Just as Prometheus had said, three minutes later, Shinonono Tabane appeared in front of Velvi.
Velvi put down her work and turned her gaze toward her.
"Hello! I've already heard from Prometheus. From now on, you'll be my assistant. But before that, I need to test you. Although many things in our worlds differ, they are fundamentally interconnected."
"Here is a set of data. You have one day to study it. Tomorrow, I want you to replicate what's inside. If you need anything, just ask Prometheus to prepare it. My lab is also open to you."
Velvi didn't beat around the bush and arranged a straightforward entry exam. The task was simple—recreate something from the data provided.
Tabane, newly arrived in this world, was momentarily stunned. A screen popped up in front of her, displaying a document released by Prometheus.
As she examined it, her eyes lit up.
"Alright!" she responded without hesitation.
After understanding who Velvi was, she didn't dare show any arrogance. Being an assistant? No big deal. Once she fully understood this world, she was confident she could hold her own.
This world's technology was just too advanced. People were already traveling in space. With the data in hand, Tabane left to dive into research and begin fabricating the object described—essentially, a weapon. Despite its simplicity in concept, it wasn't easy to create. She had to dig deep into the research.
If she had the ability, she could build it. If not, well... she wasn't going to be kept around.
After sending Tabane off, Velvi returned to studying the trove of data Takumi had brought back.
The GN Solar Furnace especially piqued her interest. Although perpetual motion engines existed, they weren't suitable for large machines or external trade.
While many of Takumi's technologies had been disseminated to other worlds, some were still too advanced. People couldn't understand them even if handed over directly. So alternatives had to be explored.
Other worlds were already considered to be under Takumi's control. It was only a matter of time before more technology was shared.
Now, with such data in hand, Velvi wasn't going to let the opportunity go to waste.
...
More newcomers had arrived in Takumi's world. But unlike before, no one paid much attention anymore. When only a few lived here, newcomers were a novelty. Now, arrivals were a daily routine.
For example, over in Liyue, new arrivals were showing up every day. Entire new city-states were being built. One such city, named Inazuma, was rising on an island not far from the coast.
Other cities, like Mondstadt, were also being constructed. These developments started while Takumi was traveling to other worlds. Zhongli had already sent people over to Ningguang. After consulting with Prometheus, they finalized city locations.
Just as Takumi returned home, he saw the updates.
He learned Teyvat had already begun moving. Surprised, he immediately sent a message in the group chat.
Takumi: @Zhongli, has Teyvat really started already? Did you already send people over?
Before Zhongli could reply, Ningguang—who had long been in the chat but seldom spoke—popped in.
Ningguang: Yes. Prometheus has divided up the map. Eight cities are being built. When Abyss Mages arrived here, they reverted to human form.
She laid out the situation simply.
Takumi rubbed his chin thoughtfully. It seemed those folks truly wanted to leave Teyvat.
Zhongli: They're all looking forward to it. I'm sending people every day. It's spreading across Teyvat. Celestia hasn't responded yet.
Zhongli finally chimed in. Despite these large movements, Celestia hadn't reacted at all. It looked like Celestia really was dying—no time to manage such matters. He just hoped that when Celestia eventually awakened, it wouldn't be too shocked. By then, Teyvat might be empty… or overrun by monsters.
Takumi: Emm... alright then. That's fast. Oh, old man, bring some local specialties. Send over some slimes too. Let's diversify the species in my world. Might even marry a slime to someone!
Takumi suddenly thought of something amusing. Since they were coming, why not bring a few souvenirs?
Zhongli went silent. This guy even wants slimes?
Zhongli: Doesn't your world already have slimes? Even if not, you could just get some from neighboring worlds. Those fused-in worlds surely have them. No need to overdo it.
Takumi: Not the same! Teyvat's slimes are cuter!!
Of course they weren't the same. Teyvat slimes had a prettier art style!
Nyarko: Slimes go better with monkey booze!
Just then, Nyarko bubbled up in the chat. But her message only earned a deadpan reaction from Takumi.
Takumi: Coincidence—I've got monkey booze in my world too.
Nyarko: (p≧w≦q) Can I come visit?
Takumi: Nope. You've got no points!!
Sagiri: Welcome! Save up your points and you can come later!!
Chika Fujiwara: I want to kill slimes and become a god!!
The group chat instantly turned chaotic again. Zhongli sighed as he watched the conversation derail.
He really couldn't keep up with the thinking of these younger folks.
Takumi didn't say much more. After watching them banter for a while, he closed the chat.
After thinking it over, Takumi vanished from where he stood.
When he reappeared, he had arrived at the Vampire Ninja Village.
His goal here was to find Sakura.
She now lived here with her sister, staying with the vampire ninjas and occasionally giving them a bit of guidance.
Takumi's reason for visiting Sakura was simple:
"Yingyingying~ Want to come meet your alternate-universe self with me~?"
He stood outside her door and called out cheerfully.
