440 Will be enough

Zatiel stood in the void for eight months, devouring oceans of Elemental Chaos as he inscribed All-Devouring Seals and formed the first layer of channels that connected his body to the domain.

As he enhanced his understanding of the All-Devouring Domain, the Elemental Chaos inside the Spiritual Endless Ocean improved. The Neo-Demon's energy pool was not bound to the True Soul's power anymore, and it could grow much larger than the Soul Origin.

The All-Devouring Domain also helped the Neo-Demon's body to adapt faster to the fourth Apocalyptic Star's pressure. 

All of a sudden, Zatiel opened his eyes and looked toward the White Sun. A message from the NRAI showed Heinz, Zitra, Sophia, Totto, Tyrus, Juntu, Dante, Kylo, and Rax appearing in the Beta Heavenly World.
