Using Ninja Knowledge

Since Nathan knows his own abilities and limitations, he of course knows that he can't go unnoticed if he doesn't use any support tools.

That is why, using his thoughts, he controlled the drone to go to the entrance of the cave to serve as his guide.

When it was finally at the entrance, he saw himself from the camera of the drone acting like a fool, peeking out of the rock he was hiding in.

Scratching his head embarrassedly, he said, "I'm glad I have the drone."

Then he shook his head and said, "I have no time to be embarrassed. I should start now so that I can go back home before dinner!"

Saying that, Nathan started to move closer to the cave.

Since there was no one nearby, he just calmly walked until the entrance of the cave.

It might be that they did not think anyone would find their hideout, there was no one guarding the entrance of the cave, making it easier for Nathan to sneak in.

When he got inside the cave, through the drone, he spotted someone coming.
