I'm a Demon Lord, So Having a Harem of Dao Companions Makes Sense

Jiang Lin transmigrates to a cultivation continent. Who would have thought that he would turn out to be a demon whom every cultivator wants dead? Luckily, he has the help of a Dao Companion System. “Get a Dao companion and receive a reward?” Supreme cultivation techniques, divine abilities, talents, physiques, magical treasures: it has everything. What, getting multiple Dao companions can also boost my mana and add stat points? If I can just add stat points, why bother cultivating? And so, Jiang Lin devoted himself to finding Dao companions. No, wait. He devoted himself to boosting his mana and adding stat points. And there was no turning back. Many years later, a demon appeared in the cultivation world. The sect leaders, saintesses, and fairies of every immortal academy and orthodox lineage turned out to be his Dao companions.
