Tsunade left Shikkotsu Forest to enjoy herself, but Gengetsu had it nowhere near as easy. He reviewed the experiment summary once more, then entered another laboratory after pondering for a moment.
Four Split Clones who looked almost identical to him were conducting dissections and research on their respective bodies.
Gengetsu Sun, Gengetsu Star, Gengetsu Celestial, and Gengetsu Thunder. In truth, there had originally been more than just these four Split Clones—there had been eight in total. Unfortunately, the first four had all died, including the very first "Gengetsu Sun."
Before becoming a sage, clones split off in Sage Mode had a fatal weakness: their souls and minds.
Though Split Clones appeared to have copied a complete soul from the original body, they were actually shaped from Sage Chakra using mental energy. They were far weaker than the original, and once their consumption became too great, they would collapse.
So, the experiment he had initially wanted to conduct had clearly failed as well. It was simply impossible to use the Unity of Heaven and Man state to rapidly undergo Sage Transformation, and his attempt to make Split Clones into permanently existing clones had naturally failed too.
"Clearly, if I want permanent clones at present, I have to become a sage..."
Sighing inwardly, Gengetsu stepped forward and gathered Gengetsu Sun and the other three for discussion, their thoughts colliding.
Though they were clones, they possessed independent consciousness. Moreover, because they were in the Unity of Heaven and Man state, Gengetsu Sun and the others were, in some ways, far more "intelligent" than Gengetsu, the original body.
What he needed to do now was work with the four clones to further refine the Yin-Yang Seal they had previously developed, then combine this Sealing Technique with the Four Symbols Sealing, Eight Trigrams Sealing Style,
