If Lin Xuankong intends to practice the Demon Technique, it won't be that difficult!
Whether it's the Thousand Illusion Celestial Demon Race or the Ten Thousand Laws Celestial Demon Race, or the Profound Yin Demon Race of the Golden Dragon Immortal Realm,
they all possess Demon Race cultivation techniques that, in conditions of extremely scarce Spiritual Qi, involve killing other life forms and absorbing their Life Force and Energy!
Additionally, every Demon Race, including the Profound Yin Demon Race, has cultivation methods that absorb the power of fear and hatred from others' Divine Souls through torture!
Lin Xuankong learned these two cultivation methods of the Demon Race from the cultivation technique tomes of the Profound Yin Demon Sect in the Golden Dragon Immortal Realm, and can use them at any time!
