Chương 567: ❮Diary of the Ascetic Senior Monk❯

Song Shuhang's ghost spirit had already recovered and returned to being a middle-rank ghost spirit. In addition, there was a runic core inside its body, something that only high-rank ghost spirits could possess. Thanks to the runic core, there was a small chance that Song Shuhang's ghost spirit could also evolve until finally becoming a high-rank ghost spirit in the future.

Middle-rank ghost spirits had already a pretty good intelligence. On the other hand, high-rank ghost spirits had a level of intelligence that wasn't inferior to that of a human being. The speed of their cultivation was faster than ordinary cultivators', and they could also learn certain ghost-type magical techniques.

After Song Shuhang completed the synchronization with the ghost spirit, the latter slowly started to transform into a high-rank ghost spirit.

Although its current rank was still that of a middle-rank ghost spirit, it already had an incredibly high level of intelligence.
