"Kushina, how is your senjutsu training coming along?"
Qingyun held Kushina's hand as he asked.
"Pretty well. Once I enter Sage Mode, my recovery and strength improve quite a bit, and it even boosts the power of my Seal jutsu!"
Kushina answered with a proud look.
"Is that so?"
At her words, a thoughtful look flashed through Qingyun's eyes. The original story had never clearly explained the abilities of Shikkotsu Forest's Sage Mode, nor had it even explicitly identified any ninja who had mastered it.
It was just that Hashirama Senju's appearance in Sage Mode differed from those of Mount Myōboku and Ryūchi Cave. Moreover, the physical recovery he displayed, the power of his Gate of the Great God, and the range of his Wood Release all resembled Shikkotsu Forest's characteristics, leading to speculation that his Sage Mode had originated there.
Only now, after hearing Kushina describe Shikkotsu Forest's Sage Mode, did Qingyun confirm that Hashirama Senju's Sage Mode had indeed come from Shikkotsu Forest.
Unlike the other two sacred lands, Shikkotsu Forest had only one living being: the Slug Sage. Her abilities leaned toward support, but even so, they were extremely powerful.
With enough chakra, she could divide herself and heal an entire village's ninja. In effect, she could match all the medical ninja in a village combined, and she could even perfectly heal injuries that some medical ninja could not treat.
Besides that, she could transmit chakra, share her summoner's vision, relay intelligence, and resist physical attacks by splitting herself apart.
Shikkotsu Forest's senjutsu also focused on support, enhancing the user's cellular activity to improve their recovery while boosting their strength and the power of their Seal jutsu.
From that perspective, although it lacked the other two sacred lands' unique senjutsu techniques, Shikkotsu Forest's Sage Mode suited Kushina
