In fact, over the years, they have had their own interpretations regarding the internal division of those at the Apostle Level. Some apostles categorize them into upper, middle, and lower levels, while others evaluate them from Apostle Level 1 to 9 within themselves. Some only recognize Tier Six compared to other ordinary apostles. Unfortunately, there has been no unified planning, and many base it on their self-assessment.
However, only Xue Dili has unified the measurement standard for what seems to them a "trivial matter".
In the standardized system established by Xue Dili, the internal hierarchy of the Apostle Level is divided according to titles, namely: King, Duke, Marquis, Count, Viscount, and Baron, representing six more detailed divisions of strength within the Apostle Level.
The apostles at the Marquis Level are quasi-Tier Six, while those at the Duke Level are infinitely close to quasi-Tier Six... and so on...
