Isshin's special physical clone skill was precisely what he had gained after integrating the Great Slug Sage's bloodline genes.
The Great Slug Sage truly lived up to his status as the ancient being with the greatest vitality on this planet. Both integrations involved secondary bloodlines, yet Tripitaka had gained only some spiritual energy and a One-Tomoe Sharingan born from that energy—roughly the equivalent of a green trait's enhancement. Isshin's results, however, were completely different.
After the successful integration, the boost to Isshin's vitality and his ability to sense and absorb natural energy together amounted to roughly two green traits. In some respects, Shinichi even felt they were approaching the threshold of a blue trait.
Beyond that, this integration had also given Isshin a skill with a unique mechanism—or rather, an innate supernatural ability: he could turn part of his own body tissue into a physical clone.
Because it closely resembled a certain monkey's supernatural ability from his previous life, Shinichi had named it "Hair Clone."
Still, the slug bloodline was ultimately only a secondary bloodline, not his primary one. At present, Hair Clone fell far short of Bronze Head Iron Arm, the innate skill Isshin's primary bloodline had granted him through the Enma King.
Bronze Head Iron Arm was a genuine miracle of physical prowess. Even the Third Raikage had suffered badly against it, whereas Hair Clone remained largely a support ability at this stage. The gap between them spoke for itself.
First Bronze Head Iron Arm, then Hair Clone. Shinichi could not help finding it a little amusing, and he quietly pondered the matter.
Did integrating the bloodline genes of these native creatures make it especially easy to develop skills resembling innate supernatural abilities?
Moreover, unlike Tripitaka, whose strength had shown no noticeable change after integrating Uchiha Madara's bloodline
