Shinji was actually quite good at simplifying complex problems, so in his understanding, the reason Kimimaro was able to enter a temporary Tenseigan state beyond his expectations boiled down to a few key elements.
First, Kimimaro pushed his own Shikotsumyaku Chakra to the absolute limit, which should also be the source of Kimimaro's bloodline disease.
Second, in an extremely short period of time, Kimimaro received a massive surge of Chakra stimulation.
Third, the Chakra that stimulated Kimimaro was delivered by the other half-set of biological exoskeletons, which possessed almost no rejection.
Fourth, the delivered Chakra was Byakugan Chakra, which could complement Kimimaro, and Tenseigan Chakra, which could sublimate and fuse the Chakra.
Although the fourth point seemed the most important, the first three elements were actually indispensable.
Without Kimimaro developing his own Shikotsumyaku to the limit, without the massive amount of Chakra stored in the biological exoskeleton, and without the concerted cooperation of the two half-sets of biological exoskeletons that resolved the rejection, even with Neji's Byakugan Chakra and Tenseigan Chakra, the miracle just now could not have been accomplished!
Having sorted all this out, Shinji gave Kimimaro a deep look.
It was just as he had foreseen.
The number one person in the Shinobi World most suited to awakening the Tenseigan was actually not someone from the Hyuga Clan who possessed the Byakugan, but rather Kimimaro, a supreme genius of the Kaguya Clan who also flowed with the blood of Hagoromo Otsutsuki!
Hinata and Hanabi, the two members of the Hyuga Main Family, as well as Neji of the Hyuga Branch Family, were all a cut below compared to Kimimaro.
It was not until Shinji finished asking all his questions that Kimimaro asked, "Lord, what on earth just happened to my eyes?"
Shinji shook his head and did not
