Once those words came out, all the four ghosts were completely stunned, their eyes filled with incredulity.
"Young….. Young Master said he possesses a methodology manual for ghosts to cultivate?"
Could….. could that really be true? It must be known that manuals for devilry cultivation was a whole lot harder to find than one for cultivators! When they had still been human in this world, they had only merely heard of it but had never seen it before.
If they were to have the methodology manual to be able to become devilry cultivators, then they would not have to worry about their Yin energy depleting and become unable to survive here under these Heavens! Moreover, once a devilry cultivator cultivated to a certain level, they would not need to fear the rays from the sun anymore! Then even in the day, they would be able to move about freely.
It must be said that those words posed an irresistible allure to all of them.
