Nebula's brain recorded her personal data from using the Heavy Sword rifle before. After comparing it with her current usage, she found that her physical fitness had improved dramatically. She remembered that the potions Ethan made were supposed to be slow-acting.

"Your potions are quite special."

Nebula's significant physical improvement wasn't surprising at all, as the nanite components were equivalent to replacing more than half of her body. Naturally, her new body had much better physical capabilities.

If it were anyone else, their bodies would still be the original ones after using the potion, requiring gradual modification and improvement, so the effects would naturally be much slower.

"Your new body still retains some ordinary flesh and blood. This part still has room for improvement. If you continue to train, your physical fitness will improve further."

Nebula's potion didn't completely lock her potential, it just meant her potential for development was relatively less.

After testing the Heavy Sword rifle, Nebula went to a laboratory specifically designed for testing physical data. This time, all non-essential personnel were cleared out, leaving only Ethan and other internal staff.

Here, Nebula could test her physical data in more detail. Overall, she was very satisfied with her new body, except that while her arms could transform into energy weapons, they lacked the energy to serve as ammunition.

It wasn't that Nebula herself had no energy, any living organism contains energy. Moreover, half of Nebula's body was mechanical, and these mechanical parts also had additional energy sources supplying them.

The problem now was that if Nebula relied on her own bio-energy or the energy maintaining her mechanical structure to shoot, she would quickly drain her own energy.

"So you have a few options now. Implant a powerful enough energy source within yourself, or simply learn to master a certain type of energy. Or learn how to utilize the various energies freely available around you."

In most worlds, this kind of energy floats everywhere. For example, the various magnetic fields, radiation, and matter present throughout the universe are all forms of energy. If Nebula could utilize these energies, she could also solve this problem.

"Relatively speaking, I personally recommend you learn to master a certain type of energy, followed by implanting an energy source."

Nebula didn't hesitate for long at all, perhaps she had already made up her mind.

"I want it all!"

"Huh?"

"First, implant a small energy source. I will also work hard to learn the techniques for utilizing the surrounding energy and determine the type of energy best suited for me to learn and master."

Ethan nodded. Nebula really did want it all, she didn't want to miss out on any method she could think of.

"Then go for it!"

Nebula finished testing her new body and was very satisfied with the compensation Ethan provided, so she started to care about her job.

"Is your new spaceship ready?"

"The modifications are complete. I originally came here to gather you all back."

However, it now seemed that most people couldn't leave this world for the time being, so he would probably have to go back by himself first.

"Anyway, I don't have anything important to do here. I can go back with you."

Nebula found staying in this world quite boring. The technological level of the Earth Federation was nothing special to a warrior like her who had roamed the universe for countless years.

Furthermore, due to her race, she had to live a low-profile life here, mostly avoiding contact with people.

Even though the modifications were complete and she no longer had racial appearance issues, she didn't want to just stay here doing nothing.

"That's good too. Anyway, after I go back, I need to set up a teleportation room on the ship."

After the teleportation room was set up, these crew members could freely travel between the Artemis (Moon Goddess) and the Starship Troopers world. Considering there wasn't much going on in the main world and they would be drifting and exploring in the vast universe for a long time, having everyone busy in this world now could prevent them from getting too bored.

"That's good. I'll ask around to see who else is ready to go back."

Selene and Annette definitely couldn't leave, they had to continue managing Cherry Military Industries here, at least until it was running smoothly.

Ada also couldn't leave for now, but she was relatively free and could travel back and forth between the ship and this world, the type who could come and go as she pleased.

The few who had joined the army couldn't leave right now. After Ethan sent out inquiries, O'Connell and Jonathan said they wanted to stay here for a while longer.

Logan said he could only go back after finishing the matters at hand. He was currently on a mission with the Roughnecks. Even if he wanted to go back, he'd have to wait until the battle was over to apply for discharge.

Betty was currently a ship's pilot and also couldn't leave immediately, but she had indicated that she would deal with things here as quickly as possible and return to her own world. She was the most eager to go back among everyone.

Mordred and Galahad, however, were willing to go back to the ship. This was because they were relatively free and could come back anytime after returning. They could also travel back and forth like Ada.

"Oh right, what about Evelyn and Sherry?"

"They were at the rifle factory before, but they should be arriving soon."

Evelyn and Sherry were definitely going back to the ship. This world held no attraction for them, watching stars back on the ship was more interesting.

Imhotep and Anck-su-namun were still busy developing their cult. They had finally trained their first batch of loyal followers and definitely wouldn't leave at this time.

However, Imhotep still asked for Ethan's opinion. If Ethan needed him back, he would naturally bring Anck-su-namun and come before Ethan immediately.

Considering Imhotep would have nothing to do back on the ship, it was better to let him stay here and busy himself.

After asking around and confirming everyone's wishes, there was no need for Ethan to stay here any longer.

"Are you planning to leave directly?"

"I'll go back early and set up the passage so you can travel back and forth freely."

He had no interest in fighting bugs, he wasn't very interested in the male and female protagonists of this world either.

Even if he wanted to establish a marine corps on his ship in the future, the male protagonist Johnny was an excellent command talent, but if he didn't specifically intervene, Johnny might grow up to become a general. How could he recruit him then?

As for the female protagonist, she would also grow up to become a fleet commander. She probably wouldn't be recruitable to serve him until she was old and close to death.

So, recruiting talent wasn't something to consider for now, especially since the Artemis wasn't short on people at the moment.

When Evelyn and Sherry arrived, Ethan took the few people who were ready to go back and left directly. Mordred didn't leave this time, she hadn't had enough fun yet. Consequently, Galahad also didn't leave, he had to stay and continue watching over Mordred.

When Ethan returned to the mansion, Laura happened to be teaching Leah some basic life skills. Actually, it was mainly teaching Leah how to use the team's learning equipment. Once Leah knew how to use it, Laura prioritized recommending several types of knowledge for Leah to self-study, only helping Leah with some adaptation, such as having conversations with her.

When Ethan returned with a few people, Leah was stumbling through a conversation with Laura using the newly learned language of the main world.

Seeing Ethan return, Laura looked behind him in surprise.

"Why did only a few people come back?"

"They all have things to do and can't get away for now. They'll be staying in that world for a while longer."

After briefly explaining everyone's situation to Laura, she learned that that world had been designated as a new base for sustainable development by everyone. Ethan would establish a stable teleportation channel on the spaceship after returning this time, allowing everyone to travel back and forth freely.

"That's a shame, hearing about it makes me want to go see it."

Although bugs sounded unpleasant, she didn't necessarily have to go to an alien planet and fight them head-on. She just wanted to see what Earth in that world was like.

Leah, on the other hand, was completely confused. She didn't understand many of the things Ethan said, so she just sat obediently to the side.

"Who is this little girl?"

Compared to Nebula, who paid no attention to Leah's presence, and Sherry, who was still observing with some curiosity, Evelyn simply asked.

"My new disciple."

This time, even Nebula turned her head to look at Leah. She knew about Ethan's terrifying strength, and a child noticed by such an existence would definitely not be an ordinary little girl.

Looking at the still very young Leah, Nebula suddenly thought of herself and Gamora. They were also adopted by Thanos from a young age and kept by his side and taught for many years.

"I really want to see what this child's talent is like."

"You're also going to learn energy manipulation and control. I believe you'll soon know what her talent is like."

Although he hadn't officially started teaching anything yet, Ethan was confident in Leah's talent. Whether it was her comprehension, personality, or bloodline, Leah had virtually no weaknesses in terms of talent.

Even without considering the Diablo bloodline, the remaining so-called ordinary human bloodline, given the special nature of humans in the Diablo world, Leah's bloodline was nowhere near ordinary.

Over the next few days, the returning individuals rested and adjusted briefly. Laura took some time to spar with Nebula again. Although it was just simple close combat, both were surprised by each other's improvements.

Evelyn and Sherry continued teaching Leah some basic knowledge, and Sherry also began teaching some introductory magic lessons.

Ethan then notified Bruce Banner and Maria Hill. After the two arrived with their luggage, Ethan took the few individuals who had changed into new gear and left the Marvel Universe, returning to his main world.

He released the Artemis on a desolate asteroid covered only in rocks. After being busy for so many years, he was finally officially setting off towards the sea of stars.
