Yanfei didn't think too much about it.
If it didn't work out now, they could discuss it later.
Just as she was about to bid farewell to Takumi, he suddenly said:
"Oh, right, Yanfei."
"Two guests from Mondstadt are about to arrive."
"One of them is Eula."
"She's a friend of yours, isn't she?"
Hearing this, Yanfei turned her head, a question mark practically forming above her head.
"What?"
"Eula is coming over?"
"Why didn't she tell me?"
Takumi's sudden words confused her.
Eula had never mentioned anything about visiting.
Why so suddenly?
Yanfei was shocked.
She quickly pulled out her phone and started typing a message to Eula.
Seeing this, Takumi couldn't help but smile and said:
"Maybe she wants to surprise you."
Upon hearing this, Yanfei hesitated, then quickly deleted the message she was about to send.
"That makes sense."
"If that's the case, I won't ask her about it."
"Alright\~\~!"
"I'll be off then."
"I'll go find Xiangling and ask her to help prepare."
"When Eula arrives, I'll treat her well."
With that, Yanfei hurried out.
That had to be it.
Otherwise, Eula would have mentioned it.
Thinking about it, Yanfei smiled to herself.
If Eula wanted to surprise her, then she would prepare a surprise in return.
She would definitely catch Eula off guard.
Well then, she'd have Xiangling prepare some of Eula's favorite dishes.
Gather the ingredients first.
When Eula arrived, she'd give her a proper welcome.
Thinking about this, Yanfei ran off.
Takumi shook his head, chuckling.
It wouldn't be long before the two arrived.
Takumi picked up his phone and tapped on Ei avatar.
He sent her a direct message.
Takumi:
[Are you there?]
[Send me a nice picture!]
[/funny.]
Ei:
[I'm here!]
[Here's a picture.]
To be honest, chatting with someone as gullible as Ei, Takumi felt he could get away with almost anything.
Hmm.
Sister Ei was just too easy to fool.
If Inazuma continued to follow a leader like her, wouldn't they be doomed?
Takumi continued chatting with Lumine while thinking to himself.
Soon, he received another message from Ei.
Apparently, she was working on Inazuma's power grid.
Her retainers had suggested the idea, so she had been studying electricity every day.
The basic wiring was simple enough for her to grasp immediately.
She had even learned some principles from Liyue's electrical engineers.
At the moment, Ei was working on a device that could automatically capture Electro energy.
Since Inazuma was abundant in Electro energy, simply harvesting it from the atmosphere could provide power for a long time.
Reading about her progress, Takumi was impressed.
As expected of Teyvat's most dedicated shut-in.
Her technological advancements were quite impressive.
Thinking about this, Takumi suddenly recalled Raiden Shogun's puppet technology.
Would it be possible to develop prosthetics like a certain bishop's?
Hmm\~!
A means of extending one's lifespan?
Ei probably didn't need it.
Right now, she technically didn't have a physical body anymore.
She had already turned herself into the Raiden Shogun puppet.
If that was the case, couldn't he build a new body for Ei?
And when the time came for a proper revival, maybe even create another?
A triple success.
After pondering for a while, Takumi decided to send another message to Lumine.
It wouldn't hurt to drop some hints.
Takumi:
[Actually, my ability awakening is tied to technology.]
[If Teyvat's technology advances, my power will continue to grow.]
[In Liyue, I've created many things, and thanks to the Heart of God, I've awakened several abilities.]
[Do you have any data on the puppet technology used to create Raiden Shogun?]
[Could you send me a copy?]
[If I study it, my power might evolve further.]
Ei, who had been lying around playing on her phone in Tenshukaku, immediately sat up upon seeing Takumi's message.
She carefully reread it.
She was surprised.
She recalled what Yae Miko had mentioned before.
Liyue had become highly advanced.
And a lot of it was because of Takumi.
Even the phone she was using now was his creation.
"So this is how his power works?"
"He needs alchemy?"
Thinking about this, Lumine quickly made a decision.
Ei:
[Alright!]
[Give me a moment, there's a lot of information.]
[I'll take some pictures for you.]
Takumi smirked when he saw Ei response.
Puppet technology? That was a done deal.
And he wasn't even lying.
After all, the more advanced civilization became, the stronger his abilities would be.
Takumi was almost certain of this now.
Though he still wasn't sure which core would activate next.
But he hoped it would be the Herrscher of Death's power.
As Takumi eagerly waited, Lumine began sending him pictures.
Khaenri'ah's puppet technology.
Along with her own research.
Instructions on how to transform a body into a puppet.
And the method for imbuing a puppet with a consciousness.
Good grief.
This was basically Teyvat's programming manual.
Would it be possible to hand Ei a computer and trick her into coding?
Takumi browsed through the materials, muttering to himself.
Lumine had sent quite a few images.
But with Takumi's exceptional memory, he processed all of them easily.
This made him appreciate Khaenri'ah's alchemy even more.
Whether it was from Zhongli or Ei, all this information was incredibly valuable to him.
Especially the puppet transformation techniques.
They even detailed various materials used in construction.
Even though Ei had turned herself into a puppet, this was still a human-developed technology.
These artificial bodies were indistinguishable from real people.
Thinking about Raiden Shogun's lightning-based attacks.
Both Zhongli and Ei had these kinds of documents…
So what about Aether?
Takumi suddenly recalled what Lumine had told him before.
Her brother had come looking for her.
So, should he try and get some of Khaenri'ah's technology from Aether?
For a moment, Takumi was deep in thought.
But how would he even enter the Abyss?
Without Abyssal power, it would be difficult to open a portal.
Or… if he obtained the Herrscher of the Void's power, could he easily locate Aether?
While Takumi was thinking about this, Ei continued sending files.
He stopped overthinking and focused on analyzing the data.
But he didn't forget to send one last message to Ei.
Takumi:
[Thanks\~!]
[Once I finish reviewing this, I'll contact you again.]
[With this technology, I might be able to create a body for your sister first.]
Seeing Takumi's message, a flash of surprise crossed Ei face.
