Chaos Furnace uses Khaenri'ah's technology, and so does the Trap system.
Missiles use Khaenri'ah's technology, and laser cannons use Khaenri'ah's designs as well.
The entire ship, except for the final machine and a few other components, was primarily based on Khaenri'ah's advancements.
Most of the designs were compiled from the materials given to Takumi by Zhongli.
In other words, most of it was Khaenri'ah's technology.
However, despite having the blueprints, current alchemists were unable to replicate components like the Chaos Furnace.
In other words, Takumi was the only one who could realize these key parts.
It didn't matter much. These features were only meant for battleships anyway.
It wasn't feasible to mass-produce warships, so only a limited number were needed.
If worse came to worst, he could always dismantle some of the Ruin Guards, extract their Chaos Furnaces, and repurpose them.
Problems always had solutions.
With the blueprints for various ships completed, Takumi immediately sealed them up.
Some of the core details would not be shared with just anyone.
He made backups and planned to send a few copies to Ningguang.
At the shipyard, each part would be built separately and then assembled in one place.
The shipyard was big enough for efficient assembly-line production.
Leaving his office, Takumi stepped outside and saw Keqing resting while sipping tea.
Takumi blinked in surprise.
"Keqing! You're actually taking a break? This is rare."
Hearing Takumi's words, Keqing was slightly taken aback.
"Have you finished reading all the books?"
She knew that Takumi had been buried in books during this time.
Since the books were given by the Geo Archon himself, she hadn't interrupted him.
She only reported important work matters to him at night.
"Yeah, I finished them all."
"Why are you resting here? Aren't you busy?"
Hearing Takumi's question, Keqing shrugged.
"There's not much that requires my direct involvement right now."
"So I actually have some free time."
"There are people monitoring the construction site."
"Departments are in place and handling things well."
"So for now, I'm free."
She really was free. Most tasks no longer required her direct input.
With teams from various departments in place, things were running smoothly on their own.
Even if Takumi and Keqing were absent, the work would still progress efficiently.
Hearing Keqing's explanation, Takumi nodded in understanding.
"I see."
"Then how about we go out for a walk? Do you want to go back to Liyue?"
Takumi planned to return and give Ningguang the ship designs.
He wanted her to focus more on the shipyard.
Before seeing the blueprints, she probably wouldn't take it seriously.
After all, Ningguang was the type of person who wouldn't act without seeing tangible benefits.
Hearing Takumi's suggestion, Keqing thought for a moment before agreeing.
"Alright, let's go."
"It's a good time to return."
After saying this, she stood up and started walking outside.
Seeing this, Takumi quickly followed.
As they reached the entrance, Keqing was about to head toward the vehicle when Takumi stopped her.
"Take this instead—it's faster."
Takumi pointed to a flying motorcycle parked nearby.
Keqing was momentarily stunned before nodding.
She knew this was one of Takumi's new inventions, but she had never used it before.
Takumi walked over, sat on the motorcycle, and patted the back seat.
"Hop on!"
Keqing hesitated for a moment before getting on.
"Hold on tight."
"I'm starting now."
With that, Takumi started the motorcycle and took off.
The sudden acceleration startled Keqing, making her instinctively grab onto Takumi.
Takumi smirked as he felt Keqing's grip tighten around him.
Riding a motorcycle with a girl—this was the dream.
Thinking this, Takumi activated flight mode.
The next moment, the motorcycle lifted into the air and shot forward at high speed.
Keqing's eyes widened in surprise.
The speed was incredible.
Flying was truly faster than running.
She couldn't help but wonder—should they build more of these flying vehicles?
Lost in thought, Keqing silently contemplated the possibilities.
Meanwhile, Takumi continued flying towards Liyue Harbor with Keqing.
This scene, however, did not go unnoticed.
Shenhe happened to witness them taking off in the flying machine.
Her brows furrowed slightly.
Especially when she saw the way Keqing was holding onto Takumi—it made her feel uneasy.
But then, Shenhe recalled something.
She remembered reading in a book that, as a noblewoman, one had to be magnanimous.
The book also mentioned that great men often attracted many women around them.
Like flowers attracting bees.
So, in moments like this, one must not be jealous.
Instead, they should be understanding.
That was how one could become a wise and respected woman.
Perhaps… this was one of those moments.
Yes, it must be.
Takumi, completely unaware of Shenhe's thoughts, continued answering Keqing's questions.
Keqing, after some thought, spoke up.
"Takumi, can you make your flying machine bigger?"
"Big enough to carry a large number of people?"
"If you can create that, it would be incredibly convenient."
Hearing this, Takumi was momentarily stunned before nodding.
"Yeah, it's possible."
"But it's not necessary."
"I want other alchemists to develop it on their own."
"Not everything has to come from me."
"I'll provide guidance, but I won't create everything myself."
"If I make everything, then what's the point of having alchemists?"
"They need to retain their ability to innovate."
"Innovation is the most important thing."
If Takumi personally designed everything, it would stifle creativity in others.
He had introduced cars and motorcycles.
If alchemists and mechanics couldn't think of making planes on their own, then they might as well retire and become farmers in Qingce Village.
Takumi never restricted research.
As long as it had value, it was worth pursuing.
That was the philosophy he had shared with the researchers.
In the future, he would even provide funding for their projects.
If they needed materials, they would submit requests, and procurement teams would handle the rest.
Takumi didn't want to dictate everything.
At first, it was fine, but long-term, it wouldn't be beneficial.
Hearing Takumi's reasoning, Keqing nodded in agreement.
That made sense.
Perhaps some alchemists and mechanics were already working on it.
Takumi's flying motorcycle wasn't a secret—they had seen it before.
Even when Takumi was busy reading, researchers had come over to study it.
They might have already started trying to build their own versions.
