Because slimes themselves don't need to eat to sustain their lives, they can absorb free energy from nature to maintain themselves, and solar energy and other light energy also count as their food.
Of course, aside from free energy, they can also eat to accelerate their growth. What Takeru is curious about by letting an attribute-less slime live here is whether they will evolve faster.
After all, the magic concentration inside is more than three times that of the island where Takeru and the others currently reside, and more than ten times that of the city. Moreover, the portable space seems to have special rules.
After finishing everything, Takeru returned to the outside. He didn't need to worry about Midori and the other two, because Takeru had already taught them the teleportation ability, allowing them to freely enter and exit Takeru's portable space.
After coming out, looking at the slimes still slowly devouring, Takeru didn't pay them much attention.
"Master," Seeing Takeru suddenly appear in the room, Ai rubbed her eyes and called out softly to Takeru.
"Morning, Ai!" Looking at Ai who had woken up, Takeru greeted her with a smile.
"Huh, Midori and the others aren't here, and there are so many more slimes!" Looking around, Ai spoke puzzledly.
"As for Midori and the others, I asked them to help me with something. As for the slimes, they can split," Takeru explained softly upon hearing her words.
Hearing Takeru's words, Ai nodded thoughtfully, didn't investigate further, and went directly to the bathroom to wash up. She still helped make breakfast every day.
After glancing at Ai, Takeru walked out of the room. Ram was already waiting early for Takeru by the door, while Rem was preparing breakfast.
"Master!" Seeing Takeru, Ram showed a happy smile.
"Morning, Ram," Looking at Ram, Takeru smiled and patted her head.
Then, with Ram, Takeru arrived at the living room, where he happened to see Mai who had just woken up. He greeted her with a smile.
Going outside, he saw Yukino and the others doing morning exercises.
"Morning, Yukino, Sylphin, Umaru, and Taihei!" Looking at the four, Takeru greeted them with a smile.
"Morning, Takeru!" Seeing Takeru come out, Sylphin waved at Takeru energetically.
"Morning, Takeru. Can you come here for a moment?" Seeing Takeru come out, Yukino stopped her morning exercises and came directly to Takeru's side, speaking to him.
"Sure," Hearing her words, Takeru nodded with a smile and followed her to a slightly more distant open area.
Then, Yukino directly took out ten special fish and the corpses of two wyverns and placed them in front of Takeru.
"What are these?" Looking at the items she handed over, Takeru was surprised.
"Takeru, you should be collecting materials from these monsters, right? These things are useless to me. I hope they can help you," Hearing Takeru's words, Yukino brushed her long hair aside and spoke softly.
"Uh, thank you!" Hearing her words, Takeru was surprised, then looked at the wyvern corpses. Takeru had one of the two wyvern corpses, which was Jesby's mount. The other was actually Lagee's, but because Takeru killed Lagee too quickly, he never had a chance to call his mount.
Subsequently, Takeru looked at the other ten fresh saury fish...
[Boneless Mackerel Pike: Like a mollusk, a saury with no bones at all. Its flesh is better than ordinary saury. When grilled over charcoal, the whole thing from head to tail is edible.]
"Huh, how did you get these?" Looking at the saury's description, Takeru was stunned.
"I got a cross-world draw chance from the mission reward chest and drew them. Unfortunately, they were still alive when they came out, but when I put them in the item bar, they lost their lives. Takeru, do you recognize them?" Hearing Takeru's question, Yukino didn't hide anything and spoke directly.
"I'm not sure, but they seem to be a special type of delicacy. They're quite useful to me. Thank you. I'll transfer some points to you," Hearing her words, Takeru said directly.
"Wait, Takeru. I'm giving you these not because I want your points, but because I want to thank you. After all, whether it's this training or the delicious food you usually share with us, those things aren't things money can buy, right?"
"If you're willing to consider me a friend, then don't mention this again," Hearing Takeru's words, Yukino said somewhat angrily.
"I understand, thank you!" Hearing her say that, Takeru was surprised, then directly stored the giant dragon corpses and the Boneless Mackerel Pike.
"You're welcome. I'm glad I can help you a little," Hearing Takeru's words, Yukino's smile returned.
"By the way, you said they were alive before?" Hearing her words, Takeru asked quickly.
"Yes, they were alive when drawn. But for ease of carrying, I put them in my item bar. When I took them out again, they were like this," Hearing Takeru's words, Yukino said directly.
"If that's the case, maybe they can be revived," thinking this, Takeru directly used the Time Rewind skill. Then, under Yukino's surprised gaze, the ten Boneless Mackerel Pike regained their vitality, wriggling in the air!
This confirmed Takeru's hypothesis: Time completely does not exist in the item bar. Otherwise, no matter how strong Takeru's ability was, he couldn't revive fish that had been dead for ten hours.
Currently, the maximum time Takeru could rewind for an item or creature ranged from ten minutes to over an hour, depending on the item.
"Yukino, I'm going to raise them first. Wait here for a moment," Saying this, Takeru quickly entered his portable space.
Then, taking the Boneless Mackerel Pike, he went to the sea area and released four into it. For the other six, he created a special breeding area and placed them there.
Although these fish were unique, Takeru found they didn't have much power. Releasing them in the ocean might lead to misfortune.
After doing this quickly, Takeru returned to Midori and the others.
"Onii-chan, you're back!" Seeing Takeru return, Midori smiled and greeted him.
Although only about ten minutes had passed outside for Takeru, over three hours had passed inside. When Takeru wasn't inside, the flow rate between inside and outside was 20:1.
Arriving here, Takeru noticed that three slimes had already evolved. They were the ones catalyzed by Midori, Aoko, and Kurenai.
Compared to the slimes devouring on their own, the trio's feeding efficiency seemed higher.
The slimes fed by the three also had some color differences. They had a different hue matching their caretaker, like the one fed by Kurenai had a touch of red, Midori's was green, and Aoko's was blue.
[Catalyst Slime: A slime catalyzed by special energy. All attributes enhanced. Contains a large amount of magic power internally. Can convert magic power into most types of energy suitable for plant needs, accelerating plant growth without side effects during the growth acceleration process.]
Looking at the three slimes, although their colors were slightly different, they were the same species. Takeru showed a delighted smile. With them, much of the catalysis work could be handed over to them.
"Midori, come here for a moment," Looking at Midori's trio who were still harvesting Paradise Rice, Takeru called them over to fly to him.
"What's wrong, Onii-chan?" Hearing Takeru's words, the three asked curiously.
"After these three slimes evolved, did you have them help?" Looking at the three, Takeru asked curiously.
"Help? What can these little ones do?" Hearing Takeru's words, Kurenai circled the slimes and spoke puzzledly.
"They all possess part of your abilities. That means through special energy transmission, they can accelerate plant growth without side effects," Hearing her words, Takeru explained directly.
"Eh, really!" Hearing Takeru's words, Aoko said in surprise.
"Yes, let them help from now on. Then tell me about their abilities later," Looking at Aoko's surprised expression, Takeru said directly.
"I understand!" Hearing Takeru's words, the three nodded.
After that, Takeru looked at the other slimes still working hard to devour, then disappeared directly from the spot.
