Uchiha Yoichi explained, but he overlooked one point, which he couldn't tell Kaguya yet.
"To become husband and wife, to help each other..."
Otsutsuki Kaguya felt it was somewhat like a Guardian and the protected one, except that the Otsutsuki only had the Guardian help the protected one, whose life was supreme.
So Otsutsuki Kaguya looked at Uchiha Yoichi with her white pupils and asked, "Do you want to be my Guardian?"
"No, husband and wife!"
Uchiha Yoichi shook his head and said, "Your Otsutsuki relationships don't suit me, and since you're here, you must naturally follow the rules here. So, if I am to help you, the only way is to become husband and wife."
"What is it like to be husband and wife?"
Otsutsuki Kaguya lightly shook her head and asked, she didn't know how to interact between husband and wife, but Uchiha Yoichi's words made her moved; the person in front of her also had Chakra, not weak in strength, and was willing to help her, so becoming husband and wife wasn't bad.
Though she didn't know what husband and wife meant...
"No, Lady Divine!"
A shout suddenly came from outside the room, followed by the Land of Ancestors Emperor hurriedly pushing the door open and waving his hand, shouting loudly: "Lady Divine, no, you can't with someone of unknown background..."
Bang!
Uchiha Yoichi waved his hand, and then the Land of Ancestors Emperor was hit by a powerful impact, flying back more than a hundred meters, landing on the ground and directly turning into a pool of mush.
"You all get out too!"
Uchiha Yoichi waved his hand again, making the Emperor's guards fly more than twenty meters away, but he didn't take their lives, although lying in bed for over a hundred days was inevitable.
After displaying god-like power, the Emperor's wife and maids were so frightened their bodies trembled; however, Uchiha Yoichi left them as he still had use for them, so he didn't make a move.
"Go inside and take the two children next door to care for them, from now on, they are your responsibility."
After Uchiha Yoichi said this, the Land of Ancestors Emperor's wife didn't move, she was already scared to the point of being unable to act; but after a wave of Uchiha Yoichi's hand, she recovered.
"Yes, yes..."
She hurried inside, taking Otsutsuki Hagoromo and Otsutsuki Hamura out, even if she didn't know who the person in front of her was, she couldn't provoke him with such powerful abilities.
More than twenty people just now were the strongest samurai guards of the Land of Ancestors, but now all were lying on the ground unable to get up.
After driving people away, Uchiha Yoichi sat back in front of Otsutsuki Kaguya.
Otsutsuki Kaguya had no feelings about Uchiha Yoichi's actions earlier, those people were not on the same level as her, if not for her not knowing how to care for Hagoromo and Hamura, she wouldn't have bothered with them.
After sitting back, Uchiha Yoichi asked, "Continue talking about the earlier matter, what do you think?"
"I agree to become husband and wife, but what should we do after that?"
Of course, you...
This sentence wasn't said out loud, Uchiha Yoichi looked at the Strategy Guide, and with a righteous face, said to Kaguya, "You need to learn and observe on your own; there are many husbands and wives here, they become husbands and wives to combine their strength and cope with difficulties they can't handle alone, you can also use this method..."
"Is that so, quite similar to our clan."
Otsutsuki Kaguya nodded and said, with that, becoming husband and wife wasn't a bad thing, but after thinking, Kaguya asked, "If I go to observe, what about Hagoromo and Hamura..."
"They will be taken care of, you don't need to worry."
Uchiha Yoichi said, "I will also help you investigate your enemy's matters, since deciding to become husband and wife, I must exert some effort, but you also need to quickly observe and learn."
"Yes, I understand..."
After hearing Otsutsuki Kaguya's words, Uchiha Yoichi checked the affection on the Strategy Guide, at this time Kaguya's affection towards him had already increased to 55.
At a stage where she wouldn't attack him, and thinks of him as a good person.
Next just need to slowly strategize, if he couldn't handle someone as uninformed as Kaguya, Uchiha Yoichi might as well stop living.
But to not affect the future timeline...ultimately he might have to seal Kaguya's memory.
Unless he immediately ends interaction with Kaguya now, but returning after a millennium, the strategy progress would be stuck again, as the system states, the chance is only in this spacetime.
Then Uchiha Yoichi urged Kaguya to study and observe the interactions between spouses, as approaching night was when observation and learning would occur.
——————————
"Husband and wife, huh, sounds similar to Guardian, just mutual protection necessary..."
As night fell, Otsutsuki Kaguya walked outside alone, still recalling the conversations from the afternoon with Uchiha Yoichi.
Otsutsuki Isshiki wasn't dead, the Chakra divided between her two children seemed to be influenced by Otsutsuki Isshiki, so preparations must be made if she intends to reclaim it.
She must now become husband and wife with that person, together resist Isshiki and other Otsutsuki... in Kaguya's view, her greatest enemies were these people, so she needed Uchiha Yoichi to help her.
"To study relationships between spouses, at least study fifty to a hundred couples, then let's study fifty couples."
Kaguya thought of the task given by Uchiha Yoichi and decided to quickly observe, then after becoming spouses, they would handle fighting Otsutsuki Isshiki together.
"Regarding spouse, there should be quite a few here..."
Otsutsuki Kaguya arrived at the neighboring Land of That, also a suggestion by Uchiha Yoichi.
Too few people in the Land of Ancestors, and after experiencing a series of events like the Emperor's death today, many are likely fearful, so Uchiha Yoichi suggested Kaguya visit other nations, as her strength is already invincible on this planet.
"That should be a couple..."
Otsutsuki Kaguya saw a pair of men and women, leaning together, aligning with the spouse characteristics mentioned by Uchiha Yoichi.
Now, this pair was preparing to return home, smiles still on their faces.
"They've returned inside, what will they do next?"
Kaguya was curious but didn't want to follow them directly, so she activated the Byakugan.
"Turning off the lights, and removing clothes...What are they doing?"
After watching for a while, Kaguya disabled the Byakugan, feeling that such actions were futile, neither increasing strength nor showing any purpose.
"Let's look at other couples..."
Then Kaguya turned to find other couples, but after observing with the Byakugan, discovered they all engaged in similar acts, thus, curiosity arose.
"Why is everyone doing this, is this a ritual required between spouses? What's the purpose of this?"
With confusion growing, Kaguya walked directly into a couple's house.
After opening the door and entering, she saw a frightened man and woman in bed and asked, puzzled, "Why are you doing this?"
"Who are you? Get out!!"
"Help, there's a lunatic!! Come quickly!!"
The couple shouted in panic, their voices quickly spreading outside.
Kaguya slightly narrowed her eyes, not understanding why these two were shouting instead of providing an obedient answer.
However, recalling Uchiha Yoichi's words, Kaguya directly turned around and left, intending to find another couple to inquire.
As for Uchiha Yoichi, he had created a clone, transformed into the Land of Ancestors Emperor's image, and used Illusion Technique to modify the memories of the Emperor's wife and guards.
Next, he was to investigate the matters of the Yin Yang Master, although it's unclear what will happen next, he must solve the issue with Otsutsuki Hagoromo upon return, as he can't coexist with this guy.
