As per Narutopedia,
Orochimaru proceeded to don the mask which invoked the Shinigami to possess his body. Orochimaru then cut open the Shinigami's stomach, a wound reflected on his own body, to release the trapped contents inside the Shinigami
We know that Orochimaru used woodWood clones (White Zetsu) to escape from the death. What happened to the Shinigami who got the same wounds ? I know that Shinigami means 'Death God'., but, nowhere itsit's mentioned that itsit's immortal.
