Chapter 283: Ch.283 Success Is the Only Option!
The more he mulled it over, the more excited Uchiha Shinji became.
As the core figure in his 'Rinnegan Plan,' Karin's strength was the key to whether the 'Rinnegan Plan' would succeed.
And to increase the plan's success rate, both Karin's Yang Release chakra and Yin Release chakra had to reach their absolute peak!
On the Yin Release chakra front...
As long as Karin could restore her fully depleted Mangekyo Sharingan this time, Shinji was at least thirty percent confident he could help her fuse them into an Eternal Mangekyo Sharingan.
Though it wasn't the ultimate peak, it at least met the threshold to pursue the Rinnegan.
As for the Yang Release chakra front...
As a member of the Uzumaki Clan, with a healing physique exceptionally rare even among her kin, Karin's Yang Release chakra was already formidable.
Add to that the White Zetsu cell transplant Shinji had previously performed on her, which had further elevated the quality of her Yang Release chakra.
At this point, it was essentially at its limit.
If he wanted to push Karin's Yang Release chakra even further, the only path left was to directly transplant the First's cells.
