Liao Wu had not taken Hikari's eyes. He simply felt that her Yachihoko Dōjutsu was too powerful. It was her overwhelmingly powerful Yachihoko that had caused her tragic suffering.
Liao Wu only wanted to share some of her pain and tragedy.
He was still a kind Uchiha.
The Rinnegan on Liao Wu's forehead met Hikari's left eye. Then Liao Wu activated Daikokuten and seized the Dojutsu in her left eye.
Boruto's Karma had stopped working, leaving him only able to bite Liao Wu's leg like a rabid dog. The other Uchiha clansmen grabbed Boruto and pulled him away.
The instant their eyes met, Liao Wu took the Yachihoko from Hikari's left eye into his Rinnegan. A pattern appeared within it—the pattern of Hikari's Mangekyo.
Centered on the pupil, three symmetrical, arrow-shaped black markings radiated outward like a pinwheel, arranged at equal intervals around a circle to form a three-spoked Mangekyo.
Its outline resembled Itachi's three-tomoe pinwheel, but the markings were arrows rather than curved tomoe.
Then Liao Wu activated Daikokuten again, rolling back the Dojutsu in his right Mangekyo and using Daikokuten to plunder both it and its pupil power into the Rinnegan on his forehead.
The Mangekyo in his right eye was completely ruined. Liao Wu simply plucked it out and tossed it off the cliff.
Under the control of the Chimera Technique, the Rinnegan moved into his original right eye socket.
Now Liao Wu's eyes looked much better.
Although the third eye on his forehead had looked cool, it had also been extremely strange, without any aesthetic appeal.
A normal pair of eyes, one on the left and one on the right, looked much better.
Hikari called out to Liao Wu, "Take all my Dojutsu!"
"Huh?!"
Liao Wu was a little stunned.
But Hikari had her own explanation.
