Heaven is divided into nine layers.
The residence of the Heavenly Father is located in the highest of the Ninth Layer, also known as Crystal Heaven.
According to Heaven's strict hierarchy, each layer has angels of corresponding ranks. Seraphim reside in the Eighth Layer's Starry Heaven, and Milia, Kiraal, and Vikul, three Cherubim who embody the Seven Virtues, far surpass the status of other Cherubim and are granted entry into the Eighth Layer.
Hexuno led Wayne through layer upon layer of celestial gates, reaching the highest heaven above all others, and stopped with a glance at Heya who was following Wayne.
"What's the matter, Hexuno, why did you suddenly stop?" Wayne asked, knowing full well the reason.
"Lord Son of the Holy, even when the four Seraphim enter Crystal Heaven, they must first request permission. Cherubim do not have the qualification to enter your residence." Hexuno replied with an air of officialdom.
"There's too much personal conflict."
