Orochimaru scolded as he sat in his office with a angry expression on his face as they last few years hasn't been too kind to him.
So far Sasuke had been training extensively and hasn't even unlocked his sharingan yet which was frustrating in Orochimaru's eyes as he tried everything to help Sasuke unlock his sharingan even killing Sakura and Sasuke In front of him did nothing.
Now while Orochimaru had Kakashi sharingan in his possession, he needs another one to finally unlock the secret of immortality but there's a slight problem.
If Orochimaru needed another sharingan eye he would need to go into Konoha but there's a possibility that he might run into Tsunade, Jiraiya or Naruko.
Orochimaru wasnt looking for a fight especially since the war between Konoha and Otogakure would be happening soon, so he needs all the rest and strength he could get.
Orochimaru couldn't understand why Sasuke couldn't unlock his sharingan but maybe the answer will become reality when Orochimaru destroy Konoha.
