Orochimaru had no desire to bring his biological parents back through Impure World Reincarnation.
Since Yanbai did not ask why, Orochimaru said nothing more about it.
Perhaps Orochimaru had never been particularly close to his biological parents, and would not know what to say even if he summoned them.
Or perhaps outsiders simply could not understand Orochimaru's view of life and death.
From then on, however, Orochimaru became even busier. He often spent the night at the Konoha Research Institute, and even took Itama and Yuna's reincarnated bodies with him.
According to Orochimaru, he had disturbed his parents' eternal rest. Yuna and Itama's reincarnated bodies had spent so much time helping him copy records that they had become his personal scribes, frequently occupying Yanbai's study.
