I built the Black Tower City in Sumeru.

Chapter 6 Teacher Nasita, how about I make you a doll?

Nasita's eyes lit up like never before.

Her small mouth was slightly open, and her emerald green pupils reflected this bizarre and fragrant world of candy and delicacies.

Is this... how guests are entertained in another world?

That seems so exaggerated.

It's like cramming the entire harvest festival into a tiny dream!

Wow...that's really grand!

Even though it's a dream world, it still shows care and effort.

She carefully took two steps forward, stepped onto the biscuit-covered ground, looked down, then squatted down and curiously plucked something that looked like a blade of grass from beside her.

It was a green, long, strip-shaped apple-flavored gummy candy.

Nasita put it in her mouth and chewed it gently.

It has a sweet and sour taste, and the aroma of fresh grass.

Her eyes instantly narrowed into two adorable crescent moons.

It feels pretty good!

Nasita found it very interesting.

Nasida loves sweets.

But as a deity, one should always maintain a certain level of reserve in front of guests.

So she just sipped and tasted each one, only a tiny bit of each, like a judge appreciating food, or like someone who didn't like this one and would try the next.

Chen Bo found it amusing to watch her savor the food.

He remembered that in the game, Narcissus's favorite food was date and coconut honey, but unfortunately he had never eaten it and could not conjure it up in his dreams.

It seems I'll have to go to Sumeru City to try it tomorrow, so I can recreate it in my dream to entertain her next time.

After all, everything in a dream is based on one's own memories and feelings. Even if you create something out of thin air that you've never eaten before, it won't taste right.

"Naxida, is there anything you particularly like to eat?" Chen Bo asked casually.

"I love them all," Nasita replied immediately, her eyes sparkling, a few crumbs of apple gummy candy still clinging to the corner of her mouth. "They're sweet and sour, with a fruity aroma, and the sweetness is just right, not cloying at all."

"Really?" Chen Bo teased. "But you only ate a little bit of each kind. It doesn't seem like you really like them. You're not lying to me, are you?"

Nasita earnestly defended herself, saying, "I have observed many human mothers, and they all tell their children to behave themselves when visiting strangers' homes, and not to stare at their favorite foods for too long."

Chen Bo was taken aback, then burst into laughter.

Different worlds, same mother.

My own mother had said the same thing to me.

"Don't worry, we won't be strangers from now on," he said gently.

The delicious food eased the initial awkwardness, and Naxida relaxed a bit, beginning to curiously inquire about Chen Bo's background.

Chen Bo did not hide anything and frankly admitted: "I come from another world. I am just an ordinary scholar who came to Xumi to study due to some unexpected events."

He didn't go into too much detail, but the identity of "scholar" still helped to bridge the gap.

Then, Chen Bo shared his thoughts: "Nasita, my field of study is mechanical engineering, and I want to... create a humanoid mechanical device for you as your body."

Chen Bo had his own selfish motives, because he envied the traveler for having a travel companion like Paimon.

If, if I could create a body for Naxida and let her live in it, wouldn't I then have a travel companion?

Naxida paused for a moment after she finished speaking.

Nasita's small hand, holding the candy, froze in mid-air. Her emerald green pupils widened suddenly, reflecting Chen Bo's image.

Imprisoned in the Pure Goodness Palace for five hundred years, she could only perceive the world by peering into the dreams of others through the void.

As a deity of Sumeru, she can forcibly possess someone's body.

But "love" is the underlying logic of the Teyvat gods, and she would never do anything to harm the people of Sumeru.

Now, this scholar from another world is saying he wants to create a body for her...?

A body that belongs solely to her, allowing her to walk freely?

"...a body that can go out freely?" Nasita repeated.

"Yes," Chen Bo answered affirmatively.

Rescuing Nasita is not possible at present.

But giving her a physical exam shouldn't be that difficult, right?

Seeing the expectation in her eyes, Chen Bo knew that he had hit the nail on the head with Naxida.

Nasita blinked and said earnestly, "This is a gift I can't refuse. So, how should I repay you?"

"I lack a mentor," Chen Bo immediately stated his purpose, "a mentor who can teach me the Sumeru Mechanism Technique."

He didn't beat around the bush.

"My research focuses primarily on robot perception, especially touch," Chen Bo began, explaining his expertise: "Simply put, it's about enabling mechanisms to distinguish what they are touching."

"For example, a special material can change its internal resistance when subjected to pressure. We can detect these changes to determine what the mechanism is 'touching' and how much force is applied."

"In my world, this material is often used in an instrument called an 'electronic scale'."

"In addition, I also studied gear traditions, and I studied this knowledge for four years."

To help Nasita understand more intuitively, Chen Bo began to concentrate and try to visualize the knowledge in his mind.

hum!

The panel for the Imaginary Technology System lights up.

[System-assisted dream modeling has been activated]

The next second, a transmission gear set appeared in Chen Bo's palm.

Sun gear, planet gears, ring gear... every component is clearly visible, and the complex internal mechanical transmission structure has been perfectly reproduced.

Differential gears, worm gears, universal joints... all sorts of transmission structures that Chen Bo knew by heart in his previous life appeared one by one.

Naxida began to observe carefully.

Some of these structures are present in Mount Sumeru, while others are not.

Chen Bo dragged over a planetary gear set, pulled it with both hands, and the gear set opened up, revealing the internal gear structure clearly in front of Nasita.

"This is a 'planetary gear,' which can achieve an extremely high transmission ratio with a very small size and distribute power evenly..."

Chen Bo was simply introducing the knowledge he possessed.

Nasita is very powerful. Over the past five hundred years, she has learned a vast amount of knowledge through the void, including various mechanical and biological mechanisms.

She hadn't seen many of these gear structures before, only a small portion of which were different from what she'd seen before.

"I understand," Nasita blinked her eyes, looking very cute. "You're better at transmitting power, so what you should learn now is the structure of the power source."

Human beings' common energy sources mainly come from electrical energy and chemical energy.

One is an electromagnetic reaction, and the other is a combustion reaction.

Electric motors and internal combustion engines can convert two types of energy into mechanical energy, respectively.

Sumeru also exhibits electromagnetic and combustion reactions, and can be used to make internal combustion engines and electric motors.

However, Sumeru possesses a more efficient and unique energy source.

In the dreamlike candy world, Nasita explained the structure of the Sumeru energy system to Chen Bo in a way that even a child could understand.

"Look, this kind of 'elemental crystal' is one of the cornerstones of the Sumeru Mechanism Technique."

With a wave of her hand, Naxida summoned a crystal-clear green crystal that floated in front of Chen Bo.
