In general, the specific situation of the immortal cultivation level division and the upper limit of life needed to be determined according to the specific immortal cultivation novel.

Naruto could achieve an absolute defense by combining different ninja techniques. He might merge his Rasengan with a sealing jutsu to create a spherical defense that is both offensive and defensive. The Rasengan's spinning chakra could be harnessed in a way that it not only attacks but also forms a shell around him that nothing can penetrate. Also, his experiences in different battles might lead him to innovate a new jutsu specifically for defense. For instance, after facing a particularly difficult opponent, he figures out a way to reverse the flow of his chakra to create a repelling force that acts as an absolute defense.
