['Flandre' tells you that the star body, which looks as if it can be traversed with ease, is not the case; it's obstructed by considerable power. To reach the ninth layer of the Holy Nest, you must possess the 'Order of Audience'.]
After Lin Xun killed 'Painbearer Belatu', he found a key item called the 'Order of Audience' among the spoils of war.
This undoubtedly corroborated Flandre's speculation: all offspring reside in the ninth layer at the heart of the Holy Nest.
It seems that after the clone of 'Belatu' was reincarnated and awakened, if it had not encountered them, it would have used the 'Order of Audience' to pass through the barrier and reach the Temple of the Flesh of the Wet Nurse.
[After 'Flandre' finds out that you have the 'Order of Audience', it asks if you will continue to search in the eighth layer of the Holy Nest or proceed directly to the ninth layer?]
