"

Judging by Godric's expression, it was obvious that he was not interested in science after hearing what the girl said.

"So can 'science' create hallucinations, make people forget what they saw or hear, or treat someone they just met as a friend?"

Seeing that the two men were silent, Rowena stepped forward and asked curiously.

"Or go a step further and allow me to see other people's memories?"

"...Under normal circumstances, this should not be possible within 100 to [-] years..."

The girl replied reluctantly.

——Even if you do *experiments frantically regardless of human ethics and morality, you must first point out electromagnetic technology to achieve imaging brain.

"Fifty to 100 years..."

Rowena obviously has no interest anymore.

"Can conjure food or make food taste better?"

Helga asked at last.

"Although you can't 'change' the food, you can make the food taste better..."

Yes, various chemical flavoring agents can create delicious tastes that the ancients could not imagine, but the same problem is also obvious.

Thinking of Sudan Red, melamine, and plasticizer, the girl added to the somewhat happy honest man in front of her:

"However, it is not recommended that you use 'scientific' methods to make food taste better—damn it, I knew that I should have focused on cooking while studying technology!"

"why?"

Helga asked curiously.

"It's not very good for your health..."

The girl answered with a stiff expression.

When the girl finished speaking, the whole room suddenly fell silent.

"I admit that you have a lot of interesting gadgets here, and I am willing to exchange gold and silver with you, but the one in your mouth..."

Godric tried his best to ask the questions on the minds of the wizards on behalf of the wizards in a non-aggressive tone.

"But what's the use of science anyway?"
