Enormous Gains and Return
When Vegapunk said he would stuff Kaguya Otsutsuki into Hancock's body, he wasn't just talking the talk.
The Otsutsuki Clan are not purely flesh and blood creatures, but rather energy-based life forms formed from a large accumulation of Chakra. Therefore, their life essence is closer to that of Tailed Beast.
It was because of the Tailed Beasts that a wild idea came to Vegapunk's mind—why not create a large Tsutsutsuki Jinchuriki?
In fact, in the later Boruto series, there were indeed Otsutsuki Jinchuriki. These were guys who used the Karma seal of the Otsutsuki clan to use the power of the Otsutsuki. Using the seal to use the power of Kaguya Otsutsuki was just his initial plan. His final idea was definitely to have Hancock directly absorb all of Kaguya Otsutsuki's power.
As for why he didn't absorb it himself? It's because Vegapunk knew very well that although his physical strength was already very high, due to age, training, and other factors, he was still far inferior to Hancock. In comparison, Hancock could completely seal or even absorb Kaguya Otsutsuki's power, while he was just a tiny bit lacking.
Furthermore, having absorbed Kaguya Otsutsuki's memories and knowledge, Vegapunk also gained some understanding of the Otsutsuki Clan's Karma. This kind of reincarnated power, in addition to requiring the person with the Karma to be qualified, also has the concept of compatibility—at least the most outwardly obvious thing, such as gender, must be consistent.
In other words, Hancock is undoubtedly better able to absorb Kaguya Otsutsuki's power.
As soon as he finished speaking, Vegapunk immediately took action. He formed hand Hand Seals, and Kaguya Otsutsuki was quickly transformed into an immense amount of Chakra. Then Vegapunk placed his hand on Hancock's lower abdomen.
Vegapunk was speechless, absolutely certain that Hancock had done it on purpose. Given the strength of this Pirate Empress, sealing Princess Kaguya Otsutsuki might have been a bit of a strain, but it certainly wouldn't have resulted in her looking like this.
Fortunately, the seal ended quickly. Vegapunk withdrew his hand and looked at Hancock: "How was it? How did it feel?"
Upon hearing the serious matter, Hancock's previously flushed face regained its composure. She clenched her fist and said, "My Chakra has increased significantly, at least several times over. However, much of my Chakra is still sealed. It will probably take quite some time before I can fully utilize it."
"That's good. Just get used to it first!" Vegapunk nodded. "Once you've fully adapted to the power of this Progenitor of Chakra, I should have figured out what the so-called Karma is!"
By then, Kaguya Otsutsuki's power could be completely handed over to Hancock. Even before that, Kaguya Otsutsuki herself could be used to plant trees.
Vegapunk eventually controlled Kaguya Otsutsuki to collect a lot of raw materials for the God Tree, even cutting down the God Tree buds. It's not impossible for him to recreate the God Tree.
Just then, Vegapunk suddenly felt the scenery outside blur. He steadied himself and saw that Hancock also had a strange look on her face, clearly having also sensed the strange change.
"Is this... Space-Time Rejection? Are we leaving?"
With this thought in mind, Vegapunk looked at the group of unconscious ninjas and immediately began his looting operation.
As the towering purple light gradually dissipated from the ruins of the Ancient Kingdom of Roran, three people standing on the Sealing Array were revealed.
Well, there were three people when they went, and there were still three people when they came back. However, one of the women was pregnant with another life, so it was truly an extraordinary harvest.
Vegapunk's mind raced for a moment, feeling that something about this statement seemed off, but after glancing at Hancock in front of him and feeling the terrifying pressure of her Chakra, he still revealed a smug smile.
Besides Kaguya who was sealed away, the majority of the God Tree was also placed in the Amenominaka Space, which was originally Princess Kaguya and can now be barely controlled by Hancock. It can be said to be an excellent research material.
Not to mention, Vegapunk also gained almost all the knowledge in the Ninja World, and after winning the battle, he also collected a lot of spoils: Kakashi's pair of Kamui Mangekyo, Sasuke Uchiha's Eternal Mangekyo and Rinnegan, and captured a lot of White Zetsu...
With so much knowledge, Vegapunk's research on Chakra could make a significant leap forward in a very short time. Moreover, the large amount of data he collected on time travel saved him time in developing his own technology for traveling between worlds.
"I feel so uncomfortable..." Sara, who had been AFK the whole time during her time-traveling journey, managed to stand up with difficulty. After returning to the familiar world, she felt that her physical strength and spirit had recovered a lot, especially the energy emanating from the dragon Dragon Vein beneath her feet, which had gradually calmed down, greatly accelerating her body's recovery speed.
A moment later, Sara was almost fully awake. "Is this what it feels like to travel through worlds? I remember when Naruto traveled through worlds, they didn't feel like this. Is it because of my abilities?"
"No, the reason you are exhausted is not because you traveled through worlds, but simply because you were controlled by Genjutsu as soon as you traveled through worlds."
Vegapunk muttered a speechless comment, and Sara shuddered. "Controlled by Genjutsu? Ugh... Could it be you? What did you do to me?"
"An ugly woman like you wouldn't even get a second glance from me unless you came up to me!"
Hancock, clutching her stomach, spoke coldly. Sara turned to look at Hancock and saw a large hole in her clothes near her lower abdomen, with some strange runes still visible. She immediately shrank back.
"Stop overthinking!" Vegapunk tapped Sara on the head, his face full of exasperation. "Go back and rest for a bit. The Dragon Vein have calmed down now, and we'll begin our research tomorrow!"
Although Rōran had become a ruin, not all the houses had collapsed. At least after some cleaning, there was enough room for three people to live in.
The next morning, Vegapunk and Hancock began clearing the ruins. Vegapunk planned to build a large Research Base here, so naturally he wouldn't leave the ruins of Rōran on it forever.
With the ability to Magnetic Field Manipulation Chakra and magnetic fields, the cleanup of the ruins and the construction of the new Laboratory were carried out quickly. In just three days, the new Laboratory was already established in Rōran.
