"Good apprentice, I have an important task to explain to you as a teacher."

"Obey the teacher's orders!" Xin Lang rice was still in his mouth, and he knelt on the ground with a thud, and slurred.

Wei Gong was full of black lines, and hurriedly helped him up.

Seeing Xin Lang's white hair, he was a little unbearable.

Sometimes this apprentice is too serious about certain things, such as respecting the teacher, etiquette norms or something......

"In this way, I am going to open a branch for the teacher, can you help me choose the location, there are so many requirements for the teacher, all of which are written on it."

After speaking, Emiya handed him a piece of stationery.

"No problem, Master, don't worry."

Xin Lang opened the envelope and glanced at it,

"It's to prepare for the sewage, isn't it? If the swordsmith is built in a place where the river is fast, or next to the sea, then the leftover scrap from the casting can be directly discharged into it, without worrying about the pollution around it caused by hoarding. ”

"No, no." Wei Gong frowned, although what Xin Lang said was also a problem, but more importantly, it was easier to use flowing water power to build power stations in these places.

However, he also realized from Xin Lang's words that he should not only consider the demand for nature and ignore the problem of waste emissions, otherwise he will pay a double price in the future.

As a result, the sewage treatment plant had to be redesigned, which is estimated to be a big expense.

……

Two days later, Cui Xiaoxiao celebrated her fifth birthday, and also received a gift from the palace.

Emiya really has a conscience.,The last time I told him about my birthday at the enthronement ceremony of Sword Rin Sakura.,This soul faint actually remembers.。

When she unwrapped the outside and took out the [gift], the whole person was dumbfounded.

Xin Lang was also dumbfounded.

It was a strangely shaped cylindrical with a cylindrical upper edge, and a slightly larger closed circular platform at the bottom, about 30 centimeters high, with a rectangular black box attached to it.

"What is this?!" Cui Xiaoxiao's smile froze on her face, and her face became very ugly.

"Electron microscopy." Wei Gong smiled, "Isn't your electron microscope like this at that time?" You know, it took me a lot of time just to make the high-voltage laser beam emitter inside, and the display next to it, I was able to experiment with hundreds of materials to get it? It would be nice if you could tell me the principle of the microcontroller and the principle of the computer in the future, and I will definitely do better. ”

Wei Gong didn't notice Cui Xiaoxiao's increasingly gloomy expression, and the more he talked, the more he got hilarious.

Cui Xiaoxiao cut off his words and said coldly, "Why do I want this kind of thing?" ”

"You can do a lot of things, such as studying the structure of matter, studying biology, ......."

Xin Lang was dumbfounded when he listened to it, and he didn't understand what the master and the little aunt were talking about.

"I don't want it, who would like this kind of birthday present?" Cui Xiaoxiao's tone has fallen to the freezing point.

"Haven't you always liked physics?"

"Emiya, you're an idiot! Big stupid! Cui Xiaoxiao was very angry and jumped down from her chair.

This time, she didn't even have the mood to kick the palace, and walked straight back to her room.

And slammed the door hard.

This time, it was Emiya's turn to be puzzled, and the whole person was in a state of chaos.

Women are incomprehensible creatures.

Isn't it you who said you wanted an electron microscope before, and you who said your birthday?

If this thing had been given to Galileo or Leonardo da Vinci, I don't know what they would have been excited about.

Xin Lang coughed and asked tentatively, "Master, I think that the little aunt, after all, is a girl, and she should prefer beautiful and cute things." ”

"Hey, big apprentice, you don't understand......"

Wei Gong glanced at Xin Lang, thinking that with his existing knowledge, it was useless to explain to him.

She's not just an ordinary girl, she's an authority in physics, a scientist who is obsessed with the truth.

Xin Lang let out a sigh and said earnestly, "I'm afraid you don't understand, Master." ”

……

At night, Cui Xiaoxiao was so angry that she didn't even eat, she was stuffy in the room alone, she climbed on the pillow, buried her face in it, and then let out a soft murmur.

"The big fool of the guard."

When it was over, she shouted again, "Big fool." ”

It was at this moment that the window opened and closed with a sound.

Cui Xiaoxiao sat up suddenly, but did not find any figures in the room.

However, her eyes were immediately drawn to another thing hanging on the windowsill—

It was a beautiful knee-length tutu skirt with a long lace bow tied at the neckline, and an edelweiss hooded cape on the outside, and the skirt was rusted with beautiful patterns, like a mysterious spell, and like countless stars connecting the threads.

Miraculously, it is changing differently with the moonlight.

Wei Gong listened to the advice of the eldest apprentice and made this dress with the drawings designed by Xin Lang.

He hadn't yet discovered that his new apprentice still had the talent of a tailor, and sure enough, there was an old man in the family.

Although he didn't think it was of any use, according to his thoughts, how could Cui Xiaoxiao like such a childish and flashy thing, but he was a more serious person, in order to tell his apprentice that Master's words were always right, he still made such a skirt with a hooded cape.

The material is a liquid crystal material discovered by Wei Gong in recent research, which is greatly affected by environmental factors such as external magnetism, electricity, light, sound, heat and external forces. When these factors change, the order of liquid crystal molecules will change, which will cause the refractive index of various colors to change, so in Cui Xiaoxiao's view, the color of this dress changes at all times.

When the moonlight is bright, the clothes turn light blue, like the beautiful sea water;

The temperature is lower, and the clothes turn lilac, revealing a luxurious atmosphere;

At this time, this delicate little dress showed a beautiful rose red again.

The unpredictable brilliant colors make people feel intoxicated for a while.

Cui Xiaoxiao burst into tears and smiled, and reached out to take off her clothes.

"Death Guard Palace, count you as having a conscience."

Early the next morning, Cui Xiaoxiao wore clothes made by the Wei Palace and had breakfast with them with a smile.

Now in the sun, it is holy pure white, and Cui Xiaoxiao is like a white rose, very cute.

"Morning, little aunt." Xin Lang's face was wrinkled with a smile as he scooped a spoonful of soy milk from the pot and put it into Cui Xiaoxiao's bowl before handing her the sugar.

Cui Xiaoxiao took a sip of soy milk, only to feel that it was sweet from her mouth to her heart.

"Morning, Brother Emiya."

Sure enough, Emiya rolled his eyes wide, thinking to himself, women are really the most fickle creatures in the world.
