Not only is he not dead, but he has been alive. In 334, orochimaru didn't die, because if we look back, we know that in 358, orochimaru was also released from Sasuke by a skunk. From this perspective, orochimaru has never died, and orochimaru itself is very powerful. It is impossible to kill orochimaru with Sasuke who hasn't killed a skunk for 334 years, and orochimaru has cells in his body. Orochimaru has super wireless regeneration capability. Even Sasuke's strength is given by orochimaru. When the ferret defeated Sasuke in episode 358, orochimaru was still telling Sasuke to release the power of orochimaru. It can be seen from here that Sasuke didn't kill orochimaru. Besides, even if orochimaru is weak, Sasuke can't recruit KO, but it is very likely that Sasuke was recruited by orochimaru. Orochimaru was originally a master of forbidden arts and endured genius. As an AB, I haven't started yet. I am looking forward to how to write it.
