Compared to that, the serum was insignificant.
Takumi quickly packed everything and sent it off.
Takumi:
[Himeko's exclusive red packet.]
[Everything's inside. I'll leave the rest to you, Himeko-neesan!]
Himeko:
[Got it~! Sweet talker.]
[Then let me share what I know with you too.]
Himeko was completely disarmed by how affectionately Takumi kept calling her "neesan."
Without delay, she packed up the knowledge she had and sent it straight to Takumi. Not via the store, but directly through a red packet.
Seeing Himeko's gift, Takumi's eyes lit up as he accepted it.
A torrent of advanced knowledge surged into his mind. As he processed it, his expression grew brighter.
Takumi:
[Thanks, Himeko-neesan~! I'm going to study this right away.]
With that, Takumi logged off. Himeko didn't mindshe smiled and started organizing what Takumi had sent her.
Superpower serum, magical tomes those could wait.
First, she'd sort through the bundle of items Takumi gave her to prepare for the exchange with Herta.
Everyone else watched this back-and-forth with mixed feelings.
Takumi's "neesan" act was too effective.
He'd completely abandoned his dignity.
...
Himeko's knowledge was remarkably comprehensive: physics, electronics, aerospace propulsion
She even included specs for her orbital satellite cannon.
As Takumi absorbed the information, his eyes sparkled with insight.
He now had a clear picture of Honkai: Star Rail's tech level.
Impressive.
Especially in interstellar capabilities.
For a moment, Takumi felt like his own power had taken a huge leap forward.
If he had to, he could probably destroy the entire world now.
Though still at the "planet-busting" level, it was a serious step up.
Planet? Star?
At this point, it was all "planet-buster class" anyway.
The next step would be "galaxy-buster class."
That was still a long way off.
Shaking his head, Takumi stopped thinking about it and vanished from his villa by opening an Imaginary Space Gate.
Moments later, he reappeared in orbit, standing above Earth.
He looked down at the functional satellites still circling the planet.
His cross-shaped pupils gleamed.
He activated his Authority.
Gates opened one by one in imaginary space, absorbing all the orbital debris and leaving only the useful satellites.
Then he invoked the power of the Herrscher of ReasonHimeko's specialtyand began constructing orbital satellite cannons.
Just like her ultimate move.
Even if he didn't need them now, they'd be useful someday.
He also modified a few communication satellites.
After all, the internet was essential.
Once finished, Takumi returned to the surface.
Now, several orbital cannons floated in space above Earth.
Each shot could easily obliterate a city.
Total annihilation.
Based on what Himeko shared, she was incredibly powerful.
If she had access to her tech, she could casually operate at planet-buster level.
But in another world, her power would likely drop to just city-destroying.
Her technology wouldn't carry over, and even the power of Fate might not function in other worlds.
Though the group chat might help with that.
Still, Takumi wanted Himeko to test it eventually.
Feeling great about his progress, Takumi grinned.
He'd already surpassed the old tech he made.
He had advanced several generations in one go.
Chuckling, he shrugged it off.
It was fine. Let others take over the upgrades next time.
For now, things were going smoothly.
Satisfied, Takumi teleported back to his villa.
He grabbed a bottle of carbonated soda imported from Sagiri's world and collapsed onto the sofa.
The only working internet was the group chat now.
So, he decided to scroll through it.
Either that or nap.
He tapped into the group and did his daily check-in.
Then he started idly chatting.
Most people were busy with their own affairs.
Only Sagiri, the eternal shut-in, was online.
Takumi struck up a conversation with her.
The others replied now and then but quickly returned to their tasks.
Zhongli was still watching an opera, not yet retired.
The Rite of Descension was coming up soon.
Would he retire this time like in the game?
Takumi was curious.
As he chatted with Sagiri, a new message popped up.
Bronya:
[Your computer has finished downloading everything. Returning it now.]
She sent a red packet.
Takumi immediately claimed it and began reading through its contents.
Bronya's world was more advanced than Chika's or Sagiri's.
It looked like they were on the verge of achieving nuclear fusion.
But after skimming through it, Takumi quickly lost interest.
Takumi:
[Done! Honkai's still better.]
Bronya:
[(???)]
[Sorry, I guess my world is just a normal one.]
She was speechless.
She knew Takumi had just received a flood of tech from Himeko's world.
Now her data felt outdated.
Takumi:
[Still, thanks. That'll be all for now. Keep the laptop.]
He sent it back.
The AI laptop still had uses for her.
Bronya accepted it with a shrug.
Free stuff is free stuff.
Now she was curious.
What kind of tech did Himeko actually give Takumi?
Bronya:
[What kind of technology did Professor Himeko share with you? Spill it.]
Chapter 17: Have You Heard of the Orbital Railgun?
When Bronya asked her question, Takumi couldn't help but chuckle.
Without hiding anything, he began explaining in the chat group, eyes gleaming with excitement.
Takumi: [Have you heard of orbital railguns?]
Bronya: [!!!!] [What the? That's from sci-fi novels!]
Takumi: [Exactly~!] [The data Himeko gave me even includes orbital railguns and spacecraft schematics.]
Himeko: [It's just some tech I've come across. If it helps you, I'm glad~!]
At the time, Himeko was still organizing the computer Takumi had sent her. Seeing what he was saying in the group, she chuckled lightly.
She had only shared what she already understood. In her world, she wasn't even among the top-tier scientists. But if it could help Takumi, that was enough.
Bronya: [This is absurd!! That ability of yours is too enviable!]
She truly was jealous now.
Takumi's abilitygrowing stronger just by absorbing knowledgewas incredible.
Takumi: [When it comes to tech, unless it's beyond imagination, most things are no longer that useful to me.] [My power may be star-busting level, but even that depends on the star, right?] [Unless it's interstellar-tier technology, it won't really help anymore.] [What I need now are things like magic from other worlds to expand my knowledge base.]
He already had access to Honkai-tier science. Now, it was time to collect knowledge on magic.
He wanted to master both science and magic. And even mysticism, if it came up.
Takumi welcomed all knowledge.
Himeko: [If you were in our world, you'd probably walk the Path of Erudition.]
His thirst for knowledge impressed even her.
Takumi: [I'll pass. Choosing a Path is basically shackling yourself.] [I don't want that.]
He didn't want to be bound to one fate. Paths were merely the chains of destiny.
Himeko chuckled.
In her world, if you couldn't leave, maybe there would be no other option.
Takumi: [@akeno, @Zhongli, could I trouble you both to collect magic, alchemy, and the like?] [Whether by points or knowledge exchange, I'll trade for it.]
After chatting with Himeko, Takumi reached out to the other two.
Zhongli didn't hesitate.
Zhongli: [Already in progress.] [Aside from Liyue's immortal arts and mechanical techniques, I've also contacted Barbatos to collect alchemy materials.] [Furthermore, I plan to exchange with other gods for more. I'll send it all your way.]
Takumi was stunned.
Zhongli was going all out for him?
akeno: [My club is collecting some too.] [It'll take a bit of time.]
akeno was gathering resources too.
Now that she knew things could be listed in the shop, she was eager to make the most of it.
Points aside, it was smart to gather things while she could.
Takumi: [@akeno, thanks~!] [@Zhongli, old man, are you helping me this much because you need something in return?]
Takumi was getting suspicious.
Zhongli was gathering so much for himit couldn't be for nothing.
There's no such thing as free affection, especially across worlds.
Zhongli: [Indeed.] [I won't hide it.] [If Teyvat falls someday, I hope your world can take in my people.]
Reading Zhongli's message, Takumi understood immediately.
If anything ever happened to Teyvat, Zhongli hoped Liyue's people could migrate to Takumi's world.
That's why he was helping so earnestly.
Takumi: [If that's the case, you're welcome any time.] [Absolutely no conditions!]
Takumi welcomed them with open arms.
He'd be more than willing to move the entire Liyue over if needed.
Just imagining it made him excited.
If he refused, he'd be a fool.
So, without hesitation, he agreed.
Who knows when Teyvat might face disaster?
What mattered now was acquiring all of their resources.
And so, the two completed their secret deal.
No objections from either side.
Win-win for everyone involved.
With that settled, all they had to do was wait for the collections.
Takumi was in a good mood.
Just as he was about to say something, the group chat notified of new members.
[Simma Heavy Industries has joined the group.][Not an Assassin has joined the group.]
Seeing the two new names, Takumi paused.
"Not an Assassin?" Who the heck?
He blinked.
As for Simma Heavy Industries Simma? From that Chinese animation?
While Takumi was stunned, the others had already started welcoming them.
Chika Fujiwara: [Welcome, newcomers!!]
Sagiri: [Welcome to the group!!]
akeno: [Welcome, new friends.]
Zhongli: [Group Red Packet] [This is not a fake group.]
Worried people might think it was a hoax, Zhongli even clarified it.
A truly responsible group admin.
Takumi greeted the new members too.
Then, he immediately opened the system shop.
He was more curious about new listings.
Clicking inside, his eyes widened at the pinned items.
Several powerful features had appeared:
Skill Enhancement: 1000 points (10 for 2nd use)Purchased: 0 times
Teleport Talisman: 1000 points
Ultra Teleport Talisman: 100,000 points
Injury Recovery: 1000 points
Lottery Draw: 1000 points/attempt
Only five items, but each one worth the price.
Chapter 18: Girl, Let Me Visit Your World!!
There weren't many new items for sale, but each one was incredibly useful.
What Takumi had been waiting forthe tools for crossing into other worldshad finally appeared. Seeing these items, he became visibly excited. Now, traveling to other worlds had become incredibly easy.
And there was even a Large-Scale World Travel Talisman? Must be for transporting groups of people. Mass relocation was no longer a dream!
The mere thought thrilled Takumi. He couldn't wait to buy them and start recruiting people from other worlds.
However, with his current amount of points, he could only afford a few world-travel talismans and some body enhancements.
Right now, most of the group's points were in Takumi's hands. The others had even less.
Thinking this through, Takumi turned his attention back to the group chat.
By now, the two new members had already updated their profile names.
"TrueNotAnAssassin" had changed her name to "Megumi Kato"?
Seeing that name, Takumi's eyes lit up.
So it was Megumi!
As for "Sima Heavy Industries," that turned out to be someone he hadn't expected.
Miori Shiba?
The heiress from the world of the Cursed Children?
The moment he realized this, Takumi's eyes sparkled.
Miori Shiba: [I can hardly believe itother worlds really exist?]
[Are the items in the shop actually real?]
[Can the Superpower Awakening Potion truly awaken powers?]
Fujiwara Chika: [Of course it's real.]
[I used it and gained water manipulation abilities.]
Chika was already chatting with the heiress.
Seeing this, Takumi jumped into the conversation.
Takumi: [@Miori Shiba, are you there? Want to immigrate? If you come to my world, I'll give you a free Awakening Potion.]
[Come here and it's yours. No strings attached!]
He didn't beat around the bush. He went straight for the pitch.
Miori Shiba blinked in surprise. The Superpower Potion had been listed under Takumi's name, hadn't it?
But what did he mean by "immigrate"?
Miori Shiba: [Can you explain that in more detail? Immigrate?]
She still didn't fully grasp that one could live in a different world.
Nor did she understand what Takumi's world was like.
But his message intrigued her.
Seeing her interest, Takumi quickly clarified.
Takumi: [It means living in a different world.]
[In my world, I'm the only one left. You could bring people over to live here.]
[I'll provide housing and free Awakening Potions.]
[If you're curious, come and see for yourself.]
Miori Shiba raised an eyebrow.
This guy was the last human on his entire world?
Miori Shiba: [You're not some kind of dark lord who wiped everyone out, are you?]
Takumi: [Why would you think that?!]
[Come on, don't go labeling people as evil tyrants!!]
Ridiculous. Why did being the last human automatically make him the villain?
Miori Shiba: [Then what happened? Why are you alone in your world?]
Fujiwara Chika: [I know, I know!]
[He crossed into that world, but everyone there had already died.]
Miori Shiba: [....]
[Everyone... died???]
She was stunned.
What kind of world was that?
Takumi: [Pretty much.]
[But the world is safe now.]
[The only problem is, it's too empty.]
He sighed. That was the one major downside.
Just one human left in the whole world.
He couldn't even have a proper conversation.
If it weren't for the chat group, he would have gone crazy.
No internet, no one to talk to. Just imagining it was enough to drive someone mad.
After learning the details, Miori Shiba became even more curious about Takumi's world.
A whole world where humanity had been wiped out?
What kind of disaster had led to that?
Takumi: [Anyway, I call the shots now.]
[My power covers the entire worldit's completely safe.]
[If your current world becomes too dangerous, you can consider immigrating.]
