Heavenly Tribulance
After unsealing the 1st seal of the Dracul Wolf Family, Ezra's body had grown even more and was now perfect to hold an abundance of spiritual energy. All that was needed was an opportunity for him to smoothly store more in his core than the rest.
Normally speaking, for those who did not practice any body tempering methods, when their martial prowess reached the Core Formation stage, their body would still strengthen. However, this boost was limited, and most would only reach a smaller level than those with body tampering methods.
In comparison to Ezra's perfect Golden Pelt and strong Bloodline, the distance between them was tremendous.
Therefore, at the very least, Ezra's body would give him a huge advantage at the Core Formation level.
With these thoughts in mind, Ezra decided not to waste any more time. His energy extended, seemingly transforming into numerous giant invisible hands that began to scoop up the tiny streams of world essence energy.
