After resolving the problem of controlling the ghosts, Chen Mu's life returned to regularity.
Every day he practiced the Jade Cicada Secret Scripture, steadily progressing in Daoist Foundation cultivation, and during his rest, he continued to ponder the Plague Immortal Technique.
Every three to five days, he caught a strange demon, and the number of ghosts in the Five Ghosts Bag quickly reached twelve thousand.
As if coexisting symbiotically, the internal space of the Five Ghosts Bag began to slowly expand under the influence of the ghosts.
"There must be some profound mystery between the two," Chen Mu realized.
The practice of the Five Ghosts Bag came from the Thousand Mountains Sutra, and the Five Ghosts Paper Dolls, one of its cores, were made using ghosts.
"Perhaps only the complete Thousand Mountains Sutra records it, but unfortunately, it's nowhere to be seen."
The Thousand Mountains Sutra is widespread, but most are fragments.
