After breaking through, Chu Xuan's next step was to fully utilize the Heavenly Dao laws in the Northern Zone to increase the overall strength of the Northern Zone.
When he looked down at the Northern Zone, Chu Xuan saw many secrets hidden there.
Whether it was ancient battlefields or mystic realms, none could escape his gaze.
The blood fiend race in the ancient battlefield was what Chu Xuan valued the most.
The blood fiend race was very special. They could be revived with the help of the blood-colored spiritual energy.
Even if they were completely incinerated, as long as the blood-colored spiritual energy existed, new blood fiends would be born.
They were practically immortal!
Moreover, the blood fiend race was brutal, bloodthirsty, and violent. They were truly a race born from the calamity.
The ninth Great Daoyuan calamity was indeed very terrifying.
