Furthermore, through Uchiha Chi's in-depth research and comprehension, he also discovered that there were two different ways to utilize his eyes' Dojutsu when they mutually amplified each other: in the first scenario, one eye would assist the other in executing a Dojutsu. In this way, the effect of the Dojutsu remained unchanged, but the consumption of Pupillary Power was reduced to half of the original amount.
Once the Dojutsu was successfully cast, the degree of fatigue felt by the eyes would also be lessened. Moreover, as long as it was not used frequently in rapid succession, there was basically no impact on his vision for the time being. This technique required a sufficiently high level of personal comprehension, as well as enough proficiency in the application of the Mangekyou and Dojutsu to comprehend and master it.
The second scenario was a hypothesis he formulated based on the first, but this method inflicted far too much damage on himself, so he never dared to try it lightly, instead treating it as his ultimate trump card.
