The Black Demon's body suddenly stiffened, a Tremendous Strength surged into its body, scattering all the synergy within.
Chen Fei flipped his hands and pulled his arms outward. In the next moment, he tore the Black Demon's chest in half, cutting off its vitality. It dissipated into a mist.
The expenditure of two Rule Crystals had boosted Chen Fei's power immensely, beyond description.
The number of fragments from the Space Secondary Rule "Minor" had increased from thirty-nine to sixty-seven.
Also, the number of fragments from the Space Secondary Rule "Solid" had gone up from eleven to thirty-nine.
Since Chen Fei had already refined the five kinds of space secondary rules into a single Space Main Rule Crystal, every increment in any secondary rule represented a significant advancement for the Space Main Rule.
It was difficult to specifically describe Chen Fei's current strength by the number of secondary rules he mastered.
