Naruto went back to Jashin after spending time with his family that night.
In fact, Naruto didn't leave him there alone. There were several clones with Jashin to warn Naruto of a possible thing.
Jashin looked at Naruto with a stubborn look in his eyes. Frankly, Jashin was well aware of what was going to happen to himself.
An enemy had captured him after all, and of course, he would be tortured and questioned by them.
Naruto was going to use Jougan's ability on him, but the conditions for using it were not fully met at the moment. Therefore, he had to break Jashin's resistance first. After that, he could easily learn anything from him, thanks to his technique.
Some people may ask why Rinnegan didn't use one of his ways, the ability. The answer was that Jashin's spirit was strong enough to resist it.
Thus, he began to break Jashin's resistance. There is no need to explain what has been done for this.
Some time passed, and finally, Jashin's resistance was quite broken. When Naruto realized this too, he used his talent to get everything Jashin knew. He absorbed Jashin's body as well, increasing his strength a little more.
Only six people of the Otsutsuki clan survived. Two of them were in the sub-branch, while the others were in the main branch. They also had leaders in addition to them.
Naruto also realized that the Otsutsuki clan knew about him. But they still didn't know where Naruto was.
It was for a completely different reason that Urashiki and Jashin came to where Naruto was.
As Naruto predicted, Jashin had come to the world before. The reason he came earlier was to plant the Juubi.
Jashin had made some contact with the world's inhabitants as he placed it. And he had taught them his techniques.
Jashin was teaching his technique to most places he went, so he became stronger with the energy he got from them.
The reason why Jashin came back to earth was to obtain the fruit of the growing Shinju tree. He had also had a strange feeling for some time from someone who worshipped him.
This person was exactly the type of person who was compatible with Jashin. After marking him with karma, he would take over his body, increasing his strength. But unfortunately, the connection with that person was broken.
The purpose of Jashin coming here was to take the fruit of Shinju and investigate what happened to that person.
The reason Urashiki came with him was that someone needed to be sacrificed for the tree. And since Urashiki was lower to him, of course, he was the one to be sacrificed.
Unfortunately, they met someone they didn't think they would meet.
At first, it was pure luck that Kaguya and Isshiki came to this world. Later, when they saw the energy-rich fruit in the world, they knew that they had to take it.
So the Otsutsuki clan had no idea where Isshiki and Kaguya were yet. If they had known, they would have come a long time ago to find out about their condition.
Naruto also learned about the Leader of the Otsutsuki clan.
Jashin, like Naruto, thought his Leader had something to do with this Jougan thing. In fact, he could have almost witnessed it on one occasion.
One day, Jashin saw one of the people who obtained this Jougan while going somewhere with the Leader of his clan. But later that person suddenly disappeared and was never seen again.
Some people thought that person was killed by one of the hostile races. But of course, Jashin thought that he had been abducted by the Leader and covered it up.
Some people in the clan thought that way. But because of the power the Leader had, no one wanted to go against him. After all, no one wants to be killed all of a sudden.
Also, according to the information he received from Jashin, the Leader had five Jougans. Three of them were on his face, while the other two were in his hands.
He didn't know much about the Leader's powers, but everyone had seen the skills he used while fighting against the Saiyan race. Already after that war, the members of the clan had much more respect and fear towards him.
In that war, the Leader destroyed a massive planet with a single attack and killed many Saiyans living there.
He had also fought alone with the survivors of the planet's explosion, killing them all with overwhelming superiority.
Naruto was not entirely sure of the strength of the Saiyan race. But he, too, could easily destroy a massive planet in an instant with a single skill. So at least he didn't see much difference between him.
The Leader might have had two more Jougans, but Naruto thought he had a lot more energy. Therefore, he felt that he could close this gap with it.
Naruto returned to Konoha after absorbing the body of Urashiki, who was dead.
All he had to do now was to come up with a plan for the future.
But in his opinion, there was no need to come up with such a good plan. After all, the Otsutsuki clan would know they were coming no matter what. Especially if their Leader has a wide field of vision like Naruto's, they will already notice them a while ago.
That's why Naruto wanted to get in there quickly and launch a massive attack before they could react.
Naruto also knew that he couldn't go there alone because his wives had convinced him of this for a long time.
Naruto also accepted this situation quite quickly. Because they were pretty strong, and he thought that each of them was strong enough to defeat at least one Otsutsuki.
