300 Fierce Battle

"It seems that the declining diagram is enhancing the Primordial Spirit."

Zhou Bai thought of the Lazy Diagram that enhanced physique and defense, the Poor Diagram that enhanced speed, the Ugly Diagram that enhanced aptitude, each layer of the Nine Calamities of the Celestials seemed targeted. In the end, it would probably comprehensively enhance every aspect of a cultivator.

"It just so happens that my Primordial Spirit power is not the strongest among my peers, and the Tianhe Star Explosion Sword also needs strong Primordial Spirit power to support it to unleash greater power."

Zhou Bai smiled, thinking, "This layer of the declining diagram can greatly enhance my attack power."

Therefore, Zhou Bai spent another 300,000 Lazy Points to inject into the 'Yin God - Corpse Dog' star point.

Instantly, Zhou Bai felt his Primordial Spirit contract and then expand, his brain conveying bursts of stabbing pain as if a steel knife was scraping within his head.
