@BigBad The issue with that is that Asura and Indra's chakra only incarnates into their descendants, and chakra is in your DNA, as proven in Madara's case. If you're a Transmigrant Uchiha, you will need the Transmigrant Senju's "Body" to awaken Rinnegan, or if you're a Transmigrant Senju, you will need the Transmigrant Uchiha's "Eyes" to awaken the Rinnegan. If you're just some normal person, you're gonna need to take the "Body" and "Eyes" of a Senju and Uchiha who are Asura and Indra's incarnates to awaken Rinnegan. I highly doubt just absorbing or having them both transfer some of their chakra to you will allow you to awaken it so easily. Especially since it took so long for Madara to awaken it, he was elderly, and he was an actual Transmigrant.
