In the laboratory.
Shishou, who had just returned from the Land of Demons, was examining the communication egg under the light, studying it closely.
After fiddling with it for a while, he brought the communication egg to his face and saw the names of Mikoto, Natsu Hyuga, Kushina, and Rinmei Hyuga appear on it.
Through his research, Shishou discovered the pattern of how names appeared on the communication egg.
The names of people within a hundred kilometers would automatically appear on the front of the communication egg.
Shishou could also search for specific names on it.
For example:
Otsutsuki Kaguya!
This was the true use of the communication egg that Shishou had envisioned.
Kaguya wasn't killed; she was sealed on the moon.
If Shishou could contact the lonely, sealed Otsutsuki Kaguya on the moon, he might be able to start an interstellar relationship with the Rabbit Goddess...
If he could win her over, he would have a much better chance of handling the future invasion of the Otsutsuki clan.
Thinking of this, Shishou glanced happily at the communication egg in his hand.
Within a hundred kilometers, it could ignore all obstacles to establish contact with the target, truly worthy of a legendary egg.
However, due to the vast distance between the ninja world and the moon, Kaguya's name remained gray, indicating she was 'offline.'
"If I want to win over Otsutsuki Kaguya, I need to find a way to the moon first."
"Too bad the heterogenous space left by Otsutsuki Hamura is not easy to find."
"It would be great if someone from the moon could come here so I could track them back."
Looking at Kaguya's gray name, Shishou muttered regretfully.
He then placed the communication egg in a box, set up a protective barrier, and stored it in a storage scroll.
Since he didn't know if the communication egg was a one-time use item, Shishou decided not to use it until he could contact Kaguya.
Next, Shishou took out the Rebirth Egg, ready to study it.
Just then, Mikoto Uchiha, Kushina, and Rinmei Hyuga pushed open the laboratory door and walked in.
Shishou stopped examining the Rebirth Egg and looked at them.
"What's up?" he asked.
The three women exchanged glances.
Kushina flew up to Shishou and said, "Didn't you say you would help me increase my strength?"
Shishou chuckled, giving Kushina a playful squeeze as he held her. "If I help you now, you might fall asleep again."
"I wanted to give you time to catch up with everyone."
"But if you want, I can help you right now."
What's with the way he says 'if you want it now,' Kushina thought, feeling a bit flustered.
"We've caught up already. Help me now," she insisted, pouting slightly before flying up to kiss Shishou on the cheek.
It's the only way, she thought, blushing. This jerk only helps his women get stronger.
Seeing Kushina's bashful yet determined gesture, Shishou raised an eyebrow, surprised at her initiative.
He let Kushina stand in his palm and activated his Mangekyo Sharingan, the three tomoe spinning rapidly.
Both Mikoto and Rinmei watched curiously, eager to see how Shishou would enhance Kushina's abilities.
As Shishou's Mangekyo Sharingan activated, Kushina's tiny body began to grow rapidly.
Her height increased from the size of a palm to that of an arm's length. With her delicate features, she now resembled a cute Barbie doll.
Kushina's potential is remarkable, Shishou thought. If she were to return to her original size, her chakra would be many times greater than before!
Feeling his chakra deplete by about a third, Shishou was astonished. His current chakra reserve was nearly a thousand points.
"Amazing," Rinmei said, watching Kushina's rapid growth in awe and envy.
Mikoto glanced at Kushina's figure, then moved to wrap her in an outer garment. "Mikoto is the best," Kushina said, snuggling against her. "Not like this pervert, always staring."
Shishou chuckled. "I'll make you some new clothes," Mikoto said, amused by Kushina's doll-like appearance. Holding Kushina felt like she was holding her own daughter, which was a strange yet exciting feeling.
Rinmei, watching this, couldn't help but feel a twinge of jealousy.
"Mikoto, you're the best," Kushina said, nuzzling into her chest before falling asleep.
[Ding! Spirit Bug Kushina is entering an advanced state. Please place her in the insect breeding space or keep her within ten meters. Advancement time: 15 days.]
[Fifteen days with no interruptions or summons.]
Fifteen days? Shishou thought, raising an eyebrow. Usually, the advancement time for insects doubles, but not for Kushina. This made him rethink her uniqueness.
The more special Kushina was, the better for him, Shishou concluded.
Once Mikoto and Rinmei finished making clothes for Kushina and dressed her up like a Barbie doll, Shishou quickly placed her in the insect breeding space, feeling that Mikoto and Rinmei were becoming a bit too obsessed with dressing her up.
"Alright, let me take you back," Shishou said to Mikoto.
Mikoto had already undergone the augmentation with Hashirama's cells and now just needed to let her body adapt to awaken Hashirama's power.
Mikoto nodded, then looked at Rinmei. "I'll visit you next time," she said before hugging Shishou as they disappeared.
Rinmei watched them leave, biting her lip. The display of Mikoto's strength made her yearn even more to enhance her own abilities.
