Afterwards, Jun An stayed in Froth for a while longer to help with the reconstruction, which was completed much faster than expected. Thanks to the Little Vitas diligently paying the price, Froth even expanded slightly.
Of course, after helping finish the rebuilding, Jun An didn't plan to continue his vacation. After all, from arriving at Salt Snow Holy City, then swimming around the Sea of Quanta for three to five days, Jun An had already been away from Earth for over twenty days. It was time to go back.
As for the Little Vitas, Jun An had already worked them over so thoroughly at yesterday's "silver party" that both their upper and lower mouths couldn't close, drooling together. They were currently in no condition to see him off. Kids were kids, after all, not as durable as Vita.
Of course, it wasn't entirely their fault. After Jun An fused with the Imaginary Divine Frame (likely referring to Nihilism/HoI fusion), his stamina had indeed increased dramatically. Even if he spent an entire day soaked inside them, his limbs wouldn't wrinkle.
Naturally, the reason Jun An needed to return wasn't because he was tired of screwing the same face, but because he really needed to pay his taxes back home sooner rather than later. After all, Theresa and Himeko had told him to save up the public grain from his days away, and they'd squeeze it all out of him at once when he got back. If he didn't return soon, Jun An feared his lower part would turn into a high-pressure water gun and still wouldn't be enough to pay off that debt. Just thinking about it felt like a steep price.
"Prometheus, Griseo, are you coming along?"
Prometheus had been brought here by Jun An, and Griseo was someone Jun An intended to bring back, so he specifically asked them. Of course, it depended on their own wishes.
"Mm, although I'm a bit reluctant to leave, I really should go back to Earth and see Sister Elysia, Mama Aponia, and the others." Big Griseo naturally had no objections. She had been adrift for fifty thousand years, after all. Even though she hadn't been awake for much of it, saying she didn't miss home would obviously be a lie.
"I will return as well." Prometheus replied. "Although I wish to avoid Misteln's discussions regarding mate selection rights, the industrial level here is not very high. It's difficult to meet the requirements for manufacturing the parts I need."
"Parts? What are you planning to build?" Jun An asked curiously.
Prometheus stated in her mechanical tone, "Due to the significant gains from this experience, I have finalized the upgrade plan and intend to begin the upgrade."
"...It's just that Froth's industrial development is somewhat lagging. It cannot produce materials like Soulium. Therefore, I must go to Earth to attempt sampling."
Jun An nodded, then directly used the Herrscher of the Void authority granted by the system reward to open a spatial gate to the Sea of Quanta. They then boarded one of Jun An's tamed Honkai Beast mounts together to leave. Since Froth was nearly a month's travel at light speed away from Earth in the intrinsic world, moving through the chaotic space of the Sea of Quanta was faster.
Griseo rarely had the chance to experience the Sea of Quanta, so she began looking around curiously, even feeling a burst of inspiration and wanting to start painting.
"You just mentioned upgrade parts? Which parts? Do you want me to have Bronya build one for you?"
Although Jun An had absorbed some abilities from that Judgement-class Honkai Beast that had struck Sa, the most useful were actually the abilities of the Judgement-class beast itself. The remaining authority from Sa, shattered by Kiana's three shots, was incomplete. Jun An couldn't even use it properly. It was like a program suddenly freezing halfway through execution. It would just crash. Even if Jun An tried using the authority scraped from Sa, it would ultimately just result in releasing Honkai energy from his palm, and nothing else.
Jun An couldn't help but suspect that Vita might have taken all the complete authority for herself, deliberately leaving only fragmented bits for him. After all, compared to Jun An, who was closer to the Imaginary Tree, Vita, as Sa's "body," was indeed more likely to obtain more advantageous abilities from Sa. For instance, she had taken seventy percent of the authority alone.
But that was seventy percent of what remained after Sa was shattered. While the volume was still frighteningly large, it was only about half a tier stronger than the Herrscher of Ice, around the level of the Herrscher of Sentience, not completely outrageous. Besides, Vita was smart. Even her chosen "revenge" was merely stepping on his foot to extract his haploid cells; she had no intention of making an enemy of Earth, so Jun An let her be.
Returning to the topic, since Jun An couldn't create things himself, he suggested Prometheus seek out Bronya, who looked similar to her.
"It is temporarily unnecessary." Prometheus shook her head. "I only lack some Soulium for modifying my body. The shaping process is best handled by myself." As one of the Previous Era's technological marvels, most of Prometheus's body was made of Soulium, so creating other accessories also required Soulium. If ordinary accessories couldn't conduct Honkai energy, then Prometheus, being driven by Honkai energy, might malfunction.
"Alright then. Is there anything else I can help with?" Jun An continued asking. "After all, I did forcibly drag you over here to repair the Ark's furnace. If there's anything you need help with, just say the word." Although there was some exaggeration involved, Jun An was at least an expert in Honkai-ology and should be able to offer some assistance. At the very least, Jun An could help acquire materials.
Prometheus thought for a moment. "There is indeed one matter that requires the Captain's help."
Jun An: "Tell me."
Prometheus produced something resembling a cup from somewhere. Looking inside the cup, Jun An was instantly stunned. The cup itself looked very expensive, possibly worth over a thousand.
"I made this over the past few days using materials from Froth. It's all-natural, pollution-free, and the texture was chosen to be as close to human as possible." Prometheus explained, "The internal shape is also designed based on the Little Vitas as the original model. I specifically added a humidification function, heating function, and a program simulating human peristalsis. I believe this can provide more stimulation and help the user accelerate the release of haploid cells."
"The only regret is that there is currently no one to help test it. Captain, could you help me try it out? And tell me your thoughts after using it?"
Jun An looked disgusted. "Is this sanitary? Besides, do I look like someone who uses cups?" The main reason was that Mei used to clean his room frequently when she was around, so Jun An had never liked using physical items, including manga. Compared to those things, using the data on his own cloud drive was better. Open it when needed, lock it when not. Plus, Jun An used the Hyperion's cloud drive, with security at the military secret level. Trying to find anything required getting past Ai-chan first.
"Rest assured. It has undergone Honkai energy sterilization. It is essentially impossible for any living virus to remain. Even if there were, it would be harmless to you." Prometheus aimed the cup's opening at Jun An and said, "Furthermore, I will not ask you to help for free. As compensation, you only need to stand during the process. The artificial part will be handled by me."
Jun An glanced at Griseo, who was captivated by the Sea of Quanta, and hesitated for two seconds. Having a top-tier artificial intelligence help him jerk off... Jun An thought it sounded a lot like a certain company's catgirl robot, but Prometheus was definitely more advanced than that.
"Deal!"
Jun An immediately took Prometheus to a hard-to-find spot on the giant beast beneath them. Judging by Griseo's enthusiastic expression, she probably wouldn't notice them for a while. Besides, this wasn't screwing Vita; Jun An would be the only one making noise. It should be fine.
Prometheus understood implicitly, kneeling before Jun An, unzipping his fly, pouring some water into the cup, sliding the cup on, and began her first service as an artificial intelligence.
Looking at Prometheus's appearance, Jun An couldn't help but feel pleased. After all, having a beautiful girl with the rare tag of [Robot Girl] helping him use a cup provided an unprecedented sense of novelty.
"Hah~" Jun An let out a long breath and asked curiously, "Speaking of which, why did you make this thing? Didn't Dr. MEI install one for you?"
"No." Prometheus lifted her skirt and took off her panties. Regrettably, it wasn't the body of a young girl, but rather a body and legs pieced together like a doll's, lacking the charging port Jun An had imagined. It was certainly very robotic.
"During the period when that world was about to end, Dr. MEI wouldn't do anything superfluous." Prometheus gripped the cup again, shaking it at a steady frequency. "And the reason I am modifying my body is also to become closer to human." Even though the resistance was much, much greater than Prometheus had anticipated, the motion of her hands didn't stop.
"Furthermore, I suspect Misteln will soon exercise my mate selection rights. As an artificial intelligence, I also hope to provide quality service to my partner." Prometheus looked at Jun An and said, "Therefore, if new accessories are installed later, I hope you will continue to give me new feedback."
Feedback after installation? Wouldn't that mean he could actually screw her?
Although Jun An was well aware of the most likely candidate Misteln would choose, he still deliberately asked, "Giving me your first time just like this, aren't you afraid your future husband will have objections?" Even knowing the likely outcome, this added element of uncertainty gave Jun An the feeling of cuckolding someone else's wife before they even got married. It felt good.
Prometheus looked at the cup, which had once again become much harder to move, surprised that the Little Captain could achieve a second transformation. But she answered Jun An's question first.
"I am a robot, after all. If my new accessories can be completed, as long as you can afford the price, then every time can be the first time for me."
"But if we're talking about the recorded first time, then personally, I hope it's the Captain."
These words, like a confession, made Jun An stand up straighter. He had to admit, Prometheus hadn't slacked off observing his interactions with Vita; she knew how to use the cup correctly.
Prometheus looked at the milk overflowing from the cup because the water valve hadn't been turned off, and asked, "How was it? What are your thoughts?"
"Your face is nice, and your technique is much better than Vita's." If possible, Jun An wanted to dirty her face next time, so he continued, "But I'll need to go again before I can give you more feedback."
Knowing the Captain's little thoughts, Prometheus didn't expose him, preparing to try again by hand. "Alright, then next time, please focus your energy on my product experience."
"Brother Jun An, and Prometheus—"
Griseo noticed Jun An's group, seemingly wanting to share what she had seen with him. But upon seeing the cup overflowing with milk in Prometheus's hands, her expression instantly shifted from joy to confusion and shock.
"What are you two doing?"
