The difference between dark spirits and evil spirits was that dark spirits were formed by a person's heavy resentment after death. They often carried a strong grudge while evil spirits were born from devouring the souls of the dead. The former contained murderous resentment and the latter had no consciousness, and only knew to feed on Celestial Chi, souls, and flesh and blood. Dark spirits were often stronger than evil spirits.
Ye Chen wondered why this dark spirit was locked here.
Ye Chen's Astral Body swept over the dark spirit and seemed to freeze instantly. The cold dark energy exuding from the dark spirit made Ye Chen shiver.
What a terrifying dark spirit!
The power of this dark spirit was simply unfathomable. Ye Chen could not tell its true strength at all!
Hum hum hum!
At this time, the Soul Pearl on Ye Chen's chest started vibrating and issued a fierce warble.
