Yuan Biyao was certain that after any flux expert from the outside personally witnessed the strength and reserves of the Origin God World, they would lose all hope and wouldn't try to escape.
After all, the only path to the Origin World was through the twelfth layer of World Ancestor's twig which meant the bloom.
What sort of people lived in that region?
They were the upper echelons and imperial clan of the Origin God Sect. Every person who had the qualification to stay there was at least a sage flux expert.
Naturally, people like Yuan Biyao who were related to Yuan family as well as some of the servants who were ordinary people were an exception.
The bloom of the ancestor tree could be said to be the most formidable region where all the powerhouses of the Origin God World were concentrated.
Even the gold serpent kings of the Underworld Serpent probably wouldn't have the slightest chance to infiltrate that place.
