As time moved into Year 43 of Konoha, Uchiha Chi, having already awakened the Two-Tomoe Sharingan, underwent nearly three more years of grueling cultivation. Finally, right before his fifteenth birthday, he successfully evolved his Two-Tomoe Sharingan into the Three-Tomoe Sharingan.
Upon awakening the Three-Tomoe Sharingan, Uchiha Chi felt a certain dormant power within his bloodline being gradually released, guided by the newly formed tomoe. This power was not only stronger than when he had awakened the Two-Tomoe Sharingan, but it was also continuously flowing, albeit gradually weakening.
Well-prepared, Uchiha Chi used the Meditation Technique—a method he and Uchiha Chiri had researched together—to actively guide this power and continuously strengthen his body.
