The repercussions of Shisui Uchiha's death were not limited to the Uchiha Clan. They also had a tremendous impact on Konoha's upper ranks.
Although the battle between Simu and Shisui that day had not lasted long, it had caused an enormous commotion.
Moreover, Hiruzen Sarutobi had always deliberately or inadvertently sent people to monitor Root's movements. Thus, when the Wood Human and Susanoo clashed, his gaze had already reached the scene through a ninja-tool crystal ball.
Though he had only been able to glimpse part of it, that alone—the Wood Release Simu displayed and his terrifying strength—had dealt a tremendous blow to the old Hokage's heart.
After all, the Wood Human Technique and Wood Dragon Technique Simu used had been far too similar to those of the First Hokage, Senju Hashirama.
So similar that the Third Kazekage had developed the conviction that he absolutely could not make an enemy of him.
What concerned him even more was that Danzo's Wood Release experiment had actually succeeded.
And after succeeding, Danzo had not chosen to inform him. Instead, he had secretly cultivated such a powerful Wood Release ninja.
What was he trying to do?
As a politician, Hiruzen Sarutobi immediately became wary.
After all, Danzo had coveted the position of Hokage for far more than a day or two. When the Fourth Hokage, Minato Namikaze, had died and he had resumed the post, Danzo had even caused an incident involving the assassination of the Hokage.
Therefore, Hiruzen Sarutobi's guard against Danzo had now risen to the utmost extreme.
But the current situation was that although the Uchiha Clan had lost Shisui, its power remained formidable. He still needed Root to keep it in check.
So now was not yet the time to deal with Danzo...
Still, giving him a warning was necessary.
