20,000 meters deep on Earth.
Chu Zhou sat cross-legged in the space opened by the Thousand Star Vine. Two Profundities, Berserking and Nine-Tiered Hell, appeared in his mind.
He had comprehended these two Profounds from the Book of Profound during this period of time.
The Book of Profound was one of the three treasures of the Woox civilization that he had obtained from the fifth ruin controlled by the Human Alliance.
Among them, there were 36 Profounds recorded. The Incinerating Fire, Tremor Punch, and Rainstorm that he had comprehended previously were also recorded.
The reason why he chose to comprehend the Profoundities of Rage and Nine Hell was based on the situation he was facing.
The Rage Profound could make his essence, qi, and spirit boil and his strength increase explosively.
He was now facing the pursuit of the three organizations and the monsters, so he naturally needed enough strength to deal with the enemy.
