"Blue Moon Island is a special space created with the Tenseigan by Ōtsutsuki Ryūshiki, the first to reach Earth. This space overlaps with Earth and is also linked to the real moon. In addition, the vitality of nature on this land comes from a special form of natural energy called 'moonlight'!"
Hashirama understood at last. "Ah, Moonlight! No wonder I always felt the natural energy on this island was completely different from the outside world... there was an inexplicable, bone-chilling coldness to it!"
Suigetsu said, "Huh? Then that's strange! Didn't you say the sun's energy was the source of all chakra? Are we overturning the established rules at this point?"
Orochimaru smiled. "Not overturning them, but supplementing them. The sun is the source, while the moon can absorb solar energy and transform it through its unique magnetic field. But it has to be the actual moon, not a moonlike celestial body created by Chibaku Tensei!"
Suigetsu said, "I see! As meticulous and thorough as ever, Lord Orochimaru!"
Jugo asked in a low voice, "What did Ryūshiki hope to accomplish by doing this? Why hide the real moon, then create a space like this and link them together?"
"A good question. Please follow me..." Orochimaru smiled faintly, then turned to lead the way.
The group made their way through the forest.
Suigetsu couldn't help recalling an unpleasant memory.
"Lord Orochimaru, how can this island give rise to an 'earthbound spirit' like Danzo? Was that Ryūshiki's doing?"
Orochimaru said, "That was caused by the moon's unique magnetic field. It has nothing to do with Ryūshiki."
After passing through the forest, they reached a gorge in the northwestern part of Blue Moon Island.
Having lived on the island for so long, Sasuke already knew its terrain by heart. He had visited this gorge
