On the night of Uchiha’s extermination, my shirunan turned black

After crossing over to Uchiha, Zanyue became the Jounin of the Uchiha clan.

On the night of Uchiha’s extermination, a notification sounded in Zhanyue’s mind as he prepared to fight Itachi to the death.

[Hint: Your Shura Eye has seen the death of your clansmen. Anger 1.]”

[Hint: Your Shura Eye has heard the wails of your clansmen. Rage 1.]”

[Hint: Your Shura Eye’s rage has exceeded the critical value. It has turned black!]”

"Hint: Your Shura Eye has obtained the Darkening talent--”

[Hint: Your Darkened Shurakan has released ’Encouragement’ on you. Good luck, brain!]”

Blackening was ten times stronger, but whitewashing was three times weaker.

Moon Slaying killed Yuan Fei and Sun Slaying’s son with a single blade and then announced,"

"From today onwards, I, Uchiha Moon-Slaying, will defect!”

"The next time we meet will be the day of your Yuan Fei Clan’s extermination!”
