"These precision parts require the use of a lot of metals, steel, iron, copper, and even gold and silver."

"If it's just a mechanical clock, it can be achieved."

"We just need to overcome technical difficulties, such as clockwork, screws, and springs. I'm afraid it won't be easy to achieve."

"Well, I'm very interested in what you said. So, let's start with the sundial."

(Zhao Li's)

"After making the sundial, everyone will have a clear sense of time."

"Okay, let's get started. With the omnipotent tool, we can make it soon."

"However, to fully cooperate with the sunny sky, we need the sky and his shadow!"

The sundial completely captivated Vivian.

Nishi Xiaochuan talked about the knowledge involved in the sundial, which also made Vivian thirsty for knowledge.

Heavenly stems and earthly branches, Zichou Yinmao, twelve hours, every second concept...knowledge...

Everything attracts him.

"How powerful is this ancient Eastern country?"

Nishi Xiaochuan looked at the engraved sundial dial and listened to his explanation.

Vivian couldn't help but be filled with longing.

Nishi Xiaochuan discovered the correct way to open his sister-in-law. It's very simple for her to work. Give her knowledge!

PS:

I saw someone in the comment area saying that the progress is fast, is it fast?As for the rise of writing, there are very few people who urge me to send flowers and big tickets.

So, continue to beg, beg to send a lot of flowers, vote, reward, remind updates, subscribe, beg, please protect me.

83 My sister-in-law is mighty and has a magic sundial (please subscribe)

It's not that Nishi Xiaochuan disliked his sister-in-law for eating free rice and not working.

After all, my sister-in-law called Xiao Chang'an to get a maid group from the vampire clan.

Nishi Xiaochuan felt that with his sister-in-law's incredible magical talent, it would be a waste to stay still.

Why are you a nerd? Be a doer!

Vivian stared at Nishi Xiaochuan's carved sundial seriously.

In fact, she has always been curious.

Let’s not talk about what kind of existence the ancient Eastern country is.

As far as this brother-in-law is concerned.

I understand, I can, there are too many.

Moreover, it is ridiculously strong.

Can you do something like carving?

Speaking of which, the statues in the shrine are all lifelike. They must be the gods of the ancient Eastern countries.

"Busy working?"

"Busy working."

"Give you."

Aunt-in-law Vivian directly handed Nishi Xiaochuan a glass of juice.

It's his favorite blueberry flavor.

Pour it yourself?

"thanks……"

Nishi Xiaochuan was a little flattered.

My sister-in-law pours the drinks herself. There can't be any subtle plot, the cold lady shouldn't be like this.

Sure enough, after Vivian gave him a drink.

Continue to look down at the clock design in his hand.

"Thank you, I asked you to hold it for me."

……

My time? ? ?

Nishi Xiaochuan's mouth was already glued to the mouth of the cup.

The drink is already in your mouth?

Do you want to play dirty, do you want to spit it back, will you be beaten to death?

If you don't get beaten to death, you will be sickened to death by yourself first!

Nishi Xiaochuan complained to himself and was confused for three seconds.

Without blushing and without a beating heart, he calmly held the cup in his hand: "I will treasure it for the rest of my life. Don't worry, no one will know."

The aunt's face was expressionless, as if she hadn't heard anything.

Calmly holding the clock design in his hand.

He stretched out his hand as steadily as an old dog and took back the cup.

"I want to ask you about this design drawing."

But she was already panicking inside.

What should I do if I take it back? Should I take it back? Should I not take it back?

Do I want to keep drinking?

Have you kissed indirectly?

ah, so shy...

But his face is still as steady as an old dog.

It's okay to kiss her, after all, it's indirect, and besides, it's my sister's property.

His face continued to look as steady as an old dog's.

Nishi Xiaochuan looked confused. As expected of her sister-in-law, she actually took it back and acted as if nothing had happened...

Want to take a sip, will there be an exchange of saliva?

Is it possible that my sister-in-law is the kind of ignorant girl who thinks that indirect kissing can lead to pregnancy?

Nishi Xiaochuan, who had been fascinated for a while, had a rare moment of drama.

Nishi Xiaochuan really has no idea about this kind of cold and calm lady, who is as steady as an old dog.

However, according to the majority of netizens in the past life, this kind of flower of the high mountains was generally boring, and the more boring it became, the more sexy it became.

"what happened?"

Nishi Xiaochuan came to his senses and quickly stepped forward.

Are you as steady as an old dog? I can too. If you don't mind, I'm not bad either.

"These precision mechanical parts are even more sophisticated than the skills of the master dwarf craftsmen. I have seen the design drawings of very powerful dwarf craftsmen."

"But I've never seen a blueprint like this."

"What kind of painting method is this? Why does it look real? It seems that these parts are clearly visible and really exist on the paper."

"Is this the painting method of your ancient Eastern country? How did you do it?"

"First of all, I want to thank our family for the paper."

"I would like to express my gratitude to Sister-in-law Vivian for the successful production of pencils."

“In the end, I have to thank math.”

"Is this also mathematical knowledge?"

Nishi Xiaochuan nodded, very good, my sister-in-law is really thirsty for knowledge.

"Do you know geometric shapes?"

Vivian shook her head.

"This is the geometry of mathematics."

"Everything has mathematical knowledge in it, even painting and design."

"The pictures in this design are called solid figures, which are applications of mathematical geometry."

"This three-dimensional figure is a three-dimensional figure surrounded by one or more faces that can exist in real life."

“A point moves to form a line, a line moves to form a surface, and a surface moves to form a body.”

"It looks lifelike. Some drawings are more intuitive after drawing three-dimensional figures."

Vivian was completely immersed in it.

Subconsciously, I took a sip of blueberry juice.

Then they naturally looked at each other.

At the same time, he turned his head and pretended that nothing happened.

"Continue to compile mathematical knowledge into books when you have time. There are too few basic mathematics documents now. I don't know many things. You and your country have opened my eyes."

"Thank you for the compliment, sister-in-law."

(ceae) "Actually, you can just call me Vivian. My sister-in-law is very strange."

"Besides, I'm very curious about this drawing method. I didn't expect you to ask me to get a pencil. I didn't expect it to have so many uses. In the ancient Eastern countries, even a pencil cannot be underestimated."
