The scroll sent by the Great Toad Sage looked extremely ancient, with at least several centuries of history behind it.
The Great Slug Sage's scroll, meanwhile, looked freshly made. Some sticky liquid still clung to it, and it had likely just been delivered from Shikkotsu Forest. It should have contained Shikkotsu Forest's Sage Art.
After all, the Sage Arts of the so-called Three Great Sage Regions were merely methods created by the three Great Sages according to their own circumstances to absorb Nature Energy. At their core, they all converted Nature Energy into Chakra.
After several hours of reading, Naruto had committed the cultivation methods of Mount Myōboku and Shikkotsu Forest to memory.
After comparing the Sage Arts of the Three Great Sage Regions, Naruto was surprised to discover that the three cultivation methods were largely similar. They seemed more like they had originated from the same method, differing only in emphasis.
Mount Myōboku leaned toward the atmosphere, while Ryūchi Cave and Shikkotsu Forest leaned more toward the earth and sea.
Moreover, because the creatures were different species, their cultivation methods also differed greatly, placing greater emphasis on their true forms.
After leaving the Toad Temple, Naruto chose a stone platform facing a stream. He formed hand seals and created two Shadow Clones, then began condensing Sage Chakra through different cultivation methods.
Naruto had long mastered Ryūchi Cave Sage Art, and he had already heard much about Mount Myōboku's Sage Art.
The only difficult one left was the cultivation method from Shikkotsu Forest. But with the parallels he could draw, learning Shikkotsu Forest's Sage Art was practically guaranteed.
Time passed swiftly in cultivation, and in the blink of an eye, three days had gone by.
Over those three days, quite a few toads came to watch Naruto cultivate Sage Art.
