Just take a look and don't care.
A college student stayed up late to cultivate immortality and traveled through the HP world. In 1981, when Neville and his parents were tortured, he entered Neville's body and merged with Neville's soul, but he had an independent and independent consciousness, as if he was schizophrenic, but he could communicate with Neville. Originally he just wanted to watch the world develop freely, but he was not the only one with bugs. Snape actually began to doubt himself. Alas, there seems to be something different between Snape and Harry. It turns out that Snape was also reborn.
