Shusen was shocked—and afraid.
At that moment, he became incredibly curious about the ocular technique Izuna had awakened.
He could be certain that if he had not used a Shadow Clone as a buffer, and Izuna's ocular technique had targeted his real body directly, he might truly have been killed for no apparent reason!
Even worse, if Izuna's eye power had risen another level and evolved into the Eternal Mangekyo Sharingan, he might very well have been able to erase him directly through a Shadow Clone.
At that thought, Shusen immediately felt that his life was no longer secure.
No, I need to seal Izanagi in my Mangekyō Sharingan beforehand. That way, even if I suddenly die, I can come back to life. At worst, I'll lose one Mangekyō Sharingan. He began calculating how to counter Izuna's ocular technique.
Although his identity as Black Zetsu had not been exposed, and Izuna might not necessarily want to kill him, he still had to prepare for the worst. Nothing was more important than his life, and no one was going to kill him for no reason.
"I have to say, Izuna's ocular technique is truly formidable. Compared to his method of using causality to lock onto and kill people, my Lesser Kotoamatsukami falls short by who knows how much."
"If only I could gouge out his Mangekyō Sharingan and transplant it into myself..."
Shusen had a bold idea and began plotting to claim Izuna's eyes for himself... Such a dangerous ocular technique would be safer in his care.
In the original story, Izuna would ultimately die at Tobirama's hands. Madara would gouge out Izuna's Mangekyō Sharingan and fuse it into a brand-new Eternal Mangekyo Sharingan by transplanting his younger brother's eyes. Shusen felt that perhaps, on the day Izuna died, he could
