[Comprehensive] The painting style of time travel is wrong

Many things are like this. To put it bluntly, the principle is very simple, but before the layer of window paper is pierced, it is a technological gap. It is a problem that countless wise men of that era have racked their brains and cannot solve. It is a roadblock in technological development. The Himalayas are the Mariana-like deep ditch on the way of human progress.

This is just like the four great inventions of ancient China, in the eyes of modern people, they are "primitive technologies" without technical content, but at that time, these were accumulated by countless top wise men of that era for generations, plus geniuses. The great achievements born only by coincidences in flash or probability are the prerequisites for the development of countless advanced science and technology.

In other words, before the millennium now, those "primitive" technologies were secret methods!

However, when Tang Xuening saw the four wizards who became famous thousands of years later, the faces of the four were very bad.

In fact, the girl's complexion is not very good, but maybe she got used to it after a long time.

The reason is very simple - girls are really smelly now (Note 1)...

Even though the formula of fire/powder may be known to most Chinese, but knowing the formula is not enough, you must have raw materials!

Charcoal can be homemade, sulfur is expensive but not impossible to buy, but the remaining raw materials are a problem.

Even in order to guard against the next attack by the local brain-dead nobles, the girl had already prepared for it a long time ago, but if you need it temporarily, you still need to get it, right?

And the original nitrate technology is indeed full of things that cannot be said while eating...

The luck in misfortune is that the four wizards are relatively well-educated, even though Salazar has some criticisms about this:

"I finally know why those Muggle wizards are called 'Mudbloods', it's a compliment."

But when several people came to visit, they still smiled.

——After all, the ingredients of some potions are disgusting to think of, others are disgusting because of the smell they emit, and even some raw materials and smell are disgusting.

What's even more frightening is that in many cases, wizards have to drink those disgusting potions to take effect!

—In this day and age, death from potions is said to be one of the common leading causes of death among wizards.

"Okay, let everyone see what you want first."

Although no one revealed the shortcomings, but seeing the forced smiles of several people, the girl quickly got to the point.

After hearing the girl's words, the few people no longer struggled with the disgusting smell. They followed the girl's arm and looked towards the hillside about a few hundred steps away. There was a small open space that had been cleared out.

On the open space are seven or eight tied scarecrows and wooden planks that imitate armor covering the scarecrows.

"I don't know if such a quantity is considered a large number?"

The girl asked several wizards, and after getting an affirmative answer, she lit a rope beside her with a torch.

Under the slightly surprised eyes of several people, a small flame quickly burned along the rope to the distance.

Finally, the girl reminded while throwing down the torch:

"Wait, please cover your ears!"

"boom!"

After a moment of silence, accompanied by a huge roar like summer thunder, dazzling flames and mud shot up into the sky, mixed with several shattered scarecrows and countless large and small stones flying into the air.

One of the benefits of technology is that if the power is not enough, it can be made up by quantity. Even if the girl knows how to convert the explosive equivalent of the nuclear bomb reaction material, she is still not sure about the specific power of the earthen powder she made by hand.

And in order to make the wizards feel "useful", the girl frenziedly buried nearly [-] kilograms of gunpowder hoarded over the years in one go, and the effect was good—or a little too good.

The trees closest to the explosion point fell radially to the surroundings. Even where a few people stood thousands of steps away, it seemed as if a light rain of dust and various debris fell. Everyone present felt that they were being hit by an invisible sledgehammer. Knocked on the chest, and all kinds of fragments splashed out made the few people who were completely unprepared into a mess.

The strong tinnitus (Note 2) caused by the explosion lasted until the smoke column of the explosion slowly rose into the sky, and then it got better.

"I... I feel as if I was yelled directly in my ear by a troll..."

Helga was the first to speak while supporting the tree trunk beside her.

"Now it seems that there is a swarm of bees around my ears..."

"Ha...haha...so funny..."

On the other hand, Rowena stumbled to his feet and tried to walk to the center of gravity to have a look, but within two steps, he had to grab a tree trunk and retch.

"Wow, it's really a valuable secret technique..."

Godric shook his head vigorously, shaking off a lot of various debris.

"How did you do it?"

"Haha... that's... a secret."

Tang Xuening was the first to recover by relying on her previous battlefield experience, but now she looks quite embarrassed.

"Who is that over there? How is it? This secret method is useful for wizards."

"Um……"

Salazar's current state is also very bad, just looking at him shaking twice even when he is holding on to the trunk.

So it was not until a long time later that he went on to say:

"The power...the power is good, but...when facing the enemy...they won't just stand there and wait for you to use...use your secret technique."

"There are some that can be used immediately, but it will take time..."

The girl answered while plucking a twig from her hair:

"The current science is only a baby if we want to compare it. It can only show you its potential first."

"Baby?"

After receiving this reply, Salazar put his head directly on the tree, and it could be seen that he was really dizzy now.

"Okay, if you think this is valuable, can you trade it?"

The girl finally asked after patting the dust off her body.

"Can it be replaced by something else? Like a potion that lets you pretend to be someone else or get lucky?"

The first to respond to her was Godric, who was in the best condition among them:

"As far as I know, there is no magic or creature that can make people live for 1000 years - some legendary dragons or elves (Note 3) may be able to, but others, not even goblins can do it."

"Can't do it? I remember that there is a magic stone that can make people live forever?"

The girl who was stunned by this answer asked quickly.

"The Sorcerer's Stone? What's that?"

Godric asked suspiciously.

"Wait... wait, I seem to have heard of it, let me think about it..."

It was Rowena, who had already recovered, who intervened in the conversation, and then she yelled in surprise.

"By the way! Are you talking about the alchemy in Persia or the alchemy in the far east!? Someone really succeeded in refining red stone (Note 4)!?"

"Hmm... so no one has practiced this game yet?"

The girl suddenly realized that she might have made a mistake. Unlike the general myths of cultivating immortals, the older the stronger, it seems that the magic of wizards is developing step by step with the times. That is to say, in this world 1000 years ago, magic It may not be as powerful as it will be in the future-this can be seen from the fact that wizards are still unable to fly.

But then she recalled another possible way of living 1000 years in the original work:

"And vampires? Can you make me a vampire?"

"Uh... It seems that the British Isles haven't heard of vampires for many years..."

Godric twitched the corner of his mouth and expressed himself in the most tactful way possible.

"And even if you find out that there are many restrictions on 'First Embrace' within the vampires, it is very likely that you still cannot achieve your wish..."

In fact, if Salazar answered, then his answer is estimated to be:

——Muggle, you need to understand your identity, you can be a vampire if you want? ——

"So……"

The girl scratched her head and began to recall desperately, looking for any clues that might realize her thousand-year plan in every corner of the memory.

"That's interesting. It's true that no magic is used and it's not a potion. It's charcoal...sulphur...and the dirt from graves or rotting corpses? Is it some kind of branch of necromancy?"

But before the girl could remember anything, there was a "breakthrough" on Rowena's side.

I saw her use her fingers to grind the embers left by the fuse/fire/cable just now, and after looking at it, she put it down under her nose and smelled it, and then asked a very puzzled question:

"No... No, no magic power was used... Is it some kind of summoning technique that attracts the power of the flame demon in the legend?"

"..."

The girl was speechless for a while.

——Sister, how can you let other people live by being so fierce. ——

"By the way, why do you have to live until 1000 years later?"

Helga, who was wobbling on the other end, asked curiously as if suddenly remembering something:

"If you just want to live longer, don't those nobles, kings, etc. generally say 'immortality'?"

"After a thousand years, I need to do something very important to my destiny!"

——It's really very important. Once I fail, I will become the subject of research in various research projects!God knows what research content those weird aliens can come up with, the only woman on the handsome planet is okay, what if it is a "human with a tip of the tongue"! ? ——

"Are you a prophet?"

"Is there really no other way for you?"

This time the girl completely ignored Helga's question and turned to look at the others.

"Maybe I can help."

Under the expectant gaze of the girl, Salazar, who seemed to have recovered, took a step forward and drew out his wand.

"Petra!" (Note 5)

"gos!"

Accompanied by two loud shouts and an instant flash of light, the collision of the two spells just now seemed to be just an illusion if there was no clear trail left by the light in the field of vision.

"Godric! What are you doing!?"

Salazar shouted angrily at his friend.

"I'm preventing you from doing the next wrong thing!"

Godric, who didn't know when he drew out his wand, walked slowly and blocked the girl behind him.

"Wrong thing? No, I'm doing the right thing!"
