The specific recovery speed is related to the resources obtained; the more souls and blood-flesh essence, the faster his strength will recover.
His True Body is comparable to a Medium Divine Power of Innate Titan Ancient Gods, combined with once True Body in the Wizard World and the soul that became incredibly powerful after devouring countless other souls—the unity of these three factors means it won't take long for his strength to enter the Rank 8 echelon, becoming one of the top powerhouses of this world.
In the Wizard World, Medium Divine Power, Powerful Divine Power, and Super Divine Power all belong to the Rank 8 echelon, which also represents the level with the greatest range of power.
Once he reaches that stage, even without the strength bestowed by the All-Embracing Progenitor, he can ensure his memories will not be lost.
