Experimenting with Dark Release?

Decades ago, under Zetsu's guidance, Uchiha Madara transplanted Senju Hashirama's cells and awakened the Rinnegan before his death, allowing him to cling to life.

Zetsu seethed with indignation.

At this moment, Kisame Hoshigaki recounted in full everything that had happened after the two of them encountered Deidara. Finally, he provocatively said, "Leader, Uchiha Houka
