Chapter 367

Icarus felt a ball of heat exploding in his body. The warm sensation flowed through his body in an instant. A few dull thuds rang from within his belly, and golden rays radiated from within his bones. He felt an excruciating pain like his organs were on fire. Gritting his teeth, he endured the pain and cultivated the power core, just like how he did with the demon beast's inner core. At first, the power core did not respond to him. However, it started releasing wisps of pure spiritual energy once he completely wrapped it up in his spiritual energy. Just like he had guessed, the power core contained a high concentration of spiritual energy. After his discovery, his eyes gleamed in excitement despite the waves of pain in his body. For Icarus now, the lower-level demon beast's inner core was of no use, but the high-level demon beast's inner core and spiritual river were hard to come across. The discovery of the power core introduced a new way for him to elevate his cultivation phase.
