Mortal Cultivation, Demon Immortal

[A demonic immortal, dark, cruel, no harem, no system, slow to warm up]
[Not a saint, dark, beware!]
My master sent me to the immortal path, I helped my master go to hell.
In order to seek a chance of survival, I murdered the people around me.
In order to improve my qualifications, I slaughtered thousands of cultivators.
Yi Han, with his mortal qualifications, plundered the fortune of heaven and earth and reached the pinnacle of the demonic path.
