The moment Zatiel reached the void, he did not wait before adopting a meditative position and channeling Elemental Chaos into the True Doomsday Body's fourth heaven. A white whirlwind appeared inside the Neo-Demon's hearts.
A similar whirlwind, but millions of times larger, appeared above a flaming star in the Neo-Demon Realm's void.
While a Neo-Demon can choose some of the stars according to his personal preferences, the one in the hearts and brain must contain the Yang Law and Yin Law, respectively.
A genius Neo-Demon who developed his foundation with hard work would always be able to seal a star one Tier higher than the previous one.
Those who obtained great lucky chances, pushed themselves to their absolute limit, and used the best resources could seal a star at the peak of the Tier. A Peak Tier 4 Star is around seventy to one hundred and fifty percent stronger than a Low Tier 4 Star.
