Sacrificing one's bloodline was a special enhancement spell technique exclusive to the Dragon Tribe.
It could bestow upon a dragon an extraordinary power in a short period of time.
An Lin had once seen Bei Lian unleash the same type of spell technique in order to save his life.
There were very severe after-effects to using this spell technique. Best-case scenario, one's bloodline purity would be compromised, thereby making it very difficult to progress through the cultivation bases in the future, and in the worst-case scenarios, one's cultivation base could even fall.
Most dragons wouldn't use this type of spell technique as it was the equivalent of giving up on one's cultivation path. Powerful Return to Void Stage mighty figures would be even more reluctant to do so.
However, all three Return to Void Final Stage evil dragons had just used it without any hesitation!
