"I can't seem to wear this mirror." Ian's palm was pressed against the mirror, which rippled like water.

"Hey! You little brat! Are you listening to me? Don't ignore me! The girl on the other side shouted.

"Let me introduce myself, my name is Ian, and I work on the farm, but although I say it's a job, I'm actually a slave, and I was sold to the farm." Ian sits cross-legged with his hands on his knees.

"Forget it." The girl suddenly calmed down: "This, probably a dream, really, even dreams are so strange, wake up quickly, I have to go on a date with Mr. Blessing tomorrow." ”

"Blessings?" Ian felt the name familiar.

"It's obviously the person in my dream, and you forgot about Mr. Blessing?" The girl held her forehead and sighed: "Okay, I'll tell you with great mercy that Mr. Blessing is the person I like, mature and handsome, and very talented, and an ideal gentleman." ”

"Mr. Blessing, do you like you?"

"It's too early to say this, and when I also grow into a mature woman, Mr. Bless will definitely fall in love with me!" The girl raised her face and said confidently.

"You... Could it be Asuka? Ian felt that the girl's voice and appearance resembled that of a woman he knew.

That woman is one of the heroines of the famous anime "Neon Genesis Evangelion", Asuka as the pilot of the second plane, although she has a bad temper, but a veritable genius girl, is a character that Ian likes very much.

Perhaps, he was dreaming because of too much pressure.

But is it really a dream?

There is indeed a hazy feeling of dreaming, but such a lucid dream... It's weird...

"I'll just say it's a dream." Asuka confessed her identity: "It's not my dream, how can you know my name." ”

"You're right." Ian responded.

This should be the EVA No. 2 pilot he is familiar with, in his opinion, treat Asuka as much as possible with her, otherwise it will make things very stiff and may quarrel for a while.

He didn't want to quarrel with Asuka, he just wanted to know more about what the situation was like right now.

"System?"

"Lord God?"

"Mission?"

He tried to call, but there was nothing, he didn't have a board, he didn't have a task, and he didn't have a starter pack.

"What nerves are you having?" Asuka frowned and looked at the boy across the mirror.

It's just a little boy who hasn't developed at all, childish, with a Western face, and the eyes are pretty good-looking, like blue gems, and his appearance is okay.

But he was too young to be interested in communicating with him.

"I'm talking about you, your name is Ian, isn't it?" Asuka looked unkind: "Please be quiet, since it's my dream, I should listen to my master!" ”

"I'm sorry." Ian gave up on the call system: "Asuka, I want to ask you a question, you... Do you know what the formula for gunpowder is?"

Ian wanted to confirm one thing, whether it was a dream or not.

If it were a dream, there was one thing that could never have been made up.

That is knowledge, and it is impossible for him to know what he does not know.

As a leukemia patient who grew up in a hospital room, his knowledge reserve was quite limited.

He didn't know all the familiar formulas of gunpowder, soap, etc., which was really embarrassing for the traverser.

He has not studied for a few years, and he is basically equal to half an illiterate.

"Of course I do, but why do I have to tell you?" Asuka snorted at Ian.

"Please." Ian was not polite at all, and sat down directly at Asuka Shishi: "I really need this recipe, I beg you to tell me." ”

"Cut..."Asuka smacked her lips: "Forget it, it's not a secret anyway." ”

"To make gunpowder, saltpeter, sulfur and charcoal, the best accurate mass ratio is, 0.7464, 0.1185, 0.1351, which even junior high school students have learned, well, but you don't look like you went to junior high school."

"About seventy and a half, one out of ten and five out of five?"

"Rather, the first humans tried to figure out the optimal ratio little by little, and it was not until the fifteenth century that the Europeans gradually determined the optimal ratio of gunpowder."

"That's... I would also like to ask, where should I get these three materials? It is in the case of the fifteenth century how people gathered raw materials. ”

"I said you're not annoying, why are there so many questions?"

"Please, Asuka-sensei, please teach me." Ian sat down again.

"That's why I hate children, it's really annoying."

Asuka pouted, but answered Ian's question anyway.

"Saltpeter is the soul of gunpowder, places like China and India, there is natural saltpeter in the soil, but Europe has no more, Europe is congenitally insufficient, there is no large area of nitrate resources, they collect nitrate from all corners of the people, the roots of the foot wall, the livestock pen, the public toilet...... In short, where the smell is stronger, the white nitrate is the most, after all, that thing is solidified nitrogen, and there is a lot of it in the feces. ”

"In other words, do you look for it in a toilet or something... What does it probably look like? ”

"White powder."

"Teacher, what about the brimstone? Is there anything special about charcoal? ”

"Don't call me teacher!" Asuka raised her face: "Sulfur is found in most minerals, natural sulfur, pyrite and marcasite, etc., as for charcoal, it is generally best to burn it with alder or European buckthorn and willow." ”

"Willows—" Ian nodded, jotting down the materials and proportions.

"I said you remember it so clearly, what do you want to do?" Asuka asked.

"As I said before, I'm actually a slave on a farm, and in a while, I may face a life-threatening crisis, so I want to make some gunpowder out, maybe it will work." Ian said.

As a slave, he could not leave the farm without permission, and the housekeeper was responsible for the procurement of supplies on the farm, and if he left, if he was discovered, he would probably be executed.

I think the reason why I bought a child like him to work on the farm is also to work confidentially, he was born very clean, has simple interpersonal relationships, and has been cultivated since childhood, which is very suitable for taking care of the illegitimate daughter of the Lacey family.

"Really..."

Asuka didn't bother to bother with these details, but maybe it was a whim, and she said a few more words.

In the past, when Europeans mixed powder, they had to add water and wine, make "flour" into "cakes", and then crush the cakes, and then use bronze or stone grinders to break them into the size of grains, and after sifting, they separated the gunpowder particles of various specifications, and they called that thing wheat gunpowder, which was made in that way and was much more stable. ”

"Thank you, I see." Ian thanked him.

They all felt something, everything around them turned into mist, the mirror faded away, and darkness slowly came.

"Goodbye! Nice to meet you! Asuka! Ian yelled into the darkness.

"Cut."

In an instant, Ian woke up from a dream and saw the sunlight shining through the cracks in the window.
