89 Sage mode

Sitting crosslegged, a boy was mixing within the Darkness, his presence seemed very faint, if anyone was around they would have a very hard time noticing him, even if they stood only a few meters away from him and looked straight into his direction all they would think while seeing that spot was nothingness.

It has been more than a week since Kayle started his training on Senjutsu, he had already tried in the past when he had just reached the chakra reserve of a Jonin, but due to lack of time then he didn't get much progress, but right now, the young child was wholeheartedly focused on his training with nothing else in his mind.

Kayle was now sitting at the very top of the Shadow tree, behind him was the sacrificial hole where the corps of the Neko-clan were returned to, Kayle was completely still as he focused on the entry going out of that specular place.

The first time he visited this place Kayle had tried to find what was inside the whole with no success, nothing could be seen from the outside at all, a hole of complete darkness was sitting there, and anything that went inside would disappear once inside. Kayle had also made several experiments and he found several things.

First, if anything was thrown inside it would be very hard to retrieve or almost impossible the only solution Kayle found was to attach that object to a string, as long as the object was in direct contact with something then it could still be retrieved. Secondly, this entrance looked a lot like a black hole, once something went inside it couldn't be seen from the outside at all. And Lastly, if any living thing entered inside the Chakra would be consumed at a very fast peace.

Kayle had put his hand inside once and all his chakra was consumed within ten seconds, Later when Itachi mastered the darkness Senjutsu he too tried to explore the hole but he didn't have much success either, Itachi made the discovery that while in the Darkness mode the chakra would be consumed much more slowly but even with his huge reserve Itachi couldn't reach the bottom of the hole, he had to turn back after descending around the third of the estimated distance, and that was if the final destination was around the roots of the tree, Kayle wasn't even sure if this hole went even deeper than the ground level.

Since the Party and his goodbyes with his friends, Kayle had been sitting motionless all this time while staying as still as a rock, even if Kayle hadn't Senjutsu outside, he had still made some preparations as he remembered how being one with nature had helped Naruto in his training, Kayle had made similar exercises to improve his balance to an incredible extent.

On the first day of his training, Kayle could already feel the strange darkness energy emitted from the hole.

One week later Kayle could integrate some of this energy inside of his body, one could see a faint gray mark under his closed eyes, and unlike Mount Myōboku, in this dimension, there was no stick that could help expel the Senjutsu Chakra inside one's body, Kayle had to be very careful to take and integrate very small quantities of Darkness Energy inside his body as he started training as he didn't want to be consumed by the darkness and disappear inside of the hole behind him.

After Two weeks of training, Kayle could feel that the Darkness energy all around the world, it was very scarce but at least now he could feel it, he had also made a lot of progress while trying to master the Sage mode and he felt an incredible sensation as he could feel a huge area around him. While sitting on top of the Darkness tree, Kayle could feel and see everything happening down below him. He could see the children of the Uchiha playing with the Neko-clan, he could see a few parents preparing meals of framing, Kayle felt that he could finally experience what a Sensor Type Ninja could feel.

On the third week Kayle had finally completed the mastery of his darkness sage mode, he could go into this mode even without relying on the Darkness tree and he finally decided to visit Tora to learn a few techniques from him.
