"What a feeling."
After mastering the Red Eyes, Shinji savored the sensation and then wore an expression that said he'd expected as much.
Just as he'd guessed.
Using the Susanoo Lamp to master the Red Eyes worked far better than using it to master a pair of Mangekyō Sharingan.
Although Night Owl's Red Eyes possessed far less Dojutsu than Fugaku's Mangekyō Sharingan,
mastering the Red Eyes had boosted Shinji's Dojutsu far more than mastering Fugaku's Mangekyō Sharingan!
"My guess was right! Only by mastering different kinds of ocular jutsu can I maximize the increase in Dojutsu!"
Shinji's face lit up.
Now that his theory had been confirmed, he had a reliable way to greatly increase his Dojutsu: collect all kinds of Kekkei Genkai that granted ocular jutsu!
Then Shinji turned his gaze to the other small nutrient tank in front of him.
Inside was another pair of Red Eyes he'd acquired.
After a moment's thought, he took out the pair and activated the Susanoo Lamp again, mastering these Red Eyes as well.
Once he'd succeeded, two of the three pairs of eyes in his Susanoo were Red Eyes; only the remaining pair held his own eyes.
"Huh?"
After sensing the change, he suddenly frowned.
He'd discovered that mastering a second pair of Red Eyes had noticeably increased his Dojutsu again. The boost wasn't as significant as when he'd mastered the first pair, but it still clearly exceeded the boost from mastering Fugaku's Mangekyō Sharingan.
"Why did mastering a second pair of Red Eyes also give me such a significant boost?"
He rubbed his chin.
He could understand why mastering the first pair of Red Eyes had worked better than mastering the Mangekyō Sharingan, but the fact that mastering a second pair had also surpassed the Mangekyō Sharingan left him puzzled.
